Dolphins off Australia’s east coast are using empty shells to trap prey, a behavior called shelling. The approach has been observed in Hervey Bay and Queensland’s Great Sandy Marine Park, with footage suggesting maternal transmission. Researchers say this adds to evidence of tool use in dolphins and may illuminate how humans evolved tool use.
A glacier collapse near the Nepal-Tibet border has triggered a devastating flood cascading through Nepal and China. Initial assessments have reclassified the event from a quake to a glacial debris flow, with authorities warning of possible secondary flooding as debris dams breach. Satellite imagery shows a glacier break, ice and rock tumbling into valleys, and rivers rising rapidly downstream.
A section of glacier near Langtang Lirung has collapsed and has sent a fast-moving surge of ice, rock and water through valleys of Tibet and northern Nepal. Rescue teams from Nepal, China and international partners have been searching for survivors; officials have reported hundreds dead and thousands missing while authorities warn of further flood risk from newly formed lakes.
