Researchers begin to decipher metabolism of sexual assault drug
It's a naturally occurring brain chemical with an unwieldy name: 4-hydroxybutyrate (4-HB). Taken by mouth, it can be abused or used as a date-rape drug. view more (2009-11-20)
New explanation for nature's hardiest life form
Got food poisoning? The cause might be bacterial spores, en extremely hardy survival form of bacteria, a nightmare for health care and the food industry and an enigma for scientists. view more (2009-11-13)
No-entry zones for AIDS virus
The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs. view more (2009-11-13)
UCLA researchers reconstitute enzyme that synthesizes cholesterol drug lovastatin
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have for the first time successfully reconstituted in the laboratory the enzyme responsible for producing the blockbuster cholesterol-lowering drug lovastatin. view more (2009-11-04)
UC Riverside Researchers Create First Synthetic Cellulosome in Yeast
A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found. view more (2009-10-30)
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)
GSU professor develops new method to help keep fruit, vegetables and flowers fresh
Did you know that millions of tons of fruits and vegetables in the United States end up in the trash can before being eaten, according to the U.S. Department of Agriculture? view more (2009-10-21)
Popping the cork on biofuel agriculture
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a novel enzyme responsible for the formation of suberin - the woody, waxy, cell-wall substance found in cork. view more (2009-10-20)
University of the Basque Country study on proteins related to Alzheimer
The cause, or at least one of the possible causes, of memory loss amongst Alzheimer sufferers is related to the location of certain proteins. view more (2009-10-16)
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)
Tech researchers using nanotechnology in biofuel process to save money, environment
Dr. James Palmer, associate professor of chemical engineering at Louisiana Tech University, is collaborating with fellow professors Dr. Yuri Lvov, Dr. Dale Snow, and Dr. Hisham Hegab to capitalize on the environmental and financial benefits of "biofuels" by using nanotechnology to further improve the cellulosic ethanol processes. view more (2009-10-09)
Iowa State University researcher uncovers potential key to curing tuberculosis
Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. Researchers have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis. view more (2009-10-02)
Mechanism for potential Friedreich's ataxia drug uncovered
Using clever chemistry, a Scripps Research team has pinpointed the enzyme target of a drug group that stops the progression of the devastating disease Friedreich's ataxia in mice and may do the same for humans. view more (2009-09-28)
University of Iowa scientists use blood-brain barrier as therapy delivery system
The blood brain barrier is generally considered an obstacle to delivering therapies from the bloodstream to the brain. However, University of Iowa researchers have discovered a way to turn the blood vessels surrounding brain cells into a production and delivery system for getting therapeutic molecules directly into brain cells. view more (2009-09-22)
New marker for Alzheimer's discovered
Gothenburg researchers have discovered a previously unknown substance in spinal fluid that can be used to diagnose Alzheimer's disease. 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)
Enzyme inhibitor takes an unexpected approach toward blocking cancer-promoting protein
Scientists at Fox Chase Cancer Center have discovered a unique method of attack that may be used to inhibit signaling enzymes called kinases, which often have a role in sustaining drug-resistant cancerous cells. They have confirmed that IPA-3, a small molecular inhibitor of a kinase called PAK1, targets the enzyme's regulatory domain, mimicking... view more... (2009-09-08)
Boron-based compounds trick a biomedical protein
Chemists and biologists have successfully demonstrated that specially synthesized boron compounds are readily accepted in biologically active enzymes, a move that, they say, is a proof of concept that could lead to new drug design strategies. view more (2009-09-03)
Newly found DNA catalysts cleave DNA with water molecule
Better tools for manipulating DNA in the laboratory may soon be possible with newly discovered deoxyribozymes (catalytic DNA) capable of cleaving single-stranded DNA, researchers at the University of Illinois say. view more (2009-08-17)
Scripps Research scientists find early evolution maximized the 'spellchecking' of protein sequences
As letters of the alphabet spell out words, when amino acids are linked to one another in a particular order they "spell out" proteins. view more (2009-08-07)
