A fascinating new look at the patents and defense projects in the US Military and its hopefully fusion powered future. (FUSION POWER: Only 20 years away for the last 40 years!! 😉)

Back in 2018, Lockheed Martin filed a patent for something it called a “plasma confinement system” — a device small enough to fit inside the fuselage of an F-16 Fighting Falcon that is capable of managing internal temperatures 10 times hotter than the center of the sun.

This scalable device was designed to play a vital role in containing an approach to power production that some still consider science fiction: nuclear fusion. Now, recent advancements in the field are making fusion power look not just possible, but potentially even feasible. In the coming years, fusion could not only change everything about the way the world fights wars… it could even change the way humanity approaches conflict itself.

“If I’m a farmer in Australia, and I want to know what the drought situation is going to look like over the next 20 to 30 years and decide what sorts of crops I might want to grow or how I might want to change irrigation technologies that I use for my farm, I want to be able to ask questions like that to this digital twin and get answers,” Kashinath said.

FourCastNet, an open-source project, is the first product of the broader Earth-2 initiative available to researchers. And while there’s no specific date for when the team will launch Earth-2 publicly, Kashinath said it will similarly be open for use by the research community.

Hopefully, as tools like Earth-2 emerge, we can better plan for and adapt to our rapidly changing climate.

Technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy was once considered science fiction. Now it is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of California Institute of Technology (Caltech) researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed. They could even send it to places that currently have no access to reliable power.

“This is an extraordinary and unprecedented project,” says Harry Atwater, an SSPP researcher and Otis Booth Leadership Chair of Caltech’s Division of Engineering and Applied Science. “It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world.”

Atwater, who is also the Howard Hughes Professor of Applied Physics and Materials Science, leads the project jointly with two other researchers: Ali Hajimiri, Bren Professor of Electrical Engineering and co-director of SSPP; and Sergio Pellegrino, Joyce and Kent Kresa Professor of Aerospace and Civil Engineering, co-director of SSPP, and a senior research scientist at the Jet Propulsion Laboratory (JPL.

Summary: A genetic form of frontotemporal dementia is associated with abnormal lipid accumulation in the brain fueled by disrupted cell metabolism. The findings could pave the way for new targeted therapies for FTD.

Source: Harvard.

Dementia encompasses a range of neurodegenerative conditions that lead to memory loss and cognitive deficiencies and affect some 55 million people worldwide. Yet despite its prevalence, there are few effective treatments, in part because scientists still don’t understand how exactly dementia arises on a cellular and molecular level.

‘Like conductive Play-Doh’: breakthrough could point way to a new class of materials for electronic devices.

University of Chicago.

Founded in 1,890, the University of Chicago (UChicago, U of C, or Chicago) is a private research university in Chicago, Illinois. Located on a 217-acre campus in Chicago’s Hyde Park neighborhood, near Lake Michigan, the school holds top-ten positions in various national and international rankings. UChicago is also well known for its professional schools: Pritzker School of Medicine, Booth School of Business, Law School, School of Social Service Administration, Harris School of Public Policy Studies, Divinity School and the Graham School of Continuing Liberal and Professional Studies, and Pritzker School of Molecular Engineering.

We all found our coping strategies for riding out the pandemic in 2020. Biomedical engineer Gough Lui likes to tinker with tech—particularly vintage tech—and decided he’d try to recreate what it was like to connect to the Internet via dialup back in the late 1990s. He recorded the entire process in agonizing real time, dotted with occasional commentary.

Those of a certain age (ahem) well remember what it used to be like: even just booting up the computer required patience, particularly in the earlier part of the decade, when one could shower and make coffee in the time it took to boot up one’s computer from a floppy disk. One needed a dedicated phone line for the Internet connection, because otherwise an incoming call could disrupt the connection, forcing one to repeat the whole dialup process.

A team of astrophysicists has revealed an unusual discovery they say appears to challenge our current understanding of gravity based on Newton’s law of universal gravitation, according to a newly published paper.

The controversial claim, published in the Monthly Notices of the Royal Astronomical Society, appears to be consistent with alternative interpretations about one of physics’ most mysterious fundamental interactions.

In their new study, an international team of astrophysicists says that they came upon the discovery while investigating open star clusters. These formations are created as a gas cloud emerges following the birth of thousands of stars within a relatively short time, the remnants of which are ejected as these clusters of stars ignite and begin to expand, which can result in the formation of anywhere from several dozen, to several thousands of new stars.

If conditions on a distant planet allowed life to flourish, would it look anything like life here on Earth? It’s a question that’s seen a Darwinian rise of contradictory theories over the years.

Now, in an interview with the BBC’s Science Focus magazine, Simon Conway Morris, an evolutionary palaeobiologist at the University of Cambridge, says “with reasonable confidence” that human-like evolution has occurred in other parts of the universe.
