Health News: Gut damage identified as cause of vaccine failure ♦ Body clock study unlocks prospect of treatment for osteoarthritis ♦ When rejection comes from within

Gut damage identified as cause of vaccine failure, malnutrition Damage to the gut from infections is causing vaccine failure and contributing to malnutrition in low-income countries, researchers have determined. Research in Bangladesh sheds light on why: damage to the gut from infection, say researchers, explains why food alone is not a solution to malnutrition. To be effective, nutritional therapy will need to include measures to prevent or treat the damage to the gut of infants.
Body clock study unlocks prospect of treatment for osteoarthritis A biologist has, for the first time, established that the painful and debilitating symptoms endured by osteoarthritis sufferers are intrinsically linked to the human body clock.
Scientists say face mites evolved alongside humans since the dawn of human origins A landmark new study explores the fascinating, little-known natural history of the face mite species Demodex folliculorum, using genetic testing to link the microscopic animal's evolution to our own ever-evolving human story. By zooming in on mite mitochondrial DNA from around the world, scientists discovered that different human populations have different mites, that those mites follow families through generations, and that they are not casually transferred between humans.
When rejection comes from within A new cellular structure responsible for previously unexplained rejection of organ transplants has been identified. This discovery could one day revolutionize transplantation practice by modifying risk assessment of rejection in people who receive heart, lung, kidney, or liver transplants
