Saturn’s largest moon, Titan, looks to be the only place in the solar system — aside from our home planet, Earth — with copious quantities of liquid (largely, liquid methane and ethane) sitting on its surface. According to a planetary astronomer Earth and Titan share yet another feature, which is inextricably linked with that surface [...]

Researchers in Germany have identified a new antimicrobial peptide that demonstrates significant activity against a variety of bacteria, including multiresistant human strains such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). The discovery was made while investigating the ancient metazoan organism Hydra magnipapillata.
The damaging effects of the illicit drug Cannabis on young brains are worse than originally thought, according to a psychiatric researcher. A new study suggests that daily consumption of cannabis in teens can cause depression and anxiety, and have an irreversible long-term effect on the brain.

Intensive medical therapy, including aggressive control of blood pressure and cholesterol levels, for patients with asymptomatic plaque buildup in their carotid arteries (which supply blood to the brain) appears to be associated with reduced rates of cardiovascular events and reduced risk of microemboli (microscopic-sized blood clots) in the brain arteries, according to a new study.

Global warming is giving a boost to Sonoran Desert plants that have an edge during cold weather, according to new research. Although overall numbers of winter annuals have declined since 1982, species that germinate and grow better at low temperatures are becoming more common. As a result, the composition of the desert’s spring wildflower display [...]

Investigators surveyed 162 health-care providers to determine whether medical liability concerns were as important as antibiotic cost and formulary restrictions in selecting treatment regimens. They found a strong correlation between the prevalence of methicillin resistance and density of attorneys in countries in Europe and North America.

A network of cameras deployed around the Arctic in support of NASA’s THEMIS mission has made a startling discovery about the Northern Lights. Sometimes, vast curtains of aurora borealis collide, producing spectacular outbursts of light.

Despite their ability to fly, tropical birds waited until the formation of the land bridge between North and South America to move northward, according to a new study.
Not all regions of a tumor are equal in terms of their oxygen levels. One clinically important implication of this is that tumors with large areas with low levels of oxygen (areas known as hypoxic regions) are associated with poor prognosis and treatment response. Researchers have determined that a cellular response pathway known as the [...]
