Another reason to hate glitter — it damages river ecosystems

The research found that after 36 days, the presence of glitter halved the root length of common duckweed (Lemna minor), while levels of chlorophyll in the water were three times lower than in control conditions, indicating reduced levels of phytoplankton, or microalgae. Glitter is used in a variety of decorative ways, including on clothing, in arts and crafts, and in cosmetics and body more

The making of 'Son of the Storm

I was recently commissioned by Lauren Panepinto of Orbit books to create the cover for the upcoming novel, ‘Son of the Storm’, by Suyi Davies Okungbowa. Some clients come to me with no idea of what they want to see on the cover. They give me a manuscript, and just let me see where it takes me.

Why Planes Don't Fly Over the Pacific Ocean

Why do airlines avoid the Pacific Ocean? You might think it was a safety issue. The Pacific is the largest and deepest of the world’s oceans. If a plane encounters a problem over a seemingly endless and bottomless pond of water, the pilots are going to have a rough time finding a safe spot to set her down.

Guessing that it is a safety precaution wouldn't be entirely wrong. When planning a route, many pilots prefer to maximize the number of airports along their path. Emergencies are incredibly rare relative to how many planes take to the skies every day. That said, it isn’t the main reason airlines tend to avoid making a straight shot east to west.


E/Z Alkenes, Electrophilic Addition, & Carbocations

Alkenes are an important type of molecule in organic chemistry that we’re going to see a lot more of in this series. But before we can really get into the many cool reactions alkenes do, we need to go over some of the basics. In this episode of Crash Course Organic Chemistry, we’ll review and build on our knowledge of alkene nomenclature, revisit our friend the carbocation, and learn Markovnikov’s Rule: an important tool that will help us predict the products of addition reactions involving alkenes.
