Scientists have revealed for the first time that some fish sneak up on their prey by hiding behind sharks. The previously unknown behaviour was discovered by a team of researchers, including scientists from the University of Edinburgh, studying sandbar sharks in the Mediterranean Sea.

Underwater video footage captured by divers and remotely operated vehicles shows a type of small predatory fish – called blue runners – using the sharks for cover while they hunt.

In a recent study published in Engineering, researchers have developed a hybrid keratin and liquid metal hydrogel. This innovative material shows promise in creating wearable electronics for monitoring the health of marine inhabitants, addressing limitations of traditional hydrogels in mechanical and conductive properties.

- Study from University of Leicester describes a new species of fossil that is 444 million years-old with soft insides perfectly preserved

- Research ‘ultramarathon’ saw palaeontologist puzzled by bizarre fossil for 25 years

- Revealed to be an entirely new kind of arthropod and named after lead researcher’s mum

Proof-of-concept work uses unique, safe particles to remove microplastics in a single cycle.

Marine life in the deep ocean can take decades to recover from the impact of deep-sea mining for rare metals, new research shows.

Evolving roughly 27 different times in the long history of fish, bioluminescence—the biological production of light—is one of the flashier survival tools used for luring prey, communication, and recognizing potential mates among various species. In a new study published in Ichthyological Research, an international team of researchers studied the organs that produce light in Vinciguerria mabahiss, a rare species of fish from the Red Sea. This paper marks the first-ever close examination of these organs, providing key information on their structure and how V. mabahiss uses bioluminescence to make its way through the water—and laying the foundational groundwork for future scientists studying fish bioluminescence.

A study published in Engineering provides a comprehensive review of actuation and locomotion methods for miniature underwater robots (MURs). Titled "Actuation and Locomotion of Miniature Underwater Robots: A Survey," the research summarizes key propulsion technologies, evaluates their advantages and challenges, and explores future trends in MUR development for underwater exploration and marine applications.

Tropical marine low clouds play a crucial role in regulating Earth’s climate. However, whether they mitigate or exacerbate global warming has long remained a mystery. Now, researchers from the School of Engineering at the Hong Kong University of Science and Technology (HKUST) have developed a groundbreaking method that significantly improves accuracy in climate predictions. This led to a major discovery – that tropical cloud feedback may have amplified the greenhouse effect by a staggering 71% more than previously known to scientists.
