Predicting human group sizes with physics
Only by knowing the average number of friends each person has, scientists at Complexity Science Hub (CSH) were able to predict the group sizes of people in a computer game. For this purpose, they modeled the formation of ...

Modulating magnetism in a Weyl semi-metal using current-assisted domain wall motion
Spintronic devices are emerging technologies that exploit the intrinsic spin of electrons to store and process data. These technologies have the potential to outperform conventional electronics both in terms of speed and ...
Scientists observe 'quasiparticles' in classical systems for the first time
Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic ...

Transistors repurposed as microchip 'clock' address supply chain weakness
Microchip fab plants in the United States can cram billions of data processing transistors onto a tiny silicon chip, but a critical device, in essence a "clock," to time the operation of those transistors must be made separately—creating ...

Study demonstrates a new method to search for meV dark photons
Approximately 85% of the mass of our galaxy is comprised by dark matter, matter that does not emit, absorb or reflect light and thus cannot be directly observed. While several studies have hinted at or theorized about its ...
Excavation of massive underground caverns for Deep Underground Neutrino Experiment halfway complete
Deep below the surface in South Dakota, construction crews have been working tirelessly to carve out a network of caverns and tunnels that one day will house a huge neutrino experiment. Their efforts are paying off: With ...

Transforming chaos into manufacturable forms with 3D printing
The further out in time, the more unreliable a weather forecast. That's because small variations in initial weather conditions can completely change the entire system, making it unpredictable. Put another way, in the "butterfly ...

Researchers derive a unified topological speed limit for the evolution of physical states
Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that ...
How a 3-centimeter glass sphere could help scientists understand space weather
Solar flares and other types of space weather can wreak havoc with spaceflight and with telecommunications and other types of satellites orbiting Earth. But to date, scientists' ability to research ways to overcome that challenge ...
