Coinfection with visceral leishmaniasis (VL) and human immunodeficiency virus (HIV) has been observed in at least 35 countries on four continents and requires special case management. Currently, the W..

In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists have now used these measurements..

Researchers have for the first time created artificial cell assemblies that can communicate with each other. The cells, separated by fatty membranes, exchange small chemical signaling molecules to tri..

Taking advantage of recent advances in using theoretical calculations to predict the properties of new materials, researchers have discovered a new class of half-Heusler thermoelectric compounds, incl..

A study in rodents found that the brain's cerebellum — known to play a role in motor coordination — also helps control the brain's reward circuitry. Researchers found a direct neural conne..

Scientists have developed a gene therapy that blocks axonal degeneration, preventing axon destruction in mice and suggesting a therapeutic strategy that could help prevent the loss of peripheral nerve..

Biologists studied the evolution of 40 molly and Limia species, and concluded dorsal fin displays arose first for males to compete with other males, only later being used in courtship displays to fema..

Researchers have discovered a set of genes that help to establish brain connections governing body weight.

When an advocate for one side of an issue announces that he or she now believes the opposite, can that message affect others' views? Research shows that such a conversion message can influence pu..
