  • Even after scientific papers are retracted, hundreds of studies cite them as evidence.
  • Roughly four retractions occur per 10,000 publications, mostly in medicine, life sciences, and chemistry journals.
  • Journals should implement control measures that block the publication of papers that cite retracted papers.

  • Many experts believe that the Moon was formed when a protoplanet named Theia crashed into the Earth 4.5 billion years ago.
  • One flaw in the theory has been that there's no remaining sign of Theia.
  • New research suggests that Theia's mantle was subsumed by Earth and that large anomalous blogs of rock deep within the Earth are its remains.

    Study reveals a "boring" era when Earth was flat, with no mountains

    A study of europium crystals shows the planet was mostly flat during its middle ages.

  • Research teams studied europium crystals to show that Earth was mostly flat in its middle ages.
  • The planet had no mountains and little evolution of life.
  • This period of time is known as the "Boring Billion".
