When infection rates rise—or in extreme cases—a pandemic hits, it’s impossible to test everyone. Time, money and resources don’t allow it. So what are the best strategies to track and curb disease outbreaks?

Our immune systems rely on iron to function, but so do invading viruses and bacteria. New research from Binghamton University, State University of New York studying health care workers in Nigeria during COVID, reveals that very early in the arms race—when an infectious disease is emerging and still very new to humans—iron nutrition tradeoffs are in play.

Northwestern University researchers have tested a method to reduce the dreaded nocturnal itch-scratch cycle. Using an AI-trained wearable sensor with vibrating feedback, the device significantly reduced nocturnal scratching in adults with mild atopic dermatitis. The small trial demonstrated a decrease in scratching events and duration without impacting total sleep opportunity.

Who hasn’t been there? The big meal is over, you’re full, but the craving for sweets remains. Researchers from the Max Planck Institute for Metabolism Research have now discovered that what we call the “dessert stomach” is rooted in the brain. The same nerve cells that make us feel full after a meal are also responsible for our craving for sweets afterwards.

Adults with a history of depression gain long-term physical conditions around 30% faster than those without, according to research published February 13 in the open-access journal PLOS Medicine.

A new study led by researchers at UF Health has uncovered why males and females may experience stress differently, providing crucial insights into how the brain’s molecular mechanisms adapt to acute challenges.

Neuroscientists have new insights into why previous experiences influence future behaviors. Experiments in mice reveal that personal history, especially stressful events, influences how the brain processes whether something is positive or negative. These calculations ultimately impact how motivated a rodent is to seek social interaction or other kinds of rewards.

In the opening scene of Love, Actually, Hugh Grant’s character says how, whenever he gets gloomy with the state of the world, he thinks about the arrivals gate at Heathrow airport. The reason is on screen: we see couples kissing, old friends embracing, children smiling and laughing as they jump into the arms of their parents.

Venous thromboembolism (VTE) risk varies across hormonal contraceptives, according to a research letter published online Feb. 10 in the Journal of the American Medical Association.

Researchers provided a long-awaited and rare genetic diagnosis in a child with Lennox-Gastaut syndrome, a type of developmental epileptic encephalopathy (DEE), associated with a severe, complex form of epilepsy and developmental delay.
