Scientists Turn Tequila into Diamonds
Scientists Turn Tequila into Diamonds
The key to the surprising discovery is tequila’s ratio of hydrogen, oxygen, and carbon, which lies within the “diamond growth region.” The resulting diamond films could have inexpensive commercial applications as electrical insulators, say researchers Javier Morales, Luis Miguel Apátiga, and Víctor Manuel Castaño from the National Autonomous University of Mexico (Morales is also with Nuevo León´s Autonomous University).
Originally, the scientists were experimenting with creating diamonds from organic solutions such as acetone, ethanol, and methanol. They found that diluting ethanol in water resulted in high quality diamond films. The scientists then noticed that the ideal compound of 40 percent ethanol and 60 percent water was similar to the proportion used in tequila.
“To dissipate any doubts, one morning on the way to the lab I bought a pocket-size bottle of cheap white tequila and we did some tests,” Apátiga said. “We were in doubt over whether the great amount of chemicals present in tequila, other than water and ethanol, would contaminate or obstruct the process, it turned out to be not so. The results were amazing, same as with the ethanol and water compound, we obtained almost spherical shaped diamonds of nanometric size. There is no doubt; tequila has the exact proportion of carbon, hydrogen and oxygen atoms necessary to form diamonds.”
Periods of healthy old age vary
Periods of healthy old age ‘vary’
The health of older Europeans varies widely between countries, even in those with longer life expectancies, a report has claimed.
The researchers collected data on life-expectancy, then surveyed older people from each country to find out whether they felt that illness had limited their ability to carry out normal activities.
This was used to calculate how many “healthy life years” a man and woman from each EU country could expect after their 50th birthday. In some cases, this revealed problems not immediately apparent by just looking at life expectancy charts.
Airline passenger restrained with duct tape
Airline passenger restrained with duct tape
An airline crew used duct tape to keep a passenger in her seat because they say she became unruly, fighting flight attendants and grabbing other passengers, forcing the flight to land in North Carolina.
Maria Esther Castillo of Oswego, N.Y., is due in court Thursday, charged with resisting arrest and interfering with the operations of a flight crew aboard United Airlines Flight 645, from Puerto Rico to Chicago.
Castillo, 45, struck a flight attendant on the buttocks with the back of her hand during Saturday\’s flight, FBI Special Agent Peter Carricato said in a criminal complaint filed in U.S. District Court in Charlotte. She also stood and fell onto the head of a blind passenger and later started pulling the person\’s hair, the complaint stated.
Lynx deodorant kills boy, 12
A 12-year-old boy collapsed and later died after using too much deodorant.

Derby Coroner’s Court heard that Daniel’s overuse of Lynx Vice in the confined space of the bathroom of his family’s home caused his heart to fail.
Pub row erupts after feces found in ice cream
Pub row erupts after feces found in ice cream
A bitter row has broken out between one of Sydney’s largest tourist pubs and a family of five who accused chefs of serving human excrement in their gelato after they complained about noise during a football match.
State government food minister Ian Macdonald confirmed on Wednesday that frozen fecal matter had been found in a serving of chocolate gelato offered to placate pub patron Steve Whyte and his wife Jessica, who became “violently ill” after eating it.
“The stench went through my nostrils, I retched and spat it into the napkin,” Jessica Whyte told the Daily Telegraph newspaper, recounting what local media are calling “gelati-gate.”
In this economy, even sex doesn’t sell
In this economy, even sex doesn’t sell
The women at Donna’s Ranch are crowded around the kitchen table on a warm summer night, dining on stir fry, tugging at thigh-high dresses, griping about depleted bank accounts. At this northeastern Nevada bordello, which marks a gravel road’s end, they woo grizzled truckers and weary travelers for a single reason: money.
Lately, the women don’t go home with much.
Signs of the economic free fall have cropped up in many of Nevada’s 25 or so legal brothels. The Mustang Ranch, for example, has a steady stream of customers, but the number of women vying for work has soared. Even a 74-year-old applied. This summer, the Shady Lady gave $50 gas cards to those who spent $300. The Moonlite Bunny Ranch offered extras to customers paying with their economic stimulus checks.
Here, 180 miles west of Salt Lake City, near the junction of Interstate 80 and Highway 93, Donna’s Ranch has seen its business plummet nearly 20%. More than three-quarters of its customers are long-haul truckers, and high fuel and food prices have drained them of “play money,” owner Geoff Arnold says. That cuts into pay for his 10-member staff and the “working girls.”
How to Permanently Delete Data from Your Hard Drive
How to Permanently Delete Data from Your Hard Drive
According to the New York Times, a basic privacy measure that is often overlooked is the proper destruction of data on hard drives. An ongoing study by British Telecom says that most people don’t realize that deleting a file doesn’t actually remove the data from a computer.
In fact, the BT research found that only 33 percent of second hand hard drives had been completely wiped clean. To ensure your drive doesn’t contain any personal data before you give it away or sell it, you need to reformat the hard drive or use digital shredding software if you want to completely eliminate all traces of data. In this post, we’ll show you how.
When it comes to data stored on your computer, deleting files doesn’t actually remove the data. File information is kept in a directory so that the operating system can find it. When you delete a file, all you are doing is removing it from the directory and flagging that part of the drive as being available for new data. Until that region is overwritten, the old data can be retrieved, in fact that’s how you can recover lost data. It’s also the way most file recovery programs work – they look for data on your hard drive that shouldn’t be there according to the directory and restore it.
