Study shows star formation influenced by environmental conditions

Science
Sept. 15 (UPI) -- Scientists at Niels Bohr Institute at the University of Copenhagen have determined that new star formation is influenced by local environmental conditions.According to the classical model, a star is formed when a prestellar core, a roundish accumulation containing 99 percent gas and 1 percent dust, collapses due to overweight, resulting in the formation of a star in the center of the collapse. This is followed by the formation of a disk of gas and dust rotating around said star."This is the star's protoplanetary disk, and planets are thought to be formed in such disks -- planet Earth being no exception," Michael K├╝ffmeier, astrophysicist at the institute, said in a press release.Researchers from the institute carried out computer simulations of the formation of hundreds o

Study shows Arctic sea ice continues to melt considerably

Science
Sept. 15 (UPI) -- Arctic sea ice shrank to roughly 4.7 million square kilometers in September, making the sea ice extent in 2017 far below numbers from 1979 to 2006.Scientists from the Alfred Wegener Institute, the University of Bremen and Universitat Hamburg reported Friday that the minimum sea ice extent for 2017 is average for the past 10 years, despite being far below average from previous decades.The sea ice in the Arctic is considered a critical element in climate processes and a vital early-warning system for global warming. Researches point to the September minimum extent as an important indicator of climate change.Sea ice covered area is measured using high-resolution microwave satellites, with data provided by the University of Bremen and Universitat Hamburg.According to research...
Study shows impact of global warming on coffee production

Study shows impact of global warming on coffee production

Science
Sept. 11 (UPI) -- A recent study by the University of Vermont found global warming could reduce coffee growing areas in Latin America by as much as 88 percent by 2050.Researchers from the University of Vermont's Gund Institute for Environment found climate change will continue to negatively impact coffee production, as well as bee populations, essential to coffee farming."Coffee is one of the most valuable commodities on earth, and needs a suitable climate and pollinating bees to produce well," Taylor Ricketts, director of the UVM's Gund Institute for Environment, said in a press release. "This is the first study to show how both will likely change under global warming -- in ways that will hit coffee producers hard."The study, published today in the Proceedings of the National Academy of S...

North Korea nuclear site shows 'disturbances,' landslides

World
Sept. 5 (UPI) -- Satellite imagery taken of North Korea's nuclear site a day after its sixth nuclear test shows numerous "surface disturbances" and landslides, according to analysts writing for 38 North, the Johns Hopkins University website dedicated to North Korea issues.The images were taken on Sept. 4, in the aftermath of the artificial quake generated after a 100-kiloton explosion rocked the area -- and tremors were felt across the China border and as far as Vladivostok, Russia."These disturbances are more numerous and widespread than what we have seen from any of the five tests North Korea previously conducted," say analysts Frank V. Pabian, Joseph S. Bermudez Jr., and Jack Liu.Tremors have lifted out fields, but the powerful explosion on Sunday did not trigger a mountain collapse -- ...
