By Newswise  Researchers develop a method to keep bots from using toxic language.  Researchers at the University of California San Diego have developed algorithms to rid speech generated by online bots of offensive language, on social media and elsewhere.  Chatbots using toxic language is an ongoing issue. But perhaps the most famous example is Tay, […]

By Newswise A little-known species of tropical bee has evolved an extra tooth for biting flesh and a gut that more closely resembles that of vultures rather than other bees.  Typically, bees don’t eat meat. However, a species of stingless bee in the tropics has evolved the ability to do so, presumably due to intense […]

(Newswise)–A study of woodland ecosystems that provide habitat for rare and endangered species along streams and rivers throughout California reveals that some of these ecologically important areas are inadvertently benefitting from water that humans are diverting for their own needs. Though it seems a short-term boon to these ecosystems, the artificial supply creates an unintended […]

(Newswise)–Comets that circle the Sun in very elongated orbits spread their debris so thin along their orbit or eject it out of the solar system altogether that their meteor showers are hard to detect.  From a new meteor shower survey published in the journal Icarus, researchers now report that they can detect showers from the […]

(Newswise)–The plant Aristolochia microstoma uses a unique trick: its flowers emit a fetid-musty scent that seems to mimic the smell of decomposing insects. Flies from the genus Megaselia (family Phoridae) likely get attracted to this smell while searching for insect corpses to mate over and lay their eggs in. When they enter a flower, they are imprisoned and first […]

(Newswise)–Wastewater provides a clue to virus transmission. In the ongoing COVID-19 pandemic, finding ways to improve testing has been key to addressing the spread of disease. While much effort has focused on testing individual people, scientists have begun to explore large-scale sampling of wastewater to understand patterns of viral transmission over larger areas. Researchers from the U.S. […]

(Newswise)–For the first time, scientists have shown that the bacterium that causes the tick-borne disease anaplasmosis interferes with tick gene expression for its survival inside cells and to spread to a new vertebrate host. Girish Neelakanta of Old Dominion University and colleagues report these findings in a study published July 2 in PLOS Genetics.  In […]

A new high-pressure ventilator developed by NASA engineers and tailored to treat coronavirus (COVID-19) patients Friday was approved by the Food and Drug Administration (FDA) for use under the FDA’s March 24 ventilator Emergency Use Authorization. Called VITAL (Ventilator Intervention Technology Accessible Locally), the device was developed by engineers at NASA’s Jet Propulsion Laboratory (JPL) […]

(Newswise)–A three-year, nearly $5 million award from NASA will allow researchers at the Sanford Stem Cell Clinical Center at UC San Diego Health, Sanford Consortium for Regenerative Medicine and their partners at Space Tango to develop a new integrated space stem cell orbital research laboratory within the International Space Station (ISS) and launch three collaborative […]
