Shapeshifting wheel
Posted in military
The military is developing a shapeshifting wheel that is capable of transforming in just 2 seconds.
Maybe interesting for this group too.

The danger of artificial intelligence isn’t that it’s going to rebel against us, but that it’s going to do exactly what we ask it to do, says AI researcher Janelle Shane. Sharing the weird, sometimes alarming antics of AI algorithms as they try to solve human problems — like creating new ice cream flavors or recognizing cars on the road — Shane shows why AI doesn’t yet measure up to real brains.

An international team of scientists has created the most detailed large-scale model of the universe to date, a simulation they call TNG50.
Researchers working on ways to accelerate the body’s healing and regeneration. But what are the limits of that science and what does its future look like?
Heliogen is a startup that wants to “replace fuels with sunlight.” And the Bill Gates-backed solar startup, which has flown under the radar until today, has made a major green-energy breakthrough for heavy industry. Heliogen “has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.”
In movies and books, fictional astronauts enter ‘suspended animation’ to cross the vastness of space. Recently ESA investigated how real-life crew hibernation would impact a space mission to Mars.
Vulnerabilities in the Google Camera app left hackers able to take photos, and silently record audio and video, even when the phone was locked.

An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.
The team discovered ribose and other bio-essential sugars including arabinose and xylose in two different meteorites that are rich in carbon, NWA 801 (type CR2) and Murchison (type CM2). Ribose is a crucial component of RNA (ribonucleic acid). In much of modern life, RNA serves as a messenger molecule, copying genetic instructions from the DNA molecule (deoxyribonucleic acid) and delivering them to molecular factories within the cell called ribosomes that read the RNA to build specific proteins needed to carry out life processes.
