If bacteria stick together, they can survive for years in space
Tiny clumps of bacteria can survive at least three years in outer space. This raises the prospect of interplanetary travel by microbial life.

Toxic germs on its skin make this newt deadly
Bacteria living on the skin of some rough-skinned newts make tetrodotoxin. This paralyzing poison is also found in pufferfish.
- Plants
Silk-based microneedles may help treat diseased plants
Engineers have invented silk microneedles to inject medicines into plants. One day farmers might use drones to dart their sick plants with meds from the air.
