Palm Trees Are Not Actually Trees

palmsListening to the podcast 99% Invisible I learned that palm trees are not actually trees. They are kind of a super grass, according to Jared Farmer who wrote Trees in Paradise: A California History. From the podcast, “palm trees don’t make bark or branches. If you cut them down you won’t find any rings in the trunk, all their roots grow in a compact ball…” This is an interesting story about palms in California and how demand has caused some mature trees to sell for as much as $20,000. Also great podcast.”

Super Animals – Tardigrades!

supertardiThe animal world has it’s own super hero, Tardigrades a.k.a water bears! Just like Superman, they are able to withstand extreme temperatures, radiation, extreme pressures! According to wikipedia they “can survive in extreme environments. For example, they can withstand temperatures from just above absolute zero to well above the boiling point of water (100°C), pressures about six times greater than those found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a human, and the vacuum of outer space. They can go without food or water for more than 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.” And they look crazy weird, like a cross between a caterpillar and a bear. If only they weren’t microscpic, they could be the next Sea Monkeys!

In this video, Hank Green gives us the low down on these creatures.

World’s Largest Cave Video Fly Through

HangSonDoongRan across this video of a quad copter tour of the large sinkhole part of the Hang Son Doong cave in Vietnam. Imagine the size of the room this area made before the roof collapsed! I realized I read the National Geographic article a few years ago, it has better pictures of the interior portions of the cave.

Infect me!

In our modern obsession of cleanliness and ubiquitous anti-bacterial soaps and hand sanitizers, we may have upset the unseen balance in our bodies. Is it possible to be TOO clean? Have we inadvertently scrubbed away the GOOD bacteria that make us healthy.

This NY Times article covers research into the five pounds of GOOD bacteria that live on and in our bodies.

Electric Cars and Hybrids Not So Economical

One of the touted benefits of electric vehicles is the fuel cost savings, but it appears that’s not necessarily the case according to Edmunds. Aside from the high purchase cost, a gas sipping Aveo is considerably much cheaper to operate than a Prius! And depending on how the electricity is generated used to charge the Prius, they may not be any better for the environment.

… consumers could see that at 1,250 miles a month, a 2010 Toyota Prius would cost, on a national average, $67 a month at the pump, while an electric Mini E would cost $49 a month to “fill” from a 220-volt charger in the consumer’s garage; the monthly gasoline bill for a four-cylinder Chevrolet Aveo would be $11, and a 2011 Chevrolet Volt – running on gas and electricity – would cost $54.

Western Diet most unhealthy

Michael Pollan writes in his book, In Defense of Food that “we shouldn’t allow ourselves to be intimidated by studies of new reports or especially food labeling. Humans can thrive on all sorts of diets. Some live healthy lives on nothing but cattle or seafood. In fact, he says, there’s only one diet that has consistently proved hazardous to our health.”

It’s actually, you know, people who have done the sort of ethnographic research around food have found this astonishing array of different traditional diets on which people have been extremely healthy. But there is one diet that it appears that we are poorly adapted to, and that is what we call the western diet.

And this diet makes people fat. It makes them diabetic. It gives them heart disease. It gives them an assortment of cancers. It’s just very toxic to our bodies.

Some of his rules for eating healthy are:

…don’t eat anything that doesn’t rot, don’t eat anything your grandmother wouldn’t recognize, don’t eat anything that has an unfamiliar, unpronounceable name, don’t eat anything with high fructose corn syrup, don’t eat food that features health claims on their labels.

The following interview on the radio show with a Nutrition Expert helps reinforce Pollan’s claims.

Subliminal Advertising was a hoax

According to Mark Crispin Miller, a professor of media ecology at New York University, the original revelation of subliminal advertising effects was a hoax.

In 1957, an enterprising marketing researcher named James Vicary announced to a breathless world that he had conducted an experiment in a movie theater in Fort Lee, New Jersey during screenings of the William Holden picture, Picnic. Vicary claimed that what he had done was to flash subliminal inducements during the screening of the film telling people to drink Coca Cola or to eat popcorn. His claim was that those subliminal flashes had actually increased sales of those items at the concession stand in the theater by some 38 percent.

This announcement took the country by [LAUGHING] storm. People basically freaked out over it. The networks swore they would never engage in practices like this. The New York State Senate passed a law against this kind of thing. Aldous Huxley appeared on The Mike Wallace Show [LAUGHS] and referred to it as something far worse than anything he’d imagined in Brave New World. It was quite a to do.

And the irony is that it turned out that Vicary had made the whole thing up.

The Brain uses 20% of body’s energy

“Although the brain accounts for less than 2% of a person’s weight, it consumes 20% of the body’s energy.”

34 words for do-do

I caught a very interesting lecture by Stephen Pinker author of The Stuff of Thought: Language as a Window into Human Nature on CSPAN this weekend. Pinker discussed some of the interesting or in his words crazy aspects of our language. Such as why we use terms like underground and underwater when we mean surrounded by ground or water. He also delved into his theories as to why we use profanity. He says that when we use profanity, it triggers a unique part of our brain. And his research determined there are 34 words in the english language for feces.
