Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis. view more (2008-08-19)
MicroRNA tweaks protein that controls early heart development
Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle. view more (2005-06-13)
Arginine discovery could help fight human obesity
A Texas AgriLife Research scientist and fellow researchers have discovered that arginine, an amino acid, reduces fat mass in diet-induced obese rats and could help fight human obesity. view more (2009-02-05)
How schizophrenia develops: Major clues discovered
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue. view more (2007-10-17)
Who found some new mechanisms of HBV virulence?
This dreadful HBV is small in size. The genome of this virus is a partial double stranded circle. When made fully double stranded, this genome carries about 3000 base pairs, compared to 200 kilo base pairs of the genome of the smallpox virus. view more (2008-02-25)
Ibuprofen or acetaminophen in long-term resistance training increases muscle mass/strength
Taking daily recommended dosages of ibuprofen and acetaminophen caused a substantially greater increase over placebo in the amount of quadriceps muscle mass and muscle strength gained during three months of regular weight lifting, in a study by physiologists at the Human Performance Laboratory, Ball State University. view more (2008-04-07)
Asthma risk increased in women with high levels of fat tissue inflammatory protein
Women with high levels of an inflammatory protein produced by fat tissue are at significantly increased risk of asthma, finds research in published ahead of print in Thorax. view more (2006-03-15)
Dictyostelium cells shown to lay 'breadcrumb trail' as first step in multicellular formation
When starved of their food source and then presented with a chemoattractant signal like cAMP, individual Dictyostelium cells acquire a polarized morphology and aggregate to form a migrating stream. view more (2008-12-01)
A potential targeting gene therapy for developing HCV
Gene therapy has emerged as a novel approach to combat HCV infection in the last few years. view more (2009-07-16)
Human immunodeficiency virus (HIV) treatment
Russian researchers have developed a medication capable of protecting against various human immunodeficiency virus (HIV) strains. Their effort has been supported by the International Scientific Technical Center. Intense search for efficacious human immunodeficiency virus treatment carried out by scientific laboratories worldwide has not yet... view more... (2004-01-30)
Plants that produce more vitamin C may result from UCLA-Dartmouth discovery
UCLA and Dartmouth scientists have identified a crucial enzyme in plant vitamin C synthesis, which could lead to enhanced crops. The discovery now makes clear the entire 10-step process by which plants convert glucose into vitamin C, an important antioxidant in nature. view more (2007-05-24)
E. coli persists against antibiotics through HipA-induced dormancy
Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science. view more (2009-01-16)
Scientists discover influenza's Achilles heel: Antioxidants
As the nation copes with a shortage of vaccines for H1N1 influenza, a team of Alabama researchers have raised hopes that they have found an Achilles' heel for all strains of the flu-antioxidants. view more (2009-10-30)
Eating soy protein helps control cholesterol
Soy protein helps lower total cholesterol, low-density lipid "bad" cholesterol and triglycerides, and slightly raises high-density lipid "good" cholesterol. view more (2006-09-21)
MGH researchers describe new way to identify, evolve novel enzymes
The intricate interplay of proteins and other chemicals that underlies most biological activities requires the participation of enzymes, specialized molecules that accelerate chemical reactions between molecules. view more (2007-08-16)
Penn study finds hyperbaric oxygen treatments mobilize stem cells
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body. view more (2005-12-29)
Cancer-causing gene discovery suggests new therapies
Scientists have discovered a novel way by which a much-studied cancer-promoting gene accelerates the disease. The finding suggests a new strategy to halt cancer's progress. view more (2009-01-26)
A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life. view more (2008-02-15)
Dr Lars Abrahmsén appointed Chief Scientific Officer of Affibody
Affibody today announced the strengthening of the management team by the appointment of Dr Lars Abrahmsén as Chief Scientific Officer. Lars Abrahmsén succeeds Stefan St'åhl, one of Affibody's founders. Professor St'åhl wished to return to academia, and has returned to his academic professorship, but remains as scientific... view more... (2004-01-27)
