There's nothing more jarring than the sound of your morning alarm. Even hearing it on others' phones, hours after your own abrupt wakeup, can cause you to flinch in fear. Though we depend on that shrill sound to get up each morning, it's actually better to wake up naturally—so don't even think about hitting that snooze button.
Happiness is a rather fuzzy concept and can mean many different things to many people, but one thing remains constant - the science behind happiness is always the same. [Infographic]

One in five U.S. adults shows signs of chronic sleep deprivation, and a shortage of sleep has been linked to health problems as different as diabetes and Alzheimerâs disease. Recent studies have found some interesting connections between illness and what is happening in our brains as we snooze.

Sleep, or a lack of it, is proven to be linked to clinical depression. Here's how many hours of sleep you need to avoid depression.
Definition Nerve cells arranged in networks communicate information with one another through neurotransmission which is the conduction of electrical messages from neuron to neuron. The electrochemical messages cross the synapses between neural cells by way of special chemical messengers called neurotransmitters. Neurotransmitters are chemicals found and produced in the brain to allow the transmission of impulses from one nerve cell to the next across synapses. They aid in the conduction of information throughout the body. These chemicals fit into specific receptor cells embedded in the membrane of the dendrite that either fuel up or excite action in the cells (excitatory)

Dear Friends - This is a project near and dear to my heart! Every year there's a wonderful prom for teenagers and young adults with kidney disease. Everything at the 2010 Renal Teen Prom is FREE - gowns for the girls and ties for the boys are donated, dinner and party treats included, transportation is covered. Long time survivor, Lori Hartwell, founder and president of RSN, glowed with happiness watching the teens dance, laugh, and make friends at last year's event. “That’s why I created the Renal Teen Prom,” she exclaimed. “I missed my own prom because of chronic kidney disease, which I have had since I was 2. I spent all my teenage years on dialysis. I know that one friend can make a difference, and we give these young people the chance to get to know others who are like them, walking in the same shoes.” This is the 11th annual prom and I am so honored to help with planning it this year. Lori Hartwell and her team do a fabulous job! The theme is "Masquerade!" Please send this info on to young kidney patients, friends and family. And if you'd like to donate, or live in the LA area and can drive a teen, please follow the link below. rsnhope.org/programs/renal_teen_prom2.php Jenna and her brother will also be volunteering again this year! Please contact me if you'd like more information.

Hypocretin (Hcrt, also called orexin) neurons have been implicated in the pathology underlying narcolepsy. The number of Hcrt cells in normal humans ranges from 51,000–83,000. Human narcolepsy is correlated with a greatly reduced number of Hcrt containing neurons and axons, and an elevated level of hypothalamic gliosis. Narcolepsy with cataplexy is characterized by a loss of approximately 90 % of Hcrt neurons. However, more than a quarter of narcoleptics do not have cataplexy and have normal levels of Hcrt in their cerebrospinal fluid. Narcolepsy without cataplexy has an overall a loss of 33 % of Hcrt cells compared to normal, with maximal cell loss in the posterior hypothalamus. A better understanding of the pattern of damage to Hcrt containing somas and axons and of the gliosis occurring in narcolepsy should clarify the nature of the pathological process responsible for this disorder.
I'm not sure my oldest son uses soap every time he showers. And I've seen our youngest son put soap on one hand and then instead of rubbing them together, stick the soapy hand immediately under the running water. Hopefully this simple, yet fun, experiment has convinced them of the merits of soap. The experiment is meant to simulate how soap helps to get rid of germs. What You Need plate (or saucer) with a raised edge water ground black pepper dishwashing liquid (we used Ms. Meyer's) What to Do Pour water onto the plate. You should use enough water to cover the whole bottom of the plate. Sprinkle several pinches of ground black pepper onto the water. Explain that these specks of peppers represent germs. Now squirt a dot of dishwashing liquid onto one of your index fingers. Rub it all around, completely covering the tip of the finger. Lastly, put your soap-covered finger into the middle of the peppered water. Be amazed. The soap seems to repel the pepper (aka the "germs"). Why it Works This activity was discovered on Fantastic Fun and Learning. As explained by Shaunna, "When soap is added to the water it lowers the surface tension of the water causing the water molecules on the surface to scatter or pull away from the point where you added the soap." What to Read You can't go wrong with a Magic School Bus Book. We have rediscovered our love for all things Frizzle this summer. This book complemented the activity beautifully!
