Understanding the expanded role of clinical ethicists
The COVID-19 pandemic brought many troubling ethical issues to the frontlines of clinical care, creating significant distress for clinicians, patients, and families. Behind the scenes, clinical ethicists managed those issues to support front-line worke…
Brain bubbles: Researchers describe the dynamics of cavitation in soft porous material
A tiny bubble popping within a liquid seems more fanciful than traumatic. But millions of popping vapor bubbles can cause significant damage to rigid structures like boat propellers or bridge supports. Can you imagine the damage such bubbles could do t…
Beyond neurons: How cells called astrocytes contribute to brain disorders
Star-shaped cells called astrocytes may bear the brunt of the responsibility for exacerbating the symptoms of some neurodevelopmental disorders. Scientists have now identified a molecule produced by astrocytes that interferes with normal neuron develop…
Wildlife hunting motivations vary across Africa and Europe
Wildlife hunting motivations and resulting ecological consequences vary depending on the socio-economic context across Africa and Europe, according to a new study. Despite these shifts, the intensity of hunting varies less than commonly expected across…
