Archimedes Rediscovered: Technology and Ancient History
Advanced imaging technologies help scholars reveal and share lost texts from the ancient world.
In 1907, Johan Ludvig Heiberg discovered something unexpected in a Byzantine prayer book. Beneath the prayers, in faded lettering, he recognized the words of Archimedes.

#FarRight Extremists Embrace #Environmentalism to Justify Violent Anti-Immigrant Beliefs
—
Rather than reject #climate science like many on the right, some have followed the path laid out by environmentalist and white nationalist John Tanton, using concerns about population growth and scarce resources to rationalize their hateful agendas.
Oops,
Pocket mammoths really existed. I only knew them from Elder Scrolls Online:

But according to @wikipedia, they also existed on Crete:

PRESS RELEASE: https://www.seti.org/press-release/scientists-use-allen-telescope-array-search-radio-signals-trappist-1-star-system
Scientists at the #SETI Institute and #PennState University used the Allen Telescope Array to search for signs of alien technology in the TRAPPIST-1 star system. The team spent 28 hours scanning the system, looking for radio signals that could indicate extraterrestrial technology. Although they didn’t find any evidence of extraterrestrial technology, their work provided valuable data and introduced a new way to search for signals in the future. #science
Climate change will continue having a major impact on the planet, but here’s one sign of how a multi-pronged approach can take some of the heat off in the future: Selectively bred corals show that it is possible to improve their heat tolerance even within a single generation. While not a panacea, selective breeding could be a tool for nature conservation. @ScienceAlert explains: https://flip.it/rePdLS

Stars behaving absurdly
For centuries, the only way in which to illuminate the mysteries of black holes was through the power of mathematics.
As celestial entities go, black holes are, paradoxically, both commonplace and extraordinary. They could be seen as commonplace due to their general ubiquity.

Quick reminder that NASA currently has a solar sail in Earth orbit, flapping its wings in the flow of sunshine.

Italian physicist and academic, first woman to have doctorate in science Laura Bassi was born #OTD in 1711. Bassi became the most important populariser of Newtonian mechanics in Italy.

Astronomers from The University of New Mexico, along with U.S. and international researchers, have confirmed the existence of a new giant exoplanet, made possible through a collaboration with citizen scientists around the world.
Several key programs enabled this global effort, including the TESS Follow-up Observing Program Sub Group 1, the Unistellar Citizen Science Network, and the TESS Single Transit Planet Candidate Working Group.
Have you ever wondered why wet dogs shake so much? Science has an answer. 🐕
From @PopularScience: "Lab mice experiments reveal the nerves that trigger this behavior in hairy mammals."
PRESS RELEASE: https://www.seti.org/press-release/seti-institute-invites-applications-2025-william-j-welch-postdoctoral-fellowship
We are pleased to open the call for applications for the 2025 William J. Welch Postdoctoral Fellowship, focusing on "Engineering the Future of Cosmic Exploration." The Fellowship aims to support exceptional early-career scientists in developing and employing novel instrumentation to answer fundamental questions in astronomy and astrophysics, focusing on the search for extraterrestrial intelligence or technosignatures.
PRESS RELEASE: https://www.seti.org/press-release/seti-institute-strengthens-science-advisory-board-five-new-members
The SETI Institute welcomed five new experts to its Science Advisory Board (SAB), broadening its scope in important scientific and ethical domains essential to understanding life and intelligence in the universe. The new members bring expertise in science communication, ethics and philosophy, animal cognition and intelligence, analysis of extraterrestrial materials, and planetary astronomy.
We knew it was going to happen, but the Voyager space probes are getting creaky in their old age.
NASA just had to reactivate Voyager 1's S-band transmitter for the first time in 43 years after a communication breakdown.

Although the peer review system might not be optimal all the times, as it is a victim of the weaknesses of individual reviewers, at least authors can have a little fun at their expense.

I really can't wait until I can revert to just posting about #climatechange, #water, and #science rather than garbage, racism, sexism, and the threat of a fascist takeover of America.
So, here's a pretty picture of water for now.
Two unusual things happened on Earth around 460 million years ago: a bunch of asteroid impacts near the equator & an intense global cold spell.
Possibly both were the result of an asteroid that broke up & gave our planet a pretty but deadly set of rings.

Are the colours in astronomical images real? What do these colours mean? And what about images that aren't taken in visible light?
We get these questions all the time, so in the latest episode of Chasing Starlight we show you how these colourful images are made:
The death toll in the tragic flash floods that ravaged Texas Hill Country continues to rise, and the National Weather Service has taken some heat from officials who say the organization didn’t prepare them for the enormity of the storm. Meteorologists who talked to @WIRED paint a much different picture:
American botanist Catherine Furbish died #OTD in 1931.
She collected, classified and illustrated the native flora of Maine. She devoted over 60 years of her life, traveling thousands of miles throughout her home state and creating very accurate drawings and watercolor paintings of the plants she found.
