That's what it might sound like if I had a tongue stud hitting my teeth. Maybe you've seen people with studs in their tongue clicking it up against their front teeth and a move known as playing. But it turns out that the habit may destroy some smiles.
University of Buffalo researchers noticed that local high school students who had a barbell<杠铃> type tongue stud commonly pushed the piercings against their teeth. Then they examined a 26 year-old patient at the school's dental clinich. She'd been complaining about a large gap that had developed between her two front teeth.7 years previously she got a tongue stud and everyday for 7 years she pushed that stud up against her teeth.
The researchers say tongues are strong and make sense that the force of playing will move teeth, even forcing them apart. The case was written up in the journal of clinical orthodontics<牙齿矫正学>.
Tongue piercings have also been associated with infections, chipped or broken teeth and gum<这里为 牙龈>trauma<外伤>. and the patient, she got braces <牙套>to push her teeth back together, which probably didn't look quite as cool as she thought the tongue stud was.

0807 60-second psych

Anyone familiar with psychology has probably heard a statement like this, a significant percentage of male and female undergraduates displayed 'X' when prompted by 'Y', and typically the conclusion of the study something like so humans display 'X' in the presence of 'Y'. Well, Taking the behavior of undergrads extending it to all of the humanity is an intriguing leap, right? Well, to be fair, for research purposes, undergrads are cheap and accessible, but as noted by the blogger Headcase, such terms are better used to describe a hot date rather than good data.

Well, a group from the University of British Columbia recently published enormous meta-analysis on the danger of assuming that all the humanity closely matches the behaviors of 20 something college students. They cite evidence that between 2003 and 2007 undergrads made up 80 percent of study subjects in 6 top psychology journals, and 96 percent of all psychology samples come from countries that make up only 12 percent of the world's population. They call this the weird population, and that stands for Western Educated Industrialized Rich Democratic and say that they are the least representative populations one could find, for generalizing about humans.

The researchers found huge variability between global populations along measures of motivation,  self-perception, reasoning, heritability of IQ, and even visual perception, for instance, the Miller-Layer visual illusion which shows two lines of equal lengths where one is often perceived at least by the American undergrads as longer than the other, is actually not an illusion at all. For the San foragers of the Kalahari. The authors also noted points of similarity like this one. In 37 populations, males tend to ranked physical attractivenss of mates to be more important than do females. But the main plea for the researchers is that far too often, the so called weird populations, are actually the 'outliers'. And psychologists need to be less cavalier but labeling some behavoir as human nature, just based on the desires, emotions and culture of a group of 19-year co-eds.

0808 60-second Earth

The ancient inhabitants in Amazonia knew how to keep fragile soils fertile and may have found a way to combat present day climate change, that technique---biochar, or any plant or animal ways turn to charcoal and put back in the ground.

Studies suggest as much as 900 million metric tons of carbon a year could be locked up this way, and improve this soil's ability to grow crops. That's nearly 20 percent of current CO2 emissions from burning fossil fuels. A new study shows that biochar could have an impact on agriculture's other greenhouse gas emission. Nitric oxide or laughing gas which is no laughing matter when it comes to climate change. Biochar applied Australian fields and left for a number of months, cuts such emissions by more than 70 percent. Of course biochar is no panacea. Some studies suggest biochar accelerate microbial decomposition of organic matter into dread CO2, in places like boreal forest. But perhaps charcoal is a better fertilizer than fuel for barbecues. The terra preta soils of Brazil, are still being farmed centuries after the biochar was added.

8/11：Almost a Million Years Added for Earliest Human Ancestor Stone Tool Use and Meat Eating

原文选中后可见：
There’s nothing like a good steak. And our Australopithecus afarensis ancestors apparently felt the same way. Because new discoveries from Ethiopia show that what was likely the species of the famous fossil Lucy used stone tools to butcher meat from big mammals—about 3.4 million years ago. That’s a million years earlier than our best previous evidence for human ancestor stone tool use and meat eating. The finding appears on the cover of the journal Nature.

The research team found two fossil bones with cut and scrape marks, signs of meat carving. One bone was a piece of rib from a cow-sized mammal; the other, a leg bone fragment from a mammal the size of a goat. The bones also had percussion marks, sustained while Lucy’s friends smashed the bones to get at the marrow.

It looks like the ancient tool users collected stones that happened to have shapes conducive to butchering, the way kids select particular stones with good potential to skip on water. But future expeditions will look for evidence for any attempts at shaping stones into kitchen utensils. Because after 3.4 million years, Lucy and her fellow afarensis keep surprising us.
