From climate change to star-navigating beetles, there were some interesting science articles released during the week of January 21-25. Here are a few that we think are relevant for the science classroom:
Quadruple helix DNA discovered in human cells (New Scientist, January 23, 2013)
We have all heard of the double-helix, but a quadruple helix? Researchers have not only discovered evidence of a quadruple helix in cells, but also discuss how this may be used in the treatment of cancer. Great article if you want to talk about the possibilities of DNA structure.
How High Could the Tide Go? (NY Times, January 21, 2013)
With the aftermath of Hurricane Sandy, and with more climate change related disasters in the imminent future, scientist have begun a vigorous task to look back towards past climate change events, and the sea level rises that have occurred alongside such warming, to predict future damage to the world’s coastlines. The article also provides an interesting way to show how the fossil record is used for more than evolutionary studies.

Dung beetles steer by the Milky Way (ScienceNews: January 24, 2014)
People have used the stars to navigate at night for thousands of years, while more recent studies have shows that other animals such as seals and some birds use the same methods of celestial navigation. Now, the dung beetle has been added to the list of star-tracking navigators.
