Turns out that fish oil only benefits those who have the right genes
|
view preview
Most foods today are fortified with essential oils like omega-3 fatty acids. Naturally, these oils are found in fish, and are known to benefit many parts of the body, including the eyes, brain, heart, and joints. So, are these so-called beneficial oils important for people who lack the DNA profile needed to metabolise them? It turns out that the extra omega-3 might not do much good at all. According to a study published in Science, Inuit people living in Greenland whose traditional diet of fish and marine mammals have the right enzymes in their bodies needed to metabolise these foods that are very high fat content. The researchers reported that their DNA that was most different was on chromosome 11, specifically among genes that control the ...

Speedy bacteria
|
view preview
Bdellovibrio bacteriovorus is a bacterium that attacks other bacteria. It can charge its prey at speeds of up to 100 micrometers per second, comparable to a human running 600 kilometers per hour. It then bores into its hapless victim by spinning at 100 revolutions per second. Most bacteria aren't quite that fast, but they can move by whipping flagella or by spiraling through their environment. ...

Craving a Big Mac? I don't blame you
|
view preview
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 ...

Tiniest snails you'll ever see!
|
view preview
Angustopila dominikae is the only known specimen measuring the astounding 0.86 mm in shell height. That means ten of them could fit into the eye of a large sewing needle at the same time! Until now, the smallest known land snail was a thai species measuring about 0.9 millimeters long. Researchers believe that it probably feeds on microorganisms and may be hermaphroditic. However, because the team didn’t recover any DNA, a lot of uncertainly remains. ...

Definitive proof of water found on Mars
|
view preview
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.
