The way that electrons paired as composite particles or arranged in lines interact with each other within a semiconductor provides new design opportunities for electronics, according to recent findings in Nature Communications.
What this means for semiconductor components, such as those that send information throughout electronic devices, is not yet clear, but hydrostatic pressure can be used to tune the interaction so that electrons paired as composite particles switch between paired, or “superconductor-like,” and lined-up, or “nematic,” phases. Forcing these phases to interact also suggests that they can influence each other’s properties, like stability – opening up possibilities for manipulation in electronic devices and quantum computing.
“You can literally have hundreds of different phases of electrons organizing themselves in different ways in a semiconductor,” said Gábor Csáthy, Purdue professor of physics and astronomy. “We found that two in particular can actually talk to each other in the presence of hydrostatic pressure.”
Nature article presents an AI developed by Google’s Medical Brain team which outperforms hospitals’ own warning system in predicting the death risk among hospit…al patients.
Google’s Medical Brain team is now training its AI to predict the death risk among hospital patients — and its early results show it has slightly higher accuracy than a hospital’s own warning system.
Bloomberg describes the healthcare potential of the Medical Brain’s findings, including its ability to use previously unusable information in order to reach its predictions. The AI, once fed this data, made predictions about the likelihood of death, discharge, and readmission.

Glossing over the fact ageing is a chronic decline in function won’t help with anything, let alone ending ageism.
At times, I think that I have written enough rejuvenation advocacy articles and that every time I write a new one, I’m just repeating myself. I sometimes say to myself that I’ve written about concerns and misconceptions from so many angles that I’ve probably exhausted all the options. However, from time to time, there comes the bittersweet reassurance that I’m not going to be out of a job any time soon.
The culprit
A contentious proposal to link oversight of California’s electric grid with other western states faces a crucial test Tuesday in a state Senate committee.
Supporters say regionalizing the grid would make it easier and cheaper to deploy renewable energy across the western United States. But critics, including some environmentalists and consumer advocates, say California would jeopardize its efforts to require the expansion of renewables.
California has greatly expanded the use of renewable energy sources, particularly wind and solar, but that’s brought new challenges for grid operators to manage supply and demand as weather patterns and sunlight vary.
