A Small-Rocket Maker Is Running a Different Kind of Space Race

Walking and running may affect the functional connectivity of brain networks in different ways, according to a new study.
A tiny nanoparticle has been chilled to the max.
Physicists cooled a nanoparticle to the lowest temperature allowed by quantum mechanics. The particle’s motion reached what’s known as the ground state, or lowest possible energy level.
In a typical material, the amount that its atoms jostle around indicates its temperature. But in the case of the nanoparticle, scientists can define an effective temperature based on the motion of the entire nanoparticle, which is made up of about 100 million atoms. That temperature reached twelve-millionths of a kelvin, scientists report January 30 in Science.
Regenerative medicine and furthermore tissue engineering are realities for some time but well hidden from the public by msm somehow.
Dr. Stephen Badylak, Director of the Center for Pre-Clinical Tissue Engineering, McGowan Institute for Regenerative Medicine.
“It regenerates almost anything after almost any injury that doesn’t kill it,” said Parker Flowers, postdoctoral associate in the lab of Craig Crews, the John C. Malone Professor of Molecular, Cellular, and Developmental Biology and professor of chemistry and pharmacology.
If scientists can find the genetic basis for the axolotl’s ability to regenerate, they might be able to find ways to restore damaged tissue in humans. But they have been thwarted in the attempt by another peculiarity of the axolotl — it has the largest genome of any animal yet sequenced, 10 times larger than that of humans.
Now Flowers and colleagues have found an ingenious way to circumvent the animal’s complex genome to identify at least two genes involved in regeneration, they report Jan. 28 in the journal eLife.
Do you think Xenobots is the early stage of nanobots, which could repair our body to achieve longevity escape velocity?
Scientists have created the world’s first living, self-healing robots using stem cells from frogs.

When Mina Jang played the same melodious tune on two different flutes behind a screen, she said the examiners grading her couldn’t tell the difference.
Yet the two instruments were made in dramatically different ways.
One was a handmade version of an original early 18th-century flute crafted in 2001, while the other was made of white plastic and “cloned” using a 3D printer in 2019.
Today’s super-rich are putting record sums into tackling the world’s most pressing problems. But how altruistic is this golden age of charitable giving?
Today’s super-wealthy are richer than ever. And they’re giving away their billions like never before. Philanthropists are putting record sums into tackling the world’s most pressing problems. And unlike the mega-donors of the past today’s philanthropists want to see the results in their lifetimes. But how altruistic is this new golden age of giving? Have these mega-donors become too powerful?
