Using dunes to interpret wind on Mars
Dunes develop when wind-blown sand organizes into patterns, most often in deserts and arid or semi-arid parts of the world. Every continent on Earth has dune fields, but dunes and dune-like sand patterns are also found across the solar system: On Mar.....»»
Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
By studying data from NASA's Parker Solar Probe and the ESA Solar Orbiter, an international team of astrophysicists has found that Alfvén waves drive the acceleration and heating of the solar wind......»»
Image: Saharan dust in the wind

South Africa"s coal workers face uncertainty—study shows they"re being left out of the green transition
South Africa is on the path to decarbonization—doing away with burning coal and other fossil fuels and moving towards renewable, clean energy, such as solar and wind power. However, the coal industry employs 91,000 people. If these workers lost the.....»»
Teens recognize risk behavior in movies and series, but are not always critical
When teens see risk behavior such as drinking, smoking or drug use in movies or series, they sometimes find it difficult to define whether it's realistic or not. They recognize stereotypes but cannot always interpret it critically. This is according.....»»

Rocks collected on Mars hold key to water and perhaps life on the planet: Researchers urge bringing them back to Earth
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the red planet and even contain evidence for past life on Mars......»»
Why cricket’s latest bowling technique is so effective against batters
Wind tunnel experiments show how the ball's transverse spin impacts pressure fields. Enlarge / Some cricket bowlers favor keeping the arm horizontal during delivery, the better to trick the batsmen. (credit: Rae Allen/CC BY 2.0).....»»
Cricket physics: Wind tunnel experiments reveal why bowling with a near horizontal arm makes for tough batting
Key to winning a cricket match is tricking the other team's batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizo.....»»
Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, cany.....»»
Mars has ‘oceans’ worth’ of water – but it’s deep underground
Researchers have identified what they believe could be oceans' worth of water on Mars. There's just one snag: it's deep underground......»»
Scientists find oceans of water on Mars. It"s just too deep to tap.
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water—enough to fill oceans on the planet's surface......»»
