A recent study reports that Cesium and Silver radionuclides originated from Fukushima fallout can be found in zooplankton and some fishes in the Pacific Ocean, but states that the radiation risks are below concern for animals and humans.

Evolving and replication capable artificial molecules, XNAs (xeno-nucleic acids), which resemble DNA structure, have been reported recently. These molecules can be replicated by enzymes, reverse-transcribed to DNA and show Darwinian evolution when tested with aptamer selection experiments.

Remote controlled genes
A recent study reports the engineering of temperature-sensitive, nanoparticle-coated ion channels that can be controlled by distant microwave sources, to subsequently regulate the expression of a recombinant insulin gene controlled by a calcium-responsive promoter.
