NASA Updates Preview Briefing for International Space Station Spacewalks, Live Coverage

Experts from NASA will preview two upcoming spacewalks outside the International Space Station to continue upgrades to the orbiting laboratory’s power system in a briefing at 2 p.m. EDT Thursday, Sept. 27, at the agency’s Johnson Space Center in Houston.

Quantum anomaly: Breaking a classical symmetry with ultracold atoms

A new study of ultracold atomic gases finds a quantum anomaly: strongly interacting particles breaking classical symmetry in a 2-D Fermi gas.

Lighting it up: A new non-toxic, cheap, and stable blue photoluminescent material

Scientists have designed a novel photoluminescent material that is cheap to fabricate, does not use toxic starting materials, and is very stable, enhancing our understanding of the quantic nature of photoluminescence.

How long does a quantum jump take?

Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely -- for example the famous 'photoelectric effect', first described by Albert Einstein.

New nanoparticle superstructures made from pyramid-shaped building blocks

In research that may help bridge the divide between the nano and the macro, chemists have used pyramid-shaped nanoparticles to create what might be the most complex macroscale superstructure ever assembled.

Engineers develop first method for controlling nanomotors

Engineers have developed the world's first method for controlling the motion of nanomotors with simple visible light as the stimulus.

Two quantum dots are better than one: Using one dot to sense changes in another

Researchers developed the first device that can detect single-electron events in a self-assembled quantum dot in real time. The device detects the single-electron tunneling events of one quantum dot as changes in the current produced by a second quantum dot in close proximity. This device allows single-electron events in quantum dots to be investigated, which is beneficial for the development of photonic devices and quantum computing.

The hunt for leptoquarks is on

Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make up protons and neutrons). Under the Standard Model, these two families are totally distinct, with different electric charges and quantum numbers, but have the same number of generations (see image below).

Airbnb distribution may depend on who lives there, not just distance to city center

Distribution of Airbnbs may follow the same pattern across different cities, and several factors, including the number of residents who work in the creative industries, may determine their location, according to an article published in EPJ Data Science.

First particle tracks seen in prototype for international neutrino experiment

The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE).
