Phys.org / Helical nanoparticles trigger cancer alarms and deliver gene therapy

Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while ...

Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons

Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...

Phys.org / Extragalactic positron-annihilation hotspots might mean Milky Way produces far more positrons than thought

Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
