If you've ever battled crowds to get a coveted toy you know that early October is the perfect time for parents to start holiday shopping. Amazon knows this, which is why the company is holding a second Prime Day sale event--which ends tonight--featuring some great Prime Day toy deals. You can find all the best Prime Day deals here. But if your kids are like my kids, they're already working on their wish lists. If you say you haven't already started budgeting, you are either lying, financially irresponsible, or your children are much less demanding than mine are (I know, it's my fault).

We used to think that planning for the future was a skill most children have by the age of four, but now it seems that we don't develop the kind of memory needed to do this until we're older. Episodic memory lets us reflect on our past, and imagine ourselves in the future. To find out when children develop this, Amanda Seed at the University of St Andrews in the UK and her colleagues devised a test for 212 children between the ages of three and seven. Each child was taught how to use a box that released a desirable sticker when the correct token was placed in it. An examiner showed them two boxes of different colours and told them that one would remain on a table while they left the room, and the other would be put away.

Netflix is still surprised that Stranger Things, a science-fiction series starring five young kids, became a worldwide sensation immediately after it was released. Unlike some of its biggest hits, like House of Cards (which is based on a British series), Stranger Things was an unknown property when it premiered in July of 2016. But it quickly captivated audiences, thanks to its '80s nostalgia and the perfectly executed homages to Hollywood classics from the likes of Stephen King and Steven Spielberg. As the series created by the Duffer Brothers enters its second season on October 27th, we talked to Director of Photography Tim Ives about what it's like to shoot it. Ives, who has previously worked on shows like Girls, Mr. Robot and House of Cards, said one of the most important elements was to keep Stranger Things 2 feeling retro.
