A shocking explanation for tape’s distinctive screech High-speed video reveals how fast-moving cracks in tape’s adhesive layer produce shock waves that make the stuff sing as it unrolls

Do you find the sound of peeling tape annoying? Or oddly satisfying? 📦🧪

✍🏽 For @science.org, I wrote about a new study where scientists have figured out why it makes that distinctive screechy sound. www.science.org/content/arti...

New paper shows social scientists are sidelining null results. Analysing 100,000 articles across 150 political science journals, it finds 2% of abstracts report null-only findings; >90% highlight significant results.
Researchers 10–100x less likely to spotlight nulls: driver of publication bias.

Earth’s Climate May Go from Greenhouse to Hothouse - Eos Uncertainty in climate models could mean Earth systems are perilously close to their tipping points, scientists warn.

Uncertainty is not your friend: In a new paper published in One Earth, scientists argue that uncertainties in climate projections mean Earth system components could be at a higher risk than we think of reaching crucial tipping points. 🌊

In Memory of Katherine Wright | Physics Magazine We pay tribute to our friend and colleague, whose journalistic talent and commitment to inclusivity left an indelible mark on Physics Magazine.  

Katherine was an intellectually intrepid writer and editor. She had great ambitions for what physics journalism could be and she pushed those around her to meet that mark, as this eulogy attests. It is just devastating to lose her.

Thanks to @dirkbwalther.bsky.social and @mickbonner.bsky.social for their time and insights.

Easy on the eyes is also easy on the brain A new study finds that the brain spends less energy processing scenes that people find aesthetically pleasing.

Why do we find some scenes more aesthetic than others?

For my first in @sciencenews.bsky.social, I wrote about a new study that suggests that our aesthetic preferences could have evolved as cognitive shortcuts. 🧠🧪

2025 Roundup: Bats, squid, and icebergs Five stories that I had the most fun researching and writing in 2025.

🧪 Last year, I learned about how squid get their spots and why icebergs flip while writing two of the five stories on this list. Rhttps://www.sachinxr.com/2025-roundup-bats-squid-and-icebergs/

Have a look through this gallery to see one of the coolest examples of role specialisation in the insect world 🐜

They live inside twigs with small circular entrances & these workers have evolved heads the perfect shape to block those entrances - effectively, they are living doors!

Spotted on LinkedIn... a bad AI summary of our new paper on risks of AI in research.

Please make it stop.

Recreating Iceberg Flips in a Lab Experiments with small, floating slabs of ice have revealed melting-induced shape changes that may explain why icebergs sometimes flip over.

🧊 Icebergs can sometimes suddenly flip over. But why does that happen?

✍🏽 New for @physicsmagazine.bsky.social: A new experiment recreating iceberg flips in the lab suggests that changes in shape due to melting determine if and how an iceberg tips over. 🧪 physics.aps.org/articles/v18...

Bats may mistake wind turbines for open sky, causing deadly collisions Study may help explain why giant blades kill millions of the animals every year

Wind turbines kill a massive number of bats. These animals seem to be unusually attracted to turbines, and researchers have long puzzled over why. 🦇🧪

For @science.org, I wrote about a new study that suggests they might be responding to a visual cue. www.science.org/content/arti...

Are you a materials scientist or engineer working on optical material sensors? Have some ideas on how they could power the sports wearable of the future?

If so, I'm looking to speak with you for an article in Photonics Focus. #JournoRequest

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

Cicadas Decide to Sing with a Little Help from Their Friends The daily start of a cicada’s mating call is triggered by the amount of light in the sky and also by the behavior of nearby insects.

Researchers studied recordings of cicadas to discover that the insects’ singing is synchronized with the Sun's position in the sky. The rapid rise in volume suggests that each cicada starts singing in response to both the light level and its neighbors' behavior.

Thanks to De-Ming Liu (one of the study authors) and @robjohnnoble.bsky.social for the comments.

Game-Theory Paradox Inspires Cancer Therapy Simulations suggest that the combination of two cancer-therapy strategies, which individually deliver poor outcomes, might produce optimal results.

🧪 Often, in a counterintuitive phenomenon called Parrondo’s paradox, two losing strategies can be combined into a winning one.

A do-or-die moment for the scientific enterprise Reflecting on our paper “The entities enabling scientific fraud at scale are large, resilient, and growing rapidly”

Today, our article "The entities enabling scientific fraud at scale are large, resilient, and growing rapidly" is finally published in PNAS. I hope that it proves to be a wake-up-call for the whole scientific community.

The Secret Disorder of Squids A structural phenomenon traditionally confined to inanimate systems has now been observed in biology.

Many densely packed systems have a hidden structure. They seem random, but become uniform as you zoom out. Conversely, variation increases with scale in hyperdisorder. 🌌 🧪

✍🏽 New for Physics Magazine: A new study reports the first example of hyperdisorder in biology. physics.aps.org/articles/v18...

The Secret Disorder of Squids A structural phenomenon traditionally confined to inanimate systems has now been observed in biology.

Physics Magazine writes about our research on hyperdisordered patterns. Thanks @sachinxr.bsky.social for the article and @davidbrueckner.bsky.social for the quotes!

The only problem is that the citations go to papers that don't actually exist.

Colossal Biosciences Can't Have It Both Ways | Defector On April 7, the New Yorker and Time ran nearly identical stories that might be better described as press releases for the de-extinction company Colossal Biosciences. The two stories differed slightly:...

Astronomical twilight on Mars, including the moon Deimos. Taken by the Engineering Cameras aboard the Perseverance Rover.

No AI, this is a real photo taken by Percy’s engineering cameras of astronomical twilight on #Mars! You can see Deimos in the sky too.

I worked pretty hard to plan, execute, and analyze this image, and it came out beautifully! A bit noisy, but it was very dark out after all.
