South Africa’s space participation dates back to the 1960s when the National Aeronautics and Space Administration (NASA) first established its Deep Space Network Station, popularly known as DSS-51, in Hartebeesthoek. The station was established to assist NASA’s interplanetary missions. The facility was then operated by the South African Council for Scientific and Industrial Research (CSIR)… […].
In the early days of the pandemic, with commercial COVID tests in short supply, Rockefeller’s Robert B. Darnell developed an in-house assay to identify positive cases within the Rockefeller community. It turned out to be easier and safer to administer than the tests available at the time, and it has been used tens of thousands of times over the past nine months to identify and isolate infected individuals working on the university’s campus.
Now, a new study in PLoS confirms that Darnell’s test performs as well, if not better, than FDA-authorized nasal and oral swab tests. In a direct head-to-head comparison of 162 individuals who received both Rockefeller’s “DRUL” saliva test and a conventional swab test, DRUL caught all of the cases that the swabs identified as positive—plus four positive cases that the swabs missed entirely.
“This research confirms that the test we developed is sensitive and safe,” says Darnell, the Robert and Harriet Heilbrunn professor and head of the Laboratory of Molecular Neuro-Oncology. “It is inexpensive, has provided excellent surveillance within the Rockefeller community, and has the potential to improve safety in communities as the pandemic drags on.”
Schell Games today announced that Lost Recipes, its upcoming historical cooking sim, is set to release January 27th on the Quest platform, bringing with it the chance to cook ancient recipes in period accurate kitchens from around the world.

That’s the future that designers of E-textiles, or smart textiles, want to build.
Fashion trial and error: Smart textiles embed flexible electronics into clothing to give them similar tracking and monitoring capabilities as smartwatches. Today’s market, however, doesn’t have the same kind of demand as it has for the devices we wear on our wrists.
Many of these systems are kept out of equilibrium because individual constituents have their own power source — ATP for cells, gas for cars. But all these extra energy sources and mismatched reactions make for a complex dynamical system beyond the reach of statistical mechanics. How can we analyze phases in such ever-changing systems?
Vitelli and his colleagues see an answer in mathematical objects called exceptional points. Generally, an exceptional point in a system is a singularity, a spot where two or more characteristic properties become indistinguishable and mathematically collapse into one. At an exceptional point, the mathematical behavior of a system differs dramatically from its behavior at nearby points, and exceptional points often describe curious phenomena in systems — like lasers — in which energy is gained and lost continuously.
Now the team has found that these exceptional points also control phase transitions in nonreciprocal systems. Exceptional points aren’t new; physicists and mathematicians have studied them for decades in a variety of settings. But they’ve never been associated so generally with this type of phase transition. “That’s what no one has thought about before, using these in the context of nonequilibrium systems,” said the physicist Cynthia Reichhardt of Los Alamos National Laboratory in New Mexico. “So you can bring all the machinery that we already have about exceptional points to study these systems.”
The uncertainty principle, first introduced by Werner Heisenberg in the late 1920’s, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can also behave like waves. As a result, particles cannot have a well-defined position and momentum simultaneously. For instance, measuring the momentum of a particle leads to a disturbance of position, and therefore the position cannot be precisely defined.

Defense Ministry expects to have a bolstered intercept system by late 2020s.
TOKYO — The Japanese Defense Ministry will develop a means to intercept hostile missiles using magnetically powered projectiles, sources told Nikkei Asia, as the nation scurries to respond to the hypersonic weapons being developed by China, North Korea and Russia.
Just seven months after it announced a milestone record for plasma fusion, the Chinese Academy of Sciences has absolutely smashed it.
Their ‘artificial Sun’ tokomak reactor is has maintained a roiling loop of plasma superheated to 120 million degrees Celsius (216 million degrees Fahrenheit) for a gobsmacking 1,056 seconds, the Institute of Plasma Physics reports.
This also beats the previous record for plasma confinement of 390 seconds, set by the Tore Supra tokamak in France in 2003.
