Global regulator for DNA trade needed

Amid growing concern that synthetic life sciences pose biosecurity and biosafety risks, scrutiny is increasing into the burgeoning DNA sequence trade. Research published today in the Bulletin of the Atomic Scientists, published by SAGE, looks at the necessity of a global regulator for DNA trade, and the significant barriers to creating one.

76% of Americans oppose cloning human embryos for research

As the U.S. Senate prepares to hold a hearing on human embryonic stem cell research (hESCR), a new public opinion poll shows that a plurality of Americans (47 percent) oppose federal funding of stem cell research that involves destroying human embryos, while only thirty-eight percent (38 percent) support such funding. The poll, conducted by ICR / International Communications Research, surveyed 1,006 adults September 8-14. It was commissioned by the Secretariat of Pro-Life Activities at the U.S. Conference of Catholic Bishops (USCCB).

New genetic analysis technique isolates culprit gene in families with inherited single-gene kidney diseases

A University of Michigan-led research team has identified a gene responsible in some families for a devastating inherited kidney disorder, thanks to a new, faster method of genetic analysis not available even two years ago. The success offers hope that scientists can speed the painstaking search for the genes responsible for many rare diseases and test drugs to treat them.

Researchers load biological molecules onto 'nanosprings'

Researchers at Oregon State University have reported the successful loading of biological molecules onto "nanosprings" - a type of nanostructure that has gained significant interest in recent years for its ability to maximize surface area in microreactors.

Simian immunodeficiency virus is at least 32,000 to 75,000 years old

An ancestor of HIV that infects monkeys is thousands of years older than previously thought, suggesting that HIV, which causes AIDS, is not likely to stop killing humans anytime soon, finds a study by University of Arizona and Tulane University researchers.

Research on signaling pathways may help to design therapy for neurodevelopmental disorders

Researchers at the Center for Neuroscience Research at Children's National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development-the epidermal growth factor receptor pathway and the Notch pathway-operate together to determine how many and which types of brain cells are created during growth and repair in developing and adult brains.

BCM-95 curcumin exhibits anti-inflammatory properties

Top researchers at the Gastrointestinal Cancer Research Lab at Baylor University Medical Center in Dallas are exploring the clinical applications of BCM-95®, a new patented extract of curcumin with unprecedented potency, and bioavailability.

Researchers find bariatric surgery reduces cardiovascular disease risk

Significant weight loss not only improves daily life of morbidly obese woman but also decreases the risk for cardiovascular disease (CVD). However, many people can not lose weight or can not maintain weight loss without help. Bariatric surgery is emerging as a valuable procedure to help morbidly obese individuals lose weight, as studies have shown; it can improve many health profiles and lower mortality. Now, researchers have found another positive impact of significant weight loss after bariatric surgery, it can significantly improve the lipoprotein profiles of women within a year following surgery.

Researchers decode key DNA in evolution of aging, development and fertility

UC Irvine researchers have deciphered how lowly fruit flies bred to rapidly develop and reproduce actually evolve over time. The findings, reported in the Sept. 15 online issue of Nature, contradict the long-held belief that sexual beings evolve the same way simpler organisms do and could fundamentally alter the direction of genetic research for new pharmaceuticals and other products.

Common Alzheimer's disease drug enhances learning of new skills

Research on a drug commonly prescribed to Alzheimer's disease patients is helping neuroscientists at the University of California, Berkeley, better understand perceptual learning in healthy adults.

Researchers reveal Prozac reactions to increase serotonin level

The response time to antidepressants, such as Prozac, is around three weeks. The adaptation mechanisms of the neurons to antidepressants has, until now, remained enigmatic. In particular, the researchers have revealed, for the first time, a sequence of reactions caused by Prozac at the neuron level, which contributes to an increase in the amounts of serotonin, a chemical "messenger" essential to the brain, and deficient in depressive individuals.

Scientists discover new drug target to improve radiation effectiveness for treating cancer

Scientists at Washington University School of Medicine in St. Louis have discovered a new drug target that could improve the effectiveness of radiation for hard-to-treat cancers.

New anti-pathogenic drugs render MRSA harmless without killing bacteria

Menachem Shoham, PhD, associate professor and researcher in the department of biochemistry at the Case Western Reserve University School of Medicine, has identified new anti-pathogenic drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) harmless by preventing the production of toxins that cause disease.

Fat-derived stem cells can aid breast reconstruction after mastectomy

Fat-derived stem cells can be safely used to aid reconstruction of breast tissue after mastectomy as long as there is no evidence of active cancer, according to researchers at the University of Pittsburgh School of Medicine.

Researcher discover enzyme for brain tumor malignancy

Tom Wurdinger, a Dutch researcher who is connected to Harvard (Boston) and the VUmc Cancer Center in Amsterdam, has discovered the enzyme playing a very important role in the return of malign brain tumor after surgery and radiation. By making this enzyme inactive, the cancer cell can become disorganized and blow itself up.
