The Future of Sustainable Farming Could Be Cold Plasma
Plasma is a fascinating medium. It’s considered the fourth state of matter—alongside solid, liquid and gas—and it’s everywhere. In fact, more than 99.9% of all matter in the universe is assumed to be in plasma form.
The Future of Sustainable Farming Could Be Cold Plasma
Plasma is a fascinating medium. It’s considered the fourth state of matter—alongside solid, liquid and gas—and it’s everywhere. In fact, more than 99.9% of all matter in the universe is assumed to be in plasma form.
You may be most familiar with plasma as the material inside those glowing novelty lamps found in museum gift shops, but it’s naturally found in the sun, lightning, and the northern lights. Research into plasma and how it intersects with various industries has been increasing, especially in the area of agriculture.
Cold plasma specifically is being tested as a way to speed up plant growth and make fertilizer that’s better for the environment. And it works: Lots of research has shown that exposure to cold plasma makes seeds germinate faster. While this sounds like a sci-fi concept, farmers have seen for decades that plants grown on the site of lightning strikes grow faster.
The strangest part? Scientists don’t know why this works, only that it does. Joining Ira to talk about cold plasma and its possible future in the agriculture world is Jose Lopez, professor of physics at Seton Hall University, based in South Orange, New Jersey. Lopez is also program manager for plasma physics at the National Science Foundation.
Why Are Teenagers So Sleep Deprived?
Teenagers have a reputation for being moody, making rash decisions, and maybe even being a bit lazy. Turns out, lack of sleep may be partly to blame for some of this stereotypical behavior.
Contrary to popular belief, teens actually need more sleep than adults—about 9 to 10 hours a night—to help support critical brain development. But American teens are getting less sleep than they ever have before due to a perfect storm of biology, increased homework, early school start-times, and technology. Over the past three decades, the average American teens’ sleep has shrunk to just 6.5 hours a night.
Ira talks with Heather Turgeon and Julie Wright, psychotherapists and sleep specialists. They’re co-authors of the new book, Generation Sleepless: Why Teens and Tweens Are Not Sleeping Enough and What We Can Do to Help Them.
The teen voices you heard during this segment were: Zion, Ro’Shell, LaRon, Aleathia, Zahriah, Trysten, Londyn, Jairus and Cix. All are 8th grade students at Manchester Academic Charter School, and recorded by SLB Radio at its Youth Media Center, in Pittsburgh Pennsylvania.
