British naturalist Charles Darwin (and maybe even his mushroom-hunting daughter) almost certainly would be excited about yet another exciting discovery in his beloved Galápagos Islands.

A college seafood forensics class investigated some fishy labelling. Breakthroughs, discoveries, and DIY tips sent every weekday. Sharks have been swimming in Earth's seas over 450 million years, but some struggling shark species may be ending up on grocery store shelves, in fish markets, and even sold online. Meat from shark species at risk of extinction is still available for sale in the United States, despite lawmaker's best efforts. "We found critically endangered sharks, including great hammerhead and scalloped hammerhead, being sold in grocery stores, seafood markets, and online," said Dr. Savannah J. Ryburn, a marine ecologist at University of North Carolina at Chapel Hill and co-author of a small study recently published in "Of the 29 samples, 93 percent were ambiguously labeled as'shark,' and one of the two products labeled at the species level was mislabeled." In the new study, a seafood forensic class at UNC bought 30 different shark products-19 raw steaks and 11 packages of shark jerky.

Breakthroughs, discoveries, and DIY tips sent every weekday. Great hammerhead sharks (Sphyrna mokarran)--the funny looking big fish with the rectangular shaped head--have an unusual feeding habit. Unlike many other sharks, who rely on small and numerous prey, great hammerheads eat other sharks. This diet is particularly high-risk, high-reward. For example, it takes a lot of energy to hunt a blacktip shark (Carcharhinus limbatus), but if successful, the hammerhead secures a high-energy meal.

With the rise of AI language models and tools like ChatGPT and Bard, we've heard warnings from people involved, like Elon Musk, about the risks posed by AI. Now, a group of high-profile industry leaders has issued a one-sentence statement: "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war." It was posted to the Center for AI Safety, an organization with the mission "to reduce societal-scale risks from artificial intelligence," according to its website. Signatories include OpenAI chief executive Sam Altman and Google DeepMind head Demis Hassabis. Turing Award-winning researchers Geoffrey Hinton and Yoshua Bengio, the godfathers of modern AI, also put their names to it.

Researchers captured drone footage of blacktip sharks evading a 12-foot-long hammerhead shark in Florida. Researchers have captured dramatic drone footage of blacktip sharks quickly evading a 12-foot-long hammerhead shark by swimming into shallow waters off Florida's coast. The drone footage captured by researchers with Florida's Atlantic University is the first evidence of large adult sharks using the shallows to flee predators. In the dramatic footage, the adult blacktop sharks are seen fleeing for shallow waters when faced with the hammerhead. The hammerhead shark was caught approaching the smaller blacktip sharks off the coast of Florida.

A drone flying over a Florida beach Saturday caught on camera a struggle between a fisherman and a massive hammerhead shark. The man was standing in shallow water on Panama City Beach during the encounter. Curtis Williams, a drone operator, captured the shark fighting against the man. A friend identified the fisherman as Per Eghoj, who was with the group Modern Day Outdoors. The organization films their adventures in a nature show aimed at attracting a new generation of outdoorsmen.
