Contributors William J. Pearce is head of the Genito-Urinary & Reproductive Pharmacology section of the Faculty of Pharmacology & Drug Discovery at F1000, and a professor of physiology at Loma Linda University School of Medicine. He writes in this issue about the inappropriate use of citations in science papers, a subject with which he is very familiar—he published his first peer-reviewed paper 30 years ago, has served on dozens of study sections
By Sarah Greene Peer Review and the Age of Aquarius It’s time to reinvent the system that validates scientific discovery The most wonderous disruption of all: the idea that papers and data have lives beyond their original posting. This month our new column, Thought Experiment, considers whether mathematics can answer the deepest perplexities of science, such as evolution and consciousness. Here’s a corollary: Can metrics point to the great
Mail Earmark Science The practice of funding science with congressional earmarks1 is just the tip of the iceberg. I fear that we are experiencing a general disintegration of the quality and integrity of American science and engineering. From fundamental research to operating decisions like the ones made on the Deepwater Horizon that led to the disaster in the Gulf, bad technical decisions are being made—more often than not driven by politicians, lawye

Earle On a frigid weekend in the winter of 2004, a medical charity held a meeting at the Yarrow Hotel in Park City, Utah, to discuss a problem. It had been nearly ten years since geneticists Irwin McLean and Frances Smith had discovered the genetic underpinnings of pachyonychia congenita, a rare and extremely painful skin disorder. But a cure was nowhere in sight.
By Richard P. Grant Creative madness Consider a brick. What can you do with it? Your answer to that question can be a measure of how creative you are. Örjan de Manzano, a PhD student at the Karolinska Institutet in Stockholm, is using the query to explore the potential neurological link between creativity and psychoses. Highly creative people and those with mental disorders are usually better at seeing novel connections between ideas or objects—at t

Piston proton pump » The X-ray structure of a membrane complex involved in aerobic respiration (and implicated in neurodegeneration) reveals an unusual piston-like mechanism for pumping protons across the mitochondrial membrane, and provides clues for developing drugs against Parkinson’s and other related diseases.

By William J. Pearce Citations: Too Many, or Not Enough? We are citing too many papers inappropriately. Students, colleagues and coauthors must critically read each paper cited in its entirety. For more than 100 years, before PubMed was freely accessible via the Internet, the medical literature was commonly accessed via Index Medicus, the first comprehensive index of journal articles available through the Library of Medicine. Finding the perfect reference often necess

But some of the most important findings have been published in considera
Many say the peer review system is broken. Here’s how some journals are trying to fix it.

One of the world’s most productive,

In it, he defend

GAUGLER / PHOTO RESEARCHERS, INC.

By Jeffrey M. Perkel Probing Proteins How to make sense of proliferating proteomics data…even if you’re not a proteomicist. Pity the poor protein biologist. DNA sequence gurus have GenBank, structural biologists, PDB. But those looking to data-mine the spectral peaks and valleys of today’s burgeoning proteomics literature are out of luck. Or are they? Several freely available databases are dedicated to the
