We might imagine that electric current flows as a smooth, even stream of electrons through our electronics devices, but at the quantum scale the flow of electric current might be more accurately pictured as a bubbling brook ...
(Phys.org)—As the saying goes, no two fingerprints are alike, and the same is true for quantum fingerprints. Just as a human fingerprint is only a fraction of the size of a person, yet can be used to distinguish between ...
(Phys.org) —If you're in the business of cracking codes, it would be pretty difficult to break into a security system that you don't even know is there. That's one of the advantages of molecular keypad locks, whose small ...
(Phys.org) —While most people know that using a cell phone means that the phone's location is being recorded, a new study has revealed just how little information is required to determine an individual's personal identity. ...
The unusual behavior of sulfur in Venus' atmosphere cannot be explained by an "aerial" form of extra-terrestrial life, according to a new study.

(Phys.org) —A team of researchers working at Hanyang University in Korea has developed a new type of polymer that can be used to map sweat droplets in the fingertips—possibly adding a new tool for forensics use. In their ...
Fingerprints—those swirling residues left on keyboards and doorknobs—are mostly invisible. They can affirm your onetime presence, but they cannot be used to track your day-to-day activities.

(Phys.org)—A secret agent is racing against time. He knows a bomb is nearby. He rounds a corner, spots a pile of suspicious boxes in the alleyway, and pulls out his cell phone. As he scans it over the packages, their contents ...
