The Field Narrows For Cover Crops In Biofuel Production
Scientists are looking for cover crop perennials that provide the best balance in biofuel production between agronomic success and environmental sustainability. Mussels Evolve Quickly To Defend Against Invasive Crabs
Scientists at the University of New Hampshire (UNH) have found that invasive crab species may precipitate evolutionary change in blue mussels in as little as 15 years. The study, by UNH graduate student Aaren Freeman with Associate Professor of Zoology James Byers, and published in the Aug. 11 issue of the journal Science, indicates that such a response can evolve in an evolutionary nanosecond compared to the thousands of years previously assumed. Mass extinction: Why did half of N. America's large mammals disappear
Years of scientific debate over the extinction of ancient species in North America have yielded many theories. However, new findings reveal that a mass extinction occurred in a geological instant. New USGS Oil &Gas Assessment Of Central North Slope, Alaska
A U.S. Geological Survey (USGS) assessment of undiscovered oil and gas resources of the central part of the Alaska North Slope and the adjacent state offshore area finds that there is a significant amount of oil and a large amount of gas that remains to be discovered. The assessment estimates that there are 4.0 billion barrels of oil (BBO), 37.5 trillion cubic feet (TCF) of natural gas, and 478 million barrels of natural gas liquids that are undiscovered and technically recoverable. Grape expectations controversy to put you to sleep
Certain Italian grape varieties used in popular red wines may contain high levels of the sleep hormone melatonin, according to an analysis by Marcello Iriti, Mara Rossoni, and Franco Faoro at the University of Milan. However, a melatonin expert in the US is unconvinced by the results citing the undefinitive nature of the analytical procedures [...] Say Again? Speakers Can Avoid Confusion For Listeners, Researchers Fin
People often fail to avoid ambiguities when they speak. Previous research has shown that speakers choose their sentences based, in part, on how easy those sentences are to produce for themselves while not taking ease of comprehension into account. An ambiguous phrase is often easier to construct than an unambiguous one, so some people will speak ambiguously even if they are likely to be misunderstood. Biofuels vs Fossil Fuels
Biofuels are not much better than fossil fuels in terms of the impact on atmospheric pollution levels and effects on climate change, according to Mark Jacobson professor of civil and environmental engineering at Stanford University. This is especially true when making claims about the sustainability of biofuels in comparison with hydrogen fuel cells and battery-driven [...]Biofuels vs Fossil Fuels is a post from: Sciencebase Science Blog Battling Bitter Coffee: Chemists Identify Roasting As The Main Culprit
Bitter taste can ruin a cup of coffee. Now, chemists say they have identified the chemicals that appear to be largely responsible for java's bitterness, a finding that could one day lead to a better tasting brew. Research by others over the past few years has identified an estimated 25 to 30 compounds that could contribute to the perceived bitterness of coffee. But the main cause of coffee bitterness has remained largely unexplored until now. According to a new study, roasting is the key factor. Ceramic Microreactors Developed For On-site Hydrogen Production
Scientists at the University of Illinois at Urbana-Champaign have designed and built ceramic microreactors for the on-site reforming of hydrocarbon fuels, such as propane, into hydrogen for use in fuel cells and other portable power sources.Applications include power supplies for small appliances and laptop computers, and on-site rechargers for battery packs used by the military. The Hidden Gulag: Exposing North Korea's Prison Camps
This report relies on expert analysis, satellite photographs, and stories provided by former prisoners to document the repression of North Korea's "forced-labor colonies, camps, and prisons where scores of thousands of prisoners -- some political, some convicted felons -- are worked, many to their deaths, in mining, logging, farming, and industrial enterprises."From the U.S. Committee for Human Rights in North Korea, a "bi-partisan, not-for-profit human rights organization."
