Amateur Mathematician Finds Smallest Universal Cover
Posted on Thursday November 15, 2018

Through exacting geometric calculations, Philip Gibbs has found the smallest known cover for any possible shape.

How Holography Could Help Solve Quantum Gravity
Posted on Wednesday November 14, 2018

In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.

An Italian Cosmologist Who Wanders in Dante’s Dark Wood
Posted on Tuesday November 13, 2018

A scientist and programmer with a literary bent, Valeria Pettorino thinks multiple angles and diverse points of view are needed to unriddle the nature of dark matter and dark energy.

Stem Cells Remember Tissues’ Past Injuries
Posted on Monday November 12, 2018

Stem cells seem to retain memories of old injuries to improve future healing. When that system goes wrong, chronic inflammation can result.

Solution: ‘How Equality and Inequality Shape Birds and Bees’
Posted on Friday November 09, 2018

Puzzle solvers explored how evolution may have used negative and positive control mechanisms to shape the conflicting parental functions of reproduction and child rearing.

Quantum science turns social
Posted on Wednesday November 14, 2018

Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems.

When electric fields make spins swirl
Posted on Wednesday November 14, 2018

Scientists have reported the discovery of small and ferroelectrically tunable skyrmions. Published in Nature Materials, this work introduces new compelling advantages that bring skyrmion research a step closer to application.

Optimization of alloy materials: Diffusion processes in nano particles decoded
Posted on Tuesday November 13, 2018

A research team discovers atomic-level processes which can provide new approaches to improving material properties.

Scientists shed light on semiconductor degradation mechanism
Posted on Tuesday November 13, 2018

SiC-based electrical devices degrading will be improved by controlling the semiconductor material deformation with atomic level.

New finding of particle physics may help to explain the absence of antimatter
Posted on Tuesday November 13, 2018

With the help of computer simulations, particle physics researchers may be able to explain why there is more matter than antimatter in the Universe. The simulations offer a new way of examining conditions after the Big Bang, and could provide answers to some fundamental questions in particle physics.
