Journals PLOS publishes seven peer-reviewed open-access journals. The journals vary in their selectivity and contain differing amounts of commentary articles from opinion leaders in a variety of scientific disciplines.The journals are editorially independent. They include PLOS ONE, which publishes all rigorous science across the full range of life and health sciences; the community journals (PLOS Genetics, PLOS Computational Biology, PLOS Pathogens, and PLOS Neglected Tropical Diseases); and our flagship journals, PLOS Medicine and PLOS Biology, highly selective journals publishing fewer than 10% of submissions along with a range of informative and influential non-research content. You can search the journals for specific articles here and you can sign up for e-mail Content Alerts for all our journals here.
New Genetic Twist: 4-Stranded DNA Lurks in Human Cells Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The odd structures are called G-quadruplexes because they form in regions of deoxyribonucleic acid (DNA) that are full of guanine, one of the DNA molecule's four building blocks, with the others being adenine, cytosine, thymine. The structure comprises four guanines held together by a type of hydrogen bonding to form a sort of squarelike shape. (The DNA molecule is itself a double strand held together by these building blocks and wrapped together like a helix.) The new visualization of the G-quadruplex is detailed this week in the journal Nature Chemistry. "I think this paper is important in showing directly the existence of this structure in vivo in the human genome, but it is not completely unexpected," said Hans-Joachim Lipps, of the University of Witten in Germany, who was not involved in the study.

Healthy Superfoods - Recipes for 7 Healthy Superfoods Dried licorice root may fight tooth decay, new research has found. But if you're not a fan, these foods can also help keep teeth, gums, and breath healthy, says Mark Wolff, D.D.S., Ph.D., of NYU College of Dentistry: Yogurt. The lactic acid may ward off periodontal disease, but skip the sugary varieties. Synthetic Biology "Synthetic biology" is an umbrella term that refers to a new set of powerful techniques for manipulating the fundamental molecular structures of life, including genes, genomes, cells and proteins. Techniques being developed under the "synthetic biology" rubric include the modification of existing bacteria to produce useful substances or perform new functions, the creation of novel artificial organisms from "scratch," and — less noted to date — the modification of animal and human genes. Synthetic biologists foresee a host of human applications, including new methods to produce drugs, biofuels and vaccines; to diagnose, prevent and cure disease; and — far more controversially — to screen, select, and modify genes for specified traits in embryos, children, and adults. Nonetheless, the field remains in its early days, and separating hype from real potential remains difficult. Such prospects raise concerns for social justice, human rights, and equality.

Democratic Party (United States) Since the 1930s, the party has promoted a social liberal platform.[2][11][12] Until the late 20th century the party had a powerful conservative and populist wing based in the rural South, which over time has greatly diminished. Today its Congressional caucus is composed mostly of progressives and centrists.[13] History The Democratic Party evolved from the Jeffersonian Republican or Democratic-Republican Party organized by Thomas Jefferson and James Madison in opposition to the Federalist party of Alexander Hamilton and John Adams.
CIHR Institutes CIHR integrates research through a unique interdisciplinary structure made up of 13 "virtual" institutes. CIHR's Institutes are not buildings or research centres, but networks of researchers brought together to focus on important health problems. Unconstrained by bricks and mortar, the Institute's virtual structure encourages partnership and collaboration across sectors, disciplines and regions. Each Institute is dedicated to a specific area of focus, linking and supporting researchers pursuing common goals.
