Royal Ontario Museum announces the oldest swimming jellyfish in the fossil record with the newly named Burgessomedusa phasmiformis. This 505-million-year-old swimming jellyfish from the Burgess Shale highlights diversity in the Cambrian ecosystem.

Engineers have developed HADAR, or heat-assisted detection and ranging.

An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the structure of neutral mutations and the evolution of organisms.

Researchers have revealed the unique 'cheating' strategy a New Zealand insect has developed to avoid being eaten -- mimicking a highly toxic species.

Scientists found that trout from lakes stocked decades ago in the Wind River Mountains have higher numbers of gill rakers, which are bony or cartilage structures in the gullets of fish that act as sieves to retain zooplankton and nourish the trout. The difference is likely a result of the trout adapting to the food sources of the once-fishless high-mountain lakes -- a change that has taken place in a relatively short period of time and at a rate that is generally consistent with the historic timing of stocking for each of the lakes.

Engineers have designed a new, shape-shifting display that can fit on a card table and allows users to draw 3D designs and more.

The origin of bees is tens of millions of years older than most previous estimates, a new study shows. A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today's continents of Africa and South America.

Scientists showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit.

A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.

This soft robotic gripper is not only 3D printed in one print, it also doesn't need any electronics to work.

Researchers have developed an L3 F-TOUCH sensor to enhance tactile capabilities in robots, allowing it to 'feel' objects and adjust its grip accordingly.

Bees and wasps have converged on the same architectural solutions to nest-building problems, according to new research.

A new study of the strain of influenza A responsible for the 2009 H1N1 pandemic -- pdm09 -- shows that the virus has passed from humans to swine about 370 times since 2009, and subsequent circulation in swine has resulted in the evolution of pdm09 variants that then jumped from swine to humans.

A new machine-learning technique can efficiently learn to control a robot, leading to better performance with fewer data.

Inspired by the effortless way humans handle objects without seeing them, engineers have developed a new approach that enables a robotic hand to rotate objects solely through touch, without relying on vision.

Researchers have described a new species of armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.

As artificial intelligence expands across more professions, robot preachers and AI programs offer new means of sharing religious beliefs, but they may undermine credibility and reduce donations for religious groups that rely on them.

Scientists have developed a suite of robotic systems and planners enabling robots to explore more quickly, probe the darkest corners of unknown environments, and create more accurate and detailed maps. The systems allow robots to do all this autonomously, finding their way and creating a map without human intervention.
