Researchers are developing a system that will allow humans and dolphins to speak to one another. Can I get a "woah! dude!" please? This is straight out of Star Trek. We were supposed to have to wait another 300 years at least for this kind of technology.
This is incredibly interesting stuff. Much is made about the existence or nonexistence of extraterrestrial intelligence, but we've been sharing this planet with several other intelligent species the whole time - and we haven't been able to communicate with them much at all. Gorillas and chimpanzees have learned American Sign Language and given us some clues about what it's like to be a different kind of ape, and Alex the parrot helped prove that higher cognition isn't just the purview of mammals, but what kind of culture develops underwater? What differences in the development of mind does an aquatic environment make? What's it like not to have fire or opposable thumbs? Learning from the other inhabitants of this planet can give us a much better idea of how self-awareness arises in response to wildly differing environments.

If Memory Serves
New research on marine snails suggests that science is drawing closer to the day when memories may be erased at will, like something out of The Eternal Sunshine of the Spotless Mind. There's some debate as to whether this could possibly be a good thing - after all, even our worst traumas prove formative and can mold us into wiser, happier people in the long run.
But what about those trapped in the endless nightmare of Post-Traumatic Stress Disorder? Sometimes the mechanisms in the brain for dealing with bad memories become stuck, and we lose our ability to move on.
Memory is more than just a read/write function of the brain though - it's made up of somatic feedback loops and automated responses that arise from the body, not from the mind. I wonder, if we remove the memory, would that necessarily remove the behavior? Or would it perhaps just remove the fulcrum against which we might eventually get some traction to change the out-of-control distress response?
My father died of complications related to senile dementia, and I've watched several other close relatives falter under the gradual erosion of Alzheimer's disease. From my own observations I am unconvinced that memory erasure would bring definitive relief from behavioral problems, but I'm glad to see that we're learning so much about the physical mechanisms involved.

Outside of the Box
We live in a box we can't see out of. Quite literally, because light has a speed (186,000 miles per second), as we look out into the night sky, the farther out we look the farther back in time we see. And since the Universe has an age (our best current guess is just shy of 14 billion years), it has an observable limit. More Universe surely exists beyond the limit of our visibility some 45.7 billion light years away*...but we won't ever get to see it.
Not only that, but we won't personally get to see most bits of the universe that are inside the observable limit, simply because what's going on there "now" won't be visible to us til the light reaches us. A star 7,000 light years away from us could have ceased to exist yesterday, and we won't know it for another 7000+ years. To us, that star is still shining. Light and time, those phenomena easily detected by our senses, have set boundaries around us. Even though the geocentric theory of creation has been roundly debunked on several orders of magnitude, in one very important way it is still valid. The point of observation is, by definition, the center of the observable universe.
We still keep searching for ways to escape the box, though. We keep dreaming up new theories, testing and wringing new data from the stuff that makes up our physical reality. We sit at the center of the Universe, but the edges of it are right here as well, nested in the folds of the human mind.

*The Universe is expanding at an apparently increasing rate. This means that what we can see is farther away than the age of the Universe in years times the speed of light, because space keeps getting "bigger." Weird enough for ya yet?
