From lucky tokens that keep instruments running smoothly to a weekly cookie break, scientists told us about their favorite lab customs and beliefs.

Studying the genetics and neural mechanisms behind sneezing induced by bright light can help scientists better understand neural circuits in the brain.

Bacteria made of mirror molecules could evade the immune system and outcompete native species, but strategies put in place now could prevent this outcome.

Light can affect mood through the body’s internal clock. But the relationship between light, seasonal changes, and emotions is not that simple.

The reds, purples, and greens of a bruise aren’t just random; they reveal a biological timeline that can vary widely among people.

Nearly 5,000 people sampled their pets’ DNA to help scientists understand complex traits in the animals, providing insights into cat, dog, and human health.

At the intersection of biology and computation, this postdoc studies how nanoscale protein shells control the flow of life’s essential molecules.

From the challenges of moving abroad to the thrill of discovery, this postdoc's journey highlights resilience, collaboration, and the power of new technologies.

The need for sleep likely evolved to get rid of toxic molecules from the mitochondria, a landmark study shows using sleep-deprived flies.

Researchers modified a protein in the cell elimination pathway to create a targeted system for destroying disease-causing cells, called Crunch.

Sucralose can weaken patients’ response to cancer treatment. The gut microbiome likely mediates this effect, further studies in mice show.
