Foraging footballers suggest how we come together to act as one

Matter and energy from Science Daily Feed - Mon, 03/10/2025 - 10:07pm
Originally described in the context of particles drifting through liquid, Levy walk has been found to accurately describe a very wide range of phenomena, from cold atom dynamics to swarming bacteria. And now, a new study has found Levy walk in the movements of competing groups of organisms: football teams.

Watch Blue Ghost Test its Vacuum and Drill Experiments on the Moon

Universe Today Feed - Mon, 03/10/2025 - 8:20pm

Firefly Aerospace's Blue Ghost Mission has successfully touched down on the lunar surface and is now undertaking various experiments. Two of these experiments have been captured on video; the first is the LISTER drill, capable of penetrating the lunar regolith to depths of up to 3 meters. It will provide scientists with data to measure the Moon's cooling rate. Additionally, footage has been obtained of the PlanetVac experiment, which is evaluating regolith sample collection methods under the Moon's vacuum conditions.

Building bridges in physics

Matter and energy from Science Daily Feed - Mon, 03/10/2025 - 7:46pm
Researchers show that Cartan's First Structure Equation, which relates to edge and screw dislocations in crystal lattices, can be recast in the same form as a basic mathematical formula that governs the behavior of electric currents and magnetic fields. This work can help make new concepts more understandable by employing more familiar frameworks.

Clothes dryers and the bottom line: Switching to air drying can save hundreds

Matter and energy from Science Daily Feed - Mon, 03/10/2025 - 5:17pm
By replacing clothes dyers with line drying, households in the U.S. could save upwards of $2,100 and avoid 3 tons of carbon dioxide emissions over the lifetime of a dryer. The exact impacts, however, depend on what kind of dryer you have and where you live, new research shows.

Researchers successfully prove the solution to Dudeney's 120-year-old dissection puzzle

Computers and Math from Science Daily Feed - Mon, 03/10/2025 - 10:45am
Over 120 years ago, Henry Ernest Dudeney posed the famous dissection problem of transforming a triangle into a square by cutting it into as few pieces as possible. In a new study, researchers have finally proved that the original solution, which involves only four pieces, is optimal by using a new proof technique. This technique shows for the first time that it is possible to prove the optimality of the solution to a dissection problem.

Receiving low-glucose alerts improves diabetic drivers' safety on the road

Matter and energy from Science Daily Feed - Mon, 03/10/2025 - 10:43am
A Japanese study has found that the use of continuous glucose monitoring (CGM) devices, equipped with sensors that alert diabetics when their blood sugar levels drop, can potentially make diabetic drivers safer on the road. Those who used the devices had lower incidences of low blood sugar and reported increased confidence in driving.

Are volcanoes behind the oxygen we breathe?

Matter and energy from Science Daily Feed - Mon, 03/10/2025 - 10:42am
It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers provide a mechanism to explain precursor oxygenation events, or 'whiffs,' which may have opened the door for this to occur. Their findings suggest volcanic activity altered conditions enough to accelerate oxygenation, and the whiffs are an indication of this taking place.
