A candid debate on AI in research, a warning about quantum-era data security and the Forum's first participant-driven "Un-Conference" defined a week that brought 21 laureates together with 200 young researchers from more than 50 countries

While gut bacteria clearly influence host health, determining whether they or their metabolic byproducts alone contribute to longevity remains challenging. A recent study using gnotobiotic flies colonized with genetically engineered Escherichia coli demonstrated that bacterial polyamines directly extend host lifespan. By clearly separating metabolite effects from bacterial presence, these findings highlight gut-derived polyamines as a tangible, promising target for future life-extending strategies for healthy longevity.

Researchers at the Research Center for Materials Nanoarchitectonics (MANA), one of the centers under the National Institute for Materials Science (NIMS), Japan, discovered that atomic-scale steps can guide superconducting vortices in an ultrathin superconductor. Vortices moved more than 1,000 times more easily along the steps than across them, and this guiding effect could be tuned by temperature and magnetic field.
