• ERKs got rhythm: Protein that controls cell growth found to cycle in and out of cell nucleus

  
  Biology News Net — Authority: 434
  Time-lapsed video of individual breast tissue cells reveals a never-before-seen event in the life of a cell: a protein that cycles between two major compartments in the cell. The results give researchers a more complete view of the internal signals that cause breast tissue cells to grow, events that go awry in cancer ...

• A smorgasbord of fluorescent proteins

  
  Bench Marks — Authority: 110
  Live cell imaging techniques are driving a revolution in biological research. Instead of viewing dead tissues and cells fixed at a particular stage of activity, scientists can now visualize dynamic changes as they happen, permitting a better understanding of complete processes. The revolution has been fueled by the ...

• Cells defend themselves from viruses, bacteria with armor of protein errors

  
  Biology News Net — Authority: 434
  When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.

• Polyphenols and polyunsaturated fatty acids boost the birth of new neurons

  
  Biology News Net — Authority: 434
  Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brains stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells. The research ...

• Pushing the brain to find new pathways

  
  Biology News Net — Authority: 434
  Until recently, scientists believed that, following a stroke, a patient had about six months to regain any lost function. After that, patients would be forced to compensate for the lost function by focusing on their remaining abilities. Although this belief has been refuted, a University of Missouri occupational ...

• Chromosomes dance and pair up on the nuclear membrane

  
  Biology News Net — Authority: 434
  Meiosis – the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell – is a major crossroads in all organisms reproducing sexually. Yet, how the cell precisely choreographs these chromosomal interactions is a long-standing question.
