Blowin’ in the Galactic Wind
Nuclear winds expel cold molecular hydrogen gas from the Galactic Center, providing new clues to how star-forming material circulates through the Galaxy. Continue reading
Quantum Measurement Strikes a Balance
An experiment demonstrates the trade-off between measurement and total information content—comprising gain, disturbance, and reversibility—in a quantum system. Continue reading
Predicting the Shape of Pointy-Rock Forests
The shape and curvature evolution of dissolving rocks can be predicted using a new theory. Continue reading
Identifying the Source of a Sound
Torben Pastore had careers in rock n’ roll, furniture design, and construction before beginning a research career in psychoacoustics. Now he investigates how humans perceive their acoustical surroundings. Continue reading
Ultrasound Imaging of Brain with Machine Learning
A proposed machine-learning technique can convert ultrasound signals into a skull profile, which could lead to noninvasive imaging for medical treatments in the human brain. Read more in APS Physics…
Laser Breaks Liquid into Uniform Droplets
A laser beam hitting a column of liquid controls the droplet pinch-off at the bottom of the stream. Continue reading
Mobile Phone Signals Hold Real-Time Rainfall Information
Techniques for monitoring rainfall with signals from mobile phone networks are making their way to small-scale farmers in rural Africa. Continue reading
A Physical Match for the Riemann Zeta Function
Mathematical properties of a famous number-theory conjecture correspond to the physical scattering properties of a quantum field theory. Continue reading
Glassy Behavior Depends on Dimension
The number of excess vibrational modes in glasses scales differently in two dimensions than it does in three. Continue reading
Search for Sculptor’s Stone Reveals New Marble Outcrops
