Paleoecology, taphonomy, sed/strat, marine biology, mass extinction ... all things Earth history. Doomed to repeat it whether we learn from it or not. Living in the past and talking to dead things since the late Holocene.

One of the things I appreciate about Egyptian mythology is the accountability and empiricism in their approach to the afterlife. No last minute confessions, appeals to the gods, or blanket forgiveness ... just a simple, standardized test.

I am given to understand it's International Day of Women and Girls in Science 🧪. There are many who deserve recognition, today and all days, but there's one I have to pay tribute to: Dr. Karin D. Rodland, whose PhD in rodent metabolism evolved into a career in proteomics and cancer biology.

I wish someone would run the control group for the Great American AI Bubble experiment:
Investing billions into a diverse group of STEM researchers, humanities scholars, and creatives of sorts to prove or disprove whether datacenters can actually compete.

#MolluskMonday means moar mollusks, so here's a small selection of a large collection of unionid bivalves (a diverse clade of freshwater mussels) collected by my predecessor, Jack Kovach, in 1969. I estimated around 1500 specimens in Jack's drawers (wait) when they got transferred to Cincinnati. ⚒️🧪🦪

I think one of the best things that happened to me, academically, was hitting this stage in middle school, when the "talented and gifted" kids all got tracked into the same classes together.
The challenge level stepped up when we were young and sorting out social skills, and,
We found our people.

I think a reasonably frequent experience for junior academics is a life wherein they were the smartest person in the room in most rooms they were in (even some pretty fancy rooms) up until The Great Filtration suddenly puts them among a bunch of other people with the same life experience.

I hate what K12 education did to the thought processes of generations (myself included).
My career was endlessly convincing science gen ed students to trust their first thought, to apply Occam's Razor and run with a hypothesis until it didn't work anymore.

the small % of students that do end up engaging with me end up saying 'Thanks, this was very helpful, I understand this better now!' –– yes, this is in fact my job, I'm not here to trick you

Velociraptors had feathers
‘HOPE IS THE THING WITH FEATHERS,’ EMILY DICKINSON
famously wrote, and that often leads to pictures of doves sitting quietly and looking sweet, but what if hope is an albatross that can soar for years without stopping, or an osprey that can haul a thrashing salmon out of rough waters?

#FossilFriday falls with the creeping inevitability of a global glaciation. These Proterozoic stromatolites from Minnesota's Iron Ranges stand as a reminder that, no matter how small we are alone, together we can change the world, making complex relationships possible like a breath of fresh air. 🧪⚒️

While I tend to identify more with paleontology, I was always the faculty member assigned to teach sed/strat. So, let's take a look at some sedimentary structures associated with the Sturtian glaciation! ⚒️🧪🧊

So, that's my backyard this morning. The rhodies are very temperature sensitive: that vertical droop curled into tubes corresponds to lical temperatures around 0°F.

Dragonfish (family Stomiidae) are cunning predators. Although they are strong swimmers, they prefer to lie in wait and ambush unsuspecting fishes and crustaceans. This black dragonfish (Idiacanthus sp.) was spotted at 527 meters (1,729 feet) in Monterey Bay.

Really SVP? You’re just going to ignore decades of sexual and academic misconduct, marrying a student AT one of your conferences, and every report I’ve filed (implying that’s what you do with reports) to defend famous Horner? You’d rather have pedophiles than students is your message?

Only 10-20% more? I'm honestly surprised. Expected worse.
Here’s what they found:
Women are interrupted more often than men—by about 10–20% in economics seminars.
Those interruptions are more likely to:
- Cut women off mid-sentence
- Come from men
- Be adversarial rather than clarifying in nature
