Deadly life…
A once-maligned genetic parasite may actually be essential for survival. Mouse embryos need that genetic freeloader — a type of jumping gene causing mutations, or transposon, called LINE-1 — to continue developing past the two-cell stage, researchers reported in Cell. Transposons certainly can hop into and break genes, and cells deploy numerous tools to prevent…

Killing humans. By analyzing rocks. [Brake that rock!]
University of California, Berkeley neuroscientists have tracked the progress of a thought through the brain, showing clearly how the prefrontal cortex at the front of the brain coordinates activity to help us act in response to a perception. Recording the electrical activity of neurons directly from the surface of the brain, the scientists found that…

Editing DNA vs. Evolution. Change vs. One. A battle lost before it even starts.
Octopus, squid, and cuttlefish are famous for engaging in complex behavior, from unlocking an aquarium tank and escaping to instantaneous skin camouflage to hide from predators. A new study suggests their evolutionary path to neural sophistication includes a novel mechanism: Prolific RNA editing at the expense of evolution in their genomic DNA.

DNA. epigenetics, gods…
Researchers at the BBSRC-funded Babraham Institute, in collaboration with the Wellcome Trust Sanger Institute Single Cell Genomics Centre, have developed a powerful new single-cell technique to help investigate how the environment affects our development and the traits we inherit from our parents. The technique can be used to map all of the ‘epigenetic marks’ on…
