Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.

Father's diet before conception influences children's health      (via sciencedaily.com)     Original source 

A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.

'Weird' new planet retained atmosphere despite nearby star's relentless radiation      (via sciencedaily.com)     Original source 

A rare exoplanet that should have been stripped down to bare rock by its nearby host star's intense radiation somehow grew a puffy atmosphere instead -- the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments. Nicknamed 'Phoenix' for its ability to survive its red giant star's radiant energy discovered planet illustrates the vast diversity of solar systems and the complexity of planetary evolution -- especially at the end of stars' lives.

Small, but smart: How symbiotic bacteria adapt to big environmental changes      (via sciencedaily.com)     Original source 

Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.
