In contrast to pre-industrial climate fluctuations, current, anthropogenic climate change is occurring across the whole world at the same time, according to new studies. In addition, the speed of glob..

Observations made with a new instrument developed for use at the 2.1-meter telescope at the National Science Foundation's Kitt Peak National Observatory have led to the discovery of the fastest e..

Most game theory models don't reflect the relentlessly random timing of the real world. In a new article, two economists and a physicist model what happens when players receive information or act..

Use of medical imaging during pregnancy increased significantly in the United States, a new study has found, with nearly a four-fold rise over the last two decades in the number of women undergoing co..

In a major step toward developing portable scanners that can rapidly measure molecules in pharmaceuticals or classify tissue in patients' skin, researchers have created an imaging system that use..

Medical researchers have presented evidence for a shift to dolutegravir-containing antiretroviral treatment in South Africa.

The way in which that linear sequence of genes are packed into the nucleus determines which genes come into physical contact with each other, which in turn influences gene expression. Engineers have n..

Research is examining whether dragonfly-inspired computing could improve missile defense systems, which have the similar task of intercepting an object in flight, by making on-board computers smaller ..

Researchers are designing a nanoscale photon diode — a necessary component that could bring us closer to faster, more energy-efficient computers and communications that replace electricity with light..

Trees have many natural enemies, including pathogens that have evolved to attack certain tree species. Invasive tree species — even ones that are very closely related to native trees — are often not..
