Aerodynamics are an important factor in gravel racing and riding. Gravel racing speeds are high—the fastest riders in the 200-mile Unbound average 20 mph (32 km/h) across the Flint Hills of Kansas. And many gravel races can be extremely windy. Optimizing the aerodynamics of a…
Wonderful news! We just received full funding for the Galileo Project expedition to scoop the fragments of the first interstellar meteor…
Sandboxx News makes the complex approachable. Bridging the gap between academic expertise and practical boots-on-the-ground experience, we remove the mystery from conflict and highlight the importance of military service and deterrence-reinforcing technology.
You may be familiar with the term “hockey stick curve,” used describe a trend that has been flat/stable for a very long time, but shoots up at the end of the series in dramatic fashion, resembling the shape of a hockey stick. Hockey can be a violent sport, and it’s easy to get hurt by even one well-aimed swing…
I've been reading a lot of predictions from people who are looking to understand what problems humanity will face 10-50 years out (and sometimes longer) in order to work in areas that will be instrumental for the future and wondering how accurate these predictions of the future are. The timeframe of predictions that…
All energy production takes up land, but which sources use the most land, and which use it most efficiently?
Tree-planting has been widely seen as an effective way of binding carbon as carbon dioxide levels rise in the atmosphere. But now researchers from the University of Gothenburg and elsewhere are warning that forests on nutrient-poor land won’t be an additional carbon sink in the long term. As forests age, their uptake…
University of Liège researchers discover a new planetary system around a particularly small and cool star.
Posted by Richard C. Gerkin, Google Research, and Alexander B. Wiltschko, Google Did you ever try to measure a smell? …Until you can measure their ...
And they hint at a future with vastly better products
People who say “science is political” usually aren’t just stating facts - they’re trying to push something on you. Don’t let them
While reading up on architecture in Japan recently, I came across a technology that I hadn’t heard of before: the Ene-Farm. It’s a domestic energy system that is being used in Japan and…
The FAA delivered September 1 the long-sought approval of an unleaded fuel now cleared to power every spark-ignition engine on any airframe in the general aviation fleet.
Way back in the covid-filled summer of 2020, I wrote a survey article about the ridiculously-rapidly-growing Busy Beaver function. My survey then expanded to nearly twice its original length, with …
With the help of instruments designed partly in Canada, a team of Université de Montréal astronomers have discovered an exoplanet that could be completely covered in water.
Why do the black keys on the piano each have two different names? If the posts on r/musictheory are any indication, this is a persistent point of confusion, especially when music theory teachers ge…

In a paper published in the Proceedings of the National Academy of Sciences, a team led by Virginia Tech researchers presents a new method for recycling the material that also offers economic viability.
I studied physics in university, and at one point asked a professor if I should learn German, because it seemed all the key texts of early ...
Students of military history know that acoustic refraction and unusual audibility have often played significant roles in the outcome of battles. Before electrical and wireless communications became common on the tactical level, the sound of battle was often the quickest and most efficient method by which a commander…
How to Identify and Misidentify a Brown Recluse Spider by Rick Vetter Staff Research Associate, UC Riverside Dept. of Entomology
Per- and polyfluoroalkyl substances (PFAS) are man-made hazardous chemicals that are spread globally in the atmosphere and as a result they can be found in the rainwater and snow in even the most remote locations on Earth. During the last 20 years, guideline values for PFAS in drinking water, surface waters and soils…
The strange interactions of Selfhood and Multiplicity
MIT engineers have developed a method to increase wind farms’ energy output. Whereas individual turbines are typically controlled separately, the new approach models the wind flow of the entire collection of turbines and optimizes the control of individual units.
Why does anything exist? Why is there something rather than nothing? Would it not have been easier for there to be nothing at all?
