Researchers have used fossilized teeth found near Lake Turkana in northwest Kenya to identify a new monkey species—a discovery that helps fill a 6-million-year gap in primate evolution.

Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with University of Nevada Las Vegas (UNLV) have discovered a previously unknown pressure induced phase transition for TATB that can help predict detonation performance and safety of the explosive. The research appears in the May 13 online edition of the Applied Physics Letters and it is highlighted as a cover and featured article.

A global helium shortage is impacting businesses large and small. Local businesses that rely on the non-renewable gas are making due without any idea of when or if helium will be readily available again.

A major helium shortage could deflate your next party or celebration.

An undated photo at Grand Canyon National Park shows the fossilized tracks of an unidentified creature that researchers believe lived about 315 million years ago.

When Americans celebrated the first Earth Day on April 22, 1970, the planet's atmosphere was markedly different than it is today. Nearly 50 years ago, scientists measured Earth's levels of carbon dioxide — the planet's most important greenhouse gas — at around 325 parts per million, or ppm.

On 22 March 2015, NASA's Chandra X-ray observatory recorded a blip in its data. Not far from the southern constellation of Fornax, something brightened, then slowly faded away.

An international team of astronomers, including faculty and alumni from UNLV, has discovered a new way to spot when collisions occur in distant galaxies between two neutron stars - incredibly dense, city-sized celestial bodies that possess the most powerful magnetic fields in the universe.

In October 2017, astronomers announced the first detection of gravitational waves from the merger of two neutron stars earlier that year. The event also rung in the era of multi-messenger astronomy, as more than 70 telescopes observed the event’s afterglow in optical light, X-rays, gamma rays, and more. Now, an X-ray signal dubbed XT2 from a galaxy 6.6 billion light-years away has revealed another neutron star merger, which left behind a single, heavier neutron star with an incredibly powerful magnetic field: a magnetar.

This event likely signaled the merger of two neutron stars—dense stellar objects packed mainly with neutrons—and could give astronomers fresh insight into how neutron stars are built.

A bright burst of X-rays has been discovered by NASA’s Chandra X-ray Observatory in a galaxy 6.6 billion light years from Earth. This event likely signaled the merger of two neutron stars — dense stellar objects packed mainly with neutrons — and could give astronomers fresh insight into how neutron stars are built. A paper describing the research, conducted by an international team of astronomers, including researchers and alumni from Penn State, appears in the journal Nature.
