People affected by autism believe increase is 'real,' not diagnostic

A study found that laypeople's beliefs about the causes of autism differ from medical experts' consensus. Many individuals directly or indirectly affected by autism believe the incidence has increased due to environmental hazards and modern lifestyles, rather than changes in diagnosis practices.

Coaxing injured nerve fibers to regenerate by disabling 'brakes' in the system

A study published in Neuron found that deleting a gene called SOCS3 allows mouse axons to regenerate vigorously after injury. The research suggests that the mTOR pathway and JAK/STAT signaling pathway can be manipulated to promote axon regeneration, potentially leading to improved recovery from brain or spinal cord injuries.
