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 ...

A new approach to solving the mystery of dark energy (Update)

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.

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 ...

Ripples in fabric of universe may reveal start of time

Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos ...

Active matter theory explains fire-ant group behavior

Ants are social insects and the Solenopsis invicta species—known as the fire ant—is no exception. The social interactions of this invasive insect, which comes from South America, are framed within the context of the theory ...

Data reveal a surprising preference in particle spin alignment

Given the choice of three different "spin" orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher at the U.S. Department of Energy's (DOE) Brookhaven National ...

Nobel-winning Swiss physicist Muller dies at 95

Swiss physicist Karl Alex Muller, who won the Nobel Physics Prize in 1987 along with his German colleague Georg Bednorz for their discovery of the first high-temperature superconductor, has died.

How to shelter from a nuclear explosion

There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance. In between, there is another danger: the blast wave ...
