Fast females, slow males: accelerated ageing and reproductive senescence in Drosophila melanogaster females across diverse social environments
Abstract. Females and males typically differ in lifespan, patterns of ageing, and reproduction. General explanations for variation in the magnitude of this

Happy to share the results of a long-haul post-doc project, now online @science.org, aiming at understanding the rules of transgeneration epigenetic inheritance over TEs in plants and its extent and impact in nature. More below!

Transposable elements are vectors of recurrent transgenerational epigenetic inheritance
DNA methylation loss at transposable elements (TEs) can affect neighboring genes and be epigenetically inherited in plants, yet the determinants and significance of this additional system of inheritan...

Are humans really the only rational animals? Our NEW PAPER 🎉 out in @science.org suggests otherwise! In a large collaboration led with my joint first author @hanna-schleihauf.bsky.social, we show that “Chimpanzees rationally revise their beliefs” 🧵
Chimpanzees rationally revise their beliefs
The selective revision of beliefs in light of new evidence has been considered one of the hallmarks of human-level rationality. However, tests of this ability in other species are lacking. We examined...

My awesome grad student Shashank and I wrote this paper trying to look at broader patterns of HT in TEs. HT is happening everywhere! DNA transposons jump further than other classes! www.biorxiv.org/content/10.1...
Recent horizontal transfer of transposable elements in Drosophila
Transposable elements (TEs) are genetic elements also known as "jumping genes" that increase their copy numbers within a host through various mechanisms of transposition. TEs can also move between spe...

Evidence from 14 research funding programmes confirms that early winners tend to keep winning (Matthew effect). But the idea that an early setback makes you stronger later doesn’t replicate widely.
buff.ly/UEtcRd4
eLife Assessment This important study reports the results of efforts to replicate two phenomena of significant interest to early-career scientists and scientific policymakers: the Matthew effect and the early-career setback effect. Several previous studies of these effects have focused on early-career researchers with grant proposals that fell just below or just above a funding threshold. Those just above the threshold were more likely to be successful when they applied for funding later in the career (an example of the well-known Matthew effect), while those just below were more likely to go on to have stronger publication records (the early-career setback effect). In this study the Matthew effect was found to be robust across funders, and to generalize from those close to the funding threshold to the whole population. The early-career setback effect was not robust across funders and did not generalize to the whole population. The evidence reported is convincing.
