In this episode of the Epigenetics Podcast, we caught up with Melissa Harrison from the University of Wisconsin-Madison to talk about her work on the “Pioneer” Transcription Factors - Zelda and Grainyhead - and their role at the maternal-to-zygotic transition.

It’s important to put these numbers into context.

Flu positivity is at or around the peak levels we saw in recent pre-pandemic years.

As we’ve seen in the news, hospitals are already stretched and covid and flu are adding even more pressure.

In a year of high excess deaths, the excess deaths in the week ending 23rd December are the highest yet, with almost 3000 excess deaths compared to the 2015-2019 average (not age-adjusted).

This is 26% higher than the average

It’s hard to link definitively to the causes, but…

As you might have read today, #Adobe is doing really bad stuff (https://toot.cafe/@baldur/109630505660962387).

Fortunately there are many projects you can follow on here which are providing free open source alternatives:

➡️ @darktable - Photo software which lets you organise, view and develop raw image files

➡️ @Krita - Professional digital painting & 2D animation app

➡️ @kdenlive - NLE video editing software

➡️ @inkscape - Vector illustration software

➡️ @Blender@mastodon.social & @blender@video.blender.org - 3D animation and special effects

2022 ended with a shiver, but the start of 2023 broke a sweat. 🥶🥵

This weather whiplash may have been caused by changes in the polar vortex, the band of strong westerly winds over the Arctic. Details: https://go.nasa.gov/3XaD4iK

Consequences of using journals as a measure of scientific value:

During Reinstein's career "roughly half of what [researchers casually] talked about was...the actual theory, methods, and results?

No, we talk about who got into which journal and how unfair it is, which journal should we be submitting our papers to [...] how highly rated are these journals,"

Researchers waste "a tremendous amount of time 'gaming'" the system.

Happy to announce this pub, which is the culmination of last 10 years of my career beginning as far back as my MSc🎓
We find that #antimicrobialpeptides are evolved to control specific #microbiome bacteria. This example is a textbook case of host #immune #evolution being shaped by the microbiome 🦠

Cellular heterochronicity

"Neurons with longer timescales show higher response selectivity for temporally extended computations such as decision making and reward integration, whereas shorter timescale neurons are implicated in sensory processing."
