‘History’s most precise experiment’: How Henry Cavendish weighed the Earth with just two lead balls in a closed room 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. What if NASA’s 600-kilogram satellite crashes on Earth? Van Allen Probe A’s fiery re-entry explained Real, fake or overblown? Sorting fact from fiction in fraud allegations surrounding Newsom, California Fraud allegations are increasingly being deployed as a political weapon against Newsom, a leading Trump critic and a potential 2028 Democratic presidential contender. |
Scientists may have found a pill for sleep apnea A European clinical trial found that the drug sulthiame significantly reduced breathing interruptions in people with moderate to severe sleep apnea. Patients taking higher doses experienced up to 47% fewer pauses in breathing and improved oxygen levels during sleep. The drug helps stabilize breathing signals in the brain, reducing airway collapse. Scientists say the findings could pave the way fo… NASA inspector general assesses agency’s management of moon lander risk NASA's Office of Inspector General said that while NASA is working to "mitigate and prevent hazards" associated with lunar landers being built by SpaceX and Blue Origin, "there are currently gaps in the agency's approach, including in its testing posture and crew survival analyses," including what might happen after a catastrophic but non-fatal event. |
