Water bears, known to scientists as tardigrades, are famously adorable microscopic creatures who can survive anything: freezing, total dehydration, radiation bombardment, and even the vacuum of deep space. Now scientists have sequenced a tardigrade genome, and are very surprised by the results.
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.
