Tyvak satellite on SpaceX rideshare mission carries tiny space telescope

Posted by in category: satellites

WASHINGTON — The Tyvak-0130 rideshare payload that flew to orbit May 15 on a SpaceX Falcon 9 carries a miniature space telescope for possible commercial use.

The technology was developed by Tyvak Nano-Satellite Systems and the Lawrence Livermore National Laboratory under a four-year agreement to advance compact telescopes for commercial applications, Tyvak’s CEO Christian “Boris” Becker said in an interview with SpaceNews.

Becker, a retired U.S. Navy rear admiral, was recently named chief executive of Tyvak, a satellite manufacturer in Irvine, California, owned by Terran Orbital.

Understanding dimensionality reduction in machine learning models

Posted by in categories: information science, robotics/AI

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.

Some RNA molecules have unexpected sugar coating

Posted by in category: biotech/medical

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.

Jeff Bezos wants to LIVE FOREVER — Aubrey De Grey: Secret Longevity Investor

Posted by in categories: biotech/medical, life extension, robotics/AI, singularity

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.

Study finds alarming levels of ‘forever chemicals’ in US mothers’ breast milk

Posted by in categories: biotech/medical, chemistry, health

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 moon-sampling Chang’e 5 probe beams home eerie images from deep space

Posted by in categories: habitats, space

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.
