Sadly, you’re giving them too much credit. I do not think this is about eugenics. I think this is about dimensions, by which I mean bra size, waist size, and hip size.

Sharks get cancer. People claiming otherwise are trying to sell something to the desperate. And even if sharks didn’t get cancer, eating shark wouldn’t cure your cancer any more than eating LeBron James would make you better at basketball.

I fully agree that the Taco Bell “pile on” is bananas. #hattip to Taco Bell for being quick to respond to the issue. That said I’m not sure I’m ready to put the $40B Yum! Brands (the American fast-food corporation that also owns KFC, Pizza Hut, and The Habit Burger Grill) on a pedestal.

Hold fast, Dr., to your beliefs. Racism and hatred are perennial; they always blossom in time. Eradicating racism might be impossible but your words and actions inspire us to stifle it, crush it, and uproot it at every chance.

There is nothing more humiliating than walking up with a stiff knee, barely able to walk, because you injured yourself while sleeping. SLEEPING. Theres no dignity in having to explain to people that you’ll be hobbling for the next 3 days because you slept with your legs 4° off center.

Want to learn more about our oyster research? Check out Dr. Andrea Unzueta Martinez talking on @wbur.org On Point with Megna Chakrabarti! This is an excellent episode that focuses on pollution in the Chesapeake bay. You can hear Andrea at ~33 minutes. Enjoy! www.wbur.org/onpoint/2026...

Will a historic sewage spill undo the Chesapeake Bay's restoration?
The oyster is a huge part of coastal culture and economy in the U.S. But a historic sewage spill and climate change could put decades of restoration efforts at risk.

Please spread the word! Only three more days to sign up! Join me and other sea monst-orians in exploring sea monsters in literature, film, and more. We also earn about the creatures of the deep (spoiler: They're not monsters) See link below. I hope to see you there! bit.ly/SummerSeaMon...

“He piled upon the whale's white hump the sum of all the general rage and hate felt by his whole race ...; and then, as if his chest had been a mortar, he burst his hot heart's shell upon it.” - Herman Melville Explore Melville and more "sea monsters" with me this summer. bit.ly/Summermonsters

Terrified of sea monsters? Sea monster curious? Sea monster obsessed?! There’s **five days left** to sign up for my Harvard “Summer School” sea monsters course where we explore mythical sea monsters and also meet real creatures of the deep. I would love to see you there! bit.ly/Summermonsters

It is wondrous to think that, at this very moment, there’s a pod of whales somewhere moving gracefully through the sea, feeding and napping and playing as they see fit … And not one of them is wearing a MAGA hat.

This is a guess from a pynco grad student: “It does look quite large. One lab did produce a paper saying Colossendeis species are nonbrooders, so it is probably a Nymphon (which there are species that are known to brood after the eggs hatch).

This. A thousand times this. Christy wants asked me to guess which women politicians from recent history might stand a chance at the presidency. None. Well, maybe just maybe Madeleine Albright, although she was in eligible.

Look what I found on my iPhone. In the midst of the pandemic, I paid good money out-of-pocket to have this British goat show up and spend 10 minutes with us on a ZOOM call. Ozymandias, kids of kids! Am I nuts to pay for a goat to show up on ZOOM? Probably. Would I do it again? Hell yes. #goats

Losing 3 F-15Es to friendly fire is unsettling, but you might imagine the pilots were not expecting to be shot at. Losing an F-15E to Iranian enemy fire leaves me wanting more info. The F-15E is touted as an air superiority fighter so was this ground fire? Are they more vulnerable than we are told?
