Uptake protein acts as zinc’s doorway to the cell

UPTON, NY -- 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, conducte...

New highly stable fuel-cell catalyst gets strength from its nano core

UPTON, NY - 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...

Engineered plants make potential precursor to raw material for plastics

UPTON, NY In theory, plants could be the ultimate green factories, engineered to pump out the kinds of raw materials we now obtain from petroleum-based chemicals. But in reality, getting plants to accumulate high levels of desired products has been...

Scientists produce transparent, light-harvesting material

LOS ALAMOS, New Mexico, NOVEMBER 3, 2010 -- Scientists at the U.S. Department of Energy's Los Alamos National Laboratory and Brookhaven National Laboratory have fabricated transparent thin films capable of absorbing light and generating electric cha...

Transparent conductive material could lead to power-generating windows

UPTON, NY - 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 larg...

PET scans reveal estrogen-producing hotspots in human brain

UPTON, NY - 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 estro...

Key difference in how TB bacteria degrade doomed proteins

UPTON, NY -- Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a key difference in the way human cells and Mycobacterium tuberculosis bacteria, which cause TB, deliver unw...

Ritalin improves brain function, task performance in cocaine abusers

UPTON, NY -- A brain-scanning study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, conducted with collaborators from Stony Brook University, reveals that an oral dose of methylphenidate, commonly known as Ritalin, improve...

Scientists reproduce matter as it first appeared after Big Bang

Recent results of a joint experiment conducted by 460 physicists from 57 research institutions in 12 countries strongly indicate that the scientists have succeeded in reproducing matter as it first appeared in the universe; this matter is called the quark-gluon plasma. The experiment, called PHENIX and conducted at the Brookhaven National Laboratory on Long Island, New York, has brought together physicists from Brazil, China, France, Germany, Hungary, India, Israel, Japan, South Korea, Russia, Sweden and the United States. The Israeli team is led by Prof. Itzhak Tserruya, head of the Weizmann Institute's Particle Physics Department. Tserruya and his colleagues have designed and built unique particle detectors that are a central part of PHENIX's detecting system.

Scientists Image Soft Tissues With New X-Ray Technique

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, in collaboration with researchers at Rush Medical College, have demonstrated the effectiveness of a novel x-ray imaging technology to visualize soft tissues of the human foot that are not visible with conventional x-rays. The technique, called Diffraction Enhanced Imaging (DEI), provides all of the information imparted by conventional x-rays as well as detailed information on soft tissues previously accessible only with additional scanning methods such as ultrasound or magnetic resonance imaging (MRI). This study appears in the May 2003 issue of the Journal of Anatomy.
