Massively parallel characterization of transcriptional regulatory elements - Nature
Lentivirus-based reporter assays for 680,000 regulatory sequences from three cell lines coupled to machine-learning models lead to insights into the grammar of cis-regulatory elements.

Can we look at ways to make the road network profitable? How about turning every road into a toll road for drivers?

1. Imagine we land a space probe on one of Jupiters’ moons, take up a sample of material, and find it is full of organic molecules. How can we tell whether those molecules are just randomly assembled goo or the outcome of some evolutionary process taking place there? 🧪

As someone who has been working extensively with PyTorch Ledidi: this effort is noticed and very much appreciated. I hope to have the ability eventually to contribute improvements back to the community.

If we could put cycling in a pill, it would be the blockbuster drug to end all blockbuster drugs. (I'm also surprised that the mortality improvements for pedestrians seem much smaller than for cyclists.)

A Scottish study of 83k individuals over 17 years found commuting by bike halves the risk of early death: bmjpublichealth.bmj.com/content/2/1/.... The one outlier hazard ratio for people on bikes casts a harsh light on the Ford government's quest to destroy safe infrastructure in Toronto. #BikeTO

Yes -- I think this is just a temporary issue caused by their server infrastructure being overloaded. The developers have done an impressive job of scaling up with the massive influx of new users, so this will probably be resolved soon.

Following the 2013 floods that destroyed parts of that system, I had to move the first few km of that trip to suburban roads. A couple months later, while riding that part, a driver hit me intentionally with his truck. I've been radicalized ever since.

I grew up in Calgary. I became passionate about cycling when I started commuting to U of C on a Raleigh Record I got for $15 on Craiglist. It was a 58 km round trip with only 500 m not on the pathway system, and significantly faster than Calgary Transit.

The rhetoric around "we're destroying cycling infrastructure so you can get home to your family faster" is a wonderful reminder that people on bikes don't have families, and that your life stops mattering as soon as you get on a bike.

A pair of graphs I think about a lot. On the topic of pooled CRISPR screens, the left is "replicate correlation" when simply examining the abundance of guide RNAs, i.e. log-normalized read counts. On the right is taking those same data and subtracting from a common starting point, i.e. pDNA.

I lost four teeth in that incident, had to go through four surgeries over the five years subsequent to resolve the damage, and will be dealing with the dental complications for the rest of my life, including today's root canal. The timing for the reading is wonderfully ironic.

I'm writing this from my dentist's office, where I'm getting a root canal necessary because of the driver ten years ago who intentionally used his vehicle as a weapon against me when I had the temerity to be cycling on a road without a bike lane, necessitating we share the road.

Our premier in Ontario is planning this for January right before the next provincial election. Our premier in Alberta did this 20 years ago. Standard conservative playbook: dismantle the government, bribe people with their own money, win popular acclaim.
