Induction of Mutations in a Bacterial Virus

In the course of experiments designed for other purposes a paradoxical observation was made: phage λ, inactivated by UV irradiation, when adsorbed onto sensitive bacteria was reactivated when a further dose of UV was given to the phage-bacterium complexes. Among the reactivated phages a fairly large proportion were mutants. A description of these findings and a discussion of their implications will be found below

Monosodium glutamate delivered in a protein-rich soup improves subsequent energy compensation

Previous research suggests that monosodium glutamate (MSG) may have a biphasic effect on appetite, increasing appetite within a meal with its flavour-enhancing effect, but enhancing subsequent satiety due to its proposed role as a predictor of protein content. The present study explored this by assessing the impact of a 450 g soup preload differing in MSG concentration (1 % MSG added (MSG+) or no MSG (MSG-)) and nutrient content (low-energy control or high-energy carbohydrate or high-energy protein) on rated appetite and ad libitum intake of a test meal in thirty-five low-restraint male volunteers using a within-participant design. Protein-rich preloads significantly reduced intake at the test meal and resulted in more accurate energy compensation than did carbohydrate-rich preloads. This energy compensation was stronger in the MSG+ protein conditions when compared with MSG+ carbohydrate conditions. No clear differences in rated appetite were seen in MSG or the macronutrient conditions alone during preload ingestion or 45 min after intake. Overall, these findings indicate that MSG may act to further improve energy compensation when provided in a protein-rich context

Know Your Audience - A Multi-pronged Approach to Information Transfer

Grape Rootworm – looking at alternatives for managing an old foe that is making a comeback in Lake Erie region vineyards

Grape rootworm is making a comeback in Lake Erie vineyards, reducing vine size and yield and Cornell extension and research staffs are ensuring growers have the tools needed to effectively manage this pest

Archive What I See Now

The web has become a repository for much of our social culture. Thus, humanities scholars have recognized the need for archiving web objects to support their research. We propose to build an open-source tool to support this personal-scale web archiving. We will build a Firefox add-on to create an archive of a web page or web site from the perspective of the browser. This means that web pages requiring authentication, pages on social media sites, and pages displayed after some user interaction can all be archived in the standard Web ARChive (WARC) format. This tool will provide easy access to web archiving and give users the ability to "archive what I see now." The tool will also allow users to upload generated WARC files to a specified server for later access. With this tool, collaborating scholars could upload their WARCs to a common server to create special-purpose collections of various topics. These collections could then be accessed by standard web archive tools

Technology Adoption and Outreach Efficient Vineyards USDA/NIFA SCRI Project

NYS IPM Type: Project ReportOne of the objectives of the Outreach and Adoption team for the USDA/NIFA SCRI project, Efficient Vineyard’s, was to determine the current knowledge base of grape growers regarding the use of spatial data for variable rate vineyard management, as well as identify the preferred learning styles of growers. A survey was created and disseminated to the members of the project team for review. A total of 181 surveys were completed by growers, members of the grape industry, as well as members of the Efficient Vineyards advisory committee. Fifty-eight growers completed a hard copy version of the survey at a California meeting conducted by Kaan Kurtural, 40 growers participated during “Coffee Pot” Meetings held in the Lake Erie grape belt of New York and Pennsylvania, 16 members of the advisory committee participated and 67 responses were collected via an on-line version of the survey using Survey Monkey. Participation in the survey was concentrated in California, New York and Pennsylvania but the on-line survey allowed for participation by growers from 15 additional states

Quantifying Orphaned Annotations in Hypothes.is

Web annotation has been receiving increased attention recently with the organization of the Open Annotation Collaboration and new tools for open annotation, such as Hypothes.is. We investigate the prevalence of orphaned annotations, where neither the live Web page nor an archived copy of the Web page contains the text that had previously been annotated in the Hypothes.is annotation system (containing 20,953 highlighted text annotations). We found that about 22% of highlighted text annotations can no longer be attached to their live Web pages. Unfortunately, only about 12% of these annotations can be reattached using the holdings of current public web archives, leaving the remaining 88% of these annotations orphaned. For those annotations that are still attached, 53% are in danger of becoming orphans if the live Web page changes. This points to the need for archiving the target of an annotation at the time the annotation is created
