Microbiologist Karen Guillemin considered many universities when she was searching for her first faculty position 25 years ago. In the end, she came ...

According to this model, sigma (σ) factors bind to RNA polymerase to initiate transcription—the process by which genetic information is copied from DNA to RNA—and then detach after initiation to allow ...

A neuroscientist and assistant professor at the University of Alberta presented his research on the neural mechanisms of ...

"You need those neurons to be functional, and for them to be functional, they need a reliable internal source of clean energy," Sehgal explained. "One of the ways that sleep helps the neurons stay ...

Fruit flies, mice, zebrafish, yeast and the tiny worm C. elegans are model organisms that have carried modern biology on ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

A study published in Nature Ecology and Evolution on February 24, 2026, confirms that animals experience time at speeds dictated by their metabolic rates and ecological demands, with small, ...

Researchers from Brown University and the University of Rochester will lead a multi-institution project to test whether reducing DNA-triggered inflammation can help older adults stay healthier for ...

Researchers have been studying tens of thousands of proteins and even more variations without a yardstick to compare their results.

With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects ...
