The Broad Institute and Rockefeller University disagree over which scientists should be named as inventors on certain patents involving the gene-editing technology.

Contributors Pascale Cossart is fascinated by the bacterium Listeria monocytogenes. Cossart started studying the deadly pathogen in 1986 at the Pasteur Institute. At the time, numerous labs were trying to identify genes responsible for virulence in various bacteria. Her work with Listeria led to new concepts in infection biology. "By chasing answers to the questions that struck my curiosity, I've let Listeria lead me into new fiel
By Richard Gallagher The Last Act My final editorial. Ten problems I believe could bollix biology in years to come. After seven-and-a-half years as editor, and with 130-plus editorials behind me, I’m facing the tyranny of the blank page for the final time: my last editorial. How lucky I’ve been to be editor of this publication at this time. I often think of the poor editor of a glossy golf magazine who talked at a publishing me
Mail Promises, Promises Ok, this article about the dangers of scientific predictions1 is well written—but it is not saying anything hundreds have not said. Scientists make crazy promises. Hubris causes us to assert that we know what is right as though we have not been bitten by unintended consequences many, many times. But…there is plenty of blame to go around. Patients demand cures for complex diseases as though merely stomping your

Thankfully, Barry Quart’s HIV drug appeared to be working. In recent Phase 1 testing, the compound, which blocks the activity of an enzyme HIV needs to continue its replication cycle, appeared to be well tolerated

Courtesy of Sophie Dumont It was the last week of her summer of research at Woods Hole Marine Biological Laboratory on the coast of Massachusetts in 2007, and biophysicist Sophie Dumont decided to try one final experiment. With the state-of-the-art microscopes that had been loaned to the research station, Dumont started pressing on mammalian cells a
While mulling over ideas for a group project in a graduate-level class in community ecology in 2007, PhD student Ryan O’Donnell recalled a question that had been nagging him for years.
—Jef Akst Desperately seeking seahorses Where were they? It was a question that plagued me during my anxiety-ridden dives in the summer of 2008, as I paddled through the bathlike waters of Tampa Bay, Fla., hoping to find enough seahorses to complete my graduate degree in evolutionary biology. After a month and a half of fruitless searching, I finally threw in the rag and headed back to Indiana University with the dreaded “failed field seas
By Brendan Borrell A pioneer's perils Homme Hellinga © Les Todd / Duke University On a rainy morning at the National Institutes of Health campus in Bethesda, Md., last fall, Duke University biochemist Homme Hellinga took the stage to sum up what he had been doing over the last 5 years with the $2.5 million Pioneer award he received in 2004. Unlike other NIH grants that require a strict game plan with concrete goals, the Pioneer award is a kind o
By Elizabeth A. Corley and Dietram A. Scheufele Outreach Going Wrong? When we talk nano to the public, we are leaving behind key audiences. Scholars, policy-makers, and outreach specialists in the nanotechnology community may be struggling with toxicological data and regulatory frameworks, but they seem to be able to agree on one thing: The public is unaware of the new technology and uninformed about the science behind it. Ironicall
By Steven Wiley Mind Your Manners We need to treat each other with respect, or all of science will suffer. Being dismissive and emotional during public discussions makes you look bad to other people and erodes your credibility. There has been a lot of talk in the media about the loss of courtesy in modern society. By many criteria, it seems that people in general have lost a degree of politeness. Reading some of the online comments after several rec
By Bob Grant Should Evolutionary Theory Evolve? Some biologists are calling for a rethink of the rules of evolution. Evolution, by its very nature, is a dynamic process. But just as fluid are humankind’s efforts to understand, describe, and conceptualize that process. Out went Lamarck, in came Darwin. Mendel’s insights set the rules for genetic inheritance, then certain exceptions to Mendel’s rules materialized. So forth

Maurice Hilleman examined the swollen bumps on his daughter’s neck. It was 1963. She had the mumps, a common childhood disease at the time, caused by a virus that inflames the salivary glands. Most cases are mild, but severe inf

(Cited in 96 papers) The finding: To be released from some cells, HIV-1 requires an accessory protein called Vpu, suggesting that these cells carry a host factor that inhibits the release of virions

Inspired by a model of DNA’s double helix, the 5- or 6-year-old Kieffer drew a replica of the structure that has hung on her walls ever since. “DNA was beautiful and it helped spark my interest in biology,” she says.

If you’ve invented an automated tool, colleagues in other labs could very likely benefi
