Attempting to model the universe as precisely as possible is to try to see the one thing that even the strictest atheist agrees is everlasting.
Machine learning algorithms have gained fame for being able to ferret out relevant information from datasets with many features, such as tables with dozens of rows and images with millions of pixels. Thanks to advances in cloud computing, you can often run very large machine learning models without noticing how much computational power works behind the scenes.
But every new feature that you add to your problem adds to its complexity, making it harder to solve it with machine learning algorithms. Data scientists use dimensionality reduction, a set of techniques that remove excessive and irrelevant features from their machine learning models.
Dimensionality reduction slashes the costs of machine learning and sometimes makes it possible to solve complicated problems with simpler models.
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.
“This was probably the biggest scientific shock of my life,” says study author Carolyn Bertozzi, a Howard Hughes Medical Institute Investigator at Stanford University. “Based on the framework by which we understand cell biology, there’s no place where glycan sugars and RNA would physically touch each other.”
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.
Last week, the most prominent figure in the longevity-research community, Aubrey The gray, has announced that one of the biggest event of this community will transpire in around a month. Previous investors were other tech entrepreneur like Peter Thiel or Googles Larry Page.
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.
