Saturday Sciencey Stuff

While reading my normal stuff I come across other fields of interests other than foreign policy…and since my weekends is for FYI my readers to garner more information and knowledge…..

First, the new thing is the invention of “living concrete”…..

Scientists at the University of Colorado, Boulder have created what The New York Times calls a “living concrete,” teeming with photosynthetic bacteria, that can grow itself and regenerate itself — much like a living organism.

The concrete is a mixture of gelatin, sand, and cyanobacteria that cools similarly to Jell-O, the Times reports. The resulting structure was able to regenerate itself three times after researchers cut it apart, suggesting a potential breakthrough in the nascent field of self-assembling materials.

“I Like to be

Under the sea

with the fishes……”

We humans have a limited time in which we can stay under the water…..then came SCUBA and re-breathers……and now we have another invention…..

exolung, an underwater breathing device has been designed to give divers an ‘unlimited’ air supply. it translates the diver’s swimming motions into air movement, keeping breathing air flowing as long as the diver keeps swimming.

exolung is a surface-supplied diving system, which means it uses a buoy that floats on the surface of the water to provide the diver with air. doubling as a safety restraint, a hose measuring 39 feet (12 meters) connects the buoy with the water bell worn on the front of the torso.

inside the bell’s hardshell body, there is a collapsible water bladder attached to leg straps that secure around the diver’s feet. by extending the legs, fresh air is drawn down from the surface and water is displaced from the air bell. when the diver retracts their legs, water pressure puts air inside the bell under ambient water pressure, which can then be inhaled.

Speaking of breathing…..scientist have found a way to make oxygen out of moon dust….

European Space Agency (ESA) scientists say they’ve found a way to produce oxygen from lunar dust. Samples of real lunar dust have been found to be 40 to 45 percent oxygen by weight, according to the ESA.

The team just opened a “prototype oxygen plant” inside a European Space Research and Technology Center lab in the Netherlands.

“Being able to acquire oxygen from resources found on the Moon would obviously be hugely useful for future lunar settlers, both for breathing and in the local production of rocket fuel,” said Beth Lomax of the University of Glasgow in a statement.

Finally, every heard of nano bots?

Well you soon will……

A team of researchers have built what they claim to be the first living robots. The “xenobots,” they say, can move, pick up objects, and even heal themselves after being cut.

The team is hoping the biological machines could one day be used to clean up microplastics in the ocean or even deliver drugs inside the human body, The Guardian reports.

To build the robots, the team used living cells from frog embryos and assembled them into primitive beings.

“These are novel living machines,” research co-lead Joshua Bongard, robotics expert at the University of Vermont, said in a statement. “They’re neither a traditional robot nor a known species of animal. It’s a new class of artifact: a living, programmable organism.”

The millimeter-length robots were designed by a supercomputer running an “evolutionary algorithm” that tested thousands of 3D designs for rudimentary life forms inside a simulation. The scientists then built a handful of the designs, which were able to propel themselves forward or fulfill a basic task inside the simulation using tweezers and cauterizing tools.
