Her Key to Modeling Brains: Ignore the Right Details
Posted on Tuesday June 19, 2018

Being able to think like a physicist helps Carina Curto, a mathematician-turned-neuroscientist, pull insights about the human brain out of theoretical models.

Four Is Not Enough

How many colors do you need to color an infinite plane so that no points 1 unit apart are the same color?

Brains May Teeter Near Their Tipping Point
Posted on Thursday June 14, 2018

In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.

Too Small for Big Muscles, Tiny Animals Use Springs
Posted on Wednesday June 13, 2018

Elastic springs help tiny animals stay fast and strong. New work is finding what size critters must be to benefit from the springs.

The Universe Is Not a Simulation, but We Can Now Simulate It
Posted on Tuesday June 12, 2018

Computer simulations have become so accurate that cosmologists can now use them to study dark matter, supermassive black holes and other mysteries of the real evolving cosmos.

New material for splitting water
Posted on Tuesday June 19, 2018

Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water.

The first experimental discovery of the propagation of plasma turbulence
Posted on Tuesday June 19, 2018

Scientists applied the 'heat pulse modulation method' in the magnetic island produced intentionally in the tokamak 'Doublet III-D.' Temperature gradient inherent in the magnetically confined plasma causes turbulence while there is no turbulence in the magnetic island because of the absence of the gradient. That the turbulence propagates has now been demonstrated for the first time by investigating turbulence in the magnetic island.

Sodium- and potassium-based batteries hold promise for cheap energy storage
Posted on Tuesday June 19, 2018

Researchers have found new evidence suggesting that batteries based on sodium and potassium hold promise as a potential alternative to lithium-based batteries.

Mysterious event may be caused by a tau neutrino
Posted on Tuesday June 19, 2018

Theoretical physicists calculate the origin of a high-energy particle track captured by the IceCube Neutrino Observatory.

When photons spice up the energy levels of quantum particles
Posted on Tuesday June 19, 2018

For the first time, a team of mathematical physicists, call upon supersymmetry to explain the behavior of particles that have received a photon and are subjected to particular potential energies known as shape-invariant potentials.
