| What do soap bubbles and butterflies have in common? Posted: 08 Apr 2020 12:12 PM PDT A unique butterfly breeding experiment gave researchers an opportunity to study the physical and genetic changes underlying the evolution of structural color, responsible for butterflies' iridescent purples, blues and greens. Using helium ion microscopy, the scientists discovered that a 75 percent increase in thickness of the chitin lamina of wing scales turned iridescent gold to shiny blue. They showed that knocking out a gene called optix achieves the same result: a bluer Common Buckeye. |
| New fossil from Brazil hints at the origins of the mysterious tanystropheid reptiles Posted: 08 Apr 2020 11:27 AM PDT A new species of Triassic reptile from Brazil is a close cousin of a mysterious group called tanystropheids. |
| Belle II yields first results in search of the Z' boson Posted: 08 Apr 2020 10:32 AM PDT The Belle II experiment started about one year ago. The work deals with a new particle in the context of dark matter, which accounts for about 25 percent of the universe. |
| New info on interstellar magnetic field in solar neighborhood Posted: 08 Apr 2020 08:32 AM PDT An international research team has mapped the interstellar magnetic field structure and interstellar matter distribution in the solar neighborhood. |
| Harnessing the power of electricity-producing bacteria for programmable 'biohybrids' Posted: 08 Apr 2020 08:32 AM PDT Someday, microbial cyborgs -- bacteria combined with electronic devices -- could be useful in fuel cells, biosensors and bioreactors. But first, scientists need to develop materials that not only nurture the microbes, but also efficiently and controllably harvest the electricity or other resources they make. Now, researchers have developed one such material that enabled them to create a programmable 'biohybrid' system that conducts electrons from electricity-producing (exoelectrogenic) bacteria. |
| New 'refrigerator' super-cools molecules to nanokelvin temperatures Posted: 08 Apr 2020 08:32 AM PDT Physicists have found a way to cool molecules of sodium lithium down to 200 billionths of a Kelvin, just a hair above absolute zero. They did so by applying a technique called collisional cooling, in which they immersed molecules of cold sodium lithium in a cloud of even colder sodium atoms. The ultracold atoms acted as a refrigerant to cool the molecules even further. |
| Revolutionary light-emitting silicon Posted: 08 Apr 2020 08:32 AM PDT Emitting light from silicon has been the 'Holy Grail' in the microelectronics industry for decades. Solving this puzzle would revolutionize computing, as chips will become faster than ever. Researchers have now succeeded: they have developed an alloy with silicon that can emit light. The team will now start creating a silicon laser to be integrated into current chips. |
