Scientists at the University of California, San Diego have developed a new method for making scaffolds for culturing tissue in three-dimensional arrangements that mimic those in the body. This advance, published online in the journal Advanced Materials, allows the production of tissue culture scaffolds containing multiple structurally and chemically distinct layers using common laboratory r

A study published in the International Journal of Electronic Security and Digital Forensics this month suggests that parents and carers could be putting children at risk if they upload digital photos that are automatically "geotagged" by their camera.

Scientists at The Scripps Research Institute in California and the Technion–Israel Institute of Technology have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips. Although DNA has been used for encryption in the past, this is the first experimental demonstration of a molecular cryptosystem of images based

An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology.

In a paper published this week in Science, a Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon.

To improve the next generation of insect-size flying machines, Johns Hopkins engineers have been aiming high-speed video cameras at some of the prettiest bugs on the planet. By figuring out how butterflies flutter among flowers with amazing grace and agility, the researchers hope to help small airborne robots mimic these maneuvers.

A team of German researchers, with the help of a lecturer at the University of Alcalá (UAH, Spain), has developed a system that locates pedestrians in front of the vehicle using artificial vision. Soon to be integrated into the top-of-the-range Mercedes vehicles, the device includes two cameras and a unit that process information supplied in real time by all image points.

The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body.

Researchers at the Niels Bohr Institute have combined two worlds – quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new coo

University of Notre Dame nuclear physicists Philippe Collon and Michael Wiescher are using accelerated ion beams to pinpoint the age and origin of material used in pottery, painting, metalwork and other art. The results of their tests can serve as powerful forensic tools to reveal counterfeit art work, without the destruction of any sample as required in some chemical analysis.
