AI voice scams can sound like your child, your parent, or a close family member asking for help right now. This guide explains how scammers clone voices, why the calls feel so real, and the simple steps that help you slow down and verify before money moves. Read more:

@jawwwn_ Good point Peter. Not sure about the whole antichrist thing 🙄

Peter Thiel: “Ambition is not considered cool in Europe.” “You’re always supposed to downplay that.”

@MargoMartin47 @PressSec @POTUS I’m going to Graceland! Memphis, TN 🎶

“I love Elvis!” @POTUS President Trump announces he is touring Graceland today 🇺🇸🎶

This #WorldMetDay, I join @UN & @WMO SGs in the call to protect our tomorrow. Through our work we contribute to global observations, strengthen connectivity and #DigitalLifelines, and accelerate #EarlyWarningsForAll so everyone at-risk receives life-saving alerts in time to act

@SecretaryLCD @EDSecMcMahon @USDOL @usedgov So happy to see this! What a wonderful idea and a great way to raise up our countrymen (and women) ! 🇺🇸❤️

Thank you to my friend @EDSecMcMahon for visiting us at the Department of Labor's HQ last week 🇺🇸 I’m excited about the partnership we’ve established between @USDOL and @USEDGOV. Together, we are focused on training and preparing the future workforce of America by bridging the gap between education and employment.

@m_zettersten Congratulations and very well deserved! 🎉🥳🎊

Honored to be in such great company, what a fun list! Feeling grateful for all of the mentors/collaborators/friends who share so much light

@elonmusk No introspection == murder. I never know with you guys what stupid take you’re gonna come up with next.

Reinforcing negative neural pathways via therapy or introspection is a recipe for misery. Don’t cut a rut in the road.

@elonmusk What?????

Huge gratitude to Valentina Emiliani @EmilianiLab, Eirini Papagiakoumou, and the incredible lecturers and TAs of the course on “All-Optical control of brain functioning with Optogenetics and multi-photon microscopy” here in Paris. The class took us on a deep dive into 2p imaging and holography--starting from the basics of how a lens works (I did not know a lens computes a fourier transform!), and progressing to advanced methods including 3d holography with temporal focusing, voltage imaging, tricks to minimize heating, etc. We got hands-on experience though an amazing set of labs (including closed loop feedback holographic stimulation through a GRIN lens in a freely moving mouse). The entire experience was incredible, and I highly recommend for anyone interested in this frontier of neurotechnology. It was so much fun to be a student again!

⭐️ New preprint — work led by @mdunnhofer , supported by Jean de Dieu U. biorxiv.org/content/10.648… In natural scenes, objects are often hidden by clutter, occlusion, or camouflage. Yet humans can suddenly “see” them the moment they move. To study this, we leveraged the 𝗠𝗢𝗖𝗔 (Moving Camouflaged Animals) dataset — a unique set of videos where objects are nearly invisible in static frames but become perceptually clear through motion. In our new work, we asked: 👉 Do modern AI systems rely on motion the same way we do? We brought together: • 🧑🏽‍💻👨🏽‍💻Human behavior • 🐒🧠Macaque IT neural recordings • 🤖Image-based and video-based neural networks Here’s the surprising part: Image-based neural networks are already very good at estimating object properties — even in these highly challenging, camouflaged scenes from MOCA. But that’s exactly the problem. Because they perform so well using static cues alone, they don’t need to rely on motion the way biological systems do. As a result, they fail to show the strong motion-dependent improvements seen in humans and the primate brain. Video models partially recover this behavior by integrating information over time — but still fall short of fully matching biological vision. The takeaway: Better performance does not mean better models of the brain. In fact, being “too good” at static recognition may push models toward the wrong computational strategies. Datasets like MOCA expose this gap clearly: 👉 Humans sometimes need motion to see. 👉 Models often don’t. If (we might not) we want AI systems that truly reflect how primate vision works, we need to go beyond static benchmarks and capture the dynamic computations that stabilize perception in the real world.

@swfstoptraffick @JasonRothermund @ali_hopper @taraleerodas @JJCarrell14 Cool. Would be awesome to have more people representing other communities, in order to have a deeper understanding of how culture influences this epidemic.

Join us over the next few days, as we introduce our “National Advisory Board” members for Shepherd’s Watch Foundation. These leaders bring decades of experience in homeland security, military operations, law enforcement leadership and federal policy. We are honored to have them sit at our table!

We are incredibly proud to witness this historic moment for The Miss Universe Organization. For the first time in our history, a Miss Universe stood at Harvard to share a message that goes far beyond the crown . A reminder that true power lies not in perfection, but in purpose, voice, and the courage to redefine what is possible for women everywhere. 👑✨

@fffiloni welcome back dall-e! we missed you 🤗

What's needed now is collective will, fueled by the urgency of a widening AI divide. Because behind every network we build, every innovation we create, every policy we shape are people. And they are counting on us.

Reliable water means strong farms and more stable food prices. Thanks to @POTUS’ One Big Beautiful Bill, we’re investing $889 million in Western water infrastructure to support agriculture and keep costs down. Watch how this is strengthening communities across the West:
