A group of ecologists has started creating a periodic table of ecological niches similar to chemistry's periodic table. It will be a critical resource for scientists seeking to understand how a warming climate may be spurring changes in species around the globe.

New findings published today in the Proceedings of the National Academy of Sciences of the United States of America by Desert Research Institute Professor Joseph R. McConnell, Ph.D., and colleagues document a 192-year series of volcanic eruptions in Antarctica that coincided with accelerated deglaciation about 17,700 years ago.

Researchers provide the first mechanical description of the jaws of a group of trap-jaw ants that can snap their spring-loaded jaws shut at speeds of up to 50 miles per hour--just fast enough to capture their elusive prey.

Record-low 2016 Antarctic sea ice due to 'perfect storm' of tropical, polar conditions

09/08/2017 09:13 PM EDT

The sudden, unexpected nosedive in Antarctic sea ice last year was due to a unique one-two punch from atmospheric conditions both in the tropical Pacific Ocean and around the South Pole.

New Brunswick engineers have discovered a simple, economical way to make a nano-sized device that can match the friendly neighborhood Avenger, on a much smaller scale. Their creation weighs 1.6 milligrams (about as much as five poppy seeds) and can lift 265 milligrams (the weight of about 825 poppy seeds) hundreds of times in a row.
