Economist Austan Goolsbee had a column in the NY Times last week looking at the economic rationale for why reality TV programming has become so popular these days. It goes well beyond the simple answer that it's cheap to produce. As Goolsbee notes, if that were the case, it would have caught on much earlier. Instead, the argument is that with the rise of satellite and cable TV adding many more options for people's viewing time (and you could argue plenty of other entertainment options as well), the pool from which network TV operators can expect to get viewers is shrinking, forcing them to search out cheaper programming.

However, a separate NY Times article may offer another potential reason (whether on purpose or not). It looks at a new study of what programs people record on DVRs and finds that people are less likely to record "timely" programs on their DVRs, preferring to watch them live. This includes the obvious things like news and sports -- but also reality TV programming. That's because who gets kicked off American Idol is likely to be talked about the next morning at work, and people want to make sure they've seen the latest so they can talk about it. That creates fewer incentives to record the program and watch it later. So, whether or not TV programming execs recognize it, reality TV programming may actually get more people watching, rather than skipping, commercials.

A solar-powered air conditioner doesn't do one much good during a Vermont winter, but rather than cranking on the heater (or huddling under the heated Hello Kitty mat) just to heat things up in a relatively small garage, a clever DIYer set out to concoct his own solar heater using scrap parts and a bit of free time. The solar wall was primarily built with black-painted soda cans, a wooden wall, plexiglass cover, and an inlet and outlet to channel the air around. The homegrown "solar furnace" captured the sunlight beaming onto the south side of the building, and as cool air found its way into the toasty cans and rose through drilled out portals, it managed to heat up a respectable 15-degrees Fahrenheit before escaping into the garage. The creator did note that his next attempt would sport a relocated inlet and be much larger in size, but if you're interested in putting a few in-the-way parts to good use next winter, be sure to hit the read link for a pictorial how-to.

Home Secretary John Reid is asking Apple and Sony, and other manufacturers, to join his crime fighting summit.

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.

Scientists have designed a new, interactive map of the spread of the avian flu virus (H5N1) that for the first time incorporates genetic, geographic and evolutionary information that may help predict where the next outbreak of the virus is likely to occur. In the process, they also tested hypotheses about the nature of specific strains of the virus that appear to be heading westward and have the ability to infect humans.

Adolescents who engage in one form of risky behavior, like drug or alcohol use, are likely to engage in other risky behaviors like self-harm, or having unprotected sex, but often these behaviors are not discussed during a medical or mental health exam. Now, a new study shows that a simple and brief screening measure called the adolescent risk inventory (ARI) can quickly identify the broad range of risk behaviors found among adolescents.

We've all heard the diehards claiming that the whales are the ones we should save, and thanks to an autonomous glider crafted by Webb Research, they're finally getting their wish. Recently, a trial was pursued in which a radio / satellite phone-equipped Slocum Glider was sent up to 200-meters beneath the depths in order to survey, pinpoint, and record location data for various whale pods swimming about. The device then surfaces and "phones home" the recently gathered information, which can then be disseminated out to ensure nearby vessels don't enter whale-packed territories. Jim Theriault of Defense Research and Development Canada, Dartmouth ran the experiment, and noted that this iteration of whale sensing and reporting improved on previous attempts by being uber-stealthy, featuring a remote data reporting system, and boasting a signal processor capable of tracking even the baleen whale's "lower-frequency call." Currently, the torpedo runs on batteries which last a month or so without needing a recharge, but future renditions are planned to scour the waters for "between five months and a year" by utilizing a special recharging gel. Look for these to hit your nearest ocean later this summer, and try not to be too alarmed when it surfaces beside your craft.

Clogged highways and frustratingly waiting while your gas needle plummets to empty usually doesn't conjure up thoughts of green, but it seems like these very roads could become the source of a lot more energy. Several recent student designs have proposed that major roadways be retrofitted with various forms of wind energy collection devices, ranging from overhead turbines that collect energy from quickly-moving cars below to barrier panels (pictured after the jump) that harness the wind from closely passing vehicles moving in opposite directions. Ideally, the wind energy could then be sent back out to the grid to power nearby communities, light-rail transportation systems, or even intelligent billboards. Of course, most of these ideas are still in the research phase, and even if proven feasible, we can't imagine the up-front costs (or inconveniences of installing these things) to be minor, but we're sure that government subsidies should be able to to lend a helping hand.
