Melbourne startup launches 'biological computer' made of human brain cells

In 2022, a Melbourne start-up announced they’d taught neurons in a dish to play Pong. Now, they’re selling a 'biological computer' made of thousands of human neurons.

Engineers have developed a new type of rotary detonation engine that if it scales up to production will impact mostly military but eventually civilian payloads.

Chinese scientists have successfully developed and tested the world’s first Oblique Detonation Engine (ODE), a hypersonic propulsion system that could allow aircraft to reach speeds of up to 20,000 km/h.

This advancement, published in China's Journal of Experiments in Fluid Mechanics, has the potential to revolutionize air travel and space exploration.

Welcome to The Brave New World Order of Scientific Research.

I suppose this means that any organization that receives any funds/investment from the current US Government will need to fulfill similar requirements to ensure they faithfully follow the edicts of the Trump administration.

Of course the above criteria are also directed to US research. I imagine similar directives have gone to every other country which shares research programs with the US. Europe, Asia, Canada, Timbuktu...

The USA has the right to stop funding research in different areas based on ideology or fear of it being stolen by the Chinese (who are quite effective in Australia doing this).

I think most of it is a box ticking exercise. Just go along with it to keep the research going. If you did have a transgender scientist which is exceedingly rare, then work it out for that case.

Interesting take. But I don't buy it. Fact is the people sending the demand statements will just word check any applications and refuse to support anything with the wrong word in it. They don't even bother reading the context.

The transgender scientist ? Do you believe they are asking about the gender of the scientists on the research team and demanding they only be provable Male and Female ? I thought they were just nixing any research that might investigate any mention of these issues .

Didn't say they were being smart.

Scientists have achieved a major milestone in energy storage after developing a nuclear battery that can convert atomic waste into electricity.

A team in the US has already tested the next-generation battery with a prototype device capable of harvesting enough nuclear radiation to power microchips.

Nuclear batteries have been hailed for their potential to generate electricity for decades without the need for charging or maintenance.

The breakthrough battery, built by researchers at Ohio State University, works by taking ambient gamma radiation from spent nuclear fuel and converting it to light via scintillator crystals. This light is then converted into electricity through solar cells.

“We’re harvesting something considered as waste and by nature, trying to turn it into treasure,” said Raymond Cao, a professor in mechanical and aerospace engineering at Ohio State University, who led the research.

The battery does not incorporate radioactive materials, meaning it is safe to touch, however it is not being developed for public use. Instead, the researchers said they envisioned the batteries being used on nuclear systems for space and deep sea exploration.

Now that would be something if it can be made to work at scale.
Perhaps they could use one to charge the elcetric fence around the nuclear waste dumps.

This discovery has turned science on its head. It turns out that a huge source of natural oxygen production (which we normally associate with photosynthesis and plants ) --- is

Oxygen discovery defies knowledge of the deep ocean​

Until this discovery, it was believed that oxygen could not be produced without sunlight

Scientists have discovered “dark oxygen” being produced in the deep ocean, apparently by lumps of metal on the seafloor.
About half the oxygen we breathe comes from the ocean. But, before this discovery, it was understood that it was made by marine plants photosynthesising - something that requires sunlight.

Here, at depths of 5km, where no sunlight can penetrate, the oxygen appears to be produced by naturally occurring metallic “nodules” which split seawater - H2O - into hydrogen and oxygen.
Several mining companies have plans to collect these nodules, which marine scientists fear could disrupt the newly discovered process - and damage any marine life that depends on the oxygen they make.

“I first saw this in 2013 - an enormous amount of oxygen being produced at the seafloor in complete darkness,” explains lead researcher Prof Andrew Sweetman from the Scottish Association for Marine Science. “I just ignored it, because I’d been taught - you only get oxygen through photosynthesis.

“Eventually, I realised that for years I’d been ignoring this potentially huge discovery,” he told BBC News.
He and his colleagues carried out their research in an area of the deep sea between Hawaii and Mexico - part of a vast swathe of seafloor that is covered with these metal nodules. The nodules form when dissolved metals in seawater collect on fragments of shell - or other debris. It's a process that takes millions of years.

The discovery that lumps of metal on the seafloor produce oxygen raises questions over plans to mine the deep ocean.
