Recent studies suggest that as many as 400 million people around the world do not have access to basic health care. In some cases it’s because of conflict, but in some cases it’s just geography: humans live in some very far away places, Siberia for instance. That’s where the medical ship comes in handy.

Health ministers of the G20 leading economies, meeting for the first time Saturday, agreed to work together to tackle issues such as a growing resistance to antibiotics and to start implementing national action plans by the end of 2018.

Germany, which holds the G20 presidency this year, said it was an “important breakthrough” that all nations had agreed to address the problem and work toward obligatory prescriptions for antibiotics.

Pandemics

Saying that globalization caused infectious diseases to spread more quickly than previously, the 20 nations also pledged to strengthen health systems and improve their ability to react to pandemics and other health risks.

“By putting global health on the agenda of the G20 we affirm our role in strengthening the political support for existing initiatives and working to address the economic aspects of global health issues,” the communique said.

The results of the meeting will feed into a G20 leaders’ summit in Hamburg in July.

Overprescription

While the discovery of antibiotics has provided cures for many bacterial infections that had previously been lethal, overprescription has led to the evolution of resistance strains of many bacteria.

An EU report last year found that newly resistant strains of bacteria were responsible for more than 25,000 deaths a year in the 28-member bloc alone.

Germany has argued that even having a discussion about it will help raise public awareness about the problem. The G20 also said they agreed to help improve access to affordable medicine in poorer countries.

A warmer, wetter climate is helping push dozens of Eastern U.S. trees to the north and, surprisingly, west, a new study finds.

The eastern white pine is going west, more than 80 miles (130 kilometers) since the early 1980s. The eastern cottonwood has been heading 77 miles north (124 kilometers), according to the research based on about three decades of forest data.

The northward shift to get to cooler weather was expected, but lead author Songlin Fei of Purdue University and several outside experts were surprised by the move to the west, which was larger and in a majority of the species.

New trees tend to sprout farther north and west while the trees that are farther south and east tend to die off, shifting the geographic center of where trees live. 

86 tree species

Detailed observations of 86 tree species showed, in general, the concentrations of eastern U.S. tree species have shifted more than 25 miles west (45 kilometers) and 20 miles (33 kilometers) north, the researchers reported in the journal Science Advances Wednesday.

One of the more striking examples is the scarlet oak, which in nearly three decades has moved more than 127 miles (205 kilometers) to the northwest from the Appalachians, he said. Now it’s reduced in the Southeast and more popular in the Midwest.

“This analysis provides solid evidence that changes are occurring,” former U.S. Forest Chief Michael Dombeck said in an email. “It’s critical that we not ignore what analyses like these and what science is telling us about what is happening in nature.”

Dryer South, wetter West

The westward movement helped point to climate change, especially wetter weather, as the biggest of many culprits behind the shift, Fei said. The researchers did factor in people cutting down trees and changes to what trees are planted and where, he said.

With the Southeast generally drying and the West getting wetter, that explanation makes some sense, but not completely, said Brent Sohngen at Ohio State University, who was not involved in the study.

“There is no doubt some signature of climate change,” he said in an email. But given the rapid rates of change reported, harvesting, forest fires and other disturbances, are probably still playing a more significant role than climate change, he wrote.

Norway is repairing the entrance of a “doomsday” seed vault on an Arctic island after an unexpected thaw of permafrost let water into a building meant as a deep freeze to safeguard the world’s food supplies.

The water, limited to the 15-meter (50-foot) entrance hall in the melt late last year, had no impact on millions of seeds of crops including rice, maize, potatoes and wheat that are stored more than 110 meters inside the mountainside.

Still, water was an unexpected problem for the vault on the Svalbard archipelago, about 1,000 kilometers (620 miles) from the North Pole. It seeks to safeguard seeds from cataclysms such as nuclear war or disease in natural permafrost.

“Svalbard Global Seed Vault is facing technical improvements in connection with water intrusion,” Norwegian state construction group Statsbygg, which built the vault that opened in 2008, said in a statement on Saturday. “The seeds in the seed vault have never been threatened.”

Spokeswoman Hege Njaa Aschim said Statsbygg had removed electrical equipment from the entrance — a source of heat — and was building waterproof walls inside and ditches outside to channel away any water.

The number of visitors would be reduced to limit human body heat, she said. Some of the water that flowed in re-froze and had to be chipped out by workers from the local fire service.

An underlying problem was that permafrost around the entrance of the vault, which had thawed from the heat of construction a decade ago, has not re-frozen as predicted by scientists, Aschim said.

Temperatures in the Arctic region have been rising at twice the global average in a quickening trend that climate scientists blame on man-made greenhouse gases. Svalbard has sometimes had rain even in the depths of winter when the sun does not rise.

“There’s no doubt that the permafrost will remain in the mountainside where the seeds are,” said Marie Haga, head of the Bonn-based Crop Trust that works with Norway to run the vault. “But we had not expected it to melt around the tunnel.”

Haga said the trust had so far raised just over $200 million toward an $850 million endowment fund to help safeguard seeds in collections around the globe. “That is an extremely cheap insurance policy for the world,” she said.

One of the coldest areas in the world is getting greener, and researchers say it’s because of global warming.

Researchers from the University of Exeter in England who first studied the increase of moss and microbes in the Antarctic Peninsula in 2013, now say the greening of the region is widespread.

“This gives us a much clearer idea of the scale over which these changes are occurring,” says lead author Matthew Amesbury of the University of Exeter.

“Previously, we had only identified such a response in a single location at the far south of the Antarctic Peninsula, but now we know that moss banks are responding to recent climate change across the whole of the Peninsula.”

The peninsula, researchers say, is one of the more rapidly warming area in the world, adding that temperatures have risen by about a half-degree Celsius each decade since the 1950s.

For their study, researchers looked at five more core samples from three areas of moss banks over 150 years old. The new samples included three Antarctic Islands off the peninsula.

The cores, researchers say, showed “increased biological activity” over the past 50 years as the peninsula warmed. Researchers say their findings show “fundamental and widespread change,” and that the change was “striking.”

The changes are likely to continue.

“Temperature increases over roughly the past half-century on the Antarctic Peninsula have had a dramatic effect on moss banks growing in the region, with rapid increases in growth rates and microbial activity,” says Dan Charman, who led the research. “If this continues, and with increasing amounts of ice-free land from continued glacier retreat, the Antarctic Peninsula will be a much greener place in the future.”

The next step for researchers is to look back even further in history to see how climate change affected the region before humans made an impact.

The findings appeared in Current Biology on May 18.

Mozambique has declared an end to a cholera epidemic that was triggered by heavy rains and infected more than 2,000 people, a senior government official said Friday.

The outbreak was another setback for Mozambique, which is grappling with a financial crisis as it strives to woo investors to develop huge offshore gas reserves.

“The epidemic is under control: In the last 28 to 29 days, we have not registered new cases of cholera and so we are declaring the epidemic terminated,” Francisco Mbofana, national director of public health, told a news conference.

Five cholera treatment centers installed in the most affected provinces have already been dismantled, Mbofana said.

Four people died between Jan. 5 and April 22 out of the 2,131 cases registered by health authorities. Last year, in the same period, 103 people died of cholera across the country.

Cholera causes severe vomiting and diarrhea and is often lethal if not treated swiftly.

Yemen could see as many as 250,000 new cases of cholera within six months, in addition to 50,000 already reported, the World Health Organization said Friday.

“The speed of the resurgence of this cholera epidemic is unprecedented,” Nevio Zagaria, WHO country representative for Yemen, told reporters during a conference call on Friday.

He said the death toll from the outbreak has already reached 240 and more than 50,000 cases have been registered in the past three weeks.

Two years into a war between Houthi rebels and government forces allied with a Saudi-led Arab military coalition, which has killed more than 8,000 people, Yemen has declared a state of emergency Sunday in the capital, Sana’a, over the outbreak.

Fighting has taken a toll on medical facilities in the war-torn country, as more than half of Yemen’s facilities, which are now operated by Houthi rebels, no longer function.

The U.N. says some 17 million of Yemen’s 26 million people lack sufficient food and at least three million malnourished children are in “grave peril.”

Yemen, which is the Arab world’s poorest nation, is now classified by the World Health Organization as a level three emergency, alongside Syria, South Sudan, Nigeria and Iraq. This is the country’s second cholera outbreak in less than a year.

Cholera is highly contagious and can be contracted from ingesting contaminated food and water.

The World Health Organization has delivered dramatic news about the causes of death for young people the world over. Governments and health agencies have made great strides in reducing deaths of young children through immunization and programs that address maternal and infant care. But adolescents have somehow fallen through the cracks.

Dr. Anthony Costello, director of WHO’s Department of Maternal, Newborn, Child and Adolescent Health told VOA, “We’re finding 1.2 million (adolescents) die each year. That’s 3,000 deaths a day. That’s 10 jumbo jets.” What’s more, Costello says these deaths are largely preventable.

The study shows traffic injuries are the top cause of death among adolescents, those between 10 and 19. In most cases, the adolescent is struck by a car while walking or riding a bicycle.

Other leading causes of death include lower respiratory infections and suicide, the report found. The causes differ by gender, age and region. Boys between 15 and 19 years old are more likely to die from traffic injuries than girls or than younger boys. In sub-Saharan Africa, children are more likely to contract HIV.   

Girls between 10 and 14 are at risk for getting respiratory infections from indoor air pollution and from breathing in fumes from cooking fuels. Older girls, between 15 and 19, had a greater risk of death from pregnancy complications, childbirth or unsafe abortions. Teenage girls generally have small pelvises which lead to difficult labor.  

Costello said pregnant adolescent girls are also “more likely to get high blood pressure; they may be more vulnerable to bleeding, they may be more anemic. They may be in situations more vulnerable to malaria, to HIV.”  

The point of the study that was conducted by the WHO and partners at other U.N. agencies and the World Bank.

Looking forward

While the study focuses on the causes of death, Costello said the point was to help develop a framework and a plan to improve the health of adolescents. If adolescents had access to good health services, education and social support, fewer young people would die. In the case of traffic related deaths, he said better traffic laws, speed limits, the use of seatbelts could save lives in countries that don’t have strict driving safety laws. Costello pointed out that “In India, for example, there are 90,000 deaths on the road each year; many of those are adolescents and children.”

Dr. Flavia Bustreo, the assistant director-general at WHO, said, “Adolescents have been entirely absent from national health plans for decades.” The report proposes changing these plans and trying to help adolescents develop healthy lifestyle habits.

Costello said, “The roots of diabetes, of heart attacks, of strokes, of lung cancer, the root of that lies in the adolescent years, how the adolescents approach nutrition, and diet and exercise, whether they start to smoke or not, or abuse other substances.

Concept shift

Costello said countries need to create more adolescent friendly cities so adolescents have places to play, gather together safely and avoid gang violence.  

“Governments have got to invest in young people,” Costello said, because “they’re the future. We mustn’t be afraid to involve children in designing their own environments, in coming up with creative ideas, in working with peer groups, and investing in things that will give them an exciting life without exposing them to long term risks that could be avoidable.”

A study published in The Lancet in April shows that improving the physical, mental and sexual health of adolescents could result in significant economic returns. The study contends that an investment of about $4.60 per person per year would yield more than 10 times as much in benefits to society. This study was conducted by researchers from Victoria University and the University of Melbourne along with the United Nations Populations Fund.
