Solid-state batteries
The rise of the lithium-ion battery, which powers everything from the smallest personal electronics to gargantuan energy storage systems, has been nothing short of revolutionary. But as anyone who’s boarded a plane in the last decade could tell you, storing and pumping out energy by moving charged lithium ions through a liquid electrolyte soup has…
Cleaning up PFAS
Scrubbing Earth of per- and polyfluoroalkyl substances—a.k.a. PFAS or forever chemicals—could eliminate a list of woes for people and planet. Used for decades in everything from nonstick pans to firefighting foams, PFAS have been linked to increased risks of fertility challenges, developmental delays, cancer, and reduced immune response. They are known for a strong bond…

Nuclear-powered spaceships
Just before the Artemis II crew began its historic slingshot around the moon this past April, NASA announced plans to build Space Reactor-1 Freedom. SR-1, the first-ever nuclear-reactor-powered interplanetary spacecraft, is meant to fly an uncrewed mission to Mars by the end of 2028, arriving in 2029. A successful mission would herald a new era…
We can do impossible things
I’d wager everyone has a rehearsed response to what’s absolutely one of the world’s worst interview questions: “What’s your biggest weakness?” Whenever I’ve gotten it, I take a slow—even pensive—breath and rattle off my line: “I say no to myself too much.” I won’t lie. It’s a bit shameless—a definite humblebrag. I’m a systems thinker:…
Windows 10 faisait plus simple, mais Microsoft a une nouvelle idée pour la barre des tâches de Windows 11
Microsoft teste un nouveau menu pour déplacer la barre des tâches de Windows 11 sans passer par les Paramètres. Une manipulation plus rapide, mais toujours moins intuitive que sur Windows 10.

Ces résultats illustrent les enjeux du référencement sur Reddit, jusque dans les réponses des IA.

Votre Smart TV est devenue un panneau publicitaire ? Des utilisateurs demandent à l'IA de faire le ménage
Publicités, recommandations sponsorisées, applications imposées… Les interfaces des téléviseurs connectés finissent par agacer certains utilisateurs. Au point que des développeurs utilisent désormais l'intelligence artificielle pour leur rendre une interface plus simple. Un projet open source baptisé CleanYour.tv illustre cette nouvelle manière de reprendre la main sur son téléviseur.
