Honeybee queens are made not just by royal jelly, but by an entire colony engineering the perfect royal nursery. For years, scientists believed the recipe for creating a honeybee queen was surprisingly simple. Feed an ordinary larva enough royal jelly, and it develops into the colony’s ruler. A new study, however, reveals that becoming a […]
Scientists Discover Hidden Kidney Pathway That Rewrites Biology Textbooks
A surprising finding has revealed that the kidneys may control water retention through an additional pathway beyond the one described in traditional physiology. For decades, biology textbooks have taught that a single hormone, vasopressin, plays the central role in helping the kidneys conserve water and prevent dehydration. Now, researchers at Mayo Clinic have discovered that […]
One Tiny Change May Explain How Viruses Jump From Bats to Humans
Scientists found that one tiny genetic change may determine whether a bat virus stays in bats or becomes a human threat. Most infectious disease outbreaks begin when a virus or other pathogen crosses from animals into people. Many scientists believe that is how the COVID-19 pandemic began, with SARS-CoV-2, the virus responsible for COVID-19, originating […]

The Secret to Healthy Aging May Be More Protein and More Exercise
A new review suggests that many adults could benefit from more protein and more exercise than current public health guidelines recommend. A growing body of research suggests that the health advice many people follow today may only be enough to prevent deficiency, not help them thrive throughout life. A new perspective paper published in Frontiers […]
Scientists Unravel a Century-Old Mystery About Hybrid Male Sterility
A new study identifies a genetic processing failure that leaves hybrid fruit fly males unable to produce sperm. One of evolution’s defining moments occurs when two populations become so genetically different that they can no longer produce fertile offspring together. Even among closely related species that can still mate, their hybrid young often reach adulthood […]
