Simultaneous detection of multiple spin states in a single quantum dot

Researchers have achieved single-shot readout of three two-electron spin states of a single quantum dot. This is the first example of simultaneous detection of multiple spin states in a single quantum dot. The team measured the change in current of a quantum point contact charge sensor near a quantum dot, which depended on both spin state and spin-orbital interactions. Their findings represent a step forward on the path to realizing quantum computing.

NASA’s Kepler provides another peek at ultra-cool neighbor

On Feb. 22, astronomers announced that the ultra-cool dwarf star, TRAPPIST-1, hosts a total of seven Earth-size planets that are likely rocky, a discovery made by NASA’s Spitzer Space Telescope in combination with ground-based telescopes. NASA’s planet-hunting Kepler space telescope also has been observing this star since December 2016. Today these additional data about TRAPPIST-1 from Kepler are available to the scientific community. …

NASA Mars Orbiter tracks back-to-back regional storms

A regional dust storm currently swelling on Mars follows unusually closely on one that blossomed less than two weeks earlier and is now dissipating, as seen in daily global weather monitoring by NASA’s Mars Reconnaissance Orbiter. …

Keeping liquids off the wall

On Earth, liquid flows downhill thanks to gravity. Creating an effective liquid fuel tank involves little more than putting a hole at the bottom of a container. That won’t work in space, though. In microgravity, with no gravity to force liquids to the bottom of a container, they cling to its surfaces instead. The Slosh Coating investigation tests using a liquid-repellant coating inside a container to control the movement of liquids in microgravity. …
