2+ hour, 34+ min ago  (37+ words) A marine biologist studying the photophores of a bioluminescent fish species found needle-shaped guanine crystals that scatter and redirect light instead of merely reflecting it, a discovery that could inspire more efficient biomedical and optical devices....

4+ week, 1+ day ago  (625+ words) If you've ever wondered how geologists know so much about ancient beaches and shallow oceans " from the paleoenvironment to the animals roaming around, the seasonality of the weather, and even the time of day when the ancient scene was preserved…...

3+ mon, 3+ week ago  (320+ words) By using gold nanospheres engineered to capture light across the solar spectrum, researchers at Korea University took a step toward lowering barriers to more efficient and cost-effective renewable energy harvesting. Hun Rho et al. introduce plasmonic colloidal supraballs " solution-processable assemblies…...

3+ mon, 4+ week ago  (561+ words) A new analysis of archival data from the Near Infrared Mapping Spectrometer (NIMS) on board NASA's Galileo spacecraft has revealed the first evidence of ammonia-bearing compounds on Jupiter's icy moon Europa, offering new clues about its subsurface ocean and recent…...

5+ mon, 4+ day ago  (487+ words) Scientists have long known that fluid inclusions in halite crystals contain samples of the early Earth's atmosphere. But teasing accurate measurements out of those inclusions has proven to be a formidable challenge: they contain both air bubbles and brine, and…...

7+ mon, 1+ week ago  (579+ words) Scientists have demonstrated that supercompressed water transforms into ice VI at room temperature through multiple freezing-melting pathways, which occur via a previously unknown form of metastable ice, named ice XXI. A small crystal of ice XXI formed through nucleation and slow…...

8+ mon, 4+ day ago  (360+ words) Ice at minus 10 degrees Celsius releases more iron from common minerals than liquid water at 4 degrees Celsius, according to a team of researchers from Ume" University, the Institut des Sciences Chimiques de Rennes and CNRS. This discovery could help explain…...
