The opposite 95% is darkish matter and darkish vitality, two mysterious entities aptly named for our incapacity to make clear their true nature.
Earlier work has begun pulling aside these dueling forces, however darkish matter and darkish vitality stay shrouded in a blanket of questions—critically, what precisely are they?
Enter the Vera C. Rubin Observatory, one in all our 10 breakthrough applied sciences for 2025. Boasting the most important digital digital camera ever created, Rubin is predicted to check the cosmos within the highest decision but as soon as it begins observations later this 12 months. And with a greater window on the cosmic battle between darkish matter and darkish vitality, Rubin may slim down present theories on what they’re made from. Right here’s a take a look at how.

Anthropic has a brand new approach to shield massive language fashions in opposition to jailbreaks
What’s new? AI agency Anthropic has developed a brand new line of protection in opposition to a standard type of assault referred to as a jailbreak. A jailbreak tips massive language fashions (LLMs) into doing one thing they’ve been educated to not, similar to assist anyone create a weapon. And Anthropic’s new strategy may very well be the strongest protect in opposition to the assaults but.
How they did it: Jailbreaks are a type of adversarial assault: enter handed to a mannequin that makes it produce an surprising output. Regardless of a decade of analysis there’s nonetheless no approach to construct a mannequin that isn’t susceptible. However, as a substitute of attempting to repair its fashions, Anthropic has developed a barrier that stops tried jailbreaks from getting by way of and undesirable responses from the mannequin getting out. Learn the total story.
