Earliest Case of Child Abuse Discovered in Egyptian Cemetery



When the researchers came across the abused toddler, labeled "Burial 519," in Kellis 2, nothing seemed out of the ordinary at first. But when they began brushing the sand away, they noticed prominent fractures on the child's arms. The excavated in situ burial of 519 shown here.
          A 2- to 3-year-old child from a Romano-Christian-period cemetery in Dakhleh Oasis, Egypt, shows evidence of physical child abuse, archaeologists have found. The child, who lived around 2,000 years ago, represents the earliest documented case of child abuse in the archaeological record, and the first case ever found in Egypt, researchers say.

         The Dakhleh Oasis is one of seven oases in Egypt's Western Desert. The site has seen continuous human occupation since the Neolithic period, making it the focus of several archaeological investigations, said lead researcher Sandra Wheeler, a bioarchaeologist at the University of Central Florida. Moreover, the cemeteries in the oasis allow scientists to take a unique look at the beginnings of Christianity in Egypt.

         In particular, the so-called Kellis 2 cemetery, which is located in the Dakhleh Oasis town of Kellis (southwest of Cairo), reflects Christian mortuary practices. For example, "instead of having children in different places, everyone is put in one place, which is an unusual practice at this time," Wheeler told LiveScience. Dating methods using radioactive carbon from skeletons suggest the cemetery was used between A.D. 50 and A.D. 450.

        When the researchers came across the abused toddler — labeled "Burial 519" — in Kellis 2, nothing seemed out of the ordinary at first. But when Wheeler's colleague Tosha Duprasbegan brushing the sand away, she noticed prominent fractures on the child's arms. 

Archaeologists discovered the remains of a toddler in Romano-Christian-period cemetery in Dakhleh Oasis, Egypt, who showed evidence of child abuse. Here, mud bricks for two tomb structures in the cemetery. In the foreground, several excavated graves can be seen.
"She thought, 'Whoa, this was weird,' and then she found another fracture on the collarbone," Wheeler said. "We have some other kids that show evidence of skeletal trauma, but this is the only one that had these really extreme fracture patterns."

Signs of abuse

The researchers decided to conduct a series of tests on Burial 519, including X-ray work, histology (microscopic study of tissues) and isotopic analyses, which pinpoint metabolic changes that show when the body tried to repair itself. They found a number of bone fractures throughout the body, on places like the humerus (forearm), ribs, pelvis and back.

Whereas no particular fracture is diagnostic of child abuse, the pattern of trauma suggests it occurred. Additionally, the injuries were all in different stages of healing, which further signifies repeated nonaccidental trauma.

One of the more interesting fractures was located on the child's upper arms, in the same spot on each arm, Wheeler said. The fractures were complete, broken all the way through the bone — given that children are more flexible than adults, a complete break like that would have taken a lot of force.

        After comparing the injury with the clinical literature, the researchers deduced that someone grabbed the child's arms and used them as handles to shake the child violently. Other fractures were also likely caused by shaking, but some injuries, including those on the ribs and vertebrae, probably came from direct blows.

       The archaeologists aren't sure what ultimately killed the toddler. "It could be that last fracture, which is the clavicle fracture," Wheeler said, referring to the collarbone. "Maybe it wasn't a survivable event."

       A unique case Child abuse in the archaeological record is rare. One possible reason, Wheeler said, is that archaeologists didn't really pay much attention to child remains until about 20 years ago, believing that children couldn't tell them much about the past.

       A few cases of possible child abuse have since come out of France, Peru and the United Kingdom, all of which date back to medieval times or later. "Certainly, our case has the best context in terms of the archaeology and skeletal analysis," Wheeler said. Of the 158 juveniles excavated from the Kellis 2 cemetery, Burial 519 is the only one showing signs of repeated nonaccidental trauma, suggesting child abuse wasn't something that occurred throughout the community. The uniqueness of the case supports the general belief that children were a valued part of ancient Egyptian society.

       By contrast, though Romans loved their kids immensely, they believed children were born soft and weak, so it was the parents' duty to mold them into adults. They often engaged in such practices as corporal punishment, immobilizing newborn infants on wooden planks to ensure proper growth and routinely bathing the young in cold water as to not soften them with the feel of warm water.

 "We know that the ancient Egyptians really revered children," Wheeler said. "But we don't know how much Roman ideas filtered into Egyptian society," she added, suggesting that the unique child abuse case may have been the result of Roman influence.

Softdrinks Tin can kill U..............Be Careful.


IMPORTANT:

SHOULD READ and do not ignore this message without SHARING.

On Sunday a family went to picnic with a few drinks tin. Monday, two family members admitted to hospital and placed in the Intensive Care Unit space. He died on Wednesday, Autopsy results concluded it hit Leptospirosis. The virus is stuck to the tin cans are drunk, without the use of glasses / cups. Test results showed that tin was infected mice that had dried urine containing Leptospira. Highly recommended to rinse the parts evenly on all soda cans before drinking it. Cans are usually stored in the warehouse and delivered direct to retail stores without cleaning. A study shows that the top of all beverage cans more contaminated than public toilets (full of germs and bacteria.)So, clean it with water before putting mouth in order to avoid all accidents total.

Use of Straws to drink can be one of the possible safety measure if u don't have water to clean the top of the tin.

Trouble Sleeping?

For those who have trouble sleeping researchers say that 1 week of camping, without electronics, resets our biological body clock and synchronizes our melatonin hormones with sunrise and sunset.

This story was originally published by Inside Science News Service.

Throughout most of human history, humans went to bed shortly after the sun went down and woke up in the morning as it rose. There were candles and later oil lamps, but the light was not very bright so people still went to bed early.
Then came Thomas Edison and the incandescent light bulb and everything changed, including our sleeping habits. So, if you have problems getting to sleep at night or are a miserable person to be around in the morning, blame him.
Scientists at the University of Colorado Boulder found that if you live by the sun's schedule, you are more likely to go to bed at least an hour earlier, wake up an hour earlier, and be less groggy, because your internal clock and external reality are more in sync. The sun adjusts your clock to what may be its natural state, undoing the influence of light bulbs. 
The work is published in the current issue of the journal Current Biology.
The disconnect between the outside environment and sleep is one reason why even native Alaskans have problems sleeping in the almost endless days of the Arctic summers, and get depressed during the long nights of winters.
The subjects in the Colorado study lived more normal lives.
"We weren’t studying people who had sleep difficulties," said Kenneth Wright, an integrative psychologist at Boulder. "The amount of sleep they got did not change. What changed was the timing of their sleep and the timing of their [internal] clock relative to when they slept."
The researchers took eight adults, average age around 30, and followed them around the normal course of their lives for a week. The subjects spent most of their time indoors while working, studying, eating, and sleeping. Most of the light they encountered was   artificial. Then, they sent the same people out camping.
Sleep and light were measured daily and the hormone melatonin every hour across 24 hours, once after the week of living at home, going to work, school, and then after a week of camping.
Melatonin is the "hormone of darkness," said Namni Goel, a psychologist and sleep researcher at the University of Pennsylvania in Philadelphia. Scientists use the hormone to measure photoperiods, or the physiological response that organisms have to cycles of daylight and darkness. 
"It rises at night naturally, and falls during the day, suppressed by light," said Goel.
Melatonin also drops the body’s core temperature, making it easier to sleep. People often take melatonin pills to help them fall asleep, she said.
After the week’s study indoors, the Colorado subjects went camping in the Rockies. Instead of artificial lighting, they had only sunshine during the day and campfires at night. Wright estimates the light from the sun was four times as intense as what they experienced indoors. The nature of the light also changed during the day. Think of the bright white light of midday and the golden glow that often precedes sunset.
After their week of camping, researchers measured the subjects' melatonin levels again.
The researchers found that the onset of melatonin shifted two hours earlier, and the subjects’ actual sleep shifted more than an hour earlier. Their bodies were recalibrating themselves, Wright explained.
When they woke in the morning in their normal lives, the melatonin and the external time were in conflict. They were waking up, but the melatonin in their bodies was telling them they should still be asleep. That might account for their still feeling sleepy, Wright said.
When they were out in the outdoors, the melatonin levels and the sun cycle were more aligned--the levels went down as the sun rose and before they woke up. They were subject to more light -- sunlight -- for the majority of the day.
The relationship between light and sleep and how much sleep a person needs has been the subject of several classic experiments.
Some involving putting subjects in deep, totally dark caves for weeks at a time have discovered that the 24-hour-day is almost exactly right for our bodies. The average amount of time our bodies consider a day comes to 24.3 hours, Goel said.
Goel and other Colorado scientists agree that the experiment was small, with only eight subjects, which limits what can be concluded. Nonetheless, the findings justify more experiments like it.
And more camping.
