From the cities we live in to the technologies we use every day, here are some amazing before-and-after photos that show just how quickly the world changes.
In an age of emails and texts, it’s rare that we sit and reflect on our relationships the way couples used to do in love letters. Indeed, it’s one tradition that needs to make a comeback.

A lot of people have some pretty big misconceptions about space and Earth. To be fair, very few of us have ever been, there’s a lot more to study before anybody really knows what’s actually going on up there, and movies tend to give us the complete wrong idea.

We’ve all experienced the effects of color, whether we’ve realized it or not. And it is no coincidence that most restaurant logos use the same two colors or that hospitals are usually staffed by nurses wearing baby blue scrubs.

However, most psychologists believe that our brain interprets color for a reason and that, therefore, each color must affect us in a different way. Here are ten colors and how each one affects your brain.
Emerging technologies will almost certainly revolutionize the future of forensic science, making the capture and conviction of criminals increasingly likely. These technologies can help investigators in missing persons cases, cold cases, sexual assault cases, and murder cases. Although potential dangers related to personal privacy have caused controversy about the use of these innovations, it seems clear that these ten cutting-edge innovations in the future of forensic science also promise enormous benefits to authorities, victims, victims’ families, and society in general.
Although Chinese medicine, holistic therapies, and ritualistic shamanism are often viewed as pseudoscience, they are actually ancient practices that have been around for thousands of years. And due to raised interest worldwide, scientists are now running countless research trials to try and discover if there is any truth in these several common ancient practices. In fact, in recent years, advancements in technology (such as brain imaging) has allowed modern science to validate a number of teachings and beliefs rooted in ancient wisdom that, up until now, had been trusted but unproven empirically. Here are 10 ancient practices that have been confirmed by modern science research.
When you’re trying to teach dozens of students the finer points of history and science, sometimes it’s just easier to provide a simpler narrative. But as James Loewen chronicles in his classic book “Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong,” teaching simplistic narratives of history doesn’t do anyone any good. Besides history, the same issue exists in other subjects as well. No, Isaac Newton didn’t “discover” gravity when an apple fell on his head. And yes, Pluto is still a planet — it’s just a special kind of planet. Like many myths, these stories often have a kernel of truth to them — it just isn’t what you learned. Here are 14 things you may have learned in school that have since been proven wrong.
Over the centuries there have been many natural disasters that have stolen human lives and left destruction and havoc for the survivors. Sometimes these incidents are ranked based on damage, loss of lives or the amount of money that it cost to rebuild.
