What really happens at femtosecond junctions?

When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are complicated, and their mathematical ...

How living systems compute solutions to problems

How do decisions get made in the natural world? One possibility is that the individuals or components in biological systems collectively compute solutions to challenges they face in their environments. Consider that fish ...

Your own virtual heart for non-invasive heart diagnostics

EPFL mathematician Alfio Quarteroni and his team are building a virtual heart model based on personalized medical images that may one day help cardiologists and cardiac surgeons non-invasively diagnose pathological heart ...

Scientists predict the existence of a new kind of spin liquid

A team of physicists at the Okinawa Institute of Science and Technology Graduate University (OIST) has predicted the existence of a new kind of spin liquid. A spin liquid is an exotic phenomenon that intrigues scientists: ...

When diffusion depends on chronology

The Internet, motorways and other transport systems, and many social and biological systems are composed of nodes connected by edges. They can therefore be represented as networks. Scientists studying diffusion over such ...

Theorists weigh in on where to hunt dark matter

(Phys.org) —Now that it looks like the hunt for the Higgs boson is over, particles of dark matter are at the top of the physics "Most Wanted" list. Dozens of experiments have been searching for them, but often come up with ...

Heliophysics nugget: Gradient sun

(Phys.org)—Heliophysics nuggets are a collection of early science results, research techniques and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth.
