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.

Scientists say that traces of SARS-CoV-2 genetic material — viral RNA — in the poo we flush down the toilet and into the sewage system might reveal how badly coronavirus has hit a given community. Analyzing sewage could show the true scale of an outbreak, in the absence of available testing, they say.
Even tho they are only updated once a day (at most) I check, check and re-check 91-divoc and the IHME COVID-19 Projections. The linear scale graphs on 91-divoc have given me the best picture of ‘is the curve flattening’ for the regions I watch. Tribalism runs rampant during Trump’s Pandemic and I am naturally more […]
More than 125 of these curious soccer ball-sized glass spheres hang near the floor of the Mediterranean Sea. Even though they’re deep underwater, they’re keeping a constant vigil for neutrinos, particles that may be evidence of dark matter, supernovae, and neutron stars far off in intergalactic space. Eventually, the Cubic Kilometer Neutrino Telescope (KM3NeT) will […]
Yoga studios are closed nationwide. The irony is that between the anxieties of the outside world and those popping up inside your very own home with everyone trapped indoors, there’s probably never been a time where yoga’s calming zen was more vital and needed. Rather than just throwing in the yoga mat and subjecting family […]
The workers aren’t inside their physical business space anymore. So why should business technology still be under that roof either? In fact, more and more businesses have been making this migration for a while now, moving all their digital infrastructure to the world’s two largest cloud services platforms, Amazon Web Services (AWS) and Microsoft’s Azure. […]
Gather round, young and old — and hear tales of bygone days. Back in olden times, citizens would mass at a house of coffee, wherein skilled java alchemists would concoct special blends and apply artisanal wizardry to make each steaming chalice an appointment for the taste buds. Granted, said wizards, once known as baristas, were […]
