7 great medical myths revealed

Think we use only 10 percent of our brains? Think again

These well-worn theories are among seven “medical myths” exposed in a paper published on Friday in the British Medical Journal, which traditionally carries light-hearted features in its Christmas edition.

Two U.S. researchers took seven common beliefs and searched the archives for evidence to support them.

Despite frequent mentions in the popular press of the need to drink eight glasses of water, they found no scientific basis for the claim.

The complete lack of evidence has been recorded in a study published the American Journal of Psychology, they said.

The other six “myths” are:

• Reading in dim light ruins your eyesight

The majority of eye experts believe it is unlikely to do any permanent damage, but it may make you squint, blink more and have trouble focusing, the researchers said.

• Shaving makes hair grow back faster or coarser

It has no effect on the thickness or rate of hair regrowth, studies say. But stubble lacks the finer taper of unshaven hair, giving the impression of coarseness.

• Eating turkey makes you drowsy

It does contain an amino acid called tryptophan that is involved in sleep and mood control. But turkey has no more of the acid than chicken or minced beef. Eating lots of food and drink at Christmas are probably the real cause of sleepiness.

• We use only 10 percent of our brains

This myth arose as early as 1907 but imaging shows no area of the brain is silent or completely inactive.

• Hair and fingernails continue to grow after death

This idea may stem from ghoulish novels. The researchers said the skin dries out and retracts after death, giving the appearance of longer hair or nails.

• Mobile phones are dangerous in hospitals

Despite widespread concerns, studies have found minimal interference with medical equipment.

The research was conducted by Aaron Carroll, an assistant professor of pediatrics at the Regenstrief Institute, Indianapolis, and Rachel Vreeman, fellow in children’s health services research at Indiana University School of Medicine.

A young wife sat on a sofa on a hot humid day,

drinking iced tea and visiting with her Mother. As

they talked about life, about marriage, about the

responsibilities of life and the obligations of

adulthood , the mother clinked the ice cubes in her

glass thoughtfully and turned a clear, sober glance

upon her daughter.

'Don't forget your Sisters,' she advised, swirling

the tea leaves to the bottom of her glass. 'They'll

be more important as you get older. No matter how

much you love your husband, no matter how much you

love the children you may have, you are still going

to need Sisters. Remember to go places with them now

and then; do things with them.'

'Remember that 'Sisters' means ALL the women...

your girlfriends, your daughters, and all your other

women relatives too. 'You'll need other women. Women

always do.'

What a funny piece of advice!' the young woman

thought . Haven't I just gotten married?

Haven't I just joined the couple-world? I'm now a

married woman, for goodness sake! A grownup! Surely

my husband and the family we may start will be all I

need to make my life worthwhile!'

But she listened to her Mother. She kept contact

with her Sisters and made more women friends each

year . As the years tumbled by, one after another,

she gradually came to understand that her Mom really

knew what she was talking about. As time and nature

work their changes and their mysteries upon a woman,

Sisters are the mainstays of her life.

After more than 50 years of living in this world,

here is what I've learned:

THIS SAYS IT ALL:

Time passes.

Life happens.

Distance separates.

Children grow up.

Jobs come and go.

Love waxes and wanes.

Men don't do what they're supposed to do.

Hearts break.

Parents die.

Colleagues forget favors.

Careers end.

BUT.........

Sisters are there, no matter how much time and how

many miles are

between you. A girl friend is never farther away

than needing her can reach.

When you have to walk that lonesome valley and you

have to walk it by yourself, the women in your life

will be on the valley's rim, cheering you on,

praying for you, pulling for you, intervening on

your behalf, and waiting with open arms at the

valley's end.

Sometimes, they will even break the rules and walk

beside you...Or come in and carry you out.

Girlfriends, daughters, granddaughters,

daughters-in-law , sisters, sisters-in-law, Mothers,

Grandmothers, aunties, nieces, cousins, and extended

family , all bless our life!

The world wouldn't be the same without women, and

neither would I. When we began this adventure called

womanhood , we had no idea of the incredible joys or

sorrows that lay ahead. Nor did we know how much we

would need each other.

International Design

 

 

China's current building boom is doing more than sucking up the world's supply of steel -- it's creating a stage for some of today's boldest architecture and engineering. Take a tour of the 10 of the most intriguing examples.

 

Beijing International Airport, Beijing

Foster & Partners. Under construction, to be completed in late 2007
According to the U.S. Embassy to China, the country will be building 108 new airports between 2004 and 2009 -- including what will be the world's largest: the Beijing International Airport, designed by Foster & Partners. Set to open at the end of 2007, in time for the Beijing Olympics in 2008, the airport terminal will cover more than 1 million square meters, giving it a bigger footprint than the Pentagon.

 

 

It's designed to handle 43 million passengers a year initially and 55 million by 2015, figures that will probably push the new facility into the ranks of the top 10 busiest airports, going by the 2004 numbers from the Airports Council International. Given the scale and traffic, Foster & Partners focused on the traveler's experience, making sure that walking distances are short, for instance.

 

Shanghai World Financial Center, Shanghai

Kohn Pederson Fox Architects. Under construction, completion scheduled for 2008
Rising in the Lujiazhui financial district in Pudong, the Shanghai World Financial Center is a tower among towers. The elegant 101-story skyscraper will be (for a moment, at least) the world's tallest when completed in early 2008.

 

 

One of the biggest challenges of building tall is creating a structure that can withstand high winds. The architects devised an innovation solution to alleviate wind pressure by adding a rectangular cut-out at the building's apex. Not only does the open area help reduce the building's sway but it also will be home to the world's highest outdoor observation deck -- a 100th-floor vista that will take vertigo to new heights.

 

National Swimming Center, Beijing

PTW and Ove Arup. Under construction, completion scheduled for 2008
The striking exterior of the National Swimming Center, being constructed for the 2008 Olympic Games and nicknamed, the "Water Cube," is made from panels of a lightweight form of Teflon that transforms the building into an energy-efficient greenhouse-like environment. Solar energy will also be used to heat the swimming pools, which are designed to reuse double-filtered, backwashed pool water that's usually dumped as waste.

 

 

Excess rainwater will also be collected and stored in subterranean tanks and used to fill the pools. The complex engineering system of curvy steel frames that form the structure of the bubble-like skin are based on research into the structural properties of soap bubbles by two physicists at Dublin's Trinity College. The unique structure is designed to help the building withstand nearly any seismic disruptions.

 

Central Chinese Television CCTV, Beijing

OMA/Ole Scheeren and Rem Koolhaas. Under construction, scheduled for completion in 2008
The design of the new Central Chinese Television (CCTV) headquarters defies the popular conception of a skyscraper -- and it broke Beijing's building codes and required approval by a special review panel. The standard systems for engineering gravity and lateral loads in buildings didn't apply to the CCTV building, which is formed by two leaning towers, each bent 90 degrees at the top and bottom to form a continuous loop.

 

 

The engineer's solution is to create a structural "tube" of diagonal supports. The irregular pattern of this "diagrid" system reflects the distribution of forces across the tube's surface. Designed by Rem Koolhaas and Ole Scheeren and engineered by Ove Arup, the new CCTV tower rethinks what a skyscraper can be

 

Linked Hybrid, Beijing

Steven Holl Architects; Li Hu, lead architect. Groundbreaking on December 28, 2005, scheduled for completion in 2008
Linked Hybrid, which will house 2,500 people in 700 apartments covering 1.6 million square feet, is a model for large-scale sustainable residential architecture. The site will feature one of the world's largest geothermal cooling and heating systems, which will stabilize the temperature within the complex of eight buildings, all linked at the 20th floor by a "ring" of service establishments, like cafés and dry cleaners. A set of dual pipes pumps water from 100 meters below ground, circulating the liquid b etween the buildings' concrete floors.

The result: The water-circulation system serves as a giant radiator in the winter and cooling system in the summer. It has no boilers to supply heat, no electric air conditioners to supply cool. The apartments also feature gray-water recycling -- a process that's just starting to catch on in Beijing in much smaller buildings -- to filter waste water from kitchen sinks and wash basins back into toilets.

 

Dongtan Eco City, Dongtan

Masterplan by Arup, for the Shanghai Industrial Investment Corp. In planning stages, first phase to be completed in 2010
Developed by the Shanghai Industrial investment Corp., Dongtan Eco City, roughly the size of Manhattan, will be the world's first fully sustainable cosmopolis when completed in 2040. Like Manhattan, it's situated on an island -- the third-largest in China. Located on the Yangtze River, Dongtan is within close proximity of the bustle of Shanghai.

 

 

By the time the Shanghai Expo trade fair opens in 2010, the city's first phase should be completed, and 50,000 residents will call Dongtan home-sweet-sustainable-home. The goals to be accomplished in the next five years: systems for water purification, waste management, and renewable energy. An infrastructure of roads will connect the former agricultural land with Shanghai.

 

Olympic Stadium, Beijing

Herzog & de Meuron. Under construction, to be completed in 2008
Sports stadiums have long followed the enduring design of one of the original wonders of the world, Rome's Coliseum. Herzog & de Meuron's National Stadium in Beijing is an attempt to rethink the classic sports-arena layout for more ecologically correct times.

The Swiss architects (of Tate Modern fame) wanted to provide natural ventilation for the 91,000-seat structure -- perhaps the largest "eco-friendly" sports stadium designed to date. To achieve this, they set out to create a building that could function without a strictly enclosed shell, yet also provide constant shelter for the audience and athletes alike.

 

 

To solve these design problems, they looked to nature for inspiration. The stadium's outer grid resembles a bird's nest constructed of delicately placed branches and twigs. Each discrete space within the facility, from restrooms to restaurants, is constructed as an independent unit within the outer lattice -- making it possible to encase the entire complex with an open grid that allows for natural air circulation. The architects also incorporated a layer of translucent membrane to fill any gaps in the lacy exterior.

 

Donghai Bridge, Shanghai/Yangshan Island

China Zhongtie Major Bridge Engineering Group, Shanghai # 2 Engineering Co., Shanghai Urban Construction Group. Officially opened in December, 2005
A key phase in the development of the world's largest deep-sea port was completed when China's first cross-sea bridge -- the 20-mile, six-lane Donghai Bridge -- was officially opened in December, 2005. Stretching across the East China Sea, the graceful cable-stay structure connects Shanghai to Yangshan Island, set to become China's first free-trade port (and the world's largest container port) upon its completion in 2010.

 

 

To provide a safer driving route in the typhoons and high waves known to hit the region, Donghai Bridge is designed in an S-shape. The structure, reported by Shanghai Daily to have cost $1.2 billion, will hold its title of China's -- and one of the world's -- longest over-sea bridge for only a couple of years, though. In 2008, the nearby 22-mile Hangzhou Bay Transoceanic Bridge, which also begins (or ends, depending on your journey) in Shanghai, will earn the superlative.
