By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a va

The level of immunity to the recently circulating H7N9 influenza virus in an urban and rural population in Vietnam is very low, according to the first population level study to examine human immunity to the virus, which was previously only found in birds. The findings have implications for planning the public health response to this pandemic threat.

A new analysis shows that the nation's land and water resources could likely support the growth of enough algae to produce up to 25 billion gallons of algae-based fuel a year in the United States, one-twelfth of the country's yearly needs.

Environment is not the only factor in shaping regulatory patterns -- and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

Australian scientists have charted the path of insulin action in cells in precise detail like never before. This provides a comprehensive blueprint for understanding what goes wrong in diabetes.

Northwestern University researchers have developed a new method for delivering molecules into single, targeted cells through temporary holes in the cell surface. The technique could find applications in drug delivery, cell therapy, and related biological fields.

Nowadays, the most diverse species of crocodile are found in northern South America and Southeast Asia: As many as six species of alligator and four true crocodiles exist, although no more than two or three ever live alongside one another at the same time. It was a different story nine to about five million years ago, however, when a total of 14 different crocodile species existed and at least sev

Rapid climate change during the Middle Stone Age, between 80,000 and 40,000 years ago, during the Middle Stone Age, sparked surges in cultural innovation in early modern human populations, according to new research.

Scientists discovered a new enigmatic species of ant coming from the Philippines. Cardiocondyla pirata or the pirate ant engages the imagination with a bizarre pigmentation pattern that has no equivalent worldwide. The female castes in the colonies of these species can be recognized by a distinctive dark stripe across the eyes that resembles a pirate eye patch, which inspired the authors to

Biologists have known for a long time that some creatures evolve more quickly than others. Exactly why isn't well understood, particularly for plants. But it may be that height plays a role, says Robert Lanfear of Australian National University and the U. S. National Evolutionary Synthesis Center.
The mighty T. rex may have thrashed its massive head from side to side to dismember prey, but a new study shows that its smaller cousin Allosaurus was a more dexterous hunter and tugged at prey more like a modern-day falcon.

As weather warms up off the coast of France, blooms of plankton have once again begun to form, creating a beautiful, multicolored swirl visible from space.NASA's Terra and Aqua satellites acquired these images of the colorful blooms on April 20 and May 4, according to the NASA Earth Observatory. On the later date, a noticeably larger bloom occurred, fueled by nutrient ru...
A largely forgettable rainfall provoked a growth in vegetation that, followed by a hot, near-record dry period, simply resulted in more fuel for potential wildfires.When it comes to Southern California's increasingly perilous fire season, you can blame both the lack of rain and the little rain we did have.
The appeal of owning your own property — and all the private goods that came with it — may have convinced nomadic humans to settle down and take up farming. So says a new study that tried to puzzle out why early farmers bothered with agriculture.
Douglas Trumbull's new project would use fast frame rates, huge screens, 4K digital for an "immersive" experience. Are audiences ready?
Chris Hadfield has conquered space. Now he's conquering the Internet, too.
Neuroscientist Henry Markram says he can build a supercomputer replica of the human brain. Now he has $1.3 billion to prove it.
Hospitals hoping to attract patients and build goodwill are teaming up with medical-screening companies to promote tests they say might prevent deadly strokes or heart disease. What their promotions don’t say is that an influential government panel recommends against many of the tests for people without symptoms or risk factors.
I detest household bugs. Abhor them. There isn’t a word strong enough to describe how I feel about bugs in my home. That hatred provokes guilt, because I fancy myself an environmentalist. As such, I’m supposed to feel a kinship with all creatures. We’re connected in a circle of life, a colorful tapestry, a delicate web of interdependence.
Bodily waste is widely considered a topic not to be discussed in polite company; it’s something to be flushed and forgotten. But a new book argues that waste, in all its human and animal forms, is worth getting to know intimately
Bacteria that live in the gut have been used to reverse obesity and Type-2 diabetes, animal studies show.
Vast reserves of shale oil is set to make the US an exporter rather than a leading importer, delivering a blow to Middle East oil producers that can expect to see demand fall, an International Energy Agency report observes.
The Sun has unleashed the most powerful eruption - a solar flare - of 2013 so far.
