How Network Math Can Help You Make Friends
Posted on Monday August 20, 2018

Studying the structure of existing friendships in your community can help you forge the best connections when forming a new circle of friends.

‘Functional Fingerprint’ May Identify Brains Over a Lifetime
Posted on Thursday August 16, 2018

A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.

Evolutionary Math and Just-So Stories
Posted on Wednesday August 15, 2018

Evolutionary stories like the grandmother hypothesis are easy to construct from mathematical models, but how well do they reflect reality?

How Insulin Helped Create Ant Societies
Posted on Tuesday August 14, 2018

Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.

Universal Method to Sort Complex Information Found
Posted on Monday August 13, 2018

The nearest neighbor problem asks where a new point fits into an existing data set. A few researchers set out to prove that there was no universal way to solve it. Instead, they found such a way.

Light from ancient quasars helps confirm quantum entanglement
Posted on Monday August 20, 2018

New research boosts the case for quantum entanglement. Scientists have used distant quasars, one of which emitted its light 7.8 billion years ago and the other 12.2 billion years ago, to determine the measurements to be made on pairs of entangled photons. They found correlations among more than 30,000 pairs of photons -- far exceeding the limit for a classically based mechanism.

Link between magnetic field strength and temperature
Posted on Monday August 20, 2018

Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process corresponds to the temperature of the material. Based on this finding, scientists can determine a sample's temperature to a resolution of one cubic micron by measuring the field strength at which this effect occurs. Temperature sensing is integral in most industrial, electronic and chemical processes, so greater spatial resolution could benefit commercial and scientific pursuits.

A valley so low: Electrons congregate in ways that could be useful to 'valleytronics'
Posted on Saturday August 18, 2018

Researchers have made a finding that could help usher in new area of technology called 'valleytronics.' The study found that electrons in bismuth crystals prefer to collect in one valley rather than being distributed equally across valleys, setting up a type of electricity known as ferroelectricity.

Quantum material is promising 'ion conductor' for research, new technologies
Posted on Thursday August 16, 2018

Researchers have shown how to shuttle lithium ions back and forth into the crystal structure of a quantum material, representing a new avenue for research and potential applications in batteries, 'smart windows' and brain-inspired computers containing artificial synapses.
