How ultracold, superdense atoms become invisible
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli.....»»
Advanced microscopy technique offers a new look inside cells
Imagine tuning into a football game, but all of the players are invisible except for the two quarterbacks. Without being able to see the orchestrated movements of the full teams, this would be a very confusing game to watch......»»
Physicists track how continuous changes in dimensionality affect collective properties of a superfluid
An international research team from Innsbruck and Geneva has, for the first time, probed the dimensional crossover for ultracold quantum matter. In the regime between one and two dimensions, the quantum particles perceive their world as being 1D or 2.....»»
Atom interferometer charters Navy"s inertial navigation path to reduce drift
U.S. Naval Research Laboratory (NRL) researchers have developed a patent-pending Continuous 3D-Cooled Atom Beam Interferometer derived from a patented cold and continuous beam of atoms to explore atom-interferometry-based inertial measurement systems.....»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
Data gaps inhibit understanding of trans people"s experiences, researchers say
The influential book "Invisible Women" articulates some of the countless ways in which women are missing from the data we use to understand the world, including the testing of many drugs, consideration of how best to support refugees, and others. The.....»»
Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Samsung Music Frame hands-on: invisible audio done right
Samsung's Music Frame might look like a simple photo frame, but it's a real-deal wireless speaker too......»»
Physicists propose new way to search for dark matter: Small-scale solution could be key to solving large-scale mystery
Ever since its discovery, dark matter has remained invisible to scientists despite the launch of multiple ultra-sensitive particle detector experiments around the world over several decades......»»

Quantum dance to the beat of a drum: Researchers observe how energy of single electron is tuned by surrounding atoms
Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second......»»
Researchers devise new ways to engineer carbon-based semiconductors for electronics of the future
It might look like a roll of chicken wire, but this tiny cylinder of carbon atoms—too small to see with the naked eye—could one day be used for making electronic devices ranging from night vision goggles and motion detectors to more efficient sol.....»»
Classifying quantum secrets: Pendulum experiment reveals insights into topological materials
A recent study conducted at Tel Aviv University has devised a large mechanical system that operates under dynamical rules akin to those found in quantum systems. The dynamics of quantum systems, composed of microscopic particles like atoms or electro.....»»
