That '4 hour erection': new discovery may help prevent a complication of priapism
For men coping with painful erections lasting for long periods of time, or priapism, new research published online in The FASEB Journal (http://www.fasebj.org) offers hope. view more (2009-10-27)
Genetic pathway critical to disease, aging found
The same chemical reaction that causes iron to rust plays a similarly corrosive role in our bodies. Oxidative stress chips away at healthy cells and is a process, scientists know, that contributes to a host of diseases and conditions in humans ranging from Alzheimer's, heart disease and stroke to cancer and the inexorable process of aging. view more (2008-02-21)
New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)
Study broadens understanding of enzymes linked to tumor promoting molecule
Virginia Commonwealth University Massey Cancer Center researchers have found that two enzymes that catalyze the same reaction and produce the same product have opposite effects on cell growth and death. view more (2005-11-07)
Laser Therapy Offers Alternative to Surgery for Liver Tumours
Research News in the British Journal of Surgery 11 September 2003: Laser light can be delivered in a controlled and predictable manner to destroy tumours. By inserting fibre optic cables through needles, doctors can direct the powerful laser light onto liver tumours - killing the cells and thus eliminating the need for major surgery. A review of... view more... (2003-09-11)
Building a Better Protein
Proteins are widely viewed as a promising alternative to synthetic chemicals in everything from medications to hand lotion. The naturally occurring molecules have been shown to be more efficient and effective than many of the most sophisticated chemical compounds on the market. view more (2009-02-24)
Bigger is better when it comes to the G spot
DRUGS such as Viagra should work for some women- especially if they have a big G spot. This spot, famed for producing spectacular orgasms, turns out to be awash with the enzymes that these drugs act on. The term G spot, coined by Ernest Grafenberg in 1950, refers to an area a few centimetres up inside the vagina on the side closest to a woman`s... view more... (2002-07-03)
Naturally occurring enzyme can break down key part of Alzheimer's plaques
Scientists have identified a naturally occurring enzyme that can break down a key component of the brain plaques characteristic of Alzheimer's disease. view more (2006-10-25)
Extreme environment biology research may help solve lignocellulosic ethanol puzzle
Buried beneath a sulfurous cauldron in European seas lies a class of microorganisms known as "extremophiles," so named because of the extreme environmental conditions in which they live and thrive. view more (2007-06-13)
Yale study offers insight into possible cause of lymphoma
The immune system's powerful cellular mutation and repair processes appear to offer important clues as to how lymphatic cancer develops, Yale School of Medicine researchers report this week in Nature. view more (2008-02-15)
Iowa State researchers use fungus to improve corn-to-ethanol process
Growing a fungus in some of the leftovers from ethanol production can save energy, recycle more water and improve the livestock feed that's a co-product of fuel production. view more (2008-05-28)
Caltech engineers build mini drug-producing biofactories in yeast
Researchers at the California Institute of Technology have developed a novel way to churn out large quantities of drugs, including antiplaque toothpaste additives, antibiotics, nicotine, and even morphine, using mini biofactories--in yeast. view more (2008-08-18)
UC research discovers new way to fight antibiotic-resistant bacteria
Research by a team at the University of Cincinnati (UC) has helped in the discovery of a new way to fight antibiotic-resistant bacteria, responsible for preventing treatment of lung infections in patients with cystic fibrosis and life-threatening cases of pneumonia. view more (2007-03-19)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis. view more (2007-04-02)
Long-term L-carnitine supplementation prevents development of liver cancer
A study will be published on March 21, 2009 in World Journal of Gastroenterology addresses the question. A research group in King Saud University, Kingdom of Saudi Arabia investigated, for the first time, the role of carnitine, a naturally occurring compound that is synthesized mainly in the liver, during the development of hepatocarcinogenesis. view more (2009-03-24)
Future therapies for stroke may block cell death
A new therapy to re-activate silenced genes in patients who suffer from neurodegenerative diseases or stroke is being developed by researchers at the University of Illinois at Chicago and Cornell University. view more (2007-06-14)
Researchers Genetically Engineer Microorganisms into Tiny Factories
Microorganisms may soon be efficiently and inexpensively producing novel pharmaceutical compounds, such as flavonoids, that fight aging, cancer or obesity, as well as high-value chemicals. view more (2007-09-19)
Green catalysts provide promise for cleaning toxins and pollutants
Tetra-Amido Macrocyclic Ligands (TAMLs) are environmentally friendly catalysts with a host of applications for reducing and cleaning up pollutants, and a prime example of "green chemistry." Carnegie Mellon University's Terry Collins, the catalyst's inventor, believes that the small-molecule catalysts have the potential to be even more... view more... (2008-08-18)
