Thank you in advance for your patience as I continue to change the format of this blog post! Starting now I'm going to compile a list of the week's best articles (in my humble opinion, of course.) I may not be able to summarize them all, but don't want you to miss anything!
Below are all the articles covered on Episode 19 of my podcast, Spaced Out.
Dark Matter is Everywhere…Or Is It?
According to astronomers, distant galaxies have surprisingly low levels of dark matter, the stuff that scientists believe make up the bulk of all matter in the universe. “Stars in the outer regions of some far-off galaxies move more slowly than stars closer to the center, indicating a lack of dark matter, astronomer Reinhard Genzel and colleagues report online March 15 in Nature.” If this information is confirmed (not sure how researchers could possibly do that but whatever), it will change the way astronomers view dark matter’s role in the creation of the early universe.

Did Your Device Just Explode?
Galaxy Note 7s and hoverboards are exploding all over the place, literally. Why? Mal-functioning Li-ion batteries. Commercialized by Sony in 1991, Li-ion’s are used in pretty much EVERY device (even the Mars Curiosity rover uses one). Lithium is the lightest metal around, highly reactive, and generally pretty safe…so why have they become so dangerous? The batteries consist of Lithium Cobalt Oxide (LiCoO2), Graphite, Polypropylene, Ethylene Carbonate, and Lithium Hexafluorophosphates (LiPF6), but only LiCoO2, Ethylene Carbonate, and LiPF6 are hazardous. If LiCo2 becomes hot it can crumble and create a combustible environment. Ethylene Carbonate is a flammable liquid that if exposed to oxygen, will explode. LiPF6 isn’t combustible or flammable, but it burns skin on contact.
