Rare egg producing stem cells in women’s ovaries discovered

It was known till now that women were born with all the eggs they'll ever have. But now Harvard scientists have found that ovaries of young women harbor very rare stem cells capable of producing new eggs. The researchers feel that harnessing those stem cells might one day lead to better treatments for women left infertile because of disease or age.

H2S transforms dental pulp stem cells into liver cells

Japanese scientists have found that the odorous compound responsible for halitosis - otherwise known as bad breath - is ideal for harvesting stem cells taken from human dental pulp.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.

Ovarian cancer subtype may be susceptible to 'anti-angiogenic' drugs

Scientists at Dana-Farber Cancer Institute have identified a subtype of ovarian cancer able to build its own blood vessels, suggesting that such tumors might be especially susceptible to "anti-angiogenic" drugs that block blood vessel formation.

Study shows how malaria parasite changes into banana form before sexual reproduction

New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine or drug development and may explain how the parasite evades the human immune system.

Komen's Brinker apologizes for 'how we mishandled this situation'

In her first public statement since her organization reversed a decision to stop donating to Planned Parenthood, Nancy Brinker, the founder of Susan G. Komen for the Cure, said that "I made some mistakes" in the case, which swelled into a massive controversy. Brinker, in a letter to Washington Post columnist Sally Quinn, also noted that many commentators had blamed "culture wars" for the intensity of the criticism over the foundation's cutoff of funding.

UofL to receive Grand Challenges tuberculosis biomarkers grant

The University of Louisville announced today that it will receive a tuberculosis (TB) biomarkers grant through the Bill & Melinda Gates Foundation's Grand Challenges in Global Health program, an initiative which seeks to overcome persistent bottlenecks in creating new tools that can radically improve health in the developing world. James E. Graham, Ph.D., associate professor of microbiology and immunology at the UofL School of Medicine, will pursue an innovative research project to identify and validate TB biomarkers, titled "Disposable Sampling Plate and Breath Test to Identify Patients with Active Tuberculosis."

Karolinska Institutet to study fundamental causes of diabetes

The Swedish medical university, Karolinska Institutet, has received a grant of 1.6 million Euro from the Stichting af Jochnick Foundation for research into the fundamental causes of diabetes. The grant will make it possible to use unique methods to study how the release of insulin is regulated in living organisms - and this will create new opportunities for developing more effective drugs against diabetes.

Scientists capture finest nerve cell details in living mouse brain

To explore the most intricate structures of the brain in order to decipher how it functions - Stefan Hell's team of researchers at the Max Planck Institute for Biophysical Chemistry in G-ttingen has made a significant step closer to this goal. Using the STED microscopy developed by Hell, the scientists have, for the first time, managed to record detailed live images inside the brain of a living mouse.

Urine-based biomarkers may lead to development of test for high-risk prostate cancer

Initial results of a multicenter study coordinated by researchers at Fred Hutchinson Cancer Research Center indicates that two investigational urine-based biomarkers are associated with prostate cancers that are likely to be aggressive and potentially life-threatening among men who take a "watchful waiting," or active-surveillance approach to manage their disease.

Fluorescence microscopy reveals 3-D picture of myoV's transport capacity

A new study in the Journal of General Physiology uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track.

Survey: Percentage of Americans who lack health coverage rose for fourth straight year

The percentage of Americans lacking health insurance coverage rose for the fourth straight year in 2011 to 17.1 percent, a new survey showed Tuesday. The climb has been steady since Gallup began tracking whether adults have health insurance in 2008. Four years ago, only 14.8 percent of adults lacked health insurance.

Minuscule amounts of ethanol can double C. elegans' life span

Minuscule amounts of ethanol, the type of alcohol found in alcoholic beverages, can more than double the life span of a tiny worm known as Caenorhabditis elegans, which is used frequently as a model in aging studies, UCLA biochemists report. The scientists said they find their discovery difficult to explain.

Cedars-Sinai's annual Brainworks program to take place on Feb. 13

Taking turns gazing into a surgical microscope, 130 seventh- and eighth-graders from Los Angeles area schools will see a phantom skull and perform virtual surgery - and many could catch a glimpse of the future.

Researchers reveal role of micronuclei in cancer process

They are the Robinson Crusoes of the intracellular world -- lone chromosomes, whole and hardy, stranded outside the nucleus where their fellow chromosomes reside. Such castaways, each confined to its own "micronucleus," are often found in cancer cells, but scientists haven't known what role, if any, they play in the cancer process.
