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 […]

1.4-Million-Year-Old Footprints Reveal a Giant Human Relative
A 1.4-million-year-old trail of footprints reveals that a powerful human relative grew nearly as large as us and may have traveled in all-male groups. Eight individuals walked across the wet ground beside an ancient Kenyan lake. Within a short time, sediment buried their footprints and preserved a scene that would remain hidden for roughly 1.4 […]
Rocks From the Moon’s Far Side Are Rewriting Lunar History
The Moon’s far side is overturning a long-held theory, revealing that the early Solar System’s asteroid assault may have faded slowly instead of exploding in one catastrophic burst. For decades, scientists have debated whether the early Solar System endured one sudden, catastrophic wave of asteroid strikes or a much longer period of gradually fading violence. […]
