Single-shot phase imaging technique can reconstruct transparent objects

A KAIST research team led by professor Mooseok Jang from the Department of Bio and Brain Engineering has developed a single-shot phase imaging technique that reconstructs a phase object—a transparent object such as glass, plastic film or a living cell, which produces almost no visible contrast under an ordinary camera but induces a subtle shift in light called a phase change—from a single measurement, even when the object is fully enclosed between two dynamic scattering layers.

New quantum microscopy trick quadruples microscope resolution

Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now achieved a fourfold resolution boost compared to a classical microscope, using a new optical design that sends one of the entangled photons through the microscope’s optics three times rather than just once.

Trillion-mile gas streamer may explain tilt of triple-star system’s outer planet-forming ring

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 light-years, long—feeding the young triple-star system GW Orionis. These new observations provide the clearest evidence yet for how such “streamers” can tilt and twist the disks where planets are born. The findings are published in The Astronomical Journal.

Milky Way-like simulation reveals how central galactic structures grow together

Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes that led to the formation of two striking features surrounding the black holes at the centers of most galaxies: nuclear star clusters and nuclear stellar disks. Only in the last decade have such galactic structures been observed in the Milky Way and extragalactic systems.

Two decades of blazar observations, and the mysteries keep piling up

Narrow jets of luminous matter may be emitted toward Earth from the nuclei of active galaxies billions of light-years away. The galaxy then appears as a point source and is called a blazar. A Polish-German team of scientists has, for the first time, analyzed the activity of one such blazar over an extended period and, instead of finding answers, encountered an ever-increasing number of intriguing questions.

Super-Earths may be solid deep inside their mantles

Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions in which these phases are reached could help researchers learn more about how planets evolve.

JWST study suggests a handful of ‘leaky’ galaxies reionized the early universe

A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of “leaky” galaxies was responsible for cosmic reionization. The paper outlining this work was posted to the arXiv preprint server on July 24.

We might soon have the technology to reach other star systems

The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth.

X(2370) emerges as glueball-dominated particle in collider experiments

At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball with spin-parity quantum numbers of 0⁻⁺.

Two-qubit entangling gate flags its own errors as detectable photon losses

Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. Typical fixes involve vast amounts of extra hardware qubits, which make computers larger, more expensive and harder to build.

Rare ultra-magnetic star may be key to solving 90-year old quantum cold case

Astronomers may have just confirmed one of the quirkiest aspects of quantum mechanics: that seemingly empty space can alter the behavior of light. This phenomenon, called “vacuum birefringence,” was first predicted nearly 90 years ago by Werner Heisenberg, one of the founding fathers of quantum mechanics. He suggested that even a perfect vacuum should be teeming with “virtual particles” that rapidly pop in and out of existence.
