World's largest vacuum
|
view preview
See what happens when scientists drop a bowling ball and a feather in the world's largest vacuum; for the science-illiterate viewers out there (sorry ), a vacuum is a space entirely devoid of matter (also known as an absolute vacuum). A lot of you probably already know how this one ends, but that doesn't make watching it play out any less spectacular. ...

Why do we listen to sad music?
|
view preview
No one wants to be sad. So why do we love listening to sad songs so much? New research suggests that we're drawn to sad songs because they evoke mostly positive emotions, which is great for our mental health. According to the study published by the journal PLOS One, researchers found that "a wide range of complex and partially positive emotions, such as nostalgia, peacefulness, tenderness, transcendence, and wonder," were brought out in the participants that took part in the study by sad music. These are emotions are all healthy, feel-good emotions. The researchers concluded that "Music-evoked sadness plays a role in well-being, by providing consolation as well as regulating negative moods and emotions."

When's the best time to make a decision?
|
view preview
You might think that it's better to be well-fed rather than starving when you're trying to make a big, life-changing decision, but new research suggests quite the opposite. According to a research study conducted by Utrecht University in the Netherlands, people who were hungry because of having fasted overnight perform better on a complex decision task than sated people. ( Click here to read the research). This provides a first piece of evidence that the hot state of hunger improves, rather than compromises, advantageous decision making. Their experimental evidence suggests that the "hot state of hunger promoted rather than compromised complex decisions with uncertain outcomes that are advantageous in the long run as hungry participants were ...

What a flame looks like in microgravity
|
view preview
Flames look a little different in space. On Earth, gravity causes a candle flame to be teardrop-shaped, and carries soot to the flame's tip, making it yellow. In microgravity, where these forces are absent, the flame is spherical, soot-free, and blue.

Trippy mushrooms
|
view preview
Users of magic mushrooms often report altered states of consciousness and a synesthesia-like melding of the senses. Now, scientists may have figured out why: Psilocybin changes the brain’s wiring, creating a hyperconnected brain that contains links between regions that don’t normally communicate with each other. Communication between brain networks in people given psilocybin (right) or a non-psychedelic compound (left). ...

This predatory worm found in Peru glows in the dark
|
view preview
This glowing worm is the larvae of a species of click beetles, which belong to the family Eliteredae. Click beetles typically make a clicking motion to quickly escape predators. Of the 10,000 beetles identified, only 200 are bioluminescent. It is hypothesized that the beetle larvae glow green to lure prey such as ants and stick insets. When presented with these insects, the worms readily devoured them. While most beetles dine on flowers and other plant-matter, their larvae are mostly predatory. The insects wait with jaws open, and as soon as an ant or a termite flies in, their jaws clamp shut. Source: http://www.livescience.com/48790-photos-peruvian-glow-worm.html ...
