Elon Musk, the world’s richest man, is about to get a whole lot richer

Posted by in categories: Elon Musk, space travel

If it was any other plutocrat I’d be disgusted. But Musk is pumping HIS OWN MONEY into SpaceX (and the space sector in general).

After SO MANY YEARS of INEXCUSABLY low levels of funding for human space flight — and for the creation of absolutely critical space infrastructure — I am EXTACTIC at the news!

I don’t always agree with the guy, but I DO deeply believe in what he’s trying to accomplish. I believe in his aspirations for our species. MOST IMPORTANTLY, unlike most of his peers with vaguely similar aims, I believe he can ACTUALLY ACOMPLISH his goals.

Electricity-free radiative system cools buildings and heats water

Posted by in categories: solar power, space, sustainability

Air conditioners and other cooling systems are among our biggest consumers of electricity, so finding ways to passively cool buildings will be important in our increasingly warmer future. Now, researchers at the University at Buffalo have developed a prototype hybrid device that can not only cool buildings drastically without using electricity, it can capture solar energy to heat water.

Created in many forms over the years, radiative cooling systems absorb heat from inside a room or building, and emit it in infrared waves towards the sky. At those wavelengths, the Earth’s atmosphere is “invisible” to the radiation, meaning there’s nothing stopping the heat from venting directly into the cold of outer space.

These devices use panels made of materials that can absorb and emit the heat. The logical way to orient these thermal emitter panels is to have one face pointing towards the sky, like a solar panel, but the team on the new study says that’s not the most efficient method. The panels emit heat from both sides, so in that position some of the heat is being emitted back towards the ground.

Researchers gather numerical evidence of quantum chaos in the Sachdev-Ye-Kitaev model

Posted by in categories: cosmology, particle physics, quantum physics

Over the past few years, many physicists worldwide have conducted research investigating chaos in quantum systems composed of strongly interacting particles, also known as many-body chaos. The study of many-body chaos has broadened the current understanding of quantum thermalization (i.e., the process through which quantum particles reach thermal equilibrium by interacting with one another) and revealed surprising connections between microscopic physics and the dynamics of black holes.

Autonomous ships powered by Mitsui E&S tech can dock at ports

Posted by in category: robotics/AI

Platform addressing labor shortage to be released next fiscal year.


TOKYO — Japanese shipbuilder Mitsui E&S Holdings will soon start selling a navigation system that plans routes and allows vessels to dock automatically.

This is part of the company’s push to use state-of-the-art technology to seize on demand for products that address a labor shortage in the shipping industry.

CDC: people who have received two Covid-19 vaccine doses can skip quarantine

Posted by in categories: biotech/medical, health

People who have received the full course of Covid-19 vaccines can skip the standard 14-day quarantine after exposure to someone with the infection as long as they remain asymptomatic, US public health officials advised.

Biotech entrepreneur George Church launches gene therapy startup to design safer viral vectors

Posted by in categories: biotech/medical, genetics

The adeno-associated viruses often used as vectors to deliver gene therapy can trigger unwanted and sometimes dangerous immune responses. Now, a Harvard University team led by renowned geneticist George Church, Ph.D., has developed a way to “cloak” AAVs from immune surveillance. They’ve spun off Ally Therapeutics to develop it.

NASA decides to launch Europa Clipper on commercial rocket in 2024

Posted by in categories: government, space

Like.


NASA has decided to launch the multibillion-dollar Europa Clipper mission on a commercial heavy-lift rocket in October 2024, and not on the government-owned Space Launch System, officials said Wednesday.

The decision ends a prolonged dilemma for NASA, which until last year was legally required to launch the Europa Clipper mission on the more expensive Space Launch System. The language passed in previous NASA appropriations bills directed NASA to launch the probe on the SLS rocket, but Congress relented in the fiscal year 2021 spending bill passed in December.
