An estimated 38 trillion bacteria live in the human body—and only a small fraction are harmful to our health. However, the harmful ones can cause serious illness, especially when they develop resistance to antibiotics.
Researchers have figured out a missing piece of the puzzle of how human cells detect invading viruses and mount an immune response within an hour.
Scientists have often thought of cells as small, bustling cities with parts that resemble factories, power grids and shipping systems. While past research has illuminated the individual components of these cell cities, scientists ...
For many years, antibiotics have been added to animal feed to help control harmful bacteria and improve growth. But amid concerns about antibiotic resistance—when bacteria adapt to survive treatments that would normally kill ...
Scientists at Cornell University have found a human genetic element in a poxvirus and discovered that it is both an important gene for brain function and a jumping gene capable of moving and inserting itself into genomes. ...
Humans and domesticated animals have lived together for millennia, and this relationship has shaped their destinies in countless ways. Animals offered people food, companionship, traction (pulling plows), clothing and transportation.
A new tool to mutate bacteriophages—viruses that infect bacteria—provides a "big leap" forward in our understanding of how they function and our ability to harness their full potential.
A cell's ability to repair its damaged DNA is one of the most fundamental processes in biology, helping protect us from diseases like cancer. Over the years, researchers have unraveled many of the mechanisms cells use to ...
About 66 million years ago, the asteroid that ended the age of the dinosaurs paved the way for a spectacular expansion of new animal species. During this period, ants rose to ecological dominance. Today, they form the largest ...
In the first detailed chromosome map of the aardwolf, Texas A&M University researchers have discovered that, despite millions of years of separate evolution, the chromosomes of aardwolves, other hyenas and even domestic cats ...
