A 50-year-old debate has at last been settled: the highest-energy cosmic rays do not originate in our own Galaxy but in galaxies located tens or even hundreds of millions of light years away. The evidence comes from the Pierre Auger Observatory in Argentina, which has been gathering data since 2004 about these particles that constantly bombard the Earth. The CNRS is the observatory's principal French funding agency.
When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many labs. They describe their results this week in Applied Physics Letters.
according to scientists from Aalto University Finland, viruses and nanoparticles can be assembled into processable superlattice wires. The demonstration shows that electrostatic self-assembly of nanoparticles can potentially be used to form processable materials for future applications.
Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. This is a crucial step towards realizing a quantum repeater for high-dimensional entangled states.
International collaboration by scientists with the Pierre Auger Observatory confirms that most of the highest energy cosmic rays that reach the Earth come from outside the Milky Way galaxy.
HRL Laboratories, LLC, has made a breakthrough in metallurgy with the announcement that researchers at the famous facility have developed a technique for successfully 3-D printing high-strength aluminum alloys that opens the door to additive manufacturing of engineering-relevant alloys.
A team in the lab of Puru Jena, Ph.D., a distinguished professor in the Department of Physics in the College of Humanities and Sciences at Virginia Commonwealth University, has created the most stable tri-anion particle currently known to science. A tri-anion particle is a combination of atoms that contains three more electrons than protons. This discovery is novel because previously known tri-anion particles were unstable due to their numerical imbalance.
A University of California, Riverside-led team of physicists has found a simple and viable explanation for the diversity observed in galactic rotations. Hai-Bo Yu and colleagues report that diverse galactic-rotation curves, a graph of rotation speeds at different distances from the center, can be naturally explained if dark matter particles are assumed to strongly collide with one another in the inner halo, close to the galaxy's center -- a process called dark matter self-interaction.

In a new study published in EPJ B, Jingxi Luo and Bernard Piette from Durham University, UK, present a new mathematical model that explains the energy transport mechanism permitting energy generated inside a biological cell to move along transmembrane proteins towards the cell's exterior.
