Picture a shark as long as a bowling lane, with teeth bigger than your hand and a bite as powerful as a T. rex’s. This toothy predator is called Megalodon. It was the biggest shark that ever lived — and perhaps fortunately for us, it went extinct almost 3 million years ago.
The severely elongated head of a preserved skeleton found in Peru’s Atacama Desert in 2003 is so unusual that it initially prompted people to suggest that the diminutive body was that of an extraterrestrial.
Our solar system is in constant motion, with all eight planets — and dwarf planet Pluto — orbiting the sun. Most of those planets are visible from Earth, even to the...eye. If you track them in the sky night after night, you’ll notice that their position changes slightly; as they orbit the sun, they appear to move from west to east against a fixed backdrop of distant stars.
Two newfound species of bats recently discovered in Kenya are endearing, lemon-colored fuzzballs. But scientists aren’t interested in these bats just for their flashy colors; the animals also provide important clues about some very tangled branches in the bat family tree.
Scientists already knew that the lowest temperatures ever measured on Earth were on a frozen ice ridge in eastern Antarctica, near the South Pole. But they recently discovered that temperatures there can drop even lower than those previously measured.
Bedrock under Antarctica is rising more swiftly than ever recorded — about 1.6 inches (41 millimeters) upward per year. And thinning ice in Antarctica may be responsible.
T. rex may have been a highly successful predator, but it would have been terrible at licking stamps, lollipops or popsicles, thanks to a tongue that was likely fixed to the bottom of its mouth.
Imagine your worst day ever, preserved for eternity. That’s what happened to a very unlucky tick 100 million years ago.
Antarctica has lost 3 trillion tons of ice in the past 25 years, and that ice loss has accelerated rapidly over the last five years.
Giant viruses may invent genes and proteins found nowhere else on Earth, new research suggests.
