According to a new study in the Proceedings of the National Academy of Science (PNAS), a dopamine circuit in the brain sends out the signals that initiate fear extinction in mice, enabling these animals to overcome their trepidations.“Dopamine is essential to initiate fear extinction,” said Michel ...read more
We’re constantly making memories with every experience, but how do they stick with us? It turns out that a good night’s sleep makes them last. Recent research shows that as we sleep, the neurons in our brains undergo processes that not only preserve past memories but also prepare for the creation of new memories to come. A new study published in Nature Communications captured memory processing in mice by following neuronal activity in their brains before, during, and after learning experienc ...read more
Does seismic activity under this long-dead volcano mean it’s about to rise from the grave? That’s what an international research team set out to discover as this Bolivian “zombie” volcano continues to show signs of activity.Using modern technology, the team mapped out the internal workings of the volcano and determined how likely it could erupt, according to a new study, published in the Proceedings of the National Academy of Sciences.Uturuncu, The Zombie VolcanoUturuncu hasn’t erupted ...read more
Remains of an ancient noblewoman have been discovered at a site unfit for a queen — a former garbage dump in Caral, Peru. The dump became an archaeological site in the 1990s.Archaeologists in what may be one of the oldest cities in the Americas, unearthed the mummified woman who was between 20 years and 35 years old. They estimate she was buried about 5,000 years ago. Her body was wrapped in cotton fabrics, reed mats, and covered by a panel embroidered with macaw feathers. She also wore a hea ...read more
