Read MoreElectrons are great. We use them to move vehicles, illuminate cities, and, of course, compute. But computation is not confined to the world of electronics. And shifting to alternative nonelectronic realms can unlock unique advantages: Photonic chips, for instance, process information with light while generating little heat. Another compelling alternative is fluidics, which uses pressurized…
A newly discovered raptor-like dinosaur from Patagonia is changing how scientists think about ancient predators. Named Kank australis, the 70-million-year-old dinosaur appears to have hunted fish much like modern herons, using a long, flexible neck and specialized vertebrae adapted for swift, precise movements.
Scientists have discovered Labrujasuchus expectatus, a bizarre crocodile relative that looked more like an ostrich-like dinosaur than anything resembling a modern crocodile. It walked on two legs, had tiny arms, and sported a toothless beak—an unexpected combination for a member of the crocodile lineage.
Emerald PANAMA CITY, PANAMA—Phys.org reports that X-ray fluorescence, infrared spectroscopy, and photoluminescence have been used to confirm that five green stones found at two archaeological sites on Panama’s Pacific coastline are emeralds that were mined in Colombia more than 1,000 years ago. The emeralds were recovered from elite burials in the Gran Coclé region, at…

The hoard of jewelry was found in a ceramic jar. RIYADH, SAUDI ARABIA—A collection of more than 100 gold, silver, and gemstone jewelry pieces stored in a ceramic jar was discovered in Diriyah, a settlement that was once a stop on the route that connected Basra in southern Iraq and Mecca on the west coast…
A practical introduction to phase noise concepts, explaining how oscillator instability affects RF systems and how phase noise is measured, analyzed, and reported.What Attendees will LearnWhat phase noise is and why it matters — Learn how real-world oscillators differ from ideal ones, why short-term frequency instability arises, and why phase variations typically have a much…
I have been an application-specific IC (ASIC) designer for almost three decades. Over that time, I’ve moved through the full academic trajectory, from graduate student to full professor; later, I transitioned to industry after an unsuccessful stint at entrepreneurship. When I made the switch to the private sector in 2019, I began focusing on a…
