New technologies appear all the time. Right at this moment scientists are laboring away on the Herculean task of making an artificial cell, a challenge that for the first nine tenths of the 20th century many biologists would have dismissed as an impossibility. Just as important as new invention, though, is the translation of ingenuity into practice. This year's SCIENTIFIC AMERICAN 50 represents a testament to pragmatism. Many of the reports that have wowed the public on advances in nanotechnology or stems cells, to name just two, have taken a big step from graduate-level research toward becoming items for purchase at Wal-Mart or routine therapies at your local hospital.

A Korean researcher gained worldwide attention by achieving a 10-fold improvement in the number of stem cell lines derived from cloned human embryos. Japanese investigators created a solar cell that both generates and stores electricity. For the fourth year, the SCIENTIFIC AMERICAN 50 recognizes people, teams and organizations whose recent accomplishments, whether in research, business or policymaking, demonstrate leadership in shaping both established and emerging technologies.

In naming the winners of 2005, the magazine's editors and their expert advisers identified noteworthy trends related to technology ranging from polymer memory chips to a technique for regenerating damaged heart tissue. As you will see, the awards provide evidence once again that the application of new science, business acumen and policymaking skills not only can help build new machines but also can make a substantial difference in the way we all live.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
