In our science news update for this week we take a look at hydrogen bonds, water on Mars, and the Ice Age movies. Plus a new section on updating the textbook and a feature video. Enjoy!

The Elusive Hydrogen Bond
China’s National Center for Nanoscience & Technology
From the properties of water to the force that holds together DNA, hydrogen bonds play a central role in the discussion of life. Now, for the first time these weak, yet important bonds have been photographed using a process called atomic force microscopy.

Curiosity Detects Water on Mars
NASA’s Curiosity rover has detected water in the Martian soil. While recent findings have ruled out the presence of methane (and thus probably living organisms), the discovery of water at the Gale Crater once again opens up the possibility that life may of arisen on Mars in the past.

Ice Age: The Effects of Scrat in the Real World
If you have watched any of the ice age movies, you have seen Scrat bury acorns and seeds just before the onset of the glaciers.
Scientists have now brought back to life a 32,000 year old seed buried before the last ice age by a squirrel in Siberia

Updating the Textbooks
As science educators, one of the things we want to do at Ricochet Science is to use this site to continuously update the textbooks that we author. Science is moving at a speed that makes it difficult to keep up with regards to print texts. Therefore, in these updates we have added a new section that brings some of the latest developments in the sciences to the biology textbook.
Flowering Plants May be Older than We Think
A core sample containing fossilized pollen grades has pushed back the earliest dates of flowering plants by almost 100 million years These findings may set the beginnings for the evolution of the flowering plants back into the early Triassic

Video of the Week
asapScience always has some great videos. Our favorite this week is “What if You Stopped Sleeping”. A great introduction to a physiology lecture, especially for college freshman who are cramming before an exam.
