He emerged and then retreated back to the interior. He was not a groundhog, and his retreat does not suggest we will have 6 more weeks of winter. Jared Isaacson and fellow Pola
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 what?” It is the lowly penny.

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

“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

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.

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.
