Influence of Environmental Surroundings on the Mechanical Properties of Ultrathin Polymer Membranes We review the impact of temperature, pressure, and liquid/gas environments on the mechanical properties of ultrathin polymer films. Understanding how they influence the mechanical properties will be ....

This spring I challenged myself to write my first perspective article about ultrathin polymer film mechanics. I had a lot of fun writing it. I think there are some interesting questions that are still out there. doi.org/10.1002/pol....

A screenshot of my spacetime diagram web app, showing diagrams describing the same events and motion in two different inertial frames ("Home Frame" on the left and "Other Frame" on the right). Each diagram shows a "graph paper" grid with the vertical axis labeled "t" or "t prime" and the horizontal axis labeled "x" or "x prime". Faintly in the background of each is a tilted diamond-like grid showing the coordinate grid of the other frame. Each diagram shows three lines going up the page (toward higher t), but they go straight up in the Home Frame and up along parallel diagonal lines in the Other Frame. There are also 45° lines going upward from a shining event marked at the origin. A yellow horizontal line is drawn across each diagram at the same height somewhere in the middle. Below each diagram is a flat panel showing the locations of each object at the time corresponding to the height of the yellow line: two firecrackers, a person with green hair in the middle, and a couple of blue dots between them. In the scenario below the Other Frame diagram, the firecracker on the left has just exploded.

1/? Ever wanted to understand Einstein's theory of special relativity? I'm feeling remarkably proud of a web page/app I've written that introduces the idea using "spacetime diagrams" (and lets you play with them yourself).

Critics of de-extinction research hit by mystery smear campaign Several researchers who have been critical of Colossal Biosciences’ plans to revive extinct animals say they have been targeted by online articles trying to discredit them

Thanks @newscientist.com for shining a light on the smear campaign against @toriherridge.bsky.social, @devoevomed.bsky.social, @flintdibble.bsky.social & myself just for fulfilling our critic & conscience role to provide expert commentary about de-extinction www.newscientist.com/article/2490...

I vote De Goose, but daughters are both for Gooseteau.

It happened again yesterday: I informed someone they were Canadian who didn’t know they were Canadian. This has now happened about 10 times for me. Americans, take note: if your parent was a Canadian citizen born in Canada, you are a Canadian citizen. And there’s a law working its way through…

The cover picture depicts a firefly (BSJ-04-146) luring a moth (FAK) to the carnivorous plant (proteasome) and was designed by DrawImpacts.

We turn complex science into striking visuals, like this cover we illustrated for Dr. @behnamnabet.bsky.social et al. on FAK inhibitors and PROTACs. 🦋

Many people enjoy themselves around posters. A band plays a Green Day cover in the distance.

ESMC2025 even has Green Day, why would you not come to Lyon?

Ticks on the rise: Strategies for preventing disease | Harvard T.H. Chan School of Public Health Time

I will be moderating a a discussion with several experts this afternoon on ticks. We will be talking about the rise of these pests and the dangers they pose. It's free and online. Love to see you there! hsph.harvard.edu/events/ticks...

Building a monostable tetrahedron In this short note we describe what we believe to be the first working model of a monostable tetrahedron.

This is fun. Do there exist tetrahedral objects that will only rest stably on one of its four faces, tumbling spontaneously under gravity until it rests on this one? These authors say they have found such an object.

🧪🔭 It's conference season, so if you're giving a talk this summer: please check out the "Colour Blindness Simulator" – an accessibility tool where you can upload slides & ensure they will be visually legible to people with different types of colour blindness. It's a quick act but it really helps! ⬇️

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years.

NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Bonnne chance!

Our first flight yesterday was inside the tornadogenesis and growth phase of a soon-to-be wedge tornado near Spiritwood and Jamestown, ND. Data and more video will be shared as we process material.

Some good storms rolled through last night! Hopefully the hail didn't murder my garden.

I got a new toy for the lab, and it is fuuuuun!

Today is 200 years since Faraday's discovery of benzene! I made these hexies for a maths community quilt (with the maths being in the bond lengths of single and double bonds and the aromatic structure). I don't believe ever got made, so it's nice to have an opportunity to post a picture of them! 🐡

Bravo Benoit!

Not a bad day for an ONR review.

Predicting When Ketchup Will Start Flowing For a wide range of complex fluids, the transition from solid-like at rest to liquid-like when pushed can be predicted from properties of the at-rest state.

Researchers have shown that the point at which ketchup, toothpaste, and other complex fluids undergo a solid-to-liquid transition can be predicted from the properties of the substance while it is still a solid. The insight could guide the control of this industrially important class of fluids.

When you make working conditions at a university worse the better faculty leave. Shocked face.

This is really bad for everyone.
