If all humans died, when would the last light go out?

#Science #XKCD

One of my PhD students was invited to give a talk at an international meeting (Belgium), but her visa didn't come in time and she couldn't go. It would have been a really unique opportunity for her to meet other scientists in the field, so it's frustrating that bureaucracy got in the way.

Just another reminder of how many hurdles there are for many international graduate students trying to do their work.

Henrietta “Etty” Darwin was born in 1843, the eldest of Charles Darwin’s daughters to reach adulthood.

She became a key editor of her father’s scientific writing, most notably The Descent of Man & Selection in Relation to Sex, published in 1871.

Charles Darwin considered Etty a “dear coadjutor, fellow-labourer” & lively member of an intellectually stimulating household. #science #HistoryRemix

Travis Rieder's new book, Catastrophe Ethics, "aims to advise the well-intentioned, morally anxious & philosophically curious person" confronting the questions about whether our personal choices about the environment, technology, & justice matter.

Sounds like an interesting read: #books #science #philosophy

Mesmerising microbes: bacteria as you’ve never seen it before – in pictures

As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.

Pioneering geologist & oceanographer Marie Tharp changed our understanding of the ocean.

When Tharp sought a geology job at Columbia in 1948, women couldn’t go on research ships. So she was hired to assist male grad students.

Back then, many scientists still assumed the bottom of the ocean was featureless. Tharp figured out how to use data to create sketches of the ocean floor. Her hand-drawn maps helped develop plate tectonic theory. #science #history

A nice write up of my talk this week about communicating #science

This talk is 10 years old & feels more relevant than ever #science #politics

Another mRNA #vaccine win:

Scientists have developed a cancer vaccine that can deliver treatments more effectively in people who have brain cancer and teach their immune systems to fight back. They’ve tested it successfully in four people now, and are moving on to more testing.

Born in 1894, physicist Marietta Blau’s research led to a way to capture the tracks of speeding subatomic particles.

In 1937, Blau & Hertha Wambacher made a discovery that launched the field of particle physics. But she was forced to pause her work in 1938 bc of the Nazis.

Blau was nominated several times for the Nobel Prize but never won. Cecil F. Powell later built on her work & earned the Nobel Prize in Physics. #history #science #historyremix

‘We need to slow down scientific publishing’

'We focus on metrics to evaluate a scientist’s career: how many articles they have published, how many times they were cited, what was the impact factor of all these articles. '

It’s #EarthDay & I’m giving a talk all about the global food system & its impact on the environment.

The agricultural sector is one of the most significant + immediately scalable places to have impact.

Since my talk isn’t public, here’s a great piece from @globalecoguy & the good folks at Project Drawdown.

Born in 1750, Caroline Herschel worked as assistant to her astronomer brother William. But she also made her own discoveries of nebulae, stars & 8(!) comets.

In 1787, King George III employed Caroline as her brother's assistant, including a small salary that made her one of the first women paid for their contributions to #science.

Caroline submitted over 550 stars to the existing star catalog & received honorary membership in the Royal Society. #history

Powerful eruption occurring now at Ruang volcano in Indonesia's North Sulawesi Province. Hundreds evacuated so far.

Photos show the lava flow, huge ash cloud, and volcanic lightning. #volcano #science #nature

Most members of my lab are international, and I'm often surprised at the expansive bureaucracy they have to work with just to attend some meetings or visit home.

"Citizenship privilege harms science"

"Researchers from the global south face often-distressing immigration bureaucracy that most from the global north do not"

So cool!
Great pics of new ocean species recently discovered!

Ben Barres was a trailblazing transgender neurobiologist who promoted equity & diversity.

His pioneering research on glial cells changed science & he became the 1st #trans person admitted into the National Academies of Science.

Barres was a strong advocate for women, early career scientists & the #LGBTQ+ community at a time when few people openly discussed gender identity. #history #science

Excerpt from his autobiography:

Our little show about the science behind what we eat & its impact on the planet made the ‘Championship Round’ of the local PBS ‘March Madness’ brackets…

If you have an Instagram account, this is the last time I’ll request support from the fediverse (click on the profile icon for stories)

The competition is just for fun of course, but I do love that we’ve made it this far with a family program about #science

The “History” channel 😆

I simply adore this comic by Sketching Science #science #art

When I post about #science & #history, I tend to highlight the trailblazers we don’t usually read or hear about in #HistoryRemix.

But tonight I want to share this beautifully composed piece about Nikola Tesla.

While his inventions are legendary, you may not know how Tesla’s OCD shaped his approach to science & ultimately led to his world-changing ideas. It also left him isolated & alone. But he still experienced deep connection by caring for birds.

Several kind folks have asked about my dissertation research on #science & #politics so now that I've defended, I posted the abstract at

Several of us overly online biologists spent years quietly doing an experiment on Twitter, trying to find out if tweeting about new studies from a set of mid-range journals caused an increase in later citations, compared to set of untweeted control articles.

Turns out we had no noticeable effect; the tweeted papers were cited at the same rate as the control set.

Our paper, headed by Trevor Branch, was published today in PLOS One:

Fossil stingray (Cyclobatis sp.)
Upper Cretaceous. Approximately 100.5 million to 66 million years ago. When alive, this creature lived in warm, shallow seas and had a very short tail, which was fitted with a venomous stinger. Discovered in Haqil, Byblos, Lebanon. It just happens to look like an ancient space alien. #science #fossil #archeology #evolution #photo #nature #biology #wildlife

On Friday morning, I will defend my dissertation.

The research explores how congressional staffers make #science policy decisions at the national level. I used to work in the Senate, which inspired this journey into the social sciences.

(Friday is also the first day of my kids' Spring Break, so they'll be coming along which should be interesting).

For those curious about the topic, I share a bit about the research on my substack. More results will there soon

This puppy is fully vaccinated & finally ready to make friends! Thanks #science 🐾 #dogsofmastodon

Beatrice ‘Tilly’ Shilling was born in 1909 in Hampshire. She became an aeronautical engineer & daredevil motorcycle racer.

In 1936, Shilling joined The Royal Aircraft Establishment. 5 yrs later, she led a team that designed a device to prevent Merlin plane engines from stalling during flight, which helped the Allies win WWII.

Shilling was also the 2nd woman to earn a Brooklands Gold Star for lapping the track at >100mph. #science #history

Want to hang out next Thursday night (or Friday depending on where you live)?

I'm joining the one & only @bschillace for a live conversation about #science #politics & culture.

We may discuss why so many people believe things that aren't true. Or explore how we got into this predicament.

The Pecular Book Club is "a safe haven of nerdery for all peculiar people w bizarre interests."


This should be fun!

Wonderful! I love the runner-up, 'The Scholar's Dream', on browntail moths, to the music of Saint-Saëns' Danse Macabre:

Overview & other category winners here:

#DanceYourPhD #moth #kangaroo #epigenetics #circadian #dance #zoology #science #SciComm #SocialScience #biology #chemistry #physics

Every year, students around the world submit videos to a "Dance Your PhD" contest. The goal is to "explain your research through interpretive dance."

This year's fabulous winner, Weliton Menário Costa, explores kangaroo behavior & promotes diversity. It is, by far, the best I've ever seen.

Go watch! #science #dance #art #animals

There are massive differences in the GHG emissions of different foods & "local" isn't always best for the environment.

This chart continues to be a great reference I return to in my work. Source: #science #climate #food
