Spiders

A new understanding of the way tarantula toxins shut down electrical signals in the spider’s prey has given scientists hope of recreating this effect, but in a positive way through advanced drugs that treat chronic pain.

Spider venom isn’t normally something you want in your body, but there might be exceptions. Australian researchers have identified two peptides from tarantula venom that show promise in blocking organ pain, working particularly well in mice with IBS.

Nanofibers have found use in numerous applications, ranging from lightweight car parts to high-strength materials. Now, thanks to a new understanding of a certain group of spiders, they may soon be easier to work with.

Opioid pain relievers not only produce potential side effects such as nausea and constipation, but they can also be highly addictive. Australian scientists have therefore created what could be a better medication, that is made using tarantula venom.

A super-keen 22-year-old Australian spider enthusiast has identified and named 7 new species of Peacock Spider. Famed for their psychedelic color schemes and funky courtship dances, they're a visual feast for arachnophiles and arachnophobes alike.

Spiders may seem like they sit on top of the food chain in the bug world, but they’re vulnerable to an even worse fate: parasitic wasps that infect and essentially “zombify” them. And now, researchers have discovered 15 new species of these wasps.

The ability of jumping spiders to correctly judge the distance of its leaps could mean big things for imaging in small devices, with scientists at Harvard tapping into these skills to develop a new kind of ultra-compact depth-perception sensor.

A new substance is claimed to combine strength and toughness, by mixing wood fibers with spider silk.

Spider-Man's "spidey-sense" isn't purely fiction – spiders have tiny, sensitive hairs on their legs that help them avoid predators or hunt prey. And now, engineers at Purdue University have developed similar sensors for autonomous cars or drones.

A fungus is known to control the minds and bodies of ants to help itself reproduce, but it’s not the only insect to use the morbid tactic. Certain species of parasitic wasps have been found to “zombify” spiders, and now a new review paper has examined exactly how the insects pull off this feat.

It’s no secret that spider silk is one of nature’s most incredible materials. Now scientists have discovered a weird new ability. A team led by MIT has found that when exposed to a certain level of humidity, spider silk suddenly shrinks and twists, which could make it useful in artificial muscles.

​Many times, when new species are discovered, the characteristics that set them apart can only be appreciated by scientists. That isn't the case with the Ceratogyrus attonitifer tarantula, however – the thing has a long, soft horn protruding out of its back, and nobody knows why it's there.
