Area affected by wildfires in Europe could almost triple due to climate change‎

Increasingly hot, dry and windy conditions could substantially extend the area affected by wildfires across Europe, according to a new study led by the Potsdam Institute for Climate Impact Research (PIK) with contributions from the Senckenberg Society for Nature Research. In a low-emissions scenario (SSP1-2.6), the researchers calculate that roughly 39% more land would be burned per year by the end of the century compared with today's average. In a high-emissions scenario (SSP3-7.0), it would be around 192%.

Warming waters draw summer 'feeding frenzies' by whales off Greenland‎

The effects of global warming depend on species: The losers are legion, but a lucky few are winners. Now, researchers have shown that baleen whales are taking advantage of a newly opened-up fish bonanza in the Greenland Sea, east of Greenland and reaching to the Arctic Circle and beyond.

Levitating molten metal on ISS could refine ultra-strong metallic glass‎

The research team led by materials scientist Ralf Busch from Saarland University is preparing for its first science-in-space mission. If everything goes to plan, from 31 August the researchers will spend one week remotely studying metallic-glass alloys in experiments carried out on board the International Space Station, ISS. Working with the European Space Agency, ESA, and the German Aerospace Center, DLR, the team will investigate the properties of these alloys using hot, levitating droplets.

Innovation enhances multiomics workflow, eliminates sample preparation‎

A patent-pending method developed and tested for multiple applications at Purdue University eliminates sample preparation, a bottleneck that currently dominates a laboratory scientist's time and budget, and enables spatial analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
