Lab's got new swag

💻⚙️ Atoms in semiconductors don’t just fall randomly into place, they self-organize in ways that change material properties. This discovery from our @molecularfoundry.lbl.gov & George Washington University could transform how we design microelectronics for quantum + defense tech. 🧪

‘Nickname’ is not ‘nick’ + ‘name.’ It was originally ‘ekename.’ ‘Eke’ was the Middle English word for “also” or “in addition.” Since ‘ekename’ began with a vowel, people used ‘an’ before it. Over time, 'an ekename' became 'a nickname.'

In a groundbreaking study researchers at JILA have demonstrated continuous lasing and strong atom-cavity coupling using laser-cooled strontium atoms. This innovative experiment opens new avenues for precision measurement and quantum technologies. jila.colorado.edu/news-events/...

Earlier this year, President Donald Trump issued an executive order and budget proposal aimed at cutting support for the scientific research community. How will possible cuts affect scientists, and what solutions may exist? This Thursday, join the Bulletin for an expert discussion.

At this exact time and date — 14:19 Eastern US time on September 22, 2025 — the center of the Sun is directly over Earth's equator (in technical terms, it has a declination of 0°), marking the moment of the September equinox. Happy equinox!

Happy Friday/weekend, everyone! It's time for the Photonics Hot List w @jmurphoton.bsky.social #photonics www.youtube.com/watch?v=iZUG...

A danger of parasocial relationships with AI is "now you're interacting with something that is designed to not challenge you," the CEO of Partiful, Shreya Murthy, says. "In-person relationships are supposed to actually have a little friction. That's how we build bonds." #TAF25 bit.ly/46mQI8B

Nobel laureate Jennifer Doudna tells Jeffrey Goldberg that vaccinations have been so successful that "there's been a collective forgetting that measles, and mumps, and rubella—these used to be diseases that would kill people in fairly large numbers." #TAF25 bit.ly/46a5DUE

In light of today’s news I’d like to remind you that this is a real newspaper clipping. History repeats itself when we don’t stop it.

🦖 Dinosaur egg dated directly For the first time, scientists have directly measured the age of a dinosaur egg using lasers. The fossil from China is about 85.9 million years old. 🔗 doi.org/10.1038/d415... #SciComm #Palaeontology 🧪

A DHS data-sharing platform used for sharing restricted intel among government agencies, law enforcement and fusion centers was misconfigured to allow access to "everyone" including tens of thousands of unauthorized government staff, contractors and foreign nationals. www.wired.com/story/a-dhs-...

Pythagorean Triple Square Day, as one man affectionately calls 9/16/25, is a day like no other this century.

🔥 The world’s top climate scientists have found that global warming is accelerating. Oceans are rising faster than ever, and the 1.5°C target is slipping away, but there’s still a narrow path forward. #ClimateAction

A strong QLM presence at the recent @instituteofphysics.bsky.social QuAMP 2025 conference in Newcastle. In addition to many contributed talks, @kjweatherill.bsky.social gave an Invited talk "radiofrequency and terahertz sensing and imaging using Rydberg atoms". Both Maddie & Tom won Poster Prizes.

Many publishers say AI Overviews tanked their traffic, but they can’t opt out of it without opting out of Google Search entirely. Google’s view? You’re not owed traffic so a traffic decline isn’t their problem. If your content can’t show up in snippets or overviews, then their product breaks so no.

We might be “experiencing an AI bubble,” Rogé Karma argues. “If that bubble bursts, it could put the dot-com crash to shame—and the tech giants and their Silicon Valley backers won’t be the only ones who suffer.”

I'm more than a little excited about this interstellar visitor 🧪 The images keep getting better and the insights deeper PS this is just some of the science funded by the NSF that is threatened by devastating budget cuts--speak up and call Congress. www.sci.news/astronomy/in...

Best glory I’ve ever seen from a plane! It’s an optical phenomenon that occurs when light interacts in and around tiny droplets of water in the clouds, in the direction opposite the sun. More complex than a rainbow. Here’s a link to some more info: www.zmescience.com/science/phys... #optics #physics

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia: doi.org/10.5281/zeno... We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical thinking, expertise, academic freedom, & scientific integrity. 1/n

All models have uncertainties, and some of these may be refined over the coming hours/next day, but here is the UK Met Office prediction for the filament CME arriving around September 6 at 19 UT. Models are generally agreeing on impact sometime between 9/6 18 UT and 9/7 4 UT.

Have a relaxing weekend, everyone!

Happy weekend—get it started with @jmurphoton.bsky.social's Photonics Hot List. #photonics www.youtube.com/watch?v=ATYX...

A federal judge in Boston said she found it "difficult to conclude anything other than that [the Trump administration] used antisemitism as a smokescreen for a targeted, ideologically-motivated assault on this country's premier universities, and did so in a way that runs afoul of [federal law]."

Solar is no longer “alternative energy.” It is the energy of the future. America risks remaining a petro-state, clinging to the past, instead of becoming an electro-state, embracing the future.

The U.S. Secretary of Energy does not know that electricity is energy. I'm glad we've gotten rid of DEI programs and are now giving America the leadership it deserves.

Google developer #1: "That's it. Our search engine is simple, efficient, and reliable. It's perfect. We're done." Google developer #2, presumably: "But wouldn't it be *more* perfect if the first search result was always a robot who mansplained your search results to you incorrectly?"

Bz has been trending south over the last 15 minutes or so... hopefully, this continues. If this Bz can sustain negative <-10 nT, we could charge up substorms and see some great aurora at mid-latitudes tonight over the U.S. Monitor webcams for real-time activity: go.theauroraguy.com/webcams

Periods of geomagnetic storms are expected through Tuesday, forecasters said.

Wow. Check this out. Politicians actually trying to solve problems can achieve a lot! www.washingtonpost.com/climate-solu...
