(1) Today's story was the destruction caused by Hurricane Ian in Florida. It is one of the strongest hurricanes ever to strike Florida, and in the coming days, we will learn more about the damage and victims.

🧵 Beginning of a thread

(2) Expect lots of shocking photos and heartbreaking videos on social media that will remind us of the power of nature, specifically when boosted by the additional energy we have trapped in the system.

(3) Man-made climate change has raised sea levels and warmed the oceans, which fueled Ian to a hurricane that, at a certain point, was just two mph shy of a Category 5.

Mais quel est ce grave problème qui préoccupait les scribes Égyptiens à l’époque de Thalès, c’est-à-dire vers -600 ? Famine ? Épidémie ? Pénurie d’huile d’olive ?
Je vous donne un indice : c’est en lien avec la grande pyramide de Khéops à Gizeh. 👉 Image
La réponse se trouvera dans « Eurêka » !
Eurêka est le premier tome de la série Épistémè, qui racontera l’histoire des idées scientifiques (ou épistémologie) de la Grèce antique au XXe siècle.
Épistémè est réalisé sur une idée et d’après les textes de Pascal Marchand, chercheur à l’université Toulouse 3 Paul Sabatier.…

So there are a few things that I want to cover today. It has to do with #Cuba🇨🇺 & the new #FamilyCodeLaw #CodigoDeLasFamilias #CodigoSi & why the Extreme Right Wing of the #CubanDissidents & #CubanExiles are against it #LGBTQRightsAreHumanRights #CubanConstitution #Socialism
So first what is #ElCodigoDeLasFamilias Or the #FamilyCodeInCuba. First we need a small lesson in #Socialism. #Marxism teaches that we need to use #Science & Common Sense to advance society.
Common sense says if you want a #Democracy to advance and flourish, you need to improve it with scientific precision. So, #Marxist countries make it very easy to have what is known in America as a #ConstitutionalConvention. Aka whenever they come up with something better for

⚡Aeroelastic Flutter⚡

The Tacoma Narrows bridge disaster of 1940 attribute the collapse of the bridge due to aeroelastic flutter.

1️⃣ Flutter is a dangerous phenomenon encountered in flexible structures subjected to aerodynamic forces. Flutter occurs as a result of interactions between aerodynamics, stiffness, and inertial forces on a structure.
2️⃣ In an aircraft, as the speed of the wind increases, there may be a point at which the structural damping is insufficient to damp out the motions which are increasing due to aerodynamic energy being added to the structure.

Die beste Strategie hilft nicht, wenn der Mensch nicht mitmacht. Das hören wir u.a. bei #Corona oft. Es zieht sich aber ja durch alle großen Themen und Diskussionen. Mein Lieblingsthema #Science sind deswegen aktuell Normen & Werte & ihr Einfluss auf Verhalten. Ein Beispiel 🧵
Am Thema Lastenräder. Gerade wenn man auf die Verkaufszahlen schaut ein ziemlicher Boom. Gerade läuft in Hannover auch die "Nationale Radlogistik Konferenz". Woran scheitert eine breitere Nutzung von (Lasten-)Rädern. Das ist spannend. 2/
Denn wer hätte bei dem Thema direkt daran gedacht, dass auch die Ansprüche an unseren Kleidungs- und Stylingsstil & "Look" damit zusammen hängen? Sogar am Ende ein sehr einflussreicher Faktor sein können? Wieso fahren nicht mehr Menschen (Lasten)rad? 3/

This is a thread about how anyone can use publicly accessible sequence databases and free software to discover new things about #genomes, #biology, and life on earth.

#Bioinformatics #Genomics #Evolution #Science #MolecularBiology #DNA #Research #DataScience #LifeSciences Image
Genomes are absolutely loaded with complex information, most of which we still don’t understand.

Complete and near complete genome sequences are now available for many organisms.

However, decoding the information in these genomes remains a slow and difficult process. Image
A large proportion of most published genome sequences consist of DNA that is incompletely understood in terms of its evolutionary origins and functional significance. Image

#bced Pro-D. The chair gave me time to explain what this thing was , humming in the middle of our circle of 27 mostly unmasked teachers. I said it was a #science project. We had #wildfires which gave us choking smoke....1/ #covid19bc #CorsiRosenthalBox
...It was built by the #science class. I shared that the #CorsiRosenthalBox can breath in >1000x more air than our lungs so any wildfire smoke, pollution or airborne diseases like flu, or covid is more likely to be caught here before we breathe it in! #bced After I presented 2/
after I presented, a teacher took a pic of it & asked me how to make it. I promised her a link to how to make a #CorsiRosenthalBox so she could make one with her child.

#GratitudeThread as I was enjoying a to-go meal from an Asian-fusion restaurant in Soho, it occurred to me that #WildGinger had made it. The third year of the pandemic, and they are still sending out delicious dishes. So thank you to all the small businesses which survived.
Thank you to the healthcare workers who have endured years of pandemic patients, pushed to their limits in surge after surge, with more on the horizon. People who care for people are the best people. Grateful to all of you who who do this work.
Thank you to the teachers who had to power through the pandemic adjusting their lesson plans to present them remotely, and now return to the classroom with little real protection in place. Teaching is a calling. And to the school support, staff, also offering gratitude.

"#Imitation vs #Innovation: Large #Language and Image Models as Cultural #Technologies"

Today's Seminar by SFI External Prof @AlisonGopnik (@UCBerkeley)

Streaming now:

Follow our 🧵 for live coverage.
"Today you hear people talking about 'AN #AI' or 'THE AI.' Even 15 years ago we would not have heard this; we just heard 'AI.'"
@AlisonGopnik on the history of thought on the #intelligence (or lack thereof) of #simulacra, linked to the convincing foolery of "double-talk artists":
"We should think about these large #AI models as cultural technologies: tools that allow one generation of humans to learn from another & do this repeatedly over a long period of time. What are some examples?"

@AlisonGopnik suggests a continuity between #GPT3 & language itself:

Tonight I'm scheduled to fly 12 hours to NIH for some muscle imaging, a blood draw & a skin biopsy. It's a small followup study to their intramural ME/CFS research looking at muscle energetics. Ridiculous travel for a small amount of research but it's for #science.
And just so you don't think I'm too altruistic, I also get to see some dear friends.
First stop at NIH Bldg 10 (the Clinical Center) - the aquarium at patient admissions where I said hi to this yellowbar angelfish. Image

Pre-print alert 🚨 New story from my lab "The cytidine deaminase APOBEC3G drives cancer mutagenesis and clonal evolution in bladder cancer" This is one of the first projects in my lab, so I am thrilled to see it come to fruition 🐁🧪 🔬 #bladdercancer #biology @OncoAlert
We previously showed that bladder cancer is characterized by extensive and early divergent evolution.
We also showed that the APOBEC3-like mutational signatures were enriched in chemotherapy-resistant urothelial cancers… @NatureGenet

« Très estimée Madame Curie,

Ne vous moquez pas de moi si je vous écris sans avoir rien de sensé à dire. Mais je suis tellement enragé de la bassesse avec laquelle le public ose actuellement s’occuper de vous qu’il faut absolument que je donne libre cours à ce sentiment.
Cependant, je suis convaincu que vous méprisez constamment cette populace, qu’elle vous prodigue obséquieusement le respect ou qu’elle tente d’assouvir sa soif de sensationnalisme !

Je suis obligé de vous dire à quel point j’admire votre intelligence,
votre dynamisme et votre honnêteté, et que je me considère chanceux d’avoir fait votre connaissance personnelle à Bruxelles. Quiconque ne compte pas parmi ces reptiles est certainement heureux, aujourd’hui comme autrefois, que nous ayons parmi nous des personnages tels que vous,

8 Mäuse (in Worten acht 🐁) haben die amerikanische FDA im Juni so beeindruckt, dass sie bei @pfizer_de @biontech den neuen BA 4/5 #impfstoff gegen #Omicron bestellt haben. Das geht hervor aus der Präsentation des Herstellers (s.u. N=8)
Bis heute hat der Hersteller zum BA 4/5-Impfstoff nur Tierdaten abgeliefert und die auch nicht öffentlich, sodass unklar bleibt, ob zu den 8 🐁 noch weitere 🐹🐹oder möglicherweise eine durchimpfte Tierhandlung hinzu gekommen ist
Die Bestellung beläuft sich auf 170 Millionen Dollar, die unklare Datenlage kritisiert sogar #Science in seiner aktuellen Ausgabe

We at @weatherindia are celebrating 600% growth in monthly web traffic at the end of 50 months of editorial operations.

Along the way, we saw many ups & downs! We learnt critical lessons about digital media, science writing & weather forecasting in India.

Here's a compilation👇
Four years ago, @timesbridge joined hands with @IBM to make weather & science news popular in India with the theme #MausamIsAwesome! Initially, we assumed our audience was very niche & planned to grab their attention with detailed, expertly curated features.

Alas, we were wrong!
Appetite for #ScienceWriting was no longer limited to an ‘urban-elite India’, and instead of long commentaries, readers craved quick, actionable insights!
But mainstream media had limited space for sciency content, leaving a huge void. We were quick to recognise this gap!

#SecteT [Thread]
Critique du genre VS #transactivisme

Ce thread pour désembrouiller les esprits, suite à la polémique liée à la campagne du #PlanningFamilial parlant sérieusement d’« homme enceint » 🫃🏽
Pour commencer, mon intervention à @SudRadio avec @Garcia1Laurence (1/2) 👇
#SecteT 2
Nul besoin de l’extrême droite pour affirmer qu’il y a 2 SEXES, et – contrairement à ce qu’en dirait l’extrême droite – qu’ils ne doivent en rien obéir à un GENRE. L’émancipation du genre est un combat de gauche, or, c’est précisément contre elle que se bat la #SecteT
#SecteT 3
2 sexes : mâle, femelle – la réalité biologique humaine. Mais s’il nous est impossible de nous en affranchir, nous pouvons en revanche nous affranchir des stéréotypes sexistes de genre qui leur sont traditionnellement associés. #MontyPython <3…

Alright, gonna try sharing some of my visual strategies + tips for visually communicating science on a more regular basis.

🧵 Let's start off with figure labelling. And let's use this image from a paper I just read as an example:

#science #biology #scicomm #vizscicomm #datacomm Image
First - I love the stippling illustrations. This is a nice technique that offers good contrast between structures.

The labelling, however, is a serious impediment to the eye. Subconsciously, our brains are trying to break this down + are taxed with making sense of this info🧠⚡️ Image
When we visually communicate technical images, we need to be mindful of how the eye travels, what information it's picking apart, and how we can alleviate any strain or taxation that may interfere with - and disrupt - our ability to absorb new information. Image

¡Regresaron los hilos! 🧵

Hablemos de la CONTAMINACIÓN de objetos caseros con el virus de la #ViruelaSímica 🐒

Se encontró material genético del virus en superficies 20 días después de iniciado el confinamiento de 2 pacientes, a pesar de realizar limpieza 

¿Pánico o no?

Hace unos días la @CDCgov dió a conocer los resultados de un estudio de superficies contaminadas en la casa de dos personas en Utah que, luego de un viaje, dieron positivo para viruela símica¹

La presentación de la enfermedad fue moderada y se resolvió en 30 días o menos

Para evaluar la presencia del #virus y el grado de contaminación de los objetos, se pidió a los #pacientes que señalaran los objetos y superficies con los que tenían más contacto 🖐🏼🪥

Se tomaron muestras de 30 superficies usando hisopos

Do you know why we're seeing all those bios on 'far-right politics, extremism, etc' lately? It's all publication bias. I left my professorship long enough ago that I can recount a little anecdote.
I wrote three, near-identical survey experiments on support for 'extremism & terrorism': one on the right, one on Muslims, one on the left. Right-wing one was accepted at the second journal I sent it to, with some minor (stylistic, formatting) revisions required.
Islamism one was rejected 4 times before it finally got a very lengthy R&R, which I withdrew from consideration because satisfying the reviewers would have (incorrectly) changed the conclusion.

It's a season of lab rotations for PhD students!! Students - Go to every lab with a broad, open outlook, interact & learn. Think about which topic drives the passion in you, see which lab environment you would fit best into! #AcademicTwitter #AcademicChatter
There are many factors to carefully ponder upon before you choose & make your decision. Think it through as grad school forms the basis & foundation of your career in science be it academia, industry, other allied careers!
#science #sciencetwitter
You spend a significant amount of time of the peak of your career in grad school in the lab hence choosing the right lab & the research that you are most passionate and driven about becomes highly important!

The solar flare coming made me make this graph. It represend cold matter falling down, mixing with rising red matter and finally escaping the suns gravity. It led me to some interesting insights, especially when combined with another graph I made yesterday!
One of the conclusions is that there are more reds rising to support blues, then there are reds actually escaping. That means the mass below slowly becomes bigger, as the sun cools and becomes denser reactivating its core until the situation reverses.
This reaction oscillates every 15 years, and every 300 years if I remember correctly. Thats an effect of all those layers having different "seasons" that take multiple of the others seasons before they change themselves. When it summer for all of them, the sun spews.

A 🧵regarding the news of the CDC’s new guidelines:

In no particular order…:

I was not allowed to volunteer at my kids’ schools for over a year because I wasn’t vaccinated.
A family refused to carpool with us because they said they were “uncomfortable” with their son sharing a car with us. We had been ratted out by a mutual friend who said to the other mom “well, you do know they aren’t vaccinated, right?”. (Trust, shattered)
We were uninvited by good friends to share a vacation house with them; a long standing tradition was ended over medical choice. They all got Covid anyway, of course.

My daughter couldn’t attend a theater production with her school’s theater company because @DenverCenter rules.

In #football #Analytics we often refer to the analysis of attacks as sequence analysis, implying an attack can be modeled as a cascading sequence of events. A thread on why the term “sequence analysis” can be misleading.

#DataScience #Research
Despite the popular analogy (often used to describe strategic moves), #football is actually nothing like a game of chess. In chess, one piece can be moved at a time, after which the opponent reacts. In #football, 22 pieces can be moved simultaneously.
The movements of the 22 pieces are strongly bound together, and #Science has shown that attacking play is not the result of individual, sequential, actions, but rather the product of inter-player & inter-team interaction.
