A check valve without mechanical parts.
The eccentric inventor is known for dabbling with electricity, but his Tesla valve is impressing scientists anew.
A literature search revealed that one of the Siglec molecules had been previously linked to the autoimmune disease lupus. Finding connections between these different kinds of molecules starts to fill in a new and emerging picture of biology, Bertozzi says. That picture may look something like this: RNA hangs out on the cell surface, decorated with sugars. These sugars stick to Siglec proteins that help the immune system distinguish friend from foe.
In a surprise find, scientists have discovered sugar-coated RNA molecules decorating the surface of cells.
These so-called ‘glycoRNAs’ poke out from mammalian cells’ outer membrane, where they can interact with other molecules. This discovery, reported May 17, 2021, in the journal Cell, upends the current understanding of how the cell handles RNAs and glycans.

Interesting as I recall Aubrey lamenting that he had met Bezos several times over the years but never got a dime from him. Also I wonder where he would put the cash. Just donor all h by is SENS? Pick a company like Age-x?
Jeff Bezos is said to get into the Longevity Industry next month according to Aubrey De Grey. Having a billionaire invest into finding a cure for aging is both amazing and worrisome.
The field of longevity research was long underfunded but recently, with more and more results coming in, investors like Jeff Bezos are getting more and more interested in the field.

As climate change fuels more intense storms, Deltec and other companies build hurricane-proof homes.
Material formed in the wake of the first atomic bomb test contains a strange material that is ordered but that is not a standard crystal.
They are linked to cancer, birth defects, liver disease, thyroid disease, plummeting sperm counts and a range of other serious health problems.
The peer-reviewed study, published on Thursday in the Environmental Science and Technology journal, found PFAS at levels in milk ranging from 50 parts per trillion (ppt) to more than 1850ppt.
Toxic chemicals known as PFAS found in all 50 samples tested at levels nearly 2000 times what is considered safe in drinking water.

China’s Chang’e 5 spacecraft completed a historic delivery of moon rocks to Earth late last year, but the mission is still continuing with experiments in deep space, with a visit to Sun-Earth Lagrange point 1.
3D-printed parts can make rocket engines lighter, less expensive and more efficient.
At Marshall, we’re working with our industry partners to test the latest advances in additive manufacturing technologies:
NASA is partnering with Aerojet Rocketdyne to advance 3D printing technologies, known as metal additive manufacturing, and its capabilities for liquid rocket engines in landers and on-orbit stages/spacecraft.

Warning that the homeland is facing threats that have evolved significantly and become increasingly complex and volatile in 2021, the Department of Homeland Security issued a new National Terrorism Advisory System (NTAS) Bulletin.
The Duke team tested the nanoparticle vaccine by injecting it into macaque monkeys, finding that it provides total protection against SARS-CoV-2, the coronavirus that causes COVID-19. Additionally, the vaccine created antibodies against SARS, bat coronaviruses and the more contagious variants of the virus that causes COVID-19.
May 17—Duke University researchers are developing a vaccine that could provide protection against multiple kinds of coronaviruses, according to a study published last week in Nature, a leading scientific journal. The vaccine, which was developed at Duke’s Human Vaccine Institute, uses nanoparticles to show the immune system 24 copies of a specific part of the virus’ spike protein that attaches to human cells. An additional substance promotes the creation of antibodies that attack that part of the virus.
