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.
Researchers successfully taught rats how to drive small cars in the pursuit of Froot Loops cereal. Video below. Psychologist Kelly Lambert and her colleagues at the University of Richmond conducted the experiment to gain insight into animal cognition. Learning to drive also lowered the rats’ stress as measured by hormone levels. From New Scientist: They […]
Russian scientist Denis Rebrikov claims that he’s begun a gene-editing process to eventually enable couples who both carry a specific genetic mutation that causes deafness to birth children who can hear. Rebrikov formerly announced his effort to use the CRISPR tool for gene editing to create babies resistant to HIV. From Nature: In his e-mail […]
Caltech theoretical physicist Sean Carroll, author of Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime, explains the concept of a “dimensions” at five different levels of complexity. Dr. Carroll sure has a big brane.
If you’re just jumping into app development for Apple’s devices, you’ve picked a heady time. The new iOS 13 has a ton of new features: A versatile SwiftUI language, a boosted role for Siri and a more robust Photos app, just to name a few. And if you’re making the transition from iOS 12? Get […]
Most people don’t spare a lot of thought on the potting for their plants. Perhaps something with a color that matches the walls, but that’s as far as it goes. After all, the plants don’t care what they’re wearing. Do they? Actually, they might. As eye-catching as the AIRSAI Floating Bonsai Plant Pot is, its […]
With the gains real estate has made over stocks in the past 25 years, it’s easy to see why the rich constantly use it to expand their wealth. What’s slightly less obvious is why only the rich seem to ever break into real estate investment. There are a lot of reasons, but a couple of […]
