How habitable is the Earth? Growing Skyscrapers: The Rise of Vertical Farms. Together the world’s 6.8 billion people use land equal in size to South America to grow food and raise livestock—an astounding agricultural footprint.

Growing Skyscrapers: The Rise of Vertical Farms

And demographers predict the planet will host 9.5 billion people by 2050. Because each of us requires a minimum of 1,500 calories a day, civilization will have to cultivate another Brazil’s worth of land—2.1 billion acres—if farming continues to be practiced as it is today. That much new, arable earth simply does not exist. To quote the great American humorist Mark Twain: “Buy land. Foreign subtitles improve speech perception. Jon's shtick on The Daily Show.

The White House’s war with Fox News. In 2008, half the people who watched the Fox News Channel were over sixty-three, which is the oldest demographic in the cable-news business, and, according to a poll, the majority of the ones who watched the most strident programs, such as Sean Hannity’s and Bill O’Reilly’s shows, were men.

All that chesty fulminating apparently functions as political Cialis. Fox News shows should probably carry a warning: Contact your doctor if you have rage lasting more than four hours. By effectively cornering the market on anti-Administration animus, Fox News has had a robust 2009 so far, and the recent decision by the White House to declare war on the channel is not likely to put a dent in the ratings. IBM Debuts Food Traceability iPhone App. Today at the IBM Information on Demand event, IBM will demo a new app that will bring the Internet of Things to the iPhone.

IBM Debuts Food Traceability iPhone App

The as yet unreleased iPhone app is called Breadcrumbs and it will give consumers access to information about grocery food items. The app will be able to scan barcodes and deliver a summary of the ingredients in a food item, along with when it was manufactured. That data is usually on the food label, but Breadcrumbs goes a step further - it can provide extra information such as product recall data. If a product has been recalled in the past, this app will tell the consumer all of the relevant details. Breadcrumbs is able to scan barcodes using the iPhone's camera. IBM told ReadWriteWeb that when 4G becomes common place in mobile phones, then apps such as Breadcrumbs will become more powerful and be readily used on-the-fly by consumers when grocery shopping.

Stereotypes can fuel teen misbehavior

Drugs. Caving into peer pressure. When parents expect their teenagers to conform to negative stereotypes, those teens are in fact more likely to do so, according to new research by Christy Buchanan, professor of psychology at Wake Forest University. "Parents who believe they are simply being realistic might actually contribute to a self-fulfilling prophecy," says Buchanan, who studies adolescent development and behavior. "Negative expectations on the part of both parents and children predict more negative behaviors later on. " In her study, published in the Journal of Research on Adolescence, Buchanan found that adolescents whose mothers expected them to take more risks and be more rebellious reported higher levels of risk-taking behavior than their peers one year later.

"Higher expectations for risk-taking and rebelliousness predict higher levels of problem behavior, even controlling for many other predictors of such behavior," Buchanan says.

The concept of amenable mortality was developed in the 1970s to assess the quality and performance of health systems and to track changes over time. U.S. Between 1997–98 and 2002–03, amenable mortality fell by an average of 16 percent in all countries except the U.S., where the decline was only 4 percent. The largest reductions in amenable mortality were seen in countries with the highest initial levels, including Portugal, Finland, Ireland, and the U.K, but also in some higher-performing countries, like Australia and Italy.
