Lipz to Hipz
As every dieter knows, a moment on the lips could spell a lifetime on the hips. But now the adage has been turned on its head, with the creation of a lip gloss that claims to help women lose weight.
Sold under the slogan "Always on the lips. Never on the hips", Fuze Slenderize gloss is said to be oozing with ingredients that curb the appetite.If that weren't enough, the "guilt-free lip gloss" also claims to speed up the metabolism, while boosting energy levels. One of the key ingredients is SuperCitrimax, a plant extract said to keep hunger pangs at bay and stop the body turning carbohydrates into fat. Katie Holmes is rumoured to be a fan of drinks with a similar ingredient. Other contents include chromium, a mineral said to boost metabolism, and L-carnitine, an energy-giving amino acid. Similar ingredients are found in Fuze diet drinks, a range of low-calorie fruit juices reputed to be a favourite of actresses Katie Holmes and Jessica Simpson. Costing £9.50 a tube, the brightly-coloured gloss is made by Californian make-up company Too Faced and is available in three flavors.
A spokesman for Too Faced said: "Application of this long-lasting, high-shine formula will actually help suppress one's appetite for food without sacrificing delicious glamour. "With a single swipe of the tube, Fuze Slenderize provides a pretty, plump pout with an added bonus of healthy, energy-boosting, appetite curbing ingredients.
"One delicious dab on the lips will give you a taste of what all the Hollywood starlets are losing it over."
Available by mail order from cosmetics company Sephora, the gloss comes in a trio of flavours - blueberry and raspberry, strawberry and melon and dragon fruit and lime. However, diet experts cautioned there is no quick-fix when it comes to losing weight. Tam Fry, of the National Obesity Forum, said: "People will buy this and it will do nothing for them unless they have already taken steps to lose weight. "There is only one way to lose weight in the long-term and that is by sensible eating, sensible exercise and making sure you know what you are eating and it is not full of fat, sugar and salt.
"People should pay more attention to what goes into their mouth than what goes on their lips."
Too Faced is not the first company to produce a lip gloss with healthy properties. Other glosses already on the market claim to use the scent of vanilla to lift mood and the smells of lemon and geranium to curb smokers' cravings for nicotine.

Cheeseburger in a Can
This is a cheeseburger. In a can. It's a cheeseburger in a can.
I honestly can't figure out how I feel about this: is it the greatest achievement of mankind thus far, or is it an abomination of foodstuffs that deserves to be hucked back into the gaping maw of whatever food processing plant it was spewed from? I just don't know what to think anymore. Would you eat a cheeseburger in a can? Keep in mind that it'll look nowhere near as delicious as the example above when you pull it out of the can.

Researchers in Maryland unleash synthetic DNA
Researchers at the J. Craig Venter Institute have created the largest man-made DNA structure to date, putting them one step closer to producing a completely synthetic organism, according to the institute.
The work, published online by Dan Gibson, Ph.D. in the journal Science, raises hopes for benefits like new drugs and pollution scarfing micro-organisms while spooking some with visions of biological warfare and patent wielding corporations controlling all future forms of synthetic life.
The researchers chemically created DNA fragments in the lab then used homologous recombination (a process that cells use to repair damage to their chromosomes) in the yeast Saccharomyces cerevisiae to rapidly build the entire bacterial chromosome from large sub-assemblies, according to the press release. "This extraordinary accomplishment is a technological marvel that was only made possible because of the unique and accomplished JCVI team," said president and founder J. Craig Venter.
Venter dismisses concerns that what JCVI is really creating is the "microbesoft" of synthetic life. His team has long been concerned with the societal issues surrounding its work and has undergone"significant ethical review" by experts who founds no reason why work should cease "as long as the scientists involved continued to engage public discussion," according to the JCVI Web site.
Critics remain unimpressed. "Venter is claiming bragging rights to the world's longest length of synthetic DNA, but size isn't everything. The important question is not 'how long?' but 'how wise?'" said Jim Thomas in a bio-watchdog article castigating Venter.
"While synthetic biology is speeding ahead in the lab and in the marketplace, societal debate and regulatory oversight is stalled and there has been no meaningful or inclusive discussion on how to govern synthetic biology in a safe and just way. In the absence of democratic oversight profiteering industrialists are tinkering with the building blocks of life for their own private gain."
Next step would be to insert the synthetic DNA into living cells and hope it becomes the world's first artificially created, self-replicating organism.

Finnish patient gets new jaw from own stem cells
Scientists in Finland said they had replaced a 65-year-old patient's upper jaw with a bone transplant cultivated from stem cells isolated from his own fatty tissue and grown inside his abdomen. Researchers said on Friday the breakthrough opened up new ways to treat severe tissue damage and made the prospect of custom-made living spares parts for humans a step closer to reality.
"There have been a couple of similar-sounding procedures before, but these didn't use the patient's own stem cells that were first cultured and expanded in laboratory and differentiated into bone tissue," said Riitta Suuronen of the Regea Institute of Regenerative Medicine, part of the University of Tampere.
She told a news conference the patient was recovering more quickly than he would have if he had received a bone graft from his leg. "From the outside nobody would be able to tell he has been through such a procedure," she said. She added, the team used no materials from animals -- preventing the risk of transmitting viruses than can be hidden in an animal's DNA, and followed European Union guidelines.
Stem cells are the body's master cells and they can be found throughout the blood and tissues. Researchers have recently found that fat contains stem cells which can be directed to form a variety of different tissues. Using a patient's own stem cells provides a tailor-made transplant that the body should not reject. Suuronen and her colleagues isolated stem cells from the patient's fat and grew them for two weeks in a specially formulated nutritious soup that included the patient's own blood serum. In this case they identified and pulled out cells called mesenchymal stem cells or immature cells than can give rise to bone, muscle or blood vessels. When they had enough cells to work with, they attached them to a scaffold made out of a calcium phosphate biomaterial and then put it inside the patient's abdomen to grow for nine months. The cells turned into a variety of tissues and even produced blood vessels, the researchers said. The block was later transplanted into the patient's head and connected to the skull bone using screws and microsurgery to connect arteries and veins to the vessels of the neck.
The patient's upper jaw had previously been removed due to a benign tumor and he was unable to eat or speak without the use of a removable prosthesis. Suuronen said her team had submitted a report on the procedure to a medical journal to be reviewed.

Work Out and Drink Up
This article by Sanjay Gupta in this weeks Time magazine was provocative & interesting. Thought our blogeurs would appreciate a bit of tippling-news.
If you want to live a long and healthy life, you're probably trying to eat right, exercise regularly and get enough sleep. Good steps. Now how about adding a little alcohol to your regimen?
That's right. It is well documented that tossing a few drinks back in a week (and that means a few: up to one a day for women, up to two for men) has potential heart benefits. But researchers in Denmark decided to look further. Could drinking alcohol have a benefit similar to that of exercise?
"If you don't want to exercise too much," asks Dr. Morten Gronbaek, epidemiologist with Denmark's National Institute of Public Health, "can you trade it for one to two drinks per day and be fine?" A study Gronbaek and colleagues just published in the European Heart Journal suggests the answer just may be yes. That finding, not surprisingly, has proved to be a crowd-pleaser.
There are a number of reasons a drink can be such a tonic. First, alcohol and exercise affect your heart health in similar ways. "They help increase good cholesterol, or HDL [high-density lipoproteins], and clean the circulatory system's pipes," says Dr. Arthur Klatsky, a cardiologist and researcher at Kaiser Permanente Northern California. "HDL helps remove fatty deposits, created by bad cholesterol, or LDL [low-density lipoproteins], from blood-vessel walls. The higher the HDL, the less likely vascular disease becomes. The lower the HDL, the more likely."
Gronbaek and his team surveyed 12,000 people over a 20-year period. They found that exercise and drinking alcohol each had an independent beneficial effect on the heart and a compounded effect when practiced together. The investigators got even greater insight when they separated the study participants into four categories.
People who don't drink at all and don't exercise had the highest risk of heart disease. People who drink moderately and exercise had a 50% lower risk. Teetotaling exercisers had a 30% decreased risk, as did moderately drinking couch potatoes. "There's an additional protective effect to doing both," says Gronbaek. "That's the new finding."
This study is part of a growing body of work that makes a medical virtue out of what was once seen as a vice. There is evidence that alcohol in combination with caffeine can limit the damage to your brain after a stroke, even though it may not lower your risk of having a stroke in the first place. Other possible benefits include lowering your risk of diabetes, improving insulin sensitivity in postmenopausal women and decreasing dementia rates in older adults who had been consuming one to six drinks per week.
Before you rush off to hit the bar after your workout, keep in mind that your age matters. Alcohol may do you no coronary good until you reach the age at which heart disease becomes an appreciable risk. "You wouldn't advise everyone to drink," says Gronbaek. "You shouldn't even think about doing it until age 45 or 50. There's absolutely no proof of a preventative and protective effect before age 45." Also, younger women who have a higher risk of breast cancer and anyone who has a family history of alcoholism should pass on the pint and order a soda.
And remember, moderation is everything. Gronbaek's study, like most, stuck to the one-drink-a-day standard for women and up to two a day for men. It did not distinguish between type (wine vs. beer) or size (pint vs. shot). But here common sense must rule. A 10-oz. martini is a lot more than a 6-oz. serving of wine, even if they each fit in one glass. And it goes without saying that you should never drink your weekly allotment all at once!
