As fat people have an abundance of fat tissue, the natural assumption is that fat people have more fat cells, or ‘adipocytes’. That’s only part of the story - it turns out that overweight and obese people not only have a surplus of fat cells, they have larger ones too.
…
During adulthood, about 8% of fat cells die every year only to be replaced by new ones. As a result, adults have a constant number of fat cells, even those who lose masses of weight. Instead, it’s changes in the volume of fat cells that causes body weight to rise and fall.

we couldn’t have a clearer indication of the importance of childhood as a window for preventing obesity and the chronic diseases affected by it - cancer, heart disease, diabetes and more.

The message is especially stark following the recent Foresight report, which estimated that if current trends are left unchecked, by 2050 a quarter of all UK children under the age of 16 will be obese. The knowledge that their fat cell count will then be set for life makes the cost of inaction even higher. Fortunately, it seems that the UK Government is taking appropriate steps and recently pledged over a third of a billion pounds on a concerted strategy to tackle childhood obesity.

For the 2007 awards, 99 middle school and high school math and science teachers are receiving this recognition. In the citation from the president, winners are commended “for embodying excellence in teaching, for devotion to the learning needs of the students, and for upholding the high standards that exemplify American education at its finest.”

Each winner receives a $10,000 award from NSF, as well as a trip for two to Washington, D.C., for a week of celebratory events and professional development activities.

Among the activities during that week are a day with scientists and science educators at NSF; meetings with members of Congress and federal agency leadership; and a reception and dinner at the U.S. Department of State featuring guest speaker Dorothy Metcalf-Lindenburger, a NASA Astronaut-Mission Specialist.

“Believe it or not, nobody had looked before,” says Suttle. “On average, there are 50 million viruses per milliliter in seawater. The question is, What the heck they’re doing there?” Microbiologists then documented similar, and even higher, concentrations of phages in soil samples. This led to estimates of 10³¹ bacteriophages worldwide, a staggeringly large number that many scientists initially dismissed. “We can’t wrap our brains around it,” says Pedulla. “If phages were the size of a beetle, they would cover the Earth and be many miles deep.”
…
According to estimates put forth by Suttle, phages destroy up to 40 percent of the bacteria in Earth’s oceans each day.
…
The students collected soil from barnyards, gardens, and even the monkey pit at the Bronx Zoo. The scientists then taught the students how to isolate a bacteriophage from the soil by growing the viruses in Mycobacterium smegmatis, a harmless bacterial relative of the microbe that causes tuberculosis. “We guarantee them that the bacteriophage they find will never have been discovered before. We know that because the diversity is so high, and we’ve never isolated the same bacteriophage twice,” says Hatfull.

In the April 18 Cell, Hatfull and his professional and teenage collaborators describe the genomes of 10 soil-dwelling bacteriophages that they had isolated. Of the more than 1,600 genes that the team identified, about half are novel, that is, they don’t match any previously described genes in any other organism.

The third poster shows the threats that our turtles are facing — a turtle is trapped in a fisherman’s net, a turtle is consuming a plastic bag, which it mistakes as a jellyfish, and there are rubbish on the sea floor.

a 4-month scholarship, and involves professional training in the conservation of turtles (including sea turtles, freshwater turtles and tortoises, I presume). The flow of the program has yet to be finalized but according to the Director of the Program, we (the Laotian student and I) would be spending one month visiting turtle scientists and turtle research centers in New Jersey, Tennessee, Florida and maybe California.

And the remaining 3 months would be spent at the Wetlands Institute at Stone Harbor, New Jersey. The training will be conducted at the Wetlands Institute, together with other local participants.

In a five year study of more than 2,000 youngsters, those who skipped breakfast weighed on average 5lbs (2.3kg) more than those who ate first thing. This was despite the fact that the breakfast-eaters consumed more calories in the course of the day. But the study in Pediatrics found they were likely to be much more active.

The University of Minnesota research adds weight to a growing body of evidence that those who eat breakfast - whether young or old - are leaner than those who do not.
…
“The real problem is the profusion of messages about obesity. We need to make clear that eating regular meals is vital - and that a proper breakfast is very important. “If you eat well first thing, you’ll feel brighter, you’ll have more get up and go - and that will mean you’ll expend more energy.”

Teenagers are not the only ones who may benefit from sitting down to a proper breakfast. In a study of nearly 7,000 middle-aged people in Norfolk, a team from Cambridge University found that those who ate the most in the morning put on the least amount of weight.

A team of eight British college students, calling themselves Fangs A Lot, have created the first false tooth for a cat and set up a business, Animal Solutions, to market false teeth for cats, dogs, and other animals. The group and its prototype false cat tooth have made it to the finals of the Ideas Igloo Roadshow, an invention contest for college students sponsored by Britain’s Make Your Mark Campaign and Microsoft, UK.

False teeth for cats may sound ridiculous, but they could be a solution to a serious problem for cats. Cats have notoriously bad dental problems. Cat owners seldom brush their cats’ teeth or scrape the surfaces of the teeth to remove plaque. By the time a cat is 3 or 4 years old, she may already have periodontal disease that can lead to tooth loss. Tooth loss may also come about as a result of tooth breakage, particularly in the canine teeth.

As educators statewide push for better science and math education, the popularity of an international robotics competition has grown drastically among Minnesota high schools. The FIRST Robotics competition, where high school students build complicated robots to push a ball along and do other tasks, has 54 Minnesota teams this year, up from just two in 2006.

Area educators attribute the growth to dramatic fundraising by Minnesota technology companies desperate to encourage future engineers and a statewide push to improve science and technology education. “It’s a long-term investment,” said Dr. Stephen Oesterle, senior vice president of medicine and technology for Medtronic, who pushed other companies to donate.
…
The competition started in New Hampshire in 1992. Now, it includes more than 1,500 teams from around the world. Founded by entrepreneur Dean Kamen, the inventor of the Segway, FIRST stands for “For Inspiration and Recognition of Science and Technology.”

When Shivani Sud was six years old, one of her immediate family members was diagnosed with a brain tumor. Inspired by the doctors who helped her loved one recover, Shivani set her sights on a career in medicine.

Fast forward to Intel STS 2008, where the 17-year-old senior from Durham, North Carolina, presented research focused on identifying stage II colon cancer patients at high risk for recurrence and the best therapeutic agents for treating their tumors. Whereas the standard method of characterizing tumors relies on visual information (such as size, degree
of metastasis, and microscopic structure), Shivani developed a “50-gene model” which uses gene expression to link multiple genetic events that characterize various tumor types to more accurately predict the recurrence of colon cancer. Additionally, Shivani’s model can be used to identify drugs that may be most effective in treating each patient.

More than 2,200 middle and high schools use engineering courses offered by Project Lead the Way, a Clifton Park, N.Y., nonprofit that receives industry support, up from just 12 when the initiative started in 1997. And Infinity Project, developed out of Southern Methodist University in Dallas, is now in 300 schools, up from 12 in 1999. The impact of these initiatives on the ranks of engineers remains to be seen.

Besides creating curricular approaches, groups are lobbying state governments to add engineering to their education standards.

Massachusetts included engineering content in its state science requirements for grades K-12 starting in 2001. New Hampshire began sprinkling engineering and technology concepts into its science curriculum starting last school year. New Jersey incorporated engineering concepts into its state education standards starting in 2004. And more states are following: Texas is working on creating standards for an engineering course that can be used to fulfill a high-school science credit.

Teaching through problem-solving storybooks that feature characters from around the globe “becomes a lot richer and is liberating for many kids and many teachers,” she says. The curriculum can cost as little as $40 — the price of a teacher’s binder, including lesson plans and one storybook. For about $6,000, a school could furnish materials, refills and a storybook for each student in every grade.

Mitch Lown and Dave Arndt teach technology education to students at Bangor High School and West Salem High School. A few of the courses they teach were once, years ago, called “shop class,” but the curriculum is far more advanced today. Not only are these not your father’s shop classes, they aren’t shop classes at all.

Computer programs, 3-D designs, architectural drawing, engineering, mass production and the design and marketing of products are only some of the areas local high school students are tackling in Lown and Arndt’s classes.
…
In their manufacturing classes, both Lown and Arndt give students a feel for what it’s like to set up a business and produce and sell a product. And they do make a profit. Lown’s students, for example, built and sold mounting kits for deer antlers and made a profit on the venture. Arndt said he always stays conscious of the world that students will face after graduation.

“I address every class as if it’s a job,” he said. “We’re not here to waste time because that’s not the way it’s going to be when they get in the job market. The biggest challenge for me is changing the attitudes of some students and instilling a work ethic. If they say they are going to do something, they need to follow through on that.”

Phun is without question the greatest computer toy in the history of the universe, if this had been around when I was a kid I would be a frickin genius by now. You don’t need things any more. It’s extremely easy to use. As a starter tip, turn gravity off when you’re attaching stuff to the background (right click after selecting “affix” tool).

Intel Microelectronics (Thailand) Ltd is sponsoring five young Thai students to participate in the 59th Intel International Science and Engineering Fair (Intel ISEF) in Atlanta, Georgia
…
Two of the individual entries are a musical instrument sound analysis and recognition system, which won the first prize in the computer science category, and was developed by Boonyarit Somrealvongkul, and a method of measuring a curved path’s radius with a modified car, which took first prize in the engineering category and was developed by Ronnapee Chaichaowarat.

The third project is a team entry, “New Plywood Products”, the first prize winner in the environmental science category, developed by Pheemadej Prasitwarawej, Tanavorakit Bangkeaw and Manapas Hararak, from Montfort College, Chiang Mai.

Over 1,500 of the brightest young scientists from around the world attend the fair every year, where they share ideas, showcase cutting-edge science projects and compete for more than $3 million (94.5 million baht) in awards and scholarships.

this blog offers deeper insights into education in China, India and the United States, and the challenge America faces. Now you can join a dialog about what governments, communities and families should and are doing to best prepare US students for satisfying careers in the 21st century.

The film follows two students from Carmel High School in Indianapolis, as well as two students from India and two from China. The premise is that they all have roughly 2 million minutes in high school to build their intellectual foundation and prepare for college and a career.

Twenty months in the making, “2 Million Minutes” highlights the pressures and priorities of these students and their families. Ultimately, it provides insight into the changing nature of competition in a technology-based global economy.

“As a high-tech entrepreneur and venture capitalist for the past 25 years,” Compton said,” I can tell you the people who have reaped the greatest economic rewards in the past two decades have been those with the most rigorous and thorough understanding of technology — and thus a solid foundation in math and science — and who have an ability to solve problems and possess entrepreneurial skill.”
