The manta ray (Manta birostris) is the largest species of the rays. The largest known specimen was more than 7.6 metres (25 ft) across, with a weight of about 2,300 kilograms (5,100 lb). It ranges throughout tropical waters of the world, typically around coral reefs. They have the largest brain-to-body ratio of the sharks and rays.
Mantas have a variety of common names, including Atlantic manta, Pacific manta, devilfish, and just manta. At one time it was thought that there were many species of Manta. However, the modern scientific consensus has been that there is just one species, a view supported by mitochondrial DNA studies. 
Recent studies have suggested that what is called manta ray are at least two different species, one large that migrates, and another smaller one called Manta alfredi that does not. The use of this name is questionable. The species alfredi was first used in the description of Prince Alfred’s manta ray by Krefft in 1868.  Modern genetic studies have shown that Ceratoptera alfredi Krefft 1868, revised as Manta alfredi (Krefft, 1868), is a synonym of Manta birostris (Donndorff, 1798). The genus is generally considered to be in need of world-wide revision. Even the accepted name Manta birostris is often incorrectly ascribed to Walbaum (1792).

Giant manta with divers: With a wingspan of up to 7 and a half metres (25 feet), the giant mantas are much larger than the reef mantas
The Wizarding World Of Harry Potter Theme Park, Orlando
The Wizarding World of Harry Potter is a theme park based on JK Rowlingâ€™s best selling series, Harry Potter, due to open in the spring of 2010, at Universal Studiosâ€™ Islands of Adventure resort, in Orlando.
Artists have drawn artworks to show the world a small preview of the magical theme park. Letâ€™s have a look at what weâ€™ll be able to experience in the world of Harry Potter.
Hubble telescope’s latest
Please wait images are loading …..
A renewed and rebuilt US telescope is now able to send its sharpest and best quality images till date. Now Hubble Telescope is able to capture deepest images of this cosmic beauty. Earlier this year Hubble Telescope was upgraded, which included installation of two new cameraâ€™s, new instruments and replacing broken parts, with cost nearly a billion dollar. Here is a collection of most recent images from the upgraded Hubble Telescope and some images which were taken by same Hubble Telescope before the upgrade.
This image shows the planetary nebula, catalogued as NGC 6302, but more popularly called the Bug Nebula or the Butterfly Nebula. The Wide Field Camera 3 (WFC3), a new camera aboard NASAâ€™s Hubble Space Telescope was installed by NASA astronauts in May 2009, during the servicing mission to upgrade and repair the 19-year-old Hubble telescope. NGC 6302 lies within our Milky Way galaxy, roughly 3,800 light-years away in the constellation Scorpius. The glowing gas is the starâ€™s outer layers, expelled over about 2,200 years. The â€œbutterflyâ€� stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Alpha Centauri
This NASA Hubble Space Telescope image creates a picture composed of gas and dust, the pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation Carina. The image shows that astronomers are given a much more complete view of the pillar and its contents when distinct details not seen at visible wavelengths are uncovered in near-infrared light. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure.

In 1994, the foundation was formed as the William H. Gates Foundation with an initial stock gift of US$94 million. In 1999, the foundation was renamed the Bill & Melinda Gates Foundation. After a merger with the Gates Learning Foundation in 2000, Gates gave an additional US$126 million. During the foundation’s following years, funding grew to US$2 billion. On June 15, 2006, Gates announced his plans to transition out of a day-to-day role with Microsoft, effective July 31, 2008, to allow him to devote more time to working with the foundation.
Bill and Melinda Gates, along with the musician Bono, were named by Time as Persons of the Year 2005 for their charitable work. In the case of Bill and Melinda Gates, the work referenced was that of this foundation.
The scale of the foundation and the way it seeks to apply business techniques to giving makes it one of the leaders in the philanthrocapitalis m revolution in global philanthropy, though the foundation itself notes that the philanthropic role has limitations. In 2007 its founders were ranked as the second most generous philanthropists in America.
As Bill and Melinda pledge $10 billion over the next decade for vaccines in the developing world, Time magazine takes a look at what the world’s largest foundation does with it’s $34 billion endowment.
Sokoto State, Nigeria
The Bill & Melinda Gates Foundation funds education, agricultural- development and health projects around the world. In a recent grant, the foundation teamed with Rotary International and the British and German governments to help commit $630 million to fighting polio. The Bini Community Health Post, which Gates visited in February, above, is combating the disease in Nigeria, one of the last four countries in the world with a significant polio problem.
Children gather at a National Immunization Day booth to receive flags, whistles and balloons: small rewards in exchange for their bravery in agreeing to get inoculated against polio. This event was sponsored by Rotary International.
Los Baños, Philippines
In the world of agriculture, the foundation has funded organizations like the International Rice Research Institute, which received $31 million in two grants to produce a rice that is more efficient in photosynthesis and resistant to flooding and cold temperatures. These enhanced varieties will allow small farmers — many of whom live on less than $1 a day — to dramatically boost crop yields and lift themselves out of hunger and poverty.
In the fight against AIDS, the foundation, along with the global-health community, estimates that new HIV infections could be cut in half by 2015.
Before the Gateses got involved, malaria — a disease that contributes to 1 million deaths a year — garnered little attention. "We gave a small grant at first, like $30 million," Bill Gates recalls, "and everybody said, ‘Wow! That is the greatest increase in nongovernmental spending in the history of malaria research!’ And I thought, Oh, you are kidding." Since then, the foundation has committed $1.6 billion to fighting the disease.
In 2006, billionaire investor (and Bill Gates buddy) Warren Buffett effectively doubled the foundation’s endowment by pledging $31 billion. Despite its massive wealth, the Foundation remains nimble: all it takes to move billions of dollars out the door is the approval of Bill and Melinda.
Improving the American education system is a primary focus of the foundation’s work. Memphis City Schools, above, are among the beneficiaries of $335 million in grants aimed at improving teacher effectiveness and the fair and reliable measurement thereof, increasing the number of effective teachers and supporting and rewarding those teachers who are increasing student achievement. Ultimately, the foundation is committed to dramatically increasing the number of students who obtain a college or postsecondary degree.
Although the Internet can be enormously useful in accessing health, government and job information, there are billions of people around the world who can never use it. In 2002 the foundation gave a $1 million Access to Learning Award to BibloRed, the public-library network of Bogotá, shown above, to expand its technology services.
How does the foundation know if its work is paying off? As Bill himself notes, "You don’t have customers who beat you up when you get things wrong … you don’t have a stock price that goes up and down to tell you how you’re doing." Indeed, the foundation has been criticized for focusing too much on cutting-edge vaccine research instead of on more readily available tools like mosquito nets, and for providing governments with an excuse to not spend their own money. Though the foundation rejects both of these criticisms, it nevertheless insists on rigorous self-evaluation and goes further than most in revealing its failures and missteps.
As you know that The effects of global warming could be seen all around the world because on deserts, water scarcity is becoming more severe, and on tropical countries summer season are being lengthened. These things occur because the atmosphere���s absorption capacity is enhanced by both natural and man-made global warming causes. Earth quakes, eruption and green house effects diminish the world balance and human activities continually add to pollution and environmental contamination. Now that we are already experiencing these unlikely effects, we should look out for the proper solutions of global warming. Lets see what Diesel is doing for global warming through ���Global Warming Ready��� campaign.
