Participants who exercised before sleeping 4.5 hours performed as well on a memory test as those who slept 8.5 hours without exercising. The benefit was linked to increased deep sleep, which aids in memory consolidation.

   Asteroid Bennu's Fragility Revealed by Particle Size and Shape

   A new study published in Nature Communications shows that the tensile strength of granular asteroids like Bennu can be predicted by the size and shape of their constituent particles. Larger and more spherical particles result in weaker asteroids, while irregular, flattened chips and fine dust provide more cohesion. Bennu's surface is exceptionally weak, with a strength below 1 pascal, due to the dominance of millimeter-to-centimeter-sized fragments and the absence of fine dust.

   How Fats Leave the Body During Weight Loss

   When we lose weight, stored fats are broken down and primarily excreted from the body through the lungs as carbon dioxide during exhalation. This process is the main way fats leave the body, contrary to common misconceptions that they are converted into energy or heat or exit through sweating.
