No more fillings? Gel regenerates teeth

Dentists could soon hang up their drills. A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month, according to a new study in the journal ACS Nano. This technology is the first of its kind. The new gel or thin film could eliminate the need to fill painful cavities or drill deep into the root canal of an infected tooth. "It's not like toothpaste," which prevent cavities, said Nadia Benkirane-Jessel, a scientist at the Institut National de la Sante et de la Recherche Medicale and a co-author of a recent paper. "Here we are really trying to control cavities (after they develop)." Drilling teeth and filling them is safe...

China hosts first Robot Olympics

The World’s first International Humanoid Robots Olympic Games kicked off on June 21, in China’s Harbin’s Institute of Technology. Two years after hosting a memorable edition of the human Olympic Games, China becomes the first country to host an Olympics dedicated to humanoid robots. Nineteen teams, from China, United States, Japan, South Korea or Germany have brought their best robots to compete in this historic three-day event. To enter the competition, robots had to be less than 60 cm long, and have a human shape, with a head, two arms and two legs. Just like in the real Olympic Games, the sporty robots had to compete in multiple challenges, 24 to be exact, ranging from boxing, to weight-lifting, dancing, or sprint. But there are also some unusual domestic events, like cleaning or...

How to hold your new iPhone 4

Apple has released official advice for iPhone 4 owners to overcome the problem of the device losing signal when held by the lower left corner.Steve Jobs responded to a query about the problem from one owner by saying: "Just avoid holding it in that way." Except that it seems that Apple themselves have got it wrong and have gotten to grips with how to hold the new phone.Well it seems that while us mere mortals will have to settle for buying a rubber outer casing in order to ensure that we can continue to have a reasonable signal, one Intergalactic user has figured it out....I wonder what price plan he has got?

Make your own micro SIM

We've finally found ourselves a solid, confirmed shot of a micro SIM in the wild, thanks to an FCC filing from Lok8u -- the company that just inked a deal with T-Mobile -- that shows the innards of its GPS watch torn asunder. Over on the right there is one of the micro SIMs in question, and as you can clearly make out, the contact pad is identical to the one you'd find on a traditional SIM. In other words, if you were really hard up to get that iPad or iPhone up and running on a network that isn't providing micros, you could probably shoehorn a traditional SIM in there with a little elbow grease and handiwork, which happily matches up with information we've been hearing from several contacts of ours. Who knew Lok8u would be so important in...

Rome gets hotel made from rubbish

Environmental campaigners have built a temporary hotel largely from rubbish in the Italian capital, Rome, to raise awareness of European beach pollution.Save the Beach Hotel, taking guests for four days only, is adorned with debris from the world's beaches.Its five rooms and reception are lined with 12 tonnes of rubbish, including toys, cans, car exhaust pipes.Danish supermodel Helena Christensen, who has stayed at the hotel, said it was a striking work of art."When you're inside the house, there are walls as there would be in a normal house, but they are all made of inorganic waste," Ms Christensen, who is also an environmental campaigner, told the BBC.A man looks out from a bedroom at Save the Beach hotel in Rome, 4 June 2010 The hotel will...

The Earth and Moon formed later than previously thought

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later – perhaps up to 150 million years after the formation of the solar system. The research results have been published in the scientific journal, Earth and Planetary Science Letters. "We have determined the ages of the Earth and the Moon using tungsten isotopes, which can reveal whether the iron cores and their stone surfaces have been mixed together during the collision”, explains Tais W. Dahl, who did...

`Banks' allow members to pay with time, not cash

ALLENTOWN, Pa. – No money? No problem! Pay with time, instead. That's what Maria Villacreses did when the economy put a hitch in her wedding plans: She used "time dollars" on everything from a wedding-day makeover to an elaborate seven-layer cake. In a modern twist on the ancient practice of barter, people like Villacreses are joining time banks to help them get the things they need or want without having to spend cash. In a time bank, members get credit for services they provide to other members, from cooking to housekeeping to car rides to home repair. For each hour of work, one time dollar is deposited into a member's account, good for services offered by other members. Scores of time banks are being started in hard-hit communities...

Blood test for cancer detection before it starts

In a major breakthrough, British researchers have developed a blood test that can detect cancer even before it develops and can be diagnosed with tests in use at present. The new test, which replicates the cancer proteins that trigger the body’s response to the disease, has been developed by the University of Nottingham’s spin-out company Oncimmune Ltd. It will help detect cancer as much as five years earlier than testing methods like mammography and CT scans. The blood test was developed from the early work of John Robertson, a world renowned breast cancer specialist and professor of surgery at Nottingham University. It is expected to change the current paradigm of diagnosis and treatment for most solid cancers such as lung, breast,...
