Solar power just hit a new milestone. Chinese researchers broke the 10% efficiency barrier for selenium solar cells for the first time, reaching 10.3%.
What makes this exciting: selenium cells have wider bandgaps and high efficiency potential. The team used optimized contacts, light-driven crystallization, and special annealing techniques.
The result? Stable devices that lost minimal efficiency after 1,000 hours of testing.

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes,

Scientists are realizing the defining qualities that make up each cell actually lie in a cousin of DNA called RNA.

The fascist who killed Heather Heyer at Unite the Right helped turn the tides against the last Trump administration. He said there were "very fine people on both sides." The resistance grew, antifa doxxing fascists started getting those fash fired.
But some of those fash didn't stop. They kept organizing their terror cells. The fash who killed Heyer was with a group called Vanguard America. Patriot Front is a Nazi group that split off from Vanguard America. They started terrorizing people by loading up in box trucks and piling out for spontaneous marches.
That box truck tactic probably sounds familiar. Patriot Front basically disappeared at the same time that ICE started recruiting hard.
Let me make it more clear. The very same Nazis from UTR who killed Heather Heyer, who Trump called "very fine people," are now employees of DHS. They've been carrying out the ethnic cleansing they always dreamed of, and they're being paid by the government, *with your tax dollars*, to do it. And now, just like in Charlottesville, they've murdered an unarmed protestor.
This feels similar because it is. These are the same people killing daughters and mothers. Killing unarmed protestors, out of rage not fear, then lying and claiming self defense. This is the same tactic it's always been. This is the same thing they've always done.
It seems like we may have reached the Heather Heyer point of this administration early with Renee Good. Now would be a good time for everyone to get into the streets and stay there until this is over. Everyone turned the tides before, and now he's so much weaker.
This can all be over if we fight like hell to end it.

China's biggest oil company just hit a major solar breakthrough.
CNPC developed a perovskite solar cell with 25.05% efficiency—impressive on its own, but here's the bigger story: they're planning to pair it with silicon cells to slash energy costs. Pilot production starts 2026, mass production 2028.
Their goal? Match their oil output with renewables by 2035.

Multi state neurons
Robert Worden
https://arxiv.org/abs/2512.08815 https://arxiv.org/pdf/2512.08815 https://arxiv.org/html/2512.08815
arXiv:2512.08815v1 Announce Type: new
Abstract: Neurons, as eukaryotic cells, have powerful internal computation capabilities. One neuron can have many distinct states, and brains can use this capability. Processes of neuron growth and maintenance use chemical signalling between cell bodies and synapses, ferrying chemical messengers over microtubules and actin fibres within cells. These processes are computations which, while slower than neural electrical signalling, could allow any neuron to change its state over intervals of seconds or minutes. Based on its state, a single neuron can selectively de-activate some of its synapses, sculpting a dynamic neural net from the static neural connections of the brain. Without this dynamic selection, the static neural networks in brains are too amorphous and dilute to do the computations of neural cognitive models. The use of multi-state neurons in animal brains is illustrated in hierarchical Bayesian object recognition. Multi-state neurons may support a design which is more efficient than two-state neurons, and scales better as object complexity increases. Brains could have evolved to use multi-state neurons. Multi-state neurons could be used in artificial neural networks, to use a kind of non-Hebbian learning which is faster and more focused and controllable than traditional neural net learning. This possibility has not yet been explored in computational models.

Happy new year and all that. Maybe now's a good juncture to start looking into the usual new-year activities:
- Making some self-improvement resolution you won't stick to for more than a fortnight.
- Replacing the batteries in your fire alarm (with alkaline cells, not rechargeable!)
- Unsubscribe from all those marketing lists you've been binning for all of 2025.
- Be nicer to everyone and be nicest to the ones you love.

It's very sad, after more than a year of the current government, to read triumphalist press releases where they state they've basically done their job.
It at least acknowledges that longer sentence lengths contribute to an increase in prison population. i.e. prison overpopulation is broadly a policy choice that's independent of the number of actual cells.

Pera explained. “It comes down to genetic background.
Each strain has a unique genetic makeup that can either protect against or magnify the impact of that mutation.”

Remarkably, the neurons in the brains of these mice phenotypically matched what he had seen in the petri dish,

This interview with Philipp Ball hones in on the most interesting point of his book How Life Works.
Biological beings are not a kind of machine. Cells would not work if they were made out of tightly coupled cogs like in a mechanical living robot thing. Life on the molecular level is extremely fuzzy and things have multiple purposes all at once. I find that super hard to understand and yet infinitely interesting.
Beings are neither code nor machine but its own thing.

"users who leave their SSDs unpowered for over a year are risking the integrity of their data. The reliability of QLC NAND has improved over the years, so you should probably consider 2–3 years of unpowered usage as the guardrails. Without power, the voltage stored in the NAND cells can be lost, either resulting in missing data or completely useless drives."

It’s hard to articulate just how quickly batteries for grid storage are coming online.
These massive arrays of cells can soak up electricity when sources like solar are available and prices are low,
and then discharge power back to the grid when it’s needed most.
Back in 2015, the battery storage industry had installed only a fraction of a gigawatt-hour of battery storage capacity across the US.
That year, it set a seemingly bold target of adding 35 gigawatt-hours by …
