  • Growth in the earliest trees
    Researchers report remarkably well-preserved fossil tree trunks from Xinjiang, northwest China, approximately 374 million years old, suggesting that Earth’s earliest forest trees were able to achieve great size by a unique strategy that involved building a hollow cylindrical skeleton of interconnected, growing, woody strands that tore itself apart and collapsed under its own weight in a controlled manner as the tree’s diameter expanded.

  • Face and color processing in humans
    In a neurosurgical patient with intractable epilepsy who was temporarily implanted with electrodes, electrical stimulation of face-selective and color-associated brain regions while the patient viewed various objects led the patient to report seeing illusory faces and rainbows, respectively, suggesting that the corresponding brain regions may be specific to face and color processing.
