As an assistant professor in the School of Communication at American University, Matthew Nisbet studies scientific and environmental controversies. Part of his work involves examining the interactions between experts, journalists, and the public. He tracks these issues in his blog, Framing Science (http://scienceblogs.com/framing-science). In "The Future of Public Engagement", he and Dietram Scheufele, professor of life sciences communication at the University of Wisconsin in Madison

Should researchers "frame" their work, or is that just spin?

How much should Gardasil cost? Re: "How much should Gardasil cost?",1 which argues that Merck could cut the price of its HPV [human papillomavirus] vaccine by 90% and still profit. Stop complaining that publicly traded, for-profit companies charge too much for their products. They were not established to maximize the social good. If you believe they are denying treatment due to pricing, you have other options beyond haranguing them about morality: Go to a stockholders' meeting,

As she walks into her microbiology laboratory at Oregon State University, Kate Field hands her graduate student a Ziploc bag full of tubes of fecal samples. "These are just in from New Zealand," she says with a smile. For just being handed what essentially amounts to a bag of poop, her graduate student seems pretty excited as well. Now, the student's job is to test whether the genetic markers Field has developed can reliably identify what type of animal produced the sample. "Right no

His large and sensitive nose can easily detect the scent of unfamiliar humans, but his tiny eyes seem much less useful. Swollen and half covered by inflamed eyelids, they've been reduced to slits by debilitating conjunctivitis.

A few lazily sunbathing tigers lift their heads in curiosity. In a matter of seconds, one tiger leaps toward the confused creature, which musters up enough energy to flutter away. But, the bird's small victory is short-lived: The tiger, followed by several freeloaders, ch

David Allis from Rockefeller University and colleagues used a biochemical pull-down assay and found that the protein WDR5, a common part of histone methyltransferase complexes, associates specifically with dimethylated H3K4 nucleosomes.

While the internal mechanisms that guide cell migration have been described for individual cells, Pernille Rørth at the European Molecular Biology Laboratory in Heidelberg, Germany, and colleagues examined signaling activation in Drosophila border cells to uncover how groups of cells migrate collectively. They found that in the later phase of migration, leading cells have more mitogen-activated protein (MAP) kinase activation than trailing cells.1 "What's setting direction

To better understand how evolutionary pressures have helped shape genetic variation in Arabidopsis thaliana, Detlef Weigel from the Salk Institute for Biological Studies in La Jolla, Calif., and colleagues used high-density oligonucleotide arrays to look at single nucleotide polymorphisms of 20 diverse strains of the plant.1 The group found that, since 2000, abo

N. Stern-Ginossar, et al., "Host immune system gene targeting by a viral miRNA." Science, 317:376-81, July 20, 2007. Upon infection of its host, human cytomegalovirus (HCMV) expresses a miRNA that directly down-regulates expression of an immunorelated gene, MICB. Thus, it appears that HCMV has developed two distinct mechanisms to down-regulate expression of the same immunorelated gene, with the RNA-based strategy presumably being more ancient. -
