What Most People Don’t Know
Ken Michener’s tooth had been hurting off and on for months, and the pain was intense one Monday night in August. So Michener, 31, of Naperville, Illinois, who worked night shifts at a company that manufactures vitamins and dietary supplements, left at 3 a.m., halfway through his shift. At home, he tossed and turned. By the next afternoon, he’d found an oral surgeon to pull his sore molar, and started taking antibiotics to beat the bacterial infection and reduce the swelling. They did neither. By Friday, Michener was still hurting, and his left cheek bulged. At a local hospital, his oral surgeon removed another tooth, drained some pus, gave him painkillers and more antibiotics, and checked him into intensive care.
By the following Monday, when Michener was rushed by ambulance to Loyola University Medical Center, in suburban Chicago, his cheek was so swollen that he couldn’t open his left eye. The infection had invaded the muscles that open the jaw, causing his jaw to clamp shut. It had also spread to Michener’s neck and was squeezing his airway. He couldn’t open his mouth, couldn’t speak and, despite a breathing tube designed to help, struggled to draw each breath.

Hockey players, rejoice! A team of University of Alberta researchers has created technology to regrow teeth–the first time scientists have been able to reform human dental tissue.
Using low-intensity pulsed ultrasound (LIPUS), Dr. Tarak El-Bialy from the Faculty of Medicine and Dentistry and Dr. Jie Chen and Dr. Ying Tsui from the Faculty of Engineering have created a miniaturized system-on-a-chip that offers a non-invasive and novel way to stimulate jaw growth and dental tissue healing.
“It’s very exciting because we have shown the results and actually have something you can touch and feel that will impact the health of people in Canada and throughout the world,” said Chen, who works out of the Department of Electrical and Computer Engineering and the National Institute for Nanotechnology.
The wireless design of the ultrasound transducer means the miniscule device will be able to fit comfortably inside a patient’s mouth while packed in biocompatible materials. The unit will be easily mounted on an orthodontic or “braces” bracket or even a plastic removable crown. The team also designed an energy sensor that will ensure the LIPUS power is reaching the target area of the teeth roots within the bone. TEC Edmonton, the U of A’s exclusive tech transfer service provider, filed the first patent recently in the U.S. Currently, the research team is finishing the system-on-a-chip and hopes to complete the miniaturized device by next year.

Whilst there are plenty of ‘low tech’ solutions to stop…err…conception, there is now a preventative prophylactic apropos for an EcoGeek in the works. The remote control, implanted device will allow users to ‘press pause’ on their sperm. (although it doesn’t mention whether a ‘rewind’ function is in the works). The device has been developed by Australian scientists, and could herald a new dawn of even more convenient contraception for men, which has the potential to keep population growth under control more effectively.
A surgeon inserts a silicon chip into the vas deferens. The fob sends out RF waves, just like the key to your car. The silicon chip converts the RF into acoustic waves, which in turn induce movement in the material, allowing it to expand and seal the tube. Sending another pulse from the key fob lets the material contract allowing sperm to pass.However, to avoid ‘cross talk’ with say… your cordless phone, WiFi or bluetooth…. ultrahigh frequencies are used, combined with sophisticated coding, to make sure that no mistakes can occur.
All they need to do now, is integrate a button to turn off the lights so you can save electricity.

In addition to brushing and flossing, a healthful diet (with natural or added fluoride) protects teeth from decay and keeps the gums healthy. Read on to discover how to keep your smile safe and strong.
Tooth decay (cavities and dental caries) and gum disease are caused by colonies of bacteria that constantly coat the teeth with a sticky film called plaque. If plaque is not brushed away, these bacteria break down the sugars and starches in foods to produce acids that wear away the tooth enamel. The plaque also hardens into tartar, which can lead to gum inflammation, or gingivitis.
A well-balanced diet provides the minerals, vitamins, and other nutrients essential for healthy teeth and gums. Fluoride, occurring naturally in foods and water, or added to the water supply, can be a powerful tool in fighting decay. It can reduce the rate of cavities by as much as 60 percent.

Recipe for Disaster
Ninety percent of Americans’ household food budget is spent on processed foods, the majority of which are filled with additives and stripped of nutrients. Discover which common ingredients in the foods you eat pose the greatest risk to your health.
Grab the broccoli with cheese sauce from the freezer, the box of instant rice pilaf from the pantry, or the hot dogs from your fridge and squint at the ingredient list’s fine print. You’ll likely find food additives in every one.
Is this healthy? Compared to the foods our bodies were built to eat, definitely not.
Processed, packaged foods have almost completely taken over the diet of Americans. In fact, nearly 90 percent of our household food budget is spent on processed foods, according to industry estimates. Read the rest of this entry »

What if you could convince people to trust you and take risks for you with just a few drops of liquid surreptitiously placed in their water? There would be no drunkenness, no rufie-esque glazed eyes: just pure, human trust created via chemicals. The person wouldn’t even know they’d been dosed. A study coming out tomorrow in the journal Neuron explains how this scenario is possible today, with just a small dose of the brain chemical oxytocin.
Oxytocin is a chemical associated with many of the “pleasurable” feelings you have, from basic trust, to love and orgasm. Researchers in Switzerland theorized that people playing social trust games might change their behaviors if given doses of oxytocin, since the chemical might artificially enhance their willingness to trust someone. Indeed, they were right: subjects dosed with Oxytocin were willing to trust people even after they’d been explicitly told that those people had behaved in untrustworthy ways in the past. People who had not been dosed did not trust the “untrustworthy” people.
