As humans, we all need water. The ecosystems of Earth need water too. Unfortunately, many rivers run dry from overuse. If you don’t want to see this happen, one of the things you can do is to save the water that you consume every day. Here are some tips. You can also take the pledge at Change the Course to help restore the Colorado River. Every pledge will return 1,000 gallons to this river.
If you are interested in learning more about freshwater and why it is so important to the world, I would recommend National Geographic’s Freshwater 101 to start your research.
I’m fortunate enough to be part of a friendly walking group. We take evening walks in the winter to look at the stars. We usually take our walks in one of Montreal’s beautiful nature parks, such as Parc-Nature de l’Île-de-la-Visitation, which is located on the north side of the island. We are able to enjoy the night sky, while being surrounded by trees, water, and white snow all around. The scene is spectacular. The next time you are out on a winter night, look up and see if you can recognize Orion, The Hunter.
The BBC has some brief video clips on how to identify some interesting features of the winter night sky. For more details, take a look at Patrick Moore’s book, The sky at night.

ACS (American Chemical Society) Publications has created a series of videos to help authors and reviewers with the process of writing, editing, or reviewing articles. Below is the first episode in the series. It stars Chemistry Professor George M. Whitesides from Harvard University, who has published over 1100 articles and has worked on the advisory boards of multiple peer-reviewed journals.
Hundreds of journals allow authors to submit a video abstract, i.e., a short video describing their research, along with their article. Consequently, results of scientific experiments are now appearing on YouTube and attracting a larger audience. Read this informative article by Jacob Berkowitz to find out more.
While gearing up for the holidays, I found this entertaining video with Engineering Professor Larry Silverberg (a.k.a. Dr. Silverbell), from North Carolina State University, who explains how Santa is able to deliver gifts to children around the world in one night by modifying the space-time continuum and using nanotechnology:
The search commands, AND, OR, NOT, (also known as Boolean operators, named after its British mathematician inventor, George Boole) can be used to combine your words in many search engines and research databases. Here’s a short video that explains how to use AND, OR, NOT when searching:
