Hunting Hidden Particles with Light
![An experiment seeks to produce dark photons through the collision of a 3 GeV electron beam with a laser operating at the [latex]\mathcal{O}(\mathrm{eV})[/latex] scale, while X-ray detectors primarily register background photons-a signature indicative of the challenge in isolating these elusive particles.](https://arxiv.org/html/2603.00247v1/2603.00247v1/x6.png)
A new experiment leveraging electron-photon collisions aims to reveal the elusive nature of dark photons and other particles from the hidden sector.

I absolutely loved a piece of parenting advice I heard recently! The actress from Better Sister shared it on The Drew Barrymore Show, and it really resonated with me. She said you can’t try to do two things at once when you’re with your kids. Like, if I’m down on the floor playing with my little one, that’s all I’m doing. No checking my phone, no glancing at work emails, just pure, focused playtime. It’s such a simple idea, but it’s made a huge difference for me!
The DTCC notice dropped like a lead balloon, confirming Ripple’s prime brokerage is now plugged into Wall Street’s ancient clearing system. A move that could revolutionize crypto flows-or just make accountants yawn.

According to the Clark Moody Dashboard-a name that sounds like a 19th-century industrialist with a penchant for spreadsheets-19,996,979 BTC have been mined. A mere 3,000 BTC remain before the 20 millionth coin emerges, a week away at current rates. Once this threshold is crossed, more than 95% of the sacred 21 million supply will be in circulation, leaving just 1 million coins to be mined over the next century. A century! Enough time for humanity to forget why it cared in the first place.

Scarlett Johansson’s latest film, Jurassic World Rebirth, has become the most popular movie on Netflix in the United States. Since its release on February 28th, it quickly rose to the top of the streaming charts.

New research explores how the mathematical structure of quantum systems determines the strength of their non-local connections, revealing conditions for maximal Bell inequality violation.
However, in its latest market commentary, Grayscale Investments, that paragon of wisdom, noted that now may be an appropriate time for long-term investors to consider allocating their hard-earned coins to crypto. A proposition as enticing as a snake in a boot, but perhaps there’s merit in it.
Researchers have demonstrated that precisely controlling the phase of superconductivity in nickelate materials through nano-patterning can induce unusual metallic behavior and reverse the material’s directional superconducting properties.

Koo Yun-cheol, South Korea’s Deputy Prime Minister and Minister of Finance (a man who likely owns a calculator with feelings), solemnly swore to “review” how the government manages seized crypto. Because nothing says “trust us” like a bureaucratic promise whispered into the void.

The Evil Dead star said he’s been diagnosed with “a type of cancer that’s ‘treatable’ not ‘curable.'”
