The Perils of Strong Copyright: The American Library Association and Free Culture

The American Library Association has been involved in an ongoing public relations campaign in order to attempt to convince the academic publishing world that the Open Access model is the correct one for academe. However, they have not followed suit with their own publications. This paper is an exploration of this duality, set in a framework of the history of copyright and the Open Access and Free Culture movement. The history of copyright in the United States is presented with special emphasis to its relationship with libraries, and the philosophy of the Free Culture movement is examined in the same light. Specific ALA publications' copyright policies are noted, and compared/contrasted with the public positions that the ALA has taken on Open Access

Identification of genes required for eye development by high-throughput screening of mouse knockouts.

Despite advances in next generation sequencing technologies, determining the genetic basis of ocular disease remains a major challenge due to the limited access and prohibitive cost of human forward genetics. Thus, less than 4,000 genes currently have available phenotype information for any organ system. Here we report the ophthalmic findings from the International Mouse Phenotyping Consortium, a large-scale functional genetic screen with the goal of generating and phenotyping a null mutant for every mouse gene. Of 4364 genes evaluated, 347 were identified to influence ocular phenotypes, 75% of which are entirely novel in ocular pathology. This discovery greatly increases the current number of genes known to contribute to ophthalmic disease, and it is likely that many of the genes will subsequently prove to be important in human ocular development and disease

The Perils of Strong Copyright: The American Library Association and Free Culture

The current state of intellectual property law is labyrinthine in every sense: it is difficult to follow, full of blind alleys, and the only people who know the way through it are the ones who designed it in the first place. Pamela Samuelson notes in Towards a New Politics of Intellectual Property, “copyright industry groups have cultivated relationships with policy makers in the executive and legislative branches over a long period of time” (98) and these relationships have been used to maintain control over copyrighted materials far beyond the length of time of commercial success of said materials. James Boyle noted that “the ground rules of the information society are being laid down by lawyers (strike one) employed by the biggest players in the field (strike two) all with little public debate or press scrutiny.” (Boyle, “Sold Out”) My goal in this paper will be to examine the history of copyright, attempt to unite some of the disparate aspects of the open information meme, and finally to consider how this meme is being distributed (or not distributed) by academic librarians. I will also attempt to make prescriptive suggestions that might assist librarians in seeing the strengths of the Open Information memepool

Distinct Roles for Motor Neuron Autophagy Early and Late in the sod1\u3csup\u3eg93a\u3c/sup\u3e Mouse Model of Als

Mutations in autophagy genes can cause familial and sporadic amyotrophic lateral sclerosis (ALS). However, the role of autophagy in ALS pathogenesis is poorly understood, in part due to the lack of cell type-specific manipulations of this pathway in animal models. Using a mouse model of ALS expressing mutant superoxide dismutase 1 (SOD1G93A), we show that motor neurons form large autophagosomes containing ubiquitinated aggregates early in disease progression. To investigate whether this response is protective or detrimental, we generated mice in which the critical autophagy gene Atg7 was specifically disrupted in motor neurons (Atg7 cKO). Atg7 cKO mice were viable but exhibited structural and functional defects at a subset of vulnerable neuromuscular junctions. By crossing Atg7 cKO mice to the SOD1G93A mouse model, we found that autophagy inhibition accelerated early neuromuscular denervation of the tibialis anterior muscle and the onset of hindlimb tremor. Surprisingly, however, lifespan was extended in Atg7 cKO; SOD1G93A double-mutant mice. Autophagy inhibition did not prevent motor neuron cell death, but it reduced glial inflammation and blocked activation of the stress-related transcription factor c-Jun in spinal interneurons. We conclude that motor neuron autophagy is required to maintain neuromuscular innervation early in disease but eventually acts in a non–cell-autonomous manner to promote disease progression
