Since beginning his career as an engineer for Douglas Aircraft, Frederick Sachs has been a research fellow at NIH's biophysics laboratory, and served as both an NIH physiology reviewer and NSF consultant. His most recent work, as professor of physiology and biophysics at the University of Buffalo, pinpointed a protein in tarantula venom as a potential drug candidate to treat atrial fibrillation. In a provocative Opinion, Sachs proffers that funneling more money into the NIH budget ha

How far has open access come in a decade? And where will it go in the next?

Fixing authorship In his column "Me first!" Glenn McGee proposes two changes to fix the system of scientific authorship.1 Drawing simple authorship rules is easy when a paper requires a single field of expertise and can be understood by all authors. However, many papers require that people from different fields come together, and not all authors will understand all the aspects of the paper, even if they devised part of the strategy. How can rules deal with that? Disputes aris

At a daring six meters, the droning becomes ominous and insistent. At two meters away, the humming is so malevolent that the sky seems to darken. "Beautiful music, yes?" says Nikola Kezić, as if there is no doubt. Arranging folding ch

While working on her PhD in 1992, Karen Lips went to Las Tablas, Panama, to study the biology of a tree frog, Hyla calypso, an inch-long, spiny, bright-green creature. As she walked through transects in the forest, measuring and sexing frog individuals, here and

That's just one of several neuroscience-related pieces in this issue, which you may very well be reading at the Society for Neuroscience's annual meeting in San Diego, from November 3-7.

In Jennifer Elisseeff's small tissue-culture room at Johns Hopkins University, she points to an eraser-sized pellet of two-layered hydrogel floating in culture medium. She explains how the cells, encapsulated within juxtaposed layers of gel, exchange signals to help them grow. Knowing what those signals are could help her design a hydrogel that would regenerate diseased tissue. As a teen

In order to excite a fluorophore labeling the tissue, two long-wavelength, low-energy photons must meet nearly simultan
