T-shirt body armor

Researchers drastically increased the toughness of a T-shirt by combining the carbon in the shirt’s cotton with boron – the 3rd hardest material on earth. The result is a lightweight shirt reinforced with boron carbide, the same material used to protect tanks.

dipping in a boron solution results in a fabric that’s lightweight but tougher and stiffer than the original T-shirt, yet flexible enough that it can be bent.

Anoxic metazoa

This is the first evidence of a metazoan life cycle that is spent entirely in permanently anoxic sediments. Our findings allow us also to conclude that these metazoans live under anoxic conditions through an obligate anaerobic metabolism that is similar to that demonstrated so far only for unicellular eukaryotes. The discovery of these life forms opens new perspectives for the study of metazoan life in habitats lacking molecular oxygen.

these are the first multicellular organisms that live without oxygen.
