World's deepest shipwreck located

Victor Vescovo, the founder of exploration company Caladan Oceanic, and a team from EYOS Expeditions made six dives over eight days looking for the long-lost WW2 destroyer which was located on 22 June. It lies at a depth of 6,895 meters (22,621 feet), in the Philippine Sea, split in two and lodged on a slope.

Speaking to CNN, Vescovo called it an "honor" to find the ship, saying in a statement that locating it had given the team the chance "to retell her story of heroism and duty."

The emergence of TB in Peru likely came from marine mammals such as seals and sea lions.

Did marine mammals cause emergence of tuberculosis in the Americas?

DNA research has shown that Mycobacterium pinnipedii, which today causes tuberculosis (TB) primarily in pinnipeds, infected human populations living in the coastal areas of Peru prior to European colonisation

The earliest cases are found in Peru and northern Chile and are dated to ~700 CE, with possible cases occurring as early as 290 CE.

The researchers also discovered TB in the skeletons of people who lived nowhere near the coast some 400 to 1,000 years ago — a scenario incompatible with TB transmission directly from infected pinnipeds or their tissues.

Petition to Protect Great Hammerhead Sharks

The great hammerhead shark is categorized as “critically endangered” by the International Union for Conservation of Nature. That’s the designation just before “extinct in the wild.” The species is highly threatened with extinction.

To that end, the Center for Biological Diversity has submitted a petition urging the National Marine Fisheries Service to protect the great hammerhead shark under the Endangered Species Act.
