Forests such as the Amazon rainforest emit huge amounts of biogenic volatile organic compounds (BVOC) into the atmosphere. These compounds impact the physical and chemical properties of the atmosphere and also our climate. The molecules react rapidly with ambient OH radicals and ozone, thereby influencing the oxidation capacity of the atmosphere for pollutants such as carbon monoxide and greenhouse gases such as methane. Furthermore, BVOC are precursors to secondary organic aerosols, which affect the Earth's radiative budget.

Scientists of the School of Natural Sciences of Far Eastern Federal University (SNS FEFU) with colleagues from Russia, South Korea, and Australia suggest the breaking new ground approach to manage spin-electronic properties and functionality of the thin-film magnetic nanosystems. The method is important for the development of a new generation of tiny electronics (spin-orbitronics) and superfast high-capacity computer memory. A related article appears in NPG Asia Materials.

When the body can no longer compensate the gradual failure of the liver caused by liver cirrhosis, there is a high risk of acute decompensated liver cirrhosis. In some patients this develops quickly into an often deadly acute-on-chronic liver failure, in which other organs such as the kidneys or brain fail. A study by an international team of researchers headed by Professor Jonel Trebicka from the Frankfurt University Hospital and funded by the foundation EF Clif, has discovered which patients are particularly at risk.

Global warming is dramatically increasing the risk of extreme hurricanes in the Caribbean, but meeting more ambitious climate change goals could up to halve the likelihood of such disasters in the region, according to new research.

The study, led by the University of Bristol, analysed future projections of hurricane rainfall in the Caribbean and found it to be particularly vulnerable to climate change, resulting in extreme hurricane rainfall events being as much as five times more likely in a warmer world.

DARIEN, IL – Public health and safety would benefit from eliminating daylight saving time, according to a position statement from the American Academy of Sleep Medicine.

NASA infrared imagery shows that newly formed Tropical Storm Iselle is already battling for its life under wind shear.

Tropical Depression 14E formed in the Eastern Pacific Ocean on Aug. 26 by 11 a.m. EDT (1500 UTC). By 5 p.m. EDT, it strengthened into a tropical storm and was re-named Iselle.

By detecting subtle differences in the way that Alzheimer's sufferers use language, researchers at Stevens Institute of Technology have developed an A.I. algorithm that promises to accurately diagnose Alzheimer's without the need for expensive scans or in-person testing. The software not only can diagnose Alzheimer's, at negligible cost, with more than 95 percent accuracy, but is also capable of explaining its conclusions, allowing physicians to double check the accuracy of its diagnosis.
