Researchers have built an optical clock using an array of trapped ions—an architecture that can be scaled up to boost the clock’s precision.
So-called “infinite-layer” nickelate materials, characterized by their unique crystal and electronic structures, exhibit significant potential as high-temperature superconductors. Studying these materials remains challenging for researchers; they have only been synthesized as thin films and then “capped” with a protective layer that could alter properties of the nickelate layered system.
To address this challenge, a team led by researchers at the National Synchrotron Light Source II (NSLS-II)—a U.S. Department of Energy (DOE) Office of Science user facility at DOE’s Brookhaven National Laboratory—used complementary X-ray techniques at two different beamlines to gain new insights into these materials. Their results were published in Physical Review Letters.
A dry material makes a great fire starter, and a soft material lends itself to a sweater. Batteries require materials that can store lots of energy, and microchips need components that can turn the flow of electricity on and off.
Each material’s properties are a result of what’s happening internally. The structure of a material’s atomic scaffolding can take many forms and is often a complex combination of competing patterns. This atomic and electronic landscape determines how a material will interact with the rest of the world, including other materials, electric and magnetic fields, and light.
Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, as part of a multi-institutional team of universities and national laboratories, are investigating a material with a highly unusual structure—one that changes dramatically when exposed to an ultrafast pulse of light from a laser.
An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: the origin of the ventral nerve cord, a vital part of the central nervous system, in ecdysozoan animals—a group that includes insects, nematodes, and priapulid worms.

Henri Poincarés major work on a theory of the electron is “Sur la dynamique de l’électron”.1 It is considered, by some, as evidence that Poincaré, more than anyone else in the late 19th and early 20th centuries, anticipated Einstein’s 1905 theory of relativity.2
OpenAI says no money changed hands in the collaboration. But because the work could benefit Retro—whose biggest investor is Altman—the announcement may add to questions swirling around the OpenAI CEO’s side projects.
Last year, the Wall Street Journal said Altman’s wide-ranging investments in private tech startups amount to an “opaque investment empire” that is “creating a mounting list of potential conflicts,” since some of these companies also do business with OpenAI.
In Retro’s case, simply being associated with Altman, OpenAI, and the race toward AGI could boost its profile and increase its ability to hire staff and raise funds. Betts-Lacroix did not answer questions about whether the early-stage company is currently in fundraising mode.
In a study published in the Astrophysical Journal, a team of researchers led by Kristen McQuinn, a scientist at the Space Telescope Science Institute and an associate professor in the Department of Physics and Astronomy at the Rutgers University-New Brunswick School of Arts and Sciences, has reported finding that Leo P, a small galaxy and a distant neighbor of the Milky Way, “reignited,” reactivating during a significant period on the timeline of the universe, producing stars when many other small galaxies didn’t.
By studying galaxies early in their formation and in different environments, astronomers said they may gain a deeper understanding of the universe’s origins and the fundamental processes that shape it.
McQuinn and other members of the research team studied Leo P through NASA’s James Webb Space Telescope, a space-based apparatus that features a large, segmented mirror and an expansive sunshield, both of which enable it to capture detailed images of distant celestial objects.
Summary: A comprehensive study mapped neuronal IL-1R1 (nIL-1R1) expression in the mouse brain, highlighting its role in sensory processing, mood, and memory regulation. Researchers found that neurons expressing IL-1R1 integrate immune and neural signals, revealing connections between inflammation and brain disorders like depression and anxiety.
The study pinpointed key regions, such as the somatosensory cortex and hippocampus, where IL-1 signaling influences synapse organization and neural circuit modulation. Notably, neuronal IL-1R1 modifies synaptic pathways without triggering inflammation, suggesting distinct functions in the central nervous system.
Have you read on social media about the “once in 396 billion years” planetary alignment happening on Jan. 25? Guess what? Social media is not reliable. Here’s what’s really going on — and why you don’t have to wait.
Four planets are easily visible to the naked eye this month. Next month, for a short period, there will be five. It’s not irregular, not particularly rare, and certainly not some kind of weird alignment—as the online hype would have you believe—but it is a spectacular sight. But is it one of the best stargazing and astronomy sights of 2025?
Here’s the truth about the so-called “planet parade” and when you can see it as its best all this month and during February.
