Tiny anti-cancer weapons: nano-sized particles cause tumor cells to self-destruct
DR5-scFv induces apoptosis of DR5+ tumor cells. Credit: Science Advances (2025). DOI: 10.1126/sciadv.adp9009 A preclinical study by researchers at the Perelman School of Medicine at the University of Pennsylvania has added a new twist to a decades-old anti-cancer strategy, showing powerful effects against multiple cancer types. This experimental approach, which uses tiny capsules called small extracellular vesicles (sEVs), has the…

Tiny particles, huge potential: Scientists discover new type of quasiparticle present in all magnetic materials
Quasiparticle-mediated dynamics in AFM and FM honeycomb lattices of contracted nanoscale elements. Credit: Physical Review Research (2024). DOI: 10.1103/PhysRevResearch.6.043144 Researchers recently made a breakthrough discovery at the nanoscale. It is a new type of quasiparticle that is present in all magnetic materials, regardless of strength or temperature. These new properties challenge what researchers previously knew about magnetism and show that…

Research team succeeds in ultra-fast switching of tiny light source
Intense light pulses in the terahertz range separate the charged, emissive trions into individual electrons and neutral excitons. Credit: Giuseppe Meneghini Ultrathin materials consisting of just a few atomic layers hold promise for applications in electronics and quantum technology. An international team led by the Technical University of Dresden has made remarkable progress in experiments carried out at the Helmholtz…

New video shows tiny spacecraft ‘swarming’ Proxima Centauri
A screenshot from an animation showing the Proxima Centauri cluster approaching Proxima b. Credit: i4is/Interstellar Initiatives Earlier this year, NASA selected a very interesting proposal for Phase I development as part of the NASA Innovative Advanced Concepts (NIAC) program. Known as Swarming Proxima Centauri, it is a collaboration between Space Initiative and the Initiative for Interstellar Studies (i4is), led by…
