• Scientists recreate life’s first step: Linking amino acids to RNA August 28, 2025
  Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This finding bridges the “RNA world” and “thioester world” theories and suggests how life’s earliest peptides may have formed.
• A tiny chip may have solved one of clean energy’s biggest problems August 28, 2025
  In just one afternoon, scientists used a nanoparticle “megalibrary” to find a catalyst that matches or exceeds iridium’s performance in hydrogen fuel production, at a fraction of the cost.
• This simple diet could help protect memory, even with Alzheimer’s genes August 28, 2025
  A Mediterranean-style diet was linked to lower dementia risk, especially in people with high-risk Alzheimer’s genes. The strongest benefits were seen in those with two APOE4 copies, showing diet may help offset genetic vulnerability. Researchers say food may influence key metabolic pathways that protect memory and cognitive function.
• Butterfly nebula reveals sparkling gems, fiery dust, and the ingredients of life August 28, 2025
  James Webb has revealed that the Butterfly Nebula hides a complex mix of gemstone-like crystals, fiery dust, and unexpected carbon molecules. The discovery may rewrite how we understand the chemistry that seeds planets and life itself.
• Why most whale sharks in Indonesia are scarred by humans August 28, 2025
  Whale sharks in Indonesia are suffering widespread injuries, with a majority scarred by human activity. Researchers found bagans and boats to be the biggest threats, especially as shark tourism grows. Protecting these gentle giants may be as simple as redesigning fishing gear and boat equipment.
