By using swarms of untethered grippers, each as small as a speck of dust, Johns Hopkins engineers say they have devised a new way to perform biopsies that could provide a more effective way to access narrow conduits in the body.
Researchers at the University of Illinois have developed new micro batteries that out-power even the best supercapacitors and could drive new applications in compact electronics.
Scientists at NCAR find that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.
A research team at the University of Southern California has developed a way to encrypt a crucial portion of the photo to keep it secure, while leaving enough unencrypted that it can still be utilized by cloud filesharing services.
Even in the face of a disaster, we remain optimistic about our chances of injury compared to others, according to a study by the Society for Personality and Social Psychology.
An international research team led by Oklahoma State University decoded the genetic information in Galdieria to understand how the one-celled alga acquired its flexibility and resilience.
Scientists at Northwestern University have identified conditions and properties that power companies can consider using to keep power generators in a desired synchronized state and help make a self-healing power grid a reality.
Using underwater video cameras to record fish feeding on South Pacific coral reefs, Georgia Tech scientists found that fish can be picky eaters--a trait that could spell trouble for endangered reef systems.
The U.S. Food and Drug Administration has granted market approval to an artificial retina technology, the first bionic eye to be approved for patients in the U.S.
Scientists from NCAR, UCSD, Scripps and Florida State concluded that the heat generated by everyday activities in metropolitan areas alters the character of the jet stream and other major atmospheric systems.
Researchers at North Carolina State University have devised a technique to embed needle-like carbon nanofibers in an elastic membrane, creating a flexible "bed of nails" on the nanoscale that opens the door to development of new drug-delivery systems.
Scientists from Michigan State University and the Chinese Academy of Sciences forecast how a changing climate may affect the most common species of bamboo that carpets the forest floors of prime panda habitat in northwestern China.
Researchers at the University of Illinois and UC San Diego have discovered a new compound that restores the health of mice infected with MRSA, an otherwise dangerous bacterial infection.
People are able to detect, within a split second, if a hurtful action they are witnessing is intentional or accidental, new research on the brain at the University of Chicago shows.
Scientists at the University of Utah uncover how insects domesticate bacteria after a man, who was cutting down a tree, cut his hand and then sought medical help.
Scientists at the Georgia Institute of Technology have found evidence that when corals are under attack by toxic seaweed they do what anyone might do when threatened--they call for help.
Decades of extreme weather crippled, and ultimately decimated, first the political culture and later the human population of the ancient Maya, according to a study by an interdisciplinary team of researchers from UC Davis, Penn State and Switzerland.
A chemistry professor at Princeton University has developed a process that allows ordinary iron to be used as a substitute catalyst in certain reactions that up till now have required precious metals.
Researchers at the Ohio State University and the University of Cincinnati have discovered why plants and animals had a hard time recovering from the largest mass extinction in Earth's history 250 million years ago.
An insect's internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.
A study by Harvard University researchers finds that when it comes to the health of forests, native plants and wildlife, the best management decision may be to do nothing.
Scientists at the University of Akron discover that spiders' design mastery allows them to create webs that stick to the ground and to elevated surfaces differently.
Research from Cornell University indicates that getting rid of insects could trigger some unwelcome ecological consequences, such as the rapid loss of desired traits in plants, including their good taste and high yields.
Researchers from Rice University have created a multi-antenna technology that could help wireless providers keep pace with the voracious demands of data-hungry smartphones and tablets.
Researchers at Oregon State University for the first time have confirmed some of the mechanisms by which overfishing and nitrate pollution can contribute to the destruction of coral reefs.
Johns Hopkins researchers have created a synthetic protein that, when activated by ultraviolet light, can guide doctors to places within the body where cancer, arthritis and other serious medical disorders can be detected.
Scientists at UMass-Amherst report the discovery of an antibacterial coating for surgical sutures that is almost 1,000 times more effective than the most widely used commercial coating.
