Contributors Blanche Capel studied to be an interior designer before making the switch to biology. “There’s something about using your mind to understand the biology of who we are and how we work that makes me feel alive,” she says. In 1993, Capel started her own lab at Duke University studying sex–or, more specifically, the mechanisms that govern sex determination, a crucial developmental process. S

By Richard Gallagher Memo to Moneybags For $1 billion you can buy a mid-ranked soccer club…or a world class biotech cluster. A relatively small additional investment could end up with a big payout for the investor and the region. One of my fantasies is to own Celtic Football Club, a storied club based in Glasgow. So I can’t find it in me to outright criticize Sheikh Mansour bin Zayed Al Nahyan, who recently splashed out £8

Mail Thanks for an excellent article, and for creating The Scientist Video Awards competition.1 Homemade videos of scientists at work may be the best way to show the general public how science works, and make it relevant to their daily lives. Hopefully this article and the video competition will encourage more scientists to make videos about their work, and other professionals to develop resources and tools to make it easy for th

Stine’s transportation and vision for his biotechnology lab are straight out of the 1970s, when Genentech started in a warehouse, and Bill Gates and Paul Allen created Microsoft on a shoestring. Now, Stine is trying to do the same with North Coast Biologics. Mos

By Randy Olson Tell Me A Story of Science Want to generate interest in your research? Here’s how. “Heard any good talks?” That’s what you hear in the lobby of science meetings. The standard reply is, “I heard a great talk this afternoon—the speaker told a really neat story about ...” And there you have it. He or she told a good story. You want to know how to interest the public in your

By Steven Wiley Collaborations: Challenging, but Key Like any relationship, collaborations take energy, but nothing is better for your research. I learned about the difficulty in starting a collaboration when I began searching for one early in my career. Collaborations are becoming increasingly important in biology because of the need to apply multiple technologies to tackle the most complex current problems. The U.S. National Institutes

Even the seemingly simplest mammalian behaviors, such as grooming one’s offspring, involve a complex series of tiny movements that may be invisible to the human eye. But in studying those behaviors, how to break them down into reliable, measurable components? “All of these advances in technology give us data that [weren’t] available

By Ralf Dahm Nuclear Degradation in the Lens, circa 1897–1899 The developing lens (progressing left to right in the top line, then left to right in the bottom line) invaginates from the surface and pinches off as a hollow vesicle. The remaining cells then elongate to fill the vesicle and form a solid lens. Finally, the cells in the center of the lens degrade their nuclei and other organelles.
