High fructose corn syrup (HFCS) is everywhere—salad dressings, catsup, carbonated beverages. Fructose is sweeter, per unit mass, than cane sugar (sucrose), and apparently keeps better, so is a favored sweetener by the food industry. Unlike glucose, fructose in converted to free fatty acid in the liver and thus can contribute to hyperlipidemia, diabetes and heart […]
I was married by the time I started graduate school. I suspect that being in a committed relationship, and in particular with someone who was also a grad student, kept me centered during the stressful times. Perhaps these were different times, but a recent study shows that today’s PhD students are struggling with mental health […]
The recurring bleat of vaccine denialists is that COVID should be addressed through “herd immunity.” Well, OK, a vaccinated population has herd immunity, but that’s not what they mean. They mean herd immunity in the sense of the Black Plague—the people who didn’t die were immune. Apart from all the deaths caused by COVID infections […]
I just finished reading “The Achilles Trap: Saddam Hussein, the C.I.A., and the Origins of America’s Invasion of Iraq” by Steve Coll. By the onset of the US invasion and military occupation, I was convinced that (a) Iraq had no WMDs or active WMD programs, and (b) there was no collusion between Saddam and al […]

It is estimated that upwards of half a billion people will be displaced by flooding, fires and desertification due to global warming. But such frightening predictions are based on climate modeling. How reliable are these models? It turns out, remarkably reliable: “Climate change doubters […]

Pertussis, in particular, is a […]
Kevin Drum has a post up about the present and future of EV charging stalls in the US. As of 2023, the number was 184,000, with public charging stalls outnumbering Tesla stalls 6:1. Is that a lot or a little? Well, lots of people say that they’re holding off buying EVs because of the range, […]
You may have read about “blue zones,” certain communities that have an unusually large number of centenarians: Loma Linda in California, Okinawa in Japan, Sardinia in Italy, Nicoya in Costa Rica, and Ikaria in Greece. Since we can’t all move there, the next best thing would be to discover the key to longevity in these […]
I recently retired after working for the same employer for 37 years. My dad also worked ca. 35 years for his employer before retiring, as did my father-in-law. My sister worked for her employer for 40 years. Two of my sisters-in-law worked for their only employer for about that long. My daughter, on the other […]
Lewis Strauss, former chair of the AEC, coined the phrase “too cheap to meter” referring to the potential for nuclear power. It was a phrase I grew up hearing in Oak Ridge TN, but it never came to be, there or anywhere else. Now, the Wall Street Journal claims that day has arrived, not because […]
