In a recent SETI Live conversation, Beth Johnson spoke with William J. Welch Postdoctoral Fellow Dr. Karen Perez, lead author of a new study reporting the possible discovery of a pulsar candidate near the Galactic Center. Using data from the Breakthrough Listen Deep Pulsar Survey and observations with the NSF Green Bank Telescope, Dr. Perez and collaborators are investigating one of the most important regions of the Milky Way.

PRESS RELEASE: https://www.seti.org/news/why-seti-might-have-been-missing-alien-signals/
A new study by researchers at the SETI Institute suggests stellar “space weather” could make radio signals from extraterrestrial intelligence harder to detect. Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more difficult to detect in traditional narrowband searches.

Although the Nonprofit Industrial Complex has some sophisticated gatekeepers barring access, I've renewed my efforts to find San Francisco Bay Area cooperators interested in my proposed nonprofit for unique S.T.E.A.M.-focused ArtScience demonstration projects that serve the common good.
While general participants are welcome, I need the commitment of board-level founders.

Why did Louis de Broglie, Nobel laureate in physics, abandon his own pilot wave theory?

Blue Dot host Dave Schlom is joined by neuroscientist and animal intelligence advocate Dr. Lori Marino, who was recently named the 2026 winner of the Frank Drake Award by the SETI Institute. Marino was one of the first scientists to determine that bottlenose dolphins can recognize themselves in a mirror, a key test of cognitive awareness.

Such a great story! 😍
"Fold paper. Insert lens. This $2 microscope changes how kids see the world"
https://www.npr.org/sections/goats-and-soda/2024/11/24/g-s1-35181/microscope-lens-students-foldscope
"Once assembled the Foldscope is the size of a bookmark. It’s small enough to fit in a pocket and can magnify up to 140 times.
Each unit costs around $2 to make. Foldscopes are offered for free to kids in lower income countries; various upgraded models with extras are sold as well, earning money for the charitable endeavor."

#OTD in 1922.
At Toronto General Hospital, 14-year old Leonard Thompson became the first human to receive an injection of insulin as a treatment for diabetes, administered by Dr. James Collip. Thompson developed an allergic reaction to the injection. Additional work was done to refine the treatment and a second dose given on January 23.

We Didn’t All Evolve From One Population Of Early Humans, New Research Claims
"We've arrived at a place where we can begin to address some key questions about our shared ancestry and even emerge with new questions we haven't known to ask before."

Under #Trump, #EPA scientists say managers encouraged them to delete evidence of chemicals’ harms, including #cancer, miscarriage and neurological problems, from their reports. And in some cases, they said, their managers deleted the information themselves.

Mária Telkes died #OTD in 1980. She was a Hungarian-American biophysicist, engineer, & inventor who worked on solar energy technologies.
During World War II, she developed a solar water distillation device, deployed at the end of the war, which saved the lives of downed airmen and torpedoed sailors. In the 1940s she and architect Eleanor Raymond created one of the first solar-heated houses, Dover Sun House, by storing energy each day.
"Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve."

Dale Andersen’s Astrobiology Antarctic Status Report: 11 January 2026
This morning, Dale Andersen and his team departed their arrival point at Ultima Air base and headed south to Lake Untersee. They departed around 6:30 am ET and arrived at the shore of Lake Untersee at their traditional base camp location (at S 71.260082° E 13.506017° at an elevation of 2,645 ft.) around 12:00 – 12:30 pm ET.

J. J. Thomson, who was born #OTD in 1856, received the Nobel Prize in Physics in 1906 for his discovery of the electron, the first subatomic particle to be found.
Thomson was also a teacher, and seven of his students went on to win Nobel Prizes: Ernest Rutherford, Lawrence Bragg, Charles Barkla, Francis Aston, Charles Thomson Rees Wilson, Owen Richardson and Edward Victor Appleton.

In happier news, it's been a great week for learning strange new things about the universe. A few highlights:
The Rubin Observatory opened its eyes & immediately discovered 1900 asteroids, including the fastest-spinning large asteroid (once every 1.88 minutes!).

William Herschel discovers Titania and Oberon, two moons of Uranus.
Orbiting at a much greater distance from Uranus are the ten known irregular moons. The planet's magnetosphere is highly asymmetric and has many charged particles, which may be the cause of the darkening of its rings and moons.
"Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature."

What Is Entropy? A Measure of Just How Little We Really Know.
Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world than a reflection of our growing ignorance. Embracing that truth is leading to a rethink of everything from rational decision-making to the limits of machines.
