Medical Myths Even Doctors Believe

ScienceDaily (Dec. 21, 2007) — Indiana University School of Medicine researchers explored seven commonly held medical beliefs. selected seven medical beliefs, espoused by both physicians and members of the general public, for critical review. They then searched for evidence to support or refute each of these claims.

People only use 10 percent of their brains

Hair and fingernails continue to grow after we die

Eating turkey makes you sleepy

People should drink at least eight glasses of water a day

Shaving hair cause it to grow back faster or coarser

Reading in dim light ruins your eyesight

Until someone takes the time to question and look for evidence, medical myths will remain accepted beliefs.

Canyonero Country

NASA's Mars Exploration Rover Opportunity snapped this approximate true-color picture of a promontory nicknamed "Cape Verde" with its panoramic camera, more than a month after beginning its descent down the walls of Victoria Crater.

The image's soft quality and "haze" in the lower right portion resulted from dust on the front sapphire window of the rover's camera.

Brain Differences Found In Creative Problem Solvers

A new study

reveals a distinct pattern of brain activity, even at rest, in people who tend to solve problems with a sudden creative insight -- an “Aha! Moment” – compared to people who tend to solve problems more methodically.

the creative solvers exhibited greater activity in several regions of the right hemisphere.

The current study shows that greater right-hemisphere activity occurs even during a “resting” state in those with a tendency to solve problems by creative insight. This finding suggests that even the spontaneous thought of creative individuals, such as in their daydreams, contains more remote associations.

creative and methodical solvers exhibited different activity in areas of the brain that process visual information. The pattern of “alpha” and “beta” brainwaves in creative solvers was consistent with diffuse rather than focused visual attention

NASA Images of CaliforniaWildfires

In addition to the dangers that a wildfire’s flames pose to people, wildlife, and property, the smoke that they billow out poses a health hazard over an even larger area. During the fires in Southern California during the fourth week of October, the air quality deteriorated to levels that the Environmental Protection Agency categorizes as “unhealthy” in many areas.

This series of images shows the spread of smoke between October 25-27, as tracked by the Ozone Monitoring Instrument on NASA’s Aura satellite. OMI measures how much the smoke particles impede light passing through the atmosphere. Places where smoke particles (aerosols) were thickest are colored pink; relatively clear air is transparent, and clouds are white.

The image shows the fire burning around Ramona, California, north of downtown San Diego. Flames glow red, yellow, and orange in the infrared-enhanced image, and plumes of smoke are faintly visible traces of blue

Rats fed tart cherries as 1 percent of their total diet had reduced markers of metabolic syndrome

anthocyanin-containing whole foods

By the end of the study, the rats that received the 1-percent cherry diet had total cholesterol, triglyceride, glucose and insulin levels that were significantly lower than those of the rats that did not receive cherries. The same was true for those on the 10-percent cherry diet, compared with rats that received a diet with an equivalently high level of carbohydrates not from cherries

rats that received cherries had both a lower level of fat in their livers

Former President Carter says President Bush's administration is "the worst in history" in international relations

Carter came down hard on the Iraq war

We now have endorsed the concept of pre-emptive war where we go to war with another nation militarily, even though our own security is not directly threatened, if we want to change the regime there or if we fear that some time in the future our security might be endangered,"

How to Create Passion for (Almost) Anything

Wed, 24 Oct 2007 20:46:00 GMT

clipped by: AndreaJoRush
clipper's remarks: Good tips

Clip Source: www.pickthebrain.com

There’s a big myth in our culture: that passion can only be spontaneous.

I disagree. Passion can be created. Even for things you don’t currently enjoy.

The benefit is that you end up loving the things you have to do anyways.

Here are some ways to find your passion:

Get Curious

begin from the view that you are almost completely ignorant on the subject. Then look for novelty to boost your interest.

Make it a Game

Set a Goal

Express Yourself

View each activity as an act of expression and originality.

Focus

Jigsaw Piecing

View your activities as pieces of a larger image

Dial Down Cravings

The more you crave a goal (instead of the process containing the goal) the less likely you are to develop a passion for it. Goal-setting is good. Goal-obsession is not.

Connect with Talents

apply your existing talents

Overcome the Frustration Barrier

slow down

build up skill

Leech Enthusiasm

spend time with someone who exudes passion

Remove the Chains

Tune the Challenge

Get instruction

Humble confidence

Play

Antarctica Has Most of World's Fresh Water

The southernmost continent has roughly 90 percent of the world's ice, which amounts to nearly three quarters of the Earth's fresh water being locked away there. This has led some to float the idea of towing icebergs to quench dry, drought-stricken areas. In fact, Prince Mohammed al Faisal of Saudi Arabia once considered a plan to find a 100 million-ton iceberg off Antarctica and tow it to the Arabian peninsula.

An artificial tornado swirls inside at the Mercedes-Benz Museum in the southern German town.

The 113-foot-long (34-meter-long) twister was created using the museum's smoke ventilation system, which was actually installed to suck out air if a fire started.

Guiness World Records has certified that the German feat is the world's largest human-made tornado.
