Sleep Deprivation in children affects brain myelin development

Sleep is vital for humans. If adults remain awake for longer than usual, the brain responds with an increased need for deep sleep. In adults, these deep-sleep waves are most pronounced in the prefrontal cortex – the brain region which plans and controls actions, solves problems and is involved in the working memory. Sleep deprivation …

Understanding roundworm nerve regeneration mechanism and its molecular pathways could help nerve injury treatment.

Certain types of nerve injury, such as those from automobile accidents and falls, can damage or sever the axons that connect neurons and allow them to communicate with each other. Although axons elsewhere in the body can regenerate to some extent after such damage, those in nerves are far less capable, resulting in long-lasting or …

Researchers mapped the signaling processes used by Insulin in Fruit flies.

Fruit flies may be small, but the genetic secrets they can unlock for humans are many. In the current issue of the journal Development, Michigan State University researchers mapped the signaling processes used by insulin in fruit flies. The significance of the discovery in the tiny Drosophila melanogaster, which have been called “Tiny people with …

Role of TB specific antibodies in Tuberculosis infection found

A study led by investigators from the Ragon Institute of MGH, MIT, and Harvard finds evidence that antibody protection may help control infection with the bacteria that causes tuberculosis. In their study receiving online publication in Cell, the research team describes finding consistent differences in both the structure and function of antibodies targeting the TB …
