First study to show genetic adaptation of human fat metabolism

About 300 000 years ago humans adapted genetically to be able to produce larger amounts of Omega-3 and Omega-6 fatty acids. This adaptation may have been crucial to the development of the unique brain capacity in modern humans. In today's life situation, this genetic adaptation contributes instead to a higher risk of developing disorders like cardiovascular disease.

Consumption of long-chain omega-3 PUFAs lowers risk of colorectal polyps in women

New research finds that omega-3 polyunsaturated fatty acids (PUFAs) found in seafood (long-chain omega-3s) may reduce the risk of precancerous colorectal polyps in women, enhance the muscular benefits of strength training in older women and improve eye health after corneal surgery.

Abnormally low level of SMN protein linked to movement problems in spinal muscular atrophy

An abnormally low level of a protein in certain nerve cells is linked to movement problems that characterize the deadly childhood disorder spinal muscular atrophy, new research in animals suggests.

Fish oil not as beneficial for the heart as thought: Study

Fish oil, a combination of omega-3 fatty acids that has attracted much research on its effects on heart health. So far, the evidence has been inconclusive -- some studies have found fish oil has been major in preventing heart attacks, strokes and sudden cardiac death, while others have found fish oil has no benefits at all.

Novel anti-leukemia compound with little toxicity successfully treats zebrafish

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans - even those resistant to conventional therapies - according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Poultry producers still use FDA-banned antibiotics

In a joint study, researchers at the Johns Hopkins Bloomberg School of Public Health and Arizona State University found evidence suggesting that a class of antibiotics previously banned by the U.S. government for poultry production is still in use. Results of the study were published March 21 in Environmental Science & Technology.

Early-life bisphenol A exposure affects later-stage learning impairment

In testing the effects of the controversial chemical bisphenol A (BPA) on zebrafish, UWM scientist Daniel Weber found himself in familiar territory.

UV light-activated on-off switch for Morpholinos

University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers.

µ-PIIIA conotoxin can be effective in controlling cancer pain

Hidden in the mud, the cone snail Conus purpurascens lies in wait for its victims. It attracts its prey, fish, with its proboscis, which can move like a worm, protruding from the mud. Once a fish approaches out of curiosity, the snail will rapidly shoot a harpoon at it, which consists of an evolutionarily modified tooth. The paralyzed victim then becomes an easy meal. It takes the venomous cone snail about two weeks to digest a fish. During this time, its venomous harpoon is also replaced.

Brain games, exercise and diet help prevent cognitive slide

Exercising, eating a healthy diet and playing brain games may help you keep your wits about you well into your 80s and even 90s, advises a new book by researchers at George Mason University.

Scientists discover new serine protease: NSP4

Neutrophil granulocytes comprise important defences for the immune system. When pathogenic bacteria penetrate the body, they are the first on the scene to mobilise other immune cells via signal molecules, thereby containing the risk. To this end, they release serine proteases - enzymes that cut up other proteins to activate signal molecules. Scientists at the Max Planck Institute of Neurobiology in Martinsried have now discovered a new serine protease: neutrophil serine protease 4, or NSP4.

Study shows how fat cells can protect the body against diabetes

In a finding that may challenge popular notions of body fat and health, researchers at Beth Israel Deaconess Medical Center (BIDMC) have shown how fat cells can protect the body against diabetes. The results may lead to a new therapeutic strategy for preventing and treating type 2 diabetes and obesity-related metabolic diseases, the authors say.

Study shows how eating fast food is linked to increased risk of depression

A new study along the same lines as its predecessors shows how eating fast food is linked to a greater risk of suffering from depression. This study has been published in the Public Health Nutrition journal

Risk of botulism at California fish processing company

The U.S. Food and Drug Administration, in a complaint filed by the Department of Justice, is seeking to stop the processing and distribution of fish products at a California company because of a risk of botulism and other food hazards.

Basidiobolomycosis appears to be emerging in the Southwestern U.S.

An emerging fungal infection of the gastrointestinal tract that mimics cancer and inflammatory bowel disease appears to be emerging in the Southwestern United States and other desert regions, according to Mayo Clinic researchers in Arizona investigating the disease. The invasive fungus, Basidiobolus ranarum, is typically found in the soil, decaying organic matter and the gastrointestinal tracts of fish, reptiles, amphibians, and bats.
