"In 1912, Oskar von Miller, an electrical engineer and founder of the Deutsches Museum, had an idea: Could you project an artificial starry sky onto a dome, as a way of demonstrating astronomical principles to the public?"
@stefan I have no idea why, but I’d pegged them as something from the 1800s. They’re still one of my favorite places in a science museum to go-so magical! 🤩
There are so many different types of researchers. Weather researchers, climate researchers, brain researchers. And within those categories, the nuances (like memory researchers).
When someone says they are an X researcher, what does that imply to you? In other words, what qualifies? Does it just imply that they are curious about X? Or perhaps that they know a bit more about it - perhaps they've mastered some scholarly literature or they've done at least one experiment? Or maybe even published a paper in a peer reviewed journal? Or maybe even more - perhaps they have a body of work on the topic; maybe they even run a lab (and have grants to support X research).
On one hand, no one should gate keep curiosity! On the other, certain terms imply knowledge and qualifications. I'm a "researcher". But just because I know a lot about memory doesn't automatically mean that people should listen to me about climate or economics. And I once read a very good book about ecosystems, but I don't think that means I should quality as an ecosystem researcher. So what, then, might instead?
@vicgrinberg I'm just saying that if you only count people who have already had a major impact in their field as researchers, you're excluding a lot of early-career researchers. Publications are hard to evaluate if they're not in your field. We all know that rubbish sometimes gets published in peer reviewed journals. In practice, we tend to look at the reputation of the institution or department that the person is working in.

More than five million people are bitten by snakes every year, resulting in thousands of deaths and permanent disabilities. Those chilling statistics didn’t stop one PhD student, João Miguel Alves-Nunes, from stepping on deadly and dangerous vipers more than 40,000 times. Alven-Nunes tells Science about putting himself in danger for a scientific experiment, what happened when one snake’s fangs broke through his protective boot, and why even that harrowing experience won’t diminish his love for "working with these animals." https://flip.it/zRaVCF#Science#Animals#Snakes#Health
"Two common goals of these cosmetic 'normalizing' surgeries on children’s genitals are to enable #heterosexual penetrative intercourse, and to help the child #conform to #gender and sexual norms"
@Wuzzy all forms of nonconsensual genital cutting should be banned, including penile circumcision and medically unnecessary intersex surgeries. Right on.
Reprogrammer les cellules immunitaires : la révolution des cellules CAR-T contre le cancer
C’est une avancée importante pour la lutte contre certain #cancer. Dans ce billet Sciences, on vous parle de la révolution des cellules CAR-T, qui sont au cœur d’une stratégie d’immunothérapie cellulaire en plein développement visant à combattre le cancer en s’appuyant sur le propre système #immunitaire du patient.
For the fifth time in three years, a group of orcas has sunk a ship in southwest Europe. This time an unknown number of killer whales attacked a 50-foot sailing yacht in the Strait of Gibraltar, ripped open its hull and sent the boat to the seafloor. Live Science has more, including what happened to the crew and why researchers believe the attacks are a learned behavior that could increase in the coming months. https://flip.it/0KoMeL #Science#KillerWhales#Orcas#Europe
Why we can't have nice things...We've known about paper mills and lack of sufficient reviewers being a problem for a while now. It's been getting worse and worse.

A survey of more than 3000 physical science researchers in over 100 countries reveals a sharp split in attitudes towards the use of AI in peer review, with 35% saying it will be harmful, 29% saying it will be beneficial, and 36% predicting it will have no impact.
Ever wonder how soft bodied creatures exert forces as they move? Now a new theory by @mchtweet & co reveals how starfish feet propel the echinoderms, how worms burrow & how squid propel their tentacles.
Johannes Kepler confirms his previously rejected discovery of the third law of planetary motion (he first discovered it on March 8 but soon rejected the idea after some initial calculations were made).
The elliptical orbits of planets were indicated by calculations of the orbit of Mars. The third law expresses that the farther a planet is from the Sun, the slower its orbital speed, and vice versa.
@gutenberg_org
The other weird law that he found was that planets sweep the same area for time. If you take the elliptical path over time and create a pie shaped wedge from the focal point, no matter how distant or how close, the area of the pie shape will be the same in the same amount of time. Weird but true.
