Physicists Turn a Single Frozen Atom into a Camera That Sees Light Below the Diffraction Limit
1+ day, 18+ hour ago (568+ words) Conceptual illustration of the Atom Camera. A single ultracold rubidium (Rb) atom trapped in an optical tweezer is spatially scanned to visualize the intensity and polarization distributions of a light pattern. That is the gist of a technique a Japanese…...
The Brain Circuit That Decides Where One Memory Ends and the Next Begins
2+ day, 9+ hour ago (553+ words) That circuit normally does the opposite. Its job is to keep memories that should stay apart from bleeding into one another, and a team at the University of California, Los Angeles has now traced exactly how it works. For decades…...
A Contraceptive Drug May Help Reverse Nerve Damage Once Thought Permanent
2+ day, 16+ hour ago (24+ words) The muscle cluster flinched. Not a twitch caused by direct stimulation, but a contraction driven by signals travelling along axons that had grown, over...
The Sun Is Squeezing Its Magnetic Activity Toward the Surface and Nobody Knows Why
2+ day, 16+ hour ago (25+ words) Six telescopes, spread across three continents, have been listening to the Sun for nearly four decades. Not to its light. To its sound. The Birmingham...
Young Children Can Read Human Eyes for Hidden Desires. A Robot's Gaze Tells Them Nothing.
2+ day, 16+ hour ago (28+ words) By the age of 3, a child already knows something that took engineers years to articulate: the eyes are not just organs of vision. They are organs of...
A Tiny Drug-Loaded Mesh Implanted in the Brain Is Keeping Glioblastoma at Bay
2+ day, 16+ hour ago (25+ words) It's smaller than a thumbnail. A dense, whitish square, barely a millimetre thick, laser-cut from a folded membrane of polymer fibres thinner than human...

Dead Stars Are Sculpting the Cradles Where New Ones Are Born
2+ day, 17+ hour ago (23+ words) Point a submillimetre telescope at almost any region of active star formation and you'll notice the same odd geometry. Gas doesn't collapse inward...
Quantum Physicists Have Generated the First Mathematically Certified Perfect Random Numbers
3+ day, 13+ hour ago (29+ words) Randomness sounds like the easiest thing in the world to produce. Flip a coin, roll a die, pick a number between one and a hundred. But there is a...
