Foxes hunt rodents in the snow by listening for their movements and leaping high
to pounce on their prey
. Interestingly, they hunt most successfully when they jump in a north-easterly direction - 73% of the time. Jumping in the opposite direction has a 60% success rate. Pouncing in other directions was successful only 18% of the time. This was consistent regardless of time of day, season of year and weather conditions. [more inside]

Hacking the Senses
: The brain is far more plastic than we commonly realize. Presenting new 'senses' via the old inputs works extremely well, to the point that long-term volunteers are a little lost without their new abilities to feel magnetic north or absolute orientation. Tasting direction; feeling pictures. Fascinating stuff. In a loosely related article, genetically modified mice
are able to see the full color range visible to humans, even though the last natural mouse able to see this way died out a hundred million years ago. Add the new sensors, and the brain reconfigures. [via]

Seeing with sound.
A researcher in the Netherlands has developed a system that converts pictures from a head-mounted camera into highly complex soundscapes, which are then piped to the user via headphones. After only a week of use, a woman who has been blind from birth can tell a CD from a floppy, and discern whether the lights are on or off. Not quite up to either a bat and/or Daredevil
standards, but very cool nonetheless.

"Modern scientists have known about synesthesia
since 1880, when Francis Galton
, a cousin of Charles Darwin
, published a paper in Nature on the phenomenon. But most have brushed it aside as fakery, an artifact of drug use (LSD
can produce similar effects) or a mere curiosity. About four years ago, however, we and others began to uncover brain processes that could account for synesthesia. " This article
from Scientific American seems to be turning heads around the Psychology Department at U of M [Michigan]. It's got me going too.
I've seen real connections between color and sound before, stone sober. Could there be something to all this?

A set of 24 colour blindness tests
I picked up this link from the comments in another forum, somebody mentioned they were colour blind and provided a link to these tests. Interestingly the colour blind can also see stuff that normally sighted people can't.

Cool eyeball science
Quick summary of interesting research on the output of the eyeball. 3 really cool things: 1, we know much more about the output of the eyeball now than a few years ago; 2, they've got a neural network doing visual processing like the eye; 3, most of what you see your brain makes up!
