A new hope for heavy metal contaminated soils
In the 1980s scientists began laboratory studies on metal hyperaccumulator plants, i.e. plants which accumulate exceptionally high concentrations of heavy metals in their above-ground biomass. This coincided with the recognition that a number of serious human diseases are the result of disruptions in metal homeostasis, for example Menke's disease,... view more... (2003-12-05)
Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. view more (2006-04-03)
Cholera pathogen reveals how bacteria generate energy to live
Researchers at Rensselaer Polytechnic Institute have discovered new details about how bacteria generate energy to live. In two recently published papers, the scientists add key specifics to the molecular mechanism behind the pathogen that causes cholera. view more (2007-01-30)
Methane bacteria possess pressure valve
Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems to be of vital importance for the microorganism.... view more...

Membrane fusion at the synapse: Janus faced synaptotagmin-1 helps to keep the fast pace
Imagine a bathtub with two soap bubbles colliding but never fusing. Then you add detergent, and the surface of the water goes flat as the walls of the bubbles collapse and merge. view more (2008-10-30)
NIST demonstrates 'universal' programmable quantum processor
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics-the rules governing the submicroscopic world-using two quantum bits (qubits) of information. view more (2009-11-16)
Organic Soils Continue to Acidify Despite Reduction in Acidic Deposition
Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. view more (2009-01-13)
HERA GETS GOING WITH ELECTRONS
The Hadron Electron Ring Accelerator (HERA) at the DESY laboratory in Hamburg is about to begin operations for 1998 with a return to electrons. Since 1993, the machine has been producing head-on collisions between high-energy protons and positrons - the antimatter equivalent of electrons. Now it is ready to get going with electrons again. view more (1998-08-11)
Researchers create first nanofluidic transistor, the basis of future chemical processors
University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first "nanofluidic" transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels. view more (2005-06-30)
Detecting anthrax proteins at ultralow concentrations
A new laboratory method for quickly detecting active anthrax proteins within an infected blood sample at extremely low levels has been developed. view more (2005-08-29)
Motorola researchers develop selective sensors based on carbon nanotubes
A team of researchers from Arizona State University and Motorola Labs, the applied research arm of Motorola Inc., has developed sensors based on carbon nanotubes, microscopically small structures that posses excellent electronic properties. view more (2006-09-14)
UCI scientists use nanotechnology to create world's fastest method for transmitting information in cell phones and computers
UC Irvine scientists in The Henry Samueli School of Engineering have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz. view more (2005-06-10)
Scientists discover how coffee can reduce risk of pancreatitis
Scientists at the University of Liverpool have found how coffee can reduce the risk of alcohol-induced pancreatitis. view more (2006-03-14)
Synthetic cells shed biological insights while delivering battery power
Trying to understand the complex workings of a biological cell by teasing out the function of every molecule within it is a daunting task. view more (2009-10-23)
NIST studies how new helium ion microscope measures up
Just as test pilots push planes to explore their limits, researchers at the National Institute of Standards and Technology (NIST) are probing the newest microscope technology to further improve measurement accuracy at the nanoscale. view more (2008-09-05)
The Nobel Prize in Chemistry 2003
The two American scientists Peter Agre, 54, and Roderick MacKinnon, 47, will receive this years Nobel Prize in Chemistry "for discoveries concerning channels in cell membranes". view more (2003-10-09)
New biochip helps study living cells, may speed drug development
Purdue University researchers have developed a biochip that measures the electrical activities of cells and is capable of obtaining 60 times more data in just one reading than is possible with current technology. view more (2006-10-23)
'CARS' imaging reveals clues to myelin damage
Researchers have discovered that calcium ions could play a crucial role in multiple sclerosis by activating enzymes that degrade the fatty sheath that insulates nerve fibers. view more (2007-06-28)
Researchers identify proteins making up mechanosensitive ion channels
Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery. view more (2008-06-03)
Drug slows and may halt Parkinson's disease
Northwestern University researchers have discovered a drug that slows - and may even halt - the progression of Parkinson's disease. view more (2007-06-11)
