Exoskeleton for paralyzed sperm

The sperm, dressed in an exoskeleton, reaches the egg with "dizzying" speed, and the microdrive even helps it to get inside, making the fertilization process as easy as possible

Mysterious Anti-cancer Nanoparticles

Nanoparticles from the shells of the virus that infects legumes in mice with melanoma and other forms of cancer stimulated the immune system, which destroyed not only the tumor itself, but also metastases. But the mechanism of this effect is still unknown.
