Cavities – A Thing of the Past? – Possibly

Time reports –

Dentists may want to make note of a new molecule called Keep 32. It’s called that because the molecule seems to have the capabilities to help you keep all 32 of your teeth in your mouth and potentially make cavities — and maybe dentists — a thing of the past. The chemical was designed by scientists in Chile who seemingly have a vendetta against dentists bacteria. In laboratory tests, Keep 32 was able to wipe out all the bacteria that cause cavities in about 60 seconds. The molecule targets the bacteria known as streptococcus mutans, which keeps dentists in business by turning sugar into lactic acid, which in turn erodes tooth enamel. Once the streptococcus mutans is eradicated, mouths stay cavity-proof for several hours. The product has been developed and researched for seven years and is now moving into testing on humans. Once Keep 32?s efficacy and safety are proven, it could make its way into the market within 14 to 18 months, according to researchers José Córdoba from Yale University and Erich Astudillo from the University of Chile quoted in the Daily Mail. The Chilean website Diario Financiero Online reports that the pair have a provisional patent on the molecule and are looking for funding for their human trials.

Some Wounded Civil War Soldiers Glowed In The Dark

Mental_floss reported –

Some of the Shiloh soldiers sat in the mud for two rainy days and nights waiting for the medics to get around to them. As dusk fell the first night, some of them noticed something very strange: their wounds were glowing, casting a faint light into the darkness of the battlefield. Even stranger, when the troops were eventually moved to field hospitals, those whose wounds glowed had a better survival rate and had their wounds heal more quickly and cleanly than their unilluminated brothers-in-arms. The seemingly protective effect of the mysterious light earned it the nickname “Angel’s Glow.”

College Student Wears Same Jeans Every Day For 15 Months

CTV.ca reports-

A University of Alberta student didn’t wash a pair of skinny jeans for 15 months and science says the fashion trend is safe, but maybe a tad smelly. Josh Le wore the same pair of jeans to break in the raw denim, so it would wrap the contours of his body, leaving distinct wear lines.

He had his textile professor test the jeans for bacteria before washing them for the first time. The results showed high counts of five different kinds of bacteria, but nothing in the range of being considered a health hazard. Raw denim is not washed or treated when it is manufactured. A current trend is to wear the dark indigo jeans without washing them to allow the indigo to wear out in the fabric. After the jeans are washed, they leave a unique pattern based on their owner’s body. Le said some friends were “grossed out” by his experiment, but others thought it was interesting. “Some people really liked it, but some people were completely grossed out by it,” he told The Canadian Press. “I was able to meet a lot more people and have a lot of good conversations. It was like, ‘hey, nice jeans.”‘ When his jeans got a bit funky smelling, Le’s solution was to put them in the freezer. “There were times when it had a bad odour, like in the seventh month,” he said. “That’s when I threw it in the freezer and magically when it came out it was odourless.”
