...debate about the use of embryonic stem cells to grow replacement tissue (brain, liver, etc.) is about to get much more complex now that scientists have turned stem cells from mouse embryos into viable eggs. The report in Science set researchers' imaginations ablaze. Could this technique provide an endless supply of human eggs? And since scientists turned cells from both female and male mice into eggs, could it overturn traditional notions of parenthood? Could males make egg cells? Could gay couples produce genetic offspring? So far, the research holds promise only for gay mice...
...years, top climbers from around the world converged on Everest's slopes to attempt their own groundbreaking firsts. In 1978, Reinhold Messner's ascent without bottled oxygen defied the conventional wisdom that time spent without artificial oxygen above 7,900 meters?in the "death zone"?would cause irreparable brain damage. In 2000, Babu Chiri Sherpa?the most famous Sherpa?climbed from base camp to the top of Everest in just under 16 hours...
...also worried about how I would function above 7,900 meters, where the brain grows foggy and just taking a step requires monumental effort. I feared that not being able to think, along with not being able to see, would be an overwhelmingly bad combination. However, extreme altitude slowed down my team, so I actually had more time to plant my axe and kick solid steps in the steep snow. On the Hillary Step, I finally felt in my element. Similar to Hillary's own description, I wedged myself in a crack, my gloved hands scanning for holds...

...current review of the undergraduate curriculum is the perfect time to fix this problem. The University should require that students take a class that deals exclusively with the areas of our civilization’s greatest ignorance in either science, the humanities or the social sciences. How does the brain work? What is the ultimate fate of the universe? Why do economic theories fail so often? Did Homer actually live, and does that even matter? Although these questions will likely not be solved for many years, if ever, they can serve as inspiration. They can define the broad outlines...
