Computer predicts reactions between molecules and surfaces, with 'chemical precision'
Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science. view more (2009-11-09)
Early detection of Alzheimer's disease a possibility
Research investigating concentrations of magnetite, a magnetic form of iron, in Alzheimer's disease tissue has produced preliminary results that suggest the possibility of developing a technique to detect Alzheimer's disease before clinical symptoms appear. The research*, published in Biology Letters, an online supplement to the Royal Society's... view more... (2003-04-07)
New light shed on the enigma of salt intake and hypertension
A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma. view more (2009-05-04)
Largest study of fertility patients shows concerns about embryo disposition
Fertility patients who are done having children feel responsible for the stored, frozen embryos left over from their treatment, yet more than half are against implanting the embryos in anyone else, according to a new study by researchers at Duke University Medical Center. view more (2008-12-04)
Peer-to-peer heart monitoring
The possibility of remote monitoring for chronically ill patients will soon become a reality. Now, researchers in South Africa and Australia have devised a decentralized system to avoid medical data overload. They describe the peer-to-peer system in a forthcoming issue of the International Journal of Computer Applications in Technology. view more (2009-03-09)
Just Scratching the Surface: New Technique Maps Nanomaterials as They Grow
Researchers at Rensselaer Polytechnic Institute have developed a measurement technique that will help scientists and companies map nanomaterials as they grow. view more (2008-11-05)
Montreal researchers probe the genetic basis of memory
A group of Montreal researchers has discovered that GCN2, a protein in cells that inhibits the conversion of new information into long-term memory, may be a master regulator of the switch from short-term to long-term memory. view more (2005-08-31)
A better way to pinpoint underground oil reserves
Picture this: an accurate map of a large underground oil reservoir that can guide engineers' efforts to coax the oil from the vast rocky subsurface into wells where it can be pumped out for storage or transport. view more (2009-01-29)
New Hybrid Nanostructures Detect Nanoscale Magnetism
A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials exhibit interesting and potentially beneficial new properties. view more (2008-12-09)
Invention could solve "bottleneck" in developing pollution-free cars
Hydrogen-powered cars that do not pollute the environment are a step closer thanks to a new discovery which promises to solve the main problem holding back the technology. view more (2006-12-05)
Researchers improve ability to write and store information on electronic devices
ew research led by the U.S. Department of Energy's Argonne National Laboratory physicist Matthias Bode provides a more thorough understanding of new mechanisms, which makes it possible to switch a magnetic nanoparticle without any magnetic field and may enable computers to more accurately write and store information. view more (2007-09-14)
Baby born from sperm frozen for record 21 years
UK researchers writing in Europe's leading reproductive medicine journal Human Reproduction[1], today (Tuesday 25 May) report what they believe to be a world record - a baby born using sperm that had been frozen for 21 years. "We believe this is the longest period of sperm cryopreservation resulting in a live birth so far reported in the... view more... (2004-05-23)
Seeing the forest and the trees
With human emissions of carbon dioxide on the rise, there is growing interest in maintaining the Earth's natural mechanisms that absorb and store carbon. view more (2005-10-24)
The Not-So-Digital Future of Digital Signal Processing
Fungi processing audio signals. E. Coli storing images. DNA acting as logic circuits. It's possible, and in some cases, it's already happened. In any event, performing digital signal processing using organic and chemical materials without electrical currents could be the wave of the future. view more (2008-04-08)
Pitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from... view more...

Wax-based heat storage for buildings
Everybody visiting an old church or temple has experienced the cooling effect of thick walls. On the other hand, heat waves particularly affect buildings constructed in lightweight materials. The walls cannot absorb much thermal energy, causing room temperatures to increase rapidly in summer. Researchers at the Fraunhofer Institute for Solar... view more... (2003-07-25)
New technique for cancer screening
Current research suggests that a new technique to determine tumor methylation status can be used in archived tissue samples. view more (2009-02-24)
Uterus sparing surgery is a safe and effective treatment for pelvic organ prolapse
Researchers presented data at the 104th Annual Scientific Meeting of the American Urological Association (AUA) showing that uterus sparing surgery is an effective and safe treatment for women who want to preserve the integrity of vaginal function after pelvic organ prolapse. view more (2009-04-27)
Planting carbon deep in the earth -- rather than the greenhouse
Storing carbon dioxide deep below the earth's surface could be a safe, long-term solution to one of the planet's major contributors to climate change. view more (2007-11-27)
More safety for cell phone batteries
Fraunhofer researchers will be presenting a novel lithium-ion battery at Hannover Messe on April 21 - 25. It is based on a polymer electrolyte, which is - unlike the liquid electrolyte in conventional lithium-ion batteries - not inflammable. A test set-up for redox flow batteries will also be on display at the show. view more (2008-04-14)
