Dolphin mothers modify their signature whistles when communicating with their calves increasing the maximum frequency, or pitch, similar to human caregivers using a higher-pitched voice communicating with young children—"motherese." buff.ly/WbGvZrC

The brain is not simply overwhelmed by chronic pain, It actively tries to regulate emotional well-being, when regulatory system remains balanced, people stay resilient, when disrupted, particularly by inflammation in the hippocampus, depression can emerge. buff.ly/QgfySl6

Amyloid beta in large amounts and tau proteins compete for the same binding sites on microtubules in neurons, displacement of tau by amyloid beta, rather than aggregation of either protein, may be primary driver of Alzheimer's disease pathology buff.ly/gMSZGx4
