So you can't afford a fancy mechanical keyboard but still want your cheapo one to sound like one?

This thingy works surprisingly well.

Chaotic Clouds of Jupiter

This image captures swirling cloud belts and tumultuous vortices within Jupiter’s northern hemisphere.

NASA’s Juno spacecraft took this color-enhanced image at 10:23 p.m. PDT on May 23, 2018 (1:23 a.m. EDT on May 24), as the spacecraft performed its 13th close flyby of Jupiter. At the time, Juno was about 9,600 miles (15,500 kilometers) from the planet's cloud tops, above a northern latitude of 56 degrees.

The region seen here is somewhat chaotic and turbulent, given the various swirling cloud formations. In general, the darker cloud material is deeper in Jupiter’s atmosphere, while bright cloud material is high. The bright clouds are most likely ammonia or ammonia and water, mixed with a sprinkling of unknown chemical ingredients.

A bright oval at bottom center stands out in the scene. This feature appears uniformly white in ground-based telescope observations. However, with JunoCam we can observe the fine-scale structure within this weather system, including additional structures within it. There is not significant motion apparent in the interior of this feature; like the Great Red Spot, its winds probably slows down greatly toward the center.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft’s JunoCam imager.

JunoCam's raw images are available for the public to peruse and process into image products at www.missionjuno.swri.edu/junocam

Programmable Water Droplets

The ability of a liquid to maintain contact with a solid surface is a property called wetting. It is determined by the balance between adhesive and cohesive forces resulting from intermolecular interactions. Adhesive forces cause the liquid to spread across a surface while cohesive forces cause the liquid to ball up and avoid contact. Water-repellant fabrics are an example of non-wetting materials because they minimize interactions between the surface and water droplets.

Electrowetting is a technique to modify the wetting properties of a surface using an external electric field. Dielectric arrays can be used to create microfluidic devices that allow for programatic control of droplet motion. Scientists have used these techniques to perform biological automation and are now exploring the possibility of water-based computer interfaces.

Hear my feelings. But can you feel them?
Higher Empathy People Process Music Differently in the Brain

People with higher empathy differ from others in the way their brains process music. The researchers found that compared to low empathy people, those with higher empathy process familiar music with greater involvement of the reward system of the brain, as well as in areas responsible for processing social information.

The research is in Frontiers in Behavioral Neuroscience. (full open access)

+Solamon Grundy I wonder if the charity we provide to the apologists is warranted. It just doesn't seem as though their arguments are worth giving them that kind of space. I feel more and more like we are listening to people who believe in the yeti, and instead of gasping and raising eyebrows we let them share their grainy photos of snowmen in the distance and give it serious thought.

Or am I too isolated from the debate lately to realise the depth and quality of their position?
