NASA's Spitzer Space Telescope witnesses asteroid smashup Posted: 28 Aug 2014 02:01 PM PDT NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.

Astronomy: Radio telescopes settle controversy over distance to Pleiades Posted: 28 Aug 2014 11:27 AM PDT A worldwide network of radio telescopes measured the distance to the famous star cluster the Pleiades to an accuracy within 1 percent. The result resolved a controversy raised by a satellite's measurement that now is shown to be wrong. The incorrect measurement had challenged standard models of star formation and evolution.

Global warming pioneer calls for carbon dioxide to be taken from atmosphere and stored underground Posted: 28 Aug 2014 08:09 AM PDT Wally Broeker, the first person to alert the world to global warming, has called for atmospheric carbon dioxide to be captured and stored underground.

Synthesis produces new fungus-derived antibiotic Posted: 28 Aug 2014 08:09 AM PDT A fortuitous collaboration has led to the total synthesis of a recently discovered natural antibiotic. The laboratory recreation of a fungus-derived antibiotic, viridicatumtoxin B, may someday help bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.

Quantum physics enables revolutionary imaging method Posted: 28 Aug 2014 08:08 AM PDT Researchers have developed a fundamentally new quantum imaging technique with strikingly counter-intuitive features. For the first time, an image has been obtained without ever detecting the light that was used to illuminate the imaged object, while the light revealing the image never touches the imaged object.

Avatars make the Internet sign to deaf people Posted: 28 Aug 2014 06:12 AM PDT It is challenging for deaf people to learn a sound-based language, since they are physically not able to hear those sounds. Hence, most of them struggle with written language as well as with text reading and comprehension. Therefore, most website content remains inaccessible for them. Computer scientists want to change the situation by means of a method they developed: animated online characters display content in sign language. In the long term, deaf people would be able to use the technique to communicate on online platforms via sign language.

Spot light on tailor-made multicyclic type of polymers Posted: 27 Aug 2014 06:37 PM PDT Scientists have synthesized multicyclic type of polymers for the first time offering insights for tailoring polymer properties as well as the mathematics of complex geometries.

Industrial management: Avoiding alarms Posted: 27 Aug 2014 06:37 PM PDT An intelligent system that predicts when alarms might be triggered could greatly improve the management of industrial plants.

Materials: Cubic cluster chills out Posted: 27 Aug 2014 06:37 PM PDT A gadolinium-based material that can be cooled by varying a magnetic field may be useful for cooling low-temperature sensors.

A touching story: Ancient conversation between plants, fungi and bacteria Posted: 27 Aug 2014 01:33 PM PDT The mechanical force that a single fungal cell or bacterial colony exerts on a plant cell may seem vanishingly small, but it plays a heavy role in setting up some of the most fundamental symbiotic relationships in biology, according to a new study. It's known that disease-causing fungi build a structure to break through the plant cell wall, "but there is growing evidence that fungi and also bacteria in symbiotic associations use a mechanical stimulation to indicate their presence," says one researcher. "They are knocking on the door, but not breaking it down."
