In the last two decades or so, though, researchers have found that these viruses can jump between animal and human hosts. In recent years, coronaviruses have caused lethal outbreaks of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome […]

A simple trick for modeling calcium

Calcium ions enable cells to communicate with one another, allowing neurons to interact, muscles to contract, and the heart’s muscle cells to synchronize and beat. To better understand these processes, researchers often use computer simulations, but accurate models are challenging and computationally expensive. Researchers demonstrate how a straightforward modification in a computer model leads to […]

People with major depressive disorder (MDD) feel more negative emotion when remembering painful experiences than people without the disorder, according to a new study.
