• Study finds less gloomy outlook for subtropical rainfall

  14-11-2016 22:53
  
  A new study found that rainfall over land in the subtropics - including in the southeastern U.S. - will not decline as much as it does over oceans in response to increased greenhouse gases. The study challenges our previous understanding of the drying that will occur in subtropical regions and suggests its impact on people living in these regions could be less severe than initially thought.

• Mississippi River could leave farmland stranded

  14-11-2016 22:08
  
  If the Mississippi River continues to go unchecked, the farmland on Dogtooth Bend peninsula may be only accessible by boat. According to a University of Illinois study, each successive flood carves a deeper channel across the narrow neck of the peninsula. This floodwater shortcut threatens to permanently reroute the Mississippi River, leaving Dogtooth Bend an island rather than a peninsula.

  They're in stain-resistant carpet, paint, permanent markers, food packaging and firefighting foam. Perfluorinated compounds (PFCs), a broad class of manufactured chemicals, touch every corner of the industrialized world. They're impervious to traditional remediation strategies, and when they're ingested in large quantities, like in contaminated drinking water, they may be dangerous to human health.

  14-11-2016 21:00
  
  A research team led by Christa Schleper from the University of Vienna succeeded in isolating the first ammonia-oxidizing archaeon from soil: Nitrososphaera viennensis—the 'spherical ammonia oxidizer from Vienna.' In the current issue of the journal PNAS, the scientists present new results: they were able to detect all proteins that are active during ammonia oxidation—another important piece of the puzzle for the elucidation of the energy metabolism of Archaea.

• Study finds limited sign of soil adaptation to climate warming

  14-11-2016 21:00
  
  While scientists and policy experts debate the impacts of global warming, the Earth's soil is releasing roughly nine times more carbon dioxide to the atmosphere than all human activities combined. This huge carbon flux from soil—due to the natural respiration of soil microbes and plant roots—begs one of the central questions in climate change science. As the global climate warms, will soil respiration rates increase, adding even more carbon dioxide to the atmosphere and accelerating

• Not without my microbiome: Legume-rhizobia symbiosis influences bacterial community in plant roots

  14-11-2016 21:00
  
  Some plants can meet their nitrogen requirements by obtaining it from the atmosphere. To do this, they use bacteria in their roots, with which they establish a symbiotic relationship. Paul Schulze-Lefert's Research Group at the Max Planck Institute for Plant Breeding Research in Cologne and Simona Radutoiu from Aarhus University in Denmark have investigated the microbial communities in and around the roots of these plants. They discovered that the absence of legume-rhizobia symbiosis causes dras

• NASA finds unusual origins of high-energy electrons

  14-11-2016 20:25
  
  High above the surface, Earth's magnetic field constantly deflects incoming supersonic particles from the sun. These particles are disturbed in regions just outside of Earth's magnetic field - and some are reflected into a turbulent region called the foreshock. New observations from NASA's THEMIS mission show that this turbulent region can accelerate electrons up to speeds approaching the speed of light. Such extremely fast particles have been observed in near-Earth space and many other places i

  Nature is full of parasites—organisms that flourish and proliferate at the expense of another species. Surprisingly, these same competing roles of parasite and host can be found in the microscopic molecular world of the cell. A new study by two Illinois researchers has demonstrated that dynamic elements within the human genome interact with each other in a way that strongly resembles the patterns seen in populations of predators and prey.
