Vertical 'Pinkhouses:' The Future Of Urban Farming?
Architects have come up with spectacular concepts for vertical farms that would grow crops in city skyscrapers. But many horticulturists think the future of vertical farming isn't in skyscrapers, but rather in large, indoor warehouses lit up magenta by superefficient LEDs.
Storm Chasers In It For The Thrill, Chance To Warn Others
Melissa Block talks with Chris McBee, a storm chaser and native Oklahoman who shot video of Monday's tornado, as it tore through the area around Oklahoma City. McBee and his companions phoned in the funnel cloud's location to the National Weather Service moments before debris — splintered wood and insulation — came whipping through the air.
'Nanogardens' Sprout Up On The Surface Of A Penny
Engineers have figured out a way to get crystals to form rose and tulip sculptures, each smaller than a strand of hair. The gardens sprout up on a penny dipped in a salt solution. The technique is similar to 3-D printing and could one day be used to make any complex shape.

Measuring The Power Of Deadly Tornadoes
Tornado strength is currently measured on what is called the Enhanced Fujita Scale, which gives the tornado a rating from 0 to 5 based on estimated wind speeds and the severity of the damage.
The Little Metronome That Wouldn't
Take a metronome. Then take another. Then another. Set them ticking at different times. Look. Lift. (That's the key part.) Watch. Then Laugh. Because you will be dumbfounded.
Can A Piece Of Hair Reveal How Much Coke Or Pepsi You Drink?
People are notorious for under-reporting what they consume — they lie, forget or just guess wrong. For researchers who want to know how much soda we're drinking, a high-tech analysis technique could help.
If Your Shrink Is A Bot, How Do You Respond?
A computer-simulated woman named Ellie is designed to talk to people who are struggling emotionally and take their measure — 30 times per second. Researchers hope their technology, which reads a person's body language and inflections, will yield diagnostic clues for clinical therapists.

Bans Of Same-Sex Marriage Can Take A Psychological Toll
When several states passed laws banning same-sex marriages, researchers found that the mental health of gay residents seemed to suffer.

The Unsuccessful Quest For A Universal Language
Within science circles, trying to come up with a new universal language was a trendy past-time in the 17th Century. Even the man who discovered gravity, Sir Isaac Newton, took a stab at it. Arika Okrent, editor-at-large at TheWeek.com, talks about its failure to catch on with Weekends on All Things Considered host Jacki Lyden.
David Foster Wallace Tells Us About Freedom
What do you get when you get a college diploma? To hear David Foster Wallace tell it, you get a muscle that will help you forever after — in shopping lines, overcrowded parking lots, in traffic jams. This muscle, he says, frees you when the world gets painfully dull.

Not Your Grandpa's RV: This Roving Lab Tracks Air Pollution
Atmospheric scientist Ira Leifer installed special air sensors on a camper, then drove from Florida to California, measuring methane levels all along the way. More than 6,000 readings later, he found some noticeable spikes, especially around petrochemical plants and urban areas like Los Angeles.
Scientists Agree On Climate Change, Why Doesn't The Public?
A new study confirms that the vast majority of scientists who research the climate accept that the planet is warming and human beings are largely responsible. Yet a large slice of the American public believes that scientists are deeply split about global warming.
Resetting the Theory of Time
Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists--and he says time is key to understanding the evolution of the universe.
Researchers Report Cloning Advance For Producing Stem Cells
Scientists reported this week in the journal Cell that they had used somatic cell nuclear transfer techniques to create a source of embryonic stem cells from the skin cells of a patient. George Daley, director of the stem cell transplantation program at Boston Children's Hospital, and Josephine Johnston of the Hastings Center discuss the research.
