By working together, dolphins and net-casting fishers in Brazil each catch more fish, a rare example of an interaction by two top predators that is beneficial to both parties, researchers have concluded following 15 years of study of the practice.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new study has uncovered a new thalattosuchian -- an ancient 'sister' of modern-day crocodiles' ancestors.

The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?

Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.

Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests.

What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.

Scientists have been studying a fish sensory organ to understand cues for collective behavior which could be employed on underwater robots.

Humans retain an understanding of gestures made by other great apes, even though we no longer use them ourselves, according to a new study.

Researchers attempted to identify early symptoms of Parkinson's disease using voice data. In their study, the researchers used artificial intelligence (AI) to analyze and assess speech signals, where calculations are done and diagnoses made in seconds rather than hours.

One of the virtues of untethered soft robots is their ability to mechanically adapt to their surroundings and tasks. Now they are poised to become even more agile and controlled.

A researcher has created a computer reconstruction of a virus, including its complete native genome. Although other researchers have created similar reconstructions, this is believed to be the first to replicate the exact chemical and 3D structure of a 'live' virus.

For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.

Varroa destructor is an ectoparasitic mite that can cause European honey bee colonies to collapse by spreading Deformed wing virus as they feed. A study suggests a relatively small number of mites can contribute to a large number of infected bees.

The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study.

Crocodiles were mummified in a unique way at the Egyptian site of Qubbat al-Hawa during the 5th Century BC, according to a new study.

Research into how echidnas might respond to a warming climate has found clever techniques used by the animal to cope with heat, including blowing bubbles to wet its nose tip, with the moisture then evaporating and cooling its blood.

Until now, microscopic robotic systems have had to make do without arms. Now researchers have developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap particles.

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.
