Some animals can move efficiently beneath granular surfaces. These include the sandfish (Scincus scincus), a lizard native to the Sahara. It can burrow into the sand and then literally “swim” through the desert sand to hunt or escape predators.

The principles of movement underlying this ability have only been understood for a few years. Researchers at the University of Würzburg have now translated the sandfish’s locomotion mechanism into an initial technical solution—an innovative Mars rover that outperforms other models when moving on sand.

The team led by computer scientist Marco Schmidt, Professor for Embedded Systems and...

Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web — the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 million light-years and links two galaxies from nearly 12 billion years ago...

Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old...

A mysterious new cosmic pattern discovered by the DAMPE space telescope may finally crack the century-old mystery of cosmic rays. Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, researchers found that cosmic ray particles—from tiny protons to heavy iron nuclei—all begin fading away more sharply at the exact same point, hinting at a universal rule governing their behavior across the galaxy.

For more than 100 years, scientists have been trying to understand cosmic rays, incredibly powerful particles that travel across the universe at extreme energies...
