Clamshell-shaped protein puts the 'jump' in 'jumping genes'

Scientists at Johns Hopkins report they have deciphered the structure and unusual shape of a bacterial protein that prepares segments of DNA for the insertion of so-called jumping genes. The clamshell shape, they say, has ...

Jumping spiders are masters of miniature color vision

Jumping spiders were already known to see in remarkably high resolution, especially considering that their bodies are less than a centimeter long. Now, researchers reporting in the Cell Press journal Current Biology on May ...

Spiders disguise themselves as ants to hide and hunt their prey

All spiders are predators, but most of them are small and have rudimentary defences against larger animals that in turn prey on them. Spiders have thus evolved a range of predatory behaviours that, at the same time, allow ...

Researchers record sight neurons in jumping spider brain

For the first time, a team of interdisciplinary researchers have made recordings of neurons associated with visual perception inside the poppy seed-sized brain of a jumping spider (Phidippus audax).

Human genome was shaped by an evolutionary arms race with itself

New findings by scientists at the University of California, Santa Cruz, suggest that an evolutionary arms race between rival elements within the genomes of primates drove the evolution of complex regulatory networks that ...

Timid jumping spider uses ant as bodyguard

A timid jumping spider uses the scent of ants as a secret weapon to save itself from becoming the somewhat soggy prey of the predatory spitting spider. The downside to this plan is that jumping spiders are also a favorite ...
