||CleanThe science of tall trees||Sometimes science is focused on really big questions: where did life come from? How did the universe begin? But sometimes, the focus is much smaller. Sometimes, researchers set out to answer a simple question, one that many people have perhaps [...]||14/1/13||Gratis||Ver en iTunes|
||Planets, planets everywhere||You don’t have to be very old to remember a time when we didn’t know if there were any planets anywhere else in the universe beyond those in our own solar system. Oh, sure, scientists and science fiction writers had long assumed these [...]||7/1/13||Gratis||Ver en iTunes|
||CleanCircadian desynchrony and the blue light special||We’re coming up on the shortest day of the year in the northern hemisphere: at the latitude I live at, in Regina, Saskatchewan, that means that today the sun rose at 8:49 a.m. and will set at 4:54 p.m. We’ll lose a few more minutes yet before [...]||10/12/12||Gratis||Ver en iTunes|
||CleanThe case for coffee consumption||I first wrote about coffee in a science column back in the dawn of time, so long ago that it began, “Let’s get one thing straight. I don’t drink coffee…” Since as I type this I am on my second…or maybe third… good-sized cup (oh, all [...]||3/12/12||Gratis||Ver en iTunes|

You wouldn’t? [...]||26/11/12||Gratis||Ver en iTunes|
||Throwing like a girl||There’s a scene in Huckleberry Finn where Huck is attempting to pass himself off as a girl, but is betrayed, in part, by the way he throws a lump of lead at a rat: “And when you throw at a rat or anything, hitch yourself up a tiptoe and fetch [...]||19/9/12||Gratis||Ver en iTunes|
||CleanEdison’s Battery||Thomas Edison gave us many wonderful inventions, mainstays of 20th century life. However, since he died in 1931, you might be forgiven for asking, “What has he done for us lately?” Him personally, not so much, what with being dead and all: but [...]||12/7/12||Gratis||Ver en iTunes|
||CleanNo need for gas-price conspiracy theories||There’s a public perception that somebody must be pulling the strings on gas prices, that somewhere in some shadowy secret lair mustache-twirling oilmen are gleefully conspiring to raise prices across the board just in time for summer holidays.

||CleanA handheld MRI?||Magnetic Resonance Machines are massive (and massively expensive) devices, large enough to slide an entire person into on a table. But the technology that makes them so valuable in diagnosing cancer and other diseases doesn’t have to be either [...]||28/6/12||Gratis||Ver en iTunes|
||Where the germs are||Ah, vacation time! Relaxing by the beach or in the mountains, retiring at night to a filthy hotel room, crawling with germs… Wait, what? Okay, that might be a slight overstatement of the hygienic challenges of hotel rooms, but the fact remains [...]||20/6/12||Gratis||Ver en iTunes|
