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?

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.

Scientists have succeeded in synthesizing fumaric acid, a raw material for plastics, from CO2 powered by solar energy. Typically, fumaric acid is synthesized from petroleum as a raw material to make polybutylene succinate, a biodegradable plastic, but this research shows that it can be synthesized from CO2 and biomass-derived compounds using renewable energy.

Researchers have made a significant leap forward in developing insect-sized jumping robots capable of performing tasks in the small spaces often found in mechanical, agricultural and search-and-rescue settings. A new study demonstrates a series of click beetle-sized robots small enough to fit into tight spaces, powerful enough to maneuver over obstacles and fast enough to match an insect's rapid escape time.

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.

The natural abilities of squid tissues and the creativity of chemists combine to take hydrogel research in new directions.

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.

Researchers developed a faster and simpler way to model the forces needed to push, wiggle, and drill an object through soft, granular material in real-time. The methods could help engineers drive a rover over Martian soil, anchor a ship in rough seas, and walk a robot through sand and mud.

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.

First, they walked. Then, they saw the light. Now, miniature biological robots have gained a new trick: remote control. The hybrid 'eBiobots' are the first to combine soft materials, living muscle and microelectronics, said researchers.

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.

A study is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods -- a dinosaur group that includes both modern birds and their closest non-avian dinosaur relatives -- from the Chilean portion of Patagonia. The researchers' finds include giant megaraptors with large sickle-like claws and birds similar to todays ducks and geese.

Orangutans, mice, and horses are covered with it, but humans aren't. Why we have significantly less body hair than most other mammals has long remained a mystery. But a first-of-its-kind comparison of genetic codes from 62 animals is beginning to tell the story of how people -- and other mammals -- lost their locks.

What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.

Researchers took inspiration from ants to design a team of relatively simple robots that can work collectively to perform complex tasks using only a few basic parameters.

Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
