Topology and entanglement are two powerful principles for characterizing the structure of complex quantum states.
Fermilab successfully demonstrates new technique to improve particle beams
Scientists at America's premier accelerator laboratory have successfully used a new technique, called optical stochastic cooling, to cool a particle beam and make it denser. The new method may enable future experiments to create more particle collisions. Denser particle beams provide researchers a better chance of exploring rare physics phenomena that help us understand our universe.

Detectan colision galactica desde Gemini Norte
Una nueva imagen capturada por el telescopio Gemini Norte, en Hawai'i, registra un par de galaxias espirales chocando entre si y comenzando un proceso de fusion a 60 millones de anos luz de distancia. Se trata de NGC 4568 y de NGC 4567, dos galaxias que estan enlazadas por sus campos gravitatorios y que finalmente se uniran para formar una inmensa galaxia eliptica en 500 millones de anos mas. La imagen tambien revela los vestigios de una supernova que fue detectada en 2020.
Do 'bouncing universes' have a beginning?
Some cosmological models propose that the universe expands and contracts in infinite cycles, but new research finds a crucial flaw in the latest version of this theory.
Robotic motion in curved space defies standard laws of physics
When bodies exist in curved spaces, it turns out that they can in fact move without pushing against something.
Body Posture Affects How Oral Drugs Absorbed by Stomach
A common method of administering drugs is orally, by swallowing a pill or capsule. But oral administration is the most complex way for the human body to absorb an active pharmaceutical ingredient, because the bioavailability of the drug in the gastrointestinal tract depends on the medication's ingredients and the stomach's dynamic physiological environment. In Physics of Fluids, researchers from employ a biomimetic in-silico simulator based on the realistic anatomy and morphology of the stomach - a "StomachSim" - to investigate and quantify the effect of body posture and stomach motility on drug bioavailability.
Ultrasound Could Save Racehorses from Bucked Shins
When racehorses enter training at about 2 years old, they can develop tiny stress fractures and new bone formations in their legs. This condition, called bucked shin, occurs in about 70% of the animals. In The Journal of the Acoustical Society of America, researchers have developed a method to screen for bucked shin using ultrasound. Axial transmission, in which an ultrasound emitter and receiver are placed on the skin to induce and measure wave velocities, is frequently used to study osteoporosis in humans. The method could detect bucked shin more easily and preserve the health and growth of young horses.
Human-Machine Interfaces Work Underwater, Generate Their Own Power
In Applied Physics Reviews, scientists at UCLA describe their development of a type of wearable human-machine interface device that is stretchable, inexpensive, and waterproof. The device is based on a soft magnetoelastic sensor array that converts mechanical pressure from the press of a finger into an electrical signal. The device involves two main components: a layer that translates mechanical movement to a magnetic response and a magnetic induction layer consisting of patterned liquid metal coils.
Jaime Marian: Then and Now / 2012 Early Career Award Winner
Jaime Marian is a professor at UCLA in the Department of Materials Science and Engineering, studying irradiation to develop materials and improve fusion reactor designs.
Journal of Mathematical Physics Announces 2021 Young Researcher Award
The Journal of Mathematical Physics has recognized Sam Collingbourne as the winner of its 2021 Young Researcher Award. His work on the stability properties of space-times in high dimensions culminated in the winning publication, "The Gregory-Laflamme instability of the Schwarzschild black string exterior." The judges selected Collingbourne from a pool of JMP authors and the prize includes $3,000. Collingbourne explores solutions to the Einstein equation, which relates the curvature and geometry of space-time to the matter content in space-time.
How bat brains listen out for incoming signals during echolocation
Bats famously have an ultrasonic navigation system: they use their extremely sensitive hearing to orient themselves by emitting ultrasonic sounds and using the echoes that result to build up a picture of their environment.
Machine Learning Reveals Hidden Components of X-Ray Pulses
Ultrafast pulses from X-ray lasers reveal how atoms move at femtosecond timescales, but measuring the properties of the pulses is challenging. A new approach trains neural networks to analyze the pulses. Starting from low-resolution measurements, the neural networks reveal finer details with each pulse, and they can analyze pulses millions of times faster than previous methods.

Low Pressure, High Stakes: UNLV Physicists Make Major Gains in Race for Room-Temperature Superconductivity
Less than two years after shocking the science world with the discovery of a material capable of room-temperature superconductivity, a team of UNLV physicists has upped the ante once again by reproducing the feat at the lowest pressure ever recorded. The new findings were published this month as an advance article in the journal Chemical Communications.
The Strength of the Strong Force
Researchers have experimentally extracted the strength of the strong force, a quantity that firmly supports theories explaining how most of the mass or ordinary matter in the universe is generated. This quantity, known as the coupling of the strong force, describes how strongly two bodies interact or "couple" under this force. With Jefferson Lab data, the physicists were able to determine the strong force coupling at the largest distances yet.
Catching a Glimpse of the Reactive Intermediates in Water in a Trillionth of a Second
The proton-transfer and ionization process in water leads to the formation of a hydroxyl-hydronium complex, a type of hydroxyl radical. The formation process causes ultrafast structural changes and the redistribution of energy among neighboring water molecules. Thanks to recent developments in liquid phase ultrafast electron diffraction techniques, scientists can capture these processes in real time.
