A NASA rocket explodes at launch

Antares rocket exploded during takeoff. American rocket private company Orbital Sciences Corporation for NASA carrying Cygnus capsule supply for the International Space Station.

"The explosion occurred shortly after launch" on the Wallops spaceport on the coast of Virginia, reports a television commentator NASA. Cygnus was to deliver 2.2 tons of supplies and equipment for scientific experiments.

The Russian space agency said it was ready to supply emergency the International Space Station if he so requests.

Astronauts are currently aboard the International Space Station have enough food to take four to six months, NASA reassured. The six astronauts attended the launch missed by images broadcast by NASA and "they were disappointed, but they know they have plenty of resources on board," said the program director of the International Space Station, Mike Suffredini.

The causes of the accident are as yet unknown. There was no one on board.

For the CEO of Orbital Sciences, Frank Culbertson, "it was too early to know all the details" of the accident. He announced that an investigation would be conducted "to determine the causes of this failure and the steps to take to prevent it from happening again," said he added.

The damage appears to be limited to the ground at the shooting, according to NASA officials. Nothing but the rocket ship and loading are estimated at $ 200 million, said Frank Culbertson.

Earlier in a brief statement on its website, NASA indicated "a malfunction occurred shortly after takeoff."

For its part, Orbital had reported in a message on Twitter, as "an anomaly in the launcher" without giving further details.

Orbital says it was the first night launch for the Antares rocket and third supply mission to the eight planned under a contract of $ 1.9 billion with NASA.

Since shelved its space shuttles, the US space agency (NASA) relies on private companies like Orbital or SpaceX to resupply the ISS or to send astronauts at a lower cost. This is the first accident since NASA has given its resupply missions to the International Space Station to private operators.

What is vitamin D ? How much do we need to be healthy?

Vitamin D

Vitamin D or vitamin antirachitic calciferol or a vitamin is liposoluble ie soluble in fats. Its uniqueness lies in the fact that its main source is made ​​by the body itself.
There are several variations of vitamin D but the forms that interest us the most are:
- vitamin D2 or ergocalciferol , which is of plant origin . It is found in most foods.
- vitamin D3 or cholecalciferol , which is synthesized in the skin by the action of ultraviolet on cholesterol. Vitamin D3 is also present in animal foods such as fish oils.

Background of Vitamin D

- 1865 : physician Armand Trousseau recommends in its manual of clinical medicine the cod liver oil consumption because it has a antirachitic factor. Trousseau is also one of the first, after Russian Sniadecki, observing that exposure to sun protect children rickets.
- 1890 : English physician Palm, after an epidemiological study concluded that the only common denominator to explain the Rickets is a lack of exposure to sunlight.
- 1922 : McCollum discovers that cod liver oil retains its properties even antirachitic after destroying every vitamin A. There is therefore a second soluble factor which he called "vitamin dépositrice calcium. "
- 1924 : Dr. Harry Steenbock and Dr. Hess show that ultraviolet radiation can induce antirachitic factor in food and animals.
- End of the 20s : it is clear that rickets can be prevented and cured by exposure to direct sunlight, ultraviolet radiation, for consumption of irradiated food or cod liver oil.
- 1932 : the crystalline vitamin D2 were isolated pure.
- 1936 : crystals are pure vitamin D3 isolated from liver oil tuna.
- 1952 : Dr. Woodward made ​​the first synhtèse Vitamin D3 which earned him the Nobel Prize in Chemistry in 1965.
- 1964 : Norman detects the existence of three metabolites of vitamin D. In 1971, he established the structure of calcitriol.
- Since 1980 , receptor derivatives of vitamin D were found in the cells of many organs.

The role of vitamin D

Vitamin D plays two key roles. Firstly, it ensures optimal bone mineralization, during growth, but also throughout the life of their renewal.

Moreover, it modulates intestinal calcium absorption contributes to the stability and rate of calcium in the blood and tissues.
But that's not the only benefit of vitamin D for the body. Indeed, this vitamin is the subject of many experiments since the 90s, some researchers have high hopes on it to prevent many diseases.

It seems to be a link between vitamin D levels and the development of cancers. Indeed, some studies point to a greater risk of being hit by one of these diseases when vitamin D levels in the body are too low. In addition, people who already have potentially have a greater chance of survival with higher levels of vitamin D.

The link between lack of vitamin D and depression is still unclear to researchers but they generally consider this vitamin as a neurosteroid and agree on the likely importance in the brain. Vitamin D may, for example, facilitate the production of noradrenaline, dopamine and serotonin. Deficiency could thus lead to depressive disorders in those affected.

Cognitive disorders
As with depression, vitamin D deficiency may increase the risk of developing Parkinson's disease. Indeed, this vitamin has a protective effect on neurons and prevent that they be destroyed.

Falls and Fractures
The problem is especially common among the elderly. The bones become brittle and fractures are more common. However, vitamin D supplementation could reduce the risk of fractures due to the effect of this vitamin on the binding of calcium. But it is also true for falls because the elderly with vitamin D levels too low, were also more likely to fall. This is due to loss of balance and muscle weakness possibly caused by a lack of vitamin D.

The vitamin D in the body

- Vitamin D from the diet is absorbed with fats in the small intestine. It then joins the general circulation.
- Vitamin D formed by irradiation of the skin pass directly into the bloodstream.
- Vitamin D is mainly stored in the blood, muscle, adipose tissue, liver, kidney .
- It can then be dispatched to the intestines, bones, kidneys, muscles, the parathyroid glands .
- Vitamin D and its derivatives are eliminated by the fecal bile .

Physical and chemical properties

- heat-sensitive
- sensitive to light
- sensitive to O2
- sensitive to acid

Vitamin D needs

The needs are difficult to evaluate because they vary with the degree of sun exposure and the degree of skin pigmentation . They are theoretically zero if the body exposure to sunlight is sufficient.

A vitamin D is necessary in countries where sunlight is weak, especially in children during the first two or three years of life.


Most of the vitamin D is synthesized in the skin due to exposure to sunlight . One sees that with a minimum of exposure (15 to 30 minutes a day) the bulk of the vitamin D - 50 90% -. Skin is produced by the rest of the vitamin D is provided by the feed , primarily by fish oils, fish, butter, cereals, eggs, livers of animals and also a little milk.


Vitamin D has a key role in calcium metabolism : - it facilitates the intestinal absorption of calcium and phosphorus - it helps the binding of calcium to the bones ie their growth, but also for their renewal its renal excretion . - it acts as a hormone and hypercalcémiante will enter into relations with other hormones on calcium and phosphate metabolism.

Vitamin D deficiency

- In adults, vitamin D deficiency may result in osteomalacia (demineralization with osteopathy ostéoïdose by hypophosphocalcie)
- In children and adolescents, the rickets (due to defective bone mineralization of growing organism ostéochondrodystrophie fast and usually secondary to vitamin D2)
- Other consequences of vitamin D deficiency: osteoporosis , increased infections

Malala shared the Nobel Peace Prize with Indian Kailash Satyarthi

The Nobel Peace Prize was awarded on Friday to the Pakistani teenager Malala, a survivor of the bullets of the Taliban, and the Indian Kailash Satyarthi, a price that both winners say they want to use to defuse tensions their respective states.
Malala Youzafsaï Nobel Prize for peace,

Malala Yousafzai announced that it had agreed with Mr. Satyarthi invited to the Nobel ceremony in Oslo on December 10 heads of government of the two countries, nuclear armed rivals who exchanged fatal shootings in the area this week disputed Kashmir.

"We want India and Pakistan have good relations," she told the press hastened in his high school in Birmingham, the English city where she lives today.

After the exchange of fire and bombing, officials said, killing 17 civilians along the India-Pakistan border, India Thursday threatened his neighbor with a military escalation in the region.

Malala said she was "proud to be the first Pakistani and the first woman" to receive the Nobel Peace Prize was awarded jointly with Mr. Satyarthi for their fight against the exploitation of children and for the schooling.

By far the youngest winner in the history of Nobel top of its 17 years, the global icon of daughters was in chemistry class when the choice of the Norwegian Nobel Committee was received but she said she wanted to attend the rest of the course before commenting on its price.

"This award is for all children without a voice, and that must be heard," she has said

Less known to the public and significantly older (60 years), Kailash Satyathi, a trained engineer, is reaching children and women reduced to the status of slaves in the Indian factories where they work in horrific conditions.

"This will help increase the visibility of the cause of children who are the most neglected," said he responded in a telephone interview with the Nobel Foundation.- Pencils 'best weapons' -

"Pride of Pakistan," according to Prime Minister Nawaz Sharif, Malala is devoted to the day after a dismal birthday. On 9 October 2012, the Pakistani Taliban had intercepted his school bus and he had shot himself in the head, accusing him of undermining Islam.

The girl, who has campaigned for the age of 11 years, refused to be intimidated and continued to fight for education and tolerance.

"Let us lead the fight against illiteracy, poverty and terrorism, our books and pencils are our best weapons," she said of her firm voice last year in a highly applauded the speech UN.

According to the UN, 57 million children of school age in primary school are not in school worldwide, 52% of girls.

"With courage and determination, Malala reveals what terrorists fear most: a girl holding a book," said the secretary general of the UN, Ban Ki-moon. "The real winners of the day, it is the children of the world."
Kailash Satyarthi

The choice of the Nobel committee is especially significant in light of the April 14 kidnapping in Nigeria of 276 high school students by the Islamist movement Boko Haram (meaning "Western education is a sin"). The incident shocked the world and sparked the vast mobilization movement "Bring back our girls" ("Bring our daughters").

Kailash Satyarthi, who will share the 8 million Swedish kronor (about 873,000 euros) Nobel with Malala, participated in the creation of several defensive moves from childhood and schooling.

Bachpan Bachao Andolan organization ("Movement to Save the Children") claims to have released nearly 80,000 child workers. But according to estimates cited by the Nobel committee, the planet still has some 168 million of them.

French President Francois Hollande praised the "outstanding commitment" of the two winners and German Chancellor Angela Merkel spoke of "a good day for the world's children."

All About Ebola Virus

Since the beginning of the epidemic in 2013, approximately 50% of patients died , or 4,000 deaths according to the World Health Organization to 10 October 2014 Since 1976, depending on the strain, the morbidity rate has fluctuated between 25% and 90% . A diagnosis made ​​at the onset of symptoms improves the chances of patients , although there is no effective treatment today. In hospitals, patients are placed in isolation. The management of possible cardiac arrest or constant rehydration makes them more likely to survive.

Ebola Virus

Ebola: which countries at risk?

For now, it is the West Africa suffers mainly from the epidemic since 2013 The Liberia experienced more than 2,200 deaths, nearly three times more than its neighbor, Sierra Leone . The Guinea has also seen more than 700 deaths. Other African countries have also been affected (DRC, Nigeria) including Senegal, where the only reported case to survive. Five Americans, two Spaniards and a French nurse were infected in Africa. The latter dealt with France , is now healed. To date, the Ministry of Foreign Affairs has not established restriction of movement to the most affected countries , but recommends the greatest vigilance.

What is the origin of the Ebola virus?

In 1976 a young Belgian doctor, Peter Piot, examines the blood of a nun. The woman died of a mysterious disease in Zaire, now the Democratic Republic of Congo. The sample was sent to him by another Belgian doctor, who operates in the remote community of Yambuku along the Ebola River. Fever, bleeding: 300 people die in a few weeks in the area. Dr. Piot identifies who is responsible: a then unknown virus. Later, we discover that it was the bats that act as a reservoir for the disease, but that it can be transmitted to primates, pigs or humans. The current outbreak has been reported for the first time in 2013.

What are the symptoms of the disease?

Between HIV infection and the onset of symptoms, it may take 2 to 21 days . The person is then not contagious. Then the patient has a fever (at least 38.6 ° C) and severe fatigue. The muscle aches and headaches or sore throats are soon completed in a second phase, abdominal pain and persistent hiccups. About 3 days later, the patient is taken vomiting, diarrhea . In half the cases, it is prone to bleeding: gums, eyes, nose, stool ... Death can occur on average between the sixth and sixteenth day after the onset of symptoms.

How do you get Ebola?

Not so easily. The virus is spread by direct physical contact with body fluids of an infected person (vomit, urine, blood, feces, breast milk, semen ... sweat, however, would be less contagious). In other words, contamination occurs by touching the skin of a wearer of sick or dead virus or contaminated liquids. As the disease progresses, the person is contagious. Unlike the flu, airborne transmission was never identified . This explains why the disease is most commonly spread within families or relatives.

Are there a treatment against Ebola?

For now, scientists are still in the experimental stage . Two sera show promise and have been tested on patients. The Zmapp is an "artificial serum" antibody taken from mice compound. These prevent the virus from infecting cells and thus replicate in the body. Another track, the TKM-Ebola , which addresses three of the seven proteins comprising the virus. A well-treated patient survived American (it is not known whether this is due to the drug). Preventive side, no vaccine has yet been approved by the WHO . However, a Canadian laboratory tested VSV-EBOV animals with very promising results. The race between science and the disease advances every day.
