Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe. Their progenitors, protoclusters, show these galaxies in their infancy, offering a window to study how ...

The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown ...

A portable biosensor developed at La Trobe University may allow rapid, on-site detection of toxic "forever chemicals" in water, removing the need for samples to be sent to specialist laboratories.

Microbes often display cooperative behavior in which individual cells put in work and sacrifice resources to collectively benefit the group. But sometimes, "cheater" cells in the group may reap the benefits of this cooperation ...

Despite the immense amount of genetic material present in each cell, around 3 billion base pairs in humans, this material needs to be accurately divided in two and allocated in equal quantities. The centromere, located in ...

Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of its least understood components may be interacting, offering a rare window into the darkest recesses ...

Astronomers from Serbia and Russia have conducted deep optical observations of a cloud of neutral atomic hydrogen, designated FAST J0139+4328. Results of the observational campaign, published December 31 on the arXiv preprint ...

In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished ...
