West African lions don’t prefer national parks to hunting preserves

West African lions don’t prefer national parks to hunting preserves

Science
March 30 (UPI) -- Data from a massive wildlife camera survey suggests West African lions divide their time evenly between the region's largest national parks and the hunting preserves that surround them. There are an estimated 400 lions living in West Africa, and 90 percent of them are found in a protected complex called W-Arly-Pendjari, or the WAP Complex. The expanse comprises five national parks and 14 hunting concessions in Burkina Faso, Niger and Benin -- some 10,200 square miles of habitat. Inside the parks, the lions are protected and face fewer human pressures, but in the hunting preserves, the lions can be killed. When scientists set out to document their distribution and movement patterns within the WAP Complex, they expected to find that lions avoided hunting concessions when ...
Whole-brain radiation procedure preserves cognitive function in trial

Whole-brain radiation procedure preserves cognitive function in trial

Health
Oct. 23 (UPI) -- Patients' cognitive functions can be preserved if the hippocampus portion of the brain is avoided during radiation, according to the results of a clinical trial. Researchers compared hippocampal-avoidance radiotherapy with traditional whole-brain radiation for patients with brain metastases. They presented their practice-changing findings Tuesday at the American Society for Radiation Oncology Annual Meeting in San Antonio and are in the process having them published in an academic journal. The hippocampus, which is located under the cerebral cortex, is the part of the brain associated with cognitive function, including memory. In brain metastases, cancer cells have spread to the brain from primary tumors in other organs. Brain metastases affect up to 45 percent of adults...
