New visual scale offers simple measure to help identify job burnout — ScienceDaily
“Job burnout” is a term that’s far too familiar to many people. A 2020 Gallup poll showed that 76 percent of employed Americans surveyed have experienced burnout. Perhaps due to the condition’s prevalence, the World Health Organization recently reclassified burnout in its International Classification of Diseases as an occupational syndrome resulting from “chronic workplace stress…

Gold from ancient Troy, Poliochni and Ur had the same origin | HeritageDaily
Scientists, using an innovative mobile laser method have determined that gold found in ancient Troy, Poliochni and Ur had the same origin. Researchers from several institutions, led by Ernst Pernicka, scientific director of the Curt-Engelhorn Center for Archaeometry (CEZA) at the Reiss-Engelhorn Museums in Mannheim and director of the University of Tübingen’s Troy project, applied…

How voice technology influences what we reveal about ourselves — ScienceDaily
Researchers from University of Miami and New York University published a new Journal of Marketing article that examines how voice technology can affect what consumers reveal about themselves. The study, forthcoming in the Journal of Marketing, is titled “Information Disclosure in the Era of Voice Technology” and is authored by Johann Melzner, Andrea Bonezzi, and…

New Pixel Sensors Bring Their Own Compute
By giving compute powers to atomically thin versions of the CMOS sensors now found in most digital cameras, a prototype sensor array can capture images using thousands to millions of times less power, a new study finds. CMOS sensors are a kind of active pixel sensor, which combine a light detector with one or more…

Mammoths may have gone extinct much earlier than DNA suggests
Some ancient DNA may be leading paleontologists astray in attempts to date when woolly mammoths and woolly rhinos went extinct. In 2021, an analysis of plant and animal DNA from sediment samples from the Arctic, spanning about the last 50,000 years, suggested that mammoths survived in north-central Siberia as late as about 3,900 years ago…

John Bardeen’s Terrific Transistorized Music Box
On 16 December 1947, after months of work and refinement, the Bell Labs physicists John Bardeen and Walter Brattain completed their critical experiment proving the effectiveness of the point-contact transistor. Six months later, Bell Labs gave a demonstration to officials from the U.S. military, who chose not to classify the technology because of its potentially…

Do voluntary corporate pledges help reduce plastic pollution? — ScienceDaily
Earth is awash in plastic. It litters our landscapes and waterways, overflows landfills and increasingly threatens human and environmental health worldwide. And because most plastic is made from fossil fuels, it also contributes to climate change. Many companies, mindful of growing public expectations about corporate responsibility, have pledged to reduce their plastic footprints. However, a…

In 2017, Badlands Dinosaur Museum crew member Jack Wilson spotted the remains of what turned out to be a new species of tyrannosaur, named Daspletosaurus wilsoni, or D. wilsoni. Wilson first saw a small, flat piece of bone projecting out…
