A 3-foot-long mammoth tusk hidden on the ocean floor could offer clues about the ancient creatures

Members of the science team at the Monterey Bay Aquarium Research Institute observe the mammoth tusk.Darrin Schultz © 2021 MBARI Scientists discovered a 3-foot-long mammoth tusk roughly 10,000 feet below the ocean's surface. The deep sea is ideal for preserving remains, though mammoth fossils rarely wind up there. The tusk belongs to a young female mammoth. Scientists are using it for clues about how she lived.

'Vulture bees' have quit pollen to feed their babies rotting meat — a mystery to scientists

Vulture bees in Costa Rica dining on raw chicken bait.Quinn McFrederick/UCR "Vulture bees" have evolved to eat meat instead of relying on pollen like other bees. Scientists hung raw chicken in Costa Rica and watched vulture bees fill their leg pouches and stomachs with it. They found acid-producing microbes in the bees' guts. Acid helps vultures and hyenas digest carrion. A group of scientists biked around Costa Rica's tropical forests, hanging chunks of raw chicken from the trees, in...

1 chart shows how quickly a booster shot can improve immunity, with some extra protection in just a few days

Nicole Fahey, six months pregnant, receives her Pfizer COVID-19 vaccine booster shot in Los Angeles.Gary Coronado / Los Angeles Times via Getty Images Booster shots are being offered to all US adults. Studies suggest boosts can improve protection against symptomatic COVID-19, at least temporarily, with benefits beginning to accrue after a few days. It's unknown how durable booster shot protection will be, but scientists are hopeful. Two shots are good, but when it comes to preventing symp...

Scientists propose first steps toward creating life on Mars

The moment humankind stepped out from our caves and gazed upon the night sky with curiosity and wonder, our ancestors set into motion a chain of events that will almost certainly end up with humans walking on Martian soil. And, if you believe the current hype, that day could come in the next couple of decades. NASA has every intention of sending a crewed mission to the red planet sometime in the 2030s. In the meantime, those of us who remain stuck here on Earth are left to wonder what such an ac...
