Giant viruses, containing unique genes unlike those found in any other life (as well as genes not normally found in viruses, such as those for protein synthesis) are forcing new speculations about very early life on Earth.
I’ve passed on the usual stories about Phineas Gage, and how his famous incident changed him into a sociopath. It turns out that how his damage affected his personality is less certain than we thought.
Why do we yawn?

So there’s a copepod, normally transparent, whose shell has a gap between two crystalline plates of just the right size to reflect blue light while allowing other frequencies to pass. Thus it shimmers between invisible and iridescent blue.
Some new work in how memories are formed. It looks like certain mRNAs are molecularly masked and unmasked based on activity in the neuron, so that translation occurs based on which synapses are active.
Injecting good copies of a gene directly into the retina of patients with a genetically-based progressive blindness causes significant improvement in many of them.
