Born in 1821, Elizabeth Blackwell was determined to become a physician. But she was rejected from every med school she applied to bc she was a woman. She was finally admitted to Geneva College, but her acceptance letter was intended as a joke.

Dr. Blackwell was the first woman to receive an M.D. from a U.S. med school & championed women in medicine. Eventually, she opened a clinic, started a medical college for women & became a professor. cfmedicine.nlm.nih.gov/physici… #science #history #HistoryRemix

Born in 1914, Hedy Lamarr was a famous American actress who pioneered the technology that would lead to WiFi, GPS, cell phones & Bluetooth communication.

Lamarr was brilliant. Among many fascinating inventions, she developed a new communication system with composer George Antheil that used “frequency hopping” among radio waves.

Once called the “most beautiful woman in the world," Lamarr is now remembered as "the mother of Wi-Fi."

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. space.com/17439-caroline-hersc… #history #HistoryRemix

“There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”

Fission is in the news, but few recognize that a woman physicist was behind the discovery.

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 w/o 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. aps.org/publications/apsnews/2… #women #history #science #HistoryRemix

Henrietta Lacks was a poor, Black, young mother diagnosed cervical cancer in 1951. When her cells were collected w/o consent, scientists saw they multiplied fast.

“HeLa” cells changed #science. They’re used globally to study viruses, drugs, hormones, genes, diseases & develop vaccines. Lacks passed away at 31 w no recognition.

Rebecca Skloot’s beautiful book about her life & legacy is changing that. Now her statue will replace Robert E. Lee in VA. nytimes.com/2022/12/20/us/henr… #history #HistoryRemix

Rosalind Franklin’s research was crucial to discovering DNA’s double helix structure 🧬 but it was James Watson & Francis Crick who received the credit & Nobel Prize.

Unknown to Franklin, the pair saw her unpublished data & X-ray diffraction images, inspiring their model. They never acknowledged her contribution until after her death.

How many discoveries & innovations of #women do we attribute to the men who took credit for their ideas?

Physicist John Tyndall is often credited w discovering the greenhouse effect, which he wrote about in 1859.

But female scientist Eunice Foote published a paper - 3yrs earlier - demonstrating how atmospheric water vapor & CO2 affected solar heating. She theorized that heat trapping gases in Earth’s atmosphere warm its #climate.

Tyndall was widely read. And Foote, being a woman, wasn't even permitted to present her own work.

Some of us divergent types can't help but think systemically. I have presented to several groups of engineers about building innovative teams. I recommend doing deep research in a very different field, like biology (as opposed to computer science for example), when searching for inspiration. I have several good examples and love the idea of transdisciplinary thought. You have my vote.

#science #climate

Rather than teach #science by compartmentalizing biology, chemistry, physics, etc., we should focus on systems thinking.

The world is interconnected - oceans, food, #climate, energy, health, security, biodiversity & on.

When more of us, all around the world, consider how the pieces fit together & influence each other, we’ll be better equipped to meet global challenges.

Hi #science #research #mastodon community! A few days ago, a post of mine recieved a lot of attention. Thanks for the engagement and the very interesting suggestions! neuromatch.social/@LeonDLotter…

On #Twitter, I loved the common practice of writing threads explaining new #preprints and #papers in an understandable way.
I uttered my concern that through the chronological timeline here people might miss interesting science. A solution would be to agree on names for hashtags and/or a.gup.pe groups to ease tracking these "paper threads".

Following tags were named more then once: #newPaper #paperThread #preprint #researchPaper #mastoPrint #tootPrint.
Also, there was #tootorial, but that might be a slightly different category?

I heard people like participation - so let's do a poll! What's your favourite tag for threads explaining research articles? 📊​ Multiple choices possible!

12 years ago, my 2nd book, The Science of Kissing (Hachette, 2011) came out. It’s about the neuroscience, biology, evolution, history, real chemistry & potential future of connection.

With #ValentinesDay around the corner, would fellow #science & #culture nerds on #Mastodon be interested in a few facts & stories from the book?

Born in 1883, Elmer Samuel Imes was the 2nd Black American to receive a physics PhD in the U.S.

His pioneering experimental work measured of the rotational–vibrational spectra of diatomic molecules.

Imes faced many obstacles bc of his race & blazed trails in science for many who followed. He was also interested in how science & culture intersect & married Nella Larsen, a great writer of the Harlem Renaissance. He passed away in 1941. physicstoday.scitation.org/doi… #history #science #HistoryRemix

This video shows the bacteria in only about 0.001 ml of water from my jar. At the beginning the focus is on the upper plane, and then I slowly move the focus down into the seething mass. This is terrifying. #horror #science #bacteria #OhMyGodWhatHaveIDone

Well, it's Groundhog Day, again.*

Okay, so after watching #TheLastOfUS on #HBO, I wondered if #SciFi#zombies (basically a virus, bacteria, etcetera, cause craziness & not a living dead scenario) could occur in humans.

According to #science, the answer is yes. At the 10:15 mark of this video mentions a parasitic protozoan that replaces mammels fear of #cats with a love for cats (or at least their scent.

youtu.be/jM5jf-8ekVA
I guess this explains why #Caterday is so popular online (regardless of the social platform used).

Although it usually infects mice 🐁, this parasite can affect humans as well, as it wants us to be eaten by cats (even big cats like lions). From #ScienceFiction to science fact. Crazy if you ask me!

In 2007, a small group of concerned citizens co-founded the nonpartisan ngo Science Debate. The goal was simple: Science Debate asked presidential candidates to answer science policy questions related to issues like competitiveness, space exploration, & pandemic response.

Why? If candidates addressed #science issues, they should be more likely to arrive in office with a plan for how to deal with challenges related to health, tech & the environment. open.substack.com/pub/sheril/p… #politics

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. theconversation.com/marie-thar… #science #history #HistoryRemix

Nature is full of surprises. Meet Costasiella kuroshimae, an adorable species of sea slug known as “leaf sheep.”

At no more than 8mm, these tiny ocean critters graze on algae & keep chloroplasts in their bodies for up to 10 days. They supplement their diet through photosynthesis to create energy, which is why they’re sometimes referred to as “solar-powered sea slugs.” bbc.com/travel/article/2021032… #nature #science #SharedPlanet
