Change the World: Science and Engineering Careers Fair

submitted by: nsf
For two days in September, Congressman Frank Wolf and the National Science Foundation (NSF) hosted a fair at the Dulles Town Center in Virginia that inspired young people to consider careers in science, technology, engineering and mathematics (STEM). Scientists, engineers and tech companies set up exciting, interactive, educational exhibits and activities that highlighted their fascinating NSF funded research. Guests could also enjoy a variety of fun science and engineering-related...

biosights: October 28, 2013 - A framework for understanding muscle microtubules

submitted by: JCB
The microtubules of skeletal muscle fibers are arranged into an orthogonal grid, but how this network is formed is unknown. Oddoux et al. reveal that the network is built by dynamic microtubules nucleated from Golgi elements. This biosights episode presents the paper by Oddoux et al. from the October 28, 2013, issue of The Journal of Cell Biology and includes an interview with senior author Evelyn Ralston (NIH, Bethesda, MD). Produced by Caitlin Sedwick and Ben Short. See the associated...

Clinical and microbiological effects of Lactobacillus reuteri probiotics in the treatment of chronic periodontitis: a randomized placebo-controlled study

Aim The aim of this randomized placebo-controlled clinical trial was to evaluate the effects of Lactobacillus reuteri-containing probiotic lozenges as an adjunct to scaling and root planing (SRP). Material and Methods Thirty chronic periodontitis patients were recruited and monitored clinically and microbiologically at baseline, 3, 6, 9 and 12 weeks after therapy. All patients received one-stage full-mouth disinfection and randomly assigned over a test (SRP + probiotic, n = 15) or...

biosights: September 30, 2013 - The nodal network

submitted by: JCB
In addition to specialized actin structures such as lamellipodia and stress fibers, cells are thought to contain a contractile actomyosin matrix that maintains cell shape. Luo et al. describe the organization and dynamics of an actomyosin network that may fulfill this function. This network is formed by actin nodes that contain the formin DAAM1 and the crosslinker filamin A, and that are connected to each other by myosin II. This biosights episode presents the paper by Luo et al. from the...

Hydrophis Belcheri normally known as faint-banded ocean snake or even Belcher’s ocean snake, is the majority of venomous snake range present in the depths associated with ocean can be a kinds linked to elapid ocean snake. It's the the majority of venomous ocean snake. It offers the genial characteristics and it also would probably needed to be excessive mistreatment ahead of biting down hard. Usually those who find themselves injured will be the anglers once they clean the netting.
