Contributors Judy Lieberman, senior investigator at the Immune Disease Institute and the program in cellular and molecular medicine at the Children’s Hospital Boston, came to be a physician through an unusual pathway. Before attending medical school, Lieberman earned a doctorate in theoretical physics, but turned to a career in medicine so she could directly impact peoples’ lives. “I wanted to do something more socially useful,&#

Three New Paradigms

By Sarah Greene Three New Paradigms The way we research cancer and present our data to the world is undergoing a major revolution. Open Science embraces open access publishing and advances the underlying concept a few light years. Cancer is very personal. That’s brought home in the lead paragraph of the lead story of this issue, Building a Better Mouse. The patient with lung cancer asks her doctor if she might qualify for a promising targeted t

Mail

Mail The Next New Thing Excellent idea to try to promote interactive behavior among life scientists.1 There is far too little interaction between scientists who are, understandably, frightened of divulging their work. There should be nothing wrong with talking about technical issues, though; that’s why so many forums have sprung up. I won’t be tempted by a t-shirt, though, which runs the risk of making your idea look a bit gimmick

Ancient Aminos

Iglésias recognized that a species of highly endangered fish was actually composed of two separate spe

But For the Grace of Genes

By Elaine Howard Ecklund and Conrad Hackett But For the Grace of Genes Science may consider fundamentalism a threat, but our study shows that most scientists are spiritual—suggesting both sides may have more in common than they think.

Down with Reviews

By Steven Wiley Down with Reviews Review articles simply don’t deserve all the citations they receive. Cited discoveries & hypotheses should always refer to the original literature. There has been a proliferation of review articles and review journals over the last decade, and it is easy to see why. Biologists find them useful to keep up with increasingly complex science, and publishers find them an easy way to increase the im

Building a Better Mouse

A notoriously poor proxy for the human experience of cancer, mouse models are now undergoing a major renovation.

In the Blood

As a graduate student at the University of Maastricht in The Netherlands in the mid-1980s, Pieters was studying the biochemistry of blood coagulation. “My first week there I had to go

New Smoking Gun?

By Jef Akst New Smoking Gun? Teams come together to target the genes behind lung cancer, but the hunt is far from over. Image modified from © Alfred Pasieka / Photo Researchers, Inc. Scientists have known for years why more than 1 million people die of lung cancer every year—smoking. Thus, when it came to looking for a genetic basis to lung cancer, “there was a lot of skepticism” about the importance of such rese

The viral skinny

(Cited 163 times) The finding: When the husband and wife team of Yuan Chang and Patrick Moore started looking for the causes of Merkel cell carcinoma (MCC), a rare skin cancer, they suspected a virus. They had discovered that Kaposi’s sarcoma was caused

(Cited 71 times) The finding: The reason why more people get the flu during colder months has long been a mystery. To investigate the role of weather conditions on flu transmission, researchers at the Mount Sinai School of Medici

Age: 36 Lin He didn’t learn much biology in high school, as secondary education in her native China focuses more on math, physics, and chemistry. That “limited exposure” made biology “very mysterious,” recalls He, who decided to make it her major when she g

Sizing up Nanoparticles

By Kelly Rae Chi Sizing up Nanoparticles How to put nanoparticles to work in drug development. Nanoparticles are increasingly found in drug development. Researchers are using them in designing treatments for tumors, infections, and brain diseases, as well as for imaging techniques that enhance visualization of molecular-scale events in brain tissue and culture dishes. But so far, says biochemist Michael Sailor of the University of Californi

New NIH grant applications

By Jef Akst New NIH grant applications How to cut sentences, not substance As of January 25 of this year, the National Institutes of Health has shortened the page limits for most sections of its grant applications, brining the total page limit for R01 grants down from 25 to 12. While many scientific editors advocate a shorter-is-better philosophy all the time, with the new application format, "you need to jam things into a shorter space,"

Darwin to Joseph Hooker, 1844

By Katherine Bagley Darwin to Joseph Hooker, 1844 Researchers and historians have collected approximately 15,000 letters written both to and by Charles Darwin in an effort to better understand his life and science. One of his most frequent contacts was Joseph Dalton Hooker, a botanist who helped identify many of the plant specimens collected during Darwin’s HMS Beagle journey, including his famed stop at the Galapagos Islands. Their discourse, which spann
