Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. ESA plans to find out which it is. Either outcome is big news for a planet once thought to be [...]

A new particle gun fires liquid droplets less than a millionth of a meter in diameter, hundreds of thousands of times a second or faster. The sample jet sends the droplets across a tightly focused X-ray beam in single file, each droplet so small it contains only a single protein or virus.

Cognitive testing may help people with inactive or benign multiple sclerosis better predict their future with the disease, according to a new study. Gender and brain lesions may also determine the risk of progression of MS years after diagnosis.
Powerful new radio technologies that promise blisteringly fast WiFi have been given a boost by a team of researchers’ cutting-edge work on miniscule microchips.

Most older drivers are unaware of the potential impact on driving performance associated with taking medications, according to new research. The findings indicate that 95 percent of those age 55 and older have one or more medical conditions, 78 percent take one or more medications, and only 28 percent have an awareness of the risks [...]

One of the hottest topics in astronomy involves the study of the conditions favorable for the development and survival of primordial life. New research shows that compared to middle-aged stars like the Sun, newly formed stars spin faster generating strong magnetic fields that result in emission of more intense levels of radiation — all of [...]

NOAA will lead a three-week research expedition in August to study World War II shipwrecks sunk in 1942 off the coast of North Carolina during the Battle of the Atlantic. The shipwrecks are located in an area known as the “Graveyard of the Atlantic,” which includes sunken vessels from US and British naval fleets, merchant [...]

The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells, which are known to attack tumor cells and cells infected by viruses. The key player in this process is a cytotoxic T cell molecule which has been known for a long time and which scientists have [...]
