An international research team has determined that Troodon, a dinosaur very close to modern birds, was a warm-blooded animal (an endotherm), but had a reproductive system similar to that of modern reptiles. The scientists applied a new method which allowed for accurate determination of the temperature when the egg's carbonate shell was formed. Furthermore, the researchers showed that Troodon laid 4 to 6 eggs per clutch. As nests with up to 24 Troodon eggs had been found, the scientists conclude that several Troodon females laid their eggs in communal nests.

A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.

In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.

Newly created soft-rigid robotic fingers incorporate powerful sensors along their entire length, enabling them to produce a robotic hand that could accurately identify objects after only one grasp.

Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.

Student researchers investigate how intentional robot deception affects trust, examining the effectiveness of apologies after robots lie.

A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.

Artificial intelligence technologies like ChatGPT are seemingly doing everything these days: writing code, composing music, and even creating images so realistic you'll think they were taken by professional photographers. Add thinking and responding like a human to the conga line of capabilities. A recent study proves that artificial intelligence can respond to complex survey questions just like a real human.

Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.

Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.

New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.

Even supposedly adaptable mammal species face increased risk of extinction.

Researchers found that preschoolers prefer learning from what they perceive as a competent robot over an incompetent human. This study is the first to use both a human speaker and a robot to see if children deem social affiliation and similarity more important than competency when choosing which source to trust and learn from.

With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.

When the Kinks' Ray Davies penned the tune 'Last of the Steam-Powered Trains,' the vanishing locomotives stood as nostalgic symbols of a simpler English life. But for a paleontologist, the replacement of steam-powered trains with diesel and electric engines, as well as cars and trucks, might be a model of how some species in the fossil record died out.

While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.

At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.

Engineers are harnessing artificial intelligence (AI) and wireless technology to unobtrusively monitor elderly people in their living spaces and provide early detection of emerging health problems.

Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
