New drought atlas maps 2,000 years of climate in Europe

The long history of severe droughts across Europe and the Mediterranean has largely been told through historical documents and ancient journals, each chronicling the impact in a geographically restricted area. Now, for the ...

VISTA discovers new component of Milky Way

Astronomers using the VISTA telescope at ESO's Paranal Observatory have discovered a previously unknown component of the Milky Way. By mapping out the locations of a class of stars that vary in brightness called Cepheids, ...

Team finds weather extremes harmful to grasslands

Fluctuations in extreme weather events, such as heavy rains and droughts, are affecting ecosystems in unexpected ways—creating "winners and losers" among plant species that humans depend upon for food.

When fruit flies get sick, their offspring become more diverse

New research from North Carolina State University and Reed College shows that when fruit flies are attacked by parasites or bacteria they respond by producing offspring with greater genetic variability. This extra genetic ...

Climate change causes timing shifts in fish reproduction

Research by Rebecca Asch, a recent graduate of Scripps Institution of Oceanography at UC San Diego, shows a strong correlation between warmer ocean temperatures and changes in the timing of fish reproduction.

Delta Cephei's hidden companion

To measure distances in the universe, astronomers use cepheids, a family of variable stars whose luminosity varies with time. Their role as distance calibrators has brought them attention from researchers for more than a ...

Climate change does not cause extreme winters, new study shows

Cold snaps like the ones that hit the eastern United States in the past winters are not a consequence of climate change. Scientists at ETH Zurich and the California Institute of Technology have shown that global warming actually ...
