New research finds ketogenic diet-induced high cholesterol does not predict heart disease

The Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center, in collaboration with researchers across multiple institutions, has published a new study that challenges the long-held belief that high cholesterol correlates and even directly causes coronary artery disease, or plaque buildup in the arteries in metabolically healthy individuals.

Letting your mind wander can sometimes improve learning, research suggests

When people let their minds wander during tasks that require attention and active thinking, it can hurt how well they learn and perform the tasks. But there are more passive kinds of learning that require less attention. Péter Simor, from Eötvös Loránd University, and colleagues explored how mind wandering influences learning in tasks requiring little attention in their paper published in The Journal of Neuroscience.

Global study supports the immunity debt hypothesis for flu after COVID restrictions

The COVID-19 pandemic led many countries around the world to implement strict public health measures like lockdowns, social distancing, mask wearing, and travel restrictions. While these steps were crucial and effective in controlling the spread of COVID-19, they also had an additional effect—a dramatic drop in cases of other illnesses like influenza (flu) and respiratory viruses.

Biomarkers help predict treatment success for parasitic skin disease

Nearly one million people worldwide are plagued annually by cutaneous leishmaniasis, a devastating skin infection caused by the Leishmania parasite. Predominantly affecting vulnerable populations in tropical and subtropical regions like North Africa and South America, this disease thrives in areas marked by malnutrition, poor housing and population displacement. Left untreated, it can lead to lifelong scars, debilitating disability and deep social stigma. Despite its global impact, there is no vaccine—and existing treatments are ineffective, toxic and difficult to administer.

Perceiving one’s own body—scientists discover babies can sense their heartbeat and breathing

Body signals such as heartbeat and breathing accompany us constantly, often unnoticed as background noise of our perception. Even in the earliest years of life, these signals are important as they contribute to the development of self-awareness and identity. However, until now, little has been known about whether and how babies can perceive their own body signals.
