Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons.

It is naturally very short-lived, but researchers including those from the University of Tokyo successfully cooled and slowed down samples of positronium using carefully tuned lasers.

Teton County Sheriff's Deputy Ashley Hayes detained a woman and her boyfriend because they "were at a gas station an abnormal amount of time." They were ultimately held for over 90 minutes, while a drug dog was brought to the scene, unsuccessfully searching them for drugs. The boyfriend was arrested for refusing to sit on a curb during the detention, despite the fact that no crime had even been alleged to have occurred. The video went viral locally, with many residents calling for the termination of the deputy. The sheriff acknowledged the existence of the video, but has refused to comment on the situation due to the pending (bogus) charges against the boyfriend. So basically, a couple went to the gas station, and then got harassed by some cops for no actual justified reason.
