Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals. The crystals can pump or extract heat, even on the nanoscale, so they could be used on computer chips to prevent overheating or even meltdown, which is currently a major limit to higher computer speeds.
Over the last decade there has been an increased interest in developing resonators for gravitmetric sensing; however, the sensors' response to variations in temperature has prevented them from being used outside the laboratory. New sensors developed by researchers at the University of Cambridge negate the effects of temperature so that they may be used in industries including health care, telecommunications and environmental monitoring.
Scientists have introduced a new method developed specifically for use on paper. It produces a 'negative' of the fingerprint and is, in contrast to conventional methods, independent of the composition of the sweat residue left behind.
Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology.
Vortex-Strahlen, die wie ein Wirbelsturm rotieren, bieten völlig neue Möglichkeiten für die Elektronenmikroskopie. An der TU Wien wurden eine Möglichkeit entdeckt, extrem intensive Vortexstrahlen zu erzeugen.
Pratibha L. Gai, a former adjunct professor of materials science at the University of Delaware, has been selected to receive the L'Oreal-UNESCO Women in Science award for excellence in the physical sciences.
Weill Cornell Medical College announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill and Melinda Gates Foundation. Researchers at Weill Cornell have been awarded three research grants totaling more than $1.5 million. Weill Cornell's Dr. Juan R. Cubillos-Ruiz, a postdoctoral research associate in medicine in the laboratory of Dean Dr. Laurie H. Glimcher, will pursue an innovative global health and development research project titled, "Tailored Nanodevices to Understand Resistance Against HIV".
A University of Cincinnati cancer biology team reports breakthrough findings about specific cellular mechanisms that may help overcome endocrine (hormone) therapy-resistance in patients with estrogen-positive breast cancers, combating a widespread problem in effective medical management of the disease.
At the Electronica 2012 trade fair, Fraunhofer researchers will present a printed thermogenerator, which in the future will be able to generate energy supply for sensors through temperature differences.
The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers to date.
Scientists have found through spectroscopic investigations on a hydrogen-producing enzyme that the environment of the catalytic site acts as an electron reservoir in the enzyme. Thus, it can very efficiently produce hydrogen, which has great potential as a renewable energy source.
