Older Women May Be Predisposed To Be Less Active

Pushing yourself is harder if you are a woman older than 50. Just ask Meschelle Sevier.

“I would rather sit on the couch at home and watch re-runs,” Sevier says.

Annie Green also has noticed that it’s harder for her to exercise than it used to be. 

“I would probably run on the treadmill two to three minutes and then walk. Now it’s down to one or two minutes.”

Staying active is harder

As women age, it seems to become more challenging to stay active, and this inactivity could lead to weight gain and a host of health problems, such as cardiovascular disease and Type-2 diabetes. The rate of some chronic diseases increases around the time a woman goes through menopause.

Scientists, including Victoria Vieira-Potter at the University of Missouri, are trying to figure out why women become less active as they age and what can be done to promote physical activity.

Vieira-Potter noticed a link between weight gain and the loss of estrogen in lab rats after their ovaries were removed.

However, she also noted that the female rats that exercised and were fit before their ovaries were removed did not gain weight. Vieira-Potter theorized that healthy exercise regimens might protect postmenopausal women from weight gain and its health complications.

Be aware and adjust

Vieira-Potter also theorized that a drop in estrogen leads to a drop in the chemical dopamine that sends signals to the pleasure or reward center in the brain, so women get less pleasure from exercising, and they put on weight.

The key, she said, is for older women to be aware of these changes and to adjust their lifestyles accordingly. 

“We don’t need a lot of activity,” she said, “Women don’t need to take up marathon running because they’re going through menopause.”

Although the research did not involve humans, scientists say animal models are useful. 

A different theory

Dawn Lowe studies aging and exercise at the University of Minnesota. She is involved in a large study of premenopausal and postmenopausal women that includes researchers from a spectrum of disciplines.

These scientists are looking at activity in older women from a different angle. They want to see how women’s health influences physical activity. As women age, they can lose control of their bladders. That lack of control at unexpected moments causes some women to stop exercising because exercise can be one of the causes of incontinence.

“The pelvic floor is composed of muscles. We think about leg muscles becoming weaker with age in men and women, but the pelvic floor is also a muscle. There is growing evidence that that muscle becomes weak with age as well,” Lowe told VOA in a Skype interview.

The result can be involuntary urinary or fecal incontinence, especially during exercise. Nearly 40 percent of the women in the study experienced incontinence. Lowe said there’s growing evidence, particularly for women, that estrogen affects how that muscle works.

Lowe says over the next several years, we can expect to learn a lot about women’s health and how it changes through the menopausal years, with the hope of keeping women active and healthy.

Advanced Trash-to-Fuel Plant Goes Online in Israel

While President Trump’s latest executive order gives renewed life to power plants that burn coal, energy companies continue to seek and find alternative, less expensive and cleaner sources of fuel. One possibility is turning trash into fuel in an environmentally responsible way. VOA’s George Putic reports that authorities in Tel Aviv say their new garbage processing plant is on track to produce as much as 500 tons of fuel daily.

Farmers’ Use of Groundwater for Irrigation Called Unsustainable

Farmers around the world are using an unsustainable amount of well water to irrigate their crops, which could lead to an uptick in food prices as that water runs low, international researchers warned Wednesday.

Farmers are increasing their use of groundwater to grow staple crops such as rice, wheat and cotton, the scientists said. But much of that water use is unsustainable, as water is being pumped out faster than it can be naturally replenished.

“Groundwater depletion is increasing rapidly, especially in the last 10, 20 years, due to the increasing populations and also associated food production,” said Yoshihide Wada, deputy water program director at the International Institute for Applied Systems Analysis, a science organization in Austria.

The shortages are occurring in some big agricultural producers such as India, China and the United States, he said.

But they could have an impact on a much wider area of the world because “much of the agricultural production is traded internationally,” he said.

An estimated 11 percent of crops irrigated with nonrenewable groundwater are traded internationally after harvest, the researchers said in a report published in the journal Nature.

Countries such as Pakistan, Iran and India, which use the most groundwater to grow food, are already suffering from water scarcity, the report said.

For many countries “it doesn’t really make sense that you’re exporting a lot of food that comes from groundwater depletion,” Wada said in an interview with the Thomson Reuters Foundation.

Effect on food prices

Unsustainable use of groundwater could lead to rising future food prices, as countries are forced to spend more money to find water to irrigate their crops, he said.

Depleted supplies of groundwater could also hurt local people, who rely on the water for day-to-day use and for other things, including fighting fires or dealing with other emergencies, the scientists said.

Droughts, which are expected to increase as a result of climate change, could also increase the shortages of groundwater and affect food supplies, lead author Carole Dalin added in a statement.

“Where and how the products are grown is crucial, and basic foods like rice and bread could have a damaging impact on global water supplies,” said Dalin, a research fellow at University College London’s Institute for Sustainable Resources.

Unless both food producers and food buyers adopt strategies to use water more wisely, “most of the world’s population risks seeing increased food prices or disrupted food supply,” she warned.

Wada said governments should more closely monitor the use of groundwater and invest in things like drip irrigation technology, which can dramatically cut water use, to better prepare for the future and conserve natural resources.

PDVSA Manager Arrested in Venezuela Fuel Corruption Probe

Venezuela has arrested a senior manager of state oil company PDVSA on suspicion of “irregularities” in contracts to supply fuel to the domestic market, authorities said on Wednesday.

The detention of international commerce manager Marco Malave, 47, followed a shakeup of personnel at PDVSA’s trade department since January and amid gasoline shortages around the South American OPEC nation last week.

“PDVSA representatives denounced a series of irregularities in the protocol for contracting companies with vessels to supply the referred hydrocarbon to the Venezuelan market,” the state prosecutor’s office said in a statement.

The situation affected fuel distribution in seven states, including the capital Caracas, it said. Malave was arrested last week in Caracas and his bank accounts have been frozen.

Vow to battle corruption

President Nicolas Maduro’s socialist government and Petróleos de Venezuela, S.A., familiarly known as PDVSA, have repeatedly vowed to take steps to combat corruption, which has affected Venezuela and its oil industry for decades.

Earlier this month, the heads of Venezuela-based subcontracting companies Castillo Max and Guevara Training were arrested and charged with corruption for overbilling in equipment sales at the main oil-exporting port Jose.

Jesus Osorio, the former manager of Jose terminal, was jailed in February over the purchase of two floating platforms costing $76.2 million.

Opposition leaders have said that PDVSA has been crippled by malfeasance under 18 years of socialist rule.

A probe last year by the opposition-run Congress said $11 billion had gone missing from PDVSA. The government dismissed that as part of a right-wing smear campaign.

Change at the top?

Rumors are rife inside PDVSA and in the wider oil sector that company president Eulogio del Pino may depart soon, to be replaced by Oil Minister Nelson Martinez. There has been no official word on this. Attempts to reach Del Pino have been unsuccessful.

“Del Pino’s apparent replacement Nelson Martinez is part of this broader trend of promoting loyalists,” Eurasia consultancy analyst Risa Grais-Targow wrote in a report on Wednesday.

“Martinez is close to Maduro, who has long wanted him to head PDVSA. Martinez represents the most viable alternative to Del Pino considering a shallow bench of skilled oil sector technocrats.”

Study Finds Correlation Between Good Health, Economic Prospects

A study by U.S. economic experts and a major health insurance company says a healthy population is a key ingredient in a healthy and growing economy.

Blue Cross and Moody’s Analytics used data from millions of insurance customers to draw a statistical relationship between health and prosperity in the United States.

In counties throughout the 50 states where the population had top health scores, per capita incomes were nearly $4,000 a year higher than in counties where people had just average health scores.  

Unemployment showed a similar pattern: The healthiest counties had a jobless rate eight-tenths of a percent better than communities where health was average. Economic growth also was measurably stronger in the healthiest areas.

The report’s authors cautioned that the statistical correlation did not prove that healthier people cause a stronger economy, but it did make researchers suspect that such a relationship exists. The report also noted that healthier people lose less time from work and bring better skills to the job, because they didn’t miss school lessons.

Obamacare debate

The report came in the midst of a long-running national debate among American lawmakers about how to devise and pay for a system of health insurance.

Since President Donald Trump took office, his Republican Party has been planning to repeal the Affordable Care Act that former President Barack Obama signed into law seven years ago, claiming it is ineffective and financially ruinous.

The sentiment among lawmakers in Congress conflicted with many American families’ feelings about the value of the ACA, also known as Obamacare, and a divided Republican majority in Congress proved unable to repeal or replace the law.

Dirty Air From Global Trade Kills at Home, Abroad, Study Contends

A study that measures the human toll of air pollution from global manufacturing and trade demonstrates how buying goods made far away can lead to premature deaths both there and close to home.

Each year, more than 750,000 people die prematurely from dirty air generated by making goods in one location that will be sold elsewhere. That’s about one-fifth of the 3.45 million premature deaths from air pollution. The study says 12 percent of that total number of deaths, or about 411,000 people, are a result of air pollution that has blown across national borders.

“It’s not a local issue anymore,” said study co-author Dabo Guan, an economist at the University of East Anglia in England. “It requires global cooperation.”

Multiple factors

It has long been known that that the environmental burden of manufacturing often falls heaviest on countries where companies set up shop to take advantage of low labor costs and relatively loose environmental regulations. But this is the first study to bring together economic, manufacturing, trade, atmospheric and health data to calculate the number and location of premature deaths from air pollution.

It found that people in Western Europe buying goods made elsewhere were linked to 173,000 overseas air pollution deaths a year, while United States consumption was linked to just over 100,000 deaths, according to the study published in Wednesday’s journal Nature.

In China, 238,000 deaths a year are associated with production of goods that are bought or consumed elsewhere, the study said. That number is 106,000 deaths in India and 129,000 deaths in the rest of Asia.

“We have a role in the quality of the air in those areas,” study co-author Steven Davis, an atmospheric scientist at the University of California-Irvine, said in an interview. “We’re taking advantage of our positon as consumers, distant consumers.”

Local effects

Still, the study said three-quarters of the 1 million yearly air pollution deaths in China and the nearly half a million deaths in India result from production of goods that are consumed locally.

China and India also have pollution that travels elsewhere and kills between 65,000 and 75,000 people in other countries, the study said. India’s migrating pollution kills more because China’s pollution, which hits Japan and South Korea, often heads over the Pacific Ocean, where its effects dissipate over the miles, Davis said. India’s pollution heads directly to more populous neighboring countries.

The study starts by looking at the 3.45 million deaths a year that this and other studies say are triggered by tiny airborne particles often called soot or smog. About 2.5 million of those deaths are associated with the making and consuming of goods, including the energy needed to produce and ship them. The rest are due to natural factors like dust, fires and other causes that can’t be tracked, said study lead author Qiang Zhang, an atmospheric chemist at Tsinghua University in Beijing.

Like smoking, air pollution increases the risk of getting diseases like heart disease and stroke, said study co-author Michael Brauer, a public health professor at the University of British Columbia. Using well-established methods, researchers calculate death estimates using health statistics, pollution levels and other factors.

Dr. Howard Frumkin, a former director of the National Center for Environmental Health at the U.S. Centers for Disease Control and Prevention now at the University of Washington, was not part of the study but praised it. He said the calculations done by the study are crucial for understanding the larger problem.

Scientific approach seen vital

“This is a moral question as much as a scientific one,” Frumkin wrote in an email. “But the scientific approach here — linking data on manufacturing and associated pollution emissions, import and export flows, pollutant movement across national boundaries, and the health impact of pollution exposure — is exactly what’s needed.”

Producing more goods locally would change where deaths occur and potentially reduce overall deaths — if local emissions rules are tighter. Bringing back manufacturing to the United States, as President Donald Trump and politicians from both parties want, would bring more air pollution deaths to the U.S., but reduce deaths worldwide because pollution laws are stricter, Davis and others said.

Production is likely to remain concentrated in Asia, however, and it will have to be up to those countries to better regulate their own industrial emissions, said Peter Adams, an engineering professor and air pollution expert at Carnegie Mellon University in Pittsburgh, who wasn’t part of the study. “Relying on consumer altruism,” he said, won’t be enough.

Tackling Global Health Care: Tips for Aspiring Entrepreneurs

Imagine a vaccine vial with a temperature-sensitive label that changes colors when exposed to excessive heat.

That’s the sort of technology that can make a huge difference for doctors working in challenging conditions, allowing them to determine at-a-glance whether heat-sensitive vaccines are viable.

The vaccine vial monitor is one of the projects at the Program for Appropriate Technology in Health (PATH), an international nonprofit based in Seattle with more than 22 offices around the world, including sub-Saharan Africa, India and Southeast Asia.

The organization partners with foundations, non-governmental organizations and governments to expedite the development of global health solutions such as vaccines, drugs and medical devices. PATH’s aim is to help deliver breakthroughs in drug and medical devices on a global scale.

Tribendimidine (TrBD) is one of those potential breakthroughs — a drug treatment for soil-transmitted helminths, or intestinal worm infections.

According to the World Health Organization, over 1.5 billion people, or 24 percent of the global population, have acquired soil-transmitted helminths infections. Tropical and subtropical regions of the world are most affected, with the highest rates of incidences in sub-Saharan Africa, the Americas, China and East Asia.

The development of new drugs like TrBD helps deter increasing resistance to existing drugs, when used in tandem with or as a replacement for these drugs.

Advice for entrepreneurs

David Shoultz, program leader for drug development at PATH, considers three factors essential to the long-term success of health care solutions, and advises aspiring entrepreneurs to keep them in mind: demand, cost and consumer-oriented product design.

“Unless we understand what the user is looking for and if we can then actually project what the demand will be … any technology, no matter how good it is, is likely to fall flat,” he said.

Shoultz recommends entrepreneurs find partners who can be a bridge into the global health arena.

“It may be that the entrepreneur truly does have a brilliant idea and it’s already available in a different setting,” he said. Organizations like PATH and the Bill and Melinda Gates Foundation can help filter and shape ideas, along with facilitating important industry connections.

Cost is another important consideration for entrepreneurs. Medical technologies developed in high-income countries can be less accessible to those in middle- or low-income countries, which is why Shoultz advises entrepreneurs to keep prices as low as possible.

For example, PATH’s drug for soil-transmitted helminths will sell for $0.06 to $0.07 cents a tablet.

“To be honest, there are comparable drugs that are even a little bit less expensive than that,” noted Shoultz, “We’re constantly trying to think of, OK, how could we make it even a little bit less expensive.'”

WATCH: Shoultz Talks about Common Mistakes by Entrepreneurs

Ultra Rice

Global entrepreneurs should also consider end-users not just as patients, but as consumers, Shoultz said.

“Sometimes we think about consumers or users in low-income settings as being very utilitarian, and in fact, my experience … is that they’re looking for the same thing that all of us are looking for in consumer goods — they do want to be excited and delighted,” he said.

To that end, PATH developed a rice fortification technology called Ultra Rice in which grains made from rice flour are fortified with vitamins and minerals and produced to resemble real rice grains. The Ultra Rice grains are then mixed with local, natural rice supplies to significantly boost their nutritional value.

The product aids those around the world suffering from micronutrient deficiencies, of which the United Nations World Food Program says there are 2 billion.

“I think really understanding the consumer impulse … is critically important, rather than just imagining that we’re going to build drab or utilitarian tools, because that’s not very exciting to consumers, regardless of their income level,” Shoultz said.

Silicon Valley Experts Help International Startups Struggling With Growth

When he was growing up in Hyderabad, India, Ravindra Sunku, 52, could see and smell the burning kerosene and wood his neighbors used to cook.

It stuck in his memory people he knew might have suffered from lung disease caused from what they inhaled by doing something as simple as cooking dinner.

Now a tech executive in Silicon Valley, Sunku recently was able to use his professional skills to help a Kenyan organization that makes clean cook stoves that promise to save lives and reduce deforestation. 

“I’ve grown up in India.  I’ve seen the hardship,” he said.  “This could have saved someone in my childhood.”

Sunku volunteered through RippleWorks, a unique mentorship program in Silicon Valley that connects tech professionals with startups around the world that have a social mission.

RippleWorks has helped 28 projects and plans to help 40 more this year.  It picks firms that are focused improving education, healthcare, clean energy technology and financial access.

The companies helped include NeoGrowth, a firm in Mumbai, India, that provides access to short-term loans for small businesses.  Another is Zoona, which uses technology to provide financial services for people in places such as Malawi and Zambia.  In Mexico City, RippleWorks has connected a tech marketing expert with Cignifi, which provides credit to customers via mobile phones.

There are many global mentorship programs and startup incubators bringing together tech experts with entrepreneurs in developing countries. But RippleWorks  focuses on advising firms that have already launched and have found their niche.

It offers what its founder calls “mentorship in a box.”  The organization identifies a key problem for the companies and pairs them with an expert who has done the job before.  Then RippleWorks manages the project, setting up weekly video-conference meetings.

Doug Galen, RippleWorks co-founder and CEO, says the organization’s “secret sauce” is “project management to keep everyone on task.”

Tech Veterans Helping With Growth Hurdles

Sunku’s life took him from Hyderabad to Oklahoma, where he received a masters degree in industrial engineering.  He worked in a sheet metal factory near Los Angeles before heading to the San Francisco Bay Area where he worked in software.

As he juggled work and family, Sunku did volunteer stints in his community – all involving physical labor, such as building a playground or stuffing grocery bags for a food bank.

He had not considered that his job skills would be useful as well to a non-profit until he met RippleWorks and began his six-month volunteer stint with Burn Manufacturing in Nairobi, Kenya.  Since 2013, Burn has distributed 250,000 clean cook stoves.

Since its launch, Burn had grown big fast, with a factory, employees, products and customers.  It needed technology to track and manage everything from sales to payroll to supplies.

That’s where Sunku came in.

Once a week, Sunku arrived at work in San Francisco at 7 a.m. to video conference with the chief financial officer and general manager at Burn.  He also worked an additional two hours on the weekend on Burn-related projects and put in an additional hour working with the RippleWorks project manager.

Sunku is director of IT at StitchFix, a digital personalized fashion company.  He worked with the Burn team on its needs before acquiring a software system that would enable the organization to run more smoothly.  He also helped them create criteria for hiring technical help in Nairobi.

“It took me a bit to get comfortable,” he said.  “But once I could see that they were taking to what I was saying, it felt gratifying.”

Sunku’s experience culminated with a trip to Nairobi to work with Burn, which he was able to do because his firm, StitchFix, gives workers unlimited time off.

For Sunku, the experience was eye-opening.

“I never thought someone like me, originally from India who moved to the U.S. and has been in this country for more than 30 years, would make a contribution to Africa.”

US Vote to Repeal Broadband Privacy Rules Sparks Interest in VPNs

The vote by the U.S. Congress to repeal rules that limit how internet service providers can use customer data has generated renewed interest in an old internet technology: virtual private networks, or VPNs.

VPNs cloak a customer’s web-surfing history by making an encrypted connection to a private server, which then searches the Web on the customer’s behalf without revealing the destination addresses. VPNs are often used to connect to a secure business network, or in countries such as China and Turkey to bypass government restrictions on Web surfing.

Privacy-conscious techies are now talking of using VPNs as a matter of course to guard against broadband providers collecting data about which internet sites and services they are using.

“Time to start using a VPN at home,” Vijaya Gadde‏, general counsel of Twitter Inc, said in a tweet on Tuesday that was retweeted by Twitter Chief Executive Jack Dorsey.

Gadde was not immediately available for comment. Twitter said she was commenting in her personal capacity and not on behalf of the company.

The Republican-led U.S. House of Representatives voted 215-205 on Tuesday to repeal rules adopted last year by the Federal Communications Commission under then-President Barack Obama to require broadband providers to obtain consumer consent before using their data for advertising or marketing.

Sensitivity to Certain Sounds Is a Real Thing

Do you ever shudder when you hear certain sounds, such as rustling of some type of plastic bags or a fork scraping on the bottom of a porcelain plate? Or get a tingling in your teeth when somone scrapes their fingernails on a blackboard?

It may be a mild annoyance for most, but a serious problem for people with “misophonia,” from the Greek words meaning hatred of sound.

No matter how tolerant we are, most of us feel uncomfortable if a person sitting close to us in a quiet cinema starts noisily opening a bag of chips and loudly eating them. 

But for some people, who suffer from misophonia, certain repetitive noise can be hardly bearable.

“Mainly sounds made by people’s mouth or breathing. This is certain speech sounds, chewing, certain other sort of noisy wet noises from the mouth, noisy breathing as well. Other ones include things like repetitive noises, pen clicking, foot tapping, keyboards sometimes, packets rustling,” Will Sedley of New Castle University said.

Physical evidence?

Scientists at the Newcastle University wanted to see whether there is a physical evidence of this sensitivity.

Volunteers were asked to rate the level of unpleasantness of different sounds from neutral, such as rainfall or the sound of boiling water, to irritating, like noisy eating, loud breathing or a baby crying.

Their brain scans showed that misophonia has to do with the size of an area in our brains that regulates emotional responses.

“It was smaller and less developed in people with misophonia at a group level. Nothing you’d see on an individual brain screen basis, but suggesting that there may actually be brain structural alterations,” Sedley said.

But the discovery opened new questions.

“It’s difficult to know which is the chicken and which is the egg, whether this is the cause of misophonia or in part, or whether this is the consequence of having this condition or an unpleasant adversant condition like this and how it affects the brain in the long term,” he said.

Scientists say they also want to find out whether severe misophonia is treatable, but they say everybody should be aware that some people are genuinely sensitive to certain noises.

US Vice Admiral Calls for Code of Conduct for Space

The deputy commander of the U.S. Strategic Command is calling for the development of a code of conduct for space as dreams of altruistic exploration fade.

Vice Admiral Charles Richard believes establishing norms and practices of behavior in space would help nations better understand each other’s activities.

“We’re still sorting out what constitutes an attack in space,” Richard said at a conference titled “Space Security: Issues for the New U.S. Administration” held last week at the Center for Strategic and International Studies in Washington.

“What is the indisputable evidence required within the international community to assert violation of sovereign territory in space? What constitutes provocation in space from our point of view?” he asked.

No rules of engagement in space

Conducting exercises with U.S. partners and allies has revealed the difficulty of answering those questions because there are no rules of engagement for space, said Richard.

While acknowledging that “space is different,” said Richard, “Some of the questions we are answering have already been answered in the maritime domain and in the air domain so we have precedent to start from.”

For decades, the roadmap for the arena was the Outer Space Treaty of 1967  signed by Russia and the United States during the Cold War, which has now been signed by 105 nations and signed but not ratified by 24 more.

The agreement bans placing nuclear weapons or weapons of mass destruction in Earth orbit, on the moon or on any other celestial real estate. It further forbids, “the establishment of military bases, installations and fortifications, the testing of any type of weapons and the conduct of military maneuvers on celestial bodies shall be forbidden.”

Over 1,400 satellites orbiting Earth

There are loopholes in the treaty’s language. It did not prohibit the use of conventional weapons or ban military forces from space as long as they undertook non-aggressive activities, such as scientific research or launching satellites for spying and communications. (As of July 2016, there were 1,419 satellites orbiting Earth, about 350 of them for military use, according to the Union of Concerned Scientists, which maintains a database.)

The wake-up call came in 2007 when China shot down an aging Fengyun-1C weather satellite while testing an anti-satellite (ASAT) device mounted on a ballistic missile. The test shattered the satellite into more than 2,000 pieces and, for many, solidified the notion of space as a theater of war.

In 2015, the U.S.-China Economic and Security Review Commission called for more study of China’s counterspace program in its annual report to  Congress. On March 22, an official from the U.S. Strategic Command told VOA that the U.S. military and China have had several dialogues on space security and hoped that the dialogue would continue.

Safe, stable and secure

Peter Hays, a professor of space policy at the U.S. Department of Defense and a professor of space policy at the George Washington University Institute of Space Policy, said at the March 22 conference that the U.S. should not be the first country to deploy weapons to space, but it should be prepared.

Richard said that while the U.S. would never want to extend war into space, the question today is “How do we deter our adversaries in space while keeping it safe, stable and secure? … Whether you’re guiding ships, jets, drones or missiles, space is the domain that enables all others.

“If we have an agreed-to set of norms and behaviors, now you start to minimize the chance of miscommunication,” he said, adding that minimizing the chances of misinterpretation also reduced the likelihood of “an inappropriate or disproportionate response.”

Space Laboratory the Size of a Tissue Box

A tiny satellite launched by India that is circling the earth contains a laboratory that is only the size of a tissue box.

California, Washington Face Off Over Vehicle Fuel Standards

California and a dozen other states could be heading for a showdown with the federal government as the Trump administration reviews rules on fuel efficiency and vehicle emissions, rules President Donald Trump has said curtail growth in the auto industry.

California has a waiver under federal law to set its own standards, and other states have the option to follow them.

California has been a leader in promoting fuel-efficient cars and sport utility vehicles, and the state says it will keep its strict standards, despite a review of federal regulations ordered by Trump.

Separately, the president signed an executive order Tuesday to reduce the federal role in regulating carbon emissions in the energy industry to promote “energy independence,” although scientists view carbon emission from fossil fuels as a major cause of global warming.

Vehicle fuel standards were strengthened in the final days of the Obama presidency, as the administration hurriedly completed a review of fuel economy targets through 2025, imposing goals that bring a corresponding reduction in tail-pipe emissions.  

Fueled by 1973 oil embargo

Therese Langer of the American Council for an Energy-Efficient Economy says Obama was continuing a process that started in California in the 1960s, then moved to the rest of the country with federal legislation.

After the Arab oil embargo of 1973, Congress set targets with the CAFE, or Corporate Average Fuel Economy standards.

Langer says the rules helped reduce dependence on foreign oil, but “the dominant effect of bringing down that pollution from tail pipes of cars through a combination of changes to the cars and changes to the fuel is a human health benefit. And it’s really hard to overstate how dramatic that has been over the years.”

CAFE fuel economy standards are locked in through 2021, but the Trump administration is reconsidering the rules for the following years through 2025.

Supporters say strict standards help to cut the greenhouse gases that are fueling global warming, save consumers money, and reduce U.S. dependence on foreign oil.

The president says he wants to cut government regulations.

Thomas Pyle of the industry-aligned American Energy Alliance says the president’s review will ask, “How [do] you balance the desire for fuel efficiency, for more fuel-efficient vehicles, with other things that are important when consumers go and purchase vehicles, such as size, safety, whether or not they need a truck for their job.”

Environmentalists push electric cars

Existing standards aim to improve fuel economy by promoting hybrid gasoline-electric and battery-powered electric vehicles.

Electric vehicles, or EVs, are just one percent of the market and pose a special challenge. Environmentalists say they have great promise, but need government incentives to spur development.

Laura Renger oversees air and climate issues for Southern California Edison, and she says the electric utility company is doing its part.

Renger drives an electric car to work and charges it outside the company office. She says EV drivers like her feel “range anxiety,” but the utility is installing 1,500 charging stations where people park their cars, “on campuses, work places, and shopping centers.”

Other companies are engaged in similar programs.

Renger says the market will expand as battery technology gets better and the charging infrastructure grows.

Critics say that government subsidies for electric vehicles are not needed, and Pyle, of the American Energy Alliance, says people who drive EVs can afford to do it without tax breaks.

Finding ‘the right balance’

Jessica Caldwell of the auto research site Edmunds.com disagrees, and she says online behavior shows that buyers are sensitive to price and are looking for incentives.

“People in real time are very deal oriented,” she said, “so my fear is if you take away the federal subsidy, this market is really going to collapse,” she said.

California says it has no intention of removing its subsidies.

Langer, of the American Council for an Energy-Efficient Economy, says current government fuel-and-emission standards help consumers.

“If you look at the whole time period for which the standards were adopted under the last administration, that’s model year 2012 through 2025,” she said, “the consumer savings from buying less gasoline exceed a trillion dollars.”

But critics like Pyle ask, “What is the right balance, and who makes those choices, the government, or consumers and the auto industry together?”

He applauds Trump’s goal of improving the productivity of the energy and auto industries.

Twelve other states and the U.S. capital now follow the California standards, and if federal rules are weakened, car makers confusingly could face two different sets of vehicle standards, one based on California’s rules and one on Washington’s.

Lawmakers: Trump Team Wants More NAFTA Access for US Goods, Services

Trump administration trade officials want a revamped North American Free Trade Agreement to improve access for U.S. farm products, manufactured goods and services in Canada and Mexico, said lawmakers who met with them Tuesday.

Members of the House Ways and Means Committee met with Commerce Secretary Wilbur Ross and acting U.S. Trade Representative Stephen Vaughn to discuss the administration’s plans for renegotiating the 23-year-old trade deal.

Representative Bill Pascrell, a New Jersey Democrat, said Ross told lawmakers in the closed-door session that the administration was still aiming to complete NAFTA renegotiations by the end of 2017.

‘Ambitious’ schedule

That time frame is viewed by some members as “ambitious,” especially because it is not clear when the administration will formally notify Congress of its intention to launch NAFTA renegotiations, Pascrell said.

The notification will trigger a 90-day consultation period before substantial talks can begin. Tuesday’s meeting was a legal requirement to prepare the notification and preserve the “fast track” authority for approving a renegotiated deal with only an up-or-down vote in Congress.

President Donald Trump has long vilified NAFTA as draining millions of manufacturing jobs to Mexico, and he has vowed to quit the trade pact unless it can be renegotiated to shrink U.S. trade deficits.

Lawmakers said Ross and Vaughn discussed broad negotiating objectives, but did not get into specific issues such as U.S. access to Canada’s dairy sector or rules of origin for parts used on North American-assembled vehicles.

Key objectives

Ways and Means Committee Chairman Kevin Brady, a Texas Republican, told reporters that market access, modernizing NAFTA and “holding trading partners accountable” were key objectives articulated by Ross and Vaughn.

“They were very clear. They want to open access in ag, manufacturing and services as well, so they want this to be a 21st-century agreement,” Brady said.

Spokesmen for the Commerce Department and USTR were not immediately available for comment on the meeting.

Lawmakers said the administration has not settled on the form of the negotiations, whether NAFTA will remain a trilateral agreement or whether it would be split into two bilateral trade deals.

“My sense is that they are not prejudging the form. They are focused on the substance of the agreement itself with Mexico and Canada,” Brady said.

Some lawmakers expressed frustration that the Trump officials were short on specific answers.

“I wouldn’t exactly call this meeting as moving the ball forward very much,” said Representative Ron Kind, a Wisconsin Democrat.

New Blood Test Rapidly Diagnoses Tuberculosis

Researchers have developed a blood test that can rapidly tell whether someone is suffering from tuberculosis. Investigators hope the test can lead to quicker treatment, making a dent in the worldwide TB epidemic.

One-third of the world’s population is infected with a silent form of tuberculosis, according to the World Health Organization. A person can live for years infected with latent TB and show no symptoms.  

But each year, 10 million people develop active TB, which causes severe symptoms — such as coughing, weight loss, fever and night sweats — and kills about 2 million of those people. Prompt diagnosis and treatment is critical for containing the highly contagious disease and saving lives.  

The new blood test promises to provide that speedy diagnosis. Investigators say it can tell within hours whether someone is infected with mycobacterium, the pathogen that causes tuberculosis.

Currently, TB diagnosis is done with a sputum test. The objective is to grow the bacterium in culture from expelled mucus.

Arizona State University bioengineering professor Tony Hu, who helped develop the new test, said the sputum test takes too long.

“That technology needs four to eight weeks to get the final result,” he said. But for the blood test, it’s “only 2½ hours.”

Detects peptides

Called Nanodisk-MS, the rapid TB test takes advantage of nanotechnology to detect minute levels of peptides in the blood. Peptides are amino acid fragments of proteins that TB bacteria release only during active infections.

The highly sensitive blood test, described in the journal Proceedings of the National Academy of Sciences, can also measure the severity of the infection.

Nanomedicine such as this, Hu said, could also be used to monitor patients who are being treated with antibiotics to see how well they are responding or whether the antibiotic cocktail is the right one. He called it a form of personalized medicine that “can really save lives.”

Hu said the test needed further validation in clinical trials, but that he hoped it would become part of the arsenal in the global war on tuberculosis.

Brazil Police Raid Brokerage for Allegedly Laundering ‘Car Wash’ Bribe Cash

Brazil’s federal police on Tuesday raided a brokerage in Rio de Janeiro which they allege helped launder money for corrupt former executives of state-run oil firm Petrobras, as part of their sprawling “Car Wash” anti-graft probe.

Police said they searched the offices of the Advalor Distribuidora de Titulos e Valores brokerage firm in Rio, which they allege facilitated the movement of bribes from big construction firms to the then-Petrobras executives, often to their overseas bank accounts.

A person who answered the phone at Advalor’s Rio de Janeiro office did not respond to requests for comment.

Goncalves arrested

Former Petrobras executive Roberto Goncalves was arrested in Tuesday’s operation on the order of federal judge Sergio Moro, who oversees Operation Car Wash.

Police allege Goncalves received at least $5 million in bribes paid into overseas bank accounts.

The arrest warrant issued by Moro states that Goncalves had at least five Swiss bank accounts. In just one of those, he received $3 million in bribes from construction giant Odebrecht, according to police.

Allegedly took bribes for several projects

Goncalves allegedly took bribes in connection with several projects, one of the largest being a contract awarded to a consortium composed of Odebrecht and UTC Engenharia for work on the Comperj refinery outside Rio de Janeiro.

He does not yet face any formal charges. Under Brazilian law, only prosecutors can level charges. The prosecutor’s office did not respond to request for comment about Goncalves’ case.

A lawyer for Goncalves could not immediately be reached.

Elon Musk’s Latest Target: Brain-computer Interfaces

Tech billionaire Elon Musk is announcing a new venture called Neuralink focused on linking brains to computers.

The company plans to develop brain implants that can treat neural disorders —  and that may one day be powerful enough to put humanity on a more even footing with possible future superintelligent computers, according to a Wall Street Journal report citing unnamed sources.

Musk, a founder of both the electric-car company Tesla Motors and the private space-exploration firm SpaceX, has become an outspoken doomsayer about the threat artificial intelligence might one day pose to the human race.

Continued growth in AI cognitive capabilities, he and like-minded critics suggest, could lead to machines that can outthink and outmaneuver humans with whom they might have little in common.

In a tweet Tuesday, Musk gave few details beyond confirming Neuralink’s name and tersely noting the “existential risk” of failing to pursue direct brain-interface work.

 

Stimulating the brain

Some neuroscientists and futurists, however, caution against making overly broad claims for neural interfaces.

Hooking a brain up directly to electronics is itself not new. Doctors implant electrodes in brains to deliver stimulation for treating such conditions as Parkinson’s disease, epilepsy and chronic pain. In experiments, implanted sensors have let paralyzed people use brain signals to operate computers and move robotic arms. Last year , researchers reported that a man regained some movement in his own hand with a brain implant.

Musk’s proposal goes beyond this. Although nothing is developed yet, the company wants to build on those existing medical treatments as well as one day work on surgeries that could improve cognitive functioning, according to the Journal article.

Neuralink is not the only company working on artificial intelligence for the brain. Entrepreneur Bryan Johnson, who sold his previous payments startup Braintree to PayPal for $800 million, last year started Kernel, a company working on “advanced neural interfaces” to treat disease and extend cognition.

Risk of overhype

Neuroscientists posit that the technology that Neuralink and Kernel are working on may indeed come to pass, though it’s likely to take much longer than the four or five years Musk has predicted. Brain surgery remains a risky endeavor; implants can shift in place, limiting their useful lifetime; and patients with implanted electrodes face a steep learning curve being trained how to use them.

“It’s a few decades down the road,” said Blake Richards, a neuroscientist and assistant professor at the University of Toronto. “Certainly within the 21st century, assuming society doesn’t implode, that is completely possible.”

Amy Webb, CEO of Future Today Institute, pointed out that the Neuralink announcement is part of a much larger field of human-machine interface research, dating back over a decade, performed at the University of Washington, Duke University and elsewhere.

Too much hype from one “buzzy” announcement like Neuralink, she said, could lead to another “AI Winter.” That’s a reference to the overhype of AI during the Cold War, which was followed by a backlash and reduced research funding when its big promises didn’t materialize.

“The challenge is, it’s good to talk about potential,” Webb said. “But the problem is if we fail to achieve that potential and don’t start seeing all these cool devices and medical applications we’ve been talking about then investors start losing their enthusiasm, taking funding out and putting it elsewhere.”

US Consumer Confidence Surges in March

U.S. consumer confidence, home prices, and the trade deficit all improved, according to economic reports published Tuesday.

Consumer confidence hit a 16-year high, as consumers said they were more confident about getting or keeping jobs and the economic outlook in general. The Conference Board said its index jumped more than nine percentage points in March.

Experts track consumer attitudes for clues about the consumer spending that drives most U.S. economic activity.

A separate report by S&P Case-Shiller showed home prices rose sharply over the past 12 months, increasing at the fastest pace since July 2014.  Some buyers may have speeded up home purchases to avoid further expected interest-rate hikes.  Experts say prices are rising in part because demand for homes is outstripping the supply.

In a separate report, the Census Bureau said the trade deficit shrank as imports dropped sharply. The deficit means that U.S. consumers buy more from foreign companies than Americans are selling to customers abroad.

Ford Investing $1.2B in 3 Michigan Plants, Adding 130 Jobs

Ford Motor Co. is investing $1.2 billion in three Michigan facilities, including an engine plant where it plans to add 130 jobs.

President Donald Trump, who has pressured automakers to invest more and create jobs in the U.S., applauded the move Tuesday in an early morning tweet.

“Big announcement by Ford today. Major investment to be made in three Michigan plants. Car companies coming back to U.S. JOBS! JOBS! JOBS!,” Trump tweeted hours ahead of the announcement.

The investments were in the works well before Trump took office, however. Ford announced plans to upgrade some of its Michigan plants in November 2015 as part of a new contract with the United Auto Workers union.

Ford Americas President Joe Hinrichs said the company told the White House about the investments Tuesday morning. Hinrichs said it’s not unusual for the company to reach out to state and national political leaders before such an announcement.

Hinrichs said Tuesday’s announcement was timed to a state meeting where officials approved nearly $31 million in grants and 15-year tax exemptions for Ford.

Ford will spend $850 million to upgrade the Michigan Assembly Plant next year to build the Ford Ranger midsize pickup and Ford Bronco SUV. Ford plans to build the Ranger starting at the end of 2018 and the Bronco starting in 2020.

The suburban Detroit plant currently makes small cars, which are moving to a plant in Mexico. Trump has needled Ford and other automakers in the past about plans to move small car production to Mexico. Amid slowing sales of smaller vehicles, Ford did scrap plans for a brand new plant in Mexico, but will continue to build small cars at an existing facility there.

Hinrichs said the Michigan Assembly Plant will operate on two shifts unless demand dictates that a third shift be added. The plant used to operate on three shifts, but it cut a shift and 673 factory workers in 2015 because of slumping sales of small cars.

Ford will spend $150 million to upgrade its Romeo Engine Plant outside Detroit. The company says it will create or retain 130 jobs at that plant, which will make components for a new engine.

Ford also is spending $200 million on a data center that will store information collected from self-driving and connected cars. The data center will be located at an assembly plant in the Detroit suburb of Flat Rock. Ford announced in January that the Flat Rock plant would get $700 million in upgrades and 700 new jobs to make electric and self-driving cars.

Ford shares rose 2.2 percent to $11.71 in afternoon trading.

Samsung Plans to Sell Refurbished Galaxy Note 7s

Tech giant Samsung Electronics plans to sell refurbished versions of the Galaxy Note 7 smartphones, the company said late on Monday, signaling the return of the model pulled from markets last year because of fire-prone batteries.

Samsung’s Note 7s were permanently scrapped in October after some phones self-combusted, prompting a global recall roughly two months after the launch of the near-$900 devices.

A subsequent investigation found manufacturing problems in batteries supplied by two companies — Samsung SDI Co and Amperex Technology.

Analysis from Samsung and independent researchers found no other problems in the Note 7 devices except the batteries, raising speculation that Samsung will recoup some of its losses by selling refurbished Note 7s.

A person familiar with the matter told Reuters in January that it was considering the possibility of selling refurbished versions of the device or reusing some parts.

Samsung’s announcement that revamped Note 7s will go back on sale, however, surprised some with the timing – only days before it launches its new S8 smartphone on Wednesday in the United States, its first new premium phone since the debacle last year.

Under pressure to turn its image around after the burning battery scandal, Samsung had previously not commented on its plans for recovered phones.

“Regarding the Galaxy Note 7 devices as refurbished phones or rental phones, applicability is dependent upon consultations with regulatory authorities and carriers as well as due consideration of local demand,” Samsung said in a statement.

South Korea’s Electronic Times newspaper, citing unnamed sources, said on Tuesday that Samsung will start selling refurbished Note 7s in its home country in July or August and will aim to sell between 400,000 and 500,000 of the Note 7s using safe batteries.

Samsung said in a statement to Reuters that the company has not set specifics on refurbished Note 7 sales plans, including what markets and when they would go on sale, though it also said it does not plan to sell refurbished Note 7s in India or the United States.

The company said refurbished Note 7s will be equipped with new batteries that have gone through Samsung’s new battery safety measures.

“The objective of introducing refurbished devices is solely to reduce and minimize any environmental impact,” it said.

The company estimated that it took a profit hit of $5.5 billion over three quarters because of the Note 7’s troubles. It had sold more than 3 million of the phones before taking the model off the market.

Samsung also plans to recover and use or sell reusable components such as chips and camera modules, as well as rare metals such as copper, gold, nickel and silver from Note 7 devices it opts not to sell as refurbished products.

Environment rights group Greenpeace and others had urged Samsung to come up with environmentally friendly ways to deal with the recovered Note 7s. Greenpeace said in a separate statement on Monday that it welcomed Samsung’s decision and that the company should carry out its plans in a verifiable manner.

Souq.com says Amazon has Bought it After $800M Counteroffer

Amazon purchased the Middle East’s biggest online retailer Souq.com on Tuesday for an undisclosed amount, a day after a state-backed firm disclosed an $800 million counteroffer.

 

A joint statement described the purchase as expanding Amazon’s influence into the Mideast as the state-supported firm Emaar prepares to launch its own retail website in a country known more for its luxury malls than online shopping.

 

That could put Seattle-based Amazon in a head-to-head competition with a firm helmed by one of the sheikhdom’s favored business magnates.

 

“This is a milestone for the online shopping space in the region,” Souq.com co-founder and CEO Ronaldo Mouchawar said in a statement.

 

The announcement said the two companies expect the sale to close this year.

 

“Together, we’ll work hard to provide the best possible service for millions of customers in the Middle East,” Russ Grandinetti, a senior vice president at Amazon, said in a statement.

 

On Monday, Emaar Malls PJSC made public its bid for Souq.com in a filing on the Dubai Financial Market. The short filing, signed by Emaar Malls vice chairman Ahmad Thani al-Matrooshi, said the bid was made “in line with the strategy to align e-commerce with physical shopping.”

 

Rumors about Amazon’s interest in Souq.com have circulated for months. In November, Emaar chairman Mohamed Alabbar reportedly met Amazon CEO Jeff Bezos at the state-backed firm’s cavernous Dubai Mall, home to a massive aquarium and in the shadow of the Burj Khalifa, the world’s tallest building it built.

 

Dubai, the commercial capital of the United Arab Emirates, home to the long-haul carrier Emirates and the world’s busiest international airport, also has luxury malls that even include an indoor ski slope. Its summer heat of over 50 degrees Celsius (122 degrees Fahrenheit) makes malls a major attraction for both shopping and leisure time in the city.

 

While Uber and other online services firms work in Dubai, online retail shopping has yet to truly take off like it has in Western countries.

This Day in History: America’s Worst Nuclear Fears Realized at Three Mile Island Plant 

Thirty-eight years ago today — March 28, 1979 — disaster struck at 4 a.m. at the Three Mile Island (TMI) nuclear power plant in central Pennsylvania after its cooling system failed.

It remains the worst nuclear accident in American history.

A simple plumbing failure prevented the main feedwater pumps from sending water to generators that remove heat from the plant’s core reactor.  

During those pre-dawn hours, the temperature of the reactor rose steadily even as staffers were unaware that a valve in the emergency cooling system had become stuck in place, allowing cool water to flow through the valve — not reaching the reactor. 

Instruments in the control room misled operators, who thought the cooling system was working normally.

As coolant flowed from the primary system through the valve, other instruments available to reactor operators provided inadequate information. There was no instrument that showed how much water covered the core. As a result, plant staff assumed that as long as the pressurizer water level was high, the core was properly covered with water. 

As alarms rang and warning lights flashed, the operators did not realize that the plant was experiencing a loss-of-coolant accident — or, rather, the beginnings of a nuclear meltdown.  And just after 6:00 am, data indicated the core reactor had overheated so much that radiation was detected inside the control room.

Half the core was later found to have melted. 

By the evening of March 28, the core appeared to be adequately cooled and the reactor appeared to be stable. 

But new concerns arose by the morning of March 30.

A significant release of radiation from the plant’s auxiliary building, performed by operators to relieve pressure on the primary system and avoid curtailing the flow of coolant to the core, sparked public concerns and consternation among politicians. 

​In an atmosphere of growing uncertainty and concern, then-Governor Dick Thornburgh, consulted with the Nuclear Regulatory Commission (NRC) about evacuating the population near the plant.

Eventually, he and NRC Chairman Joseph Hendrie agreed that it would be prudent for those members of society most vulnerable to radiation to evacuate the area.

Thornburgh announced that he was advising pregnant women and pre-school-age children within a five-mile (8 km) radius of the plant to leave the area.

The national and international media had given the accident at Three Mile Island front page attention for days.  Then-President Jimmy Carter decided a frightened nation needed his presence. On April 1, Carter went to inspect the damaged plant.

In the months following the accident, questions were raised about possible adverse effects from radiation on human, animal and plant life around the nuclear power plant, although none could be directly correlated to the accident. 

Thousands of environmental samples of air, water, milk, vegetation, soil and foodstuffs were collected by various government agencies monitoring the area. 

In 1997, researchers from Environmental Health Perspectives, the journal of the U.S. National Institute of Environmental Health Science concluded increases in lung cancer and leukemia near the Pennsylvania plant suggested a much greater release of radiation during the 1979 accident than had been believed.

The accident sparked sweeping safety regulations. The damaged reactor, on the Susquehanna River near Harrisburg, was never restarted. No new commercial nuclear power plant was licensed by the federal government until 2012.

But an article written by Michael Grunwald published in Time magazine in 2009 summed up Three Mile Island this way:

“The TMI fiasco was a scary cultural moment…But there was nothing particularly tragic about it. It didn’t kill people. It didn’t kill nuclear power.”

Indiana Board Set to Endorse $7M Carrier Deal Trump Brokered

An Indiana board is poised to endorse a deal directing $7 million in tax breaks and grants for a deal brokered by President Donald Trump to keep hundreds of jobs at the Carrier Corp. factory in Indianapolis.

 

The incentive package is set for a vote by an Indiana Economic Development Board committee on Tuesday, nearly four months after Trump celebrated the deal at the furnace factory.

 

Carrier is pledging to keep nearly 1,100 jobs at the factory, including about 800 production jobs that the company had planned to outsource to Mexico. But about 550 jobs are still being lost. Carrier is also investing $16 million for automation at the factory.

 

Plant union president Chuck Jones says the deal means Indiana taxpayers are rewarding a very profitable corporation for cutting jobs.
