Figurines of Aphrodite from the era of the Roman Empire discovered in Hippos
The hidden figurines were discovered when the researchers exposed a shop in the southeastern corner of the forum district of Sussita, which is the central area of the Roman city that was built in the second century B.C., existed through the Roman and Byzantine periods and destroyed in the great earthquake of 749 A.D.

Electronic nose sniffs out toxins
Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors.

Researchers using parallel processing computing could save thousands by using an Xbox
A new study by a University of Warwick researcher has demonstrated that researchers trying to model a range of processes could use the power and capabilities of a particular XBox chip as a much cheaper alternative to other forms of parallel processing hardware.

Opto-electronic nose sniffs out toxic gases
Imagine a polka-dotted postage stamp that can sniff out poisonous gases or deadly toxins simply by changing colors.

UCSF researchers program cells to be remote-controlled by light
UCSF researchers have genetically encoded mouse cells to respond to light, creating cells that can be trained to follow a light beam or stop on command like microscopic robots.

Are the monoamines involved in shaping conduct disorders?
Apart from psychosocial influences, biological factors have a major influence on personality traits and behavior.

New drug lowers high blood pressure in patients resistant to conventional medication
A new drug -- darusentan -- provides additional reduction in blood pressure in patients who have not attained their treatment goals with three or more anti-hypertensive drugs.

Evolution still scientifically stable
An international team of researchers, including Monash University biochemists, has discovered evidence at the molecular level in support of one of the key tenets of Darwin's theory of evolution.

Looking deeply into polymer solar cells
Researchers from the Eindhoven University of Technology and the University of Ulm have made the first high-resolution 3-D images of the inside of a polymer solar cell.

Master gene that switches on disease-fighting cells identified by scientists

When nano may not be nano
A new analysis by an international team of researchers from the Center for the Environmental Implications of NanoTechnology, based at Duke University, argues for a new look at the way nanoparticles are selected when studying the potential impacts on human health and the environment.

New CO2 data helps unlock the secrets of Antarctic formation
The link between declining CO2 levels in the Earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

High-res view of zinc transport protein
New, improved-resolution views of a zinc transporter protein deciphered at Brookhaven National Laboratory suggest a mechanism for how cells sense and regulate zinc, an element that is essential for life.

Water quality in orbit
Space is not a fun place to get a stomach bug.

How stem cells make skin
Scientists at the European Molecular Biology Laboratory in Monterotondo, in collaboration the Centro de Investigaciones Energ├ęticas, Medioambientales y Tecnologicas in Madrid, have discovered two proteins that control when and how stem cells switch to being skin cells.
