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!

Our review on the peculiar properties of mitochondrial carriers of the SLC25 family out: portlandpress.com/biochemj/art...

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.

Our review on Current Understanding of Pathogenic Mechanisms and Disease Models of Citrin Deficiency is out! The disease is caused by the dysfunction or absence of the mitochondrial aspartate/glutamate carrier 2, also known as citrin doi.org/10.1002/jimd... #mitochondria

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
