Teen sexting, the gender gap

Thu, 03/14/2013 - 16:49
A survey of US adolescents reveals a gender gap in attitudes towards sexting and perceived harm.

Is technology really too fast for society?

Thu, 03/14/2013 - 16:43
We often hear that technology is advancing so fast that society cannot keep up. But in reality, social change is intimately linked to technology changes, and that expectations of what technology can bring changes in intensity.

International gender difference in math and reading scores persists regardless of gender equality

Thu, 03/14/2013 - 15:18
Even in countries with high gender equality, sex differences in math and reading scores persisted in the 75 nations examined by a new study. Girls consistently scored higher in reading, while boys got higher scores in math, but these gaps are linked and vary with overall social and economic conditions of the nation.

Bootstrapping biotechnology: Engineers cooperate to realize precision grammar for programming cells

Thu, 03/14/2013 - 15:18
DNA sequences and statistical models have been unveiled that greatly increase the reliability and precision by which microbes can be engineered.

New research discovers the emergence of Twitter 'tribes'

Thu, 03/14/2013 - 12:50
Linguists have found evidence of how people form into tribe-like communities on social network sites such as Twitter.

Electrons behaving like a particle and a wave: Feynman's double-slit experiment brought to life

Thu, 03/14/2013 - 01:40
The precise methodology of Richard Feynman's famous double-slit thought-experiment -- a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave -- has been followed in full for the very first time.

Video game 'exercise' for an hour a day may enhance certain cognitive skills

Wed, 03/13/2013 - 22:21
Playing video games for an hour each day can improve subsequent performance on cognitive tasks that use similar mental processes to those involved in the game, according to new research.

A numerical simulation predicts the behavior of a component that controls light for faster computing.

Information technology: Improving the health of machines

Wed, 03/13/2013 - 15:17
Electronic engineers have developed and successfully tested a management system that increases the efficiency of wireless sensor networks for monitoring machine health.

Signal processing: Look-up tables to shoulder the processing load

Wed, 03/13/2013 - 15:16
Computing tasks for signal processing could be performed more quickly with less power by using look-up tables.

High-resolution endoscope as thin as a human hair

Wed, 03/13/2013 - 14:04
Engineers have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs. The advance could lead to an era of needle-thin, minimally invasive endoscopes able to view features out of reach of today's instruments.

Predictive Analysis: New generation of computational intelligence systems

Wed, 03/13/2013 - 13:55
Large parts of our lives are now being monitored and analysed by computers. Log on to Amazon and intelligent data analysis software can recommend a selection of books you might like to read. Far from being a sinister intrusion into people's privacy, the purpose of these systems is to improve our lives, experts say.

Open software platform to bring down energy costs

Wed, 03/13/2013 - 13:54
Energy is getting more and more expensive, and experts are predicting record electricity and heating prices. A software platform promises to lighten the load for households and businesses by making it easier for consumers to put renewables to good effect.

Quantum magnets moving along: Scientists observes coherent propagation of a single spin impurity in a chain of ultracold atoms

Wed, 03/13/2013 - 13:54
Many discoveries in physics came as a big surprise -- for example the phenomenon, that some materials loose almost all their electrical resistance at low temperatures, or that others become superconductors at unexpectedly high temperatures. In the past it was mainly due to theoreticians to develop models explaining these unusual properties. Unfortunately it is not possible to have a direct look into a solid state crystal and follow up the motion of charge carriers as this process happens at extremely short time and length scales. Scientists have now observed the coherent propagation of single spin excitations in an ultracold quantum gas of strongly correlated atoms.

Hiding secret messages in email jokes

It is possible to hide secret messages in simple jokes, according to new research.

Ultra-high-speed optical communications link sets new power efficiency record

Tue, 03/12/2013 - 17:46
Ultrafast supercomputers that operate at speeds 100 times faster than current systems are now one step closer to reality. Researchers have found a way to transmit massive amounts of data with unprecedentedly low power consumption.

New automated process simplifies alignment and splicing of multicore optical fibers

Tue, 03/12/2013 - 17:46
New multicore optical fibers have many times the signal-carrying capacity of traditional single-core fibers, but their use in telecommunications has been restricted because of the challenge in splicing them together. Now, a new technique offers an automated method for aligning and splicing multicore fibers, allowing engineers to take manual splicing out of the lab and into an automated production line.

New distance record for 400 Gb/s data transmission

Tue, 03/12/2013 - 17:46
Scientists have devised a new patent-pending technique enabling 400 Gb/s signals to be sent over today's 100 gigahertz-grid optical networks over ultra-long distances for the first time.
