Heating a sheet of plastic may not bring it to life– but it sure looks like it does in new experiments. And, materials that can change their shape based on environmental conditions are useful for optics, three-dimensional biological scaffolds and the controlled encapsulation and release of drugs.
A type of male fish that builds sandcastles to impress females and intimidate rivals has provided an important clue about the evolution of new species.
“Here’s some of the stories trending This Week at NASA!” ISON update With a more than ninety percent probability that Comet ISON broke apart from a major heating event on its approach to the sun Thanksgiving Day, the search is on for what’s left of it. NASA will use a variety of space and Earth based telescopes to monitor the comet over the next several weeks, before the fate of ISON can be confirmed.
Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to us by smelling the carbon dioxide we exhale, being capable of tracking us down even from a distance. New research has found a key target that could be useful to disrupt host-seeking behavior and thus aid in the control of disease transmission.
Researchers have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules.
The engineering feat that enables a device to jolt a dangerously misbehaving heart back to its normal rhythm and save millions of lives is featured in a new video.
A combination of pop songs, talkback radio and cutting-edge science has enabled astronomers to identify a way to prevent catastrophic, multi-billion dollar space junk collisions.
Scientists have advanced a magnetic resonance imaging technology that may provide a breakthrough for screening liquids at airport security.
“Dealing with a buggy situation in the air …” “A next generation weather satellite is a step closer to launch …” “And a comet’s close encounter with the Sun … Those are some of the stories trending, This Week at NASA!” ISON and the Sun
Observers definitely saw Comet ISON brighten and change in November. If the comet survives perihelion— its closest approach to the sun— it will be visible both before dawn and after sunset this December.
Researchers have developed a way to heal gaps in wires too small for even the world’s tiniest soldering iron.
ESA’s three-satellite Swarm constellation has a four year mission. It will monitor Earth’s magnetic field, from the depth of our planet’s core to the heights of its upper atmosphere.
