The impact of coastal hardening on local ecosystems

A team of researchers affiliated with several institutions in New Zealand and Australia has created a model to forecast coastal hardening around the world in the coming years. In their paper published in the journal Nature ...

Solving the space junk problem

Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, ...

Scientists track giant ocean vortex from space

Researchers have found a new way to use satellites to monitor the Great Whirl, a massive whirlpool the size of Colorado that forms each year off the coast of East Africa, they report in a new study.

New model accurately predicts harmful space weather

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt. A paper recently published ...

Melting glaciers causing sea levels to rise at ever greater rates

Melting ice sheets in Greenland and the Antarctic as well as ice melt from glaciers all over the world are causing sea levels to rise. Glaciers alone have lost more than 9 trillion tons of ice since 1961, raising water levels ...
