“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, سلام بازهم علاقمندان علم (Over 50,000 Bay Area residents speak Persian at home. Only about 60% of Bay Area residents speak English at home.)
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
This rotating spiral galaxy, NGC 1512, is located only 30 million light-years away, and is highlighted by a core of old stars, a central ring of hot, star-forming material, and then wispy, thin spiral arms connect it to a more ring-like, star-rich region in the outskirts. This Hubble/JWST composite image showcases the stark differences between what
Herb had some technical challenges this week, so I’ll be your guest editor. It’s only been seven years since my last turn at the wheel - let’s see how this goes!
It’s been over 20 years since the Human Genome Project was “completed” - a monumental scientific achievement marking the successful sequencing of the entire human genetic code. This groundbreaking milestone ushered in a new era of genomic discovery that continues to revolutionize healthcare and scientific research to this day. One story caught my eye about the history and legacy of that work. In an incredible invest
