This Week: Reading magma, predicting giant eruptions
In the News: Superbowl or stuporbowl? What's the story on brain damage?
Dive deep, and meet the flashlight squid — with a billion-bacteria light bulb. Meet bacteria that live in boiling water, and the immense variety of weirder-than-weird critters that live between grains of sand. Plus a highly selected bio-freak show…
Scientists thought wings were the first evidence of flight. But plenty of falling ants can glide back to “their” tree to avoid being devoured on the forest floor. If an ant’s brain and body are able to detect its position and change its flight path, is gliding the first flight?
78 million years ago, a pregnant predator of the Cretaceous ocean died and sank to the sea floor. Today, her fossil gives the first proof that plesiosaurs, one of the commonest and baddest marine reptiles of the era, did not lay eggs. It gave birth.
People with a genetic case of dwarfism in Ecuador don’t get cancer or diabetes, and a new study links that benefit to the genetic changes we see when calories are severely restricted. Could blocking growth hormone in adulthood lead to serious health benefits?
Horseradish, onions and caffeine all activate a group of chemical receptors that can trigger a pain signal. Turns out the same receptors exist in fruitflies, mussels, corals and mule deer. Why has this receptor survived a half-billion years? Because it protects against toxic chemicals – even if they taste good in small doses!
Do new species arise because so many niches are available in a new habitat? Or do they arise because newcomers have multiple talents for survival? A new study points to traits that enable success in the new location.
Animals spend a lot of energy avoiding toxic chemicals in their food. A new type of gene that does this in fruit flies reinforces the importance of reproduction in shaping evolution.
The theory of evolution is 150 years old, but forever young. We examine proofs for evolution, and four cool studies showing just how correct Charles Darwin was. Want to talk about silent crickets?
The color, vision and genetics of an African fish all vary depending on the clarity of its home waters. A new study suggests how species can form without geographic barriers.
Presto-chango! Caterpillar larva looks like a bird dung — and then like a leaf. New study points a finger at hormonal balance…
