"Scientists Create Tiny Living Robots From Human Cells", he says CNN. Mini-robots "can move around in a lab dish and may one day help heal wounds or damaged tissue, according to a new study."
The lead author of studying he tells CNN, "We don't realize all the abilities that our body's cells have."
A team at Tufts University and the Institute Wyss of Harvard University they called these creations anthropots.
The research builds on previous work by some of the same scientists, who built the first living robots, or xenobots, from stem cells derived from embryos of the African frog (Xenopus laevis)…
The scientists used adult human cells from the trachea, from anonymous donors of different ages and sexes. The cells of the trachea are covered with "hairy" projections called cilia that wave back and forth. They usually help cells in the trachea push out tiny particles that find their way into the air passages of the lungs.
Previous studies have also shown that cells can form organelles – clumps of cells widely used for research. Study co-author Gizem Gumuskaya experimented with the chemical composition of tracheal cell growth conditions and found a way to encourage the cilia to face outwards in the organelles. So he managed to make the organoids mobile after a few days, with the eyelashes acting more or less like paddles…
"In our method, each anthrobot grows from a single cell." This self-assembly makes them unique. Biological robots have been built by other scientists, but they were made by hand by making a mold and adding "seeds" of cells to live on it, study author Michael Levin said. They survived up to 60 days in laboratory conditions.
The experiments described in this latest study are at an early stage, but the goal is to learn whether the anthrobots could have medical applications, Levin and Gumuskaya said.
To see if such applications could work, the researchers tested whether the anthrobots were able to move over human neurons grown in a lab dish that had been "scratched" to mimic tissue damage.
They were surprised to see the anthrobots encourage growth in the damaged area of neurons, although the researchers do not yet understand the healing mechanism.
“This means that although your printer icon and name may look different, the actual operation of the printer remains the same.”
Locally! In the last week I have been scratching my head with another company's printer which LOCALLY works fine but on remote desktop with vpn the forwarding goes crazy! It sends the prints normally to the queue but shows the printer offline! You close the remote and the vpn and the printer starts and prints everything! Also, there was never an hp printer installed on this particular pc, while up until a week ago everything was working normally! Well done microsoft and hp!🥳 (Why hasn't someone made a spitting emoji?)
