Out now in @PLOSBiology, @Kelley__Harris and I try to unravel what altmetrics and the fire hose of social media data really tell us about the potential impacts of research papers. 1/n…
First, some background. Academics are *obsessed* with impact. Our entire ecosystem—grants, tenure, publications, etc.—is built around generating new & striking knowledge, with an implicit goal of producing immediate economic, environmental, or cultural impacts. 2/n
Impact is remarkably difficult to measure, and even harder to predict. Remember 2017 Nobel winner Jeffrey Hall? He left academia a decade prior, in part because the impact of his work was not immediately appreciated by funders and publishers. 3/n…

1/ Those who follow me know that I think too much and ask too many questions. In my curiosity, I recently stumbled upon a story of a bat cave of coronaviruses, sudden unexplained death, and mysterious poison mushrooms🍄 Buckle up it’s a weird one #medhistory #SARS #Covid_19 🧵👇 Image
2/ It all started with that foolish preprint that was again claiming that SARS-CoV-2 was made in a lab. A claim that no respected scientist or clinician supports, given the lack of evidence, including: @K_G_Andersen @AngieRasmussen @CT_Bergstrom #COVID19

3/ So, I go back to what evidence we actually have. Because #science is awesome, we have a ridiculous amount of viral genomes that have continued to be tracked from early on in the pandemic:
- 4,678 @nextstrain @TrevorBedford
- 84,932 @CovidGenomicsUK…

On not expecting your trainees to be in perfect mental health, a thread:
I debated disclosing my grades, but because science twitter is so into toxic, over-achiever culture, I'm gonna do it. It's not like I'll ever get into a PhD program so what the hell. I also worry about someone on twitter getting pissed and weaponizing this, but the only
time we seem to talk about grades is to humble-brag. "LoL I oNlY gOt FoUr As ThIs SeMesTeR". So anyway, here are mine, and they're very much a reflection of how I was doing each semester, good or bad.

A thread on resources I find helpful for building accessibility into posters, sites, & slides: #ScienceTwitter

-Color Oracle ( Filters over your screen to approx how it would look to someone with a common color deficiency. Also has a grayscale feature.
- WebAim: Contrast Checker (…). Checks if a foreground & background color combo is readable & meets the WCAG AA/AAA standard.
- WAVE Web Accessibility Evaluation Tool ( Checks elements of HTML code against accessibility standards.
Regarding WAVE, so many websites don’t include a language in their doctype definition. That’s how screen readers determine the lang. It’s super important! If your site is multilingual, you can redefine lang for a section. There’s also a WAVE extension:

This article was published in multiple avenues and is getting a big platform. I want however to highlight that none of the authors are equity and inclusion experts. I used to be a co-author and left because our visions of what a piece like this should accomplish didn't align.
I want to give my thoughts about the article as a scholar of DEI, as someone who has worked on the field and did a PhD focused on this. So I will start with this idea of "opening up a new era of diversity, equity & inclusion"
The door to this era has been opened for a while, people are just not walking through it. I think is problematic to think we can with an article do something like that when we know historical institutions take many many years to change. And it takes the literal blood of many

Q: Why do undergraduates flounder at generating research ideas?
A: Productive curiosity is a skill that needs to be taught. My first Twitter thread! (1/11)
#PsychTwitter #AcademicChatter #AcademicTwitter #ScienceTwitter
Learning how to ask scientific questions requires familiarity with the types of questions that science is best-suited to answer. “Be curious!” and “Ask questions!” is easy for you to say, because you’re already a nerd who self-selected into an inquisitive profession. (2/11)
When we fail to instruct how to ask good questions, in their place we get speculative hunches, boring generalizations, or blank stares. Enter question coaching: you provide the structured starting questions that mimic how scientists think. (3/11)

Sometime before 1565, an enormous deposit of graphite was discovered in Cumbria, England. The locals had been using the black powder to mark their sheep.
It was discovered that this #powder could be used as a refractory #materials to line molds for cannonballs, resulting in...1
...rounder smoother balls that fired farther because of better aerodynamics. This was so valuable to the English Navy that the mine came under the strict control of Queen Elizabeth I. The poor locals and miners began to smuggle chunks of graphite out of the mine. The French...2
...among others, paid a good amount. So the locals carried this material in their pockets, making their hands and clothes black and dirty. Thus, the dark black graphite opened up a secret and illegal #market. Over time, this came to be called the 'Black Market' #ScienceTwitter

Stellar Nurseries

That is the name for regions of space filled with gas and dust and bright young stars!

Active star formation is truly a thing of beauty 😍 just look at this. What can we you in this picture?

Look closer....

📸: prawn nebula/@ESO
Apart from the (gorgeous) blue stars, there are 2 main features:

1) Very bright areas:
That's where stars have just been born! 🤩 The most massive ones are so bright that they can heat the gas up to 10,000 degrees, making it glow! 😱

2) Dark areas: they look mysterious...
But they're really not 😉

These dark regions are dense "molecular clouds", that are roughly 1000 times colder than the bright areas!

They eventually fall in on themselves under their own weight, or get squished by the powerful winds of new stars. When they get dense enough...

Lithium is the only metal to have been produced at the Big Bang. All other elements - except Hydrogen and Helium - were produced by stars - some in hot nuclear cores, others in fantastic explosions like a supernova.
The percentage of lithium in the Universe, however, is more ...
..or less the same today as it was at the beginning of time.
In other words, the lithium that powers your laptop is as old as the Universe itself! With only three protons and three electrons, lithium is a fragile element that is easily destroyed in the hot interior of stars...
The only exception to this rule is a class of Red Giant stars that are much heavier than the sun. These stars contain 1000 times more lithium than others. This result comes from a study of 200,000 stars observed with a host of large telescopes on earth and in space. These ...

Working to become anti-racist requires that we research & acknowledge the persistence & gravity of structural racism, so we've created a series of 10 infographics about why racism is a public health problem. Here's the overview:
The full series with functional hyperlinks is on our website, & we'll be posting snippets throughout the coming days!…
Here are some myths we'll be disproving around race & public health!

My day in the lab as a disabled person, a thread (feel free to RT).
I have cerebral palsy, autism (which I normally don't publicly admit), ADD and a learning disability. I'm also profoundly visually impaired. Those involved in #wormgate though it was ok to compare that joke to mocking the disabled.
This is just a form of tokenism from people who have NEVER in all their professional career, lifted so much as a finger to help this community.

Because some professors think it's ok to double down, I thought I'd do the sensible thing, and take you through my day in the lab.

Just a thought: When we discuss #COVID19 severity varying in response to the dose of viral exposure, that likely also has a temporal component. 1/?
As in, clearing a virus from the body requires a coordinated response from multiple arms of the immune system, each of which takes different amounts of time to ramp up. Early innate response is quick, but largely incapable of responding to exponential growth. 2/?
So being exposed to a large dose of virus at once could lead to a hyperreactive innate response that causes exaggerated adaptive immune responses down the line. 3/?

Dear Scientists: Is your research just?

Knowledge is power, and scientific research shapes and changes the world just as much as it describes the world. This thread is meant to help scientists reflect more critically on our own research and to mobilize science for justice. A graphic representation of this tweet with the title "
To review, Western science, which is built upon the exploitation and oppression of Black people and communities, is one part of institutionalized racism.
But we can build a more just science. B/c #ScienceIsPolitical, scientists must reflect on the values embedded in their research, and choose the systems that their research works to uphold or dismantle. How does your science perpetuate white supremacy? How does it combat racism?

Got a lot of interest in my '30 days of @MATLAB tips I wish I had known in graduate school'. So I finished writing all 30+I'm posting them here. I hope these help people imagine and be creative, earn a living, and enjoy coding. Please share #ScienceTwitter #AcademicTwitter /30
I'm also conflicted about posting coding tips today. Much STEM research goes to support surveillance, militarization, and racist state violence. So please consider what you are doing today and what it means for someone else's tomorrow. Educate yourself. s/o @HellaBlackPod /30

How do we quantify how much #virus is in a sample (titre). We use a plaque assay, which is why he most commonly used method. Below is a graphical version I've made (on @BioRender) of how it is done in the lab.

But how do they work? - a thread
#SciComm #Virology #phdchat
Here is a photo of a #SARSCoV2 assay, the virus which causes #COVID19 ( Photo: Müller/Charité). The large areas which are clear are known as plaques which are caused by virus killing cells in a monolayer. More plaques = more virus titre

#virology #sciencetwitter

2/n SARS-COV2 plaque assay
The technique was originally developed for #Bacteriophages bit was adapted by Dulbecco in 1952 for animal #viruses. Viral stocks are dilutes 10 fold in series and placed onto a monolayer. After incubation a gel is placed on the layer, restricting infection to nearby cells

What’s the difference between colon and lung? Not an easy question when it comes to #KRAS. Our work out today in @CD_AACR today describe a strategy to overcome resistance to KRAS G12C inhibition in CRC. @sloan_kettering @Albert0Bardelli @BardelliLab👇👇👇
Molecular response to KRAS G12C inhibitors is different in CRC and NSCLC models. CRC models show quick MAPK pathway rebound
Receptor tyrosine kinases and EGFR dependency is stronger in CRC models

This Plandemic video with Mitkovic makes me feel rage, bewilderment, and fear all at once. It's slick, and it's dangerous. I personally think it's important to engage laypeople about this without snark and disdain. Here's my experience #ScienceTwitter #AcademicChatter
A family member sent it to me 2 days ago and after reading up on it I started by respectfully suggesting they remember this is one side of a story, by a person that has been through some stuff and is very angry. I said in cases like this, when emotions and stakes are high..
that is exactly when you should go look for an alternate view because the truth often lies "somewhere in the middle". Maybe that was risky (not to say this is all lies) but I didn't want to lose her. I then asked, with genuine curiosity/ kindness what about this video struck her?

We found unique breast immune cells in the duct walls – ductal macrophages. They remove dying cells, help remodelling + are key players in cancer.

How did we get from this first sighting to finding their identity and function? Follow this thread!
1/n Discovery of mammary ductal macrophagesTissue-resident ductal macrophages survey the mammary epithelium and facilitate tissue remodelling
The breast contains mammary ducts surrounded by fat, blood vessels, immune + other cells.

We use 3D imaging to investigate the complex relationships b/w these cells to better understand disease.
#microscopy #mammarygland
The ducts form a tree that branches through the breast and blooms and recedes in pregnancy and weaning. These are precancerous mouse ducts, alveoli in lactation and a summary of development in mice.

Dear scientists: now would be an amazing time for you to tweet about why Black Studies and Women’s and Gender Studies (WGS) are important to you as scientists and humans. Use the hashtags #BlackStudiesMatters #WeNeedWGS! Lift up your voices for fields that make ours better!
Without Black studies and WGS, I might not know any history of Black women in science. Both fields help me make sense of my life as a scientist and have kept me in the scientific game. #BlackStudiesMatters #WeNeedWGS
#BlackStudiesMatters because it is one of the reasons I grew up believing in my own humanity, knowing I come from a community with history that runs deeper than what white supremacy likes to teach us.
