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

Many kinds of cells can sense flow, 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 air force 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.

But there are still plenty of humans involved in preparing orders.

MIT researchers find unintended consequences of an idea to stimulate ocean phytoplankton growth in order to geoengineer a cooler atmosphere.

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.

Using a special liquid, engineers are designing new treatments for spacesuits so that they can better resist puncturing from tiny meteorites and other hazards.

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.

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.
