Features - Stop Ticks Reduce your chances of getting a tickborne disease by using repellents, checking for ticks, and showering after being outdoors. If you have a tick bite followed by a fever or rash, seek medical attention. Gardening, camping, hiking, and playing outdoors – when enjoying these activities, don't forget to take steps to prevent bites from ticks that share the outdoors. Ticks can infect humans with bacteria, viruses, and parasites that can cause serious illness. "The Man Who Runs The World's Smartest Website" (in The Observer) Since the mid-1960s John Brockman has been at the cutting edge of ideas. He is a passionate advocate of both science and the arts, and his website Edge is a salon for the world's finest minds To say that John Brockman is a literary agent is like saying that David Hockney is a photographer. For while it's true that Hockney has indeed made astonishingly creative use of photography, and Brockman is indeed a successful literary agent who represents an enviable stable of high-profile scientists and communicators, in both cases the description rather understates the reality. More accurate ways of describing Brockman would be to say that he is a "cultural impresario" or, as his friend Stewart Brand puts it, an "intellectual enzyme".
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.
Occupational Outlook Handbook, 2010-11 Edition Funeral Directors Funeral directors, also called morticians and undertakers, manage funeral homes and arrange the details of a funeral. view profile » Insurance Underwriters Insurance underwriters decide whether to provide insurance and under what terms. They evaluate insurance applications and determine coverage amounts and premiums. Indoor Air Quality Introduction to Molds Molds produce tiny spores to reproduce. Mold spores waft through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods.
Facts about Ecstasy MDMA (3,4-methylenedioxymethamphetamine), commonly referred to as ecstasy or molly, is a drug that is sold either as a pressed pill taken orally, or as a powder that is snorted or swallowed. MDMA’s effects resemble those of both stimulants and psychedelics. A typical dose of 100 to 125 mg lasts four to six hours. People who use MDMA describe themselves as feeling open, accepting, unafraid and connected to people around them. Typically used in social settings, especially among the rave and dance club cultures, MDMA’s effects are stimulated by visuals, sounds, smells and touch. Some people experience nausea at the outset, but after about forty-five minutes, most people report feelings of relaxation and clarity. 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. 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. 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.
