They are undifferentiated cells capable of being anything. You might know them as stem cells and now a robot can take them up your nose into your brain. "Researchers have developed a stem cell-based microrobot called "cellbot" capable of delivering stem cells to the brain via intranasal passage using a minimally invasive method. The cellbot has the potential to become a key player in the treatment of neurological disorders such as brain cancer, Parkinson's disease and Alzheimer's disease."

Would you eat meat grown in a lab to save the world? The $10 million award will enable the creation of the first-ever U.S. government-funded cultivated protein research center of excellence and represents U.S. Department of Agriculture (USDA)'s first investment in cultivated meat to date. USDA awarded the grant as a part of a $146 million investment in sustainable agricultural research projects announced by USDA Secretary Tom Vilsack on October 6.

It reversed age-related inflammation in the body and the brains of older mice, and changed the chemistry of their brain's hippocampus - the region involved in learning and memory - to resemble that of younger mice. The transplant also led to improvements in the older mice's memory, learning and anxiety levels, all of which are affected negatively with age.

Is it time to pick up some PSYK, PSY and PSIL ETFs? "Given the strong results, Compass Pathways plans to move ahead with a late-stage clinical trial of psilocybin, likely using the 25-milligram dose, but that detail still needs to be discussed with regulators. The recent trial was a so-called Phase 2B trial, which was intended to figure out the appropriate dose; the next trial, a Phase 3, will test that chosen dose in a larger group." Where do we sign up?

Wow, check out the picture of the Meat 3-D printer on this article. "The "meat" is 3D printed, and the mimicry is extraordinary. The molecules of difference that create the flavour of beef, as distinct from that of lamb, are few but extremely powerful. This is certainly the closest synthetic approximation yet."
