Phys.org / Scientists strike invisible gold in the deep sea—locked inside fool's gold
Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers ...
Phys.org / Dead stars in our cosmic backyard: Astronomers spot four white dwarfs hiding under our noses
Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are ...
Phys.org / Study links sea level to Earth's carbon thermostat
Earth has a natural thermostat that has kept the planet habitable for more than 100 million years. Scientists have struggled to fully explain how it works, but new research identifies a missing link between phosphate availability ...
Phys.org / As super El Niño draws global attention, the Indian Ocean may hold the key to Mediterranean climate extremes
As scientists around the world closely monitor the possible development of a powerful "Super El Niño," a new study suggests that another tropical ocean deserves equal attention. Researchers have found that temperature changes ...
Phys.org / Atoms tell different stories when light hits a molecule in trillionths of a second
Researchers have captured how a molecule redistributes energy after absorbing light, differentiating the roles of individual atoms in the process. They used X-ray flashes from the European XFEL to show that different atoms ...
Phys.org / Hidden in Maya wall writings: A named astronomer emerges from 1,200-year-old calculations
Researchers have reconstructed and transcribed a mathematical formula from the site of Xultun, Guatemala, revealing the name of a Maya astronomer for the first time. During the Classic period (250–900 CE), mathematics and ...
Phys.org / World's first superconducting quantum heat engine offers path to larger quantum computers
Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a boost to quantum technology, and a clearer picture of quantum thermodynamics could in turn enhance our ...
Phys.org / Hubble discovers first of star cluster's missing black holes
The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data ...
Phys.org / 'Silly sprinklers' put in reverse to further unravel decades-old physics puzzle
Each summer, lawns are marked by a familiar addition: "silly sprinklers," whose loops and spirals spew water in creative ways. While seemingly frivolous in their construction, a team of mathematicians has used their design ...
Phys.org / Typhoons mix up bacteria and biochemistry
After a typhoon surprised a research cruise, scientists took advantage of the unique sampling opportunity to reveal rapid changes in bacterioplankton communities and biogeochemical cycling.
Phys.org / Zirconium tweak unlocks stronger cast aluminum alloy with ductility boost
Researchers at the Department of Materials Engineering (MatE), Indian Institute of Science (IISc), and collaborators have developed a new lightweight cast aluminum alloy that is both exceptionally strong and remarkably ductile, ...
Phys.org / Invasive aoudad pose deadly risk to native bighorn sheep
An invasive species found across West Texas may pose a greater threat to native bighorn sheep than previously understood.
