A team of researchers from the United States and the United Kingdom has created nanoporous tripeptide crystals that directly convert evaporation energy into mechanical motion. “We essentially created a new type of actuator, which is driven by water evaporation,” said first author Roxana Piotrowska, a Ph.D. student in the Advanced Science Research Center at the [...]
Archaeologists have unearthed the well-preserved remains of a 2,700-year-old wine press at the Phoenician site of Tell el-Burak, 9 km south of Sidon in present-day Lebanon. The ruins of Tell el-Burak, a small Phoenician settlement dating from the last quarter of the 8th to the middle of the 4th century BCE, were discovered in 2001. [...]
The whale shark (Rhincodon typus) is the world’s largest fish, growing to maximum known sizes of 18 m (59 feet) total length. A new study led by University of Western Australia marine biologists has found that male whale sharks grow quickly, before plateauing at an average adult length of about 8-9 m (26.2-29.5 feet), and [...]
Using NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based telescopes, astronomers have discovered a Jupiter-sized planet orbiting a nearby white dwarf star called WD 1856+534. The WD 1856+534 system, also known as TIC 267574918 and LP 141-14, is located about 80 light-years away in the constellation of Draco. The white dwarf is the remnant [...]
Human white blood cells, or leukocytes, swim using a newly-described mechanism called molecular paddling, according to new research led by University Grenoble Alpes and Aix Marseille University. Cells have evolved different strategies to migrate and explore their environment. For example, sperm cells, microalgae, and bacteria can swim through shape deformations or by using a whip-like [...]
An international team of researchers has now found that computerized training can support preterm children's academic success. In their randomized controlled study 'Fit for School', the researchers compared two learning apps.
Determining whether high-intensity interval training (HIIT) is an appropriate form of exercise for the average person has been hotly debated for years. But for one researcher, there's not much to debate -- interval exercise, when used appropriately, can fit into people's menu of flexible exercise options.
Early to bed, early to rise ... while the old saying promises health, wealth and wisdom, new research confirms part of the adage holds true, as a world first study shows that people who go to bed early are more likely to be in better health and more physically active compared to night owls.
Confuciusornis was a crow-like fossil bird that lived in the Cretaceous ~120 million years ago. It was one of the first birds to evolve a beak. Early beak evolution remains understudied. Using an imaging technique called Laser-Stimulated Fluorescence, researchers address this by revealing just how different the beak and jaw of Confuciusornis were compared to birds we see today.
Researchers have found a way to send tiny, soft robots into humans, potentially opening the door for less invasive surgeries and ways to deliver treatments for conditions ranging from colon polyps to stomach cancer to aortic artery blockages.
Not all rats like to be tickled but by listening to their vocalizations it is possible to understand in real-time their individual emotional response. The study suggests that if this same relationship is observed for other situations, then it may be possible to use call patterns in rats to measure their emotional response and understand how best to improve their welfare.
Scientists used three-dimensional computer modelling to investigate the hindlimb of Euparkeria capensis -- a small reptile that lived in the Triassic Period 245 million years ago -- and inferred that it had a 'mosaic' of functions in locomotion.
Researchers want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now the researchers advocate paying more attention to the classic zeolites. These, they assert, would even have the potential to make a bioeconomy based on renewable resources possible.
