Marsupials key to discovering the origin of heater organs in mammals      (via sciencedaily.com)     Original source 

Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.

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.

Early summer fishing can have an evolutionary impact, resulting in smaller salmon      (via sciencedaily.com)     Original source 

A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.

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.

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.
