The most aggressive spider societies don't always thrive

The most aggressive spider societies don't always thrive

Science
March 25 (UPI) -- When colonies of the same spider species must compete for resources, the most aggressive spider society doesn't always thrive. New research suggests the success of a particular colony's success depends on the disposition of its neighbors. The African social spider Stegodyphus dumicola lives in colonies. Some spider colonies exhibit aggressive behavior, while others are more docile. African social spiders from different colonies don't compete face-to-face, but different colonies living in the plant compete for the same flying insects. Some colonies thrive, while others fail. "Consider the coordinated attacks of prides of lions or wolves, or the dazzling swirling behavior of starlings or schools of sardines," Jonathan Pruitt, an evolutionary biologist at the University of...

Promising new drug for aggressive stage IV breast cancer encounters setback

Health
Federal approval of a highly anticipated breast cancer drug was delayed by the Food and Drug Administration this week. The drug, sacituzumab govitecan, which is produced by Immunomedics, was previously designated a "breakthrough therapy" by the FDA “based on preliminary evidence that it demonstrates substantial improvement over existing therapies for a life threatening disease.” According to Michael Pehl, president and CEO of Immunomedics, the reason the medication was not approved for wide availability was due to “issues...exclusively focused on chemistry, manufacturing and control matters” and that “no new clinical or preclinical data need[s] to be generated.” He added, “We are going to request a meeting with the FDA as soon as possible &hell...
Scientists find genetic marker to diagnose aggressive prostate cancer

Scientists find genetic marker to diagnose aggressive prostate cancer

Health
Aug. 30 (UPI) -- Scientists have found a genetic marker for aggressive prostate cancer, which ultimately could lead to a better way to detect the disease. The genetic mutation is responsible for high risk of the aggressive form of cancer, according to researchers at the University of Turku in Finland, who published their findings Wednesday in the International Journal of Cancer. No test currently exists to diagnose aggressive prostate cancer at an early stage. Prostate cancer, the most common malignancy among men in the United States, will affect approximately 11.6 percent of men during their lifetime, according the National Cancer Institute. For the aggressive prostate cancer, the 10-year survival rate for men is 26 percent, according to The Prostate Center in England. Researchers studi...
