New research shows that bees can recognize flowers by the plants' tiny electric field that differs between species. The electric field bends the tiny hairs on a bee's body, firing neurons located at the base of the hair. From the journal Science:
Such fields—which form from the imbalance of charge between the ground and the atmosphere—are unique to each species, based on the plant’s distance from the ground and shape. Flowers use them as an additional way to advertise themselves to pollinators...
Electric fields can only be sensed from a distance of 10 cm or so, so they’re not very useful for large animals like ourselves. But for small insects, this distance represents several body lengths, a relatively long distance.
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
This is so amazing. Watch what happens when a blacksmithing anvil is lowered into a large vat of pure liquid mercury. Update: One of our readers posted the link to the original video in the comments. I have replaced the animated GIF. Thanks, Crispy75. [H/t Alberto Gaitán via Bryce Lynch] Image: Screengrab from GIF
If you remember your Norse mythology (or just watched Marvel’s Thor movies), you’re probably familiar with Heimdal, the god whose ever-watchful eye was entrusted with protecting the home of the gods in Asgard. Back on Earth, Heimdal Thor is also the name of a security package from Heimdal Security, that’s actually dedicated to much the […]
