University of South Australia researchers have drawn inspiration from a 300-million-year-old superior flying machine — the dragonfly — to show why future flapping wing drones will probably resemble the insect in shape, wings and gearing. A team of PhD students led by UniSA Professor of Sensor Systems, Javaan Chahl, spent part of the 2020 COVID-19 […]

The prospects for life on a given planet depend not only on where it forms but also how, according to Rice University scientists.Planets like Earth that orbit within a solar system’s Goldilocks zone, with conditions supporting liquid water and a rich atmosphere, are more likely to harbor life. As it turns out, how that planet […]

The use of multimode optical fibers to boost the information capacity of the Internet is severely hampered by distortions that occur during the transmission of images because of a phenomenon called modal crosstalk. However, University of Rochester researchers at the Institute of Optics have devised a novel technique, described in a paper in Nature Communications, […]

Astronomers have identified more than 4,000, and counting, confirmed exoplanets — planets orbiting stars other than the sun — but only a fraction have the potential to sustain life.Now, new research from UBC’s Okanagan campus is using the geology of early planet formation to help identify those that may be capable of supporting life. “The […]

Scientists have spotted the largest flare ever recorded from the sun’s nearest neighbor, the star Proxima Centauri.The research, which appeared in The Astrophysical Journal Letters, was led by the University of Colorado Boulder and could help to shape the hunt for life beyond Earth’s solar system.

How many Tyrannosaurus rexes roamed North America during the Cretaceous period? That’s a question Charles Marshall pestered his paleontologist colleagues with for years until he finally teamed up with his students to find an answer.What the team found, to be published in the journal Science, is that about 20,000 adult T. rexes probably lived at […]

Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 years by scientists from the CNRS, the Université Paris-Saclay and the National museum […]

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star may have lost its atmosphere but gained a second one through volcanic activity. The planet, GJ 1132 b, is hypothesized to have begun as a gaseous world with a thick hydrogen blanket of atmosphere. Starting out at several times […]

An atmosphere is what makes life on Earth’s surface possible, regulating our climate and sheltering us from damaging cosmic rays. But although telescopes have counted a growing number of rocky planets, scientists had thought most of their atmospheres long lost. However, a new study by University of Chicago and Stanford University researchers suggests a mechanism […]

We are made of stardust, the saying goes, and a pair of studies including University of Michigan research finds that may be more true than we previously thought. The first study, led by U-M researcher Jie (Jackie) Li and published in Science Advances, finds that most of the carbon on Earth was likely delivered from […]

A new study has found the first evidence of sophisticated breathing organs in 450-million-year-old sea creatures. Contrary to previous thought, trilobites were leg breathers, with structures resembling gills hanging off their thighs. Trilobites were a group of marine animals with half-moon-like heads that resembled horseshoe crabs, and they were wildly successful in terms of evolution. […]

The humble lab mouse has provided invaluable clues to understanding diseases ranging from cancer to diabetes to COVID-19. But when it comes to psychiatric conditions, the lab mouse has been sidelined, its rodent mind considered too different from that of humans to provide much insight into mental illness. A new study, however, shows there are […]

A single “super photon” made up of many thousands of individual light particles: About ten years ago, researchers at the University of Bonn produced such an extreme aggregate state for the first time and presented a completely new light source.
