You’re tired and you need an energy boost, but you don’t want the jitters from caffeine. What to do? In this week’s video, we give you some chemistry-backed tips — one of which involves cats — to boost your productivity and stay awake without refilling the coffee cup.
Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in Star Trek? In a special bonus episode of Reactions, we celebrate the International Year of Light by exploring the science behind light, sight and invisibility. Though we can’t make ourselves invisible yet, some promising research may light the way – or rather, bend the light away.
This episode of Reactions was produced in collaboration with the journal ACS Photonics. For more information on ACS Photonics, please visit:http://pubs.acs.org/journal/apchd5. Additional information on the International Year of Light can be found at: http://www.light2015.org.
Blue jeans are among the most popular clothing items in the entire world. But how did Levi Strauss get his “workwear,” as he called it, so blue? Through chemistry, of course. This week, we look at the chemistry of everyone’s favorite pair of pants.
How Much Water Can Kill You? – Reactions
You may have heard of deadly poisons like arsenic, cyanide and even the devilishly hard to detect polonium 210. But did you know even drinking water could kill you? We had Deborah Blum, Ph.D., author of the totally awesome book “The Poisoners Handbook,” explain how H2O can be deadly in the right dose.
Throughout the history of science, many major discoveries came accidentally. Sometimes they came from recognizing potential in an unexpected product or waste. Other times, discovery came out of pure desperation from a seemingly dead-end experiment. Here are some of those happy accidents that ended up changing the world.
This week Reactions makes first contact with the kerbalnauts! Through the fun of Kerbal Space Program, we examine the chemistry of rockets. Featuring Doane College Postdoctoral Fellow Raychelle Burks, Ph.D., we look at solid and liquid propellants and the “ride-able explosion” that is a rocket launch.
Acetaminophen, the active ingredient in Tylenol™, is one of the most popular pain relievers in the world, selling more than 27 billion doses in 2009 alone. It can reduce fevers, eliminate aches and pains and relieve cough and cold symptoms. But how does it work? The truth is, no one knows exactly. This week, Reactions examines the theories about the popular pill.
