4 Cool Fact Can Be Revealed from DNA
Friday, May 16, 2014
Since the discovery 60 years ago, deoxyribonucleic acid (DNA) has been used to uncover a lot of things, ranging from biological attachment between father and child or children with the mother to prove whether a person can be accused of committing a particular crime or not.
But probably not many know if DNA testing not only reveal things like that alone. Here are four cool facts can be revealed only on DNA testing as quoted by CNN.
1. Mapping the family tree
Who would have thought if you may still have a blood relationship with the leading celebrities? You can figure it out just by doing a DNA test.
No need to bother, sites like Ancestry.com are willing to compare your DNA with DNA recording various people around the world, hoping to hook you up with a family tree that you never knew before.
Not only that, Ancesty.com can also provide information about your genetic ethnicity.
"We can observe the massive amounts of DNA ... and compare it with other DNA samples from all over the world. Then to detect similarities that exist, we can trace back generations before you and connect you to your ancestors," writes the site The.
2. Solve an ancient mystery
Recently managed a team of archaeologists discovered the skull of one of the famous king of England that Richard III which was buried under a parking lot in Leicester. But investigators did not immediately believe it is a skull Richard III to DNA extracted from the bones of the king proved a match with Michael Ibsen, a direct descendant of the sister of Richard III.
This is not the first time the ancient relics can be identified thanks to DNA. The problem, though weather conditions were stored in a cool, dry and dark, DNA can last a long time, even up to thousands of years.
In 2009, DNA analysis of bone fragments prove that the two children of Czar Nicholas II was killed along with his entire family during the Russian Revolution, though so far there is speculation that the two managed to escape.
The scientists also succeeded in extracting DNA from ancient humans who have been extinct since the Neanderthals 30,000 years ago and the findings are expected to provide in-depth insight on the process of human evolution.
3. Predicting the future
By using a blood sample from the mother and saliva from the father, scientists can determine if their child is still in the womb will have a chromosome abnormality that can lead to genetic disorders such as Down Syndrome or not.
Later, the researchers also began to expand the functions of the prenatal genetic tests to identify potential developmental delays and intellectual disabilities such as autism in children.
Even genetic tests can also reveal certain health risk factors that you may have inherited from your parents, for example, the risk of breast cancer or colon cancer.
Although the determination of risk factors through genetic testing is no guarantee you are exposed to the disease, at least you know if you are likely to develop a certain disease. On the other hand, knowing the high risk such as this can encourage you to take some preventive measures.
4. Help you lose weight
According to a study, a persons ability to lose weight or otherwise established or determined by the genes you have.
The researchers themselves have identified several gene variants that may affect a persons potential for obesity, even down to their children. Studies in mice also ensure that 80 percent of body fat is regulated by genes.
"Although have found a genetic component that makes us prone to obesity, in fact, our understanding of this fact is very limited," said a diet and fitness expert Dr. Melina Jampolis.
From there, the researchers tried to figure out how to combine genetic factors, setting nutrition (diet) and exercise to help people lose weight and keep it off.

Ways To Cool Down Your Body Useful Exercises
Monday, February 10, 2014
At the end of an exercise session, leave enough time to cool
down to bring your heart rate, breathing, and temperature
nearer normal (failure to do so can lead to dizziness,
cramps, and soreness next day).
Slowing Heart Rate: Bring body temperature back to normal by
walking around the room for 5 minutes, gradually making your
movements slower as your heart rate returns to normal. This
helps return blood circulation to the organs and brain, guarding
against fainting and dizziness. When you no longer feel sweaty
or out of breath, move on to stretching.
Stretch Your Legs: Stand facing a wall, one foot a good step behind
the other. Press into the wall, front knee bent, and feel a stretch through
the back heel. Place the ball and toes of the front foot on the wall and
bend that knee to stretch the lower calf. Take the same foot to its buttock
and hold, knees together. Turn your back to the wall, extend the same leg
forward (toes raised), bend the standing leg and pivot forward to feel
stretch at the back of the thigh. Repeat on the other leg.
Ball Squeeze: Keep a small rubber ball on your desk or beside the bed.
Squeeze it in your palm for up to a minute twice a day to exercise
your hands.
Finger Mobility: Using the palm of one hand, gently press the back
of the fingers of the other hand toward the inner arm and hold.
Opening the palm, draw the fingers back, trying to take them
toward the forearm. Repeat with the thumb. Repeat on the other hand.
Spread Your Toes: Remove your shoes and socks. Look at your toes.
Lift them and try to stretch each digit away from its neighbors.
Aim for a gap between each toe. It can help to spread the fingers wide
as you practice.
