DNA-based assembly line for precision nano-cluster construction

Building on the idea of using DNA to link up nanoparticles - particles measuring mere billionths of a meter - scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction.

Discovery of mechanism of neurodegeneration in Alzheimer's disease

Tiny, toxic protein particles severely disrupt neurotransmission and inhibit delivery of key proteins in Alzheimer's disease, two separate studies by Marine Biological Laboratory (MBL) researchers have found.

Nanoparticles in cosmetics may be harmful to the environment

Using aquatic microbes as their "canary-in-a-cage," scientists from Ohio have reported that nanoparticles now being added to cosmetics, sunscreens, and hundreds of other personal care products may be harmful to the environment.

Male circumcision reduces risk of herpes simplex virus type 2 and human papillomavirus

Heterosexual men who undergo medical circumcision can significantly reduce their risk of acquiring two common sexually transmitted infections - herpes simplex virus type 2 (HSV-2), the cause of genital herpes, and human papillomavirus (HPV), which can cause cancer and genital warts, according to a report in the March 26 issue of the New England Journal of Medicine (NEJM).

Twin nanoparticle shown effective at targeting, killing breast cancer cells

A team of investigators at Brown University has developed a novel way to treat a class of breast cancer cells. The team has created twin nanoparticles that specifically targets the Her-2 tumor cell and unload a cancer-fighting drug directly into it. The result is a boost in antitumor activity while minimizing side effects. The findings of this study have been published in the Journal of the American Chemical Society.

Fructose metabolism by the brain increases food intake and obesity

The journal Biochemical and Biophysical Research Communications (BBRC), published by Elsevier, will publish an important review this week online, by M. Daniel Lane and colleagues at Johns Hopkins, building on the suggested link between the consumption of fructose and increased food intake, which may contribute to a high incidence of obesity and Type 2 diabetes.

Researchers decipher blood stem cell attachment, communication

Researchers at the National Institutes of Health have deciphered a key sequence of events governing whether the stem cells that produce red and white blood cells remain anchored to the bone marrow, or migrate into the circulatory system.

Rockefeller neuroscientist applies basic science to health care reform

A self-described "molecular sociologist" is extending his basic research to the national policy debate on health care reform. Bruce McEwen, head of the Laboratory of Neuroendocrinology, led a panel of scientific experts last month at the Institute of Medicine's Summit on Integrative Medicine and the Health of the Public. The Institute is the most prominent independent medical advisory board in the country and will release a report from the conference in November, as Congress is likely to be considering major health care legislation.

Discovery of major new risk factor for melanoma in young women

Researchers may have found a more potent risk factor for melanoma than blistering sunburns, freckling, or family history of the deadly skin disease.

Inconsistent performance speed among children with ADHD may underlie how well they use memory

Children with attention-deficit hyperactivity disorder (ADHD) show more variable or inconsistent responses during on 'working' or short-term, memory tasks when compared with typically developing peers, a study by UC Davis M.I.N.D. Institute Julie Schweitzer has found.

Discovery of new molecular mechanism for the processing of endocannabinoids

Dale Deutsch, Ph.D., Professor of Biochemistry and Cell Biology at Stony Brook University and colleagues discovered a new molecular mechanism for the processing of endocannabinoids, brain compounds similar to THC, the active ingredient in marijuana, and essential in physiological processes such as pain, appetite, and memory.
