Got bugs? Here’s how to catch the errors in your scientific software Computer scientists share their advice for ensuring that your scientific software does what it’s supposed to do.

Commercial software can contain 50+ errors per 1000 lines of code; scientific software, written by relative newbies, is more error prone. I spoke to @tracykteal.bsky.social @amyko.phd @weecology.bsky.social & more to learn best debugging practices @nature.com 🧑‍💻 🐜 ❌ 🧪 www.nature.com/articles/d41...

"'No' is a really powerful word for scientists, because it makes you kind of think around corners." A fascinating story about how DNA is helping researchers study manuscripts not just for the words they contain but what they tell us about the ancient world in which they were made. @nature.com

This is a neat trick, Crystal, thank you! But what's the advantage of using labelling vs mutate() -- that is, adding a new col with the label name rather than labelling per se? Just curious, thanks!

When career anxiety becomes gameplay: lessons from China’s ‘young-faculty simulator’ A popular online game simulates life as an academic — and throws the challenges of being an early-career researcher into sharp relief.

"You chase grants, publish papers, recruit students, handle teaching and manage relationships, all while trying to keep your mental health from hitting zero." New @nature.com, a researcher reflects on art imitating reality in a popular "young faculty simulator". 🧪 www.nature.com/articles/d41...

Idaho governor signs law making transgender bathroom use a felony Gov. Brad Little signed the measure on Transgender Day of Visibility as advocates rallied outside the statehouse.

And in horrifying news, Idaho's governor has signed the felony bathroom ban, with 5 year penalties for second offense bathroom usage, into law.

This is the most significant criminalization of trans people to date.

On trans day of visibility no less.

It will require a new "Do not travel" warning.

1. Idaho has passed the most extreme anti-trans law in the nation, a bathroom ban. The second offense would be 5 years in jail, and the 4th offense could lead to life in prison due to Idaho's 3 strikes law.

It now heads to Governor Brad Little's desk.
