GREEN REVOLUTION: DISCOVER

submitted by: nsf
A trip to Snowy River, a bright white crystalline formation found deep within Fort Stanton Cave in New Mexico, reveals a lot about life and energy in unexpected places. Host Lisa Van Pay meets Diana Northup and Monica Moya, researchers who study life in caves. As they explore the cave they ask questions, think of possible answers and ways to test them, and discuss how to share their findings with the community. Together, science and engineering have resulted in advancements that have changed...

Ouch! Single Cell Wound Repair in Drosophila Embryos

submitted by: JCB
Individual cells must quickly repair any disruptions to their plasma membrane. Abreu-Blanco et al. describe how early Drosophila embryos remodel their membranes and cytoskeleton to seal cell surface wounds. This biosights episode presents the paper by Abreu-Blanco et al. from the May 2, 2011 issue of The Journal of Cell Biology, and includes an interview with senior author Susan Parkhurst (Fred Hutchinson Cancer Research Center, Seattle, WA). Produced by Caitlin Sedwick and Ben Short....

Standardization of starter culture for rice wine (Tapuy) processing

submitted by: UP Los Baños
A report on a study aimed to develop instant starter culture for rice wine (tapuy) processing, by (1) isolating and identifying useful microorganisms for starter culture production; (2) evaluating the saccharifiying ability and alcohol production of the isolated strains; (3) developing a starter culture and determine its storage stability; and (4) evaluating the quality of rice wine produced by the developed starter culture. Dr. Erlinda I. Dizon Food Science Cluster College of...

Single molecule analyses of DNA in environmental microbes

submitted by: dougramsey
Comprehensive characterization of genomic composition in environmental microbial samples has been challenging, because the majority of microorganisms are difficult to culture. Additional challenges include a high degree of genetic diversity between and within species, various level of relative abundance and ubiquitous presence of cell-free DNA. Single cells or single molecules genomic assays hold great promise for tackling these challenges. Recent progresses in the developments of these...

Setting the Stage: Mobilizing the Metagenomics Community

submitted by: dougramsey

About 250 leaders in the emerging science of metagenomics converged at the UC San Diego division of the California Institute for Telecommunications and Information Technology (Calit2) earlier this month for the third Annual International Conference on Metagenomics. The conference was a week-long opportunity to share data and discuss the latest research, explore how advances in computing and sequencing technologies might be of benefit, and build or strengthen collaborations in the field.

Electromicrobiology: Novel Approaches for Investigating Charge Transfer and Energy Transformation in Microbial Systems

submitted by: dougramsey
Respiratory microorganisms capture energy for growth and maintenance as they transfer electrons from energy sources to appropriate electron acceptors. Controlling the availability of electron donor and acceptor pairs provides opportunities for investigating fundamental aspects of energy transformation and distribution in defined and un defined microbial cultures. For example, we have noted that in all bacteria investigated to date electron acceptor limitation prompts the production of...
