Breast cancer is the most common cancer in women worldwide. The immune system plays a crucial role in determining outcomes. Triple-negative breast cancer (TNBC) is the most lethal subtype, disproportionately affecting ethnic minorities and those with lower socioeconomic status. Despite advances in therapy, TNBC has inferior outcomes compared to non-triple-negative…

Ancient DNA preserved in the tooth tartar of human fossils encodes microbial metabolites that could be the next antibiotic. Credit: Werner/Siemens Foundation Microorganisms—in particular bacteria—are skillful chemists that can produce an impressive diversity of chemical compounds known as natural products. These metabolites provide the microbes major evolutionary advantages, such as…

Bacteria have lived on our planet earth for about 3 billion years, most of the 4.5 billion years that the planet has been around. And while the industrious microbes are central to medicine, disease and most areas of the natural world, we understand little about the form they took in…

Experts found no evidence that continuing antibiotics after a patient's incision has been closed, even if it has drains, prevents surgical…

Mike Perry needs antibiotics after his star-making turn at BKFC 41. But you should see the other guy. Perry not only shattered Luke Rockhold’s front teeth at this past Saturday’s pay-per-view event, he knew the moment he did it. “I felt that in my fist, his teeth went into it,…

Health Bacteria are more susceptible to antibiotics when they can't produce fatty acids, suggesting that drugs inhibiting this process could help us overcome antibiotic resistance By Grace Wade A drug combination can treat antibiotic-resistant bacteria Kateryna Kon/Shutterstock Pairing antibiotics with drugs that prevent bacteria from producing fatty acids may help…

Experts say sloths appear to be infection resistant. The fur of Costa Rican sloths appears to harbor antibiotic-producing bacteria that scientists hope may hold a solution to the growing problem of "superbugs" resistant to humanity's dwindling arsenal of drugs. Sloth fur, research has found, hosts bustling communities of insects, algae,…

A new test revealed that FDA-approved antibiotics -- available at your neighborhood pharmacy -- can effectively treat superbugs. They are not prescribed, however, because the gold-standard test predicts they will not work. The new test may improve the way antibiotics are developed, tested and prescribed -- and it is openly…

Solving a riddle that has confounded biologists since bacterial spores -- inert, sleeping bacteria -- were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly…
