Scientists discover the mathematical rules underpinning brain growth

Life is rife with patterns. It’s common for living things to create a repeating series of similar features as they grow: think of feathers that vary slightly in length on a bird’s wing or shorter and longer petals on a rose. It turns out the brain is no different. By […]

Mapping Bacterial Neighborhoods in the Gut

The microscopic populations of bacteria in our intestines are, in some ways, just like us: They live in communities, eat, work, reproduce, and eventually die. Many of these bacterial species live in harmony with our bodies, providing benefits to us in exchange for nutrients and shelter. When the right kinds […]

Cellular SOS: CRISPR Technique Reveals How Cell’s ‘Power Plants’ Activate Emergency Response

The integrated stress response (ISR) is a well-studied biological circuit that behaves like a disaster response center: it takes control when something in the cell goes awry. When the ISR receives a distress signal, it responds by reallocating cellular resources. Run-of-the-mill cellular functions are shut off so that valuable resources […]

Throat Cancers Are on the Rise: Why This Matters to You

Who among us hasn’t had a sore throat, a hoarse voice or a lump in the neck? Usually, these are minor problems that go away on their own or after a course of antibiotics—but if they don’t, check in with your doctor. These can all be signs of oropharyngeal cancer […]

Microscopic STAR Particles Offer New Potential Treatment for Skin Diseases

Skin diseases affect half of the world’s population, but many treatments are not effective, require frequent injections, or cause significant side effects. But what if there was a treatment that eliminated injections, reduced side effects, and increased drug effectiveness? A skin therapy with these properties may be on the horizon […]

Cancerous tumors, surrounding cells illuminated by new imaging agent

Scientists at Washington University School of Medicine in St. Louis have developed a new imaging agent that could let doctors identify not only multiple types of tumors but the surrounding normal cells that cancer takes over and uses as a shield to protect itself from attempts to destroy it. The […]
