Study ties fracking to another type of earthquakes

New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes.

Scientists discover how trilobites survived environmental change

Scientists have worked out how one unusual species of trilobite—an ancient, sea-dwelling relative of spiders and lobsters—was able to defend itself against predators and survive a bumpy ride as Earth's oxygen levels fluctuated.

Study improves understanding of how bacteria benefit plant growth

Plants form alliances with microbes in the soil in which they grow. Legumes, for example, benefit from a symbiotic relationship with microbes that inhabit nodules in their roots and "fix" nitrogen in the atmosphere to make ...

Chemists develop new method to create chiral structures

Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. Called chirality, it is a property these molecules have due to their asymmetry. ...
