$500 Million to Reduce Childhood Obesity in USA

$500-Million Commitment to Reverse Childhood Obesity in U.S.:

The Robert Wood Johnson Foundation (RWJF) today announced it will commit at least $500 million over the next five years to tackle one of the most urgent public health threats facing our nation: childhood obesity. This is the largest commitment by any foundation to this issue. The Foundation’s goal is to reverse the epidemic of childhood obesity in the United States by 2015.

During the past four decades, obesity rates have soared among all age groups, more than quadrupling among children ages 6 to 11. Today, more than 33 percent of children and adolescents—approximately 25 million kids—are overweight or obese.
…
In addition to the toll on our nation’s health, obesity also poses a tremendous financial threat to our economy and our health care system. It’s estimated that the obesity epidemic costs our nation $117 billion per year in direct health care costs and lost productivity. Childhood obesity alone carries a huge price tag-up to $14 billion per year in direct health care costs to treat kids.
…
The Foundation will focus on improving access to affordable healthy foods and opportunities for safe physical activity in schools and communities.

Cats Control Rats … With Parasites

What, then, could attract rats to cat pee? None other than toxoplasma gondii, a parasite carried by cats. If a rat is infected by t. gondii, cat urine doesn’t seem so bad anymore; it’s even kind of attractive. Even more impressively, Stanford University researchers have found that the rats otherwise behave normally, with all their usual fears intact. The response is so specific that cats and t. gondii seem almost like a single organism — which, in a sense, they are.

Drug-resistant Flu Virus

Drug-resistant flu virus emerges in untreated patients:

The emergence of drug-resistant influenza was documented in a study of Japanese patients. It is a clear early warning that flu viruses may be beginning to outwit what are now highly effective drugs, says Yoshihiro Kawaoka, a University of Wisconsin-Madison virologist and the senior author of the new JAMA study.

“There is urgent need to develop new kinds of antivirals,” says Kawaoka, an internationally recognized authority on influenza. “This is the first report that drug-resistant influenza B virus may be transmitting in the community.”

Fellowship Winners

Several fellowships and scholarships have announced winners for this year:

NSF Graduate Research Fellowships
Department of Defense (NDSEG) Fellowships – no online list of winners yet
Marshall Scholarships (link broken, so removed)
Google Anita Borg Memorial Scholarship – blog announcement

As I have mentioned before I work for ASEE (which manages the NSF and NDSEG fellowships): this blog is my personal blog and is not associated with ASEE.

Ranking Universities Worldwide

The Webometrics Ranking of World Universities provides another estimate of the top universities. The methodology is far ideal however I still find it interesting. The various attempts to rank schools can provide a general idea of impact of various institutions (though the measures are fairly crude). Still a sensible picture (especially at the country level) can emerge. And the various rankings should be a able to track shifts in the most influential institutions and relative country strength over time. How quickly those rankings track changes will vary depending on the measures used. I would imagine most will lag the “real” changes as it is easy to imagine many measures that would lag. Still, as I have said before, I expect the USA will lose in relative ranking compared to China, India, Japan, Singapore, Mexico…

The ranking methodology used here weighed rankings in: Jiao Tong academic rankings, Essential Science Indicators, Google Scholar, Alexa (a measure of web site visits to universities) and The Times Higher World University Rankings.

Country representation of the top universities (number of top schools in each country):

location	Webometrics Top 100	Jiao Tong Top 101	% of World Population	% of World GDP*
USA	53	54	4.6%	30.4%
Germany	10	5	1.3	6.3
Canada	8	4	0.5	2.5
United Kingdom	6	10	0.9	5.0
Australia	3	2	0.3	1.6
Japan	1	6	2.0	10.3
The rest of Europe	16	13
Brazil	1	0	2.8	1.8
Mexico	1	0	1.6	1.7
Israel	0	1	0.1	0.3

Lead the Way – Cleveland

Project Lead the Way introduces students to engineering (site broke the link so I removed it – poor usability):

Project Lead The Way offers hands-on curriculum to allow students a taste of the creativity, variety, teamwork and possibilities engineering fields are offering. The course teaches students the key elements and skills of engineering and technology-based careers.
…
“In the five years we’ve had this program, we went from 20 to over 300 students,” he said. “Our goal is gender equity. We want to see more diversity. We started out with two females five years ago. Now we’re about 28 percent female. We’re seeing more African Americans and more Asians coming in.”

Micro-Wind Turbines for Home Use

Hong Kong Inventors Unveil New Micro-Wind Turbines Suitable for City Dwellers

“Let’s say if you have good conditions, five, six meters [of wind] per second, if you are a family with one kid you need most probably three, four square meters of that then you can most probably cover at least 60, 70 percent of your [energy] needs.” The technology can also help power bigger buildings. Administrators at Hong Kong’s Sea School, a secondary school offering basic seaman training, will install the new micro wind-turbines on its roof in April.

Gambarota says his biggest dream is to see his invention being used in developing countries. He says energy generated by micro wind turbines can be used to pump water, for example, saving women and girls from having to walk for miles to rivers and lakes to fetch it.

Information from Motorwave. Very cool idea though still early (they are meant only to provide electricity for immediate use at this time – no way to sell excess power to the grid or battery backup yet).

Big Atlantic Sharks Disappearing, Study Warns

Tiger Shark

Big Atlantic sharks disappearing, study warns (phb broke link so I removed it):

Humans, mainly those in countries with a craving for shark-fin soup, have devoured so many of the oceans’ top predators that it has rattled the length of the marine food chain, according to a study to be published today in the prestigious journal Science. While previous studies have calculated declines by half or more, this one argues that seven of the largest sharks along the Atlantic Coast have all but vanished because of overfishing — down as much as 99 percent for bull, dusky and smooth hammerheads over the last 35 years.
…
The study’s premise: As larger sharks disappeared, smaller ones and rays, both often prey, exploded over the same period. One in particular, the cownose ray, perpetuated to the point that by 2004 it gulped down much of the scallop population in Chesapeake Bay. ”I think that’s just the tip of an iceberg,” Fordham said. “There are so many connections we don’t understand. Sharks keep the oceans in balance.”

Yale Cultivates Young Scientists

Yale Science and Engineering Association (YSEA), Outreach programs cultivate young scientists:

Since 1989, YSEA has funded high-school science fair awards all over the world; in 2006, 241 outstanding high school students were awarded YSEA medals. By getting the Yale name into the public consciousness, YSEA hopes to draw high school applicants who intend to major in the sciences.
…
For New Haven high school students, the New Haven Science Fair Program pairs them up with Yale graduate students for one-on-one mentorships. The students select a field that interests them, then develop an in-depth science fair project that teaches them about the scientific process. It’s an enjoyable introduction to the world of science research, and in early March, the students got the opportunity to show off what they’d learned in the yearly science fair, held in Commons.
