The Apple Watch is making quite a splash with its launch Friday, but most of us have never thought about this new gadget, the "smart watch." Is it a luxury item, or is the smart watch destined to be the next great essential, something we don't know we'll need but will.

Veterinarian Lynn Steele grows switchgrass on his farm to feed his hundred head of cattle.  He favors the wild-growing grass over other commercial feeds because it’s cheap.

“Even when the price is high [for switchgrass], it’s 4, 5, 6 dollars a pound for seed,” Steele said. “Indian grass and Big Blue Stem 12 and 15 dollars a pound. You get quite a bit of investment there.”

Daniel Swann is exactly the type of person the National Security Agency would love to have working for it. The 22-year-old is a fourth-year concurrent bachelor's-master's student at Johns Hopkins University with a bright future in cybersecurity.

And growing up in Annapolis, Md., not far from the NSA's headquarters, Swann thought he might work at the agency, which intercepts phone calls, emails and other so-called "signals intelligence" from U.S. adversaries.

Under The Microscope: Frank Booth and the 'Exercise Apex.'

MU Exercise Physiology Professor Frank Booth doesn’t just talk the talk on exercise. He runs the run. His regiment, when it allows, is to jump on treadmill in his office — yes, in his office — twice a day for high-intensity interval training.   

Booth also regularly runs the 1.3-mile route from his home to his office, using his car only for big errands like trips to the grocery store.

And sometimes, his dog –  a lab-boxer mix named Run — yes, Run — comes along for the jog.

But Booth’s hobby is indiscernible from his work life. His main goal through his research is to inform people of the true danger of not getting enough exercise. And in the early 2000's he coined a term in for this very risk: sedentary death syndrome.  


As you’ve probably heard, a well-respected group of World Health Organization scientists said glyphosate, the active ingredient in Monsanto’s wildly popular Roundup herbicide and its generic cousins, is probably capable of causing cancer in humans.

People who struggle with suicidal thoughts will often reach out to friends and family first. But when our social circle lives online these days, the biggest social media networks grapple with how to intervene and with getting users the right kind of help.

Facebook is the latest social media network to roll out support resources for suicide prevention. The company is now trying to combat suicide by doing what it does best — connecting friends.

  Throughout 2015, the City of Columbia has made strident efforts to overhaul its trash services. While most of the focus has been put on the potential “what if’s” of switching from the city’s current curbside pick-up system to an automated roll-cart service, there has also been discussion about how to raise the city’s diversion rate, or the amount of trash that the city throws away that doesn’t end up in landfills. However, some citizens are still asking for more  — to move to a more seamless single-stream recycling system like they have in Saint Louis.

MU will install a dual-polarization Doppler radar as part of the five-year Missouri Transect project, which is funded by a $20 million grant from the National Science Foundation. The new radar will improve the precision of weather forecasts for mid-Missouri residents.

John Walker, MU curators’ professor of biological sciences, is the principal investigator of the project. He said the project’s original goal was to answer the question of how climate change affects plant productivity, both in native ecosystems and agricultural systems. Walker said the dual-polarization radar will help answer this question by providing more complete data, closer to the ground. Unlike traditional Doppler radars, dual-polarization scans vertically as well as horizontally, proving a three-dimensional image of weather systems. 

George Dante fell in love with taxidermy as a young child. His parents took him to the American Museum of Natural History in New York City, and he couldn't tear his eyes away from the dioramas in the Hall of African Mammals.

Pippa Hull sits on her mother’s lap across the kitchen table in their Parkville home. She is an outgoing and talkative seven-year-old girl, who just happens to have a rare and severe form of epilepsy called Lennox-Gastaut syndrome. Pippa’s mother, Megan, said this form of epilepsy is characterized by its lack of response to treatments.

Hull said they have tried different medications, they have had a VNS or Vagus Nerve Stimulation device implanted in Pippa’s chest, and they have even tried a special diet to try and reduce the number of seizures Pippa experiences.

Last week, the Federal Aviation Administration proposed its long-awaited rules for commercial drone flights in US airspace. If approved, they could open up the sky in the St. Louis area for a variety of unmanned aircraft.

This week, the photo editing software Adobe Photoshop turned 25 years old. The program is an industry juggernaut — so famous that the word "Photoshop" has come to be synonymous with image manipulation.

But when the software started, says co-creator Thomas Knoll, it was a personal project. He and his brother John started working on the program in the late 1980s.

On this week's edition of Under the Microscope, we'll be taking a look at the new drone flight regulations proposed by  The Federal Aviation Administration. While the rules may limit some commercial potential for drones to be used in package delivery and pipeline inspection, many other industries are finding the new technology to be extremely lucrative, especially agricultural ones.  Harvest Public Media's Luke Runyon explores how the potential guidelines could "usher in a new era of farm machinery."

A highly anticipated batch of federal laws governing the use of drones could change the regulatory landscape and lead to an explosion in drone use by farmers.

Farmers see drones as a way to get a birds-eye view of their fields to find problem patches with crops. That information can allow farmers to be more precise with fertilizers and pesticides and, ultimately, save them money. But getting them in the sky without running afoul of federal regulation is proving to be a challenge.


Restaurant servers are three times more likely to receive below-poverty-line pay than the rest of the U.S. workforce. Yet in a world where shoppers fret over cage-free eggs and organic vegetables, how many are also asking how much their favorite restaurant pays its staff?

A couple of listeners wrote to Morning Edition on Thursday with the same idea.

"Did anyone notice that shortly after reporting on the difficulty of tracking airliners in flight, you aired a story about a gentleman in West Virginia who was able to work with Google to track fishing boats in real time?" wrote Paul Douglas from Simsbury, Conn.

Landscape diversity in Missouri has changed since its settlement in the 18th century. Where there was once prairies, forests and savannahs, in many cases there are now towns, cities and farms.

The Missouri Department of Conservation is working to remedy this problem by restoring prairies to “pre-settlement standards.” These standards include no non-native plant species and plants from within a 50 mile radius of the prairie.


On a mountaintop in Chile, excavators have just started work on a construction site. It will soon be home to a powerful new telescope that will have a good shot at finding the mysterious Planet X, if it exists.

"Planet X is kind of a catchall name given to any speculation about an unseen companion orbiting the sun," says Kevin Luhman, an astronomer at Penn State University.

Waze, the popular navigation app boasting more than 50 million users worldwide, has a new critic: police officers. Over the past few weeks, law enforcement officials have been urging the app and its owner, Google, to disable a feature that allows users to report when they've spotted a police officer, in real time, for all other Waze users to see.

Sergio Kopelev, a reserve sheriff in Orange County, Calif., is one of the law enforcement officials behind the push to remove Waze's police tracker. He says he first discovered the feature through his family.

The Bulletin of the Atomic Scientists (BAS) has moved the Doomsday Clock two minutes closer to disaster. It now stands at three minutes before midnight.

The BAS was created in 1945 by the scientists who had participated in the Manhattan Project, developing the atomic bomb. They came up with the Doomsday Clock in 1947, after the Hiroshima and Nagasaki bombings, to alert the public to the dangers of nuclear proliferation. Midnight represents a global catastrophe.

Humans have been growing hemp for centuries. Hemp-based foods have taken off recently. So have lotions and soaps that use hemp oil. 

There’s evidence that different compounds in cannabis could be used as medicine and hope that its chemical compounds could hold keys to treatments for Parkinson’s disease and childhood epilepsy. 

 


Lonesome George was a celebrity tortoise. Millions of humans made the pilgrimage to see him while he lived, and his death was international news.

Missouri will get more than $280,000 from T-Mobile following claims that the company was unfairly charging customers for third-party text message subscriptions.

NPR has confirmed from U.S. intelligence officials that North Korea was centrally involved with the recent attacks against Sony Pictures. And the company says it is pulling its comedy film The Interview from the box office. It was supposed to debut on Christmas. These are major developments in what we may now call cyberwarfare.

The latest word from scientists studying the Arctic is that the polar region is warming twice as fast as the average rise on the rest of the planet. And researchers say the trend isn't letting up. That's the latest from the 2014 Arctic Report Card — a compilation of recent research from more than 60 scientists in 13 countries. The report was released Wednesday by the National Oceanic and Atmospheric Administration.

NASA's unmanned Orion spacecraft has successfully splashed down about 400 miles west of La Paz, Mexico, in the Pacific Ocean after a liftoff, two orbits and re-entry that lasted just under 4 1/2 hours.

Orion, which could one day take astronauts to Mars, made a "bull's-eye splashdown" at 11:29 a.m. ET, mission control said, after the spacecraft endured a searing 4,000-degree Fahrenheit re-entry and was carried to the ocean surface under four giant red-and-white parachutes.
