Wild blacktip sharks can hear sounds from nearly 250 feet away and pinpoint where they come from; Florida experiments reveal how the predators locate sound underwater

Wild blacktip sharks may have a more sophisticated sense of hearing than scientists previously realised. A study by researchers at Florida Atlantic University found that free-swimming sharks can detect low-frequency sounds from as far as 74 metres, or roughly 243 feet, away and respond by turning sharply away from the source. The findings were reported … Read more

A student built a particle detector for just $100; the pocket-sized device can track invisible particles raining down from space at light’s speed; it is now being used in high-altitude balloon missions and major physics experiments

A student built a particle detector for just $100; the pocket-sized device can track invisible particles raining down from space at light’s speed; it is now being used in high-altitude balloon missions and major physics experiments

A device that can detect particles arriving from space does not necessarily require a multimillion-dollar laboratory. A compact detector developed by physicist Spencer Axani began as a low-cost student project and has since grown into a tool used for particle-physics research, education and high-altitude experiments. The University of Delaware detailed its latest developments in September, … Read more

Britain’s wasps are unusually scarce this summer; researchers cannot find enough for experiments, and the few seen are unusually small

Britain’s wasps are unusually scarce this summer; researchers cannot find enough for experiments, and the few seen are unusually small

Britain’s summer is missing one of its most familiar insects. Wasps that usually gather around outdoor food, patrol gardens and become increasingly noticeable in late summer appear unusually scarce in 2026. The shortage has become so pronounced that researchers are struggling to collect enough insects for laboratory experiments, while the few wasps being seen appear … Read more

'Second chance': Chimps used in hepatitis B experiments get comprehensive health checks in Liberia

File phot: A chimpanzee formerly used in research receives a comprehensive health check at a retirement sanctuary for chimpanzees, in Bapakwali, Liberia. Chimpanzees once used in hepatitis B vaccine experiments have undergone comprehensive health checks at a sanctuary in Liberia as part of long-term care aimed at giving the animals a chance to live out … Read more

In 1944, Polish priest Henry Denis endured Nazi malaria experiments at Dachau; after surviving the camp, he fulfilled his vow by building Our Lady of Fatima Shrine in Nebraska

A small roadside monument beside US Highway 34 in rural Nebraska carries the memory of a survival story that began inside the barracks of Dachau concentration camp. The Our Lady of Fatima Shrine, located on the grounds of St. Germanus Catholic Church in Arapahoe, was built to fulfil a solemn promise made by Father Henry … Read more
