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.

two years ago we had a mom and 2 black bear cubs hang in our yard for a whole day --here is MOM with the 2 cubs in our tree branch...could not believe it held their weight! they were after apples ..it was unreal 🤣

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?

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."

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.

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

"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.

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.
