Elucidation of the genome for diabetics with DNA chips
The genome of patients with type 2 diabetes (DT2) has been elucidated, for the first time, thanks to the use of new DNA chip technologies allowing 400,000 DNA mutations to be studied simultaneously. view more (2007-02-14)
Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects. view more (2008-06-17)
Turning Sunlight into Liquid Fuels: Berkeley Lab Researchers Create a Nano-sized Photocatalyst for Artificial Photosynthesis
For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water. view more (2009-03-11)
UCLA, University of Michigan Chemists Report Progress in Quest to Use Hydrogen as Fuel for Cars and Electronic Devices
Chemists at UCLA and the University of Michigan report an advance toward the goal of cars that run on hydrogen rather than gasoline. view more (2006-03-08)
Sunlight exposure plus low antioxidant levels may place older adults at risk for eye disease
A European study suggests that the combination of low plasma levels of antioxidants and blue light exposure from the sun is associated with certain forms of the eye disease age-related macular degeneration (AMD), according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-10-14)
In Nature, Proteins Sweep up Nanoparticles
Here's a pollution-control tip from nature: Deep inside a flooded mine in Wisconsin, scientists from several institutions including the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a world in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. view more (2007-06-18)
Nanotube formation: researchers learn to control the dimensions of metal oxide nanotubes
Moving beyond carbon nanotubes, researchers are developing insights into a remarkable class of tubular nanomaterials that can be produced in water with a high degree of control over their diameter and length. view more (2007-08-24)
New study: pine bark extract boosts nitric oxide production
A study to be published in the October edition of Hypertension Research reveals Pycnogenol, (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree, helps individuals by enhancing healthy nitric oxide (NO) production which leads to an increase in blood flow and oxygen supply to muscles. view more (2007-10-18)
New contrast agents may be on horizon for better medical imaging
Research by scientists based at the University of Illinois at Urbana-Champaign may lead to the development of a new breed of "multimodal" contrast agents that could work within a host of medical imaging platforms — from ultrasound and computed tomography (CT) to magnetic resonance imaging and molecular imaging. view more (2006-06-08)
Lack of sleep activates body's defence mechanisms
A lack of sleep is considered a threat situation, which activates the body's defence mechanisms. This is the same type of response that protects the body against viruses and bacteria as well as in stress situations. view more (2005-03-16)
Scientists develop life-saving chrome
British scientists have developed a safer and more versatile alternative to chrome electroplating, the coating found on vintage car bumpers, steel camshafts, and fixtures such as door furniture and light fittings. view more (2005-09-21)
Enzyme involved in inflammatory bowel disease discovered at Penn State College of Medicine
Researchers at Penn State College of Medicine, working with biochemists, geneticists and clinicians at the University of Bern, Switzerland and in the United Kingdom, have discovered an enzyme that has a key role in inflammatory bowel disease (IBD). view more (2009-06-03)
Flavanols key to potential chocolate benefits
Phytochemicals known as flavanols, which are found in chocolate, fruits and vegetables, can boost the levels of nitric oxide in the blood of smokers and reverse some of their smoking-related impairment in blood vessel function. view more (2005-09-29)
Antioxidants do not prevent degenerative eye disease
A diet rich in antioxidant vitamins and minerals does not seem to prevent the degenerative eye disease known as age related macular degeneration, finds a study published on bmj.com today. view more (2007-10-09)
Ionophore reverses Alzheimer's within days in mouse models
Scientists report a remarkable improvement in Alzheimer's transgenic mice following treatment with a new drug. The study, published by Cell Press in the July 10th issue of the journal Neuron, provides the first demonstration that an ionophore, a compound that transports metal ions across cell membranes, can elicit rapid and pronounced improvement... view more...

Pulmonary hypertension in children may result from reduced activity of gene regulator
Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say. view more (2009-03-06)
New Graphene-Based Material Clarifies Graphite Oxide Chemistry
A new "graphene-based" material that helps solve the structure of graphite oxide and could lead to other potential discoveries of the one-atom thick substance called graphene, which has applications in nanoelectronics, energy storage and production, and transportation such as airplanes and cars, has been created by researchers at The... view more...

Cause of gender differences in blood pressure, kidney damage under study
While men and women both get high blood pressure and related kidney disease, the path to get there is shorter, steeper and just different for men, researchers say. view more (2007-05-03)
Levels of folate in men's diets is linked to chromosomal abnormalities in their sperm
Researchers have found an association between a vitamin found in leafy green vegetables, fruit and pulses and levels of chromosomal abnormalities in men's sperm. Men who consumed high levels of folate (a water-soluble B vitamin that occurs naturally in food) and folic acid (the synthetic form of the vitamin) tended to have lower levels of abnormal... view more...

High-fat, copper-rich diets associated with increased rates of cognitive decline in older adults
Among older adults whose diets are high in saturated and trans fats, a high intake of copper may be associated with an accelerated rate of decline in thinking, learning and memory abilities. view more (2006-08-15)
