Be ungovernable, like birds who make nests OUT OF ANTI-BIRD SPIKES. A new study describes resourceful Dutch & Belgian corvids besting evil architecture by stealing metal anti-bird strips and using them like thorny twigs, to construct their homes.

Like thorns, the spikes may protect their nests from predators.

Lead author Auke-Florian Hiemstra wrote an epic 🧵 about his research that's worth a read: https://twitter.com/AukeFlorian/status/1678703433900064773

Paper: https://www.hetnatuurhistorisch.nl/organisatie/publicaties/deinsea/deinsea-21/

A bird's nest in a tree in Antwerp. The nest is made of metal anti-bird spikes.

@laminda That's so metal!

@laminda European corvids are one up on Australian sulfur crested cockatoos who were ripping anti-bird spikes off a building and chucking them at people https://www.theguardian.com/environment/2019/jul/05/chick-flick-cockatoo-gives-anti-nesting-spikes-the-bird-in-viral-video

@Sheril @elisegravel I've always told people not know but wanting to know always made me a better meteorologist.

@Sheril @elisegravel Very cool. Also, scientists will never tell you "This [whatever] is absolute truth" but rather "From what we know thus far..." such and such. Science is in continuous evolution the same way we never stop learning (if we try). No wonder fanatics hate it.

iamcanehdian,

Accurate. The resurgence of a disease we got rid of lays squarely on the shoulders of idiots.

The UK bungled covid response just like the US did, and the NHS is under attack by people trying to wreck it so it can be privatized-- so you're not far behind us. There will always be people nervous about vaccines, but the problem gets magnified when healthcare institutions aren't trustworthy.

@violetmadder @cmsdengl @iamcanehdian our problems with antivaxxers started long before covid. We have struggled with MMR uptake since at least Andrew Wakefield.

T Also captured were unusual cloud ripples above the pileus cloud. The formation of a rare pileus cloud capping a common cumulus cloud is an indication that the lower cloud is expanding upward and might well develop into a storm. Credit: Jiaqi Sun

The winners of this year's "Small World" micro-photo competition are out. I'm especially intrigued by this astonishing shot: a struck match, caught at the exact moment of ignition.
(It ended up in second place, go figure.)

Born in 1906, computer scientist Grace Hopper invented the first compiler for computer programming language & was among the first programmers of the Harvard Mk1 computer.

Hopper popularized the idea of machine-independent programming languages & paved the way to develop COBOL (an early high-level programming language). She originated the term "bug" to describe computer glitches & became a celebrated Rear Admiral in the US Navy.

@Sheril a family member went to a lecture of hers

She handed out "nanoseconds" -- pieces of a particular wire gauge that were 12.5 inches long. Signals would traverse them in one nanosecond

Really a great visual aid for many reasons, both then and now

This is not correct. The Earth has been known to be round since Classical times, and this has always been accepted by mainstream Christianity.

timglauert,

@SKV @Sheril
No need to apologise, it is a very common misconception. It is used by Flat Earthers to erroneously claim that the Catholic Church once supported Flat Earth.

In 1916, 23 yr old chemist Alice Ball discovered a breakthrough in treatment for Leprosy (Hansen’s Disease). She was the 1st woman & 1st Black chemistry professor at UHawaii.

Tragically, Ball passed away months after her discovery due to complications from a lab accident.

What happened next? Arthur Dean, head of her dept, continued the work publishing Ball’s process as “Dean’s method.”

Fortunately, a colleague spoke up & the name was changed to “Ball’s method.”

@Sheril I want to know more about this "lab accident" given that Dean subsequently grabbed credit for her work. If only Hercule Poirot had been available to investigate. 😉

@wjmaggos @dangillmor What I've done is go to: https://fediscience.org/public/local and also https://fediscience.org/public and just looked at who's posting, find interesting people, and follow them. I wasn't able to access an instance Directory (some instances allow this), but this is working for me so far! I just check in periodically, and then I try to remember to put them all on my science list.

@Sheril @lisamelton out of respect for this absolute legend, I shall nobly resist the urge to make any rear admiral jokes.

There should be statues of Grace Hopper in every major city, her life should be the subject of textbooks and movies. She was a total bad ass, perhaps one of the most important people to ever live.

Born in 1910, Dorothy Crowfoot Hodgkin perfected X-ray crystallography, a type of imaging using X-rays to determine a molecule’s three-dimensional structure.

She determined the structures of insulin, penicillin & vitamin B12, leading to tremendous advances in medicine.

Hodgkin was awarded a Nobel Prize in Chemistry in 1964. She also advocated for world peace, campaigning against both the Vietnam War & nuclear weapons. https://www.nobelprize.org/womenwhochangedscience/stories/dorothy-hodgkin

Today I learned the word ‘scientist’ was coined in 1834 to describe Mary Somerville, replacing the term ‘man of science’.

@absolutspacegrl she was also a pretty epic advocate for women’s education. For some reason (some) men seem threatened by how awesome she was.

Evolution doesn’t look how it’s depicted in pop culture. We often picture the famous “March of Progress” illustration where a series of apes stand in line leading to a modern human.

But evolution is not linear. It branches & divides without an intended direction or endpoint through natural selection.

Physicist Lise Meitner’s brilliance led to the discovery of nuclear fission. But her long time collaborator Otto Hahn, was awarded the Nobel Prize in Chemistry without her in 1944, even though she had given the first theoretical explanation.

Albert Einstein called Meitner “our Marie Curie." She also adamantly refused to work on the atomic bomb during WWII. https://whyy.org/articles/lise-meitner-the-forgotten-woman-of-nuclear-physics-who-deserved-a-nobel-prize/

@Sheril Meitner's Nobel snub was terrible on so many levels.

For everyone who doesn't pay attention to the periodic table, she did get an element named after her (https://en.wikipedia.org/wiki/Meitnerium), though only after her death.

Shocking story about mRNA pioneer/Nobel winner Katalin Karikó, whose early advisor at Temple tried to have her deported & derailed her career because she dared to look for a better-paying job.

Later, UPenn demoted her, then forced her out, because her research wasn't bringing in enough funding. [HT Paul Novosad]

coreyspowell,
@coreyspowell@mastodon.social avatar

The story about Katalin Karikó's early career comes from the new book "A Shot to Save the World" by Gregory Zuckerman.

In interviews, Katalin Karikó remarkably expresses no bitterness about her experiences. Just a clear focus on the goal of using mRNA to treat human disease. https://www.pnas.org/doi/10.1073/pnas.2119757118
