Finding the statistical fingerprints of election thieves

Posted: 25 Sep 2012 12:21 PM PDT

Scientists examined voter data from a dozen recent elections around the world and found statistical evidence for election fraud in two of them.

New tool for CSI? Geographic software maps distinctive features inside bones

Posted: 25 Sep 2012 11:39 AM PDT

A common type of geographic mapping software offers a new way to study human remains. In a new study, researchers describe how they used commercially available mapping software to identify features inside a human foot bone -- a new way to study human skeletal variation.

Lab encodes collagen: Program defines stable sequences for synthesis, could help fight disease, design drugs

Posted: 25 Sep 2012 11:37 AM PDT

In a discovery with implications for drug design, tissue engineering and the treatment of disease, researchers have created a program to encode self-assembling collagen proteins.

Best constraint on mass of photons, using observations of super-massive black holes

Posted: 25 Sep 2012 11:26 AM PDT

A global team of scientists has determined the best constraint on the mass of photons so far, using observations of super-massive black holes. The researchers found a way to use astrophysical observations to test a fundamental aspect of the Standard Model -- namely, that photons have no mass -- better than anyone before.

Farthest ever view of the universe assembled by combining 10 years of NASA Hubble Space Telescope photographs

Posted: 25 Sep 2012 11:25 AM PDT

Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of humankind's deepest-ever view of the universe. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full Moon.

Intuitive visual control provides faster robot operation

Posted: 25 Sep 2012 11:25 AM PDT

Using a novel method of integrating video technology and familiar control devices, a research team is developing a technique to simplify remote control of robotic devices.

Oscillating microscopic beads could be key to biolab on a chip

Posted: 25 Sep 2012 07:27 AM PDT

Researchers have found a way to manipulate and measure magnetic particles without contact, potentially enabling multiple medical tests on a tiny device.

Emotion detector enables design of tailor-made election campaigns

Posted: 25 Sep 2012 06:16 AM PDT

Messages, attires, gestures, themes or melodies that are liked by the public are some of the aspects that guarantee the success of a political party. Researchers are now helping to define such feelings thanks to Sentient, a "feelings detector". This device issues reports on the positive or negative perception of some people to the stimuli of their environment.  Thus, Sentient provide campaign managers with the necessary information to determine, adjust or even enhance the elements influencing voters' intentions.

Burying the hatchet in the laser lab

Posted: 25 Sep 2012 06:15 AM PDT

Experts have been heavily discussing why exactly electrically insulating materials insulate as they do. Based on different mechanisms, a classification scheme for insulators has been in use since the 1960s -- a theoretical one. However, it has been yet impossible to distinctly classify all insulators due to a lack of suitable experimental approaches. A team of physicists has now developed a new method to distinguish different insulators unambiguously.

Fast algorithm extracts and compares document meaning

Posted: 25 Sep 2012 06:15 AM PDT

A computer program could compare two documents and work spot the differences in their meaning using a fast semantic algorithm developed by information scientists in Poland.

Novel materials become multifunctional at ultimate quantum limit

Posted: 25 Sep 2012 06:13 AM PDT

Physicists have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop unusual magnetic properties.

Mars-like places on Earth give new insights into Rover data and conditions for life

Posted: 24 Sep 2012 11:27 AM PDT

Life thrives on Planet Earth. In even the most inhospitable places – the freezing Antarctic permafrost, sun-baked saltpans in Tunisia or the corrosively acidic Rio Tinto in Spain – pockets of life can be found. Some of these locations have much in common with environments found on Mars, as discovered by orbiters and rovers exploring the surface. Researchers have made a series of field trips to the most Mars-like places on Earth.

Windshield wiper for Mars dust developed: Actuator moved by materials that have shape memory

Posted: 24 Sep 2012 07:18 AM PDT

A team of researchers in Spain has developed a device that works as a windshield wiper to eliminate Mars dust from the sensors on the NASA spacecrafts that travel to the Red Planet.
