NASA just announced several bounties to improve its FUN3D software, which is used to simulate fluid dynamics. The system is used internally at NASA, as well as by companies like Boeing and Lockheed, to develop and optimize new vehicles and engines.

The FUN3D project was started back in the 1980s, and it has been in active development for decades, but NASA’s looking for help to optimize the code. It’s offering $15,000 and $10,000 prizes to the top two contributors of code optimizations, and is also offering another bounty for more general optimization suggestions.

For decades, scientists have tracked hints of a thread-like structure that ties together galaxies across the universe. Theories, computer models, and indirect observations have indicated that there is a cosmic web of dark matter that connects galaxies and constitutes the large-scale structure of the cosmos. But while the filaments that make up this web are massive, dark matter is incredibly difficult to observe.

Now, researchers have produced what they say is the first composite image of a dark matter filament that connects galaxies together.

“This image moves us beyond predictions to something we can see and measure,” said Mike Hudson, a professor of astronomy at the University of Waterloo in Canada, co-author of a new study published in the Monthly Notices of the Royal Astronomical Society.

Physicists at the University of California, Irvine and elsewhere have fabricated new two-dimensional quantum materials with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics.

In three separate studies appearing this month in Nature, Science Advances and Nature Materials, UCI researchers and colleagues from UC Berkeley, Lawrence Berkeley National Laboratory, Princeton University, Fudan University and the University of Maryland explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.

The common threads running through the papers are that the research is conducted at extremely cold temperatures and that the signal carriers in all three studies are not electrons — as with traditional silicon-based technologies — but Dirac or Majorana fermions, particles without mass that move at nearly the speed of light.

Physicists have been testing the properties of new 2D quantum materials that could usurp graphene as the ‘wonder materials’ of the future.

These materials, which can conduct electricity at nearly the speed of light, could replace silicon in the next generation of hyper-speed computers. One could even form the basis of a new “exotic superconductor” that could actually break time-reversal symmetry — or reverse the flow of time.

“Finally, we can take exotic, high-end theories in physics and make something useful,” says one of the researchers, Jing Xia, from the University of California, Irvine.

Researchers have built a primitive microprocessor out of a two-dimensional material similar to graphene, the flexible conductive wonder material that some believe will revolutionize the design and manufacture of batteries, sensors and chips.

With only 115 transistors, their processor isn’t going to top any benchmark rankings, but it’s “a first step towards the development of microprocessors based on 2D semiconductors,” the researchers at Vienna University of Technology said in a paper published in the journal Nature this month.

Tesla founder and chief executive Elon Musk said his latest company Neuralink is working to link the human brain with computers by creating micron-sized devices.

Neuralink is aiming to bring to the market a product that helps with certain severe brain injuries due to stroke and cancer lesion in about four years, Musk said in an interview with the website Wait But Why on Thursday.

“If I were to communicate a concept to you, you would essentially engage in consensual telepathy,” Musk said in the interview. Neuralink will be Musk’s third company along with Tesla and SpaceX.
