As part of an effort to understand the spread of a potentially deadly canine parasite, researchers at the University of Exeter put LEDs and glow-in-the-dark paint on 450 garden snails and proceeded to film them over the course of 72 hours.
The result is kind of gorgeous and mesmerizing, as tiny points of colored light meander in time lapse through the snails' natural habitat.
Besides the trippy display of gastropod activity, the researchers also learned interesting things: Like the fact that snails can cover as much as 82 feet in a day, and some snails save energy while traveling by using the slime trails left by others.
The researchers, led by Dr Dave Hodgson, Associate Professor of Ecology at the University of Exeter found that snails will travel distances of up to 25 metres in a 24-hour period, and seek out areas of shelter, such as long grass, trees or objects, including dogs' toys, left in the garden overnight. The four researchers from Exeter University also discovered that snails move in convoys, piggy-backing on the slime of other snails to conserve energy. It is thought that a snail could use up to 30 per cent of its energy in slime production alone.
The study was commissioned by the Be Lungworm Aware campaign as a resource for dog owners, whose pets are at risk from a potentially fatal parasite spread by slugs and snails, the lungworm Angiostrongylus vasorum. The parasite is contracted when dogs accidentally swallow even the smallest slugs or snails, which can be found in dog toys, puddles and long grass.

Writing for the New York Times, Heather Murphy has a fascinating story about the unexpected results of a bone marrow transplant. When a patient receives a bone marrow transplant, the patient’s own cells are destroyed and replaced with cells from a donor. Thereafter, the patient is a “chimera,” with two sets of DNA. It’s believed […]
I’m not an engineer, but I can’t stop watching this hypnotic and oddly satisfying video of tying rebar.
The Australian Acoustic Observatory project, described by its creators as a kind of “Google Street View of sound,” is a new acoustic sensor network of hundreds of microphones and digital audio recorders distributed across multiple remote ecosystems on the continent. The solar-powered system will record animal and natural sounds continuously for 5 years. According to […]
The good news: Software like Adobe Premiere Pro, Camtasia and Final Cut Pro has opened up a ton of possibilities for desktop videographers. On the other hand, their use is so widespread that you have to be an expert in them before you can even think about a career in the field. That’s a requirement […]
There are a lot of high-tech drones and RC planes flooding the market lately, and the innovations are coming so fast on each new iteration, most of them forget one crucial thing: Flying these is supposed to be fun. Here’s an alternative that keeps that ethic firmly in mind: The Moskito Smartphone-Controlled Plane. This thing […]
There are few intellectual exercises better than a good game of chess against a capable opponent, which is why a lot of old hands at the gameplay it online. But there’s still nothing like the tactile thrill of moving a knight into checkmate. (Or sweeping the pieces off dramatically when you lose.) That’s why we’re […]
