(Waseda University) Researchers compared the photosynthetic regulation in glaucophytes with that in cyanobacteria, to elucidate the changes caused by symbiosis in the interaction between photosynthetic electron transfer and other metabolic pathways. Their findings suggest that cyanelles of the glaucophyte Cyanophora paradoxa retain many of the characteristics observed in their ancestral bacteria, and that C. paradoxa is the primary symbiotic algae most similar to cyanobacteria than other lineages of photosynthetic organisms in terms of metabolic interactions.

A group of Japanese researchers became the first in the world to discover that bacteria in the salivary microbiome exhibit circadian rhythm and act as if it were a part of the human body, just like organs and cells. A circadian clock of a 24-hour cycle exists in most organisms including humans, adjusting the circadian rhythm to control various biological functions which occur during the day and at night. The circadian clock transmits information to cells and organs in the body from the brain and sustains the organism's health. Until recently, circadian rhythm was a phenomenon mostly observed in cells and organs of organisms, but the researchers found that it also exists in the microbiome of saliva of humans. "We were able to prove that the salivary microbiome exhibit circadian rhythm, and our study will help promote healthier lifestyles," says Masahira Hattori, a professor of life science at Waseda University who participated in the research. "Instead of the conventional and invasive approach of drawing blood, doctors will be able to evaluate a person's stress level and health conditions by checking their saliva. They can look for disturbances in the circadian clock, which are associated with increased risk of developing lifestyle diseases, such as obesity, diabetes and cancer. It will also contribute to finding new ways to diagnose these diseases." This research is published in DNA Research. In this study, saliva samples were collected from six healthy men and women with 4-hour intervals for 3 days to examine changes in salivary microbiomes longitudinally during the day. Using the metagenomic analysis, the researchers studied in detail the types of bacteria in the salivary microbiomes and the oscillation of its composition. The analysis revealed the following: These observations suggest that human microbiomes across the body interact with various signals in response to the body's physiological conditions and act as if they are a part of the body like organs and cells. Because the factors or signals affecting the circadian oscillation of the human salivary microbiome are yet known, the research group intends to conduct further investigation and find out the differences in biological roles of diurnal and nocturnal bacteria in the oral cavity.

This article reviews the progress made over the last 20 years in the development and applications of liquid xenon detectors in particle physics, astrophysics, and medical imaging experiments. A summary of the fundamental properties of liquid xenon as radiation detection medium, in light of the most current theoretical and experimental information is first provided. After an introduction of the different type of liquid xenon detectors, a review of past, current, and future experiments using liquid xenon to search for rare processes and to image radiation in space and in medicine is given. Each application is introduced with a survey of the underlying scientific motivation and experimental requirements before reviewing the basic characteristics and expected performance of each experiment. Within this decade it appears likely that large volume liquid xenon detectors operated in different modes will contribute to answering some of the most fundamental questions in particle physics, astrophysics, and cosmology, fulfilling the most demanding detection challenges. From detectors based solely on liquid xenon (LXe) scintillation, such as in the MEG experiment for the search of the rare " μ→eγ " decay, currently the largest liquid xenon detector in operation, and in the XMASS experiment for dark matter detection, to the class of time projection chambers which exploit both scintillation and ionization of LXe, such as in the XENON dark matter search experiment and in the Enriched Xenon Observatory for neutrinoless double beta decay, unrivaled performance and important contributions to physics in the next few years are anticipated. © 2010 The American Physical Society.

We introduce a transformation of general higher-order Markov random field with binary labels into a first-order one that has the same minima as the original. Moreover, we formalize a framework for approximately minimizing higher-order multilabel MRF energies that combines the new reduction with the fusion-move and QPBO algorithms. While many computer vision problems today are formulated as energy minimization problems, they have mostly been limited to using first-order energies, which consist of unary and pairwise clique potentials, with a few exceptions that consider triples. This is because of the lack of efficient algorithms to optimize energies with higher-order interactions. Our algorithm challenges this restriction that limits the representational power of the models so that higher-order energies can be used to capture the rich statistics of natural scenes. We also show that some minimization methods can be considered special cases of the present framework, as well as comparing the new method experimentally with other such techniques. © 2006 IEEE.
