The math says Red Sox have a big edge in the World Series

Posted: 23 Oct 2013 11:46 AM PDT

Now that the World Series is about to begin, a math professor has announced the probability of each of the contenders winning the best 4 out of 7 game contest. "The Boston Red Sox have a nearly 70 percent chance of winning the series", he says. But he gives the caveat that the St. Louis Cardinals have defeated both the competition and his mathematical model in each of their previous series.

Chemists use MRI to peek at temperatures of gases inside catalytic reactors

Posted: 23 Oct 2013 10:18 AM PDT

Chemists report a new "green chemistry" method that may have far-reaching applications. In a significant step toward improving the design of future catalysts and catalytic reactors, the chemists have developed a method to map the temperatures of reacting gases inside a catalytic reactor at the microscale.

Astronomers discover the most distant known galaxy: Galaxy seen as it was just 700 million years after Big Bang

Posted: 23 Oct 2013 10:18 AM PDT

Astronomers have discovered the most distant galaxy ever found. The galaxy is seen as it was just 700 million years after the Big Bang, when the universe was only about 5 percent of its current age of 13.8 billion years.

The reins of Casimir: Engineered nanostructures could offer way to control quantum effect

Posted: 23 Oct 2013 09:56 AM PDT

You might think that a pair of parallel plates hanging motionless in a vacuum just a fraction of a micrometer away from each other would be like strangers passing in the night -- so close but destined never to meet. Thanks to quantum mechanics, you would be wrong.

'Getting the edge' on photon transport in silicon

Posted: 23 Oct 2013 09:56 AM PDT

Scientists have a new way to edge around a difficult problem in quantum physics, now they have demonstrated how particles of light flow within a novel device.

Force to be reckoned with: Laser power measured with portable scale

Posted: 23 Oct 2013 09:56 AM PDT

Researchers have demonstrated a novel method for measuring laser power by reflecting the light off a mirrored scale, which acts as a force detector.

First-ever information systems job index shows healthy market for college students majoring in information systems

Posted: 23 Oct 2013 09:54 AM PDT

Despite a 7.2 percent national unemployment rate, the job market is a healthy one for college students majoring in information systems, with nearly three quarters of students receiving at least one job offer, according to the U.S. nationwide IS Job Index.

Development of novel robots funded to assist people with disabilities, aid doctors

Posted: 23 Oct 2013 09:54 AM PDT

As part of the National Robotics Initiative, NIH has awarded funding for three projects to develop the next generation of robots that work cooperatively with people.

Natural compound can be used for 3-D printing of medical implants

Posted: 23 Oct 2013 07:13 AM PDT

Biomedical engineering researchers have discovered that a naturally-occurring compound can be incorporated into three-dimensional printing processes to create medical implants out of non-toxic polymers. The compound is riboflavin, which is better known as vitamin B2.

How did supermassive black holes grow so big?

Posted: 23 Oct 2013 06:09 AM PDT

Galaxies may look pretty and delicate, with their swirls of stars of many colors -- but don't be fooled. At the heart of every galaxy, including our own Milky Way, lies a supermassive black hole.

Advanced light source provides a new look at vanadium dioxide

Posted: 23 Oct 2013 06:09 AM PDT

Researchers have taken a new look at vanadium dioxide, a correlated material that could be used to make energy-efficient ultrafast electronic switches.

How are Open Access publishing and Massive Open Online Courses disrupting the academic community?

Posted: 23 Oct 2013 06:09 AM PDT

Supporters of open academic content have long touted its ability to widen the impact and productivity of scholarship while relieving cost pressures in academia. While the development of open-access (OA) publishing and Massive Open Online Courses (MOOCs) have been labeled a disruption to publishing and the academic community, a new study finds that OA has a more tempered impact on scholarship while the impact of MOOCs on teaching is more severe.

Wood chips to biofuel in hours

Posted: 23 Oct 2013 06:08 AM PDT

Until now, it has taken weeks to make biofuel from trees. This slow pace has been a bottleneck for the industry. Researchers have now shortened the process to a few hours.

New radar system inspired by dolphins to detect hidden surveillance and explosive devices

Posted: 23 Oct 2013 06:08 AM PDT

Inspired by the way dolphins hunt using bubble nets, scientists have developed a new kind of radar that can detect hidden surveillance equipment and explosives. The twin inverted pulse radar (TWIPR) is able to distinguish true 'targets', such as certain types of electronic circuits that may be used in explosive or espionage devices, from 'clutter' (other metallic items like pipes, drinks cans, nails for example) that may be mistaken for a genuine target by traditional radar and metal detectors.

Mass producing pocket labs

Posted: 23 Oct 2013 06:07 AM PDT

There is certainly no shortage of lab-on-a-chip (LOC) devices, but in most cases manufacturers have not yet found a cost-effective way to mass produce them. Scientists are now developing a platform for series production of these pocket laboratories.

Intercepting asteroids to avoid Armageddon

Posted: 23 Oct 2013 06:07 AM PDT

Potential asteroid impact on Earth can have disastrous consequences. In order to prevent such collisions, earthbound space objects must be deflected. This could be accomplished using a space probe to impact the asteroid.
