Friction without contact discovered as magnetic forces break a 300-year-old law

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that dramatically increase resistance at certain distances. This creates a surprising peak in friction instead of a steady rise, breaking a long-standing physics law.

Single psilocybin trip delivers two years of depression relief for cancer patients

Psilocybin, the active ingredient in magic mushrooms, might just revolutionize how depression and anxiety are treated in cancer patients. In a groundbreaking trial, a single dose combined with therapy significantly reduced emotional suffering, and these effects often lasted over two years. As follow-up studies expand the research to multiple doses and larger samples, scientists are eyeing a possible new standard of care that merges psychedelics with psychological support. from Latest Science News -- ScienceDaily https://ift.tt/P1Aoby3
