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.

New perspectives for wound healing and the treatment of chronic diseases

Fibroblasts are specialised connective tissue cells that play a key role in wound healing and tissue regeneration. The recent scientific publication from the University of Leipzig Medical Center shows that fibroblasts respond differently depending on the organ and disease context. Their functions are shaped by their embryonic origin, tissue-specific signals, and pathological stimuli...

Scientific breakthrough brings CO2 ‘breathing’ batteries closer to reality

The lithium-CO2 battery prototype in a jar

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-COâ‚‚ ‘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-COâ‚‚ 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)...

Missing link in early Martian water cycle discovered

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 k...
