Since the water carrying ability of saturated air goes up with temperature, there should be a trend toward heavier rainfall with temperature increases. Of course, places that are in a "rain shadow" like most deserts would not be expected to benefit as much as places near large bodies of water.

...to the one using the hammer, there is a tendency for everything to look like a nail. Identifying fMRI correlates may not actually indicate the number of cognitive components in play, any more than counting the number and location of gasoline stations tells us much detail of what people in a city are doing. At most, it gives us some useful hints.

I think most students who are savvy enough to use Coursera ought to be able to create a student-only email account for the purpose.

The only way this could work is if the electrodes can be made much,much thinner than paper thin, and even then they might irritate nearby tissue. It's a huge technical challenge. Better to use a smaller electrode surface area and train the patient to signal to the electrodes.

The topography of the zoning and building layout matter. Consider two neighborhoods which are 2-mile squares in shape. One neighborhood has a commercial district in a single corner, the other neighborhood has two such districts at opposite corners of its square. The second neighborhood may score twice as walkable, but what matters to the home's individual walkableness is how close it sits to one of those districts, since you presumably want to walk to the store and to an office in a corner that has a commercial district.

Choose a place you would like to walk, shop and work, then find a home located within a walking distance from those places, and you may have MANY good options, more than your zone-based averaging will reveal.

"The NSA cannot completely eliminate 'about' communications from its collection without also eliminating a significant portion of the 'to/from' communications that it seeks."

Almost all the US population and much of the rest of the world's people seen as.. just bycatch?

It's becoming plastiglomerate! See: http://www.geosociety.org/gsat...

One's understanding of science and theory formation in general is independent of whether a theory (even a true one) is believed. Only ideologues (see warming denial, global) would need to think otherwise.

The first rain storm should do it.

DARPA has a small implantable chip that will do what you need it to do, assuming the patient is truly fully awake. They have monkeys working a robotic arm with brain signals alone.

There is a variable angle change just after the initial turn away from the threat that allows the fly to be unpredictable. Otherwise the predator can predict the fly will evade directly away and anticipate where the fly will be. Very clever.

...that all cultures are equally to be valued. Otherwise, why not create more varieties of people with partial physical deficits, so as to have more such cultures?

See the semi-obligatory XKCD here.

The control groups should have been two other reading selections designed to bracket programming code reading: for example, reading mathematics, such as algebraic proofs, versus reading in an unfamiliar non-math vocabulary like a dense legal contract. It's possible that all would have looked similar, or that two but not three would have been similar, or all different. We just don't know.

And don't let me even get started on the fact that most fMRI studies use far too few subjects and then use absurd values for N like thousands of MRI mapped vertex points in a single subject to reach "significance" (a technique which would be considered a statistical cheat in any other field).

A story is told about ichthyologist David Scott Jordan. Jordan and a colleague were walking across campus one day when a student asked Dr. Jordan a question, which, upon answering, Jordan asked the student's name. Jordan's colleague asked him why he didn't remember his student's names. Jordan replied, "Every time I remember the name of a student, I forget the name of a fish!"
