I heard that silicone is better for live imaging especially on longer acquisition. If you get the option to switch to a silicone objective maybe worth the try... Or buy yourself some other fancy imaging oil...to see if it's brand specific...
Good luck

Have you changed nail polish or slide sealant recently? Or has someone contaminated your oil with silicone? Not sure if they could react but, who knows...

When someone says „Scientists do not want you to know“ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

If you must declare your war then declare it and let civs evacuate long before the first bombs drop. What the actual fuck is this bullshit.

If you're in academia and you think we can just "ride this out," please read this #thread and think about how the current attacks on scientific research disproportionately affect junior researchers- who are literally the future.

Crick BioImage Analysis Symposium 2026

📣We’re back 🔬👀🖥️!
#CBIAS2026 returns 23–24 November 2026:
Join the bioimage analysis community to discuss advances in quantitative imaging & computational methods for image analysis. Great opportunity for early-career analysts & microscopists to present and connect.

I'm constantly trying (/failing) to get this point across.

If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.

If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.

Antibodies don't work.

NLRP3 is by far the most studied inflammasome — yet <30% of commercial antibodies were specific.

Only 4 of 14 tested antibodies detected NLRP3 specifically.

Antibodies must be validated before use.

Amen 🙏🏻 🤲🏻
A wise person once told me "all antibodies are non-specific until proven otherwise" I was just telling this to my students today 🤯

ChatGPT Health performance in a structured test of triage recommendations - Nature Medicine A stress test of ChatGPT Health triage revealed missed high-risk emergencies and inconsistent activation of suicide-crisis safeguards, raising safety concerns for consumer-scale deployment.

A new Nature Medicine study on ChatGPT Health isn't encouraging.

The system under-triaged 52% of emergencies, telling folks with DKA to wait 24-48 hours. It does fine on routine stuff, but fails at clinical extremes.
I'll take a deeper look 🧵

We humans are strongly influenced by the presence of companions over the course of our lives, shaping each other emotionally, culturally, or intellectually. This shaping effect is made literal in the case of stellar companions, which is the topic of today's Picture of the Week. The pair of points at the centre of the image, taken with ESO’s Very Large Telescope (VLT), are an old stellar couple — a binary system officially called AFGL 4106. As most stars are born in pairs, a big question for astronomers is how does being in a couple impact a star's death? Before dying, stars expel huge amounts of gas and dust, ingredients for a growing nebula. The massive stars shown here are at close yet distinct late stages of their lifecycles, with one having blown off enough mass to produce a dusty surrounding envelope. In a new paper led by Gabriel Tomassini, a PhD student at the Université Côte d’Azur (France), researchers have mapped this debris, shown here in orange, and precisely characterised the central stars (marked in black). Imaging astronomical objects close to stars poses a challenge due to the overpowering effect of a star's brightness and, in fact, the stars themselves appear in black as their brightness saturated the detector of the instrument used to make this image. Fortunately, the SPHERE instrument on the VLT is well equipped to deal with large contrasts in light levels, enabling a detailed study of both the high luminosity stars and the faint surrounding nebula for the first time. Moreover, it can correct the blur caused by atmospheric turbulence, delivering very sharp images. The shape of the nebula reveals the significant impact the companion is having on the gas ejection of the dying star, introducing asymmetries and shifting the clouds of gas and dust away from a perfectly spherical shape. Further observations of star systems like this one allow scientists to better understand how the presence of companions affects the death of stars.

Très fier de Gabriel Tomassini, mon doctorant, pour cette image extraordinaire.
AFGL 4106, deux étoiles à 10000 années-lumière, ont vécu ensemble et meurent ensemble, formant cette étonnante nébuleuse grande comme 15 000 fois la distance Terre-Soleil. Voici les derniers moments de leur vie.

Reminder that I will be speaking this Wednesday about my postdoc work. You have been warned. 🧪

Question is, will it be Wednesday Addams themed? 🥸🫥🌚👻

I mean, you can't do worse than an anti-vax anti-meds health secretary (or whatever) and a dictat0r as 'president' of the land of the free...

Could the US be the source of the cosmic anti-matter, by this point 🤔?
