Galaxies, including our own Milky Way, consist of hundreds of billions of stars. How did such gigantic galactic systems come into being? When galaxies are born, do their stars form everywhere at once, or only within a small core region? Recent measurements provide the first concrete evidence that star-forming regions in infant galaxies are indeed [...]

An expert in materials science and engineering has found that graphite oxide sheets — which are used to make graphene, a hotly studied material that scientists believe could be used to produce low-cost transparent and flexible electronics — can be assembled into a continuous membrane that could be used as the basis for transparent conductors.
Nearly half of patients with heart failure have problems with memory and other aspects of cognitive functioning, reports a new study.

A new open-source software package is making it possible to do complex simulations of molecular motion on desktop computers at much faster speeds than has been previously possible. “Simulations that used to take three years can now be completed in a few days,” according to developers.
New research could help explain why some alcoholics are more severe drinkers than others. Scientists have found strong evidence that the serotonin transporter gene, SLC6A4, plays a significant role in influencing drinking intensity among alcohol-dependent individuals.

The global climate is changing, and this change is already impacting food supply and security. People living in regions already affected by aridity need plants that can thrive / grow under dry conditions.
Sleep duration is associated with changes in the levels of specific cytokines that are important in regulating inflammation. The results suggest that inflammation may be the pathway linking extreme sleep durations to an increased risk for disease.
