A new study led by the Harvard Pilgrim Health Care Institute reveals the impact of the COVID-19 pandemic on new physicians, highlighting significant shifts in their job market perceptions, compensation trends, and practice location choices.

Myopia is a refractive error (blurred vision at a given distance) that affects about 30% of the world’s population. This proportion is increasing so quickly that it is estimated it will reach 50% by 2050.

Spinal cord injuries are life-altering, often leaving individuals with severe mobility impairments. While rehabilitation robotics—devices that guide movement during therapy—have improved training for those with spinal cord injuries, their effectiveness remains limited. Without active muscle engagement, robotic-assisted movement alone does not sufficiently retrain the nervous system.

A new study from the University of Nottingham has revealed that poor sleep quality may increase susceptibility to conspiracy beliefs, with depression likely playing a key role in this relationship.

An international clinical trial has identified a medication that can help prevent symptomatic COVID-19 in people exposed within households. The results could be particularly important for families where someone is at high risk of serious complications from the illness.

Birth is one of the most critical moments in a person’s life. During this transition, a baby moves from receiving oxygen through the umbilical cord to breathing on their own. Most of the time this shift happens smoothly, but when something goes wrong the consequences can be devastating.

An international team of scientists has revealed new clues about the neural mechanisms underlying memory formation and recognition in the developing human brain, according to a study published in Science Advances.

Most people are familiar with Pavlovian conditioning, in which a reward-anticipatory behavior follows a reward-predicting stimulus. Behind this mechanism is dopamine released within the striatum, the largest structure of the subcortical basal ganglia, which links motor movements and motivation. Yet it remains unclear exactly what kind of dopamine signal is transmitted to the striatum to cause this behavior in primates.

For days, Ezra Byegarazo lay in an isolation ward, his body wracked with fever and weakness.
