We will put an excellent determine on how a lot we all know in regards to the universe: 5%. That’s how a lot of what’s floating about within the cosmos is unusual matter—planets and stars and galaxies and the mud and gasoline between them. The opposite 95% is darkish matter and darkish power, 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 power stay shrouded in a blanket of questions—critically, what precisely are they?
Enter the Vera C. Rubin Observatory, certainly one of our 10 breakthrough applied sciences for 2025. Boasting the most important digital digicam ever created, Rubin is anticipated to review 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 power, Rubin may slim down current theories on what they’re manufactured from. Right here’s a have 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 methods massive language fashions (LLMs) into doing one thing they’ve been educated to not, comparable to assist anyone create a weapon. And Anthropic’s new strategy could possibly be the strongest defend 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 sudden output. Regardless of a decade of analysis there may be nonetheless no approach to construct a mannequin that isn’t susceptible. However, as a substitute of making an attempt 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.
