First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
Researchers achieve tunable coherent population trapping in a double quantum dot system
A research team has achieved coherent population trapping (CPT) in a semiconductor double quantum dot (DQD) system......»»
Leap Seconds May Be Abandoned by the World’s Timekeepers
We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?.....»»
The neutron lifetime problem—and its possible solution
Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes.....»»
Who will host the 2025 Oscars? Your guess is as good as Hollywood’s
Who will host the 2025 Oscars? No one knows. The Academy of Motion Picture Arts and Sciences is currently searching for talent to host the March ceremony......»»
Color complexity in social media posts leads to more engagement, new research shows
If you work in digital marketing, you don't need to be told a picture's worth a thousand words. More than half of content marketers say images are crucial for achieving their social media goals, and a staggering 70% of users prefer image-based posts.....»»

Dual-species atomic arrays show promise for quantum error correction
A study in Nature Physics has realized a dual-species Rydberg array combining rubidium (Rb) and cesium (Cs) atoms to enhance quantum computing and its applications......»»
Expansion in situ genome sequencing innovation makes hidden DNA-protein interactions visible
Harvard scientists have unveiled a new technique called expansion in situ genome sequencing (ExIGS) that combines existing in situ genome sequencing (IGS) with expansion microscopy (ExM). The innovation allowed researchers to link nucleus abnormaliti.....»»
Interdisciplinary advances in microcombs: Bridging physics and information technology
Researchers are excited about the potential of microcombs, miniature devices that generate precise time and frequency standards. These microcombs could revolutionize fields from high-speed communication, high-resolution measurements to precise atomic.....»»
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs
Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into lig.....»»
Here’s a closer look at the Samsung Galaxy S25’s new displays
Well-known tipster Ice Universe is back with a picture of the S25, S25 Plus, and S25 Ultra displays. And yes, it confirms a lot of what we knew......»»
"Invisibility" and quantum computing tipped for physics Nobel
An "invisibility cloak", an atomic force microscope or quantum computing are some of the scientific achievements that could win a Nobel prize in physics Tuesday......»»
Beyond "one pore at a time": New method of generating multiple, tunable nanopores
Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for osmotic power generators......»»
Q&A: Researchers examine link between light pollution and interest in astronomy
Picture walking outside on a dark, cloudless evening. You look up to admire the stars—maybe even a planet, if you're lucky—and a sense of wonder washes over you. New research from the University of Washington shows this might be more than a memor.....»»
Nanopillars create tiny openings in the nucleus without damaging cells
Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells.....»»
In fear of more user protests, Reddit announces controversial policy change
Moderators now need Reddit's permission to turn subreddits private, NSFW. Enlarge (credit: Silas Stein/picture alliance via Getty Images) Following site-wide user protests last year that featured moderators turning thous.....»»
A new apparatus for analyzing partial coherence in integrated photonic networks
Anyone familiar with optics labs is familiar with the extremes of light coherence: laser beams are highly coherent, producing clear interference patterns used for precise applications like atomic manipulation or precise sensing. In contrast, light fr.....»»
Research team succeeds in ultra-fast switching of tiny light sources
Extremely thin materials consisting of just a few atomic layers promise applications for electronics and quantum technologies. An international team led by TU Dresden has now made remarkable progress with an experiment conducted at Helmholtz-Zentrum.....»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
How large language models are changing collective intelligence
Within teams, organizations, markets and online communities, ideas from a larger group can help to solve complex problems. Large language models (LLMs) are emerging as powerful tools to unlock even greater potential. Picture an online forum where tho.....»»
