The ethics of brain science: Open your mind

May 26, 2002

Advances in neurotechnology raise ethical and legal questions.

  • Neuroscientists will soon be able to screen people’s brains to assess their mental health; functional MRI can identify depressed individuals and other personality traits and detect lies. That information could be available to employers or insurers.

    The Extraordinary Tale of Red Rain, Comets and Extraterrestrials

    September 1, 2010

    Optical microscope images of red cells: (A) red cells before autoclaving (400x): cells evenly dispersed in the rain water. (B) red cells after 1 hour incubation at 121oC (1000x).(C) after 2 hour incubation at 121oC (1000x).

    For years, claims have circulated that red rain that fell in India in 2001 contained cells unlike any found on Earth. Now new evidence that these cells can reproduce is about to set the debate alive.
