Dream Engineering, the Proton Radius Puzzle, and an ALS Breakthrough

Imagine if scientists could take a small sample of your skin, turn those cells into the exact type of brain cells that are dying in ALS, and then test hundreds of potential medicines on them in a lab dish. That's essentially what this research accomplished. Scientists took skin cells from 100 people with ALS, converted them into motor neurons (the brain cells that control muscle movement), and discovered that these lab-grown neurons died in the same way as they do in actual ALS patients. When they tested over 100 drugs that had failed in human trials, 97% also failed in their lab model - proving their system works like the real disease. Most importantly, they found a combination of three drugs that kept the neurons alive longer, offering new hope for treatment.

Scientists played specific sounds to people while they were dreaming during REM sleep, which made them dream about puzzles they couldn't solve earlier. When people had more dreams about those puzzles, they were better at solving them the next day, proving that dreams can actually help with creative problem-solving.

Scientists made an incredibly precise measurement of light emitted by hydrogen atoms that tested one of physics' most fundamental theories - the Standard Model - to an accuracy of 0.7 parts per trillion. This measurement also resolved a long-standing disagreement about the size of protons by confirming the smaller value found in previous experiments with exotic atoms.
