Science-tech updates - young blood for old? And much more.


Did we dodge a sci fi scenario of unparalleled potential nastiness? Already around the world, rich old struldbrugs are buying “fresh young blood” from healthy donors in their 20s… and on a very limited scale there’s no reason yet to get upset from a two way beneficial business arrangement. But it was easy to extrapolate that into a nightmare, if the fast rising world mafia-feudal oligarchy really sank their vampire teeth in, taking advantage of vast wealth disparities their cheating created. 

Now possible good news, evading that one (of many) nightmare. “In 2005, the same team demonstrated that connecting the blood of young and old mice (essentially making them conjoined twins) resulted in rejuvenation. Yet the present study showed equal or greater enhancements by solely diluting the blood of the old mice, eliminating the need for young mice entirely.” The Peter Diamandis site concludes: “This discovery shifts our attention away from young blood and towards the importance of age-related harmful proteins in old blood. Rather than focusing on specific protein therapeutics, age reversal is more likely linked to a host of proteins that can be naturally triggered by dilution processes such as this study’s approach.”

Might I add that similar effects may come from blood DONATION  several times a year? It certainly feels that way to me!
(I donated my 94th pint a couple of weeks ago and got a free covid test, along with an apple juice and chexmix.) And yes, this segues into several scenes in Existence. And especially… “The Giving Plague.”  (Free on my website.)

Meanwhile, though few news articles refer to Uplift: “Scientists have grown larger monkey brains by giving marmoset fetuses a gene that's unique to humans.”

Way kewl science experiment! An Inverted tornado ignited inside of a bubble.

How Heisenberg became uncertain: An amusing story about how a young Heisenberg (not the Breaking Bad version) – embarrassed by a barely-passed exam – studied the ultimate limits of microscopes and thereby derived his famous uncertainty principle… 100% correctly, if for some wrong reasons!

A well-produced rap about climate change… is responded by a pretty cool and uber-nerdy rap about carbon-sequestration and “air-mining” — concluding and coolly summarizing the zoom conference I just attended. Uber-nerdy? Super-ooper-dooper-nerdy-cool! Problem solvers. My kind of people.

== More tech news! ==

Hydraloop unveiled a wastewater management solution. About the size of a refrigerator, Hydraloop’s system purifies wastewater and returns it for use in washing, gardening and plumbing.

AWG in the news: An Israeli water-from-air system that taps into atmospheric water using patented heat-exchange technology. 

Pretty important actually: researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.  This could make a huge difference also in the growth of vertical/urban farms.

What appear to be super high energy neutrinos shooting UP to hit a balloon-carried detector above Antarctica have unsettling implications for the Standard Model of Physics.

Bose-Einstein condensates (BEC) are collections of atoms coaxed into sharing a common quantum state. They are very fragile.  BECs in terrestrial labs typically last a handful of milliseconds before dissipating. But in space they feel no gravitational net force and can be suspended much easier. Aboard the ISS the BECs lasted more than a second, offering the team an unprecedented chance to study their properties. Previous studies trying to emulate the effect of weightlessness on BECs used airplanes in free fall, rockets and even apparatus dropped from various heights. But these experiments are… cool.

Analysis of seismic waves reveal “echoes from the boundary between Earth's molten core and the solid mantle layer above it. The echoes revealed more widespread, heterogenous structures—areas of unusually dense, hot rock—at the core-mantle boundary than previously known.” A region very much involved in the plot of my novel EARTH.

Instead of cooling things down near absolute zero, to preserve fragile entanglement, these researchers took the opposite approach, heating atoms to millions of times hotter than a typical quantum experiment – the temperature of a kitchen oven - to see if entanglement could persist in a hot and chaotic environment. “The surprising thing is that these random collisions didn't destroy entanglement." Unlikely to be useful for computation, this may lead to new kinds of sensitive detectors.

If verified, this is actually a pretty big deal! Abstract: “Biological molecules chose one of two structurally chiral systems which are related by reflection in a mirror. It is proposed that this choice was made, causally, by cosmic rays, which are known to play a major role in mutagenesis. It is shown that magnetically polarized cosmic rays that dominate at ground level today can impose a small, but persistent, chiral bias in the rate at which they induce structural changes in simple, chiral monomers that are the building blocks of biopolymers.”

When the squid hunt, they communicate with each other via patterns of light and dark pigment on their skin. Even in the ocean depths, these patterns can be detected because the squids’ bodies glow in the dark, revealing patterns that are backlit like words on an e-reader screen.

More life weirdness. Last time I talked about insects with tooth-gears in their leg joints. Now something I referred to speculatively in EARTH and even earlier in THE UPLIFT WAR…  Cable bacteria grows on a mat on and under the sea floors and what makes it interesting is that they power themselves by electricity and send that electricity over long distances using biological cables that have similar efficiency to that of copper wire. Apparently the bacteria is widespread on sea bottoms around the world and could possibly like fungi form a single organism of unknown size. 

They estimate that a cubic meter of the seafloor mud containing Cable bacteria contains hundreds of thousands of kilometers of bio-electric cables that transmits electricity as efficiently as what we can do today. If it transmits electricity it can also transmit signals. If we extrapolate that out to the size of the Earth’s ocean floors then we’re talking about a potential nervous system component for a living Gaia that doesn’t require the mantle superconductors of EARTH. Though, it could also be “angry” as in Greg Bear’s disturbing book VITALS.
