  • Source - The tiny hairs found on plant roots play a pivotal role in helping reduce soil erosion, a new study has found. The research, led by the University of Bristol and published inCommunications Biology, provides compelling evidence that when root hairs interact with the surrounding soil they reduce soil erosion and increase soil cohesion by binding soil particles.
  • Source - Researchers at the Max Planck Institute of Neurobiology are the first to describe different emotional facial expressions for mice. Similar to humans, the face of a mouse looks completely different when it tastes something sweet or bitter, or when it becomes anxious. With this new possibility to render the emotions of mice measurable, neurobiologists can now investigate the basic mechanisms of how...
  • Source - Newly discovered single-celled creatures living deep beneath the seafloor have given researchers clues about how they might find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers persisted over a decade of trial and error to find a new way to examine the rocks.
  • Source - Experts have been unable to explain why cells from bacteria to humans leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites -- substances involved in the chemical processes to sustain life with production of complex molecules and energy -- may provide cells both selfish and selfless benefits.
  • Source - University of Bayreuth researchers, together with scientists from Italy and China, have for the first time systematically investigated under which conditions, and to what extent,...
