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.
A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from […]

There are a lot of different language apps out there because nobody learns anything the same exact way – especially not something as complex as a new language. For some people, the best way is to dive in and start talking, but that’s easier said than done if you’re not around those natives you aspire […]
