World's coffee under threat, say experts

Science
The first full assessment of risks to the world's coffee plants shows that 60% of 124 known species are on the edge of extinction. More than 100 types of coffee tree grow naturally in forests, including two used for the coffee we drink.Scientists say the figure is "worrying", as wild coffee is critical for sustaining the global coffee crop.About one in five of the world's plants is threatened with extinction, and the 60% figure is an "extremely high" one. "If it wasn't for wild species we wouldn't have as much coffee to drink in the world today," said Dr Aaron Davis of the Royal Botanic Gardens, Kew."Because if you look at the history of coffee cultivation, we have used wild species to make the coffee crop sustainable." ...

AI identifies precancerous cervix better than human experts, report says

Health
Jan. 10 (UPI) -- A new artificial intelligence method could be key for future diagnosis of cervical cancer. The algorithm, developed by researchers at the National Cancer Institute, was 91 percent accurate in diagnosing cancer in women during a study in Costa Rica, according to findings published Thursday in the Journal of the National Cancer Institute. "Our findings show that a deep learning algorithm can use images collected during routine cervical cancer screening to identify precancerous changes that, if left untreated, may develop into cancer," Mark Schiffman, a researcher at the NCI's Division of Cancer Epidemiology and Genetics and study senior author, said in a news release. "In fact, the computer analysis of the images was better at identifying precancer than a human expert revie...

Frozen 'super-Earth' could support life, experts say

Technology
A frozen "super-Earth" discovered six light years from Earth could be capable of harbouring life, scientists have said. The rocky planet, at least 3.2 times the size of Earth, is orbiting Barnard's Star, one of the closest and most well studied red dwarf stars in the Galaxy and the sun's nearest neighbouring single star.Known as Barnard's star b, its surface temperatures are estimated at minus 150C. Despite this, scientists believe pockets of liquid water, warmed by geothermal activity, could lie beneath the ice capable of harbouring life.As a red dwarf, Barnard's star is smaller, older and much cooler than the sun. Although the planet is much closer to it than the Earth is to the sun, it's surface remains locked in a blanket of ice. Ima...
