So cool!
To make the 3D animations I used UCSF Chimera, a free molecular modeling program. When scientists discover a new protein structure they upload it to the worldwide Protein Data Bank. Each entry is assigned a unique ID number, which you can use to call up the structure in programs like Chimera or PyMol.

Jade and striped icebergs. “When seawater at depths of more than 1,200 feet freezes to the underside of massive ice shelves like East Antarctica’s Amery Ice Shelf, it forms ‘marine ice.’ Enormous hunks of ice calve—or break off—from the ice shelf, creating icebergs. When one of these icebergs overturns, its jade underside is revealed. The wondrous color of this ‘marine ice’ results from organic matter dissolved in the seawater at those great depths,” explained Audubon Magazine. “Green icebergs are infrequently seen because their verdant bellies are underwater; it’s only when they flip over, a rare event, that their richly colored regions can be seen before they melt. Striped icebergs, perhaps even more scarce than jade bergs, are thought to form in one of two ways: either meltwater refreezes in crevasses formed atop glaciers before they calve icebergs (creating blue stripes), or seawater freezes inside cracks beneath ice shelves (creating green stripes).”

My FAVORITE THING is researchers who wholeheartedly embrace the Ms. Frizzle aesthetic and wear their field of study on their literal sleeve. Everyone in the invasive crayfish consortium has tiny lobster-print shorts or socks. All the middle-aged dad scientists here at the lab have shirts with fish and/or fishing tackle patterns on them. My moss specimen and ammonite earrings keep getting noticed by women who are wearing silver fishbone-shaped or native plant-themed earrings themselves. Every single person on the outreach team has at least one shirt with an anchor pattern on it from Old Navy, and almost all the younger researchers have tattoos featuring their research interests – one fisheries biologist has a half-sleeve of native species she literally uses as an outreach tool. We are self-aware and having a blast with it, honestly.
Not to start any political discourse but I’m REALLY gay 🌿🍄
