The E-Accountability Foundation announces the

'A for Accountability' Award

to those who are willing to whistleblow unjust, misleading, or false actions and claims of the politico-educational complex in order to bring about educational reform in favor of children of all races, intellectual ability and economic status. They ask questions that need to be asked, such as "where is the money?" and "Why does it have to be this way?" and they never give up. These people have withstood adversity and have held those who seem not to believe in honesty, integrity and compassion accountable for their actions. The winners of our "A" work to expose wrong-doing not for themselves, but for others - total strangers - for the "Greater Good"of the community and, by their actions, exemplify courage and self-less passion. They are parent advocates. We salute you.

Winners of the "A":

Johnnie Mae Allen
David Possner
Dee Alpert
Aaron Carr
Harris Lirtzman
Hipolito Colon
Larry Fisher
The Giraffe Project and Giraffe Heroes' Program
Jimmy Kilpatrick and George Scott

Space Travel Changes Our Genes, and NASA's Twin Study Proves It
The first-of-its-kind opportunity to study the genetic impact of space on the human body came about after astronaut Scott Kelly was chosen to serve aboard the International Space Station from March 2015 to March 2016. His identical twin, Mark Kelly, who is also a former NASA astronaut, remained on Earth.

Before you purchase your ticket to ride a spaceship to our space for your birthday, honeymoon, or something else, you should think about the changes that will occur to your DNA.

Really. NASA has confirmed that space travel impacts our genes.

Space travel changes our genes, and NASA's Twin Study proves it
MICHAEL D'ESTRIES, February 18, 2019

NASA has confirmed its preliminary findings from its year-long Twins Study, and the results have some scientists scratching their heads.

The first-of-its-kind opportunity to study the genetic impact of space on the human body came about after astronaut Scott Kelly was chosen to serve aboard the International Space Station from March 2015 to March 2016. His identical twin, Mark Kelly, who is also a former NASA astronaut, remained on Earth.

During the course of NASA's year-long mission aboard the International Space Station (ISS), researchers from 12 universities analyzed biological samples from both brothers to gauge the genetic shifts that might be taking place.

Their DNA is no longer the same
While most of the biological changes that Scott experienced in space returned to normal shortly after landing back on Earth, some of his DNA was altered.

Researchers discovered that 7 percent of his genes experienced long-term changes. Those genes correlate with his immune system, bone formation, DNA repair, hypoxia (deficiency in oxygen reaching tissues) and hypercapnia (excess carbon dioxide in the bloodstream).

Space changes how genes are expressed
Results from the study revealed that space travel causes an increase in methylation, the process of turning genes on and off, according to NASA. The change in gene expression caused many of the genes related to Kelly's immune system to become hyper activated and even shed mitochondrial DNA fragments into his bloodstream. Researchers aren't sure why the mitochondrial DNA freed itself from cells, but they believe it could be the body's way of coping with stress.

"Some of the most exciting things that we've seen from looking at gene expression in space is that we really see an explosion, like fireworks taking off, as soon as the human body gets into space," Twins Study principal investigator Chris Mason said in a statement. “With this study, we’ve seen thousands and thousands of genes change how they are turned on and turned off. This happens as soon as an astronaut gets into space, and some of the activity persists temporarily upon return to Earth.”

Time in space affects telomere length
The most surprising part of the study so far has to do with telomeres. These are essentially caps at the end of DNA that protect our chromosomes. They are thought to be tied to aging, since the length of our telomeres both decrease as we get older and are impacted by such factors as stress, smoking, lack of exercise and a poor diet.

Before the study, scientists speculated that the stress of space living would cause Scott's telomeres to shrink in comparison to his brother's. Instead, much to their surprise, the telomeres in Scott's white blood cells actually grew.

"That is exactly the opposite of what we thought," Susan Bailey, a radiation biologist at Colorado State University who is working with NASA to study the effect of space on telomeres, told Nature.

Once Scott returned to Earth, his telomeres quickly returned to their pre-mission levels. NASA speculates that the increase may have something to do with the low-calorie diet and strict exercise regimen Scott adhered to while on-board the ISS.

It also affects your arteries
NASA wanted to know if being in space for an extended period of time would affect an astronaut's arteries and blood circulation. Scott and Mark regularly submitted blood and urine samples, and ultrasounds were taken of their arteries. Tests showed that Scott's carotid artery wall was thickened and he had increased inflammation — even immediately after landing back on Earth.

However, it's still too early to say if Scott's condition is reversible or if being in space for that long permanently has accelerated the progression of atherosclerosis — buildup of fatty deposits in arteries.

Time in space affects telomere length

And it changes your gut, too
Other findings of note included a shift in the ratio of two dominant species of gut bacteria in Scott Kelly. While in space, one species dominated over the other. Back on the ground, however, the ratio returned to normal. Researchers performing genome sequencing on the twins also found more than 200,000 RNA molecules that were expressed differently between the twins. Current theories as to why this is happening range from the effects of microgravity to the simple act of eating freeze-dried food for 340 consecutive days.

And then there's the mystery of DNA methylation, a process that governs chemical modifications to DNA. While in space, Scott's methylation levels decreased. Over the same time on Earth, Mark's levels did the complete opposite. According to NASA, such results may indicate "genes that are more sensitive to a changing environment whether on Earth or in space."

Your immune system stays protected
The twins both took the flu vaccine at one-year intervals, and tests show that they both had an increased cell response to the flu — meaning the vaccine was working in protecting them from contracting the flu.

Therefore, NASA concluded that the flu vaccine has the same effects in space as it does on Earth. This finding gives hope that astronauts can be vaccinated and protected against contracting other viruses and diseases while in space for long periods of time.
