Phys.org / Soft-bodied sea slug reconfigures anatomy to simplify feeding control
Made entirely of muscle, with no rigid skeleton, muscular hydrostats like octopus arms, elephant trunks and human tongues can move in ways traditional mechanical systems cannot. Between crawling across the seafloor, picking ...
Phys.org / How 'pioneering pairs' of ospreys drive population recovery
A new study by Bournemouth University (BU) has found that faster recovery of osprey populations relies on a small number of ospreys that, unlike most, prefer to nest away from others of the same species. These birds have ...
Phys.org / Three days of Ontario wildfire smoke brought unhealthy air to 106 million person-days
Smoke from Canada's July wildfires exposed people across Canada and the United States to unhealthy, very unhealthy or hazardous air for nearly 106 million person-days between July 15–17. Over the peak impact period of July ...
Phys.org / Active supermassive black holes may help form massive planets
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...
Phys.org / CRISPR roadblocks: Scientists identify genes blocking gene therapy success
Like a delivery driver navigating crowded city streets, a gene-therapy-toting lipid nanoparticle faces a gauntlet of potential detours on its journey toward a cell's nucleus. First, there's entering the cell's plasma membrane; ...
Phys.org / Complex suicidal somersault behavior in male redback spiders may be explained by surprisingly simple genetics
The Australian redback spider (Latrodectus hasselti), a cousin of the North American black widow spider, is known to practice sexual cannibalism, which is somewhat common among spider species. However, the male Australian ...
Tech Xplore / From 'learning' to 'thinking,' AI language has long carried double meanings
