The hole in Earth's ozone layer is healing, first-of-its kind study shows
19 January 2018 - Efforts to heal the hole in Earth's ozone layer over Antarctica appear to be paying off, according to a new, first-of-its-kind study that looked directly at ozone-destroying chemicals in the atmosphere. Earth's ozone layer protects the planet's surface from some of the sun's more harmful rays that can cause cancer and cataracts in humans, and damage plant life, according to NASA. In the mid-1980s, researchers identified a massive hole in the ozone layer over Antarctica and determined that it had been caused largely by human-produced chemicals called chlorofluorocarbons (CFCs).

Award-winning Nepalese farmers grow bananas to avert floods
19 January 2018 - Simpalpani and neighbouring villages -- which sit on a geological faultline -- have been struck by 16 massive landslides over the last 50 years, aid workers said. Rising global temperatures have shrunk Nepal's glaciers, with meltwater forming lakes that flood regularly, causing widespread destruction. But farmers clearing forests for agriculture are also to blame, experts say. Since 2010, the charity [National Disaster Risk Reduction Centre Nepal] has been teaching 14,000 families in 28 villages in the Banganga basin, a river of religious significance for Hindus in Nepal and home to an important wetland, to change their farming habits. Mapping data shows that slash and burn farming in the area has fallen by 80 percent since the project began, [executive director Dhruba Gautam] said. Farmers have persuaded each other to adopt practices that protect forests, soil, rivers, and wetlands, as well as earning a better living. (more)

Down to business: Drought-hit Kenyan women trade their way out of poverty
19 January 2018 - Widow Ahatho Turuga lost 20 of her goats to drought early last year, but the shopkeeper is planning to reinvest in her herd once she has saved enough money. ... Turuga is finding it easier to cope since taking part in a rural entrepreneurship programme run by The BOMA Project, a non-profit helping women in Kenya's dry northern areas beat extreme poverty and adapt to climate change. The U.S. and Kenya-based organization provides two years of business and life-skills training, as well as mentorship. Groups of three women are each given a start-up grant of 20,000 Kenyan shillings ($194.55) and a progress grant of 10,000 shillings to set up a business. After graduating, they carry on operating their businesses -- mainly small shops selling groceries and household goods -- either together or on their own. (more)

Blood test to detect 8 cancers early gives promising results
18 January 2018 - Scientists are reporting progress on a blood test to detect many types of cancer at an early stage, including some of the most deadly ones that lack screening tools now. Many groups are working on liquid biopsy tests, which look for DNA and other things that tumors shed into blood, to try to find cancer before it spreads, when chances of cure are best. In a study Thursday (18 January) in the journal Science, Johns Hopkins University scientists looked to see how well their experimental test detected cancer in people already known to have the disease. The blood tests found about 70 percent of eight common types of cancer in the 1,005 patients. In many cases, the test narrowed the possible origin of the cancer to one or two places . . . (more)

The government says the UK is cutting emissions faster than any other G7 nation -- and the committee agrees there has been a big shift under [Prime Minister] Theresa May. (more)

US: Hidden cameras help scientists study elusive wildlife
17 January 2018 - Some charismatic critters caught by motion-detecting wildlife cameras seem to know how to strike a pose. But it's not just show business. As these devices get ever smaller, cheaper, and more reliable, scientists across the U.S. are using them to document elusive creatures like never before. 'There's no doubt -- it is an incredible tool to acquire data on wildlife,' said Grant Harris, a U.S. Fish and Wildlife Service wildlife biologist based in Albuquerque, New Mexico. (more)

Solar steam powers homes - and new jobs - in South Africa
11 January 2018 - South Africa may still get most of its energy from coal, but in the country's sunny Northern Cape province, a different electricity source is taking hold: solar steam. A Spanish renewable energy company has opened three thermal solar plants -- which use the sun's heat to turn water into steam -- in the province. The steam is then used to drive turbines to produce electricity -- enough to provide electrical power to just short of a million people, or almost the province's entire population, according its operators.

Time with grandparents may impact how kids view the elderly
11 January 2018 - Children and teens who spend a lot of time with their grandparents may be less likely than peers who don't to have negative and stereotypical ideas about the elderly, a recent study suggests. Researchers in Belgium asked 1,151 youth ranging in age from 7 to 16 years about the time they spent with grandparents as well as their opinions about aging and the elderly. Growing evidence also suggests that contact between grandchildren and grandparents can be good for both, said Dominic Abrams, a psychology researcher at the University of Kent, in the UK. 'More time that is enjoyable and positive really makes the biggest difference. I think there are several ways that this works,' Abrams, who wasn't involved in the study, said by email. (more)
