There's very little scientific evidence to suggest our perception of time changes as we age. And yet, we consistently report that the past felt longer — that time is flying by faster as we age. What's going on? By Brian Resnick.

Neuroscientists have struggled to understand exactly how the mind’s cycles affect us. Studies of donated brains provide some answers. By Carl Zimmer.

From astronomy to religion, the year's shortest day brings enduring mysteries. By Brian Handwerk.

This incredibly simple time management system changed my workday. By Chris Winfield.

Entropy caused by quantum fluctuations measured at the molecular level. By Jon Cartwright.

On viewing my wrinkles through Proust, Rembrandt, and plastic surgery textbooks. By Alyssa Pelish.

Brain cells that track our location also can track time and distance, a study finds. This could explain how the brain uses place and time to organize memories throughout our lives.

Daylight saving time ends Nov. 3, setting off an annual ritual where Americans (who don’t live in Arizona or Hawaii) and residents of 78 other countries including Canada (but not Saskatchewan), most of Europe, Australia and New Zealand turn their clocks back one hour. It’s a controversial practice that became popular in the 1970s with the intent of conserving energy. The fall time change feels particularly hard because we lose another hour of evening daylight...

The clocks fall back by an hour this weekend as America returns to Standard Time. This signals lighter mornings and an extra hour in bed. But what time do we reset our watches?

Fredric Jameson reviews “Time Travel: The Popular Philosophy of Narrative” by David Wittenberg.

I’m not a vacation kind of guy. Oh, sure I’m a consummate relaxer, but a comfy couch, good book, and some video games with my seven year old son beats a long plane flight, rental car, hotel room, and tourist traps on any day. Don’t get me wrong, I tend to enjoy travelling once I’ve arrived...

Humans are good at a lot of things, but putting time in perspective is not one of them. It’s not our fault - the spans of time in human history, and even more so in natural history, are so vast compared to the span of our life and recent history that it’s almost impossible to get a handle on it. If the Earth formed at midnight and the present moment is the next midnight, 24 hours later, modern humans have been around since 11:59:59pm—1 second.

When humanity plans on a geologic time scale. By Elmo Keep.

Humans think about the underlying systems we use for keeping time in much the same way that fish think about water. We simply don’t.

If you are following the battle of the short messaging systems, you might think it is a one-dimensional contest between the systems that maintain your chat history for all time – like Twitter and Facebook – and the so-called disappearing messengers – like Snapchat – where messages vanish after being read.

In homage to the 60th anniversary of the world’s first atomic clock, it’s time to ask what time actually is and whether it even exists.

I spent my 20s in the service industry, overworked and underpaid. Why, now, do these games help me relax? By Laura Hudson. (April)

Lab experiments suggest that a strange synchronization of pendulum clocks observed in the 1600s can be chalked up to acoustic energy. By Jesse Emspak.

Classical physics, with its totally determinative, forward-in-time, billiard-ball causation, requires sweeping anomalies like psi under the rug, not to mention resigning ourselves to an absence of higher meaning and direction in the universe. Even the local islands of order allowed within the framework of dynamical systems theory... By Eric Wargo.

Here we go again. The movie Predestination, released in the UK this week, is the very latest in the long history of time travel films. There's been more than 100 since the Terminator and Back...
