'Fishy' clue helps establish how proteins evolve
Three billion years ago, a "new" amino acid was added to the alphabet of 20 that commonly make up proteins in organisms today. Now researchers at Yale and the University of Tokyo have demonstrated how this rare amino acid - and, by example, other amino acids - made its way into the menu for protein synthesis. view more (2009-01-28)
University of Sussex biologists estimate the pace of evolution
Scientists at the University of Sussex have provided the key to resolving a 30-year-old controversy in evolutionary biology: what proportion of the differences between similar species came about as a result of natural selection, and how many are just the result of 'random genetic drift'. In a paper in this week's issue of Nature (28 February),... view more... (2002-02-26)
New tool helps researchers identify DNA patterns of cancer, genetic disorders
A new tool will help researchers identify the minute changes in DNA patterns that lead to cancer, Huntington's disease and a host of other genetic disorders. view more (2009-05-19)
U of M study: Health food supplement may curb addiction of pathological gamblers
University of Minnesota researchers have discovered that a common amino acid, available as a health food supplement, may help curb pathological gamblers' addiction. view more (2007-09-12)
New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)
Scientists discover why plague is so lethal
Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology. view more (2008-05-05)
Meteorites delivered the 'seeds' of Earth's left-hand life
Flash back three or four billion years - Earth is a hot, dry and lifeless place. All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth. view more (2008-04-07)
A balancing act in Parkinson's disease: Phosphorylation of alpha-synuclein
Both genetic and pathologic data indicate a role for the neuronal protein alpha-synuclein in Parkinson disease. view more (2009-10-13)
Potassium limitation, ammonium toxicity and amino acid excretion in yeast
As a single-celled eukaryote organism, the yeast strain S. cerevisiae has some limitations in terms of how it can be used as a model for more complex multicellular eukaryotes. view more (2006-10-17)
Health: Improving the recognition of brain tumours
Researchers at the Institute of Nuclear Chemistry in Jülich have developed a short-lived, radioactive amino acid that delivers much more precise information on brain tumours and their structure than was possible in the past. By combining positron emission tomography (PET), a process that visualises the spread of radioactive substances in the... view more... (2005-05-04)
New technique helps researchers determine amino-acid charge
Measurements of the ion-current through the open state of a membrane-protein's ion channel have allowed scientists at the University of Illinois at Urbana-Champaign to obtain a detailed picture of the effect of the protein microenvironment on the affinity of ionizable amino-acid residues for protons. view more (2005-12-15)
Enzyme defect leads to hyperinsulinism
A recent study in the Journal of Biological Chemistry confirms that mutations in an enzyme called glutamate dehydrogenase can cause congenital hyperinsulinism. view more (2006-05-25)
Coding for arthropods-what's so special about insects and spiders?
The central dogma of molecular biology is that DNA makes RNA makes protein. This relies on a specific underlying code which relates given triplets of RNA nucleotides into specific amino acids. view more (2006-04-25)
Variants of 'umami' taste receptor contribute to our individualized flavor worlds
Using a combination of sensory, genetic, and in vitro approaches, researchers from the Monell Center confirm that the T1R1-T1R3 taste receptor plays a role in human umami (amino acid) taste. view more (2009-07-09)
MIT researchers unravel bacteria communication pathways
MIT researchers have figured out how bacteria ensure that they respond correctly to hundreds of incoming signals from their environment. view more (2008-06-13)
Repetitive motion speeds nanoparticle uptake
Newly published research by Rice University chemists and North Carolina State University toxicologists finds that repetitive movement can speed the uptake of nanoparticles through the skin. view more (2007-01-05)
Biomarker for age-related macular degeneration found
People who have elevated homocysteine in their blood, an amino acid that is a known biomarker for cardiovascular disease, may also be at an increased risk of developing age-related macular degeneration (AMD), according to a study in the January issue of the American Journal of Ophthalmology. view more (2006-01-05)
Ancient 'Out of Africa' migration left stamp on European genetic diversity, Cornell-led study finds
Human migration from Africa to Europe more than 30,000 years ago appears to have left a mark on the genes of Europeans today. view more (2008-02-21)
Amino acid may help treat patients with hair-pulling condition
The amino acid N-acetylcysteine appears to reduce symptoms of compulsive hair-pulling in patients with a condition known as trichotillomania. view more (2009-07-07)
Cornell researchers identify natural herbicide that controls weeds around some common lawn grasses
Certain varieties of common fescue lawn grass come equipped with their own natural broad-spectrum herbicide that inhibits the growth of weeds and other plants around them. view more (2007-11-09)
