A temperature dial for more realistic quantum simulations

Scientists from Rice University in the U.S. have developed a way to precisely tune the temperature inside a trapped-ion simulator. The breakthrough means they will be able to run quantum simulations at precise temperatures that better reflect real-world conditions.

Mapping the upper atmosphere with public Starlink satellite data

The space around Earth is becoming increasingly crowded, with thousands of satellites and pieces of debris now sharing low Earth orbit. Even above this region—at altitudes of several hundred kilometers—the extremely thin upper atmosphere can slow satellites, making accurate information on atmospheric density essential for predicting satellite motion and preventing collisions.

First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown

Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing a faint flux of a specific type of particle known as antineutrinos. (Anti)neutrinos are the lightest and most elusive known particles in the universe, allowing them to escape unhindered from both the reactor and the surrounding shielding.

Mapping monsters: Data release unveils all-sky views of supermassive black holes

Data released by the Sloan Digital Sky Survey (SDSS) marks a landmark expansion in the study of accreting supermassive black holes (SMBHs). As part of the fifth generation of the survey (SDSS-V), the Black Hole Mapper (BHM) program is providing unprecedented insights into the masses, growth and physics of quasars and active galactic nuclei (AGN) across cosmic time.

Designing memory-centric chips for future space telescopes

Two proposed computer chip designs could efficiently process data on future space telescopes while they search for Earth–like exoplanets, according to a University of Michigan Engineering study that will be presented at the IEEE Space Computing Conference in August.

Pushing the boundaries of ultracold neutral plasmas

Using a combination of laser cooling techniques and strong magnetic fields, researchers at Colorado State University have for the first time created an ultracold neutral plasma with electrons cooled to temperatures measured to be within one degree Kelvin.

Two materials, one photonic chip: Unlocking a new way to generate light frequencies

Modern photonic chips can pack sophisticated optical functions onto devices smaller than a fingernail. They are increasingly used to generate, manipulate and measure light for applications ranging from communications to sensing. But most of these chips rely on a single material to do the heavy lifting, limiting the range of optical effects they can produce.

Astronomers catch massive star’s death from the first explosive moment

In March 2026, the Einstein Probe detected a brief flash of soft X-rays emitted from a galaxy about 500 million light-years away. The flash, dubbed EP260321a, immediately triggered a worldwide observing campaign. Within an hour, ground-based telescopes began monitoring the source, revealing a rapidly brightening supernova, later designated SN 2026gzf. Two teams of scientists used several NSF NOIRLab facilities to observe the event and monitor its evolving light profile.

New approach to cleaning the inner walls of a fusion system removes another obstacle to near-endless energy

Fusion systems need inner walls that can withstand extreme heat. One promising solution uses liquid lithium to protect the walls, held like water in a sponge made of the exceptionally strong metal tungsten. An advanced manufacturing process can be used to make tungsten into sponge-like wall tiles with lots of pores for flowing liquid lithium. But this process also leaves the tungsten contaminated with other materials, such as carbon, oxygen or nitrogen.

Asteroid Nysa’s rare three-lobed structure challenges formation models

Named for the mythical valley where the god Dionysus was raised in secret by nymphs, the asteroid 44 Nysa inhabits the asteroid belt between Mars and Jupiter. Through observations by the Hubble Space Telescope, astronomers have determined it to be the largest and brightest known member of a rare category of asteroids called “E-types,” made of unusually bright, enstatite-rich material similar to some rare meteorites found on Earth. Separately, models built from how its brightness flickers as it spins hinted it might have an elongated, lopsided shape, often seen in large asteroid pairs.

Bringing it all into focus—computational microscope captures 25.2 billion pixels per second across a wide field of view

When designing microscopes, optical engineers have long faced a trade-off between speed, field of view and resolution. But improving one of these properties typically comes at the expense of another. Now, a UC Berkeley–led team of researchers has found a way to address this challenge, opening the door to new possibilities in the field of microscopy.
