New Georgia Tech research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they're able to spread. The findings, which are published in the journal PLoS One, found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have created a Robot Scientist which the researchers believe is the first machine to have independently discovered new scientific knowledge.
Physicists at the University of Vienna and the Austrian Academy of Sciences have achieved quantum teleportation over a record distance of 143 km. The experiment is a major step towards satellite-based quantum communication. The results have now been published in "Nature"
The majority of public high school biology teachers are not strong classroom advocates of evolutionary biology, despite 40 years of court cases that have ruled teaching creationism or intelligent design violates the Constitution, according to Penn State political scientists. A mandatory undergraduate course in evolutionary biology for prospective teachers, and frequent refresher courses for curren
Earth's climate is strongly influenced by the presence of particles of different shapes and origins -- in the form of dust, ice and pollutants -- that find their way into the lowest portion of the atmosphere, the troposphere. There, water adsorbed on the surface of these particles can freeze at higher temperatures than pure water droplets, triggering rain and snow.

Some baseball superstitions are accepted as cold, hard truth. But in the world of physics, the most accepted verities are subject to experimentation. A corked bat hits the ball further? Not in Lloyd Smith's lab.
The largest snake the world has ever known -- as long as a school bus and as heavy as a small car -- ruled tropical ecosystems only 6 million years after the demise of the fearsome Tyrannosaurus rex, according to a new discovery published in the journal Nature.
It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters' "miracle solvents" to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness.
Hummer drivers believe they are defending America's frontier lifestyle against anti-American critics, according to a new study in the Journal of Consumer Research.
A pair of Johns Hopkins and government scientists have discovered that when jazz musicians improvise, their brains turn off areas linked to self-censoring and inhibition, and turn on those that let self-expression flow.
Religious leaders have contended for millennia that burning incense is good for the soul. Now, biologists have learned that it is good for our brains too.
Children with the genetic condition known as Williams syndrome have unusually friendly natures because they lack the sense of fear that the rest of us feel in many social situations.
Millions of computer users collectively transcribe the equivalent of 160 books each day with better than 99 percent accuracy, despite the fact that few spend more than a few seconds on the task and that most do not realize they are doing valuable work, Carnegie Mellon University researchers reported today in Science Express.
New imaging research shows that brain activity differs in sleep-deprived and well-rested people. The study, in the May 21 issue of The Journal of Neuroscience, shows that individuals who are sleep-deprived experience periods of near-normal brain function, but these periods are interspersed with severe drops in attention and visual processing.
Institute of Medical Biology (IMB) scientists under the Agency of Science, Technology and Research (A*STAR) in Singapore are part of an international team of researchers [1]who became the first in the world to discover the gene behind a rare skin cancer which grows rapidly for a few weeks before healing spontaneously, according to research published in Nature Genetics [2] today.

Composite and 3-D-printed components will mean jet engines that use 15 percent less fuel.A new generation of engines being developed by the world’s largest jet engine maker, CFM (a partnership between GE and Snecma of France), will allow aircraft to use about 15 percent less fuel—enough to save about $1 million per year per airplane and significantly reduce carbon emissions.

NASA's venerable Mars rover Opportunity has overcome a glitch that put the robot into standby mode late last month, agency officials announced Wednesday."The Opportunity rover is back under ground control, executing a sequence of commands sent by the rover team," NASA officials wrote in a mission update today. "Opportunity is no longer in standby automode and has resumed...
