"I am Iron Man." Former "MythBusters" co-host Adam Savage just showed off an incredible-looking, 3D-printed titanium Iron Man suit. And yes, it can fly, just like Tony Stark’s fictional model. The jetpack behind the suit comes courtesy of @takeongravity (Gravity Industries), a startup run by UK inventor Richard Browning, and uses five 1,000 horsepower mini jet engines.

"Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don’t just give up." – Stephen Hawking
The Venus fly trap lures its prey with nectar and, when the moment is right, its jaws close. Contrary to popular belief, flying insects make up less than 5% of the plant's diet. - 💀 Fun Fact: Studies have shown these carnivorous plants can even digest small bits of human flesh. - Via @sciencechannel Follow @science.feed for more!
Is this person still alive? (Look, but DON’T touch) - 🐙 Characterized by its blue and black rings which appear when the animal feels threatened, the seemingly harmless mollusk possesses a venomous neurotoxin, known as tetrodotoxin, which it releases through its salivary glands. Technically, all octopuses and cuttlefish are venomous, but the blue-ringed octopus can’t be compared. - ☠️ Tetrodotoxin is 1,000 times more deadly than cyanide and the amount of poisonous liquid the little cephalopod carries can mean certain death for up to 26 people, or leave someone paralyzed for up to 24 hours after initial contact. Worse yet, there is no known antidote. A victim’s best bet is to get respiratory assistance immediately. - 🧠 People who have received a dose of tetrodotoxin can be fully aware of their surroundings, but unable to move, and with no way of signaling for help. - Follow @science.feed for more!
Meet Cryptobranchidae, a family of giant salamanders that can reach up to 1.8 meters in length. - 🔍 Cryptobranchids live exclusively in fast-flowing streams. Lacking gills as adults, the wholly aquatic cryptobranchids breathe primarily through their skin, which hangs loosely about them in folds. They have unusual specializations associated with cutaneous respiration, including the extreme vascularization of these skin folds, which allows water containing oxygen to come into contact with the folds. Cutaneous respiration is further aided by the side-to-side swaying of the body, especially in slower moving water. Cryptobranchids also use their lungs to breathe. - Follow @science.feed for more!
Scientists in China have created a monkey that may be a little bit more like us. They’ve tried to narrow the evolutionary gap, creating several transgenic macaque monkeys with extra copies of a human gene suspected of playing a role in shaping human intelligence. - 🧠 Researches inserted copies of the MCPH1 gene, which is believed to play a role in brain development, and introduced it into monkey embryos through a virus that carried the gene. Six of the 11 monkeys they created died, but the ones who survived did not have bigger brains. They did, however, perform better on short-term memory tasks. The monkey’s brains also developed over a long period of time, much like human brains. Now onto the question of ethics. - Via Antonio Regalado, MIT Technology Review Follow @science.feed for more!
