Atomic structure of the mammalian 'fatty acid factory' determined
Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders. view more (2008-09-05)
Antitumor agent under the microscope
Mechanical stabilization of DNA keeps tumor cells in check Cisplatin is one of the most widely employed cancer medications. As with many other chemotherapy agents, the mechanism by which it works has not been fully researched. Now, thanks to Munich physicists Hermann E. Gaub, Rupert Krautbauer, and Hauke Clausen-Schaumann, an important step toward... view more... (2000-10-30)
An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. view more (2009-11-20)
EARLIER DETECTION FOR BREAST CANCER IN SIGHT
One in twelve women in the UK will experience breast cancer during their life, one of the highest incidences in the world. Scientists at Cranfield University's Shrivenham Campus have been looking at ways in which new developments in materials science can assist us in the fight against such cancers. view more (2000-03-15)
Decoding the dictionary: Study suggests lexicon evolved to fit in the brain
The latest edition of the Oxford English Dictionary boasts 22,000 pages of definitions. While that may seem far from succinct, new research suggests the reference manual is meticulously organized to be as concise as possible - a format that mirrors the way our brains make sense of and categorize the countless words in our vast vocabulary. view more (2008-05-01)
University of Pennsylvania engineers discover natural 'workbench' for nanoscale construction
Engineers at the University of Pennsylvania have taken a step toward simplifying the creation of nanostructures by identifying the first inorganic material to phase separate with near-perfect order at the nanometer scale. view more (2007-07-18)
Algorithm advance produces quantum calculation record
Two theoreticians from the National Institute of Standards and Technology (NIST) and Indiana University (IU) have published the most accurate values yet for fundamental atomic properties of a molecule-values calculated from theory alone. view more (2006-03-21)
Researchers figure out what makes a simple biological clock tick
An interdisciplinary team of researchers at Vanderbilt University has analyzed the simplest known biological clock and figured out what makes it tick. view more (2007-03-27)
Ytterbium's Broken Symmetry
Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame. view more (2009-07-23)
X-ray Science gets a further £3.4M
A world-leading UK research project to study the properties of new materials has been given further funding of £3.4M. The grant is for the continued operation of the British funded X-ray Beamline ( XMaS - X-ray Magnetic Scattering) based at the European Synchrotron Radiation Facility at Grenoble, France. In very basic terms the synchrotron... view more... (2002-05-28)

Argonne scientists use unique diamond anvils to view oxide glass structures under pressure
Researchers at the U.S. Department of Energy's Argonne National Laboratory have used a uniquely-constructed perforated diamond cell to investigate oxide glass structures at high pressures in unprecedented detail. view more (2007-11-09)
Researchers move closer to switching nuclear isomer decay on and off
Livermore researchers have moved one step closer to being able to turn on and off the decay of a nuclear isomer. view more (2007-04-06)
Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means... view more... (2009-01-22)
The hormone of darkness: melatonin could hurt memory formation at night
What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep? A University of Houston professor and his team of researchers may have some answers. view more (2007-11-16)
Quantum mechanics predicts unusual lattice dynamics of vanadium metal under high pressure
A Swedish research team of Dr. Wei Luo & Professor Rajeev Ahuja and US team of Dr. Y. Ding & Prof. H.K. Mao have used theoretical calculations to understand a totally new type of high-pressure structural phase transition in Vanadium. view more (2007-10-12)
New method for dating art prints and early books borrows know-how from genetic science
A new and relatively simple method for discovering the date when centuries-old art prints and books were produced has been developed at Penn State. view more (2006-06-21)
B2MIN9: Beagle 2 Teams Continue Efforts To Communicate With The Lander
Scientists are still waiting to hear from the Beagle 2 lander on Mars. Two attempts to communicate with Beagle 2 during the last 24 hours - first with the 250 ft (76 m) Lovell Telescope at Jodrell Bank Observatory in Cheshire, UK, and then this morning with the Mars Odyssey orbiter - ended without receiving a signal. Despite this outcome, two... view more... (2003-12-27)
New telomere discovery could help explain why cancer cells never stop dividing
A group working at the Swiss Institute for Experimental Cancer Research (ISREC) in collaboration with the University of Pavia has discovered that telomeres, the repeated DNA-protein complexes at the end of chromosomes that progressively shorten every time a cell divides, also contain RNA. view more (2007-10-05)
Emergency angioplasty patients do best at hospitals where it's the 'default' treatment
Across America, hospitals large and small have been racing to offer angioplasty and other minimally invasive treatments to open blocked heart arteries. view more (2006-01-17)
