Speaking directly into a cellphone while holding it against your ear can alter brain activity in those areas closest to the device's antenna, claims a new study published Tuesday in the Journal of the American Medical Association (JAMA). Researchers at the National Institutes of Health (NIH) and the Brookhaven National Laboratory in New York studied 47 adults over the course of a year, using positron emission tomography (PET) to measure their glucose metabolism, or the amount of sugar it...

Direct measurements allow detailed look at how quarks of different flavors contribute to spin Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal "” the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton. The technique,...

Newly discovered phase helps explain materials' ability to convert waste heat to electricity Scientists have discovered that a class of materials known to convert heat to electricity and vice versa behaves quite unexpectedly at the nanoscale in response to changes in temperature. The discovery - described in the December 17, 2010, issue of Science - is a new "opposite-direction" phase transition that helps explain the strong thermoelectric response of these materials. It may also help...

Understanding how lignin building blocks are transported could break down barriers to biofuel production One big challenge in converting plants to biofuels is that the very same molecules that keep plants standing up make it hard to break them down. Now scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are unraveling details of how plant cells' structural supports - their cell walls - are made, with the hope of finding ways to change their composition for more...

UBC and TRIUMF physicists have proposed a unified explanation for dark matter and the so-called baryon asymmetry--the apparent imbalance of matter with positive baryon charge and antimatter with negative baryon charge in the Universe. The visible Universe appears to be made of atoms, and each of these atoms carries a positive baryon charge equal to total number of protons and neutrons in its nucleus. However, since the discovery of antimatter in 1932, researchers have wondered why the...

By Daisy Yuhas, Brookhaven National Laboratory Discovery of mechanism sheds light on how zinc "” essential to the growth of all living organisms "” enters cells A study to be published as the "Paper of the Week" in the Journal of Biological Chemistry this December details how zinc, an element fundamental to cell growth, enters the cell via zinc-specific uptake proteins. The research, conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, is the first to...

Palladium core protects precious platinum; enhances reactivity/stability Stop-and-go driving can wear on your nerves, but it really does a number on the precious platinum that drives reactions in automotive fuel cells. Before large fleets of fuel-cell-powered vehicles can hit the road, scientists will have to find a way to protect the platinum, the most expensive component of fuel-cell technology, and to reduce the amount needed to make catalytically active electrodes. Now, scientists at the...

Combines elements for light harvesting and electric charge transport over large, transparent areas Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Los Alamos National Laboratory have fabricated transparent thin films capable of absorbing light and generating electric charge over a relatively large area. The material, described in the journal Chemistry of Materials, could be used to develop transparent solar panels or even windows that absorb solar energy...

New radiotracer application reveals features unique to humans; may advance understanding of estrogen-related diseases A study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has demonstrated that a molecule "tagged" with a radioactive form of carbon can be used to image aromatase, an enzyme responsible for the production of estrogen, in the human brain. The research, published in the November issue of Synapse, also uncovered that the regions of the brain where...
