Comment: Never try to be happy with respect to something else. There is no guarantee that you will be able to control others. So try to make yourself frame of reference if you really want to be happy:
A new study by researchers at SUNY Downstate Medical Center in the US suggests that excess worrying could be a sign of intelligence.
Scientists found that high intelligence and worry both correlate with brain activity measured by the depletion of the nutrient choline in the subcortical white matter of the brain. According to the researchers, this suggests that intelligence may have co-evolved with worry in humans.
“While excessive worry is generally seen as a negative trait and high intelligence as a positive one, worry may cause our species to avoid dangerous situations, regardless of how remote a possibility they may be,” said Jeremy Coplan, MD, professor of psychiatry at SUNY Downstate.

International Women’s Day has been marked across the globe with political protest as well as celebration and solemn observation.
In Britain, Karren Brady, vice-chairman of West Ham United and Alex Wek, rights campaigner and model, whose family fled South Sudan following the civil war, joined Nick Clegg in opening the London Stock Exchange.
“It is despicable that in the 21st century so many medieval practices and attitudes remain. And it is appalling that time and again, this is shoved under the carpet. People turn a blind eye and a culture of shame and secrecy is perpetuated. Read the rest of this entry »
In what could be a major breakthrough for fertility treatment, unlimited egg supply for women may be a step closer following new stem cell research.
The study, published in the journal Nature Medicine, challenges the long-held belief that women are born with a finite supply of eggs that will be exhausted by menopause.
Scientists isolated stem cells in the ovaries of reproductive age women and found they can produce immature eggs (oocytes) in laboratory conditions – and further tests on mice revealed the eggs could be fertilised.
The study is not the first to dispute the notion that a woman’s egg supply is gradually depleted, running out by middle age.
Lead researcher Dr Jonathan Tilly, from Massachusetts General Hospital, first questioned this theory in 2004 in a study that revealed mice have some egg-producing stem cells.
Dr Tilly said: “The primary objective of the current study was to prove that oocyte-producing stem cells do in fact exist in the ovaries of women during reproductive life, which we feel this study demonstrates very clearly.”
Researchers found the stem cells, which go on to produce oocytes, by searching for a protein that is unique to the surface of the stem cells.
Oocytes are immature female sex cells that mature to give rise to a fully mature egg cell.
The researchers grafted human ovarian tissue around the stem cells inside mice and found they “spontaneously generated” egg cells that looked and acted like oocytes. Read the rest of this entry »
British scientists have successfully ‘grown’ the three main types of cells that make up the walls of a blood vessel – a breakthrough that could revolutionise treatment for conditions such as heart disease and strokes.
Researchers from the University of Cambridge, funded by the Wellcome Trust, successfully created blood vessels in the laboratory following a four-year study using patients’ own skin cells to manufacture different types of vascular smooth muscle cells.
Scientists began by studying pluripotent stem cells. These are early biological cells that can transform into other cell types and renew themselves to produce more stem cells.
They discovered methods of turning the stem cells into various types of vascular smooth muscle cells, which help form blood vessels after being injected into mice. Read the rest of this entry »
Blasting a man’s testicles with sound waves could cut his sperm production and may be used in the future as a male contraceptive treatment, a new study has found.
Scientists at the University of North Carolina tested doses of ultrasound waves on rats and found they “significantly reduced” the number of sperm-producing cells and sperm levels.
The equivalent outcome would result in reversible infertility in humans but far more tests are required before it could be made available as a male contraceptive treatment.
Study leader Dr James Tsuruta, from the University said: “Unlike humans, rats remain fertile even with extremely low sperm counts. Read the rest of this entry »
A British woman with two vaginas has been offered $1m to appear in a porn film.
The offer was made to Hazel Jones by Vivid Entertainment boss Steve Hirsch, who wrote to her praising her as an “extraordinary woman”.
The letter, seen by TMZ, added: “I would like to make you an offer to star in an upcoming Vivid production. We would pay you up to $1m for your services.”
Embarrassing Bodies health expert Dr Dawn Harper explained on the show that Hazel’s condition occurred because the uterus tube septum failed to break down when Miss Jones was a baby, meaning two uteruses formed instead of one.
Uterus didelphys, more commonly known as ‘double uterus’ happens when a woman’s uterus forms differently and goes on to develop into two uteruses (wombs). While the condition itself is not uncommon, having two separate vaginas is extremely rare.
”The two tubes have made two separate uteruses and two vaginas and two cervixes. And although it’s relatively common to have a septum within the uterus, to actually have two separate uteruses is much rarer – one in a million,” explained Dr Harper.
MIss Jones first discovered something was wrong when she reached puberty and started her periods at 14. Read the rest of this entry »

The study, published in the Nature Biotechnology, found that their technique was 90% effective during tests and would be suitable for producing blood vessels on a wider scale. This means the so-called ‘test tube’ treatment could be used for kidney dialysis and injury repair. Read the rest of this entry »
New warnings have emerged amid the global PIP breast implant scare as reports reveal the same contaminated gel was used in male chest and testicle implants.
It has also come to light that thousands of British women are potentially at risk from faulty breast implants produced by PIP but sold under the name Rofil M-implants.
After speaking to a number of former PIP employees, the publication said: “Following an investigation, it has emerged that PIP also sold chest and testicle implants for men.
“Ex-employees of the firm Poly Implants Prothese are thought to have made these male implants from the same silicone gel used in female breast implants.
“No information is available on how many were made but we understand they were all sold for export abroad.”
Eva Ekvall, the former Miss Venezuela, has died of breast cancer aged just 28 after a two year battle with the disease.
Miss Evkall was scouted as a teenager and later crowned the winner of the Miss Universe pageant at the age of 17. She went on to become a news anchor, author and cancer charity advocate.
The young model and mother of one was diagnosed with advanced breast cancer in February 2010 after discovering a lump on her breast that she thought was due to her pregnancy. Eva underwent countless rounds of chemotherapy, radiation and had a mastectomy.
During her battle with the disease, Eva wrote a book, Fuera de Foco (‘Out of Focus’), about her ordeal which featured pictures of her during her treatment.
“The pictures were very shocking because nobody had ever seen me that way. Nobody had seen me bald, without make-up,” Ekvall said of the book.
“In the beginning I wasn’t sure if I looked good or not. Then I realised that wasn’t the point. I wasn’t supposed to look good, I had cancer.”
Eva’s book was credited with a rise of Venezuelan women having breast examinations and she later became the advocate of cancer awareness charity group, SenosAyuda.
The former beauty queen passed away on Saturday 17 December in a Texas hospital with her family by her side.
Office workers take note, sitting down for long periods of time can increase your risk of developing breast and colon cancer, according to a series of intensive medical studies.
The study results, presented at the American Institute of Cancer Research annual conference, showed a strong link between inactivity and unregulated cancer cell growth. Scientists believe that the findings are so significant, they could be linked to the cause of 92,000 cancer cases recorded each year.
In light of these study results, health experts are urging people to get off the sofa or office chair and become more active, by encouraging them to do two minutes of exercise for every hour they sit down per day.
The studies presented at the medical conference focused on breast and colon cancer. Researchers from Alberta Health Services Cancer Care in Canada found a profound link between active post-menopausal women and the decrease in cancer risks. Women who took a brisk walk each day reduced the development of key biological indicators in the body that trigger cancer risks. These include sex hormone levels, insulin resistance and body fat.
