Delighted that our most recent work exploring how perchlorate salts influence vitrification and the low temprature limit for life is now out in @CommsBio!

Excited to share my latest preprint just in time for #FEMS2025 ! This preprint is the start of a series of work I've been doing trying to understand the biophysical limits to life in extreme environments. So come have a chat at FEMS if you're interested in extremophile biophysics

I am thrilled to share the first paper published from my PhD! This paper explores the growth and physiology of a bacteria in ammonia with implications for the habitability of ammonia-water environments on Earth and icy moons such as Enceladus.

Donald Trump was elected by Americans to defend the interests of Americans.
The question we, as Europeans, must ask ourselves is, are we ready to defend the interests of Europeans?

This work was conducted in collaboration between myself, @CharlesCockell, and Fernanda Fonseca @INRAE_TRANSFORM. I'll write a summary blog soon, but there's much more already in the works, hopefully ready to share at #EANA2024
Great time last week down at @DiamondLightSou with @LiamJPerera and @CharlesCockell looking at cold perchlorate solutions!

Well done to Mazin Nasralla for his paper published in @PNASNews
TMAO depletes urea in a peptide solvation shell
Combining neutron diffraction and modelling to uncover molecular mechanisms important for the physics of life.
pnas.org/doi/abs/10.1073/pna…
ALT Representative solvation structures drawn from the structural refinement modeling of the diffraction data that pertain to the peptide in aqueous urea (A) and aqueous urea–TMAO (B and C). (A) shows the urea-rich surface of GPG tripeptide in aqueous urea. (B) shows the surface of a GPG tripeptide that is now relatively depleted in urea, in a solution of aqueous urea–TMAO, and (C) shows the bulk-solution further surrounding the GPG interface of the structure in (B) in aqueous urea–TMAO. The arrow marks a TMAO molecule entrapping urea in a hydrogen bond network. Urea and TMAO molecules are colored green and purple throughout, while water molecules are described by a wire form which has been hidden in (C) to aid visualization.
