Not all asteroids are planet-killers -- most are tiny and others are huge. So what are the largest and smallest asteroids in the solar system?

Most galaxies seemed to be missing a huge proportion of the matter we expected them to have - now researchers may have found its hiding spot, but the discovery contradicts accepted models of galaxy formation

The human brain continues to massively outperform AI technology in a range of tasks, a new study reports. Researchers outline their plans for biocomputers and organoid intelligence systems as future improvements for arti...

Prosopagnosia, or face blindness, is believed to affect up to 2.5% of the population. However, researchers say prosopagnosia may be on a spectrum and the number of cases may be far higher, estimating up to 1 in 33 people...

The idea that male mammals are larger than females has persisted for more than a century, but an analysis of body mass and length in 400 mammal species shows it isn't the norm

Geologists think there may be vast natural stores of hidden hydrogen gas within Earth, but no one is sure how much there is or how much could be recovered for energy

The immune signaling molecule interleukin 1B (IL-1B) is present at higher levels in mouse models of alcohol use disorder. The IL 1B pathway plays a different role in animal models of AUD, causing inflammation in brain ar...

According to researchers, language model AIs like ChatGPT reflect the intelligence and diversity of the user. Such language models adopt the persona of the user and mirror that persona back.

A new study reveals people who have trouble falling asleep within 30 minutes and those who use sleep medications are at increased risk of developing dementia as they age. However, those who have trouble falling back asle...

What would we do if we spotted a hazardous asteroid on a collision course with Earth? Could we deflect it safely to prevent the impact? Last year, NASA's Double Asteroid Redirection Test (DART) mission tried to find out ...

Infrared spectroscopy is a noninvasive tool used to identify unknown samples and known chemical substances. It is based on how different molecules interact with infrared light. You may have seen this tool at airports, wh...

A new purpose-built microscope has been developed that uses the complex properties of UV light to improve image resolution and contrast. Most cells are transparent at visible wavelengths, which means the imaginary compon...

During the Viking Age (A.D. 793 to 1066), Viking raided, explored and traded from what is now Canada to the Middle East.

A water-based detector has been used to spot antineutrinos from nuclear reactions hundreds of kilometres away. It could be used to monitor distant nuclear activities

Studying "mini-brains" in a dish play computer games could help us better understand how human memories form and lead to new forms of AI, as Brett Kagan tells Clare Wilson

Glass nanoparticles trapped by lasers in extreme vacuum are considered a promising platform for exploring the limits of the quantum world. Since the advent of quantum theory, the question "At what size does an object sta...

Creating a porous liquid long seemed impossible. But now we are making them in earnest and they could prove exceedingly handy in industrial chemistry, greenhouse gas storage and even emergency medicine
