Relocated in small groups to experimental islands, lizards rapidly and repeatedly developed new chemical signals for communicating with each other. Free from the risk of predators and intent to attract potential mates, male lizards produce a novel chemical calling card, according to new research from Washington University in St. Louis.
TORONTO, ON - A team of researchers led by scientists at the University of Toronto (U of T) has delayed the onset of amyotrophic lateral sclerosis (ALS) in mice. They are cautiously optimistic that the result, combined with other clinical advances, points to a potential treatment for ALS in humans.
Commonly known as Lou Gehrig's disease, ALS is caused by the degeneration and loss of neurons that control muscles. There is no cure for ALS which currently affects between 2,500 and 3,000 Canadians.
KANSAS CITY, MO--Drug resistance is a major obstacle in cancer treatment--leading to relapse for many patients. In a new study, published online April 20, 2020, in Nature Cell Biology, researchers from the Stowers Institute for Medical Research, Children's Mercy Kansas City, and The University of Kansas Cancer Center report on a promising new strategy to overcome drug resistance in leukemia, using targeted doses of the widely-used chemotherapy drug doxorubicin.
April 20, 2020--New guidance is available for physicians who must go through a number of steps to provide a probable diagnosis of sarcoidosis - an inflammatory disease that affects the lungs, lymph glands, and other organs. The American Thoracic Society has published an official clinical practice guideline in which a panel of experts strongly recommended a baseline serum test to screen for hypercalcemia, a potentially serious disease manifestation, along with 13 conditional recommendations and a best practice statement to improve diagnosis and detection of sarcoidosis in vital organs.
Nearly half (49%) of New York City residents believe we should wait until after June 1st to reopen all non-essential businesses, while 19% said openings should take place between May 16-31. These findings are part of the sixth weekly city and statewide tracking survey from the CUNY Graduate School of Public Health & Health Policy (CUNY SPH), conducted April 17-19.
Three in five (60%) New Yorkers say the epidemic has made them feel more connected to fellow New Yorkers, and a similar number (61%) reported a feeling of solidarity with all Americans nationwide.
Virtual reality activates brain networks that increase your ability to identify with other people, according to new research published in eNeuro. The technology could become a tool in the treatment of violent offenders to empathize more with others.
What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight, suggesting that what was heralded as one of the first exoplanets to ever be discovered with direct imaging likely never existed.
Free-swimming cholera bacteria are much less infectious than bacteria in biofilms, aggregates of bacterial cells embedded in a sticky matrix that form on surfaces. This accounts for the surprising effectiveness of filtering water through cloth, such as a folded sari, which can reduce infections dramatically in places where the disease is endemic, despite the fact that individual cholera bacteria easily pass through such a filter.
HOUSTON - (April 20, 2020) - If you're on skis, you want to avoid avalanches. But when the right kind happen in your brain, you shouldn't worry. You won't feel them. They're probably to your benefit.
Scientists at Rice University's Center for Theoretical Biological Physics (CTBP) have simulated the mechanics of a complex network that helps give neurons their ever-changing structures. They found the complex, Arp2/3, may be largely responsible for the "avalanches" observed in the cells' cytoskeletal networks.
New Rochelle, NY, April 8, 2020--A novel method to predict the most promising targets for antiviral drugs or vaccines is based on the conformational changes viral glycoproteins go through during the process of recognition and binding to the host cell. This prediction method, which targets backbone hydrogen bonds for motifs with the highest free energy, is published in Journal of Computational Biology, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.
