Chile’s 12,000 square kilometer (4,633 square mile) Southern Patagonia Ice Field split in two and is likely to continue to fracture amid climate change, according to a team of Chilean scientists who were in the region in March.

Gino Casassa, chief of the Snow and Glacier Division of Chile’s DGA water authority, told Reuters increasing temperatures along the Andes Mountains in southern Chile and Argentina have meant less snow and ice to replenish the region’s abundant glaciers.

“What occurred is a fracture as the ice has retreated, Casassa said.

The chunk of ice that split off from the main glacier was estimated at 208 square kilometers (80.3 square miles), a relatively small part of the ice field.

But Casassa said it may be a sign of things to come.

The ice field, he said, is now “split in two, and we’ll likely discover further divisions to the south,” he said.

Two icebergs broke off the Grey Glacier in southern Chile’s Torres del Paine National Park earlier this year, adding to fears that such ruptures are becoming more frequent.

East African countries are set to ban skin-lightening products that contain hydroquinone, a medical agent linked to health problems when used in high concentrations. The East African Legislative Assembly last week passed a resolution calling for a region-wide ban on the manufacturing and importation of products containing hydroquinone.

At a beauty parlor in Arusha, 52-year-old Rose Mselle has been using skin-bleaching products since she was a teenager. She says women like her want to be beautiful

“And in the process of looking for beauty, or for our skin color to shine, we use things that we shouldn’t,” she added.

At a nearby market, 32-year-old clothing vendor Janet Jonijosefu used skin-lightening products that contain hydroquinone, a medical agent used to treat dark spots, for years. She stopped after her skin became fragile.

She said the beauty products containing hydroquinone badly affected her skin. She started developing patches on her face. She went to the doctor and was advised to stop using products containing hydroquinone and instead use aloe vera.

Skin-lightening products often use high concentrations of hydroquinone, which can cause skin problems or become toxic when mixed with other bleaching chemicals.

Ghana, Ivory Coast, Kenya, Nigeria, Rwanda, and South Africa ban or regulate the agent in cosmetics. Tanzania bars imports. 

The East African Legislative Assembly last week passed a resolution on a region-wide ban of hydroquinone’s manufacture and importation.

Suzan Nakawuki, a member of the regional assembly from Uganda, noted that hydroquinone is not only used by women but also men.

“We have seen men bleaching seriously even more than women,” she said. “But it’s becoming a problem. If we don’t regulate it, it is going to become very problematic.”

When used medically, hydroquinone can be an effective treatment for skin discoloration. Some East African lawmakers spoke out against a blanket ban.

Aden Abdikadir, a lawmaker from Kenya, said he is concerned a blanket ban  will cause “serious trade disruption” for cosmetics.

If signed by heads of state, the ban becomes law in all six East African Community states, which include Burundi, Kenya, Rwanda, South Sudan, Tanzania and Uganda.

Critics point out bans on hydroquinone have failed to stop smuggled products from being sold openly. Cosmetics labeled as having hydroquinone are on display at shops in Arusha.

If bans are not backed by enforcement, they will have little effect on the use of the high demand skin-lightening products, despite the risk to health.

The World Health Organization has certified Algeria and Argentina as malaria-free, following three consecutive years where no new cases of the deadly disease have been reported. 

The malaria parasite, which kills more than 400,000 people each year, was discovered in Algeria in 1880. Most of the victims are children under the age of five in Africa.

The World Health Organization reports Algeria is the second country in Africa to be recognized as malaria-free after Mauritius, which was certified in 1973. Argentina is the second country in South America, after Paraguay, to be declared malaria-free.

A combination of many factors has made the achievements possible, according to WHO spokeswoman Fadela Chaib.

“It is very good news for Algeria and Argentina, but also for the two continents and globally also,” Chaib told VOA. “It means that malaria can be beaten. But the efforts should continue because we need also to enhance surveillance to be able to detect if any cases of malaria are still present in the country.”

WHO says the two countries eliminated malaria by employing a number of basic, well-proven measures, including insecticide-treated mosquito nets. It says both countries improved surveillance, which enabled them to rapidly identify and treat new cases of malaria. In addition, the two countries provided free diagnosis and treatment within their borders.

In the case of Argentina, WHO says cross-border collaboration with its neighbor Bolivia was critical in combating the disease. It says both countries teamed up to spray more than 22,000 homes in border areas and to conduct widespread malaria testing.

WHO says Algeria’s and Argentina’s unwavering commitment, perseverance and success in combating malaria should serve as a model for other countries.

Both Algeria and Argentina have succeeded in ridding themselves of the deadly malaria parasite without the benefit of a vaccine. Health officials are hopeful this task becomes easier with the recent rollout of the first promising malaria vaccine in Ghana and Malawi.

Every year, 8 million tons of waste suffocate beaches and sea beds, says Italy’s environment league, Legambiente. Its Beach Litter report issued this week revealed that more than 80 percent of the waste found on 93 beaches was plastic. 

A mass cleanup is planned next weekend, involving thousands of volunteers on 250 beaches and coastal sites. Legambiente, which organized the effort, also urged the government to approve the Salvamare (Save Our Seas) bill that would allow fishermen to bring to shore any plastic that ends up in their nets, without having to pay for disposal costs.

Greenpeace Italy sounded its alarm this week when a young sperm whale washed ashore on a Sicilian beach with plastic in its stomach. Giorgia Monti, campaign manager for Greenpeace, said five sperm whales had beached in the last five months in Italy. She could not confirm whether plastic was the cause of the death of the last whale found, but said it was very likely.

“The sea is sending us a cry of alarm, a desperate SOS,” Monti said.

Later this month, Greenpeace is launching an effort to monitor plastic pollution levels at sea, with a focus on the west coast of Italy. 

To stem the tide of plastic waste, initiatives have been spearheaded across Italy. Among new technology to combat pollution in many Italian ports are filters called sea-bins, which are active 24 hours and able to capture more than 1.5 kilograms of plastic daily. 

While campaigners say much more needs to be done, some tourist resorts have banned the use of non-recyclable plastic and fine violators.

A Belgian abbey is reviving its centuries-old tradition of beer-making after 220 years. The monks at Grimbergen Abbey are using ancient recipes to offer specialty beers in their new microbrewery. Meanwhile, researchers in Israel have made beer with yeast from jars that are thousands of years old. Beer is one of the oldest beverages, but producers are making new and attractive brews. As VOA Zlatica Hoke reports, there is a growing interest in traditional beers and the history of brewing.

People using e-cigarettes to quit smoking are about 95% more likely to report success than those trying to quit without help from any stop-smoking aids according to the results of a large study in England.

The research, funded by the charity Cancer Research UK and published in the journal Addiction on Thursday, analyzed success rates of several common stop-smoking methods – including e-cigarettes, nicotine replacement therapy (NRT) patches and gum, and Pfizer’s varenicline, sold as Champix in the UK.

It also adjusted for a wide range of factors that might influence success rates for quitting – such as age, social level, degree of cigarette addiction, previous attempts to quit, and whether quitting was gradual or abrupt.

Latest World Health Organization data show that smoking and other tobacco use kills more than 7 million people a year globally. Of the 1.1 billion people worldwide who smoke, around 80 percent live in poor or middle-income countries.

E-cigarettes have no tobacco, but contain nicotine-laced liquids that the user inhales in a vapor. Many big tobacco companies, including British American Tobacco, Imperial Brands and Japan Tobacco, sell e-cigarettes.

This study involved almost 19,000 people in England who had tried to quit smoking in the preceding 12 months, collected over a 12-year period from 2006 to 2018. Successful quitters were defined as those who said they were still not smoking.

As well as the 95% increased success rate for e-cigarettes, the study found that people prescribed Champix were around 82% more likely to have succeeded in stopping smoking than those who tried to quit without any aids.

“Our study adds to growing evidence that use of e-cigarettes can help smokers to quit,” said Sarah Jackson, a professor at University College London who co-led the study.

Using e-cigarettes, or ‘vaping,’ is considered by many experts to be an effective way for smokers to give up tobacco, but some in the scientific community are skeptical of their public health benefits, fearing they might normalize the idea of smoking and lead young people into the habit.

Smokers who were prescribed NRT by a medical professional were 34% more likely to quit successfully, the study found. But those buying NRT from shops were no more likely to succeed that those trying to quit without any help at all.

Experts said the results were robust and important.

Peter Hajek, director of the tobacco dependence research unit at Britain’s Queen Mary University of London, said the study yielded two key findings about e-cigarettes:

“They help smokers quit at least as much as stop-smoking medications, and they are used by many more smokers. This means they generate many more quitters and do this at no cost to the NHS (National Health Service),” he said in an emailed comment.

The U.S. opioid crisis is taking a toll on children of users as a study published on Wednesday showed they were more likely to attempt suicide.

The study in JAMA Psychiatry published by the American Medical Association found children whose parents were prescribed opioids were twice as likely to attempt suicide as the offspring of people who did not use those drugs.

The latest study from researchers at the University of Chicago and the University of Pittsburgh is the first research attempting to tie rising suicides among U.S. children to the opioid crisis.

“I think that it’s obvious in many ways; it’s just that we were able to put it together and prove it,” said Dr. David Brent, one of the authors of the study.

Brent, of the University of Pittsburgh, said he believes some opioid users might display less care, monitoring and affection for their children, which would explain the higher suicide rate in those kids.

Suicide increased across all ages in the United States between 1999 and 2016, spiking by over 30% in half the country, the U.S. Centers for Disease Control and Prevention reported last year.

Another study found that among girls age 10 to 14 the suicide rate rose by 12.7% per year after 2007.

In the latest study, researchers used medical insurance data from 2010 to 2016 for more than 300,000 children ages 10 to 19, and broke that group down into those whose parents were prescribed opioid drugs and those whose parents were not.

Among the children of parents who used opioids, 0.37% attempted suicide, compared to 0.14 % of the children of non-users, according to the study, which was funded by the National Institutes of Health.

The parents were all legally prescribed opioids that they used for at least a year. The study did not identify which of those users may have been abusing painkillers, as opposed to using them in line with doctor recommendations.

Challenges for children of drug users

Children of opioid users still had a significantly higher risk of attempting suicide after researchers adjusted for factors such as depression and parental history of suicide.

Some researchers have suggested social media could harm children’s self esteem and increase their suicide risk.

But Brent and his co-authors noted social media is prevalent in countries that have not seen a rise in child suicide.

U.S. President Donald Trump declared the opioid crisis a public health emergency in October 2017 and has promised to hold drugmakers accountable for their part in the crisis.

Nearly 400,000 people died of overdoses between 1999 and 2017 in the United States, resulting in the lowering of overall life expectancy for the first in more than 60 years, according to data from the Centers for Disease Control and Prevention.

Eric Rice, an associate professor at the University of Southern California’s school of social work, said other research has found children of drug users face challenges.

“A doubling in the suicide rate is a pretty shocking manifestation of that, I’ve got to be honest,” Rice said. “But to hear that there are impacts on children which are negative is not a surprising thing,” said Rice, who was not involved with the study.

Scientists say they have pinpointed the source of a globally banned chemical that damages the Earth’s protective ozone layer: China. 

In a report published Wednesday in the journal Nature, the scientists who monitor the planet’s atmosphere say the recent rise in the emission of the ozone-depleting chemical CFC-11 has been traced to two provinces in eastern China. 

Any production and use of CFC-11 is a violation of the Montreal Protocol, a 1987 agreement that phased out chlorofluorocarbons that cause damage to the ozone layer. 

Ozone is critical to life, limiting the amount of harmful ultraviolet solar radiation that reaches Earth’s surface. The recovery of the ozone had been touted as an environmental success story. But since 2012, air samples had shown a troubling amount of CFC-11 present in them. Because the chemical doesn’t occur in nature, it indicated an illegal use of the chemical.

Over the last two years, scientists have used air monitoring stations in Japan and Korea along with water studies to pinpoint the offenders as foam factories in the provinces of Shandong and Hebei in eastern China.

Scientists say the report will help Chinese authorities find the exact sources and stop the emissions before they deal a major setback to ozone hole recovery.
