Molecular biologist from Texas, here to share my meanderings on nature, science, history, politics, and zombies. Long threads a specialty.
I have fallen in love 😍 with this preposterous birb, the American dipper or 'water ouzel' (Cinclus mexicanus).

It's North America's only AQUATIC SONGBIRD.

The bobbing makes it look like it's trying to psyche itself up to jump into the icy-waters, but watch...

Take a minute to appreciate this time lapse video of Shaggy Ink Cap mushroom fruiting (Coprinus comatus) taken by Steve Downer over the course of a few days.

The "ink" is actually a spore-filled liquid created by 'deliquescence': liquefaction of their own tissues by autolytic enzymes.

There are TWO crystals of bismuth here.

One is an oxidized "hopper crystal", so named because it resembles pyramidal "hoppers" with open spaces in the middle. It's probably lab-made by repeated heating & cooling cycles.

The other is a solid unoxidized cube of bismuth metal.

Climbing a tree to escape a bear is a plan with only one really fatal flaw:

Bears ascend trees with incredible speed, owing to a number of adaptations to their musculoskeletal system that make them exceptional climbers.

The early microbiologists called these "sun-animalcules" for the shape, which became 'Heliozoa.'

The long thin projections are 'axopodia.' They're like sticky, retracting arms that pull food items in (Ochromonas algae in this case?)

I just think they're neat. 😀🦠🔆

Let's talk about the aircraft carriers of the animal world, the Common Loon (Gavia immer), native to Canada & the northern US.

The chicks are born precocial, meaning they can swim moments after hatching, but hitch a ride on a parent for two reasons...

Franzi Schimmer captured this Grizzly bear in Brooks Falls, Alaska just floating along, tippy-tapping down the river, browsing the salmon.

Prior to hibernation, up to 40% of a bear's body mass is fat, which is less dense than water (~0.9 g/cm^2), so the murder-monster is also a floaty-boaty.

What I love about ichthyosaurs: they're marine REPTILES pretending to be fish pretending to be dolphins.

Like, if you unfocus your eyes here, it's a dolphin, right?

But I think we need to talk about Ichthyotitan: a marine reptile pretending to be a fish pretending to be a BLUE WHALE.

You're gazing into the baby blues of a conch, a medium to large sea snail. I THINK this species is a Queen conch (Aliger gigas), common in the Caribbean.

The true conchs (Family Strombidae) have camera-type eyes with hemispherical lenses, some of the most complex eyes in gastropods.

As I get ready for another cozy weekend of Olympics watching, I'm seeing lots of chatter about ice quality for different sports. As a Minnesotan and a science journalist, just wanted to reshare this video about why ice temps matter!
It turns out that not all ice is created equal. Ice rinks are calibrated specifically for different sports, and at the Olympics these sport specifics are tightly controlled by the event’s "ice meisters."

This strange little bird is an 'oystercatcher', one of 12 species in family Haematopodidae, Latin for "blood foot" because of dark red coloration on the legs of some.

A group of them is called a "stew".😀

Let's talk about the utter weirdness of their eyes & beaks.

The tech behind 'Pop Rocks' candy was patented in 1961, but the product wasn't launched until 1976.

They're created by putting a super-saturated solution of sugar (sucrose) in a chamber pressurized with CO2 to 50 atmospheres (730 psi).

Gas-filled bubbles form, then are captured in the crystals.

Hello world. One of my favorite fun facts to share about elephants…their trunks are covered in whiskers, with built-in intelligence! If that got your attention…check out our new paper in @science.org www.science.org/doi/10.1126/...

Modern alligators & crocodiles are basically the Corgi or Dachshund version of their early ancestors, "pseudosuchian archosaurs".

Early crocodylomorphs were much smaller, but had long legs & may have been partially bipedal: running on all fours, but capable of climbing and snatching with forelimbs.
a warm welcome to galahadosuchus, a small crocodylomorph from late triassic england 🐊 the holotype was previously referred to terrestrisuchus, but bodenham et al. redescribe it as a separate taxon in their #openacess paper

TIL:
"Paprika" is a spice made from ground red pepper, first cultivated in Mexico.

The term is the diminutive of 'papar', Hungarian for 'pepper'. It was introduced there from the New World ~1560's.

Heat level is mostly determined by how many seeds are mixed with pericarp.

Why don't Texans put beans in chili?

To answer that, I have to tell you some of the *clear history* & *hazy legends* of chili con carne, the 'Chili Queens' & San Antonio.

The story (might) start on the Canary Islands 1731, claimed by Spain, but off the coast of Africa. A group of 16 families...

1895: Lyman Davis of Corsicana, TX sold chili from the back of his wagon for 5 cents. He made enough to buy a store where he sold "brick chili" to oil boomers.

In 1921, he started canning it and selling it under a brand named for his pet wolf, Kaiser Bill (shown)

Thus, Wolf Brand Chili was born.

It's NOT true that Darwin owned an unread copy of Mendel's work Versuche über Pflanzenhybriden ("Experiments on Plant Hybridization").

He owned an uncut copy of Die Pflanzen-Mischlinge ("The Plant Hybrids") by Focke, which SUMMARIZED Mendel's findings.

Mendel, however, DID read Darwin's work.
What I think is fascinating is that Darwin went to his grave not knowing what the mechanism for heredity was and ruing that he was missing a fundamental part of his theory… and someone found a copy of Mendel’s book, unread, in his library.

A letter from Charles Darwin to Charles Lyell on Oct. 1, 1861:

"But I am very poorly today and very stupid and hate everybody and everything."

then, later: "One lives only to make blunders."

So relatable.
