Swirls in remnants of Big Bang may hold clues to universe's infancy

Posted: 13 Dec 2013 05:10 PM PST

South Pole Telescope scientists have detected for the first time a subtle distortion in the oldest light in the universe, which may help reveal secrets about the earliest moments in the universe's formation.

Engineers make strides toward artificial cartilage

Posted: 13 Dec 2013 10:55 AM PST

A research team has developed a better recipe for synthetic replacement cartilage in joints, calling for a newly designed durable hydrogel to be poured over a three-dimensional fabric "scaffold."

Clot-busters, caught on tape

Posted: 13 Dec 2013 10:53 AM PST

Ultrasound-stimulated microbubbles have been showing promise in recent years as a non-invasive way to break up dangerous blood clots. But though many researchers have studied the effectiveness of this technique, not much was understood about why it works. Now a team of researchers has collected the first direct evidence showing how these wiggling microbubbles cause a blood clot's demise.

POPUP: Novel organic solar cells

Posted: 13 Dec 2013 06:34 AM PST

Future solar cells will be light and mechanically flexible. They will be produced at low costs with the help of printing processes. Scientists aim at developing more efficient materials and new architectures for organic photovoltaic devices. They are working on improving the basic understanding and developing new architectures for semitransparent and non-transparent solar cells and modules.

Simple mathematical formula describes human struggles

Posted: 12 Dec 2013 03:59 PM PST

The world seems to be getting more complex every day -- some might say too complex. But what if every interaction, every potential conflict we have is really very simple and easy to understand? Mathematicians have found a mathematical formula demonstrating just that: the dynamics of every escalating conflict human beings find themselves in, from children who won't stop crying to international terrorism, can be explained rather easily.

Can we turn unwanted carbon dioxide into electricity?

Posted: 12 Dec 2013 03:59 PM PST

Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide underground -- and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.

First rock dating experiment performed on Mars

Posted: 12 Dec 2013 03:59 PM PST

Although researchers have determined the ages of rocks from other planetary bodies, the actual experiments -- like analyzing meteorites and moon rocks -- have always been done on Earth. Now, for the first time, researchers have successfully determined the age of a Martian rock -- with experiments performed on Mars. This work could not only help in understanding the geologic history of Mars but also aid in the search for evidence of ancient life there.

Low-power tunneling transistor for high-performance devices at low voltage

Posted: 12 Dec 2013 01:03 PM PST

A new type of transistor that could make possible fast and low-power computing devices for energy-constrained applications such as smart sensor networks, implantable medical electronics and ultra-mobile computing is feasible, according researchers. Called a near broken-gap tunnel field effect transistor, the new device uses the quantum mechanical tunneling of electrons through an ultra-thin energy barrier to provide high current at low voltage.

Using air transportation data to predict pandemics

Posted: 12 Dec 2013 11:21 AM PST

Computational work has led to a new mathematical theory for understanding the global spread of epidemics. The resulting insights could not only help identify an outbreak's origin but could also significantly improve the ability to forecast the global pathways through which a disease might spread. Scientists could use the theory to reconstruct outbreak origins with higher confidence, compute epidemic spreading speed and forecast when an epidemic wave front is to arrive at any location worldwide.

Helping cancer researchers make sense of deluge of genetic data

Posted: 12 Dec 2013 11:19 AM PST

A web research tool is helping cancer researchers and physicians make sense out of genetic data from nearly 100,000 patients and more than 50,000 mice. The Gene Expression Barcode 3.0 is a vital resource in the new era of personalized medicine.
