Biodiversity loss shifts flowering phenology at same magnitude as global warming

Fri, 24 Mar 2017 00:00:00 EDT

(Columbia University) Researchers have revealed that declining plant diversity -- from habitat loss, human use, and other environmental pressures -- causes plants to flower earlier, and that the effects of diversity loss on the timing of flowering are similar in magnitude to the effects of global warming. The finding could have a powerful influence on the way scientists study ecosystem changes and measure the effects of global warming.

NASA sees Tropical Cyclone Caleb's heaviest rainfall

Fri, 24 Mar 2017 00:00:00 EDT

(NASA/Goddard Space Flight Center) Tropical cyclone Caleb formed on March 23 in the South Indian Ocean southwest of the Indonesian Island of Sumatra. The GPM core observatory satellite had a fairly good view of the newly formed tropical cyclone when it flew overhead and analyzed its rainfall and found the heaviest precipitation was affected by westerly winds.

Why do guillemot chicks leap from the nest before they can fly?

Fri, 24 Mar 2017 00:00:00 EDT

(Aarhus University) It looks like a spooky suicide when small, fluffy guillemot chicks leap from the cliffs and fall several hundred meters towards the sea -- long before they are fully fledged. But researchers have now discovered that there is good reason behind this seeming madness.



Spread of ages is key to impact of disease, animal study finds

Fri, 24 Mar 2017 00:00:00 EDT

(University of Edinburgh) How a disease outbreak affects a group of animals depends on the breakdown of ages in the population, research has shown.



WPI, BSEE, and the US Coast Guard successfully test a novel oil spill cleanup technology

Thu, 23 Mar 2017 00:00:00 EDT

(Worcester Polytechnic Institute) Tests of a novel technology that can accelerate the combustion of crude oil floating on water demonstrated its potential to become an effective tool for minimizing the environmental impact of oil spills. The Flame Refluxer, developed by fire protection engineering researchers at Worcester Polytechnic Institute with funding from the Bureau of Safety and Environmental Enforcement, could make it possible to burn off spilled oil quickly while producing relatively low levels of air pollutants.
