New gene variants present opportunities in nutrigenomics

A new study uncovers 11 gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) and triglycerides. The discovery opens up new opportunities for nutrigenomics researchers looking for links between diet and genetics that will optimize health and lower chronic disease risk.

Spinning Water Droplets Could Provide Insights into Black Holes, Atomic Nuclei

By magnetically levitating water droplets, and using a “liquid electric motor” technique to spin them, researchers can investigate how the droplets change shape. Rather than being just a curious experiment, the results could provide insights into systems that cannot be controlled in the laboratory, such as black holes and atomic nuclei.

Team refines cancer treatments to reduce potential nerve damage

While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility. To reduce the possibility of permanent nerve damage, UC Davis Cancer Center researchers have taken the lead in...

Turning over a new leaf for future energy supplies

A global energy supply based on biomass grown to generate electricity and produce fuel is a real possibility. According to Prof. Jürgen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany, it is both a sustainable and economical scenario, contrary to current thinking which suggests it is unrealistic. Their...

Vendee Globe route seen from above

(PhysOrg.com) -- Wind and wave data from ESA's Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race.

Obesity All In Your Head? Brain Genes Associated With Increased Body Mass

Is obesity all in your head? New research suggests that genes that predispose people to obesity act in the brain and that perhaps some people are simply hardwired to overeat. A genetic study of more than 90,000 people has identified six new genetic variants that are associated with increased Body Mass Index. Five of the genes are known to be active in the brain, suggesting that many genetic...

Immunity Stronger At Night Than During Day

A fruit fly's immune system can tell time, researchers have found, and how hard it punches back against infections depends on whether the fly is snoozing or cruising. The discovery could have implications for human health, too.

Low-carb Diets Can Affect Dieters' Cognition Skills

A new study shows that when dieters eliminate carbohydrates from their meals, they performed more poorly on memory-based tasks than when they reduce calories, but maintain carbohydrates. When carbohydrates were reintroduced, cognition skills returned to normal.

Promising New Drug Blocks Mutation In Bone Marrow Cancers

Researchers have found that an experimental drug successfully blocks an enzyme that causes some bone marrow cancers. The oral drug, called CYT387, was tested in mice as well as in human cells. In both cases, it blocked the growth of certain bone marrow cancers called myeloproliferative disorders, also referred to as...

Robotic Aircraft Designed For Weather Forecasting

At MIT, planning for bad weather involves far more than remembering an umbrella. Researchers in the Department of Aeronautics and Astronautics are trying to improve weather forecasting using robotic aircraft and advanced flight plans that consider millions of variables.

As Ice Melts, Antarctic Bedrock Is On The Move

As ice melts away from Antarctica, parts of the continental bedrock are rising in response -- and other parts are sinking, scientists have discovered. The finding will give much needed perspective to satellite instruments that measure ice loss on the continent, and help improve estimates of future sea level...

Effects Of Unconscious Exposure To Advertisements

Fads have been a staple of American pop culture for decades, from spandex in the 1980s to skinny jeans today. But while going from fad to flop may seem like the result of fickle consumers, a new study suggests that this is exactly what should be expected for a highly efficient, rationally evolved...

Meiosis: Cueing Up At The Meiotic Starting Line

Geneticists have been debating if meiosis requires only external or internal signals. Although earlier work revealed that an external cue from retinoic acid is needed, new research shows that embryonic germ cells must first express the Dazl gene in order to process the retinoic acid...
