Are We Alone Back
 
 That's Containment!

ENCORE We all crave power: to run laptops, charge cell phones, and play Angry Birds. But if generating energy is easy, storing it is not. Remember when your computer conked out during that cross-country flight? Why can’t someone build a better battery?

Discover why battery design is stuck in the 1800s, and why updating it is key to future green transportation (not to mention more juice for your smartphone). Also, how to build a new type of solar cell that can turn sunlight directly into fuel at the pump.

Plus, force fields, fat cells and other storage systems. And: Shock lobster! Energy from crustaceans?

Guests:

  • Dan Lankford – Former CEO of three battery technology companies, and a managing director at Wavepoint Ventures
  • Jackie Stephens – Biochemist at Louisiana State University
  • Kevin MacVittie – Graduate student of chemistry, Clarkson University, New York
  • Nate Lewis – Chemist, California Institute of Technology
  • Alex Filippenko – Astronomer, University of California, Berkeley
  • Peter Williams – Physicist, San Francisco Bay Area

 Since Sliced Bread

Happy Birthday, World Wide Web! The 25-year-old Web, along with the Internet and the personal computer, are among mankind’s greatest inventions. But back then, who knew?

A techno-writer reminisces about the early days of the WWW and says he didn’t think it would ever catch on.

Also, meet an inventor who claims his innovation will leave your laptop in the dust. Has quantum computing finally arrived?

Plus, why these inventions are not as transformative as other creative biggies of history: The plow. The printing press. And… the knot?

And, why scientific discoveries may beat out technology as the most revolutionary developments of all. A new result about the Big Bang may prove as important as germ theory and the double helix.

 Skeptic Check: Evolutionary Arms Race

It’s hard to imagine the twists and turns of evolution that gave rise to Homo Sapiens. After all, it required geologic time, and the existence of many long-gone species that were once close relatives. That may be one reason why – according to a recent poll – one-third of all Americans reject the theory of evolution. They prefer to believe that humans and other living organisms have existed in their current form since the beginning of time.

But if you’ve ever been sick, you’ve been the victim of evolution on a very observable time scale. Nasty viruses and bacteria take full advantage of evolutionary forces to adapt to new hosts. And they can do it quickly.

Discover how comparing the deadly 1918 flu virus with variants today may help us prevent the next pandemic. Also, while antibiotic resistance is threatening to become a major health crisis, better understanding of how bacteria evolve their defenses against our drugs may help us out.

And the geneticist who sequenced the Neanderthal genome says yes, our hirsute neighbors co-mingled with humans.

It’s Skeptic Check … but don’t take our word for it!

 Do the Math

ENCORE One plus one is two. But what’s the square root of 64, divided by 6 over 12?* Wait, don’t run for the hills! Math isn’t scary. It helps us describe and design our world, and can be easier to grasp than the straight edge of a protractor.

Discover how to walk through the city and number-crunch simultaneously using easy tips for estimating the number of bricks in a building or squirrels in the park. Plus, why our brains are wired for finger-counting … whether aliens would have calculators … and history’s most famous mathematical equations (after e=mc2).

*The answer is 16

 You Think; You're So Smart

Sure you have a big brain; it’s the hallmark of Homo sapiens. But that doesn’t mean that you’ve cornered the market on intelligence. Admittedly, it’s difficult to say, since the very definition of the term is elusive. Depending on what we mean by intelligence, a certain aquatic mammal is not as smart as we thought (hint: rhymes with “caulpin”) … and your rhododendron may be a photosynthesizing Einstein.

And what I.Q. means for A.I. We may be building our brilliant successors.

 We Heart Robots

ENCORE The machines are coming! Meet the prototypes of your future robot buddies and discover how you may come to love a hunk of hardware. From telerobots that are your mechanical avatars … to automated systems for the disabled … and artificial hands that can diffuse bombs.

Plus, the ethics of advanced robotics: should life-or-death decisions be automated?

And, a biologist uses robo-fish to understand evolution.

 Space for Everyone

Is space the place for you? With a hefty amount of moolah, a trip there and back can be all yours. But when the price comes down, traffic into space may make the L.A. freeway look like a back-country lane.

Space is more accessible than it once was, from the development of private commercial flights … to a radical new telescope that makes everyone an astronomer … to mining asteroids for their metals and water to keep humanity humming for a long time.

Plus, move over Russia and America: Why the next words you hear from space may be in Mandarin.

Guests:

  • Leonard David – Space journalist, writer for SPACE.com
  • Mario Juric – Astronomer working on data processing for the LSST – the Large Synoptic Survey Telescope
  • John Lewis – Chemist, professor emeritus of planetary sciences, University of Arizona, chief scientist, Deep Space Industries
  • Philip Lubin – Professor of physics, University of California, Santa Barbara
  • James Oberg – Retired NASA rocket scientist, space historian, and a self-described space nut

 Before the Big Bang

ENCORE It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that! What happened before the Big Bang? It’s the ultimate prequel.

Plus – the Big Bang as scientific story: nail biter or snoozer?

 Skeptic Check: Paleo Diet

What’s for dinner? Meat, acorns, tubers, and fruit. Followers of the Paleo diet say we should eat what our ancestors ate 10,000 years ago, when our genes were perfectly in synch with the environment.

We investigate the reasoning behind going paleo with the movement’s pioneer, as well as with an evolutionary biologist. Is it true that our genes haven’t changed much since our hunter-gatherer days?

Plus, a surprising dental discovery is nothing for cavemen to smile about.

And another fad diet that has a historical root: the monastic tradition of 5:2 – five days of eating and two days of fasting.

It’s our monthly look at critical thinking, Skeptic Check … but don’t take our word for it.
