A low-power, magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas–a million times weaker than the Earth’s magnetic field–has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the Dec. 27 issue of Applied Physics Letters,* the device can be powered with batteries and is about 100 times smaller than current atom-based sensors with similar sensitivities, which typically wei

May help decipher regulator proteins’ roles in cell differentiation, cancer, and more

Finding out where gene-regulator proteins bind to DNA and identifying the genes they regulate just got a step easier thanks to a new technique developed by scientists at the U.S. Department of Energy’s Brookhaven National Laboratory. The technique could greatly speed the process of unraveling the role these proteins play in turning on and off the genes that establish the very identity of cells —

The biggest research project ever sponsored by the EU in the seafood sector will help to meet the consumer demand for more healthy products.

With the support of 14.4 million euros of EU funding under the ’food quality and safety’ priority of the current Framework Funding programme (FP6), SEAFOODplus aims to satisfy the growing consumer demands for healthy, safe products that are produced using sustainable, environmentally friendly methods and processed using state of the

Experiments led by Nicolas Dauphas of the University of Chicago and Chicago’s Field Museum have validated some controversial rocks from Greenland as the potential site for the earliest evidence of life on Earth.

“The samples that I have studied are extremely controversial,” said Dauphas, an Assistant Professor in Geophysical Sciences at the University of Chicago and a Field Museum Associate. Some scientists have claimed that these rocks from Greenland’s banded iron for

All stories have one beginning, one middle and one end. But with MECiTV’s interactive television (iTV) authoring platform, producers can easily create programmes in which viewers choose how the story unravels and ends.

As Carmen Mac Williams, MECiTV Project Manager at Cologne’s Institute at the Academy of Media Arts explains, MECiTV arose out of “discontent with traditional linear recording of political events or anything happening in the world, where only one viewpoint is pres

Could be target for cancer therapeutics

MA-Researchers have discovered an enzyme that plays an important role in controlling which genes will be turned on or off at any given time in a cell. The novel protein helps orchestrate the patterns of gene activity that determine normal cell function. Their disruption can lead to cancer.

The elusive enzyme, whose presence in cells was suspected but not proven for decades, came to light in the laboratory of Yang Shi, HMS professor o
