Last week, the Nobel Prize in chemistry was awarded to John Goodenough, Stanley Whittingham and Akira Yoshino for their work developing the lithium-ion battery. The Royal Swedish Academy of Sciences, in announcing the award, said the three men “created a rechargeable world.” The ubiquitous battery is now found in items as varied as hearing aids and power grids. It is a testament not just to technological revolutions, but also to the power of advancements in performance and decreases in cost.

UNITED NATIONS (AP) — One-third of children worldwide under age 5 — about 200 million youngsters — are either undernourished or overweight, undermining their full potential to grow and develop, the U.N. children’s agency said in a report Tuesday.

UNICEF also said almost two-thirds of children aged 6 months to 2 years are not fed food that supports their rapidly growing bodies and brains. Tiếp tục đọc “UN: 200 million children under 5 eat too little or too much” →

World Mental Health Day 2019 focuses on raising awareness of the scale of suicide around the world and the role that each of us can play to help prevent it.

10 October 2019 – WHO

Worldwide, 800,000 people die by suicide each year – one every 40 seconds – making it the second leading cause of death among young people (aged 15 to 29), the World Health Organization (WHO) said on Thursday, spotlighting suicide prevention as the theme for this year’s World Mental Health Day.

“Mental health has been neglected for too long,” Secretary-General António Guterres said in a video message for the Day, saying it needs to be addressed urgently, as a matter “that concerns us all.” Tiếp tục đọc “World Mental Health Day sheds light on worrying rates of youth suicide” →

New Elevation Measure Shows Climate Change Could Quickly Swamp the Mekong Delta

A stunning 12 million people could be displaced by flooding in Vietnam’s Mekong Delta within half a century, according to new research led by Philip Minderhoud, a geographer at Utrecht University in the Netherlands. Minderhoud and his colleagues arrived at that surprising conclusion after analyzing ground-based measurements of the Mekong’s topography that the Vietnamese government shielded from Western scientists  for years. The results, published today in Nature Communications, show the Mekong’s elevation over sea level averages just 0.8 meter, which is almost two meters lower than commonly quoted estimates based on freely available satellite data.

Fires raging in Brazil‘s Amazon rainforest have hit a record high number this year, according to new data from the country’s space research agency, as concerns grow over President Jair Bolsonaro‘s management of the environment.

Nearly 73,000 fires were recorded between January and August, compared with 39,759 in all of 2018, the National Institute for Space Research (INPE) said on Monday. The surge marks an 83 percent increase over the same period last year and is the highest since INPE records began in 2013.

Iceland has marked its first-ever loss of a glacier to climate change as scientists warn that hundreds of other ice sheets on the subarctic island risk the same fate.

As the world recently marked the warmest July ever on record, a bronze plaque was mounted on a bare rock in a ceremony on the barren terrain once covered by the Okjökull glacier in western Iceland.

An estimated 1.7 million people in Hong Kong – a quarter of the population – defied police orders to stage a peaceful march after a rally in a downtown park, after two months of increasingly violent clashes that have prompted severe warnings from Beijing and failed to win concessions from the city’s government.

Huge crowds filled Victoria Park on Sunday afternoon and spilled on to nearby streets, forcing police to block traffic in the area. Torrential rain came down an hour into the rally, turning the park into a sea of umbrellas. At the same time, protesters walked towards Central, the heart of Hong Kong’s business district, and surrounded government headquarters.

The animated map above shows the radioactive cloud that moved through Europe following the Chernobyl nuclear disaster on 26 April 1986. The Chernobyl accident remains the worst nuclear accident in history and is one of only two events classified as a “level 7 major accident” (the other being the 2011 Fukushima disaster in Japan).

Overall, the initial explosion killed 2 people, with 28 more firemen and employees dying as a result of acute radiation syndrome over the coming months.

Estimates of the total number of deaths caused by the release of radiation vary widely from a low of 4,000 in a UN study up to 200,000 according to Greenpeace.

In what may be the week’s most unsurprising news, scientists have officially announced that this past July was the hottest month ever recorded on Earth.

According to data released yesterday by the Copernicus Climate Change Service, a program of the European Centre for Medium-Range Weather Forecasts, last month edged out July 2016, the previous record-holder, for the title.

Last month was 0.04 degree Celsius, or about 0.07 degree Fahrenheit, warmer than July 2016. And it was more than 1 F warmer than the average July between 1981 and 2010.

Hai phần ba con sông trên thế giới không còn được chảy tự do nữa

~ Đào Thu Hằng ~ %(count) bình luận

English: Two-thirds of Earth’s longest rivers no longer free-flowing

  • Chỉ một phần ba trong số 242 con sông dài nhất thế giới vẫn có dòng chảy không gián đoạn suốt chiều dài, đa số các con sông không gián đoạn nằm ở những vùng hẻo lánh ở Bắc Cực, lưu vực sông Amazon, và lưu vực sông Congo, theo như một nghiên cứu sắp xuất bản trên tạp chí Nature.
  • Nhóm chuyên gia quốc tế thực hiện nghiên cứu này, dẫn đầu bởi Gunther Grill thuộc ĐH McGill (Canada) xác định rằng trong số 91 con sông có chiều dài hơn 1000 ki-lô-mét (khoảng 600 dặm) đổ ra biển, chỉ còn 21 dòng vẫn có dòng chảy không bị cản trở từ thượng nguồn ra đến biển.
  • Các con đập và những hồ đập chứa nước là nguyên nhân lớn nhất cản trở dòng chảy của sông, các nhà nghiên cứu tuyên bố. Hiện tại trên thế giới đã có gần 60000 đập lớn, và có đến 3700 đập thủy điện lớn nữa đang trong quá trình lên kế hoạch hoặc đang xây dựng.
  • Những con sông khỏe mạnh mang lại nhiều lợi ích cho con người, từ hoạt động vui chơi đến đảm bảo lương thực. Đảm bảo sự liên kết của những con sông tự do còn lại trên thế giới cũng mang tính tối quan trọng để bảo tồn đa dạng sinh học của những hệ thống nước ngọt.
