You Asked: What makes the sound I hear when my stomach rumbles from being hungry? — Scott, Dagsboro, Delaware Marshall Answered: Digestion can be noisy. A doctor will often listen to your stomach with a stethoscope. Noise means that everything is OK. Your doctor is hearing the sounds of gases, liquids and food making their [...]

You Asked: I’ve noticed that my machine seems more sluggish on rainy days. Is it possible that a drop in barometric pressure impacts the efficiency of microelectronics? Or is this all in my head? — Roxanne, Atlanta, Georgia Marshall Answered: Interesting question. There are several things that could cause a machine to feel “sluggish”. The [...]

The New York Times reported on the growing number of tents and lean-tos in Fresno, Calif., in the article “Cities Deal With a Surge in Shantytowns.” It’s a throwback to the Hoovervilles of Depression-era America, writer Jesse McKinley says. McKinley clarifies that these shantytowns exist “on a far smaller scale” than Hoovervilles, but they’re becoming a very real part of the landscape in such places as Nashville, Olympia, Wash., and St. Petersburg, Fla.

It’s a grim reality. While some American families are dealing with foreclosures, some never had a McMansion to begin with. And perhaps the situation is most dire in Fresno, just judging from the numbers. Out of a city population of 500,000, nearly 2,000 homeless citizens have been counted. The city has more than three established encampments. Fresno officials hope to clear them and move the residents into permanent living areas.

Maybe it’s just really hopeful reporting or a bit of fairy dust, but McKinley’s piece didn’t leave me hanging my head, wondering where the justice is. There’s pride in the voices from the article, people who put in a day’s work and go home to a structure that they made from their own two hands. One man featured in the article, Guillermo Flores, assesses the conditions of his lean-to and says, “The only problem I have is the spiders.”

Liars have a hard time plying their trade these days. You can barely raise an eyebrow or try to tell Katie Couric that you’ve never used steroids without someone picking apart your facial movements for signs of deceit. Such is the world of microexpressions, which Josh and Chuck explored on their “Stuff You Should Know” podcast, as did our article by Tom Scheve.

Even if you could mummify your face with Botox injections to guard against fleeting microexpressions, you’d still have to cover for the increased breathing rate, pulse, blood pressure and perspiration that may accompany telling a bald-faced lie. That’s what polygraphs pick up.

Now sweaty lying people have even more to fear, according to Dave Johns’ story on Slate. The U.S. Department of Homeland Security is nosing around the idea of analyzing your unique stink for signs of deception.

Palm Island in Dubai is a giant man-made island: But how did they build it? The whole thing is constructed from stone and sand. But engineers had to solve a whole slew of problems in order to get the job done. Here are the details of the island’s construction: – Part 2 – Part 3 [...]

Darkness will hang over about 1,000 cities this Saturday night. But it won’t be in a sinister, Gotham sort of way. Instead, a hoped-for 1 billion people across the globe will cut their lights at 8:30 local time to call attention to climate change. The event, called Earth Hour and staged by the WWF, calls for turning off all unnecessary lights for one hour. Monuments like the Empire State Building, the Great Pyramids and the Acropolis will participate.

While Earth Hour is meant to be a symbolic gesture, a way to show support for taking action against global warming, it does raise some interesting questions about nighttime power use. Why are so many buildings lit up 24/7? Offices have different reasons for not hitting the switch regularly. It’s often about cosmetics: A building manager might think towers simply look better with each bright square accounted for.

The word on the street is that Toyota Motor Corp. is planning to develop a new small hybrid car to compete for sales with the Honda Insight. The Insight is the low-cost hybrid that Honda just began selling in the States for slightly less than $20,000. The new gas-electric hybrid from Toyota will come in the form of a spin-off of the Yaris model and is expected to be priced around 20 to 30 percent less than the current Toyota Prius hybrid.

The debut of the inexpensive Insight hybrid from Honda has put Toyota in a position where it has to react to stay competitive…and it seems as though it had better react quickly. According to Automotive News, Honda’s Insight hatchback, which launched in Japan last month, logged orders of 18,000 units in its first month, more than three times its monthly sales target of 5,000 units. In other words, the Insight is selling like hotcakes.

A big thank you to SYSK listener Ani (pronounced ah-nee) over in Madrid for sending us a link to a recent Economist article on a University of Essex study that found an optimistic outlook may be genetic.

For the most part humans tend to maintain an optimism bias; an unfounded belief (at least as far as the law of averages goes) that things will pan out well for us. There are also those among us who truly excel at irrationally processing the positive and patently ignoring the negative; we commonly refer to them as optimists.

Irrationality irks scientists like nothing else can, and so, of course, they’ve set about trying to get to the bottom of why optimists see things the way they do. Using our friend the Wonder Machine, New York University researchers conducting a 2007 study found that the area of the brain associated with clinical depression in humans activates differently in the skulls of optimists.
