A tiny coffee pest may be building the perfect hideout for its own predators. Coffee berry borers tunnel deep into coffee fruit, where they feed and reproduce beyond the reach of many predators. But after tiny ants force the beetles out, some species appear to claim the abandoned chambers as nurseries for their young. Jonathan […]
Coffee’s Most Destructive Pest Is Accidentally Helping the Ants That Hunt It
A tiny coffee pest may be building the perfect hideout for its own predators. Coffee berry borers tunnel deep into coffee fruit, where they feed and reproduce beyond the reach of many predators. But after tiny ants force the beetles out, some species appear to claim the abandoned chambers as nurseries for their young. Jonathan […]
Cells Join Forces To Survive Prolonged Mechanical Strain
When tissues are stretched for hours, their cells rebuild their internal support system. A cell’s nucleus is usually anchored inside a protective web of protein fibers. But when tissue remains stretched for hours, that arrangement can break apart. Researchers have discovered that epithelial cells respond to prolonged strain by rebuilding their internal skeleton across entire […]
When Gut Bacteria Run Out of Fiber, They May Start Eating You
When plant nutrients run low, some gut bacteria may turn on their host and begin consuming the intestines’ protective lining. The health effects of a plant-based diet may depend not only on what gut bacteria eat but also on whether they begin feeding on the gut itself. New research suggests that fiber and previously overlooked […]
Scientists Discover the Brain May Enter a New Biological Phase Between 50 and 75
A single-cell study reveals major changes in immune cells, genome organization, and gene regulation within the aging human hippocampus, offering important insights into brain aging and dementias associated with age. Between roughly ages 50 and 75, the cellular landscape of the human hippocampus begins to shift. Immune cells change, the genome’s physical organization weakens, and […]

Is Sparkling Water Bad for Your Teeth? A New Study Has Answers
A study found that unsweetened sparkling water lowers oral pH less than soda sweetened with sugar. A sip of sparkling water briefly makes the mouth more acidic, but not nearly as much as sugar-sweetened soda, according to a comparison of several common beverages. The findings suggest that choosing an unsweetened carbonated drink instead of soda […]
Scientists Discover an Odd Genetic Trait in an Ancient Aboriginal Food Plant
A native Australian millet may carry the genetic fingerprints of thousands of years of Aboriginal harvesting, storage, and plant management. Seen from the air, Channel Country resembles a vibrant and vast tapestry, with a network of waterways crisscrossing the land. Spread across more than 280,000 square kilometers in outback Australia, it is one of the […]
