Gemfields said its experts "will continue to evaluate the gem before any final decision is taken in terms of its future". Ian Harebottle, chief executive of Gemfields, said: "This is a unique find. The Insofu displays wonderful colour and good translucency. Its sheer size, rich colour and fine protective biotite shell make it difficult to see deep into the gem. However, all indications suggest that the core of the emerald is competent and that it should yield a number of cut gems of significant size." The largest uncut emerald believed to have been found was in Carnaiba, Brazil in 1974. It was an incredible 86,136-carat natural beryl crystal. The stone was eventually valued at $1,120,080. The largest emerald crystal ever discovered was 7,025 carats and was found in a mine in Colombia.

As it should, Crawler Town has its own little backstory: Crawler town roams the barren wastes of a post steam-punk world after cataclysmic climate change do to excessive coal use. Several such cities exist but Crawler town is the most popular due to the Aero 500 hydrogen fuel cell Air races that are held. Many people travel the wastes to Crawler town for vacation and to enjoy rare luxuries like Pizza, fresh vegetables and Beer. Travelling the wastes in search of minerals and aquifers ( vital for survival) the mobility of the city keeps it away from the vicious sand storms of the wastes Hell, living in a wasteland doesn't sound so bad!

"How old you are matters, but beyond that it's your interpretation that has far-reaching implications for the process of aging," said Markus H. Schafer, a doctoral student in sociology and gerontology who led the study. "So, if you feel old beyond your own chronological years you are probably going to experience a lot of the downsides that we associate with aging. "But if you are older and maintain a sense of being younger, then that gives you an edge in maintaining a lot of the abilities you prize." Schafer and co-author Tetyana P. Shippee, a Purdue graduate who is a research associate at Purdue's Center on Aging and the Life Course, compared people's chronological age and their subjective age to determine which one has a greater influence on cognitive abilities during older adulthood. Nearly 500 people ages 55-74 were surveyed about aging in 1995 and 2005 as part of the National Survey of Midlife Development in the United States. In 1995, when people were asked what age do you feel most of the time, the majority identified with being 12 years younger than they actually were. "We found that these people who felt young for their age were more likely to have greater confidence about their cognitive abilities a decade later," Schafer said. "Yes, chronological age was important, but the subjective age had a stronger effect. "What we are not sure about is what comes first. Does a person's wellness and happiness affect their cognitive abilities or does a person's cognitive ability contribute to their sense of wellness. We are planning to address this in a future study."

The pileup was created in part because studios want to capture some of the excitement surrounding "Avatar," the James Cameron epic released in December. At $2.4 billion in global ticket sales, it is the highest-grossing film ever. In addition to the novelty or richer experience that might drive more people to see a 3-D movie, tickets to 3-D movies also cost a few dollars more. Around the time "Avatar" came out, Warner Bros. decided to convert a remake of "Clash of the Titans" from 2-D to 3-D and push its release back a week, to April 2. That will be the third 3-D movie to hit the market in a short span. DreamWorks Animation SKG Inc.'s "How to Train Your Dragon" comes out a week earlier, and The Walt Disney Co.'s "Alice in Wonderland" hits theaters March 5. And "Avatar" might still be playing in some places too. But a limited number of theaters can show these movies in 3-D, because not all theater owners have bought new digital projectors and undertaken other upgrades necessary to show movies in the format. About 3,900 to 4,000 3-D-ready screens are expected to be available in the U.S. and Canada by the end of March. Typically a movie in wide release might be shown on 3,000 to 10,000 screens in North America. In the past, a smaller number of 3-D-capable screens was adequate when one major film at a time was being released in 3-D in addition to 2-D. Each movie had a longer run, and moviegoers who wanted to see it in 3-D could pick a convenient time to go. With three out at once, each will get less exposure because some theaters with only one or two 3-D screens will have to choose which movies to show in 3-D. "One or all three are going to suffer in some way," said Patrick Corcoran, director of media and research for the National Association of Theatre Owners. "It makes it a much harder decision on exhibitors on what to keep or what to drop or what to add and probably should have been avoided."

Dengue fever causes severe flulike symptoms and is among the world's most pressing public health issues. There are 50 million to 100 million cases per year, and nearly 40 percent of the global population is at risk. The dengue virus is spread through the bite of infected female Aedes aegypti mosquitoes, and there is no vaccine or treatment. UCI researchers and colleagues from Oxitec Ltd. and the University of Oxford created the new breed. Flightless females are expected to die quickly in the wild, curtailing the number of mosquitoes and reducing - or even eliminating - dengue transmission. Males of the strain can fly but do not bite or convey disease. When genetically altered male mosquitoes mate with wild females and pass on their genes, females of the next generation are unable to fly. Scientists estimate that if released, the new breed could sustainably suppress the native mosquito population in six to nine months. The approach offers a safe, efficient alternative to harmful insecticides.
