How do we know how old sharks are? A new University of Georgia study looks at their DNA
4+ day, 5+ hour ago (238+ words) September 8, 2026 4:01 PM LISTEN: A new study from the University of Georgia looks to estimate the age of sharks by analyzing their DNA using a blood sample. GPB's Chase McGee reports. Previously, if you wanted to know how old a shark…...
Sharks are now carrying ocean sensors through storm-feeding waters and hurricane forecasters are paying close attention as offshore wind farms reshape the data landscape beneath Atlantic hurricanes
1+ week, 10+ hour ago (386+ words) Somewhere beneath the Atlantic, a shark is doing the work of a weather buoy — gliding through the warm, deep water that quietly powers hurricanes. It carries a sensor. It goes where researchers rarely can. Forecasters have long known that what…...
Greenland sharks can live so long that the oldest may have been swimming when the First Fleet reached Australia. Now researchers examining sharks more than a century old have found remarkably intact retinas—and DNA-repair genes that may preserve their sight through centuries in the Arctic’s dim depths.
1+ week, 4+ day ago (1488+ words) The evidence comes from intact retinal layers, active rod genes and blue-sensitive pigment, while the proposed role of DNA repair remains a mechanism to test rather than a proven longevity switch. By Natural History · Edited by Lachlan Brown Published September…...
Cameras on whale shark fins caught them feeding as deep as 68.8 metres
2+ week, 16+ hour ago (322+ words) Camera tags went onto ten whale sharks at Ningaloo Reef and five came back with usable video. In 22 hours and 27 minutes of it, researchers scored 13 behaviours, eight of them feeding, and the deepest feeding they filmed reached 68.8 metres. Those eight…...

What Shark DNA Can Teach Us About The Biology Of Aging
2+ week, 6+ day ago (1214+ words) What if we could estimate a shark’s age from a small blood sample rather than counting growth rings in its vertebrae? New research on zebra sharks has developed an “epigenetic clock” that can predict age with surprising accuracy, using changes…...
