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)
Pitt researchers describe molecular '2-step' leading to protein clumps of Huntington's disease
In a paper published in the early online version of Nature Structural and Molecular Biology, researchers at the University of Pittsburgh School of Medicine deconstruct the first steps in an intricate molecular dance that might lead to the formation of pathogenic protein clumps in Huntington's disease, and possibly other movement-related... view more...

Blood pressure enzyme can have tumor-sensing role
By increasing production of a blood pressure-regulating enzyme in mice, researchers have found they can enhance the mouse immune system's ability to sense tumor growth. view more (2008-04-08)
Iowa State University researcher discovers key to vital DNA, protein interaction
A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances." view more (2009-11-11)
FATTY FISH CONSUMPTION COULD REDUCE PROSTATE CANCER RISK
Consumption of fatty fish such as salmon, herring, and mackerel could reduce the risk of prostate cancer, report the authors of a research letter in this week's issue of THE LANCET. Essential fatty acids - especially omega-3 fatty acids contained in large amounts in fatty fish - have previously proved to inhibit the growth of prostate cancer... view more... (2001-05-31)
Newly improved NIST reference material targets infant formula analysis
Chemists at the National Institute of Standards and Technology (NIST) have issued a new certified reference material-a standardized sample backed by NIST-for determining the concentrations of vitamins, minerals and other nutrients in infant and adult nutritional formula and similar products. view more (2009-08-27)
Changing environment organizes genetic structure
What is the fundamental creative force behind life on Earth" It's a question that has vexed mankind for millennia, and thanks to theory and almost a year's worth of number-crunching on a supercomputer, Rice University physicist and bioengineer Michael Deem thinks he has the answer: A changing environment may organize the structure of genetic... view more...

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)
University of Alberta researchers report breakthrough in lowering bad cholesterol, fatty acid levels
U of A medical researchers have found a way to reduce the amount of bad cholesterol and fatty acids that end up in the blood from food the body metabolizes, a key discovery that could lead to new drugs to treat and reverse the effects of Type 2 diabetes and heart disease related to obesity. view more (2008-01-10)
Bio-archaeologists pinpoint oldest Northern European human activity
Scientists at the University of York used a 'protein time capsule' to confirm the earliest record of human activity in Northern Europe. view more (2005-12-15)
High level of cardiac biomarker may help predict risk of CVD events in patients with heart disease
A blood test for patients with coronary heart disease could help predict their risk for subsequent cardiovascular events or death. view more (2007-01-10)
Protein Sequences: Not So Predictable After All
Scientists have believed for decades that the sequencing of the human genome would automatically yield the sequences of proteins, the functional products of genes, and thus lead to the unraveling of the mechanisms behind human cell biology and disease. However, a paper published in Science today by the Ludwig Institute for Cancer Research (LICR)... view more... (2004-03-01)
Feedback loop found that could forestall liver disease
Researchers at UT Southwestern Medical Center have discovered that the small intestine communicates with the liver to control the production of bile acids-a finding that has great medical implications in treating people at risk for certain types of liver disease. view more (2005-10-12)
New understanding of how big molecules bind will lead to better drugs, synthetic organic materials
Biological and medical research is on the threshold of a new era based on better understanding of how large organic molecules bind together and recognise each other. view more (2008-02-22)
Redesigned protein accelerates blood clotting
Researchers have made several, subtle changes in the structure of a key protein, dramatically increasing its ability to drive blood clotting, according to a study published in a December edition of the Journal of Thrombosis and Haemostasis. view more (2008-12-23)
Getting wise to the influenza virus' tricks
Influenza is currently a grave concern for governments and health organisations around the world. The worry is the potential for highly virulent bird flu strains, such as H5N1, to develop the ability to infect humans easily. New drugs and vaccines to halt the spread of the virus are badly needed. view more (2008-05-05)
Fatty fish protects against cancer
If you want to avoid cancer of the kidneys, a new major study from Karolinska Institutet in Sweden shows that eating salmon or other kinds of fatty fish a few times a month would be one good way to go about it. view more (2006-09-20)
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)
Bile acids, receptor key in regenerating livers
Bile must have been the most important thing in medicine for the physicians of ancient Greece and Rome. Yellow bile and black bile are half of the four humors that they believed made up the body, along with blood and phlegm. view more (2006-04-14)
Typical North American diet is deficient in omega-3 fatty acids
New research from the Child & Family Research Institute shows the typical North American diet of eating lots of meat and not much fish is deficient in omega-3 fatty acids and this may pose a risk to infant neurological development. Omega-3 fatty acids are unsaturated fats found in some fish such as salmon and herring and in smaller amounts in... view more... (2008-03-10)
