Estrogen fuels a woman’s competitiveness streak the same way testosterone does in men, scientists say.
A research revealed estrogen fuels a lust for power, with single women and those not on the Pill particularly vulnerable to the vagaries of the hormone.
Levels of estradiol – a form of estrogen – shot up in power motivated women when they won a computer game and plummeted when they lost.
The finding, by US and German researchers, mirrors the role of the sex hormone testosterone in driving feelings of dominance in men.
Inspired by a recent Cambridge University study that showed male financial traders make more money when their testosterone levels are high. Women’s hormone fluctuate in a similar way.
Power-driven women – 49 in all – were pitted against each other on a quick-fire computer game for 10 rounds.
“Following each round, they were told whether they won or lost and they could watch each other’s reaction to winning or losing,” said Stanton, an expert in the psychology of motivation.
Saliva samples taken during and after the contest showed the levels of estradiol in highly motivated women rocketed when they won and stayed high for at least 24 hours. When they lost, levels plunged.
The fluctuations were particularly noticeable in single women and those not on the Pill, the journal Hormones and Behavior reported.
Those who were not powered motivated, if they won, their estrogen went down. If they lost their estrogen went up a little bit.

Would you believe that stimulating the nerves with tiny amounts of electricity could help you lose weight? That’s what the research shows about a patients who had electrodes implanted at the junction between the esophagus and the stomach cut their calorie intake by more than 30 per cent in a month.
Patients with a body mass index of around 35 (the target for men is 20.1-25, and for women 18.7-23.8), lost an average of 14 per cent of their excess weight in up to six months.
The weight loss was achieved without any additional dieting or other therapy.
The electrodes have a blocking effect on the vagus nerve, which provides communication between the brain and the digestive system.
Research suggest the nerve is involved in the expansion of the stomach to accommodate food, the release of gastric acids, the emptying of the stomach contents and the sensation of hunger and fullness.
The therapy is based on an early treatment for ulcers,where patients had the nerves near the stomach severed.
A side effect of this treatment was that patients lost weight. But the effect was temporary as the body adapted to it and sought other ways of getting the information to the brain.
With the electrical stimulation, nerves are blocked only intermittently, and the result is that the body does not try to find alternative ways of communicating the brain.
In a trial, 31 patients were given five minutes of the nerve blocking treatment, alternating with five minutes without blocking for 12 hours a day.
Exactly how it has an effect on weight and food intake is still being investigated.

A new once-a-day weight-lose pill can help woman drop two dress sizes in six months, British scientists have said.
A survey revealed women spend 10 years of their lives dieting.
Scientists have admitted they were astonished by trials on tesofensine, which could be on the market in three years.
By targeting the part of the brain that controls appetite, it makes the user fell full soon after starting a meal and cuts the urge to snack.
Taken for six months, it is said to help achieve an average weight loss of 9.5kg – twice the amount achieved by any obesity drug now on the market.
But there is a worrying list of side-effects – mild nausea, diarrhoea, constipation and increase heart rate.
Future trials will be held to determine whether the side-effects outweigh the benefits.
Meanwhile, a study by LIPObind, a company that makes natural weight-loss supplements, polled 4000 British women and found a third started dieting aged 16 or under.
It said the typical woman will go on two diets a year, each lasting on average five weeks.
That ads up to 104 diets from age 18 to 70, a whopping total of 10 years.
One in 10 women spend 25 years or more dieting.
But while each diet sees an average drop of 2.8kg, a quarter lose nothing at all.
Thirty-nine per cent said they dieted because they were embarrassed about their looks.
The same number admitted being shy when stripping off in front of their partner.
And a shocking 25 per cent would be willing to to under the knife to get rid of extra kilos.

Do you now that our eyes actually reveal patterns in our health? This is how Iridology explains. Iridology is the technique used to analyse the structure, texture, and colour of the iris, the pigmented part of the eye. The various marks and colours that may be found on the iris are thought to reveal physical conditions, including sigris of congestion, inflammation and under- or over-activity in a specific area of the body. For example, an under-active pancreas may indicate a diabetic condition in a patient. Iridology can also uncover emotional and mental problems that may otherwise go undetected.
Iridology was developed in the 19Th century, Hungarian physician, Dr Ignaz von Peczely, devised a chart of the iris and the areas of the body it’s said to reflect.
It works by using the iris chart. At the top is the head and at the bottom is the lower abdomen and pelvic area. The right side of the body is reflected in the right eye, while the left side of the body corresponds with the left eye, Mid-lying organs and tissues, such as the brain, spine and thyroid, appear in the iris of both eyes, as do bilateral organs like the kidneys.
An iridologist looks for any changes to the iris’s ‘ideal structure’ in the form of marks or colouration’s that can be used to identify the body’s susceptibility towards certain illnesses.
I was checked with an Iridologist before and I was amazed that she found out what are my problems like having UTI and my family history of having goiter. She even told me what to watch out with my health to avoid problems like taking care of my lungs.
The eye is the window of the soul – a proverb that may ring true, according to iridologists, who examine the iris of the eye to find clues to a person’s health status.

Hair-raising cells offer bald solution. Cells grown in a laboratory may offer a solution to hair loss, preliminary trials suggest.
The technique involves taking a small amounts of the remaining hair cells, multiplying them, then injecting them into bald areas.
Six months after treatment, 11 out of 19 patients had grown new hair, UK researchers told an Italian conference.
But a UK specialist said more work would be needed so the new hair looked right.
The new method, called “follicular cell implantation” and developed by British firm Intercytex, claims to be able to provide a limitless supply of replacement hair cells.
If trials show it to be safe and effective, it could be available within five years.
Doctors take only the dermal papilla cells, which are found in the follicle and are responsible for hair growth.
They are harvested from areas on the back of the head, bathed in a specially developed chemical and placed back into bald areas of the scalp.
“It will revolutionise hair care, I think,” said Intercytex’s scientific officer Dr Paul Kemp.
“People will use this when they are starting to go bald – they’ll come and see us, we’ll take a few dermal papilla cells, grow them up in the lab, freeze most of them, and inject some.”
“They can keep coming back as the balding process continues.
“I’m convinced it will work – it’s just a question of fine tuning the technique.

Have you seen those people who suffered from facial paralysis or most known to us as face stroke? We merely called this kind of paralysis as mild kind of stroke and can be treated easily than the full body paralysis. There are facial paralysis surgeon that can help those people according to what I saw while searching online. I really find it interesting when I saw read the term that is new to me called Bell’s Palsy which is said to be a kind of disorder caused by the body response of a virus. To make this post short guys and for you to read the full details just visit http://www.facialparalysisinstitute.com/bells_palsy.php or http://www.facialparalysisinstitute.com because this is really a very informative site. I’m still reading it and I don’t have the right to copy the text and information that I got from there.

Are you familiar with this term labia surgery or did you already heard about this kind of surgery? Oh well, It’s my first time encountering this word and it really caught my attention to read it.
Two surgeons internationally renowned in Atlanta have performed labia reduction surgery and laser vaginal rejuvenation surgery in 46 states and 23 countries. Yes guys labia surgery is vaginal cosmetic surgery or vaginal rejuvenation surgery. Simply repairing hymen and Dr. Miklos / Moore are the two surgeons who had performed that. What an interesting thing right? OK just visit the internets most comprehensive web site http://www.lvratlanta.com/ for more information.

Hi Mum…sorry, Dad

A transgender man in the US has stirred up an ethical storm by revealing that he is seven months pregnant.
Thomas Beatie, a silk green printing company owner from Bent, Oregon, says he is due to give birth to a girl in July.
Beatie, who was born a woman named Tracy Lagondino and now is legally man, wrote in gay mag The Advocate he started sex reassignment 10 years ago.
But rather than have the complete sex-change surgery, he only had breast surgery and testosterone treatment and retained his “reproductive rights” meaning he still has ovaries and a uterus.
“Wanting to have a biological child is neither a male nor female desire, but a human desire, “he wrote.
With his wife, Nancy, unable to have kids after a hysterectomy 20 years ago, the couple decided two years ago that he would carry their baby and Beatie stopped taking his testosterone injections.
The couple claim they went through nine doctors in a year before buying a sperm from an anonymous donor and having a home insemination.
Doctors say the story is unusual, but possible.
“Biologically, that all sounds plausible,” said Mark Nicholas, professor of obstetrics and gynaecology at Oregon Health and Science University.
Transgender men have given birth before, according to Cedars-Sinai Medical Centre obstetrician Lisa Masterson.
But doubt has been cast on this story, with neighbours telling a local TV station they thought it was a hoax.
The Advocate has insisted Beatie’s doctor has confirmed the pregnancy.

Artificial human sperm could come to the aid of infertile men, according to a team of German scientists who have used lab-grown sperm to inseminate mice.

Artificial sperm could also make males totally redundant, permitting women to give birth without a biological male mate.

The genetic scientists at the University of Goettingen in Germany have produced 65 mouse foetuses using sperm which was grown from embryonic stem cells, according to a Deutschlandfunk radio report.

Twelve baby mice have been born using this artificial, lab-grown sperm, said Dr Wolfgang Engel, director of Human Genetics at the medical university.

However, the mortality rate is high, he told the German broadcaster.

“We started out with 65 embryos from egg cells which had been inseminated by the sperm-like cells created in our lab. Of those, 12 reached full term and were born. But seven of the newborn animals died within a period ranging from three days to five months after birth of causes which we have not been able to determine,” he said.

“So you can see that this is all still in the very early experimental stages,” he added. “If it works in the mouse, I’m sure it will also work in the human.”

A sperm cell from an embryonic stem cell would still not give an infertile man a biological tie to his child, however. It would not be any different than using donor sperm.

Dr Engel’s team has now turned to generating sperm from very early germ cells taken from the testicles. Another possibility is to try and generate viable sperm cells using stem cells in bone marrow.

Dr Engel says if sperm can be grown in the lab, it would be possible to take early germ cells from one woman, turn them into sperm cells, and use those to fertilise the egg of another woman.

But Dr Engel said his team will stop short of tests on humans in compliance with federal law in Germany which bans all genetic research using human stem cells.

He said one member of his team has gone to Newcastle, England, to conduct research on artificial human sperm.

An American company has begun selling over-the-counter DNA paternity tests.
A swab, a consent form, an envelope and a waiting period of three to five business days is all there is to settling paternity issues with the test kit, which went on sale today at some US pharmacies.
Identigene, which runs a DNA testing laboratory, said its DNA Paternity Test Collection Kit went on sale 4363 Rite Aid pharmacies throughout the United States, except New York.
The swab in the $32 kit is used to collect s saliva sample, to be mailed to the Identigene laboratory for an analysis that costs an additional $129.
It takes three to five business days to get the test results, which are delivered by mail, email, or online through a secured web service.
The paternity test kit is already a hit in California, Washington and Oregon states, where they have been selling on a trial basis since November.
According to the statement “Demand has been very strong, store sales are brisk and Identigene has been inundated with questions regarding the product’s availability,”
Test kit buyers include women who want to know the identity of the father of their child – or unborn child – as well as people looking for their parents.
Sold with prescription, the paternity kits are not allowed as evidence in court, where more precise and costly DNA tests are required.
