New report: Individual health insurance market failing consumers

The individual health insurance market is not a viable option for the majority of uninsured adults, a new report from the Commonwealth Fund finds. Seventy-three percent of people who tried to buy insurance on their own in the last three years did not purchase a policy, primarily because premiums were too high.

New research finds possible genetic link to cause of pregnancy loss and disorders

Scientists at the University of Tennessee, Knoxville, and Lawrence Berkeley National Laboratory have published new findings about a cause of a condition at the root of genetic disorders such as Down syndrome, pregnancy loss and infertility.It's called aneuploidy, meaning an abnormal number of chromosomes, and researchers found that if a mother's egg cell has a mutation in just one copy of a gene,...

Ovary removal may increase lung cancer risk

Women who have premature menopause because of medical interventions are at an increased risk of developing lung cancer, according to a new study published in the International Journal of Cancer. The startling link was made by epidemiologists from the University of Montreal, the Research Center of the University of Montreal Hospital Center and the INRS -- Institut Armand-Frappier.

Peptide linked to glucose metabolism and neuronal cell survival

A cellular protein that may prevent nerve cells from dying also helps to improve insulin action and lower blood glucose levels, according to a study by researchers at Albert Einstein College of Medicine of Yeshiva University in collaboration with scientists at University of California, Los Angeles.

Preimplantation genetic diagnosis may pose neurological risks

Preimplantation genetic diagnosis (PGD) has helped many couples conceive healthy children and is generally considered a safe practice. However, a new long-term analysis of PGD in mice suggests that this procedure may increase risks of weight gain and memory decline in adulthood.

Purer water made possible by Sandia advance

By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market.

Researchers turn cell phones into fluorescent microscopes

UC Berkeley researchers have developed a cell phone microscope that not only takes color images of malaria parasites, but of tuberculosis bacteria labeled with fluorescent markers. The latest milestone moves a major step forward in taking clinical microscopy out of specialized laboratories into field settings for disease screening and diagnoses.

Scientists capitalize on extended solar eclipse

Scientists at this observatory outside Hangzhou joined residents and tourists across China and India in observing the longest total solar eclipse in a century and probably the most-viewed ever.The moon's shadow traced a path across the world's two most populous countries before racing across the Pacific, providing a view of totality for five minutes and 36 seconds for scientists gathered here from...

Scripps research studies lead to a promising first-in-class drug candidate

Discoveries by Scripps Research Institute scientists have led to a promising new drug candidate -- the first in its class -- for patients with a genetic protein-misfolding disease. In results announced by the biopharmaceutical firm FoldRx Pharmaceuticals, Inc. today, the new drug tafamidis significantly halts disease progression for patients with a disease called Transthyretin (TTR) amyloid...

Study aims to induce recovery from ankylosing spondylitis

Chinese patients will soon have the opportunity to take part in a study of a novel therapy aimed at reversing the autoimmune disease, ankylosing spondylitis. Approximately 200 patients will be chosen to participate in a clinical trial that aims to merge the latest molecular discoveries published by the California non-profit Autoimmunity Research Foundation with the medical expertise of physicians...

Tiny diamonds on Santa Rosa Island give evidence of cosmic impact

Nanosized diamonds found just a few meters below the surface of Santa Rosa Island off the coast of Santa Barbara provide strong evidence of a cosmic impact event in North America approximately 12,900 years ago, according to a new study by scientists. Their hypothesis holds that fragments of a comet struck across North America at that time.

Twinkling nanostars cast new light into biomedical imaging

Researchers have created magnetically responsive gold nanostars that may offer a new approach to biomedical imaging. The nanostars gyrate when exposed to a rotating magnetic field, and can scatter light to produce a pulsating or "twinkling" effect. This twinkling allows them to stand out more clearly from noisy backgrounds like those found in biological tissue.

UC Davis study highlights work-life issues of female surgeons

Even with the demands of surgical careers, most surgeons would still choose their profession again. Women surgeons, however, are far more likely to postpone having children or to not have children at all and would prefer more flexibility in their work schedules, a national survey conducted by UC Davis researchers has found.
