Researchers at the University of Warwick have found how a citric acid-based Achilles heel used by a pathogen that attacks the popular African Violet house plant could be exploited not just to save African Violets but also to provide a potentially effective treatment for Anthrax. The researchers examined how a chemical structure is assembled in a bacterial pathogen called Pectobacterium chrysanthemi (Dickya dadantii) that afflicts plants "“ particularly the African Violet which often...

A team of European researchers says hair grays with age as follicles become bleached first gray, and then white, from within. The researchers closely examined cell cultures of human hair follicles and found in the absence of the enzyme catalase, the hydrogen peroxide naturally produced in hair cells stops being broken down into water and oxygen. Also, hair follicles could not repair the damage caused by the accumulating hydrogen peroxide because of low levels of enzymes MSR A and B. High...

 A Duke University-led team has brought powerful software to the never-ending arms race between antibiotics and germs. Working together, computer scientists and biochemists have developed and laboratory-tested a computer program that can show experimentalists how to change the machinery that bacteria use to make natural antibiotics.The program -- a set of computer rules known as the algorithm "K*" (pronounced K Star)-- is able to sort through all the possible shapes and changes of a key...

Now, a pair of Scripps Research Institute scientists has taken a significant step toward answering that question. The scientists have synthesized for the first time RNA enzymes that can replicate themselves without the help of any proteins or other cellular components, and the process proceeds indefinitely.The work was published on Thursday, January 8, 2008, in Science Express, the advanced, online edition of the journal Science.In the modern world, DNA carries the genetic sequence for...

Enzyme, biological reaction essential to life takes 2.3 billion years All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these reactions proceed spontaneously, in the absence of enzymes "“ minutes, hours, days? And why even pose the question? One scientist who studies these issues is Richard Wolfenden, Ph.D., Alumni Distinguished Professor Biochemistry and Biophysics...

By The Associated Press DES MOINES (AP) - Critics are complaining that state environmental officials have done little about an outbreak of toxic algae that threatened the safety of drinking water in Iowa's largest city and posed a risk to swimmers at a west-central Iowa lake.They said the blue-green algae, or cyanobacteria, was found at Black Hawk Lake near Lake View, and that levels recorded just after Labor Day were seven times more than an internationally recognized benchmark for safe...

A U.S. scientist says a combination of the new drug trabectedin with pegylated liposomal doxorubicin provides clinical benefit for relapsed ovarian cancer. University of California-Irvine Associate Professor Bradley Monk said the combination, which does not include a platinum drug, challenges the current standard of treatment for women whose cancer recurs at least 6 months after first-line treatment. "This trial, which included almost two-thirds such women, challenges this traditional...

Scientists at Stanford University Medical Center reported Thursday that an enzyme that helps the body metabolize alcohol might also limit injury during a heart attack.  They also found that an experimental drug might amplify this protective effect, the researchers said. The scientists hope their study, performed in rats, may one day lead to a drug that would protect those suffering from the chest pain that often precedes a heart attack. Such a drug may also have uses during coronary...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
