From the deep -- Researchers find new species of sea anemone

...esearchers cruising for creatures that live in the deepest parts of the Pacific Ocean found a new species of sea anemone living in the unlikeliest of habitats ?the carcass of a dead whale. A marine biologist would say that discovering a new sea anemone isn't so unusual. But finding one that calls a dead wha...

Individual differences in a clock gene predict decline of performance during sleep deprivation

...out 50% more of their time in slow-wave sleep, the deepest form of sleep. Slow-wave sleep is a marker of sleep need, and it is known that carrying a sleep debt makes it very difficult to stay awake and perform at night. The findings highlight a possible role for clock genes in human sleep physiology and s...

Tracking sperm whales and jumbo squid

...and its large prey, the jumbo squid, are among the deepest divers in the ocean, routinely reaching depths of 3,000 feet or more. Now, in a new study, a team of marine scientists reports the successful tagging of sperm whales and jumbo squid swimming together off Mexico’s Pacific coast—the first time that ele...

The world's deepest dinosaur finding - 2256 metres below the seabed

...56 metres below the seabed, represents the world's deepest dinosaur finding. But it is by no means certain that the record-breaking knucklebone is a rarity down there in the abyss. In fact, the old North Sea land was once a huge area where big rivers meandered through dry plains. Now the landscape has been ...
