- Reposted by Mark HuisingE-bikes are an amazing transportation tool. Especially in urban places. We should make them more accessible along with building safe bike infrastructure. Go after the illegal bikes/electric motorcycles and don't forget about those cars that actually kill almost 40,000 Americans a year.

- Reposted by Mark HuisingIn October, ICE grabbed Maher Tarabishi. He was a 24/7 caregiver for his disabled son Wael. At the time of Maher’s detention, disability advocates warned that taking away Wael’s caregiver put his life at risk. Wael died on Friday at age 30. ICE caused his death. They didn’t get to say goodbye.

- Very proud to see the main thesis work of the intrepid Dr. Mohammad Pourhosseinzadeh come out in @pnas.org today! In this paper, Mohammad assesses how crosstalk between insulin-secreting beta and somatostatin-secreting delta cells in the islet actually happens, in near real-time. A quick thread 1/10
- We have known for a long time that insulin secretion from pancreatic beta cells and somatostatin secretion from their neighboring delta cells is synchronized and therefore coordinated. Our question was how this coordination is achieved. 2/10
- Based on optogenetic experiments, it had been suggested that beta cells and delta cells are connected via gap junctions of similar conductance as those between beta cells. Here we show that it is a little more complicated, and interesting. 3/10
-
View full threadUnderstanding these mechanisms of local crosstalk matters, because they break down quickly in diabetes. This failure to communicate between islet cell types makes diabetes worse. 10/10
- Reposted by Mark HuisingYeah man they ain’t coming back. This is going to be one of the biggest foreign policy blunders of my lifetime, and it’s entirely possible that some guy at ICE ordered it not having any clue what he was doing. This is why we used to leave foreign affairs to sensitive nerds.

- Why can't CA do as NY just did and ban fossil gas in new buildings. I electrified in a retrofit and my energy bills went down, plus it is more comfortable, pleasant and healthy to breathe indoor. We can and should build quickly AND energy efficiently. We should be ditching FFs at every opportunity.
