Man, 40, suffers concussion after diving into shallow pool

In 2006, Derek Amato suffered a violent head injury after he dived into the shallow end of a swimming pool. He lost his memory,  35 percent hearing loss in one ear and headaches. But he grew an extraordinary musical talent. Amato found out that he could all of a sudden play piano -- and he could do it well.

Amato writes in a blog post, ” As I close my eyes, I found these black and white structures moving from left to right, which in fact would represents a fluid and continuous stream of musical notation in my mind. My fingers started to play the piano keys as if I had done it all of my life. I can't explain the feeling of wonder that overpowered my entire being, although I can tell you the appearance on my friend's face were enough to put us both in tears."

Dr. Darold Treffert from University of Wisconsin School of Medicine identified that he is in a condition of "acquired savant syndrome" -- a condition where a mental impairment results in superhuman skills, according to Popular Science.
And so, the 39-year-old sales trainer from Denver decided to drastically change his life and became a professional pianist.

This past August, Amato told his story in a TED Talk. When asked what he would do if he suddenly lost his musical gift, he said that he would still be equally grateful for the experience.
"I've had seven years [with this syndrome]. Not too many people get to see this much life in seven years. I've been pretty lucky," he told HuffPost Live. "Hey, if it goes away, I've had seven beautiful years to enjoy it."

Amato is a father of three. He lives in Colorado and, when he’s not making music, he enjoys fly fishing and philanthropy.

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.

Evolution in Action: Lizard Moving From Eggs to Live Birth

A yellow-bellied three-toed skink carrying embryos, visible as light orbs inside its body.

Evolution has been caught in the act, according to scientists who are decoding how a species of Australian lizard is abandoning egg-laying in favor of live birth.
An Australian lizard can apparently either give live birth or lay eggs. This ability raises the question, is it evolution “caught in the act” (as National Geographic declares*), or is it an incredible ability explained within the creationist perspective?
In Australia’s warm coastal lowlands, a yellow-bellied three-toed skink lays eggs (like most reptiles), but in the colder mountains, most individuals of the same species give live birth.
Secularists speculate that the ability of different animals to give live birth evolved from oviparity (egg-laying). But before you jump to the conclusion that this flexibility among skinks hints at a way mammals may have evolved viviparity (live births), it’s important to remember the vast difference between skink births and mammal births. Skinks simply retain the eggs (that is, the shelled embryos) inside their bodies, while most mammals develop a special organ, called a placenta, rather than a shell.
So is this species of skink really “evolving” from egg-laying to live birth, as the National Geographic Daily Newsheadline states? On the contrary, this discovery showcases the fact that God designed some lizards with the ability to switch birth methods in response to environmental conditions.
Meanwhile, researchers have observed no sign that skinks (or other creatures) have acquired or are acquiring completely new physiologies or behaviors that weren’t already latent in them.
This remarkable adaptability is built into these skinks by their Creator, but it was apparently not revealed until they experienced the appropriate conditions (such as colder mountains). It is very likely that many traits are still stored away in God’s creatures. They just may need the right conditions to make them manifest.
