• Why so many young kids with ADHD are getting the wrong treatment September 16, 2025
  Preschoolers with ADHD are often given medication right after diagnosis, against medical guidelines that recommend starting with behavioral therapy. Limited access to therapy and physician pressures drive early prescribing, despite risks and reduced effectiveness in young children.
• Strange ‘leopard spots’ in a Mars rock could be the strongest hint of life yet September 16, 2025
  NASA’s Perseverance rover has delivered its most compelling clue yet in the search for life on Mars. A rock sample called “Sapphire Canyon,” taken from the Bright Angel formation in Jezero Crater, shows unusual mineral patterns known as “leopard spots” that may have formed through microbial activity. While non-biological processes could also explain the find, […]
• Stress measured in hair could predict depression and anxiety in children September 16, 2025
  Researchers from the University of Waterloo discovered that measuring long-term stress through children’s hair samples can reveal early signs of mental health risks in those living with chronic physical illnesses. Children with persistently high cortisol were more likely to struggle with anxiety, depression, and behavioral challenges, while those whose stress markers declined showed fewer problems.
• Scientists just found the “master switch” for plant growth September 16, 2025
  Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they created a gene expression atlas that identifies rare stem cell regulators, links them to crop size and productivity, and offers a new roadmap for breeding resilient, […]
• A volcano erased an island’s plants. Their DNA revealed how life starts over September 16, 2025
  Volcanic eruptions on the remote island of Nishinoshima repeatedly wipe the land clean, giving scientists a rare chance to study life’s earliest stages. Researchers traced the genetic origins of an extinct purslane population to nearby Chichijima but found striking quirks—evidence of a founder’s effect and genetic drift. These discoveries shed light on how plants recolonize […]
