In the intriguing realm of star-forming galaxies, the key factor isn’t the total amount of gas but rather its strategic distribution within the galaxy.

Researchers at the International Centre for Radio Astronomy Research (ICRAR) made the discovery about galaxies by studying the gas distribution that helps create stars.

Using CSIRO’s ASKAP radio telescope located at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory, researchers explored the gas distribution in about 1,000 galaxies as part of the WALLABY survey.

In the name of open science, the multinational scientific collaboration COSMOS on Thursday released the data behind the largest map of the universe. Called the COSMOS-Web field, the project, built with data collected by the James Webb Space Telescope (JWST), consists of all the imaging and a catalog of nearly 800,000 galaxies spanning nearly all of cosmic time. And it’s been challenging existing notions of the infant universe.

“Our goal was to construct this deep field of space on a physical scale that far exceeded anything that had been done before,” said UC Santa Barbara physics professor Caitlin Casey, who co-leads the COSMOS-Web collaboration alongside Jeyhan Kartaltepe of the Rochester Institute of Technology.

“If you had a printout of the Hubble Ultra Deep Field on a standard piece of paper,” she said, referring to the iconic view of nearly 10,000 released by NASA in 2004, “our image would be slightly larger than a 13-foot by 13-foot-wide mural, at the same depth. So it’s really strikingly large.”

Researchers have published the demonstration of a fully-integrated single-chip microwave photonics system, combining optical and microwave signal processing on a single silicon chip.

The chip integrates high-speed modulators, optical filters, photodetectors, as well as transfer-printed lasers, making it a compact, self-contained and programmable solution for high-frequency .

This breakthrough can replace bulky and power-hungry components, enabling faster wireless networks, low-cost microwave sensing, and scalable deployment in applications like 5G/6G, , and .

A new framework for studying chiral materials puts the emphasis on electron chirality rather than on the asymmetry of the atomic structure.

Chirality is a fundamental feature of nature, manifesting across scales—from elementary particles and molecules to biological organisms and galaxy formation. An object is considered chiral if it cannot be superimposed on its mirror image. In condensed-matter physics, chirality is primarily viewed as a structural asymmetry in the spatial arrangement of atoms within a crystal lattice [1]. A perhaps less familiar fact is that chirality is also a fundamental quantum property of individual electron states [2]. Now, Tatsuya Miki from Saitama University in Japan and colleagues introduce electron chirality as a framework to quantify symmetry breaking in solids, focusing on chiral and related axial materials [3]. The researchers propose a way of measuring electron chirality with photoemission spectroscopy.

Scientists at the University of Surrey have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO₂ ‘breathing’ batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today’s lithium-ion batteries.

Until now, Lithium-CO₂ batteries have faced setbacks in efficiency — wearing out quickly, failing to recharge and relying on expensive rare materials such as platinum. However, researchers from Surrey have found a way to overcome these issues by using a low-cost catalyst called caesium phosphomolybdate (CPM). Using computer modelling and lab experiments, tests showed this simple change allowed the battery to store significantly more energy, charge with far less power and run for over 100 cycles.

The study, published in Advanced Science, marks a promising step toward real-world applications. If commercialised, these batteries could help cut emissions from vehicles and industrial sources — and scientists even imagine they could operate on Mars, where the atmosphere is 95% CO₂

Astronomers have filled a large gap in knowledge about Mars’ water cycle. Their research on water percolating from surface to aquifer could change the picture of what early Mars was like, suggesting that less of the planet’s water may have been available to become rain and refill lakes and oceans.

Billions of years ago, water flowed on the surface of Mars. But scientists have an incomplete picture of how the Red Planet’s water cycle worked.

That could soon change after two graduate students at The University of Texas at Austin filled a large gap in knowledge about Mars’ water cycle — specifically, the part between surface water and groundwater.

A team of solar physicists has released a new study shedding light on the fine-scale structure of the sun’s surface. Using the unparalleled power of the Daniel K. Inouye Solar Telescope, built and operated by the National Solar Observatory (NSO) on Maui, scientists have observed, for the first time ever in such high detail, ultra-narrow bright and dark stripes on the solar photosphere, offering unprecedented insight into how magnetic fields shape solar surface dynamics at scales as small as 20 kilometers (or 12.4 miles).

The level of detail achieved allows us to clearly link these stripes to the ones we see in state-of-the-art simulations—so we can better understand their nature. These stripes, called striations and seen against the walls of solar convection cells known as granules, are the result of curtain-like sheets of magnetic fields that ripple and shift like fabric blowing in the wind.

As light from the hot granule walls passes through these magnetic “curtains,” the interaction produces a pattern of alternating brightness and darkness that traces variations in the underlying . If the field is weaker in the curtain than in its surroundings, it appears dark; if it is relatively stronger, it appears bright.
