How do vitamins work? - Ginnie Trinh Nguyen

# data[].attributes.attachment_link.description
Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. But if our body doesn’t create vitamins, how do they get into our system? Ginnie Trinh Nguyen describes what vitamins are, how they get into our bodies -- and why…

Memory: It isn't just something, it's everything. And although scientists have pursued and puzzled over it for centuries, a definitive explanation of the actual memory process still eludes us--partly because our brain is so incredibly complex (it is made up of approximately 90 billion cells after all!).

Let's take a look at the basic neuroanatomy elements, which makes memory possible. Brain cells, called neurons are the core component of the nervous system and have the remarkable ability to communicate with each other and transfer information. They are able to accomplish through a process called synaptic transmission. Neurons release specialized proteins called neurotransmitters that travel through the space connecting each other together called synapses, and bind to specific proteins called receptors. In regards to memory, the more often neurons communicate with each other, the stronger the connection between them becomes. This process, called long-term potentiation, is thought to be the foundation of memory storage.

In order for new memory formation to occur, information needs to undergo certain processes. The first is called encoding, a process used to change information into a usable form. Second, memory is stored for later use and finally the retrieval process allows stored memories to be brought back into our awareness.

Memory can go through several different stages before it stored long-term. The first stage is called sensory memory, the shortest element of memory (up to ½ a second). Due to the vast amount of sensory information (sight, hearing, smell, taste and touch) our brain is constantly flooded with, we attend to only certain aspects of this sensory memory, filtering out most of the information. Therefore, only select information is passed into the next stage - short-term memory. This is the information we are currently thinking about and is stored for approximately 10 to 30 seconds.

Want to test your short-term memory? Take a fun memory test here!

While many of our short-term memories are quickly forgotten, making a conscious effort to retain this information allows it to continue on the next stage-- long-term memory. Other helpful techniques include repetition, patterns and imagery, using mnemonic devices and chunking. Information stored in long-term memory is largely outside of our awareness, but can be called back into working memory when needed. It can also be further divided by type including: declarative & procedural; episodic & semantic; and retrospective and prospective.

What parts of the brain are involved in these different types of memories? Find out here.

While memory fascinates our culture, the loss of it causes even greater fascination (and anxiety), in part, because we ALL experience it. For example, how many times have you been late for something because you can't remember where you left your keys? Or how many times has someone's name suddenly eluded you? Because memory loss can be very concerning-it's important to understand the underlying factors causing or contributing to it, especially if it becomes severe. Read more about additional causes of memory loss (besides those mentioned in the lesson), including: Alzheimer's Disease, Stroke and certain types of Medication.

The good news is that no matter what your age, it's never too late to take steps to prevent memory loss. A healthy lifestyle and good habits can reduce can only help to preserve and improve your memory. Find out some additional ways to give your brain a work out (for example, learning a new language) to help keep your memory sharp.

How memories form and how we lose them - Catharine Young

# data[].attributes.attachment_link.description
Think back to a really vivid memory. Got it? Now try to remember what you had for lunch three weeks ago. That second memory probably isn't as strong-but why not? Why do we remember some things, and not others? And why do memories eventually fade? Catharine Young gives the basics on memory and memory loss.

The first ever vaccine was created when Edward Jenner, an English physician and scientist, successfully injected small amounts of a cowpox virus into a young boy to protect him from the related (and deadly) smallpox virus. But how does this seemingly counterintuitive process work? Kelwalin Dhanasarnsombut details the science behind vaccines.

Some people take aspirin or ibuprofen to treat everyday aches and pains, but how exactly do the different classes of pain relievers work? Learn about the basic physiology of how humans experience pain, and the mechanics of the medicines we've invented to block or circumvent that discomfort.

Interested in the theories of pain, dating from the 17 th century until modern times? See this article.

Interested in how individual variability in brain circuits are related to mind-wandering from pain? See the original article and discussions in the scientific community Pain Research Forum and in the Health News from NPR.

Interested in learning more about pain treatment and research? The International Association for the Study of Pain (IASP) mission "brings together scientists, clinicians, health-care providers, and policymakers to stimulate and support the study of pain and to translate that knowledge into improved pain relief worldwide."

The IASP has a task force that develops pain-related terms and their definitions.

We think of pain as a symptom, but there are cases where the nervous system develops feedback loops and pain becomes a terrifying disease in itself. Starting with the story of a girl whose sprained wrist turned into a nightmare, Elliot Krane talks about the complex mystery of chronic pain and reviews the facts we're just learning about how it works and how to treat it.

At any moment, there is an electrical storm coursing through your body. Discover how chemical reactions create an electric current that drives our responses to everything from hot pans to a mother's caress.

Learn more about the influenza pandemic of 1918-19, which claimed the lives of 50 million people worldwide. Investigate how the media chronicled the pandemic, and explore personal accounts of the crisis. Good resources include:
The U.S. Department of Health and Human Services "The Great Pandemic: The United States in 1918-1919," http://1918.pandemicflu.gov/
The National Archives "The Deadly Virus: The Influenza Epidemic of 1918," http://www.archives.gov/exhibits/influenza-epidemic/
PBS's "The American Experience: Influenza 1918," http://www.pbs.org/ americanexperience/films/influenza/player/ (watch the documentary online)
Visit your local library or historical society to research the influenza pandemic in your own community. Then prepare an online exhibit or documentary to share what you've learned.
Epidemics and pandemics are hot stuff in Hollywood. Wipe down some chairs with disposable disinfectant wipes, dole out the latex gloves, and pass around the popcorn for an infectious disease film festival. Your queue might include Contagion (2011), Pandemic (2009), Carriers (2009), I Am Legend (2007), and Outbreak (1995). Do these films impart any useful information about epidemics and pandemics? Do they promote panic? Or do they simply satisfy our craving for a good, short-lived scare?
