Lithium-sulfur battery advancements promise faster charging and longer life

In the first study, a team led by Professor Jong-sung Yu at the DGIST Department of Energy Science and Engineering developed a nitrogen-doped porous carbon material to enhance the charging speed of lithium-sulfur batteries. This material, synthesized using a magnesium-assisted thermal reduction method, acts as a sulfur host in the...

When the clocks change for Daylight Saving Time, and why we do it at all

The clocks on our smartphones do something bizarre twice a year: One day in the spring, they jump ahead an hour, and our alarms go off an hour sooner. We wake up bleary-eyed and confused until we remember what just happened. Afterward, "Daylight Saving Time" becomes the norm for about eight months (And yes, it's called "Daylight Saving" not "Daylight Savings." I don't make the rules). Then, in the fall, the opposite happens. Our clocks set themselves back an hour, and we wake up refreshed, if a little uneasy. Mild chaos ensues at both annual clock changes. What feels like an abrupt and drastic lengthening or shortening of the day causes time itself to seem fictional. Babies and dogs demand that their old sleep and feeding habits remain unchanged. And more consequential effects — for better or worse — may be involved as well (more on which in a minute). Changing our clocks is an all-out attack on our perception of time as an immutable law of ...

The Shortcut AI Excel agent could one-shot spreadsheet jobs. Heres how to try it.

There's a new AI agent on the block for people who spend their waking hours inside spreadsheets. Navigate to Shortcut AI's website , and you'll find a page that looks almost exactly like an empty Microsoft Excel spreadsheet. The main difference is a sidebar chatbot that can be tasked with taking on the tedious legwork of building, say, complex financial models or competitive analyses. Because Shortcut is agentic , meaning it can handle multi-step tasks on the user's behalf, the tool can do more than just generate Excel formulas or analyze spreadsheet data. In a demo on X, Nico Christie, founder and CEO of the Shortcut AI agent, showed how the tool swapped out the data from a Microsoft distributed cash flow analysis (DCF) for Google data by looking up Google's SEC filings and populating the data in the same template. This Tweet is currently unavailable. It might be loading or has been removed. Shortcut launched on Monday with a rather ominous tagline: "Try...

Mystery Pixel smartphones detailed in code references

The devices also pack 12GB of RAM apiece. Shiba is said to feature a screen with a resolution of 2,268 x 1,080 pixels while Husky could be a bit larger at 2,822 x 1,344 pixels. Given the amount of RAM, however, both would likely qualify as premium devices. from TechSpot https://ift.tt/cefMDJW via
