Four-legged robot learns dog-like movements to leap through tight spaces
Cats, dogs, wolves and other agile four-legged animals can easily jump and squeeze through tight spaces while moving at high speed. Reproducing similar agile motions and skills in quadrupedal robots has so far proved challenging.
Peptides can form well-defined structures in harsh, Venus-like conditions
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mounting evidence suggests that the ingredients ...
