Ended
the sharp edge of the Tas sand in a park "Thumamah wild" the lives of
five girls on Thursday evening, while sent six others to hospital
Chemissi and King Faisal Specialist Hospital, and the sharp edge and the
so-called fans hobby Alttaiss "the story of the sword" surprised the
girls who went out in the modern model for a car, "Toyota Land Cruiser" Wild Alttaiss engaged in a private farm owned by the family of one of them. Girls
were going out their heads and bodies from the windows of the
vehicle, I was surprised when the leader of the car marked by the
sharp sand to turn the car in the incident.And considered the security authorities, which began a traffic accident that is purely and there is no suspicion of criminal.The
incident, which occurred in a park road north east of the capital
Riyadh (Thumamah) in the late evening of yesterday, killing five girls
and wounding six others are still receiving medical care in a hospital
Chemissi (central Riyadh), according to a medical source saidThe
source said that the infected have been subjected to serious injuries
ranging from multiple fractures and bruises in the important parts of
their bodies, making it necessary to survival under intensive care.It
was close to the area of the incident, have informed the competent
authorities thereof, where teams went Red Crescent, security patrols and
the passage of Riyadh to the location of the incident.The
incident, which is still shrouded in some mystery classified as a
traffic accident and there is no purely any suspicion of criminal.Denied
the assistant press secretary for the Riyadh Region Police Major
Fawaz Maiman in a comment on the incident and there is no suspicion of
criminal behind the incident or the existence of harassment
contributed to the incident, pointing out that the car was led by a
woman in the middle of the second decade of life, along with ten of
her colleagues, and crashed into a barrier of dirt in Park, particularly in the area Thumamah northeast of Riyadh.For
his part, said the supervisor of the incident from the Red Crescent
Mazin Al-Ghamdi said that girls were not are leading to a paved road,
but on a hill of sand, pointing out that the report of the incident
have not yet been released. He stated that this incident is only for girls during the holiday period.The girls ranged in age between 18 and 25 years in the tower will, according to Al-Watan newspaper.

Medical drama House to end, says Hugh Laurie

US medical drama House is to finish its eight-year run at the end of this series in April, it has been announced.
The show's producers, including British star Hugh Laurie,
said it was a "painful" decision but that the time had come to bring it
to a close.Laurie plays Gregory House, the brilliant but troubled doctor with an unconventional bedside manner.
It has won nearly 40 awards since it began, including two Emmys and two Golden Globes.
House has won the favourite TV drama prize at the People's Choice Awards for the past four years.
The show also stars Omar Epps, Robert Sean Leonard and Charlyne Yi.
In a statement, 52-year-old Laurie and fellow producers David Shore and Katie Jacobs said: "We have always imagined House as an enigmatic creature; he should never be the last one to leave the party.
"How much better to disappear before the music stops, while there is still some promise and mystique in the air."
House is shown on Sky1 in the UK.
Men can inherit a form of heart disease from father via Y chromosome

Men
can inherit heart disease from their father say scientists who have
tracked the condition to the Y chromosome that dads pass to sons.
By studying the DNA of over 3,000 men they found a particular
version of the sex chromosome increases the risk of coronary artery
disease by 50%.As many as one in five British men carry this version of Y.
And the risk it confers is in addition to other heart risk factors like cholesterol, The Lancet reports.
Experts already know that men develop heart disease a decade earlier than women, on average. By the age of 40, the lifetime risk of heart disease is one in two for men and one in three for women.
Lifestyle factors like smoking and blood pressure are important contributors. This latest work suggests the male Y chromosome can also play a role in coronary artery disease - a common form of heart disease that kills thousands each year in the UK.

Dr Maciej Tomaszewski Lead researcherDoctors usually associated the Y chromosome with maleness and fertility but this shows it is also implicated in heart disease”
Dr Maciej Tomaszewski, from the
University of Leicester, and colleagues studied 3,233 biologically
unrelated British men who were already enrolled in other medical studies
investigating heart disease risk.
When they carried out genetic tests on the men they found
that 90% possessed one of two common versions of Y chromosome - named
haplogroup I and haplogroup R1b1b2.And the risk of coronary artery disease among the men carrying the haplogroup I version was 50% higher than in other men.
The scientists say they now need to pinpoint precisely which genes on the Y chromosome are responsible.
But they believe they already know how they exert their effect - by upsetting a man's immune system.
Dr Maciej Tomaszewski, a clinical senior lecturer at the University's Department of Cardiovascular Sciences, said: "We are very excited about these findings as they put the Y chromosome on the map of genetic susceptibility to coronary artery disease.
"Doctors usually associated the Y chromosome with maleness and fertility but this shows it is also implicated in heart disease."
He said, ultimately, the discovery could lead to new ways to treat and prevent heart disease in men, as well as a genetic test to spot those greatest risk.
In the meantime, he said men should focus on risk factors that they already have the power to modify themselves, such as getting enough exercise and eating a healthy diet to keep their blood pressure and cholesterol down.
Dr Hélène Wilson of the British Heart Foundation, which part-funded the work, said: "Coronary heart disease is the cause of heart attacks, which claim the lives of around 50,000 UK men every year.
"Lifestyle choices such as poor diet and smoking are major causes, but inherited factors carried in DNA are also part of the picture. The next step is to identify specifically which genes are responsible and how they might increase heart attack risk."
Zebra stripes evolved to keep biting flies at bay

The team placed the sticky model horses in afly-infested field
Why zebras evolved their characteristic black-and-white stripes has been the subject of decades of debate among scientists.
Now researchers from Hungary and Sweden claim to have solved the mystery. The stripes, they say, came about to keep away blood-sucking flies.
They report in the Journal of Experimental Biology that this pattern of narrow stripes makes zebras "unattractive" to the flies.
They key to this effect is in how the striped patterns reflect light.
- There are many theories about why zebras are striped
- Scientists have proposed that the mass of stripes in a large herd confuses predators
- Others have shown that stripes may help the animals regulate their temperature, and that zebras recognise other individuals by their stripes
- Studies of zebra embryos show that, early in development, they are black and they develop their white stripes later
- Horses, donkeys and zebras videos, news and facts
"We started off studying horses
with black, brown or white coats," explained Susanne Akesson from Lund
University, a member of the international research team that carried out
the study.
"We found that in the black and brown horses, we get
horizontally polarised light." This effect made the dark-coloured horses
very attractive to flies. It means that the light that bounces off the horse's dark coat - and travels in waves to the eyes of a hungry fly - moves along a horizontal plane, like a snake slithering along with its body flat to the floor.
Dr Akesson and her colleagues found that horseflies, or tabanids, were very attracted by these "flat" waves of light.
"From a white coat, you get unpolarised light [reflected]," she explained. Unpolarised light waves travel along any and every plane, and are much less attractive to flies. As a result, white-coated horses are much less troubled by horseflies than their dark-coloured relatives.
Having discovered the flies' preference for dark coats, the team then became interested in zebras. They wanted to know what kind of light would bounce off the striped body of a zebra, and how this would affect the biting flies that are a horse's most irritating enemy.
"We created an experimental set-up where we painted the different patterns onto boards," Dr Akesson told BBC Nature.
She and her colleagues placed a blackboard, a whiteboard, and several boards with stripes of varying widths into one of the fields of a horse farm in rural Hungary.
"We put insect glue on the boards and counted the number of flies that each one attracted," she explained.
The striped board that was the closest match to the actual pattern of a zebra's coat attracted by far the fewest flies, "even less than the white boards that were reflecting unpolarised light," Dr Akesson said.
"That was a surprise because, in a striped pattern, you still have these dark areas that are reflecting horizontally polarised light.
"But the narrower (and more zebra-like) the stripes, the less attractive they were to the flies."
To test horseflies' reaction to a more realistic 3-D target, the team put four life-size "sticky horse models " into the field - one brown, one black, one white and one black-and-white striped, like a zebra.
The researchers collected the trapped flies every two days, and found that the zebra-striped horse model attracted the fewest.
Prof Matthew Cobb, an evolutionary biologist from the University of Manchester pointed out that the experiment was "rigorous and fascinating" but did not exclude the other hypotheses about the origin of zebras' stripes.
"Above all, for this explanation to be true, the authors would have to show that tabanid fly bites are a major selection pressure on zebras, but not on horses and donkeys found elsewhere in the world... none of which are stripy," he told BBC Nature.
"[They] recognise this in their study, and my hunch is that there is not a single explanation and that many factors are involved in the zebra's stripes.
