  1. Paleontology

    Irish elk survived after ice age ended

    New fossil finds indicate that the so-called Irish elk, previously thought to have died out at the end of the last ice age, survived in some spots for several millennia more.

  2. Health & Medicine

    Malaria vaccine shows promise in Mozambique

    An experimental malaria vaccine tested on children in Mozambique provides some protection against the potentially life-threatening disease.

  3. Brain-based help for adults with dyslexia

    Intensive phonics instruction for adults with dyslexia yields brain changes that underlie their improved reading ability.

  4. Summer births linked to schizophrenia

    People who develop a severe form of schizophrenia are strikingly likely to have been born in June or July, raising the possibility that seasonal influences on early brain development contribute to this disorder.

  5. Health & Medicine

    Sleep apnea may be a risk factor for attention-deficit hyperactivity disorder.

  8. Health & Medicine

    High-fat diets slim down learning

    High-fat diets decrease the ability of male rats to learn and remember.

  9. Planetary Science

    Titanic Close-up: Cassini eyes Saturn’s big moon

    Using radar to penetrate the thick haze surrounding Saturn's moon Titan, the Cassini spacecraft has found evidence that the moon's surface is coated with hydrocarbons and dark patches that might be lakes of ethane or methane.
