• Uncovering secrets of elastin's flexibility during assembly

  05-02-2016 20:00
  
  Elastin is a crucial building block in our bodies - its flexibility allows skin to stretch and twist, blood vessels to expand and relax with every heartbeat, and lungs to swell and contract with each breath. But exactly how this protein-based tissue achieves this flexibility remained an unsolved question - until now.

• Chromosomes reconfigure as cell division ends

  05-02-2016 20:00
  
  Cellular senescence—when a cell can no longer divide—is a programmed stage in a cell's life cycle. Sometimes, as in aging, we wish it didn't happen so much and sometimes, as in cancer, we wish it would happen more. Given its important impacts on health, biologists wish they could explain more about what's happening in cells when senescence takes hold. A new study helps by showing that chromosomes become somewhat transformed, altering their patterns of gene expression.

• 'Cannibalism' between stars: New research shows the turbulent past of our sun

  05-02-2016 20:00
  
  Stars are born inside a rotating cloud of interstellar gas and dust, which contracts to stellar densities thanks to its own gravity. Before finding itself on the star, however, most of the cloud lands onto a circumstellar disk forming around the star owing to conservation of angular momentum.The manner in which the material is transported through the disk onto the star, causing the star to grow in mass, has recently become a major research topic in astrophysics.

• Super-resolution microscope allows visualization of the mechanism that maintains cell polarity

  05-02-2016 15:00
  
  Cells are not uniform spheres; they generally come in a variety of disparate shapes. In the broadest sense, this variation in shapes is known as cell polarity, and it is an essential property for a variety of cell functions. Growth in accordance with their polarity allows cells to shape themselves in forms appropriate to their function. It has been found that the establishment and maintenance of polarity is governed by the interdependent relationship between the polarity marker protein on the pl
