The magnetic field in the center of the Milky Way is at least 10 times stronger than the rest of the galaxy, according to new research.

Many people have traded in their gas-guzzling old “clunkers” for newer and more efficient models or cut back on energy use at home by opting for Energy Star appliances and compact fluorescent light bulbs. But, when it comes to our muscles, a little less efficiency might be just what the doctor ordered, suggests new research.

Unlike Hawaii and other island groups, no native bird has gone extinct in the Galapagos Islands, although some are in danger. Biologists have found that finches — the birds Darwin studied — develop antibodies against two parasites that moved to the Galapagos, suggesting the birds can fight the alien invaders.
A team of researchers is being recognized for devising a new way to study a human protein that long has evaded close scrutiny by scientists investigating its role in the communication of important genetic messages inside a cell’s nucleus to workhorse molecules found elsewhere.
A breakthrough in discovering new millisecond pulsars is providing astronomers a greatly improved capability to use those natural cosmic tools to make the first direct detections of gravitational waves.

Why do we chew our food? Research has shown that it is not, as has long been presumed, to make chunks of food small enough to swallow without choking. Biomechanics, who have modelled the cohesive strength of food after a certain amount of chewing, have shown that we actually chew our food to ensure it [...]

The millions of people who spend hours every day on a cell phone may have a new excuse for yakking. A new indicates long-term exposure to electromagnetic waves emitted by cell phones may protect against and reverse Alzheimer’s disease.

Researchers report that Helicobacter pylori, the only bacterium known to survive in the harsh environment of the human stomach, directly activates an enzyme in host cells that has been associated with several types of cancer, including gastric cancer.

In two new videos from NASA’s Deep Impact spacecraft, bright flashes of light known as sun glints act as beacons signaling large bodies of water on Earth. These observations give scientists a way to pick out planets beyond our solar system (extrasolar planets) that are likely to have expanses of liquid, and so stand a [...]

A team of researchers has now determined in rodents how congestive heart failure triggers substantive changes to the nerves that control heart function.
