Phys.org / Why negativity can motivate founders: Study links doubts to greater persistence
A new study finds entrepreneurs become more committed to their business ventures when they are told they will fail, increasing their efforts to make those businesses successful. "Most entrepreneurs—people who start their ...
Phys.org / How the humble silkworm could help us discover new anti-aging treatments
When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long ...
Phys.org / Pekingese, Shih Tzu and Staffordshire bull terrier among 12 dog breeds at risk of serious breathing condition
Scientists have identified a further 12 dog breeds as being at risk of brachycephalic obstructive airway syndrome—a condition that can cause serious breathing problems—including the Pekingese, Shih Tzu, Boston terrier, ...
Phys.org / Rewriting our understanding of early hominin dispersal from Africa to Eurasia
What if Homo erectus (H. erectus), the direct ancestor of modern humans, arrived in China much earlier than we thought? Research published in Science Advances may rewrite our understanding of early human dispersal in that ...
Phys.org / Rising simultaneous wildfire risk compromises international firefighting efforts
The most high-risk conditions for fires are increasingly happening across countries at the same time, making resulting wildfires even more challenging to tackle, new research reveals.
Phys.org / Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Phys.org / Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics
A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation ...
Phys.org / The cooling system that lets bees beat the heat when hovering
To stay in the air when hovering over a flower, bumble bees continually flap their wings rapidly, a metabolic process that generates a massive amount of internal heat. Their flight muscles work so intensely that they can ...
Phys.org / New 'Mars GPS' lets Perseverance pinpoint its location within 25 centimeters
Imagine you're all alone, driving along in a rocky, unforgiving desert with no roads, no map, no GPS, and no more than one phone call a day for someone to inform you exactly where you are. That's what NASA's Perseverance ...
Phys.org / Araish spiral galaxy observations uncover a 26,700-light-year radio jet
An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / Archaeologists identify elders in Iron Age Israel through household artifacts
A new study from Bar-Ilan University is shedding light on a long-overlooked social group in archaeology: the elderly. While research on women and children has flourished in recent decades, older adults have remained largely ...
