Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remain in the brain that keeps on producing new neurons throughout life. However, the question arises as to whether these new neurons really support brain function? And if so, can we improve brain capacity by increasing the […]

As the demand for mental health services among college students nearly doubled over the last decade, advocates championed a common refrain: get students into treatment now. Students, parents and mental health experts feared that a student left untreated might harm themselves or others. Many universities responded by increasing counselors’ caseloads and funneling resources into urgent care. But a report released […]

UCLA and UC San Francisco life scientists have discovered a dramatic pattern of bone growth in female mice—research that could potentially lead to stronger bone density in women and new treatments for osteoporosis in older women. The researchers found that blocking a particular set of signals from a small number of neurons in the brain causes female, but not male, […]

Immunotherapies that take off the “brakes” on the adaptive anti-tumor response have worked well in melanoma and lung cancer but less so in breast cancers. That could change. A Vanderbilt team led by John Wilson, assistant professor of chemical and biomolecular engineering, and Rebecca Cook, associate professor of cell and developmental biology, activated innate immunity in breast cancer cells and […]

A new study indicates the prevalence rates of autism spectrum disorder (ASD) have now grown to 1 in 40, a jump from the rate of 1 in 65 published just two years ago. Indeed, ASD is now the fastest growing neurodevelopmental disorder in the U.S. Social deficits are core to a diagnosis of ASD. For people who have typical or […]

In American women, breast cancer is the most common cancer and the second-leading cause of cancer death. While routine screening helps to detect breast cancer, existing technology frequently identifies suspicious lesions that turn out not to be cancer. In fact, up to 80 percent of the biopsies performed reveal the suspicious areas are not cancerous. A team of scientists at […]

Cryptosporidiosis is the leading cause of waterborne diseases among humans in the United States, infecting almost 750,000 people each year, according to the Centers for Disease Control and Prevention. Globally in 2010, nearly 100,000 cases were fatal. The disease is of particular interest to Dr. Michael Riggs, a veterinarian and professor in the Department of Animal and Comparative Biomedical Sciences […]

A type of mosquito that transmits malaria has been detected in Ethiopia for the first time, and the discovery has implications for putting more people at risk for malaria in new regions, according to a study led by a Baylor University researcher. The mosquito, Anopheles stephensi, normally is found in the Middle East, Indian Subcontinent and China. Previous research shows […]

A clot in the retinal vein can lead to severe and irreversible loss of vision. In a report in the American Journal of Pathology investigators utilize a newly developed model of central retinal vein occlusion (CRVO) in mice that mimics many of the clinical features of CRVO in humans to study the pathologic effects of retinal occlusion and demonstrate the […]

Researchers at ETH Zurich have used trials with mice to shed light on signalling pathways that lead to thickened and less elastic blood vessels. They have developed a treatment approach for pregnant women with previously untreatable preeclampsia. One in 20 women around the world suffers from preeclampsia during pregnancy. It causes a rise in blood pressure and the kidneys cease […]
