Untangling the social lives of spiders

The idea of a complex spider society—in which thousands of spiders live, hunt, and raise their young together in a single colony—is unsettling to many of us. We are perhaps lucky then that this scene is relatively rare ...

Sturgeon genome sequenced

Sometimes referred to as the "the Methuselah of freshwater fish," sturgeons and their close relatives are very old from an evolutionary point of view. Fossils indicate that sturgeons date back 250 million years and have changed ...

Predation risk drives the evolution of the placenta

An international team of scientists led by assistant professor Bart Pollux from Wageningen University & Research has showed that predators are driving the evolution of more complex placentas. They studied populations of the ...

In cellular biology, mistakes can be good

Mistakes are rarely rewarded. Intuitively, one would imagine that a shoddy typist at an office who keeps generating typos would either quickly lose their job, or at least be overlooked for promotion. The idea that this person ...

Snake venom evolved for prey, not protection

It is estimated that every year, over 100,000 human deaths can be attributed to snakebite from the world's 700 venomous snake species—all inflicted in self-defense when the snakes feel threatened by encroaching humans. ...

Female toads seek a good man—even if he's another species

The one thing about species that most people probably remember from high school science class is that when it comes to sex, they generally stick to their own kind. Hybrids happen, but they are usually thought to be accidental, ...
