Earth's lower mantle chemistry breakthrough

Breaking research news from a team of scientists led by Carnegie's Ho-kwang "Dave" Mao reveals that the composition of the Earth's lower mantle may be significantly different than previously thought. These results are to ...

NASA reveals new results from inside the ozone hole

NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.

Propofol discovery may aid development of new anesthetics

Researchers at Washington University School of Medicine in St. Louis and Imperial College London have identified the site where the widely used anesthetic drug propofol binds to receptors in the brain to sedate patients during ...

Seismologists puzzle over largest deep earthquake ever recorded

A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on ...

Deep Earth heat surprise

The key to understanding Earth's evolution is to look at how heat is conducted in the deep lower mantle—a region some 400 to 1,800 miles (660 to 2,900 kilometers) below the surface. Researchers at the Carnegie Institution, ...

Toshiba's low-power SRAM chip aims to cut device drain

(Phys.org)—Toshiba has announced a low-power embedded SRAM memory chip which may make future mobile devices last longer. Presenting its SRAM developments at the International Solid-State Circuit Conference in San Francisco ...

A human-caused climate change signal emerges from the noise

By comparing simulations from 20 different computer models to satellite observations, Lawrence Livermore climate scientists and colleagues from 16 other organizations have found that tropospheric and stratospheric temperature ...
