Another look at those airport X-rays...
These questions have not been answered to any satisfaction and the UCSF scientists, all esteemed in their fields and members of the National Academy of Sciences have been dismissed based on a couple of reports seemingly hastily put together by mid-level government lab technicians. The documents that I have reviewed thus far either have NO AUTHOR CREDITS or are NOT authored by anyone with either a Ph.D. or a M.D., raising serious concerns of the extent of the expertise of the individuals and organizations evaluating these machines. Yet, the FDA and TSA continue to dismiss some of the most talented scientists in the country...
Furthermore, when making this comparison, the TSA and FDA are calculating that the dose is absorbed throughout the body. According the simulations performed by NIST, the relative absorption of the radiation is ~20-35-fold higher in the skin, breast, testes and thymus than the brain, or 7-12-fold higher than bone marrow. So a total body dose is misleading, because there is differential absorption in some tissues. Of particular concern is radiation exposure to the testes, which could result in infertility or birth defects, and breasts for women who might carry a BRCA1 or BRCA2 mutation. Even more alarming is that because the radiation energy is the same for all adults, children or infants, the relative absorbed dose is twice as high for small children and infants because they have a smaller body mass (both total and tissue specific) to distribute the dose. Alarmingly, the radiation dose to an infant's testes and skeleton is 60-fold higher than the absorbed dose to an adult brain!
"What happens to a chromosome of a normal cell when it is exposed to radiation. It most cases, this damage is repaired; however, at high doses or when there is a genetic defect, the cells either die or become cancerous."

Traveling with Food or Gifts
How to Pack Food and Gift ItemsWhen it comes to bringing items through checkpoints, we've seen just about everything. Traveling with food or gifts is an even bigger challenge. Everyone has favorite foods from home that they want to bring to holiday dinners, or items from their destination that they want to bring back home.
Not sure about what you can and can't bring through the checkpoint? Here's a list of liquid, aerosol and gel items that you should put in your checked bag, ship ahead, or leave at home.
Cranberry sauce
Cologne
Creamy dips and spreads
(cheeses, peanut butter, etc.)
Gift baskets with food items
(salsa, jams and salad dressings)
Gravy
Jams
Jellies
Lotions
- Maple syrup
- Oils and vinegars
- Perfume
- Salad dressing
- Salsa
- Sauces
- Snowglobes
- Soups
- Wine, liquor and beer

Charlie Rangel - guilty as charged...
Charlie Rangel, the 20-term Congressman from New York, was found guilty on a host of ethics violations today. Rangel, long-known to be a "dirty" pol, will now go down in the books for his misdeeds in office.
And that's a shame.
First, every member of Congress has the distinct opportunity to help his/her constituents in ways that almost no one else can. Holding office as a Representative is an honor and a privilege. Turning one's back on that in order to self-enrich/empower is criminal...and worse.
Second - and here's the really sad news - Rangel was a hero in the Korean War.
"During the Korean War, he was a member of the all-black 503rd Field Artillery Battalion in the 2nd Infantry Division. In late November 1950, this unit was caught up in heavy fighting in North Korea as part of the U.N. forces retreat from the Yalu River. In the Battle of Kunu-ri, Rangel was part of a vehicle column that was trapped and attacked by the Chinese Army. In the subzero cold, Rangel was injured by shrapnel from a Chinese shell. Some U.S. soldiers were being taken prisoner, but others looked to Rangel, who though only a private first class had a reputation for leadership in the unit. Rangel led some 40 men from his unit, during three days of freezing weather, out of the Chinese encirclement; nearly half of the battalion was killed in the overall battle. Rangel was awarded a Purple Heart for his wounds and the Bronze Star with Valor for his actions in the face of death. His Army unit was awarded the Presidential Unit Citation, the Republic of Korea Presidential Unit Citation, and three battle stars." (h/t: Wikipedia)
Today's obvious findings will be an unfitting conclusion to a political career that could have been great...as well as to a legacy of military leadership and heroism that was...

Big green lies...
"Despite a $535 million loan guarantee from the federal government, Solyndra, a maker of solar panels in the southeast San Francisco Bay Area city of Fremont, will close one of its manufacturing plants, lay off 40 permanent and 150 contract workers, delay expansion plans of a new plant largely financed with the government-guaranteed loan and scale back production capacity more than 50 percent. Despite the hype and tax money, Solyndra seems unable to compete with Chinese manufacturers, whose prices are lower. This is the latest bad news for the company touted by Mr. Schwarzenegger and President Barack Obama as one of the green industry’s supposed shining lights." – Editorial, The Orange County Register, November 11, 2010.
