Have you ever experienced mind-numbing cold? Or have you ever felt like it was so hot you could barely think? Believe it or not, these expressions are more than just idioms. Research shows that shifts in core body temperature caused by extreme heat or cold can have significant effects not only on mood but also on cognition.

This video is an experiment of gratitude. It experimented the effects expressing gratitude with words, has on happiness.

13 year old Trisha Prabhu of Naperville, IL, is a finalist in Google Science Fair 2014. Prabhu's project focuses on preventing cyber-bullying. Excerpted from her project summary statement: "Cyberbullying may result in depression, low self-esteem and in rare cases suicides in adolescent victims(12-18). Research shows that, over 50% of adolescents and teens have been bullied online and 10 to 20% experience it regularly. Research also shows that adolescents that post mean/hurtful messages may not understand the potential consequences of their actions because the pre-frontal cortex, the area of brain that controls reasoning and decision-making isn't developed until age 25. I hypothesized that if adolescents(ages 12-18) were provided an alert mechanism that suggested them to re-think their decision if they expressed willingness to post a mean/hurtful message on social media, the number of mean/hurtful messages adolescents will be willing to post would be lesser than adolescents that are not provided with such an alert mechanism. In order to check if my hypothesis was true, I created two Software systems: 1) Baseline 2) Rethink. "Rethink" system measured number of mean/hurtful messages adolescents were willing to post after being alerted to rethink, while the "Baseline" system measured the same without the alert. Results proved that adolescents were 93.43% less willing to post mean/hurtful messages using a "Rethink" system compared with "Baseline" system without alert."

Dropping the F-bomb or other expletives may not only be an expression of agony, but also a means to alleviate it Bad language could be good for you, a new study shows. For the first time, psychologists have found that swearing may serve an important function in relieving pain.

Study that show Twitter can cause a risk of heart disease through negative emotions and expressed through Twitter such as anger, stress, and fatigue. Scientists have been using twitter to demonstrate the connection between language and emotional states and their physical outcomes.

Diana monkeys are some of the most clever monkeys when it comes to language. We all know the expression monkey see, monkey do. But should the saying really go monkey hear, monkey do? Recent studies are finding that the language abilities of some monkeys are more sophisticated than previously believed.

Talking is arguably one of the most powerful forms of expression, alongside writing and art. We use our voices to ask questions, to deliver bad news, to tell someone we love them. But the way we talk to each other is changing. The uniqueness of our voices is being drowned out by the pitter-patter of keyboards; we're always typing, texting, responding. The positives: devices like cellphones complement face-to-face or ear-to-ear conversations. The negatives: expecting immediate responses; heightened miscommunication, and muted social interaction.

Amusia is a deficit in musical memory, recognition, and in pitch processing that people can be born with or acquire through brain damage. Some people may think of themselves as being "tone-deaf", but most of these "bad" singers are just that. People with amusia are so unable to hear tones that they even struggle to differentiate between questions and statements when spoken. Language, like music, uses sound to convey meaning; be it a story, or simply an emotion. In fact, music and spoken language use many of the same structural elements: pitch, duration, intensity and melodic contour, to name a few. Melodic contour is the pattern in which pitch changes from high to low over time. This contouring of pitch is often used to express emotion in music. The emotional effect of contouring is appreciated across many cultures and across many age groups. In speech, melodic contour is created by intonation, which allows us to place emphasis upon certain words and distinguish the purpose of the sentence; e.g. whether it is a question, statement or command. These comparisons provide evidence for the overlap of brain areas and mechanisms that underlie speech and music processing. In addition, the storing of sound patterns in short-term memory is also overlapping for both language and music.

Nothing can replace the value of face-to-face communication. In fact, it's said that over 90% of how we communicate is through nonverbal cues like gestures and facial expressions. With that said, one cannot underestimate the power of video conferencing to enable businesses to maximize the effectiveness of their communication.

In various languages there are different ways to express the love for another. However, the article presented goes into the emotional weight that different languages carry. For example, in the Japanese culture, "I love you" is not often said, rather it is implied through actions. Where as in the Western culture, "I love you" is often said and may not necessarily carry as much emotional weight since it is something that is said often.

Throughout the world, languages are going extinct at a rapid rate. Many people have been investigating to see if the internet is to blame for language extinction, or if it is simply a reflection of what is happening in real-world. Some linguists even believe that small languages are given an advantage on the internet because it is a place for languages to be expressed.

Why don't people like the sound of "woman president"? MANY people find the phrase "female president" annoying. But oddly enough, many others find " woman president" to be a problem, too. The problem is not that these expressions are ungrammatical, as Johnson explained in his past column. Yet both have their critics.

Humans can communicate what is going on with them, and dogs can, too. The difference is, while humans primarily use verbal communication, dogs mainly communicate non-verbally through the use of body language and secondarily through vocalizations. This body language includes tail carriage and motion, ear and eye position, body position and movement, and facial expressions.

Americanisms are becoming more common in British English. The author expresses concern over losing more British words. The article also discusses whether Americanisms are necessarily disadvantageous.

Bwahaha! Giving the former colonists a taste of their own medicine by infiltrating the Queen's English.

The author of this piece simply explains how some languages involve more characters than others. Also, this leaves languages like Chinese, Japanese, Korean, etc., with an advantage because they are able to express their thoughts through fewer characters.

This seminal longitudinal study, conducted by Goodwyn, Acredolo and Brown (2000), evaluated the benefits of purposefully encouraging hearing infants to use simple gestures as symbols for objects, requests, and conditions. Researchers measured the receptive and expressive language abilities of 103 babies via standardized language tests at the age of 11, 15, 19, 24, 30, and 36 months. Their findings suggest that symbolic gesturing does not hamper children's early verbal development, and may even facilitate it. The possible reasons underlying the results: increases in infant-directed speech, infant-selected topic selection, and scaffolding that encourages communication.

This article explains why and when we say things such as "please" and "thank you" to others. A recent study has shown that people in informal settings, received expressions of gratitude only a small amount of times in comparison to the amount of requests they complied with or number of times they offered their service or help. Although this may seem like a bad thing, researchers believe this is good news. This article further explains the researchers reasoning.

This is a video link to Tara Fallaux's short documentary "Love Letters," from the Amsterdam-based production company HALAL Films. Fallaux trains the camera on various couples as they read each other heartfelt letters and openly discuss their relationship. We also hear from single people, who read letters they wrote to ex-lovers while reflecting on the trials and tribulations of these life-changing relationships. Love Letters is an intimate rumination on the project of love-and, ultimately, the virtues of vulnerability.
