Discovery marks the first time a radio signal has been confirmed as coming from a single planet rather than an entire system.

First Evidence for Quantum Gravity?

In October 2022, a detector in Russia caught a single photon with an energy far beyond anything our particle colliders can produce. According to physics as we know it, it should never have made it to Earth. Now a team of physicists says it might be the first evidence for quantum gravity. Let’s take a look.

David Loy on Zen, EcoDharma, AI and Story
“How do I respond appropriately?”
Zen teacher David Loy thinks that question might be the whole of wisdom. It isn’t asking what the solution is or who’s to blame. It’s asking what this moment actually demands of me.
When we sat down in 2022, the #ClimateCrisis already felt like it couldn’t wait, and #AI was still something most people filed under “later.” Neither one is “later” anymore.
Loy has spent his life trying to close a gap the East and West kept widening: personal enlightenment on one side, social revolution and systemic change on the other. He argues we can no longer keep them apart. Individuals make society, but society also makes individuals. Change only one and you haven’t changed much.
We talked for two hours, and it went to places I didn’t expect. Why he calls this the most dangerous moment in our civilization’s history. What a fellow Zen teacher’s idea of brain implants and the gamification of enlightenment says about us. How the “delusion of separation” connects #ExistentialRisk, democracy, and the dream of colonizing Mars.
Then he got to stories, and to why he believes the world is made of them.
Reprogramming Life: Aging, Gender & Identity
Biology is Not Destiny.
For most of human history, aging seemed irreversible and the body’s fundamental characteristics appeared fixed. Today, advances in gene therapy, stem cell biology, epigenetics, and cellular reprogramming are challenging those assumptions and opening possibilities once considered impossible.
In Reprogramming Life, stem cell biologist and biotechnology entrepreneur Dana Larocca brings the history of biotechnology to life through the story of her own scientific career. Her journey begins with a childhood question—why do we grow old?—and leads to the frontiers of regenerative medicine and longevity research.
Along the way, Dana led the team that reprogrammed cells from a 114-year-old woman, showing that even cells from someone approaching the known limit of human lifespan could be returned to a youthful, embryonic-like state capable of becoming many different kinds of cells.
At the same time, she was living another story of transformation. From childhood, Dana knew herself to be female, but she kept that truth private for decades while building a career, marrying, and raising a family. She eventually transitioned at the age of sixty-three, giving the idea of biological flexibility a deeply personal meaning.
At its heart, Reprogramming Life asks how much of our biology is truly fixed—and what new choices may become possible as we learn to reprogram life itself.

Elusive ‘Geoneutrinos’ Are Building a New Map of Earth’s Volatile Interior
Scientists are using ultra-sensitive underground particle detectors around the world to track geoneutrinos—subatomic particles generated deep within the planet by the radioactive decay of elements like uranium and thorium. By detecting these “ghostly” particles, researchers are beginning to map and understand the radioactive heat engine driving Earth’s plate tectonics, mantle convection, and magnetic field.
* Deep Underground Observatories: To catch geoneutrinos, detectors must be shielded from background cosmic rays.
Experiments like SNO+ (located 2 km underground in Sudbury, Canada) and the JUNO experiment in China utilize thousands of tons of ultrapure liquid and light sensors buried deep in rock mines to capture the faint flashes of light produced when neutrinos hit the detectors.
* Probing Earth’s Hidden Heat: A significant portion of the heat driving Earth’s interior processes comes from radioactive decay within the crust and mantle. Because neutrinos pass through solid rock unhindered, geoneutrinos provide a direct line of sight into inaccessible regions thousands of kilometers below the surface.
* Building a Global Map: A growing network of underground detectors is gathering substantial new measurement data, helping geoscientists test and refine models of Earth’s mantle composition, thermal budget, and volatile internal dynamics.
1. What are Geoneutrinos?
Neutrinos are extremely lightweight, subatomic particles that rarely interact with ordinary matter. Geoneutrinos are specifically the electron antineutrinos produced when radioactive isotopes—primarily uranium, thorium, and potassium—decay deep within Earth’s crust and mantle.
SKA may detect magnetic fields on distant exoplanets
Studying exoplanets has given astronomers insights into the characteristics that could help them find life beyond Earth. For years, astronomers thought an exoplanet’s location in a star’s habitable zone was enough to make it an Earth-like world. But some stars are more active than our sun, exposing planets in their habitable zones to far more radiation than Earth receives. Astronomers have increasingly recognized that a planet’s magnetic field, which shields Earth from harmful radiation, could be a key characteristic in identifying Earth-like worlds.
Now, an international team of scientists is shedding light on how to study exoplanet magnetic fields in a chapter published in Advancing Astrophysics with the SKA II, a 2026 science book sponsored by the Square Kilometer Array Observatory (SKAO). The researchers discuss how the SKA could be used to study magnetic fields not only on exoplanets but also on ultracool dwarfs (UCDs). The chapter is also available on the arXiv preprint server.
As their name suggests, UCDs are stars smaller and cooler than our sun. Some are brown dwarfs, objects between Jupiter and the sun in size that did not grow large enough to achieve nuclear fusion.
