It’s a Mess: Attempt to Connect the Messy Dots of Messy, Hard-to-Define Phenomena

What happens when you try to use new technological tools to measure and map things that are tough to define — so tough to define that people go half-crazy if they try to agree on the details of any of the definitions? The results can be messy, this paper suggests. Very messy: “Fledgling pathoconnectomics of […]

A metaphor for fMRI studies of thought?

A new study contains a poetical phrase that maybe, just maybe, is a metaphor for the severe difficulty and beauty of a great scientific quest: learning how the heck the brain manages to think. Many brain scientists use a complex technology called  “fMRI” (functional Magnetic Resonance Imaging) to make rough pictures of activity (many sorts of […]

Extraocular Phototransduction: more than meets the eye? (part 2)

We recently drew attention to the 1998 discovery at Cornell regarding the possibility of tweaking one’s cicadian rhythms by shining a bright light at the back of one’s knees. But continuing research into extraocular (outside the eye) light stimuli has turned to the possibility of a more direct route. Why not shine a light directly […]

Following in the wingbeats of the Star Wars locusts…

Newly reported research with dragonflies follows, at least in spirit, in the wingbeats of the Ig Nobel Prize-winning locust/Star Wars research. Greg Miller reports on the new work, in Wired: Scientists Put Backpacks on Dragonflies to Track Their Brains in Flight The brain of a dragonfly has to do some serious calculations — and fast […]
