we’re gonna have figure panels that double as codons at this rate
Wow this is a seriously serious supplementary figure from @cellpress.bsky.social today. Panels A through UU.

I get that Cell likes to minimize the number of supplementary figures. But is this really what is happening here?

My heart breaks for every student and community across our nation. A fresh pain, an old wound.

Yes, here. Yes, our community. Yes, Brown. Yes, this tragic, preventable horror happened again.

We can prevent gun violence. We chose not to.

I sometimes teach in Providence. In the classroom where I most frequently teach, there's a section labeled for where students are supposed to go for active shooters. It is a cliche of a phrase, but I want to echo the Professor here and say: it does not have to be this way.
AS A PROFESSOR, I AM ASKING

HOW ARE OUR STUDENTS SUPPOSED TO LEARN IN THESE CONDITIONS?

HOW ARE THEY SUPPOSED TO GO TO SCHOOL AND TAKE EXAMS KNOWING SOMEONE MIGHT JUST SHOW UP WITH AN EASY TO ACQUIRE AUTOMATIC WEAPON?

HOW??????????
Longer statement from Brown University:

"We are very sorry to share that we have confirmed reports of multiple shooting victims, but we are not able to share their condition. They have been transported to local hospitals."

There’s an urgent need for blood in the aftermath of the Brown University shooting

If you can give, please do

If you can’t, please spread the word

Its terrifying to think how bad this shooting might be if they need an urgent call for blood, but the more people donating the more lives we can save
I am a student at Brown in communication with a friend at RIBC.

There is an urgent need for blood donations to support RI. Donations in NY, NJ, MN, NB, DE or NJ can help supply RI.

Spread the word.

Check your eligibility to donate blood, learn about the process and why blood matters, and enroll in a RIBC Donor Loyalty Rewards programs.

These aren't pedestrians, it shouldn't be legal for them to be on a sidewalk. Governments have got to start cracking down on this stuff. Heavy fines on any company that tries to pull this kind of thing.
Just as you thought food delivery companies couldn't inflict any more misery on society:

Instead of using lowly-paid gig economy contractors to deliver groceries, they're replacing humans with robots, who, in turn, force humans off the pavement into road traffic.

I want to finally do a video on sidewalk plows and the problem of leaving snowy sidewalks to homeowners.

If anyone has examples of poorly cleared sidewalks that I can use, attach them here!

Important: mention the city. Also, preferred attribution (if any). Otherwise, default is screen name.

From 2022-23 I built a dataset using news stories of 2000+ times Canadian drivers crashed into people and structures. It prompted lots of questions, which I want to answer through a series of blog posts.

My first post outlines the data and some of those questions.

A bad day for Canada, and therefore the world.

Ontario (population 16 million, 40% of the country) has passed new legislation prohibiting bike lanes that take a lane from cars.

An escalation from Bill 212, which required municipalities to get approval.
A sad day for cyclists. Bill 60 - which prohibits the conversion of motor vehicle lanes to bike lanes (or any other prescribed purpose) - has passed Third Reading this morning which will kill various cycling projects in Toronto & across Ontario. #shame #BikeTO #BikeSky #TOpoli #ONpoli #VisionZero

hell, when the first leg of the REM opened up me and my friends took it to DIX30 just because! and it was fun!
Lots of people on Reddit were in disbelief about all the positive REM videos, thinking it was a CDPQ conspiracy.

No, people really do like transit that much. You just don’t follow it when it happens in other cities.

And on top of that, the REM really is a particularly exciting project!

We could fix a lot of problems if it didn’t cost scientists $10k+ to publish open access articles and if people didn’t run into paywalls whenever they wanted to read medical or scientific research (that their taxes already paid for)
What is the most profitable industry in the world, this side of the law? Not oil, not IT, not pharma.

It's *scientific publishing*.

We call this the Drain of Scientific Publishing.
