UF researchers develop improved gene therapy agent
Replacing one amino acid on the surface of a virus that shepherds corrective genes into cells could be the breakthrough scientists have needed to make gene therapy a more viable option for treating genetic diseases such as hemophilia, University of Florida researchers say. view more (2008-05-20)
UW-Madison study reveals new options for people with PKU
For people with the genetic condition known as phenylketonuria (PKU), diet is a constant struggle. They can eat virtually no protein, and instead get their daily dose of this key macronutrient by drinking a bitter-tasting formula of amino acids. view more (2009-03-31)
Huge virulence gene superfamily responsible for devastating plant diseases
A research team from the Virginia Bioinformatics Institute at Virginia Tech has identified an enormous superfamily of pathogen genes involved in the infection of plants. view more (2008-04-03)
Bone's material flaws lead to disease
The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease, stem from a genetic mutation that causes the incorrect substitution of a single amino acid in the chain of thousands of amino acids making up a collagen molecule, the basic building block of bone and tendon. view more (2009-08-05)
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)
Discovery may help defang viruses
Researchers may be able to tinker with a single amino acid of an enzyme that helps viruses multiply to render them harmless, according to molecular biologists who say the discovery could pave the way for a fast and cheap method of making vaccines. view more (2007-08-29)
A new wrinkle in evolution -- Man-made proteins
Nature, through the trial and error of evolution, has discovered a vast diversity of life from what can only presumed to have been a primordial pool of building blocks. view more (2007-05-23)
New technology illuminates protein interactions in living cells
While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods, according to a report in Nature Chemical Biology. view more (2007-11-12)
Epilepsy drug may help Alzheimer's patients
A popular epilepsy drug may also be beneficial in patients with Alzheimer's disease (AD), according to a new study to be published on October 27 in the Journal of Experimental Medicine. The anti-seizure drug valproic acid improved memory and reduced brain lesions in mice with an AD-like disease. view more (2008-10-27)
Scientists identify proteins that help bacteria put up a fight
Scientists have identified the role of two proteins that contribute to disease-causing bacteria cells' versatility in resisting certain classes of antibiotics. view more (2008-02-26)
Peptides-on-demand: McGill researcher's radical new green chemistry makes the impossible possible
McGill University chemistry professor Chao-Jun (C.J.) Li is known as one of the world leading pioneers in green chemistry, an entirely new approach to the science which eschews the use of toxic, petrochemical-based solvents in favour of basic substances like water and new ways of making molecules. view more (2009-02-25)
Fish vision discovery makes waves in natural selection
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. view more (2009-10-19)
NASA Scientists Find Clues to a Secret of Life
NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. view more (2009-03-18)
No Increased Risk of Miscarriage From Folic Acid Supplements (p 796)
Women who consume folic acid supplements around the time of conception are not at an increased risk of miscarriage, conclude authors of a population-based study published in this weke’s issue of THE LANCET. Although it is well known that folic acid supplements can reduce the risk of infant neural-tube defects (NTDs), its effects on other... view more... (2001-09-05)
Researchers identify new target in fight against obesity
University of Cincinnati (UC) scientists have identified a possible new target for treating obesity and diabetes. view more (2005-09-20)
Folic acid deficit increased risk of miscarriage in early pregnancy
Low levels of folic acid in plasma have been associated with an increased risk of miscarriage in a study published in Journal of the American Medical Association lately. On the other hand, no connection was found between high levels of folic acid and increased risk of miscarriage. In the US folic acid is added to flour to prevent pregnant women... view more...

Meteorites are rich in the building blocks of life, claims new research
Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today. view more (2008-03-14)
Evidence for warts treatments is weak
Apart from topical treatments containing salicylic acid, there is currently no clear evidence that any other treatments for warts are more effective, say researchers in this week’s BMJ. view more (2002-08-28)
Researchers Discover Master Metabolism Regulator with Links to Obesity, Heart Disease, and Malnutrition
Two biologists at Penn State have discovered a master regulator that controls metabolic responses to a deficiency of essential amino acids in the diet. view more (2007-02-07)
How left-handed amino acids got ahead: a demonstration of the evolution of biological homochirality in the lab
A chemical reaction that demonstrates how key molecules in the biological world might have come to be predominately left or right handed has been reported by scientists at Imperial College London. Ever since discovering that the building blocks of the biological world, such as amino acids and sugars, are distinctively left or right handed -... view more... (2004-06-21)
