NASA Is Sending a Life-Hunting Drone to Saturn’s Huge Moon Titan

Posted by in categories: drones, space

NASA is going to Titan.

The space agency announced today (June 27) that the next mission in its New Frontiers line of medium-cost missions will be Dragonfly, a rotorcraft designed to ply the skies of the huge, hazy and potentially life-hosting Saturn moon.

If all goes according to plan, Dragonfly will launch in 2026 and land on Titan eight years later, NASA officials said. The probe will then spend at least 2.5 years cruising around the 3,200-mile-wide (5,150 kilometers) moon, making two dozen flights that cover a total of about 110 miles (180 km).

Experiment reverses the direction of heat flow

Posted by in categories: energy, quantum physics

Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up. This is a natural phenomenon we experience all the time. It is explained by the second law of thermodynamics, which states that the total entropy of an isolated system always tends to increase over time until it reaches a maximum. Entropy is a quantitative measure of the disorder in a system. Isolated systems evolve spontaneously toward increasingly disordered states and lack of differentiation.

An experiment conducted by researchers at the Brazilian Center for Research in Physics (CBPF) and the Federal University of the ABC (UFABC), as well as collaborators at other institutions in Brazil and elsewhere, has shown that quantum correlations affect the way entropy is distributed among parts in thermal contact, reversing the direction of the so-called “thermodynamic arrow of time.”

In other words, heat can flow spontaneously from a cold object to a hot object without the need to invest energy in the process, as is required by a domestic fridge. An article describing the experiment with theoretical considerations has just been published in Nature Communications.

Lightning bolt underwater

Posted by in categories: climatology, engineering, physics

Electrochemical cells help recycle CO2. However, the catalytic surfaces get worn down in the process. Researchers at the Collaborative Research Centre 1316 “Transient atmospheric plasmas: from plasmas to liquids to solids” at Ruhr-Universität Bochum (RUB) are exploring how they might be regenerated at the push of a button using extreme plasmas in water. In a first, they deployed optical spectroscopy and modelling to analyse such underwater plasmas in detail, which exist only for a few nanoseconds, and to theoretically describe the conditions during plasma ignition. They published their report in the journal Plasma Sources Science and Technology on 4 June 2019.

Plasmas are ionised gases: they are formed when a gas is energised that then contains free electrons. In nature, plasmas occur inside stars or take the shape of polar lights on Earth. In engineering, plasmas are utilised for example to generate light in fluorescent lamps, or to manufacture new materials in the field of microelectronics. “Typically, plasmas are generated in the gas phase, for example in the air or in noble gases,” explains Katharina Grosse from the Institute for Experimental Physics II at RUB.

Microscopic glass blowing used to make tiny optical lenses

Posted by in category: biotech/medical

Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature cone-shaped lenses known as axicons.

Axicons are used to shape in a way that is beneficial for optical drilling, imaging and creating for manipulating particles or cells. These lenses have been known for more than 60 years, but their fabrication, especially when small, is not easy.

“Our technique has the potential of producing robust miniature axicons in glass at a low cost, which could be used in miniaturized imaging systems for biomedical imaging applications, such as , or OCT,” said research team member Nicolas Passilly from FEMTO-ST Institute in France.
