  • New magma pathways after giant lateral volcano collapses
    Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Such collapses are rather common events during the evolution of a large volcanic edifice, often with dramatic consequences such as tsunami and volcano explosions. These catastrophic events interact with the magmatic activity of the volcano, as new research suggests.

  • New study shows how cells can be led down non-cancer path
    As cells with a propensity for cancer break down food for energy, they reach a fork in the road: they can either continue energy production as healthy cells, or shift to the energy production profile of cancer cells. In a new study, researchers map out the molecular events that direct cells' energy metabolism down the cancerous path. Their findings could lead to ways to interrupt the process.

  • Study links mutations in notch gene to role in B cell cancers
    In B cell tumors, mutated overactive versions of the Notch protein directly drive the expression of the Myc gene and many other genes that participate in B cell signaling pathways, researchers have found. Myc is a critical gene in governing cell proliferation and survival.
  • Rethinking well-being and sustainability measurements from local to global scales
    A new study suggests that standard ways of measuring well-being and sustainability in communities used by global organizations may be missing critical information and could lead to missteps in management actions. The article suggests alternative and complementary approaches that use indicators grounded in the values of a particular community.
  • Smart birds: Canada geese give hunters the slip by hiding out in Chicago
    It's open season for Canada geese in Illinois from mid-October to mid-January. Unfortunately for hunters, Canada geese are finding a new way to stay out of the line of fire. Rather than being 'sitting ducks' in a rural pond, they're setting up residence in the city. Ornithologists conducted a recent study to try to find out why there were so many Canada geese in Chicago in the winter.

    Exploring the links between diseases and tissue-specific gene activity, geneticists have been able to build a model that constitutes a first step towards the identification of specific sequences in the non-coding genome signalling their pathogenicity in the context of a specific disease. In a second study, they went even further by associating particular disease risks - including schizophrenia, cardiovascular disease and diabetes - to the variability of genome activity in various cell types.

  • These shrews have heads that shrink with the season
    If any part of the body would seem ill equipped to shrink, it would probably be the head and skull. And, yet, researchers have found that the skulls of red-toothed shrews do shrink in anticipation of winter, by up to 20 percent. As spring approaches, their heads grow again to approach their previous size.
  • Resistive memory components the computer industry can't resist

    Even low levels of logging in the Amazon rainforest may lead to great losses in biodiversity, new research has found. The research looked at 34 different plots in the state of Pará -- a focal point for Amazon protection efforts in the last decades. They found that even low levels of logging leaded to negative effects on dung beetle diversity and rates of dung beetle-mediated
  • Scientists warn that saline lakes in dire situation worldwide
    Saline lakes around the world are shrinking in size at alarming rates. But what -- or who -- is to blame? Lakes like Utah's Great Salt Lake, Asia's Aral Sea, the Dead Sea in Jordan and Israel, China's huge Lop Nur and Bolivia's Lake Popo are just a few that are in peril. These lakes and others like them are suffering massive environmental problems according to a group of scientists and water managers.
