Have you ever wondered ๐ค... Does phenotypic variance respond to environmental perturbation? Does it have a genetic basis? Are mean and variance regulating loci exposed to different selection pressures? These and more questions are explored in our new preprint ๐ฅ

Beyond Mendel: a call to revisit the genotypeโphenotype map through new experimental paradigms
Abstract. The long-standing notion that genotypes map to phenotypes through simple one geneโone trait relationships continues to shape both research in the
New Perspective!๐ฅIt's fascinating how scientists from different fields but interested in the same question [e.g. genotype-phenoytpe relationship] can have such different perspectives. Here we put in our 2 cents wrt genetic effects being context-dependent, and pheno variation being mostly polygenic

For starters, there's not "one weird trick to ditch your X." There are multiple paths to sex determination turnover.
To read more about it, including what genes were gained or lost and how the genome looks in X chromosome scales, check out our preprint:

A small polymerase ribozyme that can synthesize itself and its complementary strand
The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...
How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?
Excited to share our latest work in @science.org on a new small polymerase.

For once an article about the "how to get to Rome" and not "Rome" itself. Collaboration with my "partner-in-crime" @felibas.bsky.social has been a key ingredient of my research over the years. Sara Miller at Molecular Cell spoke with us of how we got there and what we think about collaborations.

A member of the Hymenoptera order, Colletes cunicularius, has an evolutionarily conserved sex-determination mechanism.
CREDIT: NJ Vereecken
A sex-determining gene region in ants, bees, and wasps has maintained its function for over 150 million years through its chromosomal position rather than its DNA sequence, as evidenced by the lack of sequence homology among lineages. In PNAS: https://ow.ly/n9eU50XWipU

Great new paper!
Many stinging wasps, bees, and ants have controlled the sex of their developing eggs for millions of year using an ancient segment of their genome- always the same segment- but what's weird is, *the exact DNA sequence of that segment doesn't seem to matter*.

Specialized signaling centers direct cell fate and spatial organization in a mesodermal organoid model
Stem cellโderived mesodermal organoids reveal how signaling centers guide cell fate and tissue organization.

How do new centromeres evolve while staying compatible with the division machinery?
Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Defensive fungal symbiosis on insect hindlegs
Dinidorid stinkbugs were reported to possess a conspicuous tympanal organ on female hindlegs. In this study, we show that this organ is specialized to retain microbial symbionts rather than to perceiv...
"When the female bugs lay their eggs, they rub the cultivated hyphae across the egg mass. The hyphae grow to envelope the eggs and physically exclude attentive parasitoid wasps until the bugs hatch."
