According to philosopher Danni Dennet, the third level of consciousness includes animals that can imagine different scenarios and choose among those scenarios. Take the Western scrub jay, which stores food in many different places. It remembers to eat the tasty worms it hid first, because it knows they expire before the long-lasting peanuts it also hid. It also knows to change hiding spots if other jays see it storing its supplies, as it doesn’t want them stealing them. Read full article here.
‘Ghostly’ neutrinos provide new path to study protons
In groundbreaking research, an international collaboration of scientists from the University of Rochester have used a beam of neutrinos to measure the size and shape of the protons that make up the nuclei of atoms. This feat, once thought impossible, provides scientists with a new way of looking at the small components of an atom’s nucleus and opens up a wealth of new information about the structure of an atom’s nucleus and the dynamics of the forces that affect neutrino interactions. The researchers solved the challenge of harnessing neutrinos in large numbers by using a neutrino detector containing a target of both hydrogen and carbon atoms, and over nine years of data collection at Fermilab’s accelerator.
