I would have needed that this morning while biking and being nearly hit by a Tesla whose driver was eating a croissant rather than holding the wheel!

tired: defensive walking

wired: offensive walking

photo of a white car driving on a road. obscuring the car is a service pole with a sign on it that says: "BE SEEN - GRAB A BRICK! 1. GRAB 2. LOOK 3. WAVE 4. CROSS" the sign has an illustration of a person holding a brick and standing in a confident pose. beneath the sign, there is a yellow basket full of bricks mounted on the service pole

Your regular reminder that measles vaccines are the most lifesaving childhood vaccine in the schedule, and save over a million lives globally per year.

Measles vaccines save millions of lives each year

Measles once killed millions every year. Vaccines changed this, preventing disease, long-term immune damage, and deadly outbreaks.

People are shortsighted. All the physical infrastructures would be cheaper and a better investment if we had invented and created them. Same for everything else we are going to spend money on in the next decade.

Massive investment in science in the upcoming Canadian budget would send a strong message that rationality and reason should lead the world, not charlatanism. People will return to science-based policies and health measures, and countries that have not given up will have a strong economic lead!

We have a manuscript that looks at something like what you are referring to, specifically for oligomeric proteins. www.biorxiv.org/content/10.1...

Paralog interference preserves genetic redundancy

Models of gene duplication often assume that loss-of-function mutations neutrally promote the return to the ancestral singleton state. They thus ignore the potential functional interference between du...

This is something we are working on!

Yep. Adaptation to antifungal drug treatment. It would probably be the same in the other direction, though. Flux through enzymes can change several-fold by coding mutations, rarely so with minor changes in protein abundance.

Really excited to share our latest paper led by @simonaube.bsky.social. Fascinating results examining whether regulatory mutations can lead to adaptation as fast as coding mutations do. #mevosky #evobio #evoSky

Adaptation is less accessible through mutations in promoters than in coding sequences when large effect sizes are needed

Mutations within promoters and coding sequences are both involved in adaptation, but their relative contributions remain to be compared directly. Using the fungal enzyme cytosine deaminase, we examine...

Doug Ford is barking up the wrong tree with a ban on animal research. Nobody likes the idea of cute little puppies being killed. But populist pandering to emotion is anti-science rhetoric that serves no one, by @picardonhealth.bsky.social www.theglobeandmail.com/opinion/arti... @theglobeandmail.com

Opinion: Doug Ford is barking up the wrong tree with his ban on animal research

The Ontario Premier’s populist pandering in the wake of a report over beagles used in research is knee-jerk, anti-science rhetoric

Issues with a plasmid. The coding sequence optimized for one species works fine but not the one optimized for another (no expression here, just construction in E. coli). The company also had trouble synthesizing this particular one.

This is what I meant. I think we agree. Biochemistry does not care how alleles are transmitted.

1

Christian Landry @christianlandry.bsky.social · Sep 2

About transmission, not about biochemistry no?

Christian Landry @christianlandry.bsky.social · Sep 1

The major difference is during transmission. You can’t transmit alleles from the same locus together, but from different loci yes.
