The International Space Station is an exciting place for experiments. This one in particular was making waves in space. Called Fluidics, the experiment studies fluid dynamics in microgravity and recently performed another successful round of science on board the Space Station.

Looks like Venus has dozens of active volcanoes
“This study significantly changes the view of Venus from a mostly inactive planet to one whose interior is still churning and can feed many active volcanoes,” one scientist said. Source: https://earthsky.org/space/venus-3d-model-evidence-active-volcanoes…
Subsurface vortexes may have created Saturn’s mysterious hexagon
Two researchers investigated the dynamics of Saturn’s churning atmosphere to figure out what sorts of planetary fluid dynamics are creating its mystifying hexagon. Source: https://www.livescience.com/saturn-hexagon-subsurface-vortexes.html
Global warming is influencing where tropical cyclones rage
While the global average number of tropical cyclones each year hasn’t budged from 86 over the last 4 decades, climate change has been influencing the locations of these deadly storms. Source: https://earthsky.org/earth/study-climate-change-tropical-cyclones-hurricanes-location…
Superfuids may merge via corkscrew mechanism
Scientists at the Florida State University-headquartered National High Magnetic Field Laboratory have made a discovery in fluid dynamics that is truly worth uncorking a bottle of fine wine. …
Mystery Sounds From Storms Could Help Predict Tornadoes
Mysterious rumbles that herald tornadoes could one day be used to predict when and where they will strike, according to researchers. From a report: Storms emit sounds before tornadoes form, but the signals at less than 20Hz are below the limit for human hearing. What causes these rumbles has also been a conundrum. Now researchers said they have narrowed down the…
Analysis of Galileo’s Jupiter entry probe reveals gaps in heat shield modeling
The entry probe of the Galileo mission to Jupiter entered the planet’s atmosphere in 1995 in fiery fashion. As the probe descended from Mach 50 to Mach 1 and generated enough heat to cause plasma reactions on its surface, it relayed data about the burning of its heat shield that differed from the effects predicted in fluid dynamics models. New work…
A Restart For the Aptera Electric Car?
necro81 writes: The Aptera 2e was a head-turning 3-wheeled electric vehicle when it debuted a decade ago. With a body more like an aircraft than a car, it was designed for maximum efficiency. Unfortunately, the company went bankrupt and liquidated before it hit production. Now IEEE Spectrum reports the founders are having another crack at it, taking advantage of a decade…
Will planetary low tide force regular sunspot sync-ups?
No, it’s not pseudoscience. Does a regular alignment of planets make a strong-enough tug to regulate the sun’s 11- and 22-year cycles? Read more in this story via Eos – a source for news and perspectives about Earth and space science – from the American Geophysical Union.

How to make the perfect crêpe according to fluid dynamics
It’s hard to make crêpe batter spread evenly before it cooks, but an analysis of the physics involved says a tilt and swirl of the pan gives the perfect pancake Source: https://www.newscientist.com/article/2206621-how-to-make-the-perfect-crepe-according-to-fluid-dynamics/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
