RMIT University researchers have tested a more effective way to capture microplastics from wastewater, using a combination of microbubbles and nanobubbles to achieve removal rates of more than 90%.

The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.

In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, ...

Phase transformations—in which a material changes from one crystal structure to another, thereby acquiring dramatically different properties—are ubiquitous in nature. Understanding the microscopic mechanisms of these transformations ...

Astronomers have used the European Southern Observatory's Very Large Telescope (ESO's VLT) to study the composition of 3I/ATLAS, the brightest interstellar object ever seen, in detail. By measuring specific chemical fingerprints—the ...

New research has revealed that water behaves differently when confined to spaces just one molecule thick. For the first time, scientists have directly measured the vibrational signatures of truly two-dimensional water. In ...

New research proving bumblebees exhibit emotion-like behaviors—previously thought to exist only in mammalian species—has implications for how scientists understand the consciousness of insects.

The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed ...

One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. ...

When massive stars die, they unleash some of the most powerful explosions in the universe. Yet not all supernovae are created equal. Some continue to shine brightly for months or even years as their expanding debris crashes ...

Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb), is the world's deadliest single-agent infection, responsible for 1.23 million deaths in 2024, according to the World Health Organization. The bacterium's ...

Neutron sources can be directly identified from measured spectra rather than proxies using inference tools adapted from cosmology, according to a University of Michigan Engineering study published in Physical Review Applied. ...
