One step closer to nanobiorobots

August 21, 2014 11:51 pm | News | Comments

This small step towards creating efficient nanobiorobots opens up great vistas for further research, similar to the creation of the first nanobiocomputers and the creation of the first diodes and transistors, which resulted in the rapid development of electronic computers.

Engineers take major step toward photonic circuits

August 21, 2014 11:42 pm | News | Comments

Electrical engineering researchers at UAlberta are designing nano-optical cables small enough to replace the copper wiring on computer chips. This could result in radical increases in computing speeds and reduced energy use by electronic devices.

Solar energy that doesn't block the view

August 21, 2014 11:28 pm | News | Comments

Past efforts in the production of energy from solar cells have yielded poor results; the energy production was inefficient and the materials were highly-colored. MSU researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window.

NASA's RXTE satellite decodes the rhythm of an unusual black hole

August 21, 2014 12:09 am | News | Comments

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. By going over past RXTE observations, the astronomers found specific changes in brightness that helped them determine M82 X-1 measures around 400 solar masses.

Raytheon and UMass Lowell establish joint research facility for advanced materials

Promising ferroelectric materials reveal quirky habit

August 20, 2014 3:26 pm | News | Comments

Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics—materials that use built-in electric polarizations to read and write digital information, outperforming the magnets inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data.

Graphene rubber bands could stretch limits of healthcare

August 19, 2014 9:11 pm | News | Comments

Although body motion sensors already exist in different forms, they have not been widely used due to their complexity and cost of production. Researchers have for the first time treated common elastic bands with graphene, to create a flexible sensor that is sensitive enough for medical use and can be made cheaply.

Seven tiny grains captured by Stardust likely visitors from interstellar space

August 18, 2014 12:27 am | News | Comments

Since 2006, when NASA’s Stardust spacecraft delivered its aerogel and aluminum foil dust collectors back to Earth, a team of scientists has combed through the collectors in search of rare, microscopic particles of interstellar dust. The team now reports that they have found seven dust motes that probably came from outside our solar system, perhaps created in a supernova explosion millions of years ago and altered by eons.
