Submission + - Thorny issue plaguing lithium-ion batteries laid bare in new study (phys.org)

Submitted by alternative_right
alternative_right writes: Lithium dendrites, i.e. tiny crystalline thorns that grow off of lithium-ion battery anodes during charging, have been a persistent challenge for the world's most widely used form of energy storage. "Dendrites can penetrate the battery's separator, causing catastrophic short circuits and safety hazards," said Qing Ai, a former research scientist at Rice University who is a first author on a new study published in Science that reports for the first time exactly how these tricky structures behave inside batteries. "Despite decades of study, the fundamental nanomechanical properties of lithium dendrites remained a mystery—until now."

Submission + - Executives say AI boosts productivity but the real gain is just 16 minutes per w (nerds.xyz)

BrianFagioli writes: A new study suggests the productivity boost from artificial intelligence may be far smaller than executives claim. According to research cited in Foxitâ(TM)s State of Document Intelligence report, while 89 percent of executives and 79 percent of end users say AI tools make them feel more productive, the actual time savings shrink dramatically once people account for reviewing and validating AI-generated output.

The survey of 1,000 desk-based workers and 400 executives in the United States and United Kingdom found executives believe AI saves them about 4.6 hours per week, but they spend roughly 4 hours and 20 minutes verifying those results. End users reported a similar pattern, estimating 3.6 hours saved but 3 hours and 50 minutes spent reviewing AI work. Once that âoeverification burdenâ is factored in, executives gain just 16 minutes per week, while end users actually lose about 14 minutes.

Lying to yourself is the biggest danger for trying to stay Anonymous. With enough patterns to recognize, the idea that one can hide is a delusional take.

The only way to win, is to run EVERYTHING you post through an AI that changes the tone and words used in all your online activity. But even then that may itself be a lie.
