Natural “Space Weather Stations” to Study Planet Habitability

“This is a great example of a serendipitous discovery, something we didn’t expect to find but that will give us a new window into understanding planet-star relationships,” said Dr. Luke Bouma.

How can scientists determine if exoplanets orbiting M-dwarf stars are habitable? This is what a study recently presented at the 247th Meeting of the American Astronomical Society hopes to address as a team of scientists investigated how stellar activity from M-dwarf stars could influence planetary habitability. This study has the potential to help scientists to narrow constraints for conditions regarding finding life beyond Earth.

For the study, the researchers explored a unique type of M-dwarf star called a complex periodic variable (CPV), which are young M-dwarf stars that have been observed to have periodic decreases in brightness. While brightness dimming is often attributed to a planet passing in front of the star, or even gas and dust, astronomers were perplexed regarding this particular phenomenon. Their initial hypothesis was the brightness dips resulted from bright and dark regions on the star’s surface.

After significant analysis, the researchers discovered that the brightness dips were caused by a “donut” of super-heated gas called plasma, which all stars are made of, trapped within the star’s magnetic field. As the donut rotated around the star, it caused periodic dips in brightness. Along with estimating that approximately 10 percent of M-dwarf stars could be designated as CPVs, they also note this unique stellar could help gain greater insight into how it influences planetary conditions, which the researchers dubbed “space weather stations”

Meta-Harness: End-to-End Optimization of Model Harnesses

Think of a Large Language Model (LLM) like a brilliant scholar. To do their job well, they don’t just need their own brain; they need a good workspace—a desk with the right books, a filing cabinet that’s easy to navigate, and a clear set of instructions on how to process information. In the tech world, this “workspace” is called a harness.

Up until now, these harnesses have been built by human engineers through trial and error. While we have tools to automatically improve the AI’s “brain” (the model weights), the code that actually manages the AI’s information has remained stubbornly manual.

Meta-Harness automatically optimizes model harnesses — the code determining what to store, retrieve, and present to an LLM — surpassing hand-designed systems on text classification, math reasoning, and agentic coding.

Brain Disease Decades Later? Study Links Childhood Surgery to Amyloid Build-Up

A new report describes two unusually young patients who developed cerebral amyloid angiopathy decades after childhood cardiac surgery. Researchers suspect amyloid-beta may have been inadvertently transmitted through cadaver-derived surgical material used at the time. The finding does not mean Alzheimer’s is contagious in everyday life, but it does add to evidence that rare past medical exposures may seed abnormal brain protein buildup years later.

Aerosol jet printing creates durable, low-power transistors for next-generation tech

Tiny electronic devices, called microelectronics, may one day be printed as easily as words on a page, thanks to new research from scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. Building on years of progress in printed electronics, the team has shown how to create durable, low-power electronic switches, called transistors, by combining custom inks and a specialized printing process.

These switches, which control the flow of electrical current to turn circuits on and off, use very little power, are built to last and show new behaviors not seen in earlier printed devices. This research could help create flexible sensors, smart windows and other new technologies that need reliable, energy-saving electronics. The work is published in Advanced Materials Technologies.

How aerosol jet printing works The scientists used a method called aerosol jet printing, which works like an inkjet printer. But instead of regular ink, it uses specially formulated ink made from nanoparticles. The printer turns the ink into a fine mist and sprays it onto a surface, building up layers to form electronic parts.

Astrophysicists trace the origin of valuable metals in space, from colliding stars to merging galaxies

Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a sudden flash of gamma rays, streaming through the universe. These gamma rays traveled for 8.5 billion years before reaching Earth.

In a new study, our team of astrophysicists examined this gamma-ray signal. We learned that the stellar collision it came from was likely caused by an even more catastrophic encounter—a merger between two galaxies.

This is the first time astronomers associated this type of signal with such a large-scale galactic interaction. Our finding offers new insight into how stellar collisions spread metals across the universe.
