Male-biased tweeting

April 23, 2014 1:14 pm | by EurekAlert! | Comments

It all started out with a comic strip in 1985. A cartoon character explained to her female companion which three requirements a movie had to fulfil for her to want to watch it: (one) it has to have at least two women in it (two) who talk to each other about (three) something besides a man....

Steering chemical reactions with laser pulses

April 23, 2014 1:13 pm | by EurekAlert! | Comments

Usually, chemical reactions just take their course, much like a ball rolling downhill. However, it is also possible to deliberately control chemical reactions: at the Vienna University of Technology, molecules are hit with femtosecond laser pulses, changing the distribution of electrons in the molecule....

A key to enjoying massive online photo files may be giving up some control

April 23, 2014 1:10 pm | by EurekAlert! | Comments

The ability of individuals to store and instantly access thousands of their photos online has become a commonplace luxury, but the sheer size of these archives can be intimidating. Researchers at Carnegie Mellon University and Microsoft Research Cambridge, UK, have found people might actually enjoy their collections more....

Research shows impact of Facebook unfriending

April 23, 2014 1:08 pm | by EurekAlert! | Comments

Two studies from the University of Colorado Denver are shedding new light on the most common type of `friend' to be unfriended on Facebook and their emotional responses to it. The studies, published earlier this year, show that the most likely person to be unfriended is a high school acquaintance....

Nanoreporters tell 'sour' oil from 'sweet'

April 23, 2014 1:06 pm | by EurekAlert! | Comments

Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they're still in the ground. The nanoreporter is based on nanometer-sized carbon material....

Halving hydrogen

April 23, 2014 11:13 am | by Pacific Northwest National Laboratory | Comments

Like a hungry diner ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast. The view confirms previous hypotheses and...

Physicists consider implications of recent revelations about the universe's first light

April 23, 2014 10:05 am | by EurekAlert! | Comments

Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. This almost unimaginably fast expansion was first theorized more than three decades ago, yet only now has "smoking gun" proof emerged....

Liquid spacetime

April 23, 2014 10:01 am | by EurekAlert! | Comments

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of these models predict that spacetime at the Planck scale (10-33cm) is no longer continuous....

Attacks on payment systems trail other cybercrimes

April 23, 2014 9:57 am | by BREE FOWLER, AP Technology Writer | Comments

While the theft of millions of credit card numbers from Target customers last year drew attention to Internet crime, a new study finds that breaches of retail payment systems are less common than other kinds of attacks. A report from Verizon found that Internet attacks...

UN study: Cellphones can improve literacy

April 23, 2014 9:54 am | Comments

A study by the U.N. education agency says cellphones are getting more and more people to read in countries where books are rare and illiteracy is high. Paris-based UNESCO says 774 million people worldwide cannot read, and most people in sub-Saharan Africa don't own any books....

Irrational fears

April 23, 2014 2:12 am | by MIT Technology Review | Comments

We should think sensibly about nuclear energy’s risks.climate scientists have consistently demonstrated how important it will be to drastically reduce human-­generated carbon emissions. Yet almost no progress has been made. Hydroelectric power is reliable and cheap, but there aren’t enough suitable...

Perspective on 10 breakthrough technologies

April 23, 2014 2:12 am | by MIT Technology Review | Comments

In this issue of the magazine, Brian Bergstein, MIT Technology Review’s deputy editor, interviewed Sarah Lewis, a curator, about the “accomplishments that come from seemingly improbable circumstances and the connections between art and science” (see “Q&A: Sarah Lewis”). Asked about Samuel...

Diamond teleporters herald new era of quantum routing

April 22, 2014 5:12 pm | by MIT Technology Review | Comments

The ability to teleport quantum information between diamond crystals that can also store it is a small but important step toward a quantum Internet.The prospect of a quantum Internet has excited physicists for two decades. A quantum Internet will allow the transmission of information around the...

Robotic mouse could help solve cat obesity problem

April 22, 2014 4:15 pm | by University of Illinois | Comments

Dave Cohen, a University of Illinois PhD student in the department of electrical and computer engineering (ECE), is leading a group that has built the initial prototype for Mousr, a robotic pet for your cat that can sense the movements of your cat and react the way...

RNA shows potential as boiling-resistant anionic polymer material for nanoarchitectures

April 22, 2014 2:30 pm | by EurekAlert! | Comments

A team of nanotechnology researchers at the University of Kentucky has discovered new methods to build heat resistant nanostructures and arrays using RNA. The research, led by Peixuan Guo, professor and William Farish Endowed Chair in Nanobiotechnology at the UK College of Pharmacy and Markey Cancer Center...
