UCLA researchers create 'fly paper' to capture circulating cancer cells
Just as fly paper captures insects, an innovative new device with nano-sized features developed by researchers at UCLA is able to grab cancer cells in the blood that have broken off from a tumor. view more (2009-11-19)
Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine. view more (2009-11-12)
Size matters: Obesity leading risk factor of left atrial enlargement during aging
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death. view more (2009-11-10)
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)
Findings show nanomedicine promising for treating spinal cord injuries
Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident. view more (2009-11-09)
Study shows how carbon nanotubes can affect lining of the lungs
Carbon nanotubes are being considered for use in everything from sports equipment to medical applications, but a great deal remains unknown about whether these materials cause respiratory or other health problems. view more (2009-10-26)
Researchers discover RNA repair system in bacteria
In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria. view more (2009-10-13)
New aluminum-water rocket propellant promising for future space missions
Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies. view more (2009-10-08)
Models begin to unravel how single DNA strands combine
Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix. view more (2009-10-07)
Licence to go where no chemist has gone before
Scientists at The University of Nottingham have overcome one of the significant research challenges facing electrochemists. For the first time they have found a way of probing right into the heart of an electrochemical reaction. view more (2009-09-29)
Shedding light on cancer cells
Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. view more (2009-09-25)
Concentrating emissions
Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants. view more (2009-09-22)
Smaller isn't always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality. view more (2009-09-18)
URI researcher trips amputees in effort to develop improved prosthetic legs
Again and again, 71-year-old Marjorie Brasier walked on the treadmill using an instrumented prosthetic leg, and again and again she tripped or slipped. Sometimes she recovered on her own and kept walking, while at other times the harness she wore was all that kept her from tumbling to the floor. view more (2009-09-16)
New X-ray technique illuminates reactivity of environmental contaminants
A chemical reaction can occur in the blink of an eye. view more (2009-09-16)
Trust your gut? Study explores religion, morality and trust in authority
In a world filled with dogma, doctrine and discipline, it is accurate to say most of us strive to do what we believe is "right." These convictions and beliefs permeate every aspect of our lives, including education, ethics and even common law. view more (2009-09-15)
Conflict between plant and animal hormones in the insect gut?
Cis-OPDA (12-oxophytodienoic acid) is a highly reactive plant hormone which simultaneously serves as a precursor molecule of the metabolic "master switch" jasmonic acid. view more (2009-09-15)
Research Matters at the Arizona Health Sciences Center (AHSC): UA Researchers Seek Safer Cystic Fibrosis Test
Researchers from The University of Arizona Colleges of Pharmacy and Medicine are teaming up to try to invent a novel non-invasive lung test for cystic fibrosis sufferers. view more (2009-09-10)
Piece from childhood virus may save soldiers' lives
A harmless shard from the shell of a common childhood virus may halt a biological process that kills a significant percentage of battlefield casualties, heart attack victims and oxygen-deprived newborns. view more (2009-09-08)
Powerful new 'molecular GPS' helps probe aging and disease processes
Scientists in Michigan are reporting the development of a powerful new probe for identifying proteins affected by a key chemical process important in aging and disease. view more (2009-09-02)
