A man speaks on his mobile phone on May 31, 2011 in New York City. In a new report by 31 scientists meeting at the World Health Organization's International Agency for Research on Cancer (WHO/IARC) it was found that using a mobile phone may increase your risk for certain kinds of brain cancers. While further scientific work will be conducted, the group of scientists from 14 countries classified cell phones in the carcinogenic category 2B, which is similar to the pesticide DDT and gasoline engine exhaust.

Why would you want to buy a Christmas tree if you have a luscious full beard? Or maybe you have a friend that is willing to volunteer? Just glue some ornaments onto his facial forest and make him stand in the corner. Just don’t forget to feed him! You don’t want your Christmas tree to go bad before the holidays are over! Stephanie Jarstad had created something similar in her project, The Twelve Bears of Christmas, in order to honor the Decembeard (much like Movember), in order to bring awareness to Men’s health problems.

This graceful husky appears to be smarter than your average dog having apparently mastered the art of walking on water. The soft-footed canine was photographed while making its way across a lake in northern Russia. Photographer Fox Grom captured a remarkable set of images after heavy rain fell on a frozen lake to create the amazing illusion. The 40-year-old, who works as an all-terrain vehicle driver, regularly walks his pet dogs, Alaska and Blizzard, near the natural beauty spot. “I always take pictures of my dogs whilst walking them but on this occasion there was an extraordinary phenomenon“, he said. “The ice was already very thick when it rained heavily making for a spectacular scene”. Here: Husky dog Alaska walks on water in Northern Russia, January 2015. (Photo by Fox Grom/Visual Press Agency)

Everyone wants to get something for nothing - whether it's a lucky upgrade that means you can turn left when you get on a plane instead or heading off into the economy seats, or even getting a few extra features thrown in for free when you buy a new car.

As some of the sharpest businesses around, no-one understands this quite as well as casinos and that's why they all have a system that they call comps. It's short for "complimentary offers" and these are special treats specially designed to reward you for your loyalty to the casino in question. They're basically bonuses.

The Bund Sightseeing Tunnel is not an adventure for the light hearted. The trippy visuals and sound effects are rather bizarre and creepy. They look like something out of a nightmare or a psychedelic trip. Maybe the creators of this project did experiment with some illicit drugs to gain inspiration for this project. Moreover, it is more likely than not that some people tried going to this tourist attraction after “preparing” themselves beforehand. This trippy tunnel stretches from Pudong to Puxi in Shanghai, China, and is rated as one of the top five tourist attractions. We recommend visiting this place; just don’t take your kids along for the ride, since it might prove to be too scary for them.
