Scientists discover a new way to fight malaria epidemic

Scientists discover a new way to fight malaria epidemic

Malaria is the biggest killer of children it causes the death of a million people a year

Most of them children under the age of five in Africa
  
British scientists have discovered a new way to fight the malaria epidemic, which is the deadliest global diseases.

The British newspaper The Independent that the discovery done by scientists from the Institute of the Wellcome Trust Sanger in Cambridge gives hope of ending this disease globally thanks to the discovery decisive element in the red blood cells of human and which seems to be a key element to complete the malaria parasites life cycle within the human body, which leads to identify the weak point of the disease.

The newspaper reported that work behind the disclosure, which was published in the newspaper / The Journal Nature / focus on the second phase of the life cycle of malaria in the human body after leaving the liver to invade red blood cells during what is known as phase / Aloksoma / as scientists were able to identify human protein called / Basigan / on the outer membranes of human red blood cells, which appears to be parasites need to open the cell membrane and the invasion.

The newspaper quoted Julian Renner, a doctor from the Institute / Sanger / saying he was discovered lock protease decisive on the surface of red blood cells of human that allows the introduction of mosquitoes for the key and then the disease adding that he could interaction between the malaria parasite and red blood cells that form the basis of making vaccine saves millions of people.

He explained Reiner that malaria parasites move between mosquitoes and humans, but the stage that cause the occurrence of symptoms is when invade red blood cells of human because they need to enter the cells to carry out the division and proliferation and doubled prepared and which is essential to the continuation of parasites alive, but it a potential target for attack.

The newspaper said the scientists were able to identify the main protein / future / red cell membrane and used antibodies have been designed for future adhesion protein replication for the parasite to prevent the parasite from the use of the key that opens the lock of red blood cells.

The newspaper said that scientists believe that this matter could mean the possibility of the vaccine industry prevents the development of these parasites inside the patient's body is nothing to prevent the occurrence of disease and transferred through mosquitoes.

Malaria is the biggest killer of children it causes the death of a million people annually, most of them children under five years of age in Africa.

The scientists spent decades in an attempt to devise vaccines that protect people from infection or can control the growth of parasites if entering the human body, but the complexity of the life cycle of the parasite foiled manufacture effective vaccines.

Liquid metal mercury knows no geographical boundaries in polluting the environment?

Liquid metal mercury knows no geographical boundaries in polluting the environment?

Day after day increasing environmental pollution and among the most dangerous pollutants that are growing dangers and harms is metal mercury pollution? The mercury does not stop at any geographical boundaries in pollution of the environment is completely different from any material environmental contamination as it spreads quickly and farther distances through rivers, lakes and even oceans and before that unnoticed.

Contain the world's oceans on the amount of mercury estimated to total about 50 million tons, while estimated concentrations in the soil between 0.01 - 0.06 ppm, and rises in the rocks to end 0.09 ppm, and its concentration in the air of the world what 2 - 5 ng cubic meter . increasing year after year these concentrations to pose a real problem in the world and attention to the question of the importance and dimensions of the risk of mercury, especially in the last three decades.

Enters mercury and its compounds in many industries, where used in paper industries and electrical such as producing light bulbs, batteries and chemical industries such as dyes and other pharmaceutical industry in the production of Alakakiratabah and some types of make-up unchecked in making dental fillings and thermometers in the production of chemical solutions, as well as in the production of fungicides.

It features a mercury from other metals بميله severe lipid soluble and accumulate in living organisms, especially the human where targeted fatty tissue or organs rich in fat, including the brain, which occurs damage cells of the brain and leads to symptoms seriously ill in the nervous system of humans can also absorbed the human body mercury through several sources such as flogging, Lung, and after absorption moves with blood through the circulatory system and then some members such as the liver, kidneys and bone store and who is affected significantly with serious disorders of the digestive system, urinary and heart and the rest of the body.

When exposure to mercury vapors it happens dryness in the throat and mouth, and lead to infections in the mouth, gums and teeth fall out, chills, and potentially mental disorders ... is also affected by human mercury compounds through pollution of air mercury and the maximum allowed for organic mercury compounds 0.01 mg in per cubic meter in the air. In case the inhalation of those substances, or absorbed through the skin, they lead to erratic performance of the nervous system and a jerk as well as difficulty with speech and narrow in the field of vision or the so-called vision tunneling, as able Mercury transit through the placenta of pregnant mothers to fetus during pregnancy has proved tests of red blood cells that mercury concentrations in Kiryat embryos outperform by 28% on its concentration in blood cells of mothers. Overall Unfortunately and Mundaam 1953 the anniversary of incidents Alolimitan "Minamata then incident Niigata" in Japan, which has killed hundreds of result of pollution and mercury poisoning and to Today there are thousands of victims fall per year of mercury pollution.

Human exposure to mercury from several different ways, which include mostly by eating certain foods that contain mercury or mercury-contaminated. On or through the atmosphere polluted with mercury from burning fuel such as coal and oil, which contains large proportions of mercury, in addition to the organic mercury compounds are widely used as a pesticide for fungi and insects in the field of agriculture, which contaminate crops covered by the rights of the fruit or vegetable. It is worth mentioning that the mercury in its organic state is the most contaminated among other mercury compounds and thus poses a significant risk to human health due to the severity Ttaarh, also inorganic mercury compounds when mixing water into organic mercury compounds.

 Are also transmission of mercury to the atmosphere by pollutants laboratories that use mercury in their industries, and moves to our food through the soil and what they contain contaminants that come from industrial waste that is neither treated wastes which contain quantities elevated mercury also turns mercury into drinking water from during its transfer from soil to surface water or groundwater, where mercury compounds degrade to elements or mercuric ions or ions Zibakoz. Are stored mercury compounds by sticking sediments, where liberated very small amounts of mono and dimethyl mercury into the water by microorganisms, and then absorbed by many organisms, including fish and other wild animals domesticated and non-domesticated and agricultural crops and entering all in the human diet and concentrations of mercury so high levels. . In rivers, the former would receive fresh accumulation of mercury in algae, algae and plankton, which is considered an excellent food fish rivers and thus moves mercury Oissa to these fish and then to humans.

The recent scientific study revealed that the steam from the fuel combustion process to the atmosphere to fall back again in the form of showers of toxic mercury molecules absorbed by aquatic ecosystems on Earth and cause food poisoning and crops

The British newspaper The Guardian reported that American researchers confirmed that thousands of tons of mercury vapor rising into the atmosphere annually with the passage of time is oxidized mercury and coming back to earth with rain or snow.

The world Supervisor study Seth Lehman that bacteria in the upper atmosphere turned oxidized mercury to a substance mercury methyl that can enter the food chain with great ease, adding that the mercury that emerged in an area on the surface of the earth falls away from the original source confirms degeneration with rain or Althelouh that falls to the ground.

Lehman said that the upper atmosphere is a chemical reactor to make the mercury more able to engage in environmental systems.

And mercury do not stop at any geographical limits of contamination in the environment which is totally different from any material environmental contamination as it spreads rapidly and farther distances through rivers, lakes and even oceans and before that unnoticed.

And mercury seeping into water from unprotected plants of security and safety rules where exploited fish directly to hit the markets and dining tables, causing damaged in the nervous system and network arteries in the human body.

Global warming will exacerbate the food crisis

Global warming will exacerbate the food crisis

Oxfam warned in a report today that the storms, droughts recent which led to the rise in food prices is only the introduction of what will happen when bad exacerbated by global warming.

The Associated Press quoted the French Kelly Dent of the British non-governmental organization as saying that this will increase the seriousness with high frequency Climate change and the impact of agriculture ramifications of this.

Dent added that while the climatic phenomenon to rising prices, this translates shocked doubling the poorest, noting that they have to face higher prices for food at a time destroyed by natural disasters their homes and farms.

The FAO report noted a rise in the prices of British wheat, corn and sorghum by violent weather events that plunged tens of millions of people in poverty during the last 18 months.

According to the organization caused a heat wave in Russia and Ukraine in the last year, an increase in global wheat prices ranged between sixty and eighty percent in the three months as well as in April this year, these prices rose by 85 percent compared to what it was in June 2010.

During last July white maize prices rose in Somalia by 393 percent from the average in the last five years, while corn prices jumped in Ethiopia and Kenya Pencpti 119 and 116 percent respectively due to the drought that hit the Horn of Africa.

During the same period storms and hurricanes in the Southeast Asia to the high price of rice in Thailand, Vietnam and hovered proportion of this rise in September and October between 25 and 30 percent compared to what it was a year ago.

The World Bank reported in November of surveillance report issued by the global index of food prices still higher than in September last year by 19 percent.

This green fund which will provide a hundred billion dollars a year to the poorest countries from the year 2010 will be on the agenda of the Durban conference.

The Oxfam said that a group of experts on climate confirmed recently that global warming has accelerated the pace of heat waves and heavy rains unexpected breadth of these phenomena and called on States which will meet from today that significantly reduces carbon dioxide emissions, and establish the fund allocated to help poor countries.

Discover a planet is most like Earth orbiting a star like the sun

Discover a planet is most like Earth orbiting a star like the sun

Scientists announced the discovery of a planet is more Earth-like planets discovered orbiting a star just 600 years light is an important finding in ongoing efforts to find out Is there life beyond the solar system.


He joins the planet, called the (Kepler -22 B) to the list of discoveries includes more than 500 planets orbiting stars beyond the solar system. Which is smaller and the best location because there is liquid water on the surface of the elements necessary for life on earth.

Said Natalie Batallha vice captain of the Space Telescope Science Kalpr of the Department of Aviation and Space Administration (NASA), U.S., who discovered the star, "We are focused on monitoring the planets in the size of the ground which can be found by life."

The scientists said their findings in which is due to be published in the Astrophysical Journal that this is the first discovery of a planet with potential for life orbiting a star like the sun.

The Batallha a news conference at Ames Research Center NASA in Moffett Field, Calif. "We do not know anything about the planets that range in size between the Earth and Neptune because we are in our solar system there are no models of such planets. We do not know which part will be rocky and any part that contains the reservoirs of water and any part that contains the reservoirs of ice. do not have any idea until we measure one of them and see what they do. "

And if Kepler -22 B surface and atmosphere are similar to the land of the temperature it will be 22 degrees Celsius, about the same temperature in the spring day on the ground.

Among the 2326 planet candidates Kepler team found there were 10 in almost the size of Earth are found in sites makes them suitable for life during the turn-around on the stars

Kyoto international climate protection in the wind???

Kyoto international climate protection in the wind???

Canada and China withdrew and the United States of America did not sign the original treaty, Russia and Japan announce that they would not sign the extension of the treaty does Kyoto treaty became international climate protection on paper? Is the Kyoto Treaty will remain the only international solution to climate change?

Said Canadian Environment Minister "Peter Kent" told reporters in Ottawa: "As we have said, Kyoto for Canada is something of the past We use our legal right to withdraw formally from the Kyoto treaty." The announcement of Kent after marathon talks on climate concluded a few days ago in the coastal city of Durban in South Africa. Thus Canada, a major energy producer in the world, the first country to announce its withdrawal from the Kyoto Protocol.
And has justified the Canadian Environment Minister his country's decision that: "the Kyoto Protocol does not include the two Sahpti greatest emissions, namely China and the United States of America, and therefore ineffective. Has become clear by now that the" Kyoto treaty "is not the right way for the solution of international climate change but an obstacle. "
But does the withdrawal of Canada is the only loss of that treaty? This has led Canada's withdrawal from the treaty to another slap to the Kyoto Protocol, which had already been weakened and expire in December / December 2012. Along with a hint of Canada and Russia and Japan that it would not sign the extension of this Treaty. Experts said that Canada, withdrawing before the end of the year, will avoid penalties for failure to meet its commitments to reduce binding greenhouse gas emissions.
He also added Canadian Environment Minister "Kent": Meeting the Kyoto Protocol targets for 2012 would be equivalent to either prevent the functioning all cars, ambulances and police vehicles of all types on the roads Canadian or close the agricultural sector completely and cut heating for all homes, offices, hospitals, factories, and buildings in Canada. " The Kent at the same time that Canada is making "tremendous progress" toward reducing carbon dioxide by 17 percent by 2020 from 2005 levels, a goal is voluntary and signed after the United States by announcing a similar commitment. said that Canada would like to see new agreement includes legally binding commitments for major countries responsible for emissions.

We have accepted all the countries Canada's decision this sharp criticism but the criticism started from within Canada itself Opposition parties have accused the Canadian Environmental Minister of spreading the spirit of fear among the people .. At the international level, spokesman Chinese Foreign Ministry, "Liu Weimin," in an interview, saying: "It is unfortunate and contrary to the international community's efforts to withdraw Canada from the Kyoto Protocol at a time made it a meeting Durban significant progress to ensure a second phase of commitment to the Protocol, expressing hope to play Canada responsibilities, duties and continue to observe its commitments and adopt a positive and constructive towards participation in international cooperation to respond to climate change. also considered the German government on the San German Environment Minister that Canadian decision was not surprising, and I have asked the German Green Party to take action against this decision. as expert called party green on energy matters "Hans Joseph Fil" to boycott oil supplies Canadian form fields that is extracted from significant damage to the environment. On the other hand described the Minister of the Environment of Japan, "Joshi Hosono" Canadian decision Palmasv urged Canada to continue in the Convention, saying that the framework Kyoto includes "important elements" that could help in the fight against climate change. also said an Indian official said Canada's decision could jeopardize losing any gains in meeting Durban. As "Greenpeace" active in the field of environmental protection describing Canadian decision "insulting political to the international community. "
And will remain controversy existed between the countries of the world and among the signatories to the Kyoto Treaty and between and among the signatories between supporters and opponents and will continue to address the problem of climate change in the wind??

Fears of increased drug residues in water

Fears of increased drug residues in water

It's time to actually reduce pollution pharmacist after an increase in frightening signs that point to its spread in the water, although this did not cause pollution, harm to humans so far.

The water that pours from faucets or taps U.S. homes pure, clear and generally safe, although delicious drink of feeling may not feel up to eating a bowl of water natural springs. And in the United States are monitoring about 170 thousand of public water systems for the detection of nearly 80 harmful substances. These include the types of prohibited substances harmful bacteria, viruses, pesticides, petroleum products, and strong acids and some minerals.

However, water quality experts and environmentalists seem to growing fears of another type of pollution caused by chemicals found in prescription drugs and those that are sold without a prescription, that leaks water around lakes and rivers and streams. The contaminated water also perfumes and cosmetics and Alcolonya skin and sun protection products that leaks when washing the skin and face.

So far there is no evidence of any fact that in the pharmaceutical and personal products in the water harmful to humans, but studies suggest that their adverse effects on aquatic life.
This has led the restoration of medicines, which allows any person re-medication is used to specific locations to achieve two goals: first, removal of drugs from water, and the second: to prevent the use of certain medications such as painkillers containing opium addiction or for the purposes of the law.

And represented the instructions issued by the Environmental Protection Agency (EPA), the second step in the right direction, since it dealt hospitals and care homes not to throw the unused medicines in the public sewers or toilets. Guidelines have also been the general public for most of such drugs is used. However, the question arises now is whether these steps are sufficient to prevent the leakage of chemical compounds of pharmaceutical and personal products and prevent the rapid accumulation in the water.

Sources of pollution pharmacist

• Despite the difficulty of reliable revenue numbers, it can be assumed that we are as a sound assumption of consumers we are responsible for a large percentage of pharmaceutical substances and preparations that leaks about personal water lakes and rivers and streams.
• American homes contain a lot of unused medicines that over time expired. It has been assumed drug recovery program in California in 2007 that half of those medicines and lotions are thrown. It may be that high a figure, but it means that a large proportion are still thrown in the water.
• Chemicals are also up to the water of the drugs we use, since our bodies absorb most of the parts of the medicines that we eat, and the rest of the parts is the word through the urine or stool (or through sweating), and thus it is up to the water. An increasing number of drugs that are produced in the form of ointments or creams or lotions, therefore, some materials that do not absorb a potential problem of contamination when washing the skin. Accounts have been developed, for example, that the use of testosterone cream for man to lead him to enter the amount of water equivalent to when he spoke bodies of 300 men.
• Health care institutions are another source of pollution sources, pharmacist, hospital and are less polluting than the role of care here because I have a pharmacy medicines can be returned to them, while aimed at the role of pharmaceutical care after the death of the patient or transfer them.
• Drug production companies play a role in some of the pollution pharmacist varying degrees, have been made to study the U.S. Geological Survey Water Pollution current close to the two laboratories for the production of drugs in the District of New York at rates exceeding 10 to 1000 times the rates of pollution in other parts of the United States.
• Agriculture is another source of contamination of the main Valmkhalafat of animals weighing up two trillion pounds (about 900 billion kg) of poultry and livestock are full of hormones and antibiotics given to animals to increase their growth and maintain their health, which is bound to reach some of these substances into the groundwater.
