BASE Antimatter Experiment opens up new possibilities in the search for cold dark matter

BASE opens up new possibilities in the search for cold dark matter.

The Baryon Antibaryon Symmetry Experiment (BASE) at CERN’s Antimatter Factory has set new limits on how easily axion-like particles in a narrow mass range around 2.97 neV can turn into photons, the particles of light. BASE’s new result, published by Physical Review Letters, describes this pioneering method and opens up new experimental possibilities in the search for cold dark matter.

How chromosomes evolve to create new forms of life

Posted by in categories: biological, materials

3D printing is a universal process in the sense that pretty much any part that can be drawn up in a CAD program can be printed, at least within a certain resolution. Machining a part on a mill or lathe, while having the advantage of greater accuracy and material options, is a slightly less universal process in that many possible designs that exist in theory could never be machined. A hollow sphere can easily be printed, but a ball could never be milled as a single part into a hollow sphere—unless you happen to have a milling machine tiny enough to fit inside the ball. But what about biological parts, and whole animals? How universal, from a design perspective, is growth?

This is why mental health should be a political priority

Posted by in categories: finance, neuroscience

It’s an age-old question: does money make us happier? The answer, it seems, is yes, when it comes to the links between poverty and poor mental health. The good news is that, according to a new study, targeted financial support and low-cost therapeutic interventions can help.

Facebook’s ‘Oversight Board’ overturns four of five cases in first rulings

Posted by in category: futurism

“The board’s first rulings concerned five cases in which Facebook had removed posts for violating its policies. And in four out of the five cases reviewed, the board voted to overturn Facebook’s original decisions. The board also called on Facebook to give users greater clarity over its policies and how it intends to enforce them.”

“For all board members, you start with the supremacy of free speech,” Alan Rusbridger, a board member and former editor-in-chief of The Guardian, said.

Efficiently Converting Light Energy Into Surface Waves on Graphene

Posted by in categories: energy, nanotechnology, physics

Dotty graphene and doping: Whatever it takes for Russia’s record plasmonics to shine.

Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The paper came out in Laser & Photonics Reviews.

Manipulating light at the nanoscale is a task crucial for being able to create ultracompact devices for optical energy conversion and storage. To localize light on such a small scale, researchers convert optical radiation into so-called surface plasmon-polaritons. These SPPs are oscillations propagating along the interface between two materials with drastically different refractive indices — specifically, a metal and a dielectric or air. Depending on the materials chosen, the degree of surface wave localization varies. It is the strongest for light localized on a material only one atomic layer thick, because such 2D materials have high refractive indices.
