The Czech Republic on Wednesday enforced a smoking ban in bars, restaurants and cafes, putting to an end to the country’s status as one of the last havens for tobacco smokers in Europe.

The ban, which applies to inside areas of bars and restaurants as well as public places like cinemas, theaters and sports venues, was approved by Parliament following years of heated debate and signed by President Milos Zeman, a chain smoker.

Unlike most of Europe, Czechs had remained tolerant of smoking up until now — and it was up to restaurant owners to decide whether to allow it in their establishments.

According to data from the European Union, 17 member states have comprehensive smoke-free laws in place. But some, including Austria, Portugal, Romania and Serbia, only have partial bans on indoor smoking in restaurants and bars.

Others, like Greece, have official bans but the rules are flouted — even by government ministers.

After the Czech ban, Slovakia appeared to be the only EU country left with no official ban in place inside bars.

The Czech Health Ministry said it estimated 18,000 Czechs die of smoking every year and another two thousand non-smokers die due to exposure to second-hand smoke.

From Wednesday, which is World No Tobacco Day, violating the ban would incur a fine of up to 5,000 koruna ($190).

Most Czechs approve the ban, but a group of lawmakers have challenged it at the Constitutional Court.

Jakub Storek, owner of the Cafe Liberal in Prague — a popular hangout among local smokers — said he opposed the ban.

“It’s hard to predict the impact at the moment,” he said. “But I guess it would be different clients coming here in the future.”

Stepan Ourecky said he would still come, but may have a smoke outside the cafe.

“Or perhaps, I will smoke less,” the 18-year-old student said.

Most smokers in China, the world’s largest tobacco consumer, have no intention of kicking the habit and remain unaware of some of its most damaging health effects, Chinese health officials and outside researchers said Wednesday.

An estimated 316 million people smoke in China, almost a quarter of the population, and concerns are growing about the long-term effects on public health and the economy.

The vast majority of smokers are men, of whom 59 percent told surveyors that they have no plans to quit, according to a decade-long study by the Chinese Center for Disease Control and Prevention and Canadian researchers with the International Tobacco Control project.

Such numbers have prompted efforts to restrict the formerly ubiquitous practice. Major cities including Beijing and Shanghai having recently moved to ban public smoking, with Shanghai’s prohibition going into effect in March. In 2015, the central government approved a modest nationwide cigarette tax increase.

But Chinese and international health officials argue that more is needed, including a nationwide public smoking ban, higher cigarette taxes and more aggressive health warnings. Such actions are “critically important,” Yuan Jiang, director of tobacco control for the Chinese Center for Disease Control, said in a statement released with Wednesday’s study.

A public smoking ban appeared imminent last year. The government health ministry said in December that it would happen by the end of 2016, but that has yet to materialize.

“They have to figure out what’s important as a health policy,” said Geoffrey Fong of Canada’s University of Waterloo, one of the authors of Wednesday’s study. “Every third man that you pass on the street in China will die of cigarettes. …When you have cheap cigarettes, people will smoke them.”

In line with global trends, smoking rates among Chinese have fallen slowly over the past 25 years, by about 1 percent annually among men and 2.6 percent among women, according to a separate study published in April in the medical journal The Lancet.

Yet because of China’s population growth — 1.37 billion people at last count — the actual number of smokers has continued to increase. Rising prosperity means cigarettes have become more affordable, while low taxes keep the cost of some brands at less than $1 a pack.

Sixty percent of Chinese smokers were unaware that cigarettes can lead to strokes and almost 40 percent weren’t aware that smoking causes heart disease, according to the study, which was released on World No Tobacco Day, when the World Health Organization and others highlight health risks associated with tobacco use.

Judith Mackay, an anti-tobacco advocate based in Hong Kong, said China has made strides with the public smoking bans in some cities and a similar ban covering schools and universities, but that’s not enough.

“This is the first time there has been a report looking at the overall picture of where China stands,” said Mackay, senior adviser at Vital Strategies, a global health organization. “The reality is, it’s falling behind.”

Mackay blamed behind the scenes lobbying by China’s state-owned tobacco monopoly for impeding efforts to toughen tobacco policies. The State Tobacco Monopoly Administration did not immediately respond to a request for comment.

Government agencies and research institutes in China, Canada and the United States funded the study.

Lowering expectations, Iowa’s two Republican senators say the long-promised repeal of “Obamacare” is unlikely, and any final agreement with the Republican-controlled House is uncertain.

The comments Tuesday by Sens. Chuck Grassley and Joni Ernst come as the Republican-controlled Senate moves forward on its work to dismantle the 2010 health care bill while facing conflicting demands within their own party and lockstep Democratic opposition. Both senators are active players in the health care debate.

“You can’t repeal it in its entirety,” Ernst told reporters after a joint appearance with Grassley in suburban Des Moines.

Frank admission

It was a frank admission from loyal conservatives representing a state Republican Donald Trump carried in November.

The Senate’s filibuster rule means that Republicans — who control the Senate with 52 seats — can’t repeal the entire law.

“You’ve got to have 60 votes and we don’t have 60 votes at this point,” Grassley said.

Grassley, in his seventh term, is a senior member of the Finance Committee, which oversees the law’s tax and Medicaid provisions. Ernst, elected in 2014, says has been part of an informal GOP health care working group’s discussions.

“As much as I’d love to go back and scrap the whole darn thing, we’re simply unable to do that,” Ernst said.

Other Senate rules permit the GOP majority to repeal portions of Obamacare without Democratic support but render other parts of the law off limits.

“That just allows us to tinker around the edges,” Ernst earlier told Eric Borseth, an Altoona, Iowa, businessman who implored her to “get rid of that monstrosity.”

What Grassley and Ernst did not mention are divisions within the Republican caucus in the Senate. Getting every Republican on board is proving arduous.

House measure

House Republicans passed a measure May 4 axing major parts of the 2010 law, including hundreds of billions in extra Medicaid money that 31 states now receive for expanding to cover more lower-income Americans under the federal insurance program.

Such provisions, as well as the nonpartisan Congressional Budget Office’s estimate that 23 million Americans would lose health insurance, make the House bill a non-starter with several Republican senators.

Erasing Obama’s health care law was a top promise of Donald Trump during his presidential campaign, and by congressional GOP candidates since its 2010 enactment.

But writing legislation that can pass with only Republican votes has proven agonizing.

House Speaker Paul Ryan of Wisconsin canceled a March vote after opposition from party conservatives and moderates would have sealed its defeat, and the two wings of the GOP spent weeks blaming each other for the bill’s demise.

Ernst says the Senate will be able to make individual changes to Obama’s law where only a simple majority vote is required.

For instance, she mentioned changing mandatory health care benefits required by insurers as ripe for Senate action.

Ernst stopped short of saying whether any legislation passed in the Senate would be accepted by the House.

“We will be working with the House,” she said.

DNA from mummies found at a site once known for its cult to the Egyptian god of the afterlife is unwrapping intriguing insight into the people of ancient Egypt, including a surprise discovery that they had scant genetic ties to sub-Saharan Africa.

Scientists on Tuesday said they examined genome data from 90 mummies from the Abusir el-Malek archaeological site, located about 70 miles (115 km) south of Cairo, in the most sophisticated genetic study of ancient Egyptians ever conducted.

The DNA was extracted from the teeth and bones of mummies from a vast burial ground associated with the green-skinned god Osiris. The oldest were from about 1388 BC during the New Kingdom, a high point in ancient Egyptian influence and culture.

Genomes provide a surprise

The most recent were from about 426 AD, centuries after Egypt had become a Roman Empire province.

“There has been much discussion about the genetic ancestry of ancient Egyptians,” said archeogeneticist Johannes Krause of the Max Planck Institute for the Science of Human History in Germany, who led the study published in the journal Nature Communications.

“Are modern Egyptians direct descendants of ancient Egyptians? Was there genetic continuity in Egypt through time? Did foreign invaders change the genetic makeup: for example, did Egyptians become more ‘European’ after Alexander the Great conquered Egypt?” Krause added. “Ancient DNA can address those questions.”

The genomes showed that, unlike modern Egyptians, ancient Egyptians had little to no genetic kinship with sub-Saharan populations, some of which like ancient Ethiopia were known to have had significant interactions with Egypt.

The closest genetic ties were to the peoples of the ancient Near East, spanning parts of Iraq and Turkey as well as Israel, Jordan, Syria and Lebanon.

Middle-class mummies

Egypt, located in North Africa at a crossroads of continents in the ancient Mediterranean world, for millennia boasted one of the most advanced civilizations in antiquity, known for military might, wondrous architecture including massive pyramids and imposing temples, art, hieroglyphs and a pantheon of deities.

Mummification was used to preserve the bodies of the dead for the afterlife. The mummies in the study were of middle-class people, not royalty.

The researchers found genetic continuity spanning the New Kingdom and Roman times, with the amount of sub-Saharan ancestry increasing substantially about 700 years ago, for unclear reasons.

“There was no detectable change for those 1,800 years of Egyptian history,” Krause said. “The big change happened between then and now.”

U.N. Secretary-General Antonio Guterres on Tuesday urged the Trump administration not to leave the Paris Climate Agreement, saying the deal would have long-term benefits for the U.S. economy and even its security.

Speaking to an audience of students, civil society and business leaders at New York University, Guterres delivered his subtle pitch to the U.S. administration, which has said a decision about whether to stay in the 2015 agreement will come soon.

“If one country decides not to be present — I’m talking about countries with an important global reach, like it is the case with United States or China — if one country decides to leave a void, I can guarantee someone else will occupy it,” Guterres said in response to a student’s question about dealing with the Trump administration’s skepticism about climate change.

Guterres said he was engaging with the administration and Congress to try to convince them that it is in the United States’ interest to stay in the deal, which seeks to keep the global temperature rise this century well below 2 degrees Celsius.

“There are many good arguments that in my opinion should lead an administration that has a concern to put its own interests first, and the interests of its people and its country first, to invest in what is necessary to preserve the global reach of its economy and to preserve the security of its citizens,” Guterres said, alluding to Trump’s “America First” policy.

“And so my argument today is that it is absolutely essential that the world implements the Paris Agreement, and that we fulfill that duty with increased ambition,” Guterres said during his prepared address.

He said the science was “beyond doubt” and that the effects of global warming already were being felt around the world.

Nearly every country has signed on to the Paris Agreement, and a majority have ratified it. The accord entered into force last November. In addition to lowering greenhouse gas emissions, it seeks to mitigate the effects already felt by global warming.

“The sustainability train has left the station,” Guterres said. “Get on board or get left behind. Those who fail to bet on the green economy will be living in a grey future.”

He praised China for its “massive shift to other forms of energy,” saying the country had made a “very strong bet recently in greening its economy.”

Renewable energy

The U.N. chief noted that renewable forms of energy were growing in use and decreasing in cost.

“Last year, solar power grew 50 percent, with China and the United States in the lead,” he said. “Around the world, over half of the new power generation capacity now comes from renewables. In Europe, the figure is more than 90 percent.”

He said 80 percent of the world’s energy still comes from fossil fuels — oil, gas and coal — and that would not change overnight. But it is important, he said, to engage the energy industry and governments to use those energy sources as moderately as possible while making the transition to renewable, clean ones.

“I think they are working towards having an answer for that, and so we’ll wait and see what that answer is,” Nikki Haley, the U.S. ambassador to the U.N., told reporters earlier Tuesday when asked about the administration’s plans.

The World Health Organization warns that more than 7 million people die prematurely every year from tobacco-related causes, and it’s a costly drain on national economies.

In advance of World No Tobacco day, to be observed Wednesday, the global health agency urged governments to implement strong tobacco control measures for the health of their people and their economies.

WHO calls tobacco a threat to development. Besides the heavy toll in lives lost, global estimates show that “tobacco costs the global economy $1.4 trillion a year,” or 1.8 percent of global gross domestic product. The WHO notes this estimate takes into consideration “only medical expenses and lost productive capacities.”

Despite effective tobacco control measures, WHO reports the number of people dying from smoking is increasing because those dying today have mostly been long-term smokers and it takes time for tobacco control policies to make an impact.

Vinayak Prasad, program manager of the WHO’s Tobacco Free Initiative, told VOA, “What we are seeing is that if the policies were not in place, the number of 7.2 million would have been higher. We are seeing a reduction of tobacco use prevalence in most countries. The only regions now which are seeing higher growth are the African continent and Middle Eastern region. The rest of the world is seeing a decline.”

Diseases, disabilities

Besides leading to premature death, the WHO has found, countless millions of people who smoke suffer from a wide variety of tobacco-related diseases and resultant serious disabilities, including blindness, amputation, impotence and poor oral health.

Andrew Black of the WHO Framework Convention on Tobacco Control Secretariat noted that smoking is an addiction largely taken up in childhood and adolescence, “so it is crucial to reduce the number of young people taking up smoking in the first place. We must stop the tobacco industry’s powerful advertising and promotion, which can all too often be oriented toward young people.”

Black said tobacco widens social inequalities and is a driver of poverty around the world.

“We know that those living on lower incomes in virtually all countries are likely to smoke, and therefore more likely to suffer the consequences of tobacco use,” he said.

Black said that by 2030, about 80 percent of the world’s tobacco-related mortality will be in low- and middle-income countries.

“High rates of tobacco use being promoted by aggressive strategies from the tobacco industry are projected to lead to a doubling of the number of tobacco-related deaths in low- and middle-income countries between 2010 and 2030,” he said.

Study issued

To mark World No-Tobacco Day, the U.N. Development Program and the Secretariat of the WHO Framework Convention on Tobacco Control issued a study that focuses on the harmful effects of tobacco on both health and on efforts aimed at achieving the U.N.’s sustainable development goals (SDGs).

Dudley Tarlton, UNDP program specialist on health and development, told VOA that tobacco undermines the SDGs because “household consumption on tobacco displaces consumption on other goods and services that might lead to a better end.

“So, it affects poverty. It affects hunger. Education is affected. Children get ear infections because they are exposed to household smoke in the home,” he said.

For the first time, the WHO and UNDP released a joint report showing the bad impact tobacco has on the environment.

Prasad acknowledged that the data received from the tobacco industry and from governments were relatively weak. Nevertheless, he said, “the evidence is really astounding as to how tobacco is extremely dangerous and harming the environment.”

He said using land to grow tobacco “can lead to severe damage because of the widespread use of agrochemicals.”

Use of trees

Prasad noted that more than 11 million metric tons of wood was required to cure and dry tobacco, “which essentially means deforestation is already happening.”

The report found that tobacco waste contains over 7,000 toxic chemicals that poison the environment, including human carcinogens, and that tobacco smoke contributes “thousands of tons of human carcinogens, toxicants and greenhouse gases to the environment.”

Prasad said that cigarettes are bad news for tree lovers because “for every 300 cigarettes, we need to cut a tree. … Even conservatively, if we are looking at 6 trillion cigarettes, we are looking at almost 15 to 20 billion trees to cut.

“We have 6 trillion trees in the world, so we are almost looking at a big cut, which is going to happen, if we do not hold this,” he said.

And regarding the sullying of the world’s environment, he noted that cigarette butts “account for 30 to 40 percent of all items collected in coastal and urban cleanups.”

Scientists have tweaked a powerful antibiotic, called vancomycin, so it is once more powerful against life-threatening bacterial infections.  Researchers say the more powerful compound could eliminate the threat of antibiotic resistance for many years to come.

Antibiotic resistance, in which microbes no longer respond to drugs, is quickly becoming a global health emergency.  Of particular concern are so-called “superbugs,” a handful of pathogens that patients acquire in hospitals and other health care settings.  Patients recovering from surgery are particularly vulnerable to the resistant, hospital-borne infections, which put them at high risk of death.  

Researchers at The Scripps Research Institute in La Jolla, California, modified vancomycin, invented 60 years ago and considered a last resort treatment against many of these infections.   They made a key change to its molecular structure, interfering with how the bacterium, enterococcus, makes protective cells walls.

In a new study published in the journal Proceedings of the National Academy of Sciences, investigators describe how the change made vancomycin 1,000 times more effective against both drug-resistant enterococci and the original forms of the microorganism.

‘Total cures’

The modification is in addition to two previous changes made by the Scripps team that improved the drug’s potency, so less of it is needed to treat an infection.  

Lead researcher Dale Boger, who co-chairs the institution’s Department of Chemistry, said it is difficult for enterococcus to find a way around three independent mechanisms of action.  “Even if they found a solution to one of those,” said Boger, “the organisms would still be killed by the other two.”

The challenge now for researchers is to reduce the number of steps it takes in the lab to boost vancomycin’s effectiveness.  Having redesigned the antibiotic’s molecular structure, Boger called streamlining its production the “easy part.”

Even if researchers are unable to simplify the way the improvements are made, Boger said efforts to supercharge vancomycin are worth it for the antibiotic’s lifesaving powers, calling the drugs “total cures” against bacterial infection.

Given the growing failure of antibiotics to treat common infections, Boger said making the super-charged vancomycin molecule is important, even if it’s labor-intensive.

Democratic Republic of Congo’s Health Ministry has approved the use of a new Ebola vaccine to counter an outbreak of the hemorrhagic fever in its northeast that has killed four people, a spokesman said on Monday.

“The non-objection was given. Now there’s a Medecins Sans Frontieres team that is arriving [in Congo] today to validate the protocol with the technical teams,” Jonathan Simba, a Health Ministry spokesman, said by telephone.

The vaccine, known as rVSV-ZEBOV and developed by Merck, is not yet licensed but was shown to be highly protective against Ebola in clinical trials published last December.

As of Friday, Congo had registered 52 total suspected cases, including two that have been confirmed, the World Health Organization spokesman in Congo, Eugene Kabambi, said by telephone, adding that the situation appears to be under control.

Simba said that the details of the vaccination campaign would be announced after a meeting of the health ministry and its partners set to take place on Monday or Tuesday.

A vaccination campaign would present logistical challenges in Congo’s isolated northeastern forests, including transporting and storing the vaccine in special containers at the required minus 80 degrees Celsius.

Scientists are helping to combat the world hunger crisis by breeding nutrient-packed crops that will fill stomachs and lessen the effects of malnutrition.

It’s called biofortification.

It sounds complicated, but the concept is simple: create smarter seeds that grow into more nutrient-dense staple crops than regular ones. Then distribute the seeds on a large scale to farmers in developing countries, so they can grow crops that are more nutritious.

Seeds with more nutrients

This is what researchers at HarvestPlus, a Washington-based nonprofit, have been doing on a large scale since 2003, feeding an estimated 20 million people in 30 countries.

Their biofortified seeds pack one or more vital nutrients, such as iron, zinc and Vitamin A, said Bev Postma, HarvestPlus’ CEO.

“It’s very important that the seeds are not just high in nutrition, but that they are still high-yielding, they are pest resistant, they are climate resistant — because these are the things a farmer still wants more,” she said.

Deficiencies of these nutrients can leave people more vulnerable to illness and infections, and in extreme cases cause blindness and stunt growth. Children are especially affected.

The organization’s research has found that many of these effects can be reversed in a matter of months once nutrient-packed foods are introduced into the local diet.

150 varieties of 12 staples

HarvestPlus scientists have produced 150 varieties of 12 staple foods, including corn, beans, rice, lentils and wheat.

In 2003, the Bill and Melinda Gates Foundation gave the organization a $25 million grant over four years to help them scale up. This year, they are one of eight finalists for a $100 million grant from the MacArthur Foundation, which could help them realize their goal of reaching 1 billion people with biofortified crops by 2030.

“We’re not trying to change behavior, we are looking to see what people are eating and we are just switching out to make that food more nutritious,” Postma said.

Biofortified seeds are produced in a traditional manner, and they are not genetically modified.

Seed distribution

The seeds are distributed through seed companies and sometimes directly to farmers.

“We’ve learned that in some countries, if we give the seed away, we can encourage the farmers to not just grow this new variety, but then ask them to give the next year’s seed that they harvest to four new farmers,” Postma said.

In other instances, she said, they work with seed companies to persuade them to adopt biofortified seeds and sell them as part of a package of options to farmers.

“We find in some instances it is better if farmers are paying for these seeds, because then there is a perceived value and adoption is higher,” she said. Postma said they try to make sure that their seeds are not more expensive than regular varieties.

The organization works with government agriculture and health ministries in developing countries to encourage them to adopt biofortified seeds as a cost-effective way to solve some of their major health problems.

People with a common cluster of symptoms that puts them at increased risk of heart disease and diabetes are two times as likely to die as people without those risk factors if they get less than six hours of sleep per night.

That was the finding of a new study conducted by researchers at Pennsylvania State College of Medicine and reported in the Journal of the American Heart Association.

So-called metabolic syndrome is marked by elevated blood sugar, high blood pressure and cholesterol, and excess fat around the waistline. A diagnosis of metabolic syndrome also includes a high body mass index (BMI), a measurement of a person’s weight relative to his height.  

People with a high BMI and other symptoms of metabolic syndrome are at increased risk of developing heart disease and diabetes.

Study participants

In the study, a group of 1,344 adults agreed to spend one night in a sleep clinic. Almost 40 percent of the participants were found to have at least three of the risk factors of metabolic syndrome.

When the participants were followed up an average of 16 years later, 22 percent of them had died.

Compared with those without metabolic syndrome, investigators found those with a cluster of heart disease and diabetes risk factors were 2.1 times more likely to have died of stroke if they slept less than six hours during their night in the lab.

If they had slept more than six hours, those with metabolic syndrome were about 1½ times more likely to have suffered a fatal stroke than normal participants.

Finally, those with metabolic syndrome who slept less than six hours were almost two times more likely to have died of any cause compared with those without the heart disease and diabetes risk factors.

The study is the first to examine the impact of sleep duration on the risk of death in patients with metabolic syndrome.

More trials planned

If you have metabolic syndrome, the study’s authors note it is important to notify your doctor if you are not getting enough sleep to reduce the risk of death from heart attack or stroke.

The researchers plan future clinical trials to determine whether increasing the length of quality sleep, in addition to lowering blood pressure and glucose, improves the prognosis for people with metabolic syndrome.

The American Heart Association recently issued a scientific statement noting that an increasing number of Americans suffer from sleep difficulties, either involuntarily or because they’d rather stay up late, and this trend may be associated with increased cardiovascular risks and outcomes.

Construction began in Chile on Friday on the European Extremely Large Telescope, which when completed will be the world’s largest optical telescope, some five times larger than the top observing instruments in use today.

The size of the ELT has the potential to transform our understanding of the universe, say its backers, with its main mirror that will measure some 39 meters (43 yards) across.

Located on a 3,000 meter-high mountain (9,800 feet) in the middle of the Atacama desert, it is due to begin operating in 2024.

Spark the spotting of more planets

Among other capabilities, it will add to and refine astronomers’ burgeoning discoveries of planets orbiting other stars, with the ability to find more smaller planets, image larger ones, and possibly characterize their atmospheres, a key step in understanding if life is present.

“What is being raised here is more than a telescope. Here we see one of the greatest examples of the possibilities of science,” said Chilean President Michelle Bachelet in a speech to mark the beginning of construction at the site.

Dry air makes for near perfect conditions

The dry atmosphere of the Atacama provides as near perfect observing conditions as it is possible to find on Earth, with some 70 percent of the world’s astronomical infrastructure slated to be located in the region by the 2020s.

The ELT is being funded by the European Southern Observatory, an organization consisting of European and southern hemisphere nations. Construction costs were not available but the ESO has said previously that the ELT would cost around 1 billion euros ($1.12 billion) at 2012 prices.

Tests are underway to determine the genetic sequence of the Ebola virus behind an outbreak in central Africa, a U.S. Centers for Disease Control researcher said Friday.

Dr. Barbara Knust, an epidemiologist, told VOA’s Horn of Africa service that scientists are looking for “clues” about where this strain of Ebola originated and how to treat it.

“That could help [us] understand how this virus is related to other viruses that have caused other Ebola outbreaks,” she said.

The latest Ebola outbreak is in northern Democratic Republic of the Congo, in a remote area near the border with the Central African Republic.  The World Health Organization said that as of May 24, Ebola had killed four people in the area and the number of suspected cases stood at 44.

The Ebola virus, which causes a type of hemorrhagic fever, killed more than 11,000 people across the West African countries of Guinea, Liberia and Sierra Leone in 2014 and 2015.  

Resources ‘mobilized quickly’

Staff from the CDC, the WHO, the Congolese Ministry of Health and other agencies are in Congo’s Bas Uele province, working to contain the spread of the virus. Knust said the international response was going “fine.”  

“The responders involved in this outbreak very certainly are taking it seriously and the resources have been mobilized quickly,” she said. “At least at this point of time [it] appears that it was detected fairly early, although that information is forthcoming. There is some hope it will remain a limited outbreak.”

She said there had been discussion of using experimental treatments used in the West African outbreak, but that the Congolese government had not given its approval.

Dr. Galma Guyo, a disease control specialist in Nairobi, was part of an African Union team that responded to the Ebola outbreak in Liberia.  He warned that the DRC’s location in the center of Africa could allow the virus there to spread across borders.

“There is a possibility that the viruses can easily spread and be hard to detect due to the remoteness of the region, too,” he said.

There’s a glimmer of hope for the American bee population. But, according to a new study, the outlook for this critical insect is mostly grim. Researchers report a slowing of the rate of decline in the bee population over the past year, dropping to its lowest since 2011-2012.

But, both commercial and small-scale beekeepers lost 33 percent of their honey bee colonies between April 2016 and April 2017.

“While it is encouraging that losses are lower than in the past, I would stop short of calling this ‘good’ news,” said Dennis van Engelsdorp, an assistant professor of entomology at the University of Maryland and project director for the Bee Informed Partnership, in a summary of the study.

“Colony loss of more than 30 percent over the entire year is high,” he added. “It’s hard to imagine any other agricultural sector being able to stay in business with such consistently high losses.”

Researchers point to many causes for the drop in bee populations, with parasites, particularly the varroa mite, and other diseases as the main culprits. Pesticides are also a factor, according to the study, particularly among commercial beekeepers. The researchers describes like a kind of synergy among all the causes that amount to worsening each individual problem.

“This is a complex problem,” said Kelly Kulhanek, a graduate student in the UMD Department of Entomology who helped with the survey. “Lower losses are a great start, but it’s important to remember that 33 percent is still much higher than beekeepers deem acceptable. There is still much work to do.”

The annual survey, which has been conducted for 11 years, aims to find why bee colonies are suffering, a problem that can have big consequences for human beings, given that honey bees pollinate $15 billion worth of U.S. agriculture annually. Almonds, researchers say are a perfect example: their growth is entirely dependent on bees for pollination.

“Bees are good indicators of the health of the landscape as a whole,” said Nathalie Steinhauer, a graduate student in the UMD Department of Entomology who leads the data collection efforts for the annual survey. “Honey bees are strongly affected by the quality of their environment, including flower diversity, contaminants and pests….Honey bee health is a community matter.”

Scientists looking at the first pictures of the planet Jupiter sent by the NASA probe Juno were shocked at what they saw: monster cyclones, hundreds of kilometers wide, tearing across the planet’s north and south poles.

The scientists said the poles are nothing like the planet’s familiar placid and colorful equatorial region.

“That’s the Jupiter we’ve all known and grown to love,” Scott Bolton of the Southwest Research Institute, an applied research and development organization in San Antonio, Texas, said in an article released Thursday in the journal Science.  “And when you look from the pole, it looks totally different. … I don’t think anybody would have guessed this is Jupiter.”

Bolton called the findings “Earth-shattering. Or, should I say, Jupiter-shattering.”

Along with the fierce storms, the researchers saw a huge river of ammonia gas extending from Jupiter’s deep atmosphere down to its interior. They said they thought the ammonia might be part of what’s causing the huge storms.

NASA launched Juno in 2011, and it reached Jupiter’s orbit last year. The scientists said Juno’s next fly-by would come in July, when it will take pictures of the planet’s trademark Great Red Spot — a huge, hurricane-like storm that experts say has been raging for hundreds of years.

The next generation hypersonic space plane just took a big step toward reality as the Defense Advanced Research Projects Agency (DARPA) announced Boeing will “complete advanced design work” for the Experimental Spaceplane, XS-1.

The goal of the project is to offer quicker access to low Earth orbit, decreasing the preparation time to launch from months to days. For example, in the case of the loss of a military or commercial satellite, the unmanned, reusable XS-1 could quickly be used to launch a replacement.

“The XS-1 would be neither a traditional airplane nor a conventional launch vehicle, but rather a combination of the two, with the goal of lowering launch costs by a factor of 10 and replacing today’s frustratingly long wait time with launch on demand,” said Jess Sponable, DARPA program manager.

According to DARPA, the XS-1 will be about the size of a business jet and take off vertically, propelled not by external boosters but by “self contained cryogenic propellants.” After reaching a suborbital altitude, the plane would launch an expendable upper stage that would be able to push a satellite into orbit. The plane would then return to Earth, landing like a plane.

DARPA said the plane could then be reused “potentially within hours.”

The XS-1 could fly as fast as Mach 10, DARPA said.

The XS-1 is still years away from reality, with DARPA saying testing the plane’s engines on the ground slated for 2019.

Tony Chhim, a first-generation Cambodian-American, needs a kidney.

Until a few weeks ago, his family thought a yearlong search among relatives in Cambodia and in Khmer communities throughout the United States had been fruitless. Then Taylor Tagg, an American friend of Tony’s dad, Tim, surprised everyone by turning out to be a match.

The euphoria lasted until a few days ago, when doctors at the Westchester Medical Center in Valhalla, New York, discovered a complication. That dashed what had been a feel-good, one-in-a-million, happy-ending kind of saga that transcended race, religion and national origin, as Tagg prepared to be the first American to donate a kidney to the son of Cambodian refugees.

Painful dialysis 3 times a week

Tony Chhim, 31, is Tim’s only son. Born in the United States, Tony is a football player and roots for the North Rockland Red Raiders football team in Thiells, New York. With only one functioning kidney, he’s in dialysis.

“It’s painful. Imagine you go [for treatment] four to five hours every other day for the rest of your life,” Tony said. “How much of that is your life?”

Now, once again, Taylor Tagg and Tim Chhim are supporting Tony during another search for a kidney match. Julie Kimbrough, senior director of marketing and communications for the National Kidney Foundation, told VOA Khmer the numbers are grim: About 19,000 people receive a transplant every year, and there are 120,000 people waiting for a kidney transplant.

“Every year there are over 4,000 people who die waiting” for help, she said.

A ‘special’ connection

Tagg and the older Chhim met in 2012 when they joined the same self-help group. A shared history of overcoming the kind of life trials that would stop many others — Tim escaped execution by the Khmer Rouge three times — grew into a friendship and a business partnership.

Neither of them cared that Tagg is a white Christian American and Chhim is an Asian Buddhist immigrant.

Tagg, a life coach who teaches forgiveness, lives in Germantown, Tennessee. The 46-year-old’s motto is: “Life gets better when you let go of the bitters.”

Chhim owns an Allstate Insurance agency in Nanuet, New York, and also is a motivational speaker.

His positive message dovetails with Tagg’s message of self-empowerment to survivors, especially refugees: “Don’t become victims forever. You were a victim, but not now. Now you are a victor.”

Tagg says they have a “special” connection.

In 2015, the two men co-wrote a book, Adversity to Advantage: 3 Epic Stories of Transforming Life’s Obstacles into Opportunity.

A hero’s gift

“We both felt through our meeting through the Napoleon Hill Foundation,  then writing a book together, a higher power placed us in our paths so that we can come together for Tony’s needs to help him with his kidney,” Tagg said. “Tim is one of my living heroes, and so when the opportunity presented itself, he asked for a blood test. Those with O blood type stepped up to get tested. Of course, I did that and turned out to be a match for Tony.”

Chhim has the same feeling about Tagg: “Taylor, you are my hero, not the other way around. How many people out there are willing to give a part of their body, their organ for someone else who’s not related to you?”

Not many. But Neang Chhim, 59, Tony’s mother, understands this sacrifice. In 2010, she gave one of her kidneys to her son.

“You have to do what a mother has to do,” she said. “I checked the blood and it matched. You act quickly because you try to save your son’s life.”

Five years later, Tony’s body rejected Neang’s kidney, and that led to the tests that showed Tagg’s kidney was a match for the young man’s.

Tony says that kindness transcends any differences: “For me, it doesn’t matter if you’re non-Cambodian, black, and white. Just the fact that anybody that would step up that didn’t even know me, it really touched me. It made me happy inside knowing that there are people out there that do genuinely want to help.”

The kidney transplant surgery was scheduled for this week, but three weeks ago the medical team called it off because of complications that indicated it would not be a long-term solution to Tony’s problems.

Tony Chhim says his bond with Taylor Tagg is solid: “I still consider him my brother and he’s just as heartbroken as I am.”

Ever his father’s son, Tony vows to keep on fighting, “to find the good in the adversity.” And he hopes his story will inspire more organ donors.

“My main mission is to get people aware,” he said. “If one person besides me gets a kidney because I’m talking about it, then I’m more than happy just to stay on dialysis.”

A new study suggests that probiotics, so-called “good” bacteria that aid in digestion, may also ease symptoms of depression. The finding adds to a growing body of evidence that what happens in the gut affects the brain. 

Some 300 to 500 bacterial species inhabit the human gut, many aiding in digestion and the proper functioning of the gastrointestinal tract.

Experts say some of these bacteria produce proteins that communicate with the brain. 

Your gut, your mood

The gut flora not only play a role in helping to orchestrate the neural responses that regulate digestion, scientists say, but evidence is emerging that gut bacteria can also affect a person’s mood.

Premysl Bercik, a gastroenterologist at Ontario Canada’s McMaster University, researches what he calls the microbiota-gut-brain axis, or the communication between the gut and the brain through the millions of bacteria that live in the gastrointestinal tract.

Bercik said between 40 and 90 percent of people with irritable bowel syndrome, a distressing intestinal disorder, also battle symptoms of anxiety and depression.

Research led by Bercik suggests the gut bacteria themselves may have an effect on mood.

In Bercik’s pilot study of 44 patients with irritable bowel syndrome and mild to moderate anxiety or depression, half of the patients received a daily probiotic — a beneficial gut bacterium called Bifidobacterium longum — and the other half were given a placebo. The participants were followed for 10 weeks.

“What we found was that the patients that were treated with this probiotic bacterium improved their gut symptoms but, also surprisingly, decreased their depression scores,” Bercik said. “That means their mood improved. And this was associated also with changes in the brain imaging.”

Depression, anxiety improve

At the beginning of the study, the patients’ levels of depression and anxiety were scored. The patients also underwent high-tech brain imaging to see which structures were activated in response to happy and sad images.

At six weeks, 64 percent of patients taking the probiotic had a decrease in their depression scores compared to 32 percent of the placebo patients. 

A second round of imaging showed changes in multiple brain areas involved with mood control in the patients who felt better. 

While the participants’ gut symptoms improved, Bercik said it was not to a statistically significant degree, suggesting the probiotic may have improved their anxiety and depression independent of symptom relief.

Results of the study were published in the journal Gastroenterology.

More study needed

Bercik says larger studies are needed to confirm the findings.

“However, I think that it shows a great promise,” he said. “I mean new treatments, not only for patients with functional bowel disorders like irritable bowel syndrome, but it may also offer some new treatments for patients with primary psychiatric disorders like depression or anxiety.”

B. longum was developed by Nestle, a Swiss food and drink company, which funded the study. It is not yet commercially available. 

However, Bercik says it’s possible other probiotics found in the gut have the potential to improve mood. And he doesn’t stop there. Bercik says he envisions a form of personalized medicine using genome sequencing techniques to create microbiome profiles of individuals, which can be tweaked with oral probiotics for maximum health.

Tedros Adhanom Ghebreyesus, the World Health Organization’s newly elected director-general, says health as a human right is at the core of his vision for the organization he soon will lead.

The former Ethiopian health and foreign minister is the first African chosen to head the organization, which was created 69 years ago.  

After a long, bruising campaign that began in 2015, Tedros beat out two other contenders, David Nabarro of Britain and Pakistani physician Sania Nishtar, for the post by winning 133 of the votes cast by 185 WHO member states.

“The outcome of the voting was very, very clear,” said Tedros.  “Having confidence from the majority of member states gives me legitimacy to really implement the vision that I have already outlined.”

Tedros’ goals

That vision included five promises, which Tedros made to the World Health Assembly during a final campaign pitch preceding Tuesday’s secret ballot vote.

He said that he would “work tirelessly” to fulfill the WHO promise of universal coverage and would ensure “a robust response for emergencies to come.”

He promised to strengthen the frontlines of health, transform the World Health Organization into a world class force and lastly “place accountability, transparency and continuous improvement at the heart of WHOs culture.”

At a news conference in Geneva, he said the concept of health as a human right would be at the heart of whatever he did.

“Half of our population does not have access to health care,” he said.  That, he said, could and should be remedied through universal health care coverage, which would address the issue of health as a human right and act as a spur to development.  

“All roads should lead to universal health coverage and it should be the center of gravity of our movement,” he said.  

Tedros begins his five-year term as director-general on July 1, succeeding Margaret Chan, who has headed the WHO for the past 10 years.  

The newly elected director general said he wants to reform and transform the World Health Organization into a better, more responsive agency.    

As Ethiopia’s minister of health, Tedros led a comprehensive reform of the country’s health system, including the expansion of the country’s health infrastructure and health insurance coverage.

Resources a constant priority

As WHO leader, Tedros said one of his first orders of business would be to strengthen the organization’s ability to respond swiftly and effectively to emergencies because “epidemics can strike at any time” and the WHO must be prepared.

“The campaign has ended, as you know, officially, but I think the work begins actually now.  I know it is very difficult.  It is going to be tough,” he said.  

One of the major difficulties is that of money.  Reform, tackling emerging and ancient diseases take a lot of money, something the World Health Organization, which reportedly is struggling to close a $2.2 billion gap, does not have.

The problem is likely to be made even worse given the Trump administration announced budget cuts to global health programs, including a 32 percent cut to USAID (U.S. Agency for International Development) and between 20 percent and 30 percent cuts for scientific research institutes.

The United States is the biggest WHO donor.  U.S. President Donald Trump has suggested funding cuts to the organization might be in the offing.

Tedros observed that it is the poor that are the most affected by big financial cuts.

“I hope this will be understood before finalizing the proposal.  I believe this will be taken into consideration,” he said.

He can take heart in that a congratulatory statement on his election from Tim Price, U.S. Health and Human Services Secretary did not threaten any funding cuts.  Instead, he told Tedros the United States looked forward to working with him on changing the World Health Organization for the better.

“The United States is committed to helping advance reforms and cultivating greater global health security,” he said.
