Here's how the hydra rips its own body open to eat a meal
Hydra opens its mouth over the course of 13 seconds. (UC San Diego) It's hard out there for a hydra. Scientists from the University of California have detailed the process by which the tiny freshwater creature Hydra vulgaris opens its mouth, and it ain't pretty: It has to rip a hole into its own body every time it consumes food. Scientists already knew that the tiny aquatic creature Hydra vulgaris had to split its skin open every time it opened its mouth. Now, using a genetically modifie..>> view originalLittle bird uses a linguistic rule thought to be unique to humans
A study published in Nature Communications suggests that a small bird known the Japanese great tit uses grammatical rules in its calls. Until now, only humans seemed to use syntax this way. When it comes to human language, syntax — the set of rules for arranging words and phrases to impart meaning — is important. People might understand what you meant if you declared “to the store I go must,” but your phrasing wouldn’t seem quite right. And saying “must store go the I to” wouldn’t get you anywh..>> view originalToyota's first wearable aims to improve mobility for the blind

The Samsung Galaxy S7 and S7 Edge are beautifully well-executed smartphones, worthy flagships from one of the world's largest electronics manufacturers. The changes from last year's S6 lines are incremental, but the fixes and upgrades are in all the right places. Those small improvements make for two vastly better phones, which start at $650 (for the S7) and $750 (for the S7 Edge), depending on the carrier. Samsung, like its bête noire Apple, seems to be on a two-year schedule, with major..>> view originalAmazon Is Trying A Whole New Way to Get Into Virtual Reality – Tech Roundup

Scientists have long puzzled over the shade of the planet closest to the Sun. Mercury's surface appears remarkably dark, but why?Thanks to data from NASA's MESSENGER spacecraft that orbited the planet from 2011 to 2015, researchers might have an answer.A new analysis of the data identifies carbon, in the same form as the "lead" in a pencil, as the dark substance on the planet's surface. And this could mean that Mercury's original crust was made of graphite, scientists say in a paper published M..>> view originalOvernight Regulation: FCC to offer Internet subsidies to 40M households
