Understanding and predicting solar flares

Posted: 23 Oct 2014 10:16 AM PDT

Scientists have identified a key phenomenon in the triggering of solar flares. Using satellite data and models, the scientists were able to monitor the evolution of the solar magnetic field in a region with eruptive behavior. Their calculations reveal the formation of a magnetic rope1 that emerges from the interior of the Sun and is associated with the appearance of a sunspot. They show that this structure plays an important role in triggering the flare.

Precise, programmable biological circuits

Posted: 23 Oct 2014 07:07 AM PDT

Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers. Bio-engineers will literally be able to program in future."

RF heating of magnetic nanoparticles improves thawing of cryopreserved biomaterials

Posted: 23 Oct 2014 07:07 AM PDT

Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Reserachers leverage a clinically proven technology platform, in magnetically heated nanoparticles, to overcome this major hurdle limiting further advancement in the field of cryopreservation.

Recent space debris threat warded off

Posted: 23 Oct 2014 06:20 AM PDT

Space debris, also known as 'space junk,' is an ongoing real-life concern for teams managing satellites orbiting Earth, including NOAA-NASA's Suomi National Polar-orbiting Partnership satellite. It is not unusual for satellites that have the capability of maneuvering to be repositioned to avoid debris or to maintain the proper orbit.

Moving in the quantum world

Posted: 23 Oct 2014 06:18 AM PDT

Simulating the behavior of a single particle can be quite a challenging task in physics; after all, it is microscopic and we usually cannot watch in real time. It becomes even more complicated when you realize that the particle has to follow the laws of quantum physics, which allow it be in two or more places at the same time through a phenomenon called superposition. Understanding how a quantum particle behaves is necessary to enhance our fundamental understanding of the laws of physics.

The perfume of the comet

Posted: 23 Oct 2014 06:18 AM PDT

How does a comet smell? Since early August the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) is sniffing the fumes of the comet Churyumov-Gerasimenko with its two mass spectrometers. The detected chemistry in the coma of the comet is surprisingly rich already at more than 400 million kilometers from the Sun.

Should the Japanese give nuclear power another chance?

Posted: 23 Oct 2014 06:07 AM PDT

On September 9, 2014, the Japan Times reported an increasing number of suicides coming from the survivors of the March 2011 disaster. In Minami Soma Hospital, which is located 23 km away from the power plant, the number of patients experiencing stress has also increased since the disaster. What's more, many of the survivors are now jobless and therefore facing an uncertain future.

Unexpected benefits of adjustable rate mortgages

Posted: 22 Oct 2014 09:35 AM PDT

As would be expected during a time of consumer deleveraging, households applied more than 70 percent of their mortgage savings to reducing outstanding credit card debts. Not only did the lower payments reduce mortgage defaults but credit card delinquencies fell. 'These choices had significant impact on foreclosures, house prices and employment in regions that were more exposed to interest rate declines,' the researchers concluded.

Posted: 22 Oct 2014 09:30 AM PDT

A prototype Rapid Adaptive Zoom for Assault Rifles (RAZAR) has been developed. At the push of a button, RAZAR can toggle between high and low magnifications, enabling users to zoom in without having to remove their eyes from their targets or their hands from their rifles. The RAZAR prototype uses a patented active optical zoom system, called "adaptive zoom."

Cyber protection developed for supply chains

Posted: 21 Oct 2014 06:07 PM PDT
