AI helps unravel a cause of Alzheimer’s and identify a therapeutic candidate
A new study found that a gene recently recognized as a biomarker for Alzheimer’s disease is actually a cause of it, due to its previously unknown secondary function that triggers a pathway that disrupts how cells in the brain turn genes on and off.

Optimal Peanut Butter and Banana Sandwiches
I was personally useless for most of the Spring of 2020. There was a period of time, though, after the peak in coronavirus cases here in NYC and before the onslaught of police violence here in NYC that I managed to scrounge up the motivation to do something other than drink and maniacally refresh my Twitter feed. I…

German solar and wind are triple the cost of French nuclear, last half as long
France’s nuclear energy spending was 60% of what Germany spent on renewables. France gets about 400 Terawatt hour per year from nuclear but Germany gets 226 Terawatt-hours each year. 45 Terawatt-hours of Germany’s renewable power comes from burning biomass which generates air pollution.
