    Newfound Nitrogen Harmony Saves Tropical Forest Trees by Brian Thomas, M.S. * New research shows that tropical forests quickly recover after clear-cutting by using clever mechanisms to locate sufficient levels of nitrogen that they need to thrive. Publishing in the journal Nature, an international team of researchers representing Princeton University, the Smithsonian Tropical Research Institute, the University of Copenhagen, and Yale University tracked tropical forest growth. They paid particular attention to the growth-rate patterns of "nitrogen-fixing" trees.1 (Nitrogen fixation is the process whereby atmospheric nitrogen is converted into more usable compounds.) Actually, the trees don't perform this "fixing" task alone...

    There was a small surprise: Viking found nitrogen to be the second most abundant gas in the Martian air, but Curiosity’s measurements revealed a nearly equal abundance of nitrogen and argon, a stable noble gas. Mission scientists are puzzled, but suspect it might have to do with the different tools used to sample the atmosphere.

    An 18-year-old woman has had her stomach removed to save her life after drinking a cocktail containing liquid nitrogen. Gabby Scanlan had been drinking at Oscars wine bar in Lancaster to celebrate her 18th birthday when she was left feeling breathless. After developing serious stomach pain, she was rushed to Lancaster Royal Infirmary where she diagnosed with a perforated stomach. The young woman, from the village of Heysham in Lancashire, then underwent emergency surgery to remove her stomach, reported ITV News. … Liquid nitrogen is pure nitrogen in a liquid state at a very low temperature. It boils at –196°C...

    State Sen. Loni Hancock, D-Berkeley, is pushing legislation to end California's death penalty. "Capital punishment is an expensive failure and an example of the dysfunction of our prisons," she explained in a statement. "California's Death Row is the largest and most costly in the United States. It is not helping to protect our state; it is helping to bankrupt us." You have to hand this to death-penalty opponents: For decades, capital punishment opponents have tried to thwart California's 1978 death-penalty law with frivolous appeals that clog courts, delay punishment and burn through taxpayers' dollars. They now have been so successful...

    TEPCO ready to inject nitrogen into No.2 reactor Tokyo Electric Power Company is ready to inject nitrogen into the containment vessel of the Number 2 reactor at its Fukushima Daiichi nuclear plant to prevent hydrogen blasts. The company says it will monitor radiation levels around the compound more closely as the nitrogen may force out tiny amounts of gas containing radioactive substances. Work is underway at the damaged nuclear plant to decontaminate water and inject it back into the reactor for cooling. But if the reactors are cooled to a stable level, less moisture will be produced, raising the ratio...

    Earth and Environmental Scientist Peter Doran recently surveyed 3,146 scientists in an effort to clarify the “scientific consensus” on global warming. Professor Doran has previously complained that his study revealing cooling in the Antarctic had been misinterpreted, causing confusion in the global warming debate. Here we go again.

    While carbon dioxide has been getting lots of publicity in climate change, reactive forms of nitrogen are also building up in the environment, scientists warn. "The public does not yet know much about nitrogen, but in many ways it is as big an issue as carbon, and due to the interactions of nitrogen and carbon, makes the challenge of providing food and energy to the world's peoples without harming the global environment a tremendous challenge," University of Virginia environmental sciences professor James Galloway said in a statement. "We are accumulating reactive nitrogen in the environment at alarming rates, and this...

    Calculating the Risks in Pakistan A small group of U.S. military experts and intelligence officials convened in Washington for a classified war game last year, exploring strategies for securing Pakistan's nuclear arsenal if the country's political institutions and military safeguards began to fall apart. The secret exercise — conducted without official sponsorship from any government agency, apparently due to the sensitivity of its subject — was one of several such games the U.S. government has conducted in recent years examining various options and scenarios for Pakistan's nuclear weapons: How many troops might be required for a military intervention in...

    nitrogen the Vikings left behind 11 September 2006 From New Scientist Print Edition. Discovering ancient settlements is often rather hit and miss, but the odds would be improved with a bit of chemical analysis. Plants growing over old sites of human habitation have a different chemistry from their neighbours, and these differences can reveal the location buried ruins. Plants mostly take in nitrogen from the soil as the isotope nitrogen-14, with just a dash of nitrogen-15. Plants growing above archaeological sites in Greenland, however, seem to have absorbed a larger dose of nitrogen-15. Rob Commisso and Erle Nelson from...

    As prices at the pump continue to rise, drivers are always looking for new solutions for savings. The use of nitrogen is rising in popularity in the Bay area and costs less than a tank of gas. "Fuel savings for an automobile is the highest priority right now, I think," Olin Mott Tires President Rick Mott said. "One of the advantages of nitrogen, of course, is the fuel savings." Race car drivers and airlines have been using it for decades and so are an estimated 10 percent of tire shops around the country. Auto experts said nitrogen is retained in...

    Small but perfectly formed, Pelagibacter ubique is a lean machine stripped down to the bare essentials for life.Humans have around 30,000 genes that determine everything from our eye colour to our sex but Pelagibacter has just 1,354, US biologists report in the journal Science. What is more, Pelagibacter has none of the genetic clutter that most genomes have accumulated over time. There are no duplicate gene copies, no viral genes, and no junk DNA. 'Chicken soup'The spareness of its genome is related to its frugal lifestyle. The shorter the length of DNA that needs to be copied each generation, the...

    A USC oceanographer's long-term study shows that the marine food chain depends in large part on atmospheric nitrogen. The finding also demonstrates the oceans' massive absorption of greenhouse gas. A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow? In the process, the study also may help to explain how tons of carbon dioxide disappear into the ocean every day, slowing the progress of global warming. Nitrogen is a building block of life and an essential nutrient for phytoplankton and other aquatic life....

    WASHINGTON - Insects that emerge every 17 years in the eastern United States provide valuable nutrients to forest ecosystems when they die, an ecologist says. The Brood X cicadas emerge from their burrows on a regular cycle, sing to attract a mate and lay eggs before dying on the forest floor. Cicadas cling to a leaf after crawling their way above ground(AP Photo) Last spring, the insects swarmed forests, raising concerns about their effects on the ecosystem. Scientists had noticed forests tended to have higher levels of the nutrient nitrogen in their leaves after cicadas emerged and tree growth tended...

"Given the critical need for nitrogen in food production and the sequential nature of the effects of too much nitrogen, it is imperative that strategies be developed to optimize nitrogen management in food and energy production and in environmental protection," James Galloway of...
