Disease has a negative connotation in evolutionary thought. But, in some instances, a selective advantage may be conferred by disease processes. On this program, Dr. Sharon Moalem discussed the survival of the sickest.

A huge potential for our energy needs lies at the bottom of the ocean in the form of methane hydrates. But what happens when the ocean burps and large amounts of natural gas are liberated into the atmosphere? On this program, MBARI scientist Charles Paull discusses how these greenhouse gases could be abruptly released.

Do I have a chance with them? Should I drink the milk at the back of the refrigerator? Solving everyday problems like these can be especially problematic without the proper tools. Luckily, math can provide the answer. On this program, Garth Sundem discussed mathematical solutions to everyday problems.

Size matters... especially in biology. But the dimensions of living organisms are often disregarded, while it is arguably essential to their study. On this program, Prof. John Tyler Bonner discussed why size matters in biology.

Altruistic behavior is seemingly at odds with the classic notion of evolution. How can altruism be reconciled with the survival of the fittest? On this program, Prof. Lee Alan Dugatkin discussed the altruism equation.

Billions and billions of years ago, stars in the universe created elements that scattered throughout the galaxies. Until recently, these dust particles from the early universe were frozen in comets. On this program, Dr. Andrew Westphal discussed the StarDust project, the challenges in collecting comet dust and the surprising discoveries made from these samples.

Tracking the evolutionary changes that give rise to new species has become more refined with the advent of molecular biological tools. Changes in DNA sequences over time can now be measured across species to provide a genetic picture of evolution in action. On this program, Prof. Sean B. Carroll discussed these new findings.

For many technophiles, Christmas comes a couple weeks after the fact. At Macworld 2007, we saw a glimpe of what future telephony will look like, but at the same time, developers have products ready to go. On this program, Jon Philips from MacLife magazine discussed current trends in computing. Also, Kevin Ford talked about advanced telephone systems.

Let it snow, let it snow, let it snow. But, what are the physical processes that underlie the formation of snowflakes, and how can this process be reproduced? On this program, Prof. Kenneth Libbrecht from Caltech discussed the physics of snowflakes.

Most of us know earthquakes by their groundbreaking nature, but what has intrigued seismologists recently are silent earthquakes. On this program, Prof. Paul Segall discussed the significance of these imperceptible ground movements. In addition, Chuck McMinn discussed combined heat and power systems at Vineyard29.
