AI headphones let wearer listen to a single person in a crowd, by looking at them just once
Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
Entomologist sheds light on 250-year-old mystery of the German cockroach
Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
High H5N1 influenza levels found in mice given raw milk from infected dairy cows
Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises questions about its potential risk in humans.
New advances in cancer viral immunotherapy
Researchers have developed a new strain of vaccinia virus, which can replicate in tumor cells while maintaining increased immunogenicity. Specifically, it can to induce so-called immunogenic cell death in tumor cells.
Controlling water, transforming greenhouse gases
Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
