America’s kids deserve classrooms with air that protects their health. Poppy, an ARPA-H BREATHE performer, is helping build a powerful early-warning HVAC system for pathogens in shared spaces like schools. We’re excited to see Poppy featured in the @sfexaminer for their work to keep students breathing healthy air in schools. @TaliaPGurevich sfexaminer.com/news/public-he…

@Mizala2026 @FCEIUchile Exacto!

En el Foro de Candidatas y Candidatos a la Rectoría de la Universidad de Chile, organizado por el Campus Juan Gómez Millas y la Facultad de Comunicación e Imagen @FCEIUchile, destaqué que, en el contexto de la irrupción de la inteligencia artificial, las ciencias sociales, las humanidades y las artes adquieren un valor aún mayor, pues son clave para formar estudiantes capaces de pensar, crear y ejercer una mirada crítica. #MizalaRectora #UniversidadDeChile #debateuchile

@drseanmullen Thank you!

I realized something the other day that kind of stopped me in my tracks. A lot of the people I grew up looking up to… didn’t make it out. River Phoenix. Kurt Cobain. Bradley Nowell. That was the early pattern. Raw talent. Fast burn. No off-ramp. Then you grow up and think, okay… that was youth, excess, the 90s, whatever we want to call it. But then it keeps going. Chris Cornell. Robin Williams. Anthony Bourdain. Different era. Different lives. Same outcome. And that’s when it stops being a coincidence and starts forcing a question: What are we actually rewarding as a culture? Because these weren’t people on the margins. These were people at the top of their craft…creative, driven, perceptive to a fault. The kind of people who see too much. And maybe that’s part of it. We celebrate intensity. We platform people who can feel deeply, think sharply, create relentlessly… …but we don’t build systems that help them live with that wiring. We turn their output into identity. We consume the product. We mythologize the struggle after the fact. But in real time? We normalize burnout. We romanticize suffering. We mistake visibility for support. And here’s the part that hits hardest for me: You can have influence, money, recognition… and still be completely unprotected from your own mind, your own biology, your own environment. That’s not a moral failure. That’s a systems failure. So when I look at that list, I don’t just feel sadness. I feel like it’s a warning. Not about fame. Not about art. About the gap between what we admire… and what we actually sustain. We need to get better at closing that gap. Because “brilliance” without protection isn’t a gift. It’s a risk factor.

@MeetJess @sasswashere 💯%

6 years of living with the constant math:
Is this space safe?
Is this air clean?
Is this risk worth it? 6 years of watching caution get mocked,
science get diluted, preventable harm get normalized. I’m not tired of caring. I’m tired of being surrounded by people who don’t

@AP @kprather88

For decades, billions of gallons of sewage and industrial waste have been dumped into the Tijuana River. Recent research shows this chronically contaminated watershed in Southern California is also polluting the air.

Hi @Astro_Ayers , do you think the Orion entry will be noticeable from Hawaii?

@1goodtern Hawaii

@1goodtern Yesterday I checked for Hawaii and California, same thing. I hope it holds.

Scottish Covid wastewater now at its lowest point since the summer of 2020. This is good news. It's reflected in both positivity and positive tests too. Probably genuinely the lowest rates of Covid since the first summer. Hard to predict what's around the corner, but I suspect that the wave of BA.3.2 that passed through the kids has nerfed community transmission here for a while. It feels strange to be hoping I'm right.

The @HawaiiDOH and Hawaiʻi District Health Office are working with the Centers for Disease Control and Prevention (CDC) to investigate a report of high rates of a serious bacterial infection called invasive Group A Streptococcus (iGAS) in West Hawaiʻi. health.hawaii.gov/news/newsroom/…

Spot the viscacha 🔍🐇 Somewhere in this 📷 of NSF–DOE @VRubinObs is a viscacha — a furry, rabbit-like rodent related to chinchillas. It’s well-camouflaged for the foothills of the Chilean Andes, don’t you think? 📷NSF–DOE @VRubinObs/NOIRLab/SLAC/AURA/I. Sullivan

@SolidEvidence @Lee_CrollPhD 0-2 were probably born to parents who have had c19.

@Lee_CrollPhD It seems like there should be an obvious explanation, but it's counterintuitive. It's the people with multiple exposures (adults) that should be resistant to something new and evolved (BA.3.2), but it's the opposites. Suggesting this isn't an immunity thing.

I’m amazed. It’s really true: the BA.3.2 COVID lineage is infecting children at a much higher rate than previous lineages. I’m late to this party, but I couldn’t really believe it was true until I did the analysis for myself. 1/

@mageeclegg If you had finished your piscola first, you would have been virtually fluent 🥃

I thought I spoke proper Spanish… Then I moved to Chile 🇨🇱 First week there, a guy tells me: “Weón, cacha la weá fome… pero bacán igual.” I understood nothing… just stood there sipping my piscola. Turns out… these words actually mean something: • weón = dude… or idiot • cacha = understand • weá = thing • fome = boring • bacán = awesome Then I realized… I’d been learning the wrong version of Spanish this entire time… and Chile 🇨🇱 might be the only place on earth speaking real Spanish.

@ukhadds 👌

@LAalejandro Oops, good catch! You’re right, the volume should be the 196 and the surface be 205. S/V is correct.

Aerosols are very small, have a high surface to volume ratio and can readily reach super saturation. This combination makes them a unique environment for chemical reactions. We had a paper published in JACS that looked into the rate of chemical reactions within and on aerosols.

@ukhadds *Increased surface, same volume (for the 2 droplets)

If you were to divide the sample into two levitating balls of fluid, the surface to volume ratio would continue to increase.

@hoolie_r I would try testing with a different batch. Years ago, I got a few very faint lines, w/o exposure, no clear reason to suspect c19. I tried different batches and they came back -.

Okay, covid peeps. I’m trying not to freak out. I have no symptoms but just took a preventative, safety Flowflex covid test. I just flew on a plane 3 days ago. Test 1 I see a super faint line. I took a second and see nothing. So I took a third and can’t tell but I think nothing
