Bonnie Bassler: How bacteria "talk"
Hmm interesting the simplified way Bonnie describes the quorum systems makes me think of how computer systems work. The standing ovation at the end was very much deserved as you can see how this work would lead directly to a saving human lives. I would think thank while bacteria mihgt com up with a wy around this, it's somewhat unlikely to happen anytime soon, as all bacteria use the same messaging systems, which would have to be a very significant part of the DNA of a bacterium, and one which is highly integral.

Robert Full: Robots inspired by cockroach ingenuity
To those ID'ers out there, please figure out what it is ID is contributing. An entire topic designed to disprove one theory, but not giving us another viable scientific theory in replacement is pretty lame. ID'ers aren't adding to the overall knowledge, you are just being noise. I liked this talk immensely, I was very impressed with the details of the foot of the Gecko. I was a bit more interested in the Gecko's foot underwater, why doesn't the vanderwals force apply to the water molecules?

Charles Elachi: The story behind the Mars Rovers
That's a bit short sighted felix, leaving this planet to explore other planets, also gives us more information about our own planet. It might cost a huge amount (relative to amounts you and I are used to), it's not like probes going to other planets or through out our system, are the majority of what we spend money putting into space. In fact without this exploration, life today in Western countries would be very different. Imagine not having our Earth orbit set of satellites. We spend a huge amount of money sending those satellites to space, ( I would bet far more than our current probes cost us,) and operation of those satellites is also expensive. Systems here on Earth monitor those satellites, people around the clock are monitoring those monitoring systems. So for all the probes we send outside Earth orbit, there are hundreds of satellites aiming at Earth, helping us study this planet. I for one, am amazed how cheap sending Mars probes has become. I am also in awe of the JPL crew, forget the landing aspect, they manage to launch these probes, and get them to Mars. Even if only 1 in 100 probes managed to actually land on Mars, I'd be super impressed still.

Joshua Klein: A thought experiment on the intelligence of crows
I have two cats, one who is an avid hunter of Crows. Although mostly she only catches crows that get pushed out of the nest. The trees around my house are full of crows nesting, and every year they get extremely mad when they see her outside, during their breeding times. Yesterday she was out and had found a baby crow on the ground (most likely,) and was trying to bring the crow back into the house, but 3 adult crows were standing in front of the door, and keeping her at bay. They knew damn well if she made it into the house there was no hope for the baby crow. (Not much anyway, unless crows had figured out how to get the nestling back into the nest.) The crows are constantly dive bombing her, which they found out to their horror (and my shock,) she is waiting for this, and I've seen her pluck more than one crow out of the air while they are dive bombing her. This usually stops the crows for a while. Also in my neighborhood there are two groups of crows, that have little ritualized fights on the street, a couple crows will land on the street, and caw at each other, fluffing up their feathers, and spread their wings. While other crows on the telephone wires above will join in the cawing. I can't attest to this behavior being on going, but I have seen it once. No doubt there are two groups and the groups have divided their territory at the road though, often you'll see one crow from one side of the street, being intercepted by crows from the opposite side..
