  • Zebra finches amazing at unmasking the bird behind the song
    Like humans who can instantly tell which friend or relative is calling by the timbre of the person's voice, zebra finches have a near-human capacity for language mapping.
  • Researchers examine which approaches are most effective at reducing COVID-19 spread
    Researchers have found that physical distancing is universally effective at reducing the spread of COVID-19, while social bubbles and masks are more situation-dependent. The researchers developed a model to test the effectiveness of measures such as physical distancing, masks or social bubbles when used in various settings.
  • Memories create 'fingerprints' that reveal how the brain is organized
    While the broad architecture and organization of the human brain is universal, new research shows how the differences between how people reimagine common scenarios can be observed in brain activity and quantified. These unique neurological signatures could ultimately be used to understand, study, and even improve treatment of disorders such as Alzheimer's disease.
  • A biochemical random number
    Scientists have generated a huge true random number using DNA synthesis. It is the first time that a number of this magnitude has been created by biochemical means.
  • Field geology at Mars' equator points to ancient megaflood
    Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago -- a finding that hints at the possibility that life may have existed there, according to data collected by NASA's Curiosity rover.
