Amino acids in nectar enhance butterfly fecundity: A long awaited link

The fascinating interactions between flowers and their pollinators have resulted in a spectacular diversity of plants. In order to entice pollinators such as bees, flies or butterflies to visit and successfully pollinate their flowers, plants have evolved intriguing mechanisms and attractants, of which nectar is best known. Thirty years ago, researchers discovered that nectars of flowers...

Conserved amino acids play both structural and mechanistic roles in sandwich-like protein

The question of whether amino acids in sandwich-like proteins are there to stabilize the structure or to speed up the protein-folding process is best answered by "all of the above," according to researchers at Rice University in Houston. This discovery, reported in today's issue of the Proceedings of the National Academy of Sciences, could benefit future research on treatments for disease...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

A pink, bacterial scum on the floor of an abandoned mine seems an unlikely place to study community development, but a biological breakthrough is allowing University of California, Berkeley, researchers to probe the give and take in this microbial mat. Last year, the UC Berkeley team joined with the Department of Energy's Joint Genome Institute to pluck out the genomes of the five dominan...

Study shows how retinoic acid enters a cell's nucleus

Cornell University researchers have revealed a process that has stumped scientists for many years: exactly how an acid derived from vitamin A enters a cell's nucleus, where it has strong anti-carcinogenic effects. Discovery of this basic transport mechanism opens a new door for future research on related compounds. The finding has important implications for the fight against cancer and ot...

Addition Of Folic Acid In Flour Proposed To Arrest Birth Defects In The UK

The Scientific Advisory Committee on Nutrition in the UK has said that many babies could be spared the trauma of being born with birth defects if folic acid were to be incorporated in flour. //Folic acid plays a vital role in reducing commonly found neural tube defects like the spina bifida. The Committee also maintained that medical termination of pregnancy could be avoided if this simpl...

Omega-3 fatty acids impair immunity

Taking large amounts of omega-3 fatty acids may be unwise for those with weakened immunity.Researchers at the University of Missouri, Columbia, have been studying omega-3s for many years now and know that one of their effects is to damp down inflammation. That's why fish oils - rich in omega-3s - often benefit those with arthritis, a painful inflammatory condition of the joints. Yet the i...

Protection mechanism of fatty acids for Cancer

A recent study by researchers at the University of Texas, have found out how omega-3 fatty acids might protect against colon cancer.Omega-3 fatty acids, which are found in fish oil, have long been known to protect against colon cancer.// They learned that the omega-3s block a molecule called protein kinase C beta II (PKCbII) - which is linked with abnormal cell division. In this study,...

Folic Acid helps Kids with Diabetes

New research shows folic acid supplements can help the hearts of children with diabetes. Researchers from Australia and New Zealand presented their findings over the weekend at the American Diabetes Association’s annual meeting in New Orleans. According to the American Diabetes Association, people with diabetes are two- to four-times more likely to have heart disease as compared to those...

Folic Acid Found To Be Beneficial For Stroke Patients

Folic acid helps women reduce their risk of birth defects. Now, new research shows the vitamin may also keep stroke patients alive.// Researchers say about 31,000 stroke-related deaths and about 17,000 heart disease-related deaths may have been prevented each year since fortification was implemented. Folic acid lowers homocysteine levels. People with higher homocysteine levels are at an...
