Hello again Science Fans!

Did you notice a change today? Me either, but at 5:44 AM today, astronomical Autumn began in the Northern Hemisphere, the Autumnal Equinox. So happy fall.

Our calendar has gotten much more active now that schools are back in session and more seminars are on the schedules. We’re listing 94 events over the next two weeks.

Hello again Science fans!

Let’s start out with something fun, and not truly science-related. It may make you laugh, may make you mad, may make you shrug your shoulders and go “so w

CLIMATE

Above is the world’s second all-electric cargo ship. It’s 120m long, 24m wide, and has the battery capacity of a thousand Model Y Teslas (50,000,000 Wh). Like the other and smaller electric cargo ship - the Yara Birkeland - it is plying inland rivers instead of the open oceans. Ocean shipping ac

ENVIRONMENT

“You can’t always get what you want,” and you can’t always see what you want. That is thought to be why Brown Pelicans are starving in California. These prehistoric-looking birds hunt for fish near the water’s surface, then plummet ou

Hello again Science fans!

These past few years have put us all through a bit of a wringer. Prior to the pandemic, 11% of Americans reported symptoms of anxiety and depression, according to the Household Pulse Survey, a tool of the Census Bureau. Then came COVID, and that number increased to 42.6%. Today, it is down to 20.7%, but that is still almost double pre-pandemic numbers. The political climate certainly contributes to this, I’m sure. But the biggest component seems to be young adults. According to “The Morning” newsletter from the New York Times on August 8, the percentage of young adults reporting symptoms had been rising for around a decade before COVID. Uncertainty about their future, inflatio

BIOLOGY

Above is an artist’s representation of a flagellar motor that spins a bacterium’s flagella. The spinning flagella propel the bacterium through water. The colorful squiggly things represent proteins. The big wheel isn’t big. It would take 10 million of them side by side to span a single centimeter (0.4 inch). A typical rate of spin is 30,000 rpm, or 500 times a second. When you get the chance, come back here to watch this über-fascinating 23-minute vid
