Scientists reveal why walking gets so much harder with age
Walking efficiency decreases with age as the body prioritizes stability by stiffening the ankle more during each step, reducing forward motion while requiring harder muscle work. This ankle stiffening produces shorter strides and slower walking speeds, with exercises targeting balance and lower-leg strength potentially helping preserve mobility.

Radio telescopes map molecules in interstellar space to trace how stellar elements evolve into complex chemistry. These observations reveal where and how stars form by detecting molecular signatures in space.
Japan aims for the moons of Mars
Japan is preparing a mission to retrieve samples from Mars's moons to study the origins of the solar system and life on Earth. China is simultaneously pursuing a competing mission with the goal of returning samples first.
Gene-edited beagles produce no detectable major dog allergen, early tests find
Gene-edited beagles produced no detectable levels of Can f 1, the major dog allergen protein found in saliva. The finding addresses allergies affecting approximately 15% of the global population who currently rely on avoidance or immunotherapy treatments.
