Scientists have discovered a new way of measuring the potential success rate of an embryo before it is transferred back into the womb during in vitro fertilization (IVF). According to the findings, the fluid within a woman's ovaries that surrounds the egg or oocyte holds metabolic information that can improve predictions on which embryo is more likely to lead to pregnancy.

For the first time, researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those caps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report.

Researchers have discovered how the "guardian of the genome'' oversees quality control in the production of sperm -- and perhaps in many other cells as well.

Scientists have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were 'so to say' vaccinated with their own cells. The immune system of the testees was better than before in attacking and suppressing the virus, the scientists have reported.

One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now a researcher has discovered a compound that could help put the immune system back in the hunt.

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate. While researchers hope the work will one day lead to a way to make anti-HIV drugs more effective by increasing their potency against the virus, they're also excited about its implications for our knowledge of other pathogens, such as herpes viruses.

A novel discovery reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus’ progression to AIDS.

Curcumin, an active component of the Indian curry spice turmeric, may help slow down tumor growth in castration-resistant prostate cancer patients on androgen deprivation therapy, a new study suggests.

In a large analysis of men participating in a prostate drug trial, researchers found a significant correlation between coronary artery disease and prostate cancer, suggesting the two conditions may have shared causes.
