Drink brewed tea to protect your teeth

Wednesday, November 26th, 2008

Forget lattes and fresh lime juice, the best thing to drink is brewed tea, for it has no erosive effect on teeth and it’s antioxidants provide health benefits, according to a new research.

Refined sugars and acids found in soda and citrus juice promote tooth erosion, which wears away the hard part of the teeth, or the enamel. Once tooth enamel is lost, it’s gone forever.

However, brewed tea is a beverage that does not produce such irreversible results.

Apart from tasting good, brewed tea has many health benefits. Tea is loaded with natural antioxidants, which are thought to decrease incidence of cancer, cardiovascular disease, and diabetes.

For the study, lead author Mohamed A. Bassiouny, DMD, BDS, MSc, PhD, compared green and black tea to soda and orange juice in terms of their short- and long-term erosive effect on human teeth.

The study found that the erosive effect of tea was similar to that of water, which has no erosive effect. And, when comparing green versus black, he discovered that there is a better option among those as well.

“When we look at tea and read about the benefits, it’s amazing-not because green tea is ‘the in thing’-but because there are advantages,” Bassiouny said.

He added that much research done overseas, in countries such as Japan and Europe, found that green tea was identified to being superior over black due to its natural flavonoids (plant nutrients) and antioxidants.

Experts suggest drinking drink tea without additives such as milk, lemon, or sugar because they combine with tea’s natural flavonoids and decrease the benefits.

The also suggest to stay away from prepackaged iced teas because they contain citric acid and high amounts of sugars. It does not matter whether the tea is warm or cold-as long as it is home brewed without additives.

Kenton Ross, DMD, FAGD, AGD spokesperson, sees patients’ erosion problems on a daily basis in his practice. “This study clearly shows that brewed teas resulted in dramatically less enamel loss than soft drinks and acidic juices. I would highly recommend patients choose tea as an alternative to more erosive drinks like soda and fruit juice.”

The study is published in the July/August issue of General Dentistry, the clinical, peer-reviewed journal of the Academy of General Dentistry (AGD).

Broadway’s “Great White Way” goes green

Wednesday, November 26th, 2008

Marquees in New York City’s Broadway theater district will go “green” this year as part of a plan to save energy and the environment.

Broadway’s “Great White Way,” nicknamed for the many marquee and billboard lights that flood the theater district with light, will soon be the “Great Green Way,” New York City Mayor Michael Bloomberg said at a news conference at the Eugene O’Neill Theater to launch the initiative.

“By this time next year, the lights on Broadway will burn just as bright, but the energy bills and our city’s carbon output will be lower,” Bloomberg said.

Already, 10 Broadway theaters have changed 10,000 exterior and interior bulbs to more energy efficient compact fluorescent bulbs as part of the initiative organized by the mayor, the Broadway League and the National Resources Defense Council.

Broadway theaters plan to do everything from washing their costumes in cold water to producing and disposing of sets in a more environmentally friendly way to lower the theater industry’s carbon footprint, organizers said.

Several characters from Broadway shows made cameo appearances in support of the plan to lower carbon emissions.

“Higher… bad! Lower… good!” roared the character “Monster” from the Broadway musical “Young Frankenstein,” who appeared with “Avenue Q’s” Nicky and “Wicked’s” Elphaba.

Broadway shows are a major attraction for visitors to New York City and shows sold 12.27 million tickets in the 2007-2008 season, contributing $5.1 billion to the city’s economy and supporting 44,000 local jobs, according to the mayor’s office.

‘India losing its medicinal plant species’

Wednesday, November 26th, 2008

Key species of medicinal plants in India are under threat because of over-collection for supply to domestic and foreign markets, the latest report on medicinal plants by conservation groups, IUCN and TRAFFIC, suggests.

The research focusing on seven species of medicinal plants found in Asia shows that India is emerging a major destination for five plant species, including Elephants Foot (Dioscorea deltoidea), Jatamansi (Nardostachys grandiflora), Kutki (Picrorhiza kurrooa), Red Sanders (Pterocarpus santalinus) and Snakeroot (Rauvolfia serpentina).

Many of the medicinal plants in trade in India are collected in the high Himalayan regions of neighbouring Nepal, where collection of species such as Jatamansi and Kutki runs to hundreds of tonnes of rhizomes, harvested by thousands of collectors who supplied them to middlemen and to large-scale wholesalers in Nepal and India, suggests the finding.

Raw material are often transported to wholesale markets in Delhi, Amritsar and Kolkata for onward sale, says the report.

With regard to trade in Himalayan medicinal plants, most though not all, roads lead to India, which is both a major manufacturing centre and end consumer market, says TRAFFIC’s Teresa Mulliken, an author of the report.

Besides, the use of wild-plant species form the basis of traditional medicinal systems practices in Asia, particularly traditional Chinese, Ayurveda, Siddha, Unani and Tibetan medicines.

Students Share Exams Online

Wednesday, November 26th, 2008

Photos. Music. Irrelevant video clips. For years, college students have shared them all on the Internet. Now, they’re using the same medium to swap notes, tests, and quizzesa trend that has caught the wary eye of profs whose materials are being uploaded and school officials who worry about cheating.

In recent years, several Web sites have emerged that encourage students to submit their schoolwork for mass consumption. They collect old exams (PostYourTest.com, Exams101.com), class notes (NoteCentric.com), study guides (HowIGotAnA.com) and all of the above (CourseHero.com). Some of the largest sites claim thousands of users around the world and say they’re making money.

High-Tech “Test Files”

Students from an earlier generation will recognize the note-sharing sites as a high-tech twist on an old college practice. Fraternities and sororities have long maintained “test files,” where younger members study from older members’ course work. Non-Greeks, of course, have criticized the practice, saying it gives the frat and sorority members an unfair advantage.

Indeed, Demir Oral, a Web designer living in San Diego, says he launched the Post Your Test site to level the playing field. “This kind of service should be available to anyone, at any time,” he says.

Oral supports his site using Google ads, which generate “a decent amount” of revenue, he says. But he’s forecasting growth: Since July, the site’s member count has more than doubled, to 1,000, and it currently hosts between 600 and 700 exams. A few weeks ago, Oral received his first international submission, from Sultan Qaboos University in Oman. “People are starting to realize the uniqueness of our database,” he says. “It’s a very exciting time.”

Backlash from Teachers and Students

Not everyone is buying into the hype, though. Because professors don’t know when their exams are being posted, they could unwittingly re-use a question students have seen online, says Jim Posakony, a biology professor and former chairman of the academic senate at the University of California at San Diego, where teachers have organized to keep their exams off Post Your Test.

Having easy access to quizzes and notes could also reward laziness, says Nichole Mikko-Causby, a senior at the University of Georgia. “The whole trend seems to be more about getting the grade than improving critical thinking skills,” she says, noting that she’s visited Course Hero but never used it. “It kind of cheapens my degree.”

Kasuni Kotelawala, a sophomore at University of California, San Diego, is far more satisfied. Because her biology professor hadn’t spent much time discussing the most recent class midterm exam — let alone distributing a practice test — Kotelawala wasn’t sure how to study. But after reviewing one of her professor’s past exams on Post Your Test, she says she knew what to expect. “It definitely helped,” she says.

Copyright Issues

But was it legal? Like novels and artwork, exams are intellectual property, meaning they’re owned by the universities or the professors who wrote them, and they’re protected under copyright laws. Publishing them without permission is treading on “legal thin ice,” says Bob Clarida, a copyright lawyer at Cowan, Liebowitz & Latman, in New York.

Faculty members at UCSD raised this concern last August, after representatives from Post Your Test visited campus. To promote the site, the reps had offered Starbucks gift cards in exchange for student exams, a gimmick that left some professors “very unhappy,” says Posakony.

With Posakony’s help, roughly 150 professors organized. They told Oral to take their old exams off Post Your Test and to reject future submissions bearing their names. He wasn’t thrilled, but he obliged. “We always follow the Digital Millennium Copyright Act,” Oral says, referencing the law that protects online service providers, like Post Your Test and YouTube, as long as they honor requests to take down unlawful uploads.

Support from Faculty Members

Yet for every UCSD professor who rallied against Post Your Test, there was another who dissented. During the brouhaha, many faculty members came forward saying they had “no problem” with the site, especially if it was helping students review more effectively, says Posakony.

Oral also positions his site as a learning tool for academic professionals. Writing good exam questions can be just as challenging as answering them, he says. On Post Your Test, professors can sift through hundreds of subject-specific tests and quizzes, and alter their own work accordingly.

Other sites sell different strengths. HowIGotAnA.com (also known as Einstein’s Notes), which exclusively serves the University of Florida, offers class-specific study kits — including lecture notes, flash cards, practice exams and more — for roughly $20 per semester. During an exam week, the site can sell between 75 and 100 packets per day, says Torey Greenwald, one of the site’s editors.

Course Hero, which bills itself as “the social learning network,” uses a Facebook application to connect students who are taking similar classes. Since its January launch, the site says it has amassed more than a million study aids — including notes, tests, quizzes, and textbook solutions — and roughly 300,000 fans on Facebook. “We’re trying to create an environment where students can learn from each other,” says Andrew Grauer, who left Cornell University for a semester to develop Course Hero.

Unfair Advantage?

The sites also raise ethical issues. Many schools’ academic honor codes bar the gaining of “unauthorized advantage” in preparing papers and studying for exams. But whether using note- and test-sharing sites violates that code is unclear.

Donald McCabe, a management professor at Rutgers Business School who has done extensive research on academic cheating, says he “doesn’t see anything unethical on the part of the students” who use note- and test-sharing sites. Old exams are useful study tools, he says. And in an age where almost anything can wind up online, professors should know better than to re-use questions. “It’s a little discouraging, and it might be mean a little more work for us,” he says. “But you can’t fault the students for it.”

That’s good news for Grauer, who hopes that all of academia will tolerate — and eventually embrace — Course Hero. “The more resources we get, the more useful we’ll be,” he says. “Students will really benefit from this.” And Grauer should know: He’ll be one of them through May.

Himalayan oregano may help eradicate MRSA superbug

Tuesday, November 25th, 2008

A natural oil from Himalayan oregano can help wipe out deadly hospital superbug MRSA, according to a new research.

Boffins have discovered that the herb, commonly used in cooking, could eradicate the deadly infection from hospital wards.

Tiny quantities of carvacrol, a naturally occurring compound in Himalyan oregano, were found to be a more effective antimicrobial agent than 18 pharmaceutical drugs, investigators found.

University of the West of England researchers, working with partners in India, said carvacrol, which contains potent anti-fungal and anti-bacterial properties, has a range of medicinal uses.

The discovery could lead to a new defence in the fight against hospital infection.

Carvacrol can sterilise septic water, kill giardia, treat fungal infections such as candida and rivals pharmaceutical antibiotics such as streptomycin and penicillin in its ability to eliminate microbes, reports the Telegraph.

Research into the medicinal properties of oregano has been led by Biolaya Organics, a company that specialises in the conservation and sustainable production of Himalayan medicinal herbs.

Preliminary research into the oil found that tiny doses are capable of wiping out fungi and bacteria, including MRSA.

Scientists found that the oil still works at boiling temperature, meaning it could be used for disinfecting hospital sheets. Its vapour is equally effective and could be turned into an antibacterial spray.

Heron said: “Himalayan oregano oil kills MRSA at dilution’s of less than 1 to 1000 and the antimicrobial properties, unlike most conventional antibacterial agents, are not affected by heat treatment. Once we have completed our research and published a paper, we aim to find additional partners to work together with to manufacture hand soaps, multi-purpose antibacterial wipes and other products for use in hospitals as a preventative against MRSA.”

Online falls off the line

Tuesday, November 25th, 2008

We all know online advertising decelerated in the third quarter, but how bad was the slowdown? To find out, a blogger on TechCrunch added up the online advertising revenues for the four major players, Google, Yahoo!, Microsoft, and AOL that together account for the majority of online advertising.For the purposes of this analysis, the website took the total advertising revenues from both Google and Yahoo!, including their network revenues paid to affiliates, the online revenues reported by Microsoft, and only the advertising portion of AOL’s revenues.

These four serve as good proxy for the overall online advertising market. Below are the absolute revenue numbers, broken down by company:.

Virgin offers Internet access in-flight

Tuesday, November 25th, 2008

Virgin America plans to become the latest airline to offer in-flight Wi-Fi Internet.

The service, named as Gogo, lets passengers browse the Web, use e-mail and instant messaging, download video and connect to secure networks through three wireless access points on the plane.

The San Francisco-based carrier has scheduled the service for one Airbus A320 aircraft, joining American Airlines as the only carriers in the world to offer full Internet access.

With two carriers offering the service commercially, in-flight Internet is making a serious comeback after a two-year period of dormancy.

If Virgin America’s test flight is deemed successful after about a week of flying, the airline will expand the service to 24 other planes in its fleet by mid-2009.
