(Phys.org)—Three teams working independently have found a nearly identical way to boost the resolution of quantum magnetic sensors, allowing frequency measurements with far higher precision than previous techniques. Two teams, one with ETH Zurich, the other based at Ulm University in Germany, have published their results in the journal Science. Show More Summary
Not so long ago, people like my Aunt Muriel thought of sunburn as a necessary evil on the way to a "good base tan." She used to slather on the baby oil while using a large reflector to bake away. Aunt Muriel's mantra when the inevitable burn and peel appeared: Beauty has its price.
Our computers, even the fastest ones, seem unable to withstand the needs of the enormous quantity of data produced in our technological society. That's why scientists are working on computers using quantum physics, or quantum computers, which promise to be faster and more powerful than conventional computers.
A technology originally developed to smooth out and pattern high-powered laser beams for the National Ignition Facility (NIF) can be used to 3-D print metal objects faster than ever before, according to a new study by Lawrence Livermore researchers.
Scientists from the Netherlands and Russia have designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant strips arranged periodically. Show More Summary
Quantum computers are experimental devices that offer large speedups on some computational problems. One promising approach to building them involves harnessing nanometer-scale atomic defects in diamond materials.
So, this is what the early stage of the graphic short story laying out process looks like. For me. I actually do it old school with pencil and paper, and actual laying out. You can click for a larger view but I've blurred out some bits - because spoilers. So...20 pages works nicely. Show More Summary
Well, that was fun. And the NPR West studios in Culver City are fantastic. I'll let you know when the piece, about science consulting for the entertainment industry, appears. Unless I really made a pig's ear of the interview in which case I may well forget to post it. ;) -cvj Click to continue reading this post ? The post At NPR West appeared first on Asymptotia.
Well, yesterday evening and today I've got an entirely different hat - SF short story writer! First let me apologize for faking it to all my friends reading who are proper short story writers with membership cards and so on. Let me go...Show More Summary

Today's selection of need-to-know updates from the world of physics
During my sabbatical last year, I decided to try to do a photo-a-day project, taking and sharing at least one good picture a day of something or another. The strict photo-a-day format fell victim to my general busy-ness and disorganization, but I did eventually complete the whole thing. In the final post of the series,…
When a ballerina pirouettes, twirling a full revolution, she looks just as she did when she started. But for electrons and other subatomic particles, which follow the rules of quantum theory, that's not necessarily so. When an electron moves around a closed path, ending up where it began, its physical state may or may not be the same as when it left.
If you've shaken a snow globe, you've enjoyed watching its tiny particles slowly sink to the bottom. But do all small objects drift the same way and at the same pace?
A research team led by Professor YongKeun Park of the Physics Department at KAIST has developed an optical manipulation technique that can freely control the position, orientation, and shape of microscopic samples having complex shapes. The study has been published online in Nature Communications on May 22.
(Phys.org)—A team at Harvard University has found a way to create a cold-atom Fermi–Hubbard antiferromagnet, which offers new insight into how electrons behave in solids. In their paper published in the journal Nature, the group describes...Show More Summary
The quantum world is both elegant and mysterious. It is a sphere of existence where the laws of physics experienced in everyday life are broken—particles can exist in two places at once, they can react to each other over vast distances, and they themselves seem confused over whether they are particles or waves.

At first glance, biomedical imaging devices, cell phones, and radio telescopes may not seem to have much in common, but they are all examples of technologies that can benefit from certain types of relaxor ferroelectrics—ceramics that change their shape under the application of an electric field.
