Antidepressant Significantly Reduces Covid-19 Hospitalization

Posted by in category: biotech/medical

Covid-19 patients who were given the low-cost antidepressant fluvoxamine were significantly less likely to require hospitalization compared with those who weren’t, according to a new study.

Elon Musk slams billionaire tax: ‘Eventually, they run out of other people’s money and then they come for you’

Posted by in categories: Elon Musk, neuroscience

No. Eventually billionaires will run out of OUR money, NOT the other way around. I love the things and companies he’s created. I love the industries he’s revolutionized and the massive Kickstart he has given to our entire species and it’s extrasolar future. He is INARGUABLY a brilliant man. But he’s also a shitty human being. He’s like so many other brilliant people that enjoy public life and the sound of his own voice who can all too often forget that they are NOT experts in EVERYTHING ELSE just because experts on something else. Musk is just another example of that kind of ego overspill. It’s not the first time he’s done it, and it will NOT be the last or worst occurrence of… Let’s call it the “Big brain on Brad golden suitcase of indeterminate origin syndrome.”

A New Family of Electromagnetic Pulses: Skyrmions Can Fly!

Posted by in categories: information science, nanotechnology, particle physics

Topology in optics and photonics has been a hot topic since 1,890 where singularities in electromagnetic fields have been considered. The recent award of the Nobel prize for topology developments in condensed matter physics has led to renewed surge in topology in optics with most recent developments in implementing condensed matter particle-like topological structures in photonics. Recently, topological photonics, especially the topological electromagnetic pulses, hold promise for nontrivial wave-matter interactions and provide additional degrees of freedom for information and energy transfer. However, to date the topology of ultrafast transient electromagnetic pulses had been largely unexplored.

In their paper published in the journal Nature Communications, physicists in the UK and Singapore report a new family of electromagnetic pulses, the exact solutions of Maxwell’s equation with toroidal topology, in which topological complexity can be continuously controlled, namely supertoroidal topology. The electromagnetic fields in such supertoroidal pulses have skyrmionic structures as they propagate in free space with the speed of light.

Skyrmions, sophisticated topological particles originally proposed as a unified model of the nucleon by Tony Skyrme in 1,962 behave like nanoscale magnetic vortices with spectacular textures. They have been widely studied in many condensed matter systems, including chiral magnets and liquid crystals, as nontrivial excitations showing great importance for information storing and transferring. If skyrmions can fly, open up infinite possibilities for the next generation of informatics revolution.

Something Really Wants Our Attention: One Cosmic Object Emitted 1,652 Fast Radio Bursts in 47 Days

Posted by in category: space

The energetic phenomena known as Fast Radio Bursts (FRBs) are one of the greatest cosmic mysteries today. These mysterious flashes of light are visible in the radio wave part of the spectrum and usually last only a few milliseconds before fading away forever. Since the first FRB was observed in 2,007 astronomers have looked forward to the day when instruments of sufficient sensitivity would be able to detect them regularly.

That day has arrived with the completion of the 500-Meter FAST Radio Telescope (aka. Tianyan, “Eye of Heaven”). Since it commenced operations, this observatory has vastly expanded the number of detected FRBs. In fact, according to research led by the National Astronomical Observatories of the Chinese Academy of Sciences (NAO/CAS), the observatory detected a total of 1,652 independent bursts from a single source in 47 days.

Taiwan Has Made A Battery-Powered Exoskeleton To Give Super Strength To Its Soldiers

Posted by in categories: cyborgs, military

Taiwan has made a battery-powered exoskeleton suit that will allow its soldiers to run faster and carry heavy objects.

This is the first-generation suit made by the National Chung-Shan Institute of Science and Technology, according to The South China Morning Post. The suit is a part of a four-year project called the “Taiwan Ironman program.” It has a budget of $5.74 million and the goal of providing Taiwan’s soldiers with a lower-body exoskeleton to increase their strength and endurance.

“To reduce fatigue of soldiers in carrying heavy facilities… we started developing the powered suit for the military in 2020,” Jen Kuo-Kuang, head developer of the project, said in comments at a news conference obtained by the SCMP.

Child psychiatric disorders, such as oppositional defiant disorder and attention-deficit/hyperactivity disorder (ADHD), can feature outbursts of anger and physical aggression. A better understanding of what drives these symptoms could help inform treatment strategies. Yale researchers have now used a machine learning-based approach to uncover disruptions of brain connectivity in children displaying aggression.

FlexSail: Solar Sails and Tech Revolutions — Kent Nebergall — 2021 Mars Society Virtual Convention

Posted by in categories: bioengineering, economics, environmental, genetics, government, information science, robotics/AI, solar power, space, sustainability

Track code: TD-3

Abstract:
Solar Sails are at the same stage of engineering development as electric motors were in the 1830’s. Each attribute of solar flux has been examined in isolation, such as photon, proton, plasma, and electrodynamic systems. This talk recommends designing a simple baseline system that converges multiple propulsion methods into optimized systems, as is currently done with electric motors. Many convergences can come from this solution space. Once a baseline design is created, AI genetic algorithms can “flight test” and refine the designs in simulation to adjust proportions and geometry. Once a base design is refined, a second AI evolution pass would design fleet systems that flock like birds to optimize performance. These could fly as a protective shield around Mars crewed fleets, provide space based solar power, deploy rapid reaction probes for interstellar comets, and be used in NEO asteroid mining. In the long term, fleets of solar energy management vehicles can provide orbital Carrigan event protection and Martian solar wind protection for terraforming. This talk is also a case study in how technology revolutions happen, and how to accelerate the creation and democratization of technical solutions.

China’s cell-based meat revolution on the cusp of becoming the next big tech boom

Posted by in categories: climatology, government, solar power, sustainability

26 Oct 2021 — Public Chinese government records reviewed by the Good Food Institute (GFI) APAC indicate that significant funds are being allocated to help the nascent alternative protein sector optimize and scale up – as was previously done for the nation’s development of solar panels, lithium-ion batteries and electric vehicles.

While Chinese funding for alternative protein remains a tiny proportion of what the nation is capable of, these moves by various government entities demonstrate the scope of interest among local officials, which could potentially position China at the forefront of the next big food tech boom.

“There is no pathway to achieve the climate goals set out in the Paris Agreement without changing how we produce protein, but encouraging new evidence suggests that Chinese leaders understand the massive benefits of making meat from plants and growing it directly from cells,” stresses the GFI.
