What are freshly hatched salmon called? Alevins! Cassidy Cooper photographed these tiny fish in their early life stage. 🐟📷

Field Frame Friday: Salmon Alevins
These tiny fish, only a few days old, are newly hatched salmon. They still have their yolk sacs (bright orange in this photo) and are called “alevins.”

It's #NationalIceCreamDay!

Discover how science shapes the smooth, creamy texture of ice cream in this infographic: www.compoundchem.com/2015/07/14/i...

#ChemSky 🧪
Infographic on the chemistry of ice cream. Ice cream is formed from fats, proteins and emulsifiers, which in combination stabilise air bubbles in ice cream. Small crystals are needed for smooth ice cream, and air makes up 30-50% of ice cream's volume. A range of flavouring compounds are used. Stabilisers, often extracted from seaweed, are added in small amounts to reduce the rate of melting.

What's Earth made of? The latest edition of #PeriodicGraphics in @cenmag.bsky.social journeys to the centre of Earth to look at the elements and minerals that make up our planet's different layers: cen.acs.org/physical-che...

#ChemSky 🧪
Infographic on the composition of Earth. Scientists determine the composition of Earth by analysing surface rocks and inferring the density and composition of deeper layers from how seismic waves move through Earth. Oxygen is the most abundant element in the crust. Mafic rocks, rich in magnesium and iron, dominate oceanic crust. Felsic rocks, higher in silicates, are the most abundant in continental crust. The mantle is composed mainly of magnesium-rich silicate minerals, such as olivine and pyroxene. The lower mantle contains less magnesium than the upper mantle. Earth's outer core is liquid, while the inner core is solid. Both layers consist mainly of an iron-nickel alloy with lighter element impurities. The core’s exact composition is still unknown. Molten iron stirring in the outer core drives Earth's magnetic field.

TLDR: The eradication of screwworm from the US was super important for US livestock. A tiny US facility in Panama drops sterile screwworms from planes to prevent the spread of fertile screwworms

Why maintain a barrier zone in Panama?
Mexico border - BIG!
Panama isthmus - SMALL!

For decades, @ucdavis.bsky.social stood tall among the world's giants in agricultural research. That progress is now at risk amid threats to federal research funding (via @reuters.com) www.reuters.com/world/us/tru...
Insight: Trump funding freeze upends agricultural research at US universities
From its earliest days in 1906, when the University of California secured a small stretch of fertile soil in the state's Central Valley, a quiet promise took root - that this place, originally called University Farm, would someday grow mighty.

scottwiener.bsky.social Senator Scott Wiener @scottwiener.bsky.social · Apr 10
They’re destroying federal science capacity & California needs to step up & expand science capacity at the state level.

I introduced SB 829 to create the California Institute for Scientific Research & authorize the State of California to produce vaccines. It just passed the Senate Health Committee.

Taking time to enjoy spring flowers… thinking about my grandma 🩷 who lived thru political violence, left loved ones at ~40 yrs old for the US w/ 7 kids (#8 born here), lost her only son in a motorcycle crash, etc… she was a gardener and in dark times always said “apples will grow again” 🍎🌸

Erika Cheung spoke with Nature about working at Theranos and how blowing the whistle on the company and Elizabeth Holmes changed her career. “I’m still in shock how much this derailed my life.” 🧪

Listen this IS in fact how it’s done.

Georgetown Law Dean William Treanor responds to Acting U.S. Atty Ed Martin’s threat to refuse to hire Georgetown graduates who have taken “DEI” courses in their curriculum.

Treanor is a brilliant lawyer & constitutional scholar. Embarrassing for Martin.

I really feel for the early career researchers impacted by what’s happening in the US. It’s hard enough for them to complete a PhD and build a career. This has long term implications for research capacity globally.

There are so many reasons to be sad/angry etc about what is happening to science in the US, and this is one: Postdocs and PhD students hit hard by Trump’s crackdown on science www.nature.com/articles/d41...

Within the span of 90 minutes on Tuesday morning, two airplanes, at Washington’s Ronald Reagan National Airport and at Chicago’s Midway International Airport, were forced to abort landings to avoid collisions, federal aviation officials said.
Two Planes, in Washington and Chicago, Abort Landings to Avoid Collisions
The near misses on Tuesday came after a string of aviation disasters, including the midair collision between an Army helicopter and a passenger jet last month that killed 67 people.
