Macroscopic three-dimensional (3D) graphene foams (GFs) were fabricated efficiently by immediately sintering low-temperature exfoliated graphene powder under inert atmosphere at the temperature over 500 C. The one-pot sintering process not only integrated two-dimensional (2D) graphene sheets into 3D GF, but also accelerated the structural integrity of graphene by inducing its deoxygenation

Highly Efficient Knockout of a Squid Pigmentation Gene:

Crawford et al. report the first gene knockout in a cephalopod. Using CRISPR-Cas9 in squid embryos, they target a gene encoding tryptophan 2,3 dioxygenase, an enzyme involved in ommochrome pigment production. Knockouts are highly efficient in G0 animals, resulting in a near complete lack of pigmentation and over 90% disruption of the tdo locus.
