Hidden Primed Step in Nerve-Muscle Communication Found

An international research team has mapped the millisecond-by-millisecond process by which nerve signals activate muscles, uncovering a previously unseen “primed” intermediate step. This breakthrough reveals that neuromuscular receptors move asynchronously—not in perfect unison as scientists long believed—redefining how communication between nerves and muscles is understood.

Serotonin Neurons Challenge Old Views of Brain Function

Serotonin neurons in the brainstem are not independent, as once thought, but interact to influence decision-making. Researchers found that clusters of serotonin neurons compete and collaborate, shaping when and how serotonin is released throughout the brain.

Serotonin Helps Your Brain Predict Future Rewards

New research reveals that serotonin plays a key role in how the brain predicts future rewards, shedding light on its puzzling activity in response to both pleasure and pain. Scientists found that serotonin neurons encode a “prospective code for value,” signaling expectations about upcoming outcomes and how rapidly those expectations are changing.

Serotonin Signals the Brain’s Best Guess About Future Rewards

A new study reveals that serotonin neurons in the brain may play a crucial role in helping us estimate the value of future rewards. Rather than simply responding to pleasure or pain, serotonin appears to encode a "prospective value" signal—telling the brain how good the near future is likely to be.

Stem Cells in the Brain Use Childlike Signals to Trigger Regeneration

Scientists have discovered that neural stem cells (NSCs) receive constant feedback from their daughter cells, influencing whether they remain dormant or activate to form new neurons and glia. This parent-child relationship helps regulate brain regeneration and repair.

New Research Provides Theory on Why Women Stopped Menstruating Upon Arrival at Nazi Death Camps

98% of women imprisoned in Nazi concentration camps during the Holocaust experienced amenorrhea, or the absence of menstruation. A new theory proposes the sudden cessation of menstruation of these women was too uniform to be the effect of trauma and malnutrition alone, but rather caused by the administration of synthetic steroids in their food supply that halted menstruation and impaired the ability to produce children.
