Our first paper on algal experiments at NIG with @yawaguchi.bsky.social! We found that a single episode of sexual reproduction can produce large variation in population growth rates (and prevent extinction) under dual stressors @jevbio.bsky.social doi.org/10.1093/jeb/... bsky.app/profile/bior...

1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social.

What's the prettiest wrong idea in all of 20th century science? Francis Crick famously developed a "comma-free" genetic code, where frameshifts don't change the sequence. The model's elegance was that it only uses 20 of the 64 codons - the exact number of encoded amino acids!

Interesting paper!🤩
I keep finding myself suggesting this brilliant paper by John Welch, about why pointless debates in evolutionary biology + behavioural ecology. Maybe it is easiest if I just repost it here every so often?

#OTD in 1859, Charles Darwin published his book On the Origin of Species, saying ‘light will be thrown on the origin of man’. Exactly 115 years later the skeleton known as Lucy was discovered in Ethiopia!

How to write a grant?
1. The application is for the reviewer, not you, the applicant.
2. Communicate in stories.
3. Make your story cohesive—leave no puzzling gaps.
4. Make your story resonate to keep the reviewer reading.
5. Accept chance and noise in peer-review.
