Certain gut bacteria were linked to slower or faster biological aging. The communities of bacteria living in the gut may carry clues about how rapidly the body is aging. Researchers at the University of Hawaiʻi at Mānoa found that certain microbial patterns were associated with faster or slower biological aging, adding to evidence that gut [...]

Rising mantle temperatures and two heat surges may explain why some Hawaiian volcanoes grew exceptionally large. A 3500 km (2200 mile) trail of volcanoes records the Pacific plate’s slow passage over the Hawaiian hotspot. Instead of cooling through time as geologists have generally expected, the mantle plume beneath this chain appears to have warmed by [...]

Scientists have reported the first-ever live observations of the elusive goblin shark in its natural deep-sea habitat, capturing footage at two remote locations in the Central Pacific. Few sharks are as strange—or as elusive—as the goblin shark. With its elongated snout, protrusible jaws, and ancient lineage stretching back nearly 125 million years, the deep-sea predator [...]
