Since its discovery in 2010, researchers have been trying to solve the mystery of dark streaks that appear and disappear seasonally on the planet's surface (shown above). Scientists are now claiming that this phenomenon, known as the recurring slope lineae, is caused by a bath of saltwater. What is still unknown, however, is where the water is coming from, or if the chemistry is even right for supporting life.

Did you know that McDonald's famous burger, the Big Mac, contains addictive ingredients inside its bun? Yes, it's true, the bun isn't as harmless as your probably thought.

The Big Mac bun contains high levels of high-fructose corn syrup and sodium. Both ingredients are addictive, and therefore make your body crave more of them. These ingredients are also harmful and can cause obesity, diabetes, and heart disease, BUT not directly. Remember, the higher sweetness of high-fructose corn syrup increases craving and consequently the amount consumed. Obesity isn't caused by diet alone - when combined with decreased physical activity, that is when it contributes to the weight gain epidemic and personal health problems.

It's no wonder homemade burger ...

The images, taken by NASA's New Horizons spacecraft from a distance of 18,000 kilometres give Pluto a "strangely Arctic look", NASA scientists said.

The study, titled "CFT 70 (Countermeasure and Functional Testing in Head-Down Tilt Bed Rest Study)," aimed to learn more about how human bone and muscle might deteriorate in space. According to Drew Iwanicki, who took part in the study and who is pictured above, he experienced some serious headaches because of increased blood pressure to his head. His spine went through some serious pain, and staying horizontal was difficult. However, as soon as the bed was tilted to the vertical position, after 70 days of course, his legs felt heavier and his heart started to beat at 150 BPMs.

Sometimes it pays to have big, bad neighbors! Tiny black-chinned hummingbirds (shown above) have learned to build their homes near hawk nests. The hawks are too big to be interested in teeny hummingbird eggs, and they scare off the medium-sized birds that are.

According to the study, of the 342 hummer nests studied over three years, 80% were near hawk nests - and for good reason. The researchers monitored hummingbird egg and fledgling survival near six active and six inactive hawk nests. Those hummers unlucky enough to be near inactive nests lost all but 8% of their young, while those in a “good” neighborhood had a 70% success rate, they report.

Known an fibrodysplasia ossificans progressive, or FOB for short, this disease can suddenly turn a person’s tissues and muscles into bone, thereby permanently immobilizing parts of the bodies. Joints such as elbows or ankles may become frozen in place; jaw motion can be impeded and the rib cage fixed, making eating or even breathing difficult. Currently, no cure exists to combat this rare condition.
