This video explains it quite well. The key hormone in question is serotonin. Serotonin is known to play a role in depression. Low serotonin levels are believed to be the reason for depression and associated symptoms of anxiety, apathy, fear, feelings of worthlessness, insomnia and fatigue. The opposite is true when a high-level of serotonin is present, you feel jovial and enthusiastic. MDMA promotes the formation of this hormone.

You guessed it! The tufted ground squirrel (Rheithrosciurus macrotis), also known as the vampire squirrel.

Check out what may be the first video of the remarkable and rare animal. This species of squirrel is twice the size of most tree squirrels, reputedly has a taste for blood, and has the bushiest tail of any mammal compared with its body size with its tail being 30 percent larger than its body.

Just wait until they put these in phones so that they can self-destruct once a user's contract is through!

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.

I was shopping around in Michigan a few weeks ago when I stumbled upon this product proudly made by the Velvet Peanut Butter Company. I was appalled when I read that it's made from Fully Hydrogenated Vegetable Oil, while the trans-fat count is at zero grams - a very misleading claim.

This product is literally poisonous for human consumption, yet it is prepared for young children and people of lower socioeconomic status, given its low price tag. Hydrogenated oil is scientifically known to increase LDL 'bad' cholesterol and lower HDL 'good' cholesterol, thereby leading to heart disease and cancer. It should be against the law to feed it to kids.

In the United States, labelling a product trans-fat free doesn't necessarily mean it doesn't conta ...

A new international study estimates that there are more than 3 trillion trees on Earth, about seven and a half times more than some previous estimates. This number was formulated by collecting tree density information from more than 400,000 forest plots around the world. But the total number of trees has plummeted by roughly 46 percent since the start of human civilization. The results provide the most comprehensive assessment of tree populations ever produced and offer new insights into a class of organism that helps shape most terrestrial biomes.

Southern rockhopper penguins (Eudyptes chrysocome) mate for life, reuniting with the same partner year after year during mating season. But even though they're monogamous, a new study reveals that penguin couples really don’t spend much time together.

Using GPS trackers mounted to the penguins’ legs, scientists monitored 16 birds over the course of a mating season. The data show that males arrived at the nesting site approximately 6 days before their female counterparts and stayed about 6 days longer. However, the short mating season means the pairs are only united for about 20 to 30 days a year. And when they were separated, it was usually by a large distance: During the winter months, partners were separated by an average distance of abo ...
