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

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

Occasionally, ants get injured by predators, or from fighting, or from skate-boarding. Rather than drag around a broken, bleeding leg, an injured ant will request an amputation by another ant. Afterall, it’s p

I keep humming to myself, “Oh Lord, stuck in orbit a-again.” (With props to John Fogerty, a former El Cerrito teen) Not only is the Starliner crew - Suni Williams and Butch Wilmore - stuck in the orbiting International Space Station, none of the crew can even take a stroll outside since the ISS

The photo of a Bali beach covered in plastic waste (photo above) is in stark contrast to my mind’s eye image of the renowned Indonesian vacation paradise. If you watch TV with advertisements, you’ve probably seen colorless squashed plastic containers arise into pristine pastel plastic receptacles in an ad from America’s Plastic Makers. It is disingenuous hype f

In 1967, Roger Payne and Scott McVay discovered that sounds made by male humpback whales were complex arrangements that lasted as long as 30 minutes before being repeated. Multiple males even sang in unison. From year to year some ‘phrases’ were replaced by new ones. ¿Language? More recently we’ve learned that brain anatomy suggests whales could be capable of language. Also, t

科学迷们，大家好！(Hello again science fans!)

Neanderthals (H. neanderthalensis) and Denisovans (H. denisova ??) interbred at various times and places. (The “??” following H. denisova refers to the current situation where insufficient Denisovan fossils exist to firmly classify them.) Modern humans interbred with Neanderthals so today we H. sapiens have varying snippets of DNA derived from Denisovans. Also, study of blood types of these three groups suggest that Rh incompatibility may have affected the health of some hybrids. (By the way, D
