Well I don't know if its my favourite element, (I've always been partial to niobium), but this video is a nice introduction to the amazing versatility of Silicon.

Awesome site for visualizing atoms
Here's a fun webpage for visualizing the electron filling in atoms. They also use a nice adaption of the Bohr model that incorporates the s, p, d, f shells from the quantum model.

New fossil has interesting implications
Science is always in flux and the theory of evolution is no exception. Recently David Lordkipanidze et al. discovered a fossil of a skull which appears to have belonged to Homo Erectus in Dmanisi, a small town in southern Georgia. This significant discovery seems to suggest that some of the Homo species previously identified in the same region are more likely variations of Homo Erectus. As the authors make clear, its not that the previous science was bad or wrong, but that the science needs to adapt in light of new results.
The Guardian has some nice coverage of this work, including this introductory video below and the article here. If you have access to Science you can read the article for yourself here.

18ft fish found off the coast in California
An 18ft Oarfish was found off the California coast. This monstrous fish weighed enough that it took 15 people to drag it onshore. It was found by Jasmine Santana of the Catalina Island Marine Institute and represents a unique find. The oarfish is capable of dives of at least 914 meters, making its observation rare.

Awesome video on the quantum mechanical model of the atom
This TED-Ed talk by George Zaidan and Charles Morton (animated by Karrot Animation) on the model of the atom is fantastic. It presents a clear, accurate and accessible description of the quantum model, which can be a conceptually challenging subject.

Microscopes don't need to be expensive.
Science is everywhere and accessibility shouldn't be a matter of money.
Check out this instructable by user Yoshinok on how to make a $10 stand that converts your smartphone into a microscope. They achieved up to 175x magnification! That's enough to visualize large cellular structures.
