Tiny magnetic DNA particles protect olive oil from counterfeiters
Who guarantees that expensive olive oil isn't counterfeit or adulterated? An invisible label, developed by ETH Zurich researchers, could perform this task. The tag consists of tiny magnetic DNA particles ...
Research splits alligator snapping turtle, 'dinosaur of the turtle world,' into three species
The alligator snapping turtle is the largest river turtle in North America, weighing in at up to 200 pounds and living almost a century. Now researchers from Florida and the University of Vermont have discovered ...
How a plant beckons the bacteria that will do it harm
A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix.
Your T-shirt's ringing: Telecommunications in the spaser age
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
Bake your own droplet lens
A droplet of clear liquid can bend light, acting as a lens. Now, by exploiting this well-known phenomenon, researchers have developed a new process to create inexpensive high quality lenses that will cost ...
Computer algorithm outperforms humans on 'Labeled Faces in the Wild' benchmark
Physicists use magnetism simulation software to model US presidential elections
How do liquid foams block sound?
Liquid foams have a remarkable property: they completely block the transmission of sound over a wide range of frequencies. CNRS physicists working in collaboration with teams from Paris Diderot and Rennes ...
Microgel-based thermoresponsive membranes for water filtration
(Phys.org) —Filtration using membrane filters is one of the most commonly used separation techniques. Modern developments are aimed at membranes with tailored separation properties as well as switchability. ...
Probing the sound of a quantum dot
(Phys.org) —Physicists at the University of Sydney have discovered a method of using microwaves to probe the sounds of a quantum dot, a promising platform for building a quantum computer.
Medieval bishop's theory resembles modern concept of multiple universes
A 13th century bishop's theory about the formation of the universe has intriguing parallels with the theory of multiple universes. This was uncovered by the the Ordered Universe project at Durham University, ...
Fundamental research in phonon scattering helps scientists design graphene materials for applications
Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material—strong, light, nearly transparent and an excellent conductor of electricity and heat—and it very well ...
Nest-building in finches is a learning process developed through experience
(Phys.org) —Nest-building is not just an innate skill but a learning process that birds develop through experience, research suggests.
