  • Ocean Heat Content Reveals Secrets of Fish Migration Behaviors

    Researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science developed a new method to estimate fish movements using ocean heat content images, a dataset commonly used in hurricane intensity forecasting. With Atlantic tarpon as the messenger, this is the first study to quantitatively show that large migratory fishes, such as…

  • How will rising sea levels impact the Phillippines?

    More than 167,000 hectares of coastland — about 0.6% of the country's total area — are projected to go underwater in the Philippines, especially in low-lying island communities, according to research by the University of the Philippines.Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming.…

  • The fish that cools off by jumping OUT of the water

    On hot, humid days, you might jump into water to cool down, but for the tiny mangrove rivulus fish, cooling down means jumping out of water, according to a new study from the University of Guelph.In the study published today in the journal Biology Letters, the researchers describe how these fish air-chill themselves on solid ground in order…

  • Dirty pipeline: Methane from fracking sites can flow to abandoned wells, new study shows

    As debate roils over EPA regulations proposed this month limiting the release of the potent greenhouse gas methane during fracking operations, a new University of Vermont study funded by the National Science Foundation shows that abandoned oil and gas wells near fracking sites can be conduits for methane escape not currently being measured.The study, to…

  • NASA studies LA earthquake

    A new NASA-led analysis of a moderate magnitude 5.1 earthquake that shook Greater Los Angeles in 2014 finds that the earthquake deformed Earth's crust across a broad region encompassing the northern Los Angeles Basin and northern Orange County. The shallow ground movements observed from this earthquake likely reflect strain accumulated on deeper faults, which remain…

  • Heavy rain doesn't mean more trees in African savanna

    In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem's high annual precipitation would result in greater tree growth. Yet a 2011 study found that the more instances…

  • Why more rain leads to fewer trees in the African savanna

    In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem's high annual precipitation would result in greater tree growth. Yet a 2011 study found that the more instances…

  • Mice stutter too

    About 70 million people worldwide stutter when they speak, and it turns out humans aren’t the only ones susceptible to verbal hiccups. Scientists at this year’s Society for Neuroscience Conference in Chicago, Illinois, show that mice, too, can stumble in their vocalizations. In humans, stuttering has long been linked to a mutation in the “housekeeping”…

  • Bees don't like diesels!

    Diesel fumes may be reducing the availability of almost half the most common flower odours that bees use to find their food, new research has found.The new findings suggest that toxic nitrous oxide (NOx) in diesel exhausts could be having an even greater effect on bees’ ability to smell out flowers than was previously thought.NOx is a…

  • “Good” cholesterol may not be so good after all for older women

    Researchers in the United States have found that hormonal changes in women during the menopause can cause so-called ‘good cholesterol’ to become dangerous to their health. EurActiv France reports. 'Good cholesterol' usually protects the arteries by helping to transport 'bad cholesterol' to the liver to be processed. But recent research in the United States suggests that the risk…
