Submission + - Cats Meow More Than Twice as Much at Men, And We Can Only Guess Why (sciencealert.com) 1
alternative_right writes: "Our results showed that cats vocalized more frequently toward male caregivers, while no other demographic factor had a discernible effect on the frequency or duration of greetings," write the researchers in their published paper.
A total of 22 different behavior types were looked at by the researchers, including yawning (often a sign of cat stress) and food-related behaviors (including heading to their food bowl). The vocalizations were the only behaviors that changed based on the owners' sex.

Randseed writes: With the likes of Google Nest, Ring, and others cooperating with law enforcement, I started to look for affordable wireless IP security cameras that I can put around my house. Unfortunately, it looks like almost every thing now incorporates some kind of cloud-based slop. All I really want is to put up some cameras, hook them up to my LAN, and install something like Zoneminder. What are the most economical, wireless IP security cameras that I can set up with my server?

And I say that that applies to autism to. Social skills is something you need to practise as child, it is not congenital. Some have more talent for this, other less. The latter need to practise. Just like with everything from math to juggle balls.

alternative_right writes: Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date. This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy consumption. The discovery also enhances the prospects for silicon-based quantum devices.

Submission + - Idaho Lab Produces World's First Molten Salt Fuel For Nuclear Reactors (cowboystatedaily.com)
schwit1 writes: The U.S. Department of Energy Office of Nuclear Energy announced this week that researchers at INL have successfully created the first batch of fuel salt.
Fuel salt is a molten salt mixture used as both a carrier for nuclear fuel and coolant in a molten salt reactor, a type of advanced nuclear reactor.
The fuel salt is critical for conducting the world’s first fast-spectrum, salt-fueled reactor test, known as the Molten Chloride Reactor Experiment (MCRE).
The test will help inform the future commercial deployment of a new class of advanced nuclear reactors, something a number of Wyoming-connected companies are proposing to build.
“There is a lot of push for this,” said James King, project lead for the Molten Chloride Experiment at INL. “We need to have a lot of different options so we can move away from less safe power generations methods.
“This is one of those technologies that can move us to better safety.”
The liquid form of the salt fuel means the fuel can’t melt. The technology would also offer another low-carbon alternative to generating power.

President Donald Trump says he's moving to legalize Japan's beloved kei cars — the tiny, boxy, almost toy-like vans, trucks, and coupes that have a cult following overseas. And he wants US automakers to start building them here.
This makes a lot of sense in urban settings, especially when electrified. Hopefully these are restricted from highway system.

The European Union's plan to ban new combustion cars starting in 2035 may be over before it has a chance to go into effect, if Germany's leader has anything to say about it.
2035 target was simply infeasible with current technology. While some promising new developments, like solid state batteries, are being worked on, they are not yet ready for mass production.

If that's true, that violates freedom of contract, and should not be banned. But it doesn't matter because the only thing that the government should regulate in that situation is that important details about the car that is sold should be listed. Fraud is illegal everywhere.

alternative_right writes: According to a 2023 review that brought together data from dozens of studies, distinct differences can be seen between the gut microbiomes of 'speeders' and 'slowpokes'.
Since the human gut microbiome is intrinsically linked to health, this could have implications that have gone unnoticed before now.
In particular, slow transit times and constipation have been linked with metabolic and inflammatory disorders, as well as neurological disorders such as Parkinson's disease.
