How schools of 'microswimmers' can increase their cargo capacity

A new study published in Physical Review Letters describes a way to increase the cargo capacity of microscopic, self-propelled droplets known as "microswimmers." Researchers from the University of Pennsylvania and the Max ...

Why animals recognise numbers but only humans can do math

Counting feels utterly effortless to adults, who are unlikely to even remember when or how they picked up this useful, apparently automatic skill. Yet when you think about it, counting is a remarkable invention. It helped ...

Exploring quantum systems that don't find equilibrium

Some physical systems, especially in the quantum world, do not reach a stable equilibrium even after a long time. An ETH researcher has now found an elegant explanation for this phenomenon.

Quantum simulation: Measurement of entanglement made easier

University of Innsbruck researchers have developed a method to make previously hardly accessible properties in quantum systems measurable. The new method for determining the quantum state in quantum simulators reduces the ...

Numbers limit how accurately digital computers model chaos

The study, published today in Advanced Theory and Simulations, shows that digital computers cannot reliably reproduce the behaviour of 'chaotic systems' which are widespread. This fundamental limitation could have implications ...

Equifax to pay up to $700M in data breach settlement

Equifax has agreed to pay $700 million, potentially more, to settle with the federal authorities and states over its 2017 data breach that exposed the Social Security numbers and other private information of nearly 150 million ...
