The #circadian clock & cellular #metabolism are tightly coupled. Yao Cai & @joanna-chiu.bsky.social explore a @plosbiology.org study showing how #glucose metabolism changes during the day in #Drosophila and how it is disrupted in clock & sleep mutants 🧪 Paper: plos.io/3Olm1M1 Primer: plos.io/4sUov2g
Clock-gated morning rush hour of glucose utilization depicted as highway traffic. In the morning (left), clock-controlled food intake at dawn results in high glucose concentration in Drosophila body tissues, analogous to higher number of vehicles on the highway. This increased “traffic flow”, defined by the total number of vehicles passing a given point in a given time, is aided by the opening of the “7AM-11AM only” lanes that are gated by the circadian clock. This is analogous to higher metabolic flux in the morning hours in fly tissues. In other times of the daily cycle (right), both glucose concentration (number of cars) and pathway flux (traffic flow) are low. Vehicle icons were generated by authors using Google’s Nano Banana 2 from the prompts such as “create a top-view of a car icon in white background”, February 16, 2026.

Can a single brain cell decide whether to eat or not? 🧠🪰 Turns out... yes. And we found it in the fruit fly. A pair of neurons called SELKs (subesophageal leucokinin neurons) can drive feeding behavior in both directions. They promote it or suppress it. Here's how: 🧵

eLife Assessment
This work provides one of the first important attempts to look at Drosophila immune responses against bacterial, viral, and fungal pathogens in a way that combines the roles of four major arms in immunity (Imd signaling, Toll signaling, phagocytosis, and melanization) rather than studying them separately. The findings are compelling and the tools provided can be used as they are, or built upon, in various contexts.

Moderna just received Health Canada authorization for its updated LP.8.1 variant COVID-19 vaccine.

The exciting part? It will be manufactured domestically!
Their authorization allows parts of the vaccine to be produced at Moderna’s new facility in Quebec, while the fill-finish will be handled by Novocol Pharma in Ontario. The domestically produced vaccine will be ready for this year’s fall vaccination campaign.
