In this Tuesday, March 12, 2019 photo, a visitor takes part in an immersive experience showing visitors how dogs see from inside the head of a dog at the California Science Center in Los Angeles. A new exhibit at a Los Angeles museum examines the relationship between dogs and humans and explores why the two species seem to think so much alike and get along so well. “Dogs! A Science Tail” opens Saturday, March 16, 2019, at the California Science Center. (Photo by Richard Vogel/AP Photo)

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.

Light is the sole reason why life exists. It provides us with warmth; it allows us to see; it nourishes all the living things on this planet. Many painters, especially the masters of Old Renaissance Period, have recognized the importance of light and its intimate connection with nature and life itself. In their paintings they gave tribute to light, giving the impression that their paintings had a light source hidden within them. Al Hogue, the artist who created the paintings that you see before you, has studied their techniques for many years. As time went by, light permeated not only his paintings by also his life, becoming his sole philosophy.

Geese fight during the annual Geese Fight Day in the northern Serbian village of Mokrin, some 160km (100 miles) from Belgrade February 22, 2015. Every year in the last week of February, goose fights are held in the northern Serbian village of Mokrin. Left alone, male geese, or ganders, are unlikely to fight each other, hence why females are brought along for whose affections the ganders then fight until one or the other gives up.

This thing has 24 cylinders, 1,704 cubic inches, 12 GMC superchargers (blowers), 8 nitrous bottles and it runs! Why build such a beast? “Because I can,” Harrah says. There’s no other reason to take a 24V71 and build an intake manifold that weighs 1,000 pounds and mount eight 6-71 superchargers on top of four others. This is a V24 Detroit Diesel (normally used to power ships) which is two V12 Detroits joined together nose to nose with splined cranks.

For a long time the laws of Canada have explicitly banned gambling in any form. This may be the reason why the country does not have so many gambling establishments as the USA - but their quality surely makes up for the quantity. The first Canadian casino was opened in Dawson City, Yukon, in 1972 - it was the first one after gambling has been banned in the country in 1892. The Diamond Tooth Gertie's Gambling Casino did not operate for long, though. The first permanent commercial casino was opened in 1989, and it was the first of many - there are currently 75 casinos operating on Canadian soil.

Imagine living in the sea where it is permanently dark, cold, and food is hard to find. For many animals at depth, it may be weeks to months between meals. If you find something to eat, you have to hang on to it. This is why so many deep-sea fishes have lots of big teeth. This dragonfish, spotted off the coast of Australia, even has teeth on its tongue. They would be terrifying animals ... if they weren’t the size of a banana. (Photo by Julian Finn/Museum Victoria)

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.
