  • The connection of air pollution to lung cancer

    It is widely known that smoking increases your risk of lung cancer. That is not the only risk factor, however. Air pollution plays a role as well. A study by Oregon State University suggests reducing air-polluting PAHs may lower levels of lung cancer deaths. High emissions of polycyclic aromatic hydrocarbons (PAHs) can be linked to…

  • How many near-earth asteroids are there?

    When we hear about another asteroid that will pass by close to Earth, I wonder how many such objects there are, how many we have not identified, and how NASA finds them and calculates their orbits around the sun. More than 10,000 asteroids and comets that can pass near Earth have now been discovered. The…

    Have you ever wondered how you remember how to get to places you have only gone to once? How does the brain generate a map of your route that allows you to retrace your steps another time, perhaps weeks or months in the future? Using virtual reality, neurophysicists determine how environmental stimuli and brain rhythms…

Sometimes these are asteroids that NASA and others have been tracking for some time, but in other cases, they are newly discovered. The consequences of an asteroid hitting our planet range from relatively insignificant to…

  • Supernova Stars Start With a Pre-Event

    Supernova stars are spectacular stars which suddenly get much brighter. This occurs in certain stars that are reaching the end of their lifetime. Before they go all-out supernova, certain large stars undergo a sort of “mini-explosion,” throwing a good-sized chunk of their material off into space. Though several models predict this behavior and evidence from…
