Genome of PURAC's lactic acid-producing micro-organism completed by Greenomics™
PURAC and Greenomics™ (Plant Research International B.V.) announced the completion of the whole-genome sequencing of a production strain of PURAC that produces high amounts of lactic acid. Greenomics™ conducted the shotgun cloning and high quality sequencing of the genome up to a zero-gap situation. The closed genome is accompanied by... view more... (2002-05-14)
Researchers discover how stealthy HIV protein gets into cells
Scientists have known for more than a decade that a protein associated with the HIV virus is good at crossing cell membranes, but they didn't know how it worked. view more (2008-03-18)
Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis. view more (2007-04-02)
Fox Chase Researchers Give Mutants Another Chance
Researchers at Fox Chase Cancer Center have demonstrated that it might be possible to treat genetic diseases, including some forms of cancer, by "rescuing" the misshapen, useless proteins produced by some mutant genes. view more (2009-02-12)
Food Fortification With Vitamin B12 In Addition To Folic Acid Could Reduce Risk Of Cardiovascular Disease (p 227)
Authors of a research letter in this week's issue of THE LANCET conclude that vitamin B12 in addition to folic acid should be used to fortify food to lower concentrations of the blood protein homocysteine, thereby potentially reducing the risk of cardiovascular disease. Mandatory fortification of grain foods with folic acid has been in place in... view more... (2002-01-17)
Researchers 'see' structure of open nicotinic acetylcholine ion channels
The neurotransmitter acetylcholine is an essential chemical communicator, carrying impulses from neurons to skeletal muscle cells and many parts of the nervous system. view more (2008-04-08)
Powerful mold-inhibiting bacteria patented
Bacteria that produce lactic acid have been used for thousands of years to preserve food. Some lactic acid bacteria also produce several other mold-inhibiting substances and are therefore of special interest to agriculture and the foodstuffs industry. This is demonstrated in a dissertation by Jörgen Sjögren from the Swedish University of... view more... (2005-04-08)
The sound of proteins
Biologists have converted protein sequences into classical music in an attempt to help vision-impaired scientists and boost the popularity of genomic biology. view more (2007-05-03)
St. Jude influenza survey uncovers key differences between bird flu and human flu
Scientists at St. Jude Children's Research Hospital have found key features that distinguish influenza viruses found in birds from those that infect humans. view more (2007-08-21)
UCLA AIDS Institute researchers find a peptide that encourages HIV infection
UCLA AIDS Institute researchers have discovered that when a crucial portion of a peptide structure in monkeys that defends against viruses, bacteria and other foreign invaders is reversed, the peptide actually encourages infection with HIV. view more (2007-05-11)
The shape of allergy - what makes an allergen an allergen
An enduring mystery for allergy researchers has been the unpredictable distribution of allergens in plants. For example, being allergic to birch pollen can predispose a person to allergy from distantly related plant foods such as celery, apple or soy. view more (2005-01-07)
Use of amino acid supplement following a heart attack provides no benefit, may be harmful
Use of the amino acid supplement L-arginine following a heart attack does not improve certain cardiac functions and measurements and may be associated with an increased risk of death. view more (2006-01-04)
Scientists discover the double life of proteins
Scientists at The Australian National University are a step closer to understanding the rare Hartnup disorder after discovering a surprising link between blood pressure regulation and nutrition that could also help to shed light on intestinal and kidney function. view more (2008-04-30)
Folic Acid Supplements Not Linked To Multiple Births (p 380)
Results of a Chinese population-based study in this week's issue of THE LANCET provide strong evidence that women who take folic acid supplements during pregnancy do not have an increased likelihood of having a multiple birth. Folic acid supplements are recommended for women of childbearing age to prevent neural tube defects-such as spina bifida... view more... (2003-01-29)
Fatty meals worsen the sensations of heartburn
A fatty meal worsens heartburn, but without increasing the amount of acid reflux from the stomach to justify the sensations, shows research in Gut. Eleven patients suffering from acid reflux, producing painful heartburn, took part in the study. After being given drugs to suppress their normal digestive acid production, and fasting, they were... view more... (2001-10-12)
Only one-third of women take vitamin to help prevent serious birth defects, survey finds
Only one-third of childbearing age women are taking a multivitamin containing the B vitamin folic acid daily to prevent serious birth defects of the brain and spine in their future babies, according to a decade of March of Dimes surveys. view more (2005-09-30)
ASU researcher may have discovered key to life before its origin on Earth
An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than... view more...

Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
Acid reflux is not just caused by lager and curry, but also our genes
Almost half the chance of developing acid reflux, which doctors refer to as GORD, may be down to our genes, and not just what we eat and drink, a twin study in Gut suggests. Acid reflux (gastro-oesophageal reflux disease) is one of the most common digestive disorders in the developed world. It is thought that up to one in five people suffers from... view more...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex
In a venture once thought to lie outside the reach of science, researchers from Harvard Medical School and Beth Israel Deaconess Medical Center have captured and sequenced tiny pieces of collagen protein from a 68 million-year-old Tyrannosaurus rex. view more (2007-04-13)
