Scientists long pondered Earth's weight, an impossible task with conventional scales. In 1798, Henry Cavendish, using a modest torsion balance with lead balls, ingeniously measured the faint gravitational pull between them. This groundbreaking experiment revealed Earth's density, finally allowing its mass to be calculated, a feat still admired for its precision and ingenuity.
Yass Queen: How the bumble stays alive underwater
Bumblebee queens possess a remarkable ability to survive underwater for days, a feat achieved through a combination of physiological strategies. When their burrows flood, these queens enter an ultra-low-power mode, drastically reducing their metabolic rate and relying on a physical gill and anaerobic metabolism to conserve energy and endure submersion until conditions improve.
