Magnesium requirement for our body

Apparently there are peanuts in peanut benefit more because in these foods have a high magnesium content.

Magnesium is one mineral that plays an important role in the metabolism of the body. Why does the body need magnesium? Because these minerals are multifunctional and indispensable each cell to produce energy. Magnesium body needs to produce 300 kinds of enzymes, and sending messages through the nervous system, making the muscles remain supple and relaxed and maintain strong bones and teeth. Another important function is to maintain consistency rate / rhythm of the heart and blood pressure remained normal.

In many studies, the role of magnesium is also needed in addressing a number of diseases such as asthma and diabetes. This mineral is also proved very important in dealing with cardiac rhythm disturbances or abnormalities. Magnesium is also needed role in the absorption and use of various vitamins and other minerals. Vitamin C and calcium for example, will work perfectly in the body when the magnesium requirement is fulfilled.
Magnesium Requirements: Men and women differ
In the human body, the total reached about 25 grams of magnesium. Most magnesium is concentrated in bones and teeth, but also present in muscle and blood. Sufficient numbers in the body is very important to maintain balance the body’s metabolism.

To keep the levels in the body remains the ideal. Magnesium intake can be done either through daily food and additional supplements for the needy. Total magnesium intake is recommended every day is different for gender and age period. Adult men aged 13-30 years for example, requires approximately 400 milligrams of magnesium intake per day, while women 19-30 years 310 mg per day. Research on magnesium requirement continues to grow. Most nutritionists and doctors who recommend intake of 500 mg of magnesium per day for adults. This number is believed to help maintain normal blood pressure and avoid permanent heart condition.

Magnesium For Our Heart
June 15th, 2010 In order to get enough nutrition so you can eat foods that rate high magnesium such as nuts, beans, dark green vegetables, whole grains and seafood. Magnesium also needs can be met from consumption in each glass of milk because there are about 34 milligrams. From soy foods like tofu, Tempe and soy milk are also rich in magnesium.

Although the types of foods that contain magnesium diverse, it is not easy to fulfill the minimum required each day. However, these foods are the best way to meet the body’s need for magnesium and other types of vitamins or minerals.

If you want to get extra via supplements, keep in mind that you do not need magnesium in large quantities. Supplements may only be giving you between 10 to 50 mg, because when too much – more than 600 mg of-your risk of contracting diarrhea.

Should also note also that magnesium supplements are usually combined with a number of hazardous substances. The options available are also varied ranging from magnesium oxide, magnesium ototat, magnesium gluconate, magnesium aspartate, magnesium glycinate or magnesium citrate. Choose the type of aspartate, glycinate and citrate because it will be easily absorbed by the body. While this type of oxide should be avoided because it will be difficult to tolerate the body.

Strengthens your heart
As revealed in the beginning, magnesium plays vital for heart health. From some research was revealed, the low levels associated with a number of cardiac abnormalities.

Magnesium deficiency can lead to stiffness or spasm in one coroner arterial vessels, so that disrupt blood circulation and cause a heart attack. Numerous medical experts argue magnesium deficiency is behind the case of a heart attack, especially in patients who had no history of heart disease. Facts show that an intravenous therapy (IV) magnesium is often used for patients with severe heart failure.

Magnesium is also important in protecting the body from heart attacks caused by clots or blood clots. This mineral helps prevent formation of clots by making platelets or blood chips become less “sticky” so that tends to be difficult to blend in to form clots.

The lack of magnesium may also lead to cases of cardiac arrhythmias or irregular heart rhythm. This disorder sometimes makes the heart beat of loss or gain one or even tapping in rhythm once it became even too fast. If interference is more serious and heart rate did not immediately return to normal, your risk of sudden death.

Now that you your heart strong and avoid a heart rhythm abnormality, get used to fulfill the magnesium intake by eating healthy foods and balanced every day. Magnesium sufficient, then kept on beating heart!

Seven atom transistor sets the pace for future PCs

Researchers have shown off a transister made from just seven atom that could be used to create smaller , more powerful computer.
Transisters are tiny switches used as the building blocks of silicon chips. If the new atomic transister can be made in large numbers it could mean chips with components up to 100 times smaller than an existing processors.
The Australion creators of the transister hope it is also a step towards solid - state quantum computer. The transister is not the smallest ever created as two research group have previously managed to produce working single atom Transister.
However, the device is many times smaller than components found in chips in contemporary computers . On chips where components are 22 nonometers in size,transister gates are about 42 atoms across.
The working transister was created by replacing seven atoms in a silicon crystal with phosporous atoms.
"Now we have just demonstrated the world first electronic device in silicon systamatically created on the scale of individual atoms" said proffessor Michellie Simmons, lead resercher on the project at the University of New south wales.
Moors' Law predicts that the amount of memory that can fit on a given area of silicon, for a fixed cost double every 12-18 months. The limit of this prediction is being tested as component get over smaller and their compitationally useful properties become less reliable.
If an entier chip could be made with every one its billions of transisters made from the sillocon crystals, it cuold mean an 'exponential' leap in processing power.
The resechers are in a long wayfrom a commercial process because the Tiny transister they created was handmade. The team used a scanning tunnelling microscope to move the phosporous atom in the space.The work on the transister is being carried out as part of a larger project to create a "Quantum Computer".

Phoenix Fate

The static Spacecraft,Which was sent to study the planents " high arctic" lost contact with the earthin late 2008.Phoenix would have been covered by corbondi oxide ice, and Nasa always said it was likely the mission would be destroyed in such harsh condition.
The latest pictures taken from orbit show phenix to have a smaller outline, indicating it was badly damaged. "Before and after images are dramatically different" said Micheal mallen of the university of colorado in Boulder, a science team member for both phoenix and the Hirise camera on the Mars recoonnaissance orbiter which aquired the data.The Lander looks smaller, and only amportion of a difference can be explained by accumilation of dust on the lander , which makes it surfacess less distinquisable from surrounding ground.
The differnces in the pattern of shadows is said to be consistent with the prediction of how phoenix could be damaged by the buid up of frost.
It was expected the panels would bend and bucle under the weight of many tens of kilos of ice.Launche from earth in August 2007, the robot arrived arrived on Mars on 25 May 2008, landing further north than any previous mission to the martian surface.
To make it down, the probe have to survive a fiery plunge through the red planets thin admosphere , releasing a parachute and using a thrusters to controle it descent.
During it ground operation ,the Robot dug, scooped, baked, snuffed and tasted the martian soil to test whether it has ever been capable of supportinf life.
Phoenix major achieven\ment was in becoming the first mission to mars to 'touch water' in the form of water ice it found just centemeter below the top soil.Chunks of icewere seen tovapourise before the lander's camera.

Electirc car

With a 0-60mph acceleration of four seconds, this high-adrenaline experience blew away forever the stereotypical image of electric vehicles, the plodding milk-floats I'd known since my childhood.

But if battery power can be cool is it ever going to be practical? The question has urgent relevance as the coalition government declares its aim of pushing for an electron revolution on our roads.

A timely report by the Royal Academy of Engineering lays out the reality of turning some of Britain's 30 million cars electric in coming decades. The conclusion? The challenges are do-able but also pretty daunting.So, getting started in first: can the batteries ever be made cheaply enough to tempt consumers? If they're big enough to get you a reasonable distance, they may add thousands to the price and potential consumers may think twice.And how long will the batteries last? It depends on the type but typically they should be good for at least 1,000 charges which should give you at least three years' use.And just as mobile phone batteries have become smaller and lighter, innovation should also drive improvements in vehicle power sources too.

Second gear, charging-up: some 4,000 charging points are due to be installed in pilot schemes in the North-east, Milton Keynes and London this year.A good start, according to the authors, but what if you don't have off-street parking?

As Professor Kemp said: "You can't exactly have cables running out through the letter-box across the pavement into the street. And if it's raining, are you really going to park at a charging point a mile down the road from your house?"

'Chicken and egg'

Third gear, charging at your destination: what happens if thousands of electric car drivers descend on one spot - a football match, for example - and all want charging in the car park at the same time? Who pays for that infrastructure and who'll organise it? It's what Professor Kemp calls "a chicken and egg situation": charging-points won't be installed up and down the country until there are plenty of electric cars on the roads. And people won't buy electric cars until they'll be able to get a fill-up.Fourth gear, the bills: at the moment, electric car ownership is encouraged with tax breaks. Right now, this doesn't cost the government much in lost revenue. But what if half the country's cars are exempt from Vehicle Excise Duty? How would the Treasury react then? The authors say a long-term policy on incentives is essential.

At current prices, a full charge for a typical electric car might cost about £2 - drawing enough power to drive about 161km (100 miles). Not bad compared to conventional fuel.

Finally, fifth gear, the carbon value: plug-in cars will only be as green as the electricity they're using. According to the report, electric cars powered by the current mix of sources are only "marginally greener" than the most economical petrol or diesel cars.

In an earlier report, the Royal Academy of Engineering had mapped out the scale of the task involved in moving to a low-carbon electricity supply - with a mix of energy efficiency, renewables, nuclear and clean coal. This new report adds urgency to the calls for decisions as soon as possible.

Speeding ahead

The key development, says Professor Kemp, alongside a move away from fossil fuels, is a so-called "smart grid". Backed by the coalition, this is an intelligent network in which demand better matches supply.

If cars were programmed to be charged at night, when demand is low, rather than at peak times, then their impact on power generation could be minimised.So, what are the chances of our next cars being electric?Professor Blythe, who's studying consumer reaction to battery-powered vehicles, reckons 5-10% of British cars will be electric within 10 years.Just back from a motor show in Yokohama, he says the Japanese are at least a year ahead of us - even experimenting with "inductive charging" where cars can be refuelled without a cable connection but by parking over a special plate.The potential for change is clearly massive but weaning British motorists off liquid fuel will be an uphill task, as the authors acknowledge.

"Cars are iconic," says Professor Kemp, "and central to our contemporary culture. In Britain, you would not get 6.4million people tuning in to TV programmes called Top Domestic Appliances or Top Condensing Boilers in the way they do for Top Gear."Top Battery? Top Charging Point? Let's see.

Planet swallow by parent Star

The Hubble space telescope has observed a planet being swallowed by its parent star.The hottest known planet in the milkyway Galaxy. According to Nasa the planet is so close its sun like planet star that tidel forces have streched the planet in to an egg shape and its so hot that it has expanded to the point where its outer atmosphere "spills in to the star" Scientist expect the star to consume the planet in 10 million years

Ancient Tombs and Mummies Found

Archeologists have unearthed 57 ancient Egyptian tombs, most of which hold an ornately painted wooden sarcophagus with a mummy inside.

photo released by the Egyptian Supreme Council of Antiquities on Sunday, May 23, 2010, shows a painted wooden sarcophagus discovered in Lahoun, near Fayoum, some 70 miles (100 kilometers) south of Cairo, in Egypt.
The Supreme Council of Antiquities says archeologists have unearthed 57 ancient Egyptian tombs, most of them containing a painted wooden sarcophagus with a mummy inside, with the oldest tombs dating back to around 2750 B.C. and twelve of the tombs belonging to the 18th dynasty which ruled Egypt during the second millennium B.C.

Hammerhead shark mystery solved

The shape of the Hammerhead bringsfurther benefits, the researchers discoverd By moving their heads sideways as they swim, the shark can see much of what isbehind them.More extraordinary is that the position of eyes allows the shark to see through 360 degrees in the vertical plane meaning the animal can see above and below them at all times. As well as improving their ability to catch prey, this may be beneficial to smaller shark that are potential prey to larger shark.

A step closer to 'synthetic life'

The synthetic cell looks identical to the 'wild type'

Scientists in the US have succeeded in developing the first synthetic living cell.
The researchers constructed a bacterium's "genetic software" and transplanted it into a host cell.The resulting microbe then looked and behaved like the species "dictated" by the synthetic DNA.The advance, published in Science, has been hailed as a scientific landmark, but critics say there are dangers posed by synthetic organisms.The researchers hope eventually to design bacterial cells that will produce medicines and fuels and even absorb greenhouse gases.
The team was led by Dr Craig Venter of the J Craig Venter Institute (JCVI) in Maryland and California.He and his colleagues had previously made a synthetic bacterial genome, and transplanted the genome of one bacterium into another.
Now, the scientists have put both methods together, to create what they call a "synthetic cell", although only its genome is truly synthetic.

Dr Venter likened the advance to making new software for the cell.The researchers copied an existing bacterial genome. They sequenced its genetic code and then used "synthesis machines" to chemically construct a copy.Dr Venter told BBC News: "We've now been able to take our synthetic chromosome and transplant it into a recipient cell - a different organism.

As soon as this new software goes into the cell, the cell reads [it] and converts into the species specified in that genetic code."

The new bacteria replicated over a billion times, producing copies that contained and were controlled by the constructed, synthetic DNA.

"This is the first time any synthetic DNA has been in complete control of a cell," said Dr Venter.

'New industrial revolution'

Dr Venter and his colleagues hope eventually to design and build new bacteria that will perform useful functions. I think they're going to potentially create a new industrial revolution," he said.

"If we can really get cells to do the production that we want, they could help wean us off oil and reverse some of the damage to the environment by capturing carbon dioxide."

Dr Venter and his colleagues are already collaborating with pharmaceutical and fuel companies to design and develop chromosomes for bacteria that would produce useful fuels and new vaccines.

But critics say that the potential benefits of synthetic organisms have been overstated.

Dr Helen Wallace from Genewatch UK, an organisation that monitors developments in genetic technologies, told BBC News that synthetic bacteria could be dangerous.

"If you release new organisms into the environment, you can do more harm than good," she said.

"By releasing them into areas of pollution, [with the aim of cleaning it up], you're actually releasing a new kind of pollution.

"We don't know how these organisms will behave in the environment."

The risks are unparalleled, we need safety evaluation for this kind of radical research and protections from military or terrorist misuse

Dr Wallace accused Dr Venter of playing down the potential drawbacks.

"He isn't God," she said, "he's actually being very human; trying to get money invested in his technology and avoid regulation that would restrict its use."

But Dr Venter said that he was "driving the discussions" about the regulations governing this relatively new scientific field and about the ethical implications of the work.

He said: "In 2003, when we made the first synthetic virus, it underwent an extensive ethical review that went all the way up to the level of the White House.

"And there have been extensive reviews including from the National Academy of Sciences, which has done a comprehensive report on this new field.

"We think these are important issues and we urge continued discussion that we want to take part in."

Ethical discussions

Dr Gos Micklem, a geneticist from the University of Cambridge, said that the advance was "undoubtedly a landmark" study.

But, he said, "there is already a wealth of simple, cheap, powerful and mature techniques for genetically engineering a range of organisms. Therefore, for the time being, this approach is unlikely to supplant existing methods for genetic engineering".

The ethical discussions surrounding the creation of synthetic or artificial life are set to continue.

Professor Julian Savulescu, from the Oxford Uehiro Centre for Practical Ethics at the University of Oxford, said the potential of this science was "in the far future, but real and significant".

"But the risks are also unparalleled," he continued. "We need new standards of safety evaluation for this kind of radical research and protections from military or terrorist misuse and abuse.

"These could be used in the future to make the most powerful bioweapons imaginable. The challenge is to eat the fruit without the worm."

The advance did not pose a danger in the form of bio-terrorism, Dr Venter said.

"That was reviewed extensively in the US in a report from Massachusetts Institute of Technology (MIT) and a Washington defence think tank, indicating that there were very small new dangers from this.

"Most people are in agreement that there is a slight increase in the potential for harm. But there's an exponential increase in the potential benefit to society," he told BBC's Newsnight.

"The flu vaccine you'll get next year could be developed by these processes," he added.

ice on fire

IF that much UNMELTING ICE FORMATIONS of hundreds of years was required by Nature to put a cap on the EXPLODING POLAR VOLCANOES then one can imagine the HEAT COMPRESSED AND DEPRESSED INSIDE THE CORE OF THE EARTH for so many years....SOMETHING that will make us think that had it not been for the ICE-CAPS the EARTH would have been a FURNACE OF FIRE AND SOOT and BRIMSTONE.......


Russia, US may jointly develop spacecraft engines

       Washington, May 18 (IANS/RIA Novosti) Russia and the US may soon reach an agreement on the joint development of new engines for spacecraft designed for exploration of deep space,a Russian deputy prime minister said.Sergei Ivanov said Monday during a US visit that future exploration of outer space will require nuclear-powered engines for carrier rockets and spacecraft, and work on these costly development projects should start as soon as possible.A decision (on Russian-US cooperation in this area) may be adopted soon, probably during the upcoming visit of Russian President Dmitry Medvedev to the United States,' Ivanov told reporters in Washington.
      US President Barack Obama wants to cut NASA's development of a new carrier rocket and turn launches of astronauts over to private companies. His plans have been criticised for leaving the US overly reliant on Russia for missions to the International Space Station (ISS) after the Space Shuttle fleet is retired later this year.
     Ivanov said Moscow and Washington had been effectively cooperating in the sphere of space exploration but with the expiration of the service life of the ISS in 2020 both countries should have new space projects to apply their joint efforts.
     'It is a very ambitious task, a serious challenge both in technological and financial terms. That is why we realise that we can achieve the goal only by joining technological and financial efforts of both countries with participation of international community,' Ivanov said.

     The Russian government allocated 500 million rubles ($16.7 million) in 2010 to start a project to build a spacecraft with a nuclear engine. NASA started a programme to develop a nuclear propulsion system in 2003, and spent several hundred million dollars on the project before cutting it back.
      The head of the Russian Federal Space Agency Roscosmos said in January that the draft design of spacecraft powered by a nuclear engine would be finalised by 2012, and the financing for further development in the next nine years would require an investment of at least 17 billion rubles (over $580 million).
       Anatoly Perminov said nuclear engines for spaceships were a very promising area and should be created to make flights to Mars and other planets. Solar power is used for missions to the inner planets, but at distances beyond Earth's orbit the sun's energy is too weak to be used as a power source.

deppression among youths

     Washington: Six months of switching medication or combining a medicine switch with cognitive behavioural therapy could help more than one-third of teenagers with treatment-resistant depression – many of whom had been depressed for more than two years, revealed a multicenter study led by UT Southwestern Medical Center researchers.

      The study found that teenagers who showed an improvement of symptoms after just three months into their new regimen were much more likely to show lasting beneficial effects.
           This study provides hope for parents and teenagers that persistence in seeking treatment will lead to recovery in some patients, especially if early treatment is aggressive. Even after six months of treatment, however, about two-third of teenagers were still suffering from at least some symptoms of depression," said Dr. Graham Emslie, professor of psychiatry and paediatrics at UT Southwestern and a principal investigator of the study.
          The 334 study participants ranged from 12 to 18 years of age.
They exhibited traits of moderate to severe major depressive disorder, including thoughts of suicide. Historically, these types of patients have the worst treatment outcomes.

        In February 2008, Emslie and colleagues first published work about these teenagers, who had failed to respond to a class of antidepressant medications known as SSRIs, or selective serotonin reuptake inhibitors.

       SSRIs, are the most common drug treatment for depression, although about 40 percent of teenagers on the drugs don''t respond to the first treatment.

      After three months, nearly 55 percent of the teens in the study improved when they both switched to a different antidepressant and participated in cognitive behavioural therapy, which examines thinking patterns to modify behaviour.
     The study also found that after three months, about 41 percent of participants showed improvement after just switching to either a different SSRI or to venlafaxine, a non-SSRI type of depression medication.
     The researchers have now examined the six-month data from that study, and found that nearly 39 percent of participants who completed six months of treatment no longer had symptoms of depression.
     Those participants were more likely to have had lower levels of depression, hopelessness and anxiety at the beginning of the study.
     Those who responded to the new regimen during the first three months were more likely to achieve remission, meaning minimal symptoms of depression or no symptoms at all.
     Many of those participants, who came from six sites across the country, responded during the first six weeks of treatment.
    Current treatment guidelines suggest staying with a treatment for at least two to three months before trying another treatment.
   "In light of our new findings, those guidelines may need to be revisited because these latest results suggest more aggressive treatment early on may improve outcomes," said Emslie.
    The study has been published in a future edition of the American Journal of Psychiatry.

Vitamin D improves quality of life in old age: Study

         Vitamin D, which helps fight a host of diseases, may also keep people mobile in their golden age, a new study has claimed.
         The Wake Forest University study found that elderly people with the highest levels of vitamin D had better physical function and mobility than others.
        "Those with better vitamin D levels started out better and ended up better on physical performance tests," study author Denise Houston, a professor of internal medicine at the University, was quoted as saying by WebMD.
          The study tracked 2,788 seniors with an average age of 75 for four years and assessed vitamin D status by analysing each person's blood for 25-hydroxyvitamin D -- a precursor activated vitamin D.
The researchers looked at how quickly each participant could walk a short distance about, six yards, and rise from a chair five times, as well as balance tests.
         They found physical function declined during the study period, but it remained significantly higher among those with the highest vitamin D levels at the beginning of the study.
"Over time, everybody declined in the tasks, as expected," Houston said.
         However, those who started out with higher vitamin D did better on the tests than those whose vitamin D levels were lower at the start.
        "People who had higher levels started out with better physical functioning and because they started out better, they remained at higher physical functioning," she said.
        "Those with adequate or optimal vitamin D status [the highest group] had approximately 5 per cent higher physical performance scores and 5 per cent faster walk speed on the 400-meter walk compared to those with insufficient vitamin D status at the 4-year follow up," she added.
          Next, Houston wants to focus on whether vitamin D blood levels can predict disability in older adults and whether supplements can ward off disability and mobility problems.
          The findings were presented at the American Society for Nutrition at the Experimental Biology meeting in Anaheim, California.

Have aliens been visiting Earth

Accusing world famous astrophysicist Stephen Hawking of spreading misinformation about threats from aliens, former Canadian defence minister Paul Hellyer claimed recently that extraterrestrials have actually been visiting earth for decades.
Rather than harm mankind, he said, their (aliens') spaceships have provided us information for triggering today's microchip and IT revolution on our planet.
Hawking has recently warned humanity against contacting aliens. According to Hawking, if human beings tried to contact aliens, they could invade us and take away our most important resources.
Hawking has also said that though most extraterrestrial life could be only in the form of small animals, there could also be “nomads, looking to conquer and colonize” other planets.
Hellyer told the Canadian Press that “the reality is that they (aliens) have been visiting earth for decades and probably millennia and have contributed considerably to our knowledge.”
He said our computer screens have their origins in alien spaceships.
Blaming Hawking for scaring mankind about aliens, he said, “He (Hawking) is indulging in some pretty scary talk there that I would have hoped would not come from someone with such an established stature.
