An all-Princeton research team has identified bacteria that can detect the speed of flowing fluids.

Many kinds of cells can sense , just as our skin cells can feel the difference between a gentle breeze and a strong wind. But we depend on feeling the force involved, the push-back from the air against us. Without that push, we can’t distinguish speed; when the windows are closed, our skin can’t feel any difference in whether we are sitting in an office, a speeding car or a cruising airplane. But now, a team of Princeton researchers has now discovered that some bacteria can in fact detect the speed of flow regardless of the force. Their paper appears in the online journal Nature Microbiology.

“We have engineered bacteria to be speedometers,” said Zemer Gitai, Princeton’s Edwin Grant Conklin Professor of Biology and the senior author on the paper. “There’s an application here: We can actually use these bacteria as flow sensors. If you wanted to know the speed of something in real time, we can tell you.”

To clean up the aviation industry, NASA-funded scientists are working to develop an all-electric aircraft powered by cryogenically-liquified hydrogen fuel.

The University of Illinois scientists behind the project nailed down $6 million over three years from NASA to develop the tech, according to a university-published press release — tech that could, if the project pans out, revolutionize the aviation industry.

U.Scientists are working on next-generation combat wear for soldiers inspired by the nano suit worn in the Iron Man films — and say it could be just two years away.

The Tactical Assault Light Operator Suit (Talos) would effectively give its wearer superpowers, such as the ability to see in the dark, super-human strength and a way of deflecting bullets.

Robot enthusiasts were sending up cheers this month to the team advancing Atlas into an even more human-like walker through obstacles including a bunch of cinder blocks and a balance beam. They have turned Atlas into the very credible hulk, who wins the spotlight with its display of walking, which was recorded May 1.

The video is “IHMC Atlas Autonomous Path Planning Across Narrow Terrain.” Don’t miss the key word “narrow.” This is why the walk is being eyed as a big deal.

Narrow terrain is difficult due to the need to do tricky cross-over steps, tricky, in that there is limited range of motion in the hip joint, said the video notes. There was “a small polygon of support when one foot is directly in front of the other.”

Computer scientists the University of Melbourne in Australia and the University of Toronto in Canada have developed an algorithm that is capable of writing poetry following the rules of rhyme and metre.

With the use of poetries rules and taking the metre into account, this AI algorithm creates weaves of words and grouped them together to produce meaningful sentences.

This AI is trained extensively on the rules it needed to follow to craft an acceptable poem and the dataset researcher used to train the AI has over 2,600 real sonnets.
