New research alert! In 2019, Museum researchers David Gruber and John Sparks were diving in the icy waters surrounding Greenland when they discovered that the variegated snailfish (Liparis gibbus) glows. This tiny snailfish remains the only polar fish reported to biofluoresce. Now, in a recently published study, they have uncovered something else surprising: this fish contains the highest expression of antifreeze proteins ever observed. It also sends up a red flag about how these highly specialized animals might fare in warming environmental conditions. Read more about their findings with the link in our bio!

Several US agencies, including the National Oceanic and Atmospheric Administration (NOAA) and the Department of Energy (DOE), will see a significant influx of cash from a massive climate and tax bill that US President Joe Biden signed on 16 August. Scientists around the world welcome the legislation, called the Inflation Reduction Act, which pledges US$369 billion in climate investments over the next decade — while acknowledging that more work is needed to counter global warming.
The legislation would cut US greenhouse-gas emissions by about 30–40% below 2005 levels by 2030, scientists estimate, bringing the country closer to delivering on its pledge of a 50% reduction, which Biden made last year. And it signals to other nations that the United States, a major emitter that has historically pumped the largest share of greenhouse gases into Earth’s atmosphere, is on board to address climate change, scientists say.
After former president Donald Trump took steps away from climate action, “it returns the US to a position of leadership”, says Michael Mann, a climate scientist at the University of Pennsylvania in Philadelphia. “It helps create a global climate for action.”

Snailfish With Anti-Freeze In It's Veins Found Beneath Greenland Iceberg
A snailfish (Liparis gibbus) with the "highest expressions levels" of bioluminescent green anti-freeze proteins in its veins has been found by scientists drilling into an iceberg off Greenland.
The anti-freeze proteins work the same way that anti-freeze in cars works. It regulates the temperature of the organism . How, you say? Well, the proteins stick to the surface of ice crystals and slow them, preventing them for growing larger. Fish, unlike other cold blooded organisms, cannot survive when bodily fluids freeze, so grains of ice form in their cells, freezing them from the inside out. The anti-freeze stops this.
Even more extraordinary than the snailfish's ability to produce the anti-freeze, it exhibits biofluorescence (the ability to convert blue light into green, red, or yellow light, typically used during extended periods of darkness, like those at the poles). This characteristic is normally found in fish swimming in warmer waters, and this is the first reported case of an arctic fish species displaying it.
However, due to warming water temperatures caused by climate change, warmer water species can migrate further north now, creating more competition for the snailfish, making it's anti-freeze proteins slightly unnecessary.
This extraordinary little creature certainly has provided us with some food for thought about how organisms adapt to their environments.

Good luck to everyone who has results coming up, wishing you all the best !
This post features a book I've read recently- CERN and the Higgs Boson by James Gillies. It was a really interesting read, and I enjoyed learning about both the history of CERN and the discipline of particle physics as a whole. The book felt a bit repetitive at times but I've also had far too much fun making myself a timeline of particle physics history lol so overall a book I would recommend :)

day 005/??? of studyblr stuff
CRYO TIME! the tweezers get so cold…
helical reconstruction keeps on going, and I played catan for the first time (and the second time, and the third, and lost terribly every time).
I also watched all of glow and didn’t start my machine learning final until way too late, and boy am I paying for it. sigh. note to self: at least make a plan before you put something off so you make an informed bad decision.

Shoutout to all the queer folk in STEM. I doubt this is news to anyone but there's always a lot about theatre gays™ or how 'all' queer people's favourite subject at school was English. Here's to all the gays who CAN do maths, to all the queer scientists. I love been a queer in stem!

Fun Fact: Oilbirds are Basically BatBirds!
I want to talk about these amazing birds:
Tumblr media
I love them. I mean, look at their big, shiny eyes! NO ONE can say that they aren’t cute as hell!
The other reason I love these animals is because they’re basically what happens when evolution tries to make a bat out of a bird.
These little guys are known as oilbirds (Steatornis caripensis), and are also called guácharo (and also several other things, because they are found in South America, plus Trinidad & Tobago, which all have INCREDIBLE language diversity). 
Oilbirds are nocturnal, flying around the forests of South America at night looking for fruit to eat. They also live colonially in caves, which they navigate using echolocation.
So, to review:
Tumblr media
(I’m making my Generic Bats a very generic fruit bat, for the record).
Oilbirds are the only birds with this combination of traits, which I think is pretty cool of them! Why are they so much like bats? Basically, when different types of animals evolve under similar selective pressures, they often evolve the same features! This is called convergent evolution, and wow I talk about it a lot on this blog! It turns out that nocturnal animals that live in caves and eat fruit can sometimes benefit from traits like these!
Tumblr media
(they’re, like... spooky-cute. Cute-spooky? Either way, I like them a lot)
So, if these birds are flying around at night, how do they stop themselves from flying into things while searching for that tasty, tasty fruit?
Well, in the forest, they mostly rely on their AMAZING night vision (which is another trait they share with bats, fyi). That is why they have such big, adorable eyes, which has a lot of light-sensing cells called rods. They actually hold a record for the density of the rods in their eyes: one million per square millimetre. That is the highest density of any known vertebrate. It’s about 6x denser than the rods found in human eyes! 
Tumblr media
...still cute
Their amazing vision allows them to see very well in low light, which is how they navigate the South American jungles at night, searching for food under the moon and stars. That said, their vision just doesn’t cut it when it comes to flying in the caves they call home. Why? Well, caves are dark as hell, and even the best night-vision can’t do anything for you when there’s no light at all. Plus, flying into cave walls/ cliff faces hurts, so it’s good to be extra sure you’re not flying into solid rock!
So how do they find their way around these dark caves? Well, they use something very unusual for birds: echolocation!
Oilbirds are one of only a few species of birds that are known to use echolocation (the others are a few species of  the closely-related swiflets (Collocaliini), but I HAVE DECIDED TODAY IS FOR THE OILBIRDS im sorry, swiflets, ilu2).
Tumblr media
Look at them, not flying into rocks! I’m so proud (˃̣̣̥ ◡ ˂̣̣̥)
Also, a bonus fact, because idk where to fit this but I MUST mention it:
They have little whiskers around their beaks (which are technically called “rictal bristles”, but I’m going to call them “whiskers” because I like that word better). These whiskers are basically used to feel things that they have in and around their mouth, helping them find, manipulate, and eat their tasty fruit!
Tumblr media
...moustache...
This has been Fun Fact Friday!

Within a diamond hauled from deep beneath Earth's surface, scientists have discovered the first example of a never-before-seen mineral.
Named davemaoite after prominent geophysicist Ho-kwang (Dave) Mao, the mineral is the first example of a high-pressure calcium silicate perovskite (CaSiO3) found on Earth. Another form of CaSiO3, known as wollastonite, is commonly found across the globe, but davemaoite has a crystalline structure that forms only under high pressure and high temperatures in Earth's mantle, the mainly solid layer of Earth trapped between the outer core and the crust.
Davemaoite has long been expected to be an abundant and geochemically important mineral in Earth's mantle. But scientists have never found any direct evidence of its existence because it breaks down into other minerals when it moves toward the surface and pressure decreases. However, analysis of a diamond from Botswana, which formed in the mantle around 410 miles (660 kilometers) below Earth's surface, has revealed a sample of intact davemaoite trapped inside. As a result, the International Mineralogical Association has now confirmed davemaoite as a new mineral.
