Primordial mini-moons may explain meteorite composition

A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within the parent bodies of the most common meteorites? The work

Tiny silica particles wiped out aggressive prostate cancer in mice

Tiny silica nanoparticles engineered to seek out prostate cancer caused tumor cells to self-destruct and supercharged the immune system in preclinical mouse studies. Combined with immunotherapy, the treatment produced complete remissions in multiple mice, raising hopes for a powe
