Visual cortex contains neurons that are sensitive to viewing angle

Mistakes made by human subjects in identifying the facing direction of faces, cars or meaningless objects have yielded evidence that the brain contains nerve cells, or neurons, whose job is to encode the viewing angle of objects. It is well known that certain neurons respond to color, motion, edges and other aspects of our environment.

Discovery gives clinicians new targets for making existing therapies more effective and developing drugs to inhibit the growth of cancers

A team of researchers at the University of Alberta in Edmonton and the Samuel Lunenfeld Research Institute in Toronto have discovered how a key enzyme involved in repairing DNA is put together and how it works--a development that opens up new therapies for making cancer cells more vulnerable to attack.

Abnormal brain structure tied to spatial, numerical thinking problems when children lack part of chromosome

Certain genetic diseases affect children's educational abilities in a distinctive pattern: impairing their numerical abilities more than their verbal skills. New research sheds light on this split in abilities by investigating how differences in brain structures may influence how the mind works.

Important player in the development of colon cancer

Cancer growth is a long, complex, multi-stage process involving a variety of different "players." This complexity is part of the difficulty facing cancer researchers. Meanwhile, each discovery or identification of a new "player," or previously unknown stage in the process, offers new opportunities for blocking the disease.

Researchers turn fatal brain cancer into treatable disease for children

Some children with a rare brain tumor that is considered almost universally fatal can be saved if they receive radiation therapy followed by tandem (given one after the other) cycles of high-dose chemotherapy.

Way to detect early signs of testicular cancer

Danish researchers have discovered a way to detect early signs of testicular cancer before it has started to spread. Their findings are the first step towards developing a simple screening test for men at risk of the disease.

Researchers identify first known mutation to occur in lung cancer patients who have never smoked

Dr.Adi Gazdar, professor of pathology in the Nancy B. and Jake L. Hamon Center for Therapeutic Oncology Research and senior author of the study in today's issue of the Journal of the National Cancer Institute, explains that the findings may show why certain lung cancer patients respond dramatically to a specific form of targeted therapy while others have little or no response.

alpha-defensin-1, a protein found in immune cells, can control HIV infection

Theresa Chang and colleagues at Mount Sinai School of Medicine analyzed how alpha-defensin-1 inhibits HIV infection in white blood cells (CD4+ T cells). Defensins have been shown to have anti-HIV activity. The body attempts to protect itself from HIV infection via the innate immune system.

Health professionals should show more empathy - essential to healing relationships

Business scholars for more than 20 years have explored the concept of 'emotional labor,' or the management of emotions to present a certain image in service workers. Now, researchers from the University of Washington Business School and Group Health Cooperative have teamed up to explore how the concept can be applied to the medical profession.
