We here at SciShow know of two things that can help you get through this flu season: a flu shot, and watching this video. Make sure you do both!

Most of the cases we call “electrocutions” are actually electric shocks: an electric current running through a body. Whether an electric shock becomes an electrocution depends on the nature of the current involved.

Our interpersonal relationships start forming as soon as we’re born, and psychologists have studied how those early connections can set the stage for the other relationships we form later in life.

Many of us have longed for cool sci-fi inventions like a holodeck or replicators, but there's one tool we're actually getting pretty darn close to creating: the medical tricorder.

Last week, a group of researchers unveiled a vaccine that cures cancer in mice, and if we can get it to work in humans, it will save a lot of lives.
