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.

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.

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.

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.

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.

The movement of people across the Bering Sea from North Asia to North America is a well-known phenomenon in early human history. Nevertheless, the genetic makeup of the  people who lived in North Asia during this time has remained mysterious due to a limited number of ancient genomes analyzed from this region. Now, researchers describe genomes from ten individuals up to 7,500 years old that help to fill the gap and show geneflow from people moving in the opposite direction from North America to North Asia.

A new study posits that interstellar cloud conditions may have played a significant role on the presence of key building blocks of life in the solar system.

Only a fraction of the 7,000 to 8,000 languages spoken around the world benefit from modern language technologies like voice-to-text transcription, automatic captioning, instantaneous translation and voice recognition. Researchers want to expand the number of languages with automatic speech recognition tools available to them from around 200 to potentially 2,000.

A new study based on 297 ancient Scandinavian genomes analysed together with the genomic data of 16,638 present day Scandinavians resolve the complex relations between geography, ancestry, and gene flow in Scandinavia -- encompassing the Roman Age, the Viking Age and later periods. A surprising increase of variation during the Viking period indicates that gene flow into Scandinavia was especially intense during this period.

The artificial intelligence algorithms behind the chatbot program ChatGPT -- which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries -- might one day be able to help doctors detect Alzheimer's Disease in its early stages. Research recently demonstrated that OpenAI's GPT-3 program can identify clues from spontaneous speech that are 80% accurate in predicting the early stages of dementia.

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.
