• Droughts could hit aging power plants hard
    on March 26, 2019 at 6:37 pm

    Older power plants with once-through cooling systems generate about a third of all U.S. electricity, but their future generating capacity will be undercut by droughts and rising water temperatures linked to climate change. These impacts would be exacerbated by environmental regulations that limit water use. […]

  • Study finds that income inequality is driving growing income gap between different regions

  • Venus flytrap 'teeth' form a 'horrid prison' for medium-sized prey
    on March 26, 2019 at 6:35 pm

    In "Testing Darwin's Hypothesis about the Wonderful Venus Flytrap: Marginal Spikes Form a 'Horrid Prison' for Moderate-Sized Insect Prey," Alexander L. Davis investigates the importance of marginal spikes, the "teeth" lining the outer edge of the plant's snap traps, in successfully capturing prey. He found that Venus flytraps experience a 90 percent decrease in moderate-sized cricket prey capture success when marginal spikes are removed. This effect disappears, however, for larger prey, […]

    on March 26, 2019 at 6:00 pm

    Pathological infertility is a condition affecting roughly 7 percent of human males, and among those afflicted, 10 to 15 percent are thought to have a genetic cause. However, pinpointing the precise genes responsible for the condition has been difficult due to the extensive number involved in generating and developing sperm cells. […]

  • Facebook is free, but should it count toward GDP anyway?
    on March 26, 2019 at 5:54 pm

    For several decades, gross domestic product (GDP), a sum of the value of purchased goods, has been a ubiquitous yardstick of economic activity. More recently, some observers have suggested that GDP falls short because it doesn't include the value of free online goods such as social media, search engines, maps, videos, and more. […]

  • Researchers unlock the biomechanics of how the Ebola virus attaches to its host cell
    on March 26, 2019 at 5:49 pm

    It was recently reported that the number of Ebola cases in the Democratic Republic of Congo has surpassed 1,000, making it the second-worst outbreak in history after the 2014 outbreak in West Africa in which 29,000 people were infected and more than 11,000 died. This latest milestone is a stark reminder of the urgent need to develop effective prevention and treatment agents for this frequently deadly disease. […]

  • The solid Earth breathes
    on March 26, 2019 at 4:56 pm

    The solid Earth breathes as volcanoes "exhale" gases like carbon dioxide (CO2)—which are essential in regulating global climate—while carbon ultimately from CO2 returns into the deep Earth when oceanic tectonic plates are forced to descend into the mantle at subduction zones. However, the amount of carbon in the sediments and ocean crust that subducts is poorly constrained, as is the fraction of that breaks down in the mantle and contributes to volcanic CO2. […]

  • The sense of water—and nitrogen: Studies uncover genome-wide responses that limit crop growth
    on March 26, 2019 at 4:33 pm

    A team of researchers has tested how each gene within the genome of rice—one of the world's most important staple crops—senses and responds to combinations of water and nutrients. Its findings, published in the journal Nature Communications, potentially point to ways to engineer crops in soils around the world that are currently too dry or lack the nutrients needed to sustain crop growth.

  • Technique uses well-known dye to watch amyloid plaques in the brain
    on March 26, 2019 at 4:28 pm

    While amyloid plaques have long been closely associated with mechanisms driving Alzheimer's disease, visualizing how amyloid proteins assemble continues to prove difficult. The nanometer-sized amyloid fibrils are only a fraction of the size that the best light microscopes are able to resolve. New work repurposing one of the oldest known reagents for amyloid looks to help provide a clearer picture of how fibrils come together. […]

  • Droughts could hit aging power plants hard
    on March 26, 2019 at 4:00 am

    Droughts will pose a much larger threat to U.S. power plants with once-through cooling systems than scientists previously suspected, a Duke University study shows. If surface waters warm 3oC and river flows drop 20 percent, drought-related impacts will account for about 20 percent of all shutdowns or capacity reductions at these plants. Retrofitting the plants with recirculating cooling systems will significantly reduce their vulnerability to costly impacts from both drought and environmental […]

  • Sometimes it's not good to be green
    on March 26, 2019 at 4:00 am
