Here, we critically review the structures of the mitochondrial pyruvate carrier (MPC) in apo and ligand-bound states, highlighting controversies with regard to the orientation in the inner membrane, interpretation of the transport states, and modelling of the inhibitors. doi.org/10.1016/j.ti...

Recently, I saw a sun dog next to the cupola of Trinity Hall, Cambridge. It is a natural phenomena where hexagonal ice crystals in the sky deflect the sun light at a 22 degree angle. They function as a prism, like diamond dust, separating out the different wavelengths. Big shout out to Newton!

A brilliant new paper by @Marilia Meira Dias and @Thomas MacVicar and others is out! It has discovered that a mitochondrial carrier SLC25A45 is involved in the uptake of methylated lysine and arginine, a key step in carnitine biosynthesis! www.sciencedirect.com/science/arti...

SLC25A45 is required for mitochondrial uptake of methylated amino acids and de novo carnitine biosynthesis
Methylated amino acids accumulate upon the degradation of methylated proteins and are implicated in diverse metabolic and signaling pathways. Disturbe…

A harder form of diamond that has eluded scientists for decades can now be synthesised in the laboratory, and could be used to make extremely tough cutting and drilling tools.

While academic publishing may not be broken, it isn’t built to serve science either. It runs on a chain of perverse incentives, but everything we need to rebuild it is already in our hands. #OpenScience #AcademicSky buff.ly/oSesI1s
Screenshot of article summary of: Toward Science-Led Publishing by Damian Pattinson, George Currie published as an opinion piece, in Learned Publishing Summary The current dynamic of scholarly publishing prioritises the wants of the publishing industry over the needs of the research community. This article explores this theme through the lens of ‘publisher-led science’ as a description of our current status quo, and through ‘science-led publishing’ as an improved future state. We argue that financial motivations central to most publishing distort how research is presented, how it is assessed and even what research is undertaken, leading to a system that hinders, rather than facilitates, scientific progress. We propose three elements of a science-led publishing approach that would accelerate research communication, incentivise collaboration between authors, editors and reviewers, and create a more transparent and equitable research landscape. We believe that research funding and research assessment are two of the primary levers for wider change in research and research culture and consider the future purpose of scholarly publishing in a world where these proposals have been widely adopted.

Proposed pH-dependent mechanism of the mitochondrial pyruvate carrier. In the outward-open state, positively charged K49 and H86 bind pyruvate, initiating conformational changes to the inward-open state. The high matrix pH deprotonates H86, allowing pyruvate to leave. www.science.org/doi/10.1126/...

It is believed that proton conductance by the mitochondrial uncoupling protein (UCP1) is inhibited specifically by purine nucleotides, but we show that pyrimidine nucleotides also inhibit UCP1 with similar affinities in a pH-dependent manner. #mitochondria www.embopress.org/doi/full/10....

Using 33 pathogenic variants of citrin we identify crucial elements of the carrier domain required for transport and show that the N-terminal domain is not involved in calcium regulation of transport, but causes a mitochondrial import defect, when mutated. www.sciencedirect.com/science/arti...
