Bringing High-Resolution X-Ray Imaging to the Laboratory
Researchers have scaled down x-ray ptychography—a high-resolution imaging technique that used to require large, expensive facilities—for use in the lab. Read More »
So, You Think You Discovered a New State of Matter?
Take a step back and double check; don’t jump to thinking that unexpected data indicate something new. Read More »
Lighting Up Heart Cells with Tiny Lasers
A new microscopy technique that uses micrometer-sized lasers can track beating-induced changes in a heart cell’s refractive index. Read More »
How a Swirling Tail Helps Microbes Swim
A microswimmer that rotates its body and tail in opposite directions can propel itself in elastic, non-Newtonian fluids. Read More »
Active Particles Crystalize
Under the right conditions, self-propelled particles collectively transition from a state of liquid-gas coexistence to one where the particles can crystalize, according to simulations. Read More »
Finding Light in Dark Atomic Clouds
Researchers have prepared and manipulated subradiant states—in which collective effects slow down the decay of excited atoms—in a dense atomic cloud. Read More »
Black Holes Studied as a Population
The latest dataset from gravitational-wave observatories has enough events to allow researchers to study properties of the whole population of black holes. Read More »
Keeping Time on Entropy’s Dime
An experiment with a nanoscale clock verifies that a clock’s entropy per tick increases as the clock is made more precise. Read More »
Cloaking and Shielding Objects in a Fluid Flow
By injecting momentum into the fluid around an object, researchers can freely switch between obscuring the object’s presence and canceling hydrodynamic forces on it. Read More »
