The findings are hugely important as 6-10% of pregnant women are currently being treated for depression with antidepressants. Prof. Bérard, an expert in the fields of pharmaceutical safety during pregnancy, came to her conclusions after reviewing data covering 145,456 pregnancies. “The variety of causes of autism remain unclear, but studies have shown that both genetics and environment can play a role,” she explained...

If you’re pondering whether to buy a Galaxy smartphone or iPhone this holiday season, the dorsomedial prefrontal cortex (PFC) might ultimately determine your choice. Results of a new study suggest that this region of the brain plays a critical role in making choices.

“A big question is how and where value information is represented in the brain, and what goes into that representation,” says Dr. Fellows. “Our research confirmed what savvy marketers already know: the longer you look at one of two objects, the more likely you’ll choose that object even if you initially valued the other one more...

Scientists are testing a noninvasive alternative to lymph node biopsy for detecting early signs that melanoma skin cancer has spread. Patients currently undergo surgical removal, often involving a radioactive tracer, of these lymph nodes to screen for wayward cancer cells. But researchers say that in most cases this approach uncovers no sign of cancer spread while exposing patients to unnecessary risks...

Results from a long-term clinical trial conducted by cancer researchers show that combining radiation treatment with ‘suicide gene therapy’ provides a safe and effective one-two punch against the disease. The researchers compared 2 arms of patients and report high 5-yr overall survival rates of 97% and 94% respectively. That’s a 5 to 20% improvement for survival over historical studies.

66 prostate cancer patients participated in the Phase II clinical trial between 1999 and 2003 and were split into two groups...
