Researchers have a good idea what causes immune system changes on Earth— things like stress, inadequate sleep and improper nutrition. New research suggests that spaceflight may temporarily alter the immune system of crew members flying long-duration missions aboard the ISS.
A system proposed by researchers recycles materials from discarded car batteries— a potential source of lead pollution— into new, long-lasting solar panels that provide emissions-free power.
A new field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct research flights Aug. 28 through Oct. 1, covering the peak of summer sea ice melt.
Through commands, autonomous devices arranged selves into vast, complex shapes in the first 1,000-robot flash mob.
A student team has designed, built and tested a critical part of a new rocket engine as part of a NASA project to develop spacecraft technologies needed to land on the moon, Mars and other cosmic venues.
In the future, working up a sweat by exercising may not only be good for your health, but it could also power your small electronic devices. Researchers are reporting today that they have designed a sensor in the form of a temporary tattoo that can both monitor a person’s progress during exercise and produce power from their perspiration.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.
Bee, snake or scorpion venom could form the basis of a new generation of cancer-fighting drugs, scientists say. They have devised a method for targeting venom proteins specifically to malignant cells while sparing healthy ones, which reduces or eliminates side effects that the toxins would otherwise cause.
Location. Location. Location. The popular real estate mantra also turns out to be equally important for growing wine grapes in fields and storing bottles of the beverage at home or in restaurants, according to researchers. Those are just two of the topics that will be covered in a symposium on wine this week.
Researchers are using Wi-Fi to look through solid walls and see every square inch of what’s on the other side. Built into robots, the technology has far-reaching possibilities.
How do animals see? It’s a question that vexes biologists and fascinates anyone who has watched animals go about their business: what does the world look like through their eyes? Scientists are attempting to answer some of these fundamental questions by studying the success of bird and egg camouflage.
Tortoises have learned how to use touchscreens as part of a study that aimed to do so. A researcher gave tortoises treats, such as strawberries, when the reptiles looked at, approached and then pecked blue circles on the screen. Two of the tortoises went on to apply their knowledge to a real-life situation.
Engineers have fabricated a new elastic material coated with microscopic, hair like structures that tilt in response to a magnetic field. Depending on the field’s orientation, the micro-hairs can tilt to form a path through which fluid can flow.
Counterfeit drugs, which at best contain wrong doses and at worst are toxic, are thought to kill more than 700,000 people per year. To fight back against these and other forms of counterfeiting, researchers have developed a way to make labels that change when you breathe on them, revealing a hidden image.
Editors of photos routinely resize objects, or move them up, down or sideways. Now, researchers are adding an extra dimension to photo editing by enabling editors to turn or flip objects any way they want, even exposing surfaces not visible in the original photograph.
