Money matters to happiness–perhaps more than previously thought — ScienceDaily

What’s the relationship between money and well-being? “It’s one of the most studied questions in my field,” says Matthew Killingsworth, a senior fellow at Penn’s Wharton School who studies human happiness. “I’m very curious about it. Other scientists are curious about it. Laypeople are curious about it. It’s something everyone is navigating all the time.” […]

New electron microscopy technique offers first look at previously hidden processes

The chemical process is set to transform the future of clean water and […]

Water on Mars not as widespread as previously thought — ScienceDaily

Water on Mars, in the form of brines, may not be as widespread as previously thought, according to a new study by researchers at the Arkansas Center for Space and Planetary Sciences. Researchers combined data on brine evaporation rates, collected through experiments at the center’s Mars simulation chamber, with a global weather circulation model of […]

Newton’s Principia may have been more popular than previously thought

Isaac Newton’s 17th century book, the Principia, gave the famed English scientist a reputation: “[T]here goes the man that writt a book that neither he nor any body else understands,” a Cambridge student is said to have remarked as Newton passed by one day. Likewise, historians have assumed that only a select few scientists and […]

Ancient Egyptian temple reveals previously unknown star constellations

The restoration of a soot-filled ancient Egyptian temple has revealed the previously unknown names of ancient Egyptian constellations, according to experts in Germany and Egypt. The restoration has also uncovered the gorgeous original colors the ancient Egyptians painted the 2,000-year-old temple. As workers in Egypt remove soot and dirt from the temple, sometimes with a […]

Accuracy of rapid COVID test may be lower than previously suggested

The accuracy of a rapid finger-prick antibody test for SARS-CoV-2, the virus responsible for covid-19 infection, may be considerably lower than previously suggested, finds a study published by The BMJ. The results suggest that if 10% of people given the test had previously been infected, around 1 in 5 positive test results would be incorrect […]

Researchers demonstrate a superconductor previously thought impossible

Polarized light images show researchers how electrons, represented by red crosses, in their test samples behave under different circumstances. Credit: © 2020 Okazaki et al. Superconductivity is a phenomenon in which an electric circuit loses its resistance and becomes extremely efficient under certain conditions. There are different ways in which this can happen, which were […]
