24.12.2008 | Press monitoring
Infectious pathogens like Salmonella typhimurium employ a startling array of techniques to skillfully outwit the body's defense mechanisms and produce illness. Through their expression of genes—the fundamental building blocks of cellular physiology—such microbes ingeniously adapt to varied environments, modifying their disease-causing potential or...
Stanford fruit-fly study adds weight to the theories about another type of adult stem cell
23.12.2008 | Press monitoring
It turns out that an old dog—or at least an old fruit-fly cell—can learn new tricks. Researchers at the Stanford University School of Medicine have found that mature, specialized cells naturally regress to serve as a kind of de facto stem cell during the fruit-fly life cycle. The surprising discovery counters the common belief that the ability...
Advance In The Battle Against 'Gray Mold'
22.12.2008 | Press monitoring
Scientists are reporting identification of the cluster of genes responsible for the toxins produced by "gray mold," a devastating plant disease that kills almost 200 different food and ornamental plants including tomatoes, strawberries and roses.
Transgenic increases in seed oil content are associated with the differential expression of novel Brassica-specific transcripts
21.12.2008 | Press monitoring
Seed oil accumulates primarily as triacylglycerol (TAG). While the biochemical pathway for TAG biosynthesis is known, its regulation remains unclear. Previous research identified microsomal diacylglycerol acyltransferase 1 (DGAT1, EC 2.3.1.20) as controlling a rate-limiting step in the TAG biosynthesis pathway. Of note, overexpression of DGAT1...
Engineering Algae to Make Fuel Instead of Sugar

In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green.
Single virus used to convert adult cells to embryonic stem cell-like cells
19.12.2008 | Press monitoring
Whitehead Institute researchers have greatly simplified the creation of so-called induced pluripotent stem (iPS) cells, cutting the number of viruses used in the reprogramming process from four to one. Scientists hope that these embryonic stem-cell-like cells could eventually be used to treat such ailments as Parkinson’s disease and...
Why A Virus With Unusual Properties Injects Unusual Substance Into E. Coli Bacteria
18.12.2008 | Press monitoring
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell.
Gene therapy corrects sickle cell disease in laboratory study
17.12.2008 | Press monitoring
Using a harmless virus to insert a corrective gene into mouse blood cells, scientists at St. Jude Children's Research Hospital have alleviated sickle cell disease pathology. In their studies, the researchers found that the treated mice showed essentially no difference from normal mice.
New Class Of Anti-inflammatory Drugs Developed
16.12.2008 | Press monitoring
In the treatment of pain, inflammation and fever, non-steroid anti-rheumatic drugs (NSAR) such as acetylsalicylic acid - more commonly known as Aspirin - or Ibuprofen have always been popular choices. However, had they been tested using today's stringent criteria, many of these drugs would not have passed the clinical trial stage, due to the...
