A baby’s first meals may shape attention for years, with longer exclusive breastfeeding linked to fewer ADHD symptoms through age eight. Researchers at the University of Bergen examined data from 37,600 families in the Norwegian Mother, Father, and Child Cohort Study (MoBa). The association appeared in both boys and girls and was strongest when the […]
Longer Breastfeeding Linked to Fewer ADHD Symptoms in Children

Common Osteoarthritis Treatment Fails a Major Test
Diacerein did not relieve knee osteoarthritis symptoms in a major trial, but patients should speak with their doctor before stopping it. For millions of people living with knee osteoarthritis, medications that can meaningfully ease pain remain frustratingly limited. Now, one drug long valued for its anti-inflammatory properties has failed a major test of its effectiveness. […]
Tiny Stars Are Making the Early Universe Much Harder to Explain
Faint stars hidden inside massive early galaxies suggest some may contain several times more stellar mass than previously estimated. Some of the universe’s earliest massive galaxies may be hiding far more stellar mass than astronomers realized. Their brightest stars dominate what telescopes can see, but new measurements indicate that enormous populations of small, faint stars […]

Dark Stars May Have Left a Gravitational-Wave Signal We Can Detect Today
A new study suggests that pulsar timing arrays could help reveal how the Universe’s first supermassive black holes formed. A faint background of extremely low-frequency gravitational waves, detected by monitoring networks of pulsars, may preserve clues from events that began more than 13 billion years ago. Among them could be the processes that produced some […]
Scientists Reveal How Cells Tame One of Biology’s Most Dangerous Metals
Polyamines may protect cells from toxic iron buildup by keeping reactive iron under control. Iron keeps cells alive, but when too much of it remains chemically reactive, the same metal can become destructive. Excess free iron can drive reactions that damage DNA, proteins, and cell membranes, creating a problem cells must constantly control. Whitehead Institute […]
