Sometime around 6000 BCE a nomadic herding people settled into villages in the Mountainous region just west of the Indus River. There they grew barley and wheat using sickles with flint blades, and they lived in small houses built with adobe bricks. After 5000 BCE the climate in their region changed, bringing more rainfall, and apparently they were able to grow more food, for they grew in population. They began domesticating sheep, goats and cows and then water buffalo. Then after 4000 BCE they began to trade beads and shells with distant areas in central Asia and areas west of the Khyber Pass. And they began using bronze and working metals.

The climate changed again, bringing still more rainfall, and on the nearby plains, through which ran the Indus River, grew jungles inhabited by crocodiles, rhinoceros, tigers, buffalo and elephants. By around 2600 BCE, a civilization as grand as that in Mesopotamia and Egypt had begun on the Indus Plain and surrounding areas. By 2300 BCE this civilization had reached maturity and was trading with Mesopotamia. Seventy or more cities had been built, some of them upon buried old towns. There were cities from the foothills of the Himalayan Mountains to Malwan in the south. There was the city of Alamgirpur in the east and Sutkagen Dor by the Arabian Sea in the west.

One of these cities was Mohenjo-daro (Mohenjodaro), on the Indus river some 250 miles north of the Arabian Sea, and another city was Harappa, 350 miles to the north on a tributary river, the Ravi. Each of these two cities had populations as high as around 40,000. Each was constructed with manufactured, standardized, baked bricks. Shops lined the main streets of Mohenjo-daro and Harappa, and each city had a grand marketplace. Some houses were spacious and with a large enclosed yard. Each house was connected to a covered drainage system that was more sanitary than what had been created in West Asia. And Mohenjo-daro had a building with an underground furnace (a hypocaust) and dressing rooms, suggesting bathing was done in heated pools, as in modern day Hindu temples.

The people of Mohenjo-daro and Harappa shared a sophisticated system of weights and measures, using an arithmetic with decimals. Whether these written symbols were a part of a full-blown written language is a matter of controversy among scholars, some scholars pointing out that this and the brevity of grave site inscriptions and symbols on ritual objects are not evidence of a fully developed written language.

The people of Mohenjo-daro and Harappa mass-produced pottery with fine geometric designs as decoration, and they made figurines sensitively depicting their attitudes. They grew wheat, rice, mustard and sesame seeds, dates and cotton. And they had dogs, cats, camels, sheep, pigs, goats, water buffaloes, elephants and chickens.

The story is set in the mid-21st century. Global warming has led to ecological disasters all over the world, and a drastic reduction of the human population. Mankind's efforts to maintain civilization lead to the creation of "mechas," advanced humanoid robots capable of emulating human thoughts and emotions. Among these androids there is an advanced prototype model named David, a mecha created by the Cybertronics company to resemble a human child and to "feel" love for its human owners. They test their creation on one of their employees, Henry Swinton and his wife Monica. The Swintons have a son, Martin, who has been placed in suspended animation until a cure can be found for his rare disease. Although Monica is initially frightened of David, she eventually warms to him after activating his imprinting protocol, which irreversibly causes David to feel love for her as a child loves a parent. As he continues to live with the Swintons, David is befriended by Teddy, a mecha toy, who takes upon himself the responsibility of David's well being.

Martin is suddenly cured and brought home; a sibling rivalry ensues between Martin and David. Martin's scheming behavior backfires when he and his friends activate David's self-protection programming at a pool party. Martin is saved from drowning but David's actions prove too much for Henry. It is decided for David to be destroyed at the factory where he was built, but Monica rather leaves him (alongside Teddy) in a forest to live as unregistered mechas. David is captured for an anti-mecha Flesh Fair, an event where useless mechas are destroyed before cheering crowds. David is nearly killed, but the crowd is swayed by his realistic nature and he escapes, along with Gigolo Joe (Jude Law), a male prostitute mecha on the run after being framed for murder.

The two set out to find the Blue Fairy, whom David remembers from the story The Adventures of Pinocchio. As in the story, he believes that she will transform him into a real boy, so Monica will love him and take him back. Joe and David make their way to the decadent metropolis of Rouge City. Information from a holographic volumetric display personality called "Dr. Know" eventually leads them to the top of the Rockefeller Center in the flooded ruins of Manhattan. David's human creator, Professor Hobby, enters and excitedly tells David that finding him was a test, which has demonstrated the reality of his love and desire. A disheartened David attempts to commit suicide by falling from a ledge into the ocean, but Joe rescues him, just as he is captured by the authorities.

David and Teddy take a submersible to the fairy, which turns out to be a statue from a submerged attraction at Coney Island. Teddy and David become trapped when the park's ferris wheel falls on their vehicle. Believing the Blue Fairy to be real, he asks to be turned into a real boy, repeating his wish without end, until the ocean freezes. 2000 years later, Manhattan is buried under several hundred feet of glacial ice, and humans are extinct. Mechas have evolved into an alien-looking humanoid form. They find David and Teddy: functional mechas who knew living humans. David wakes up and realizes the fairy was fake. Using David's memories, the mechas reconstruct the Swinton home, and explain to him via a mecha of the Blue Fairy that he cannot become human. However, they recreate Monica from a lock of her hair which has been faithfully saved by Teddy, but she will live for only a single day and the process cannot be repeated. David spends the happiest day of his life playing with Monica and Teddy. Monica tells David that she loves him and has always loved him as she drifts to sleep for her final time. This was the "everlasting moment" he had been looking for, he closes his eyes, falls asleep for his first time, and goes "to that place where dreams are born".

"You are Israel's teacher," said Jesus, "and do you not understand these things? I tell you the truth, we speak of what we know, and we testify to what we have seen, but still you people do not accept our testimony. I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things? No one has ever gone into heaven except the one who came from heaven—the Son of Man. Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up, that everyone who believes in him may have eternal life. "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son. This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.

Chemically, DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called bases. It is the sequence of these four bases along the backbone that encodes information. This information is read using the genetic code, which specifies the sequence of the amino acids within proteins. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription.

Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication. Eukaryotic organisms (animals, plants, fungi, and protists) store their DNA inside the cell nucleus, while in prokaryotes (bacteria and archaea) it is found in the cell's cytoplasm. Within the chromosomes, chromatin proteins such as histones compact and organize DNA. These compact structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.

Internet Protocol version 6 (IPv6) is the next-generation Internet Layer protocol for packet-switched internetworks and the Internet. IPv4 is currently the dominant Internet Protocol version, and was the first to receive widespread use. In December 1998, the Internet Engineering Task Force (IETF) designated IPv6 as the successor to version 4 by the publication of a Standards Track specification, RFC 2460.

In December 2008, despite celebrating its 10th anniversary as a Standards Track protocol, IPv6 was only in its infancy in terms of general worldwide deployment. A recent study by Google indicates that penetration is still less than one percent of Internet traffic in any country. The leaders are Russia (0.76%), France (0.65%), Ukraine (0.64%), Norway (0.49%), and the United States (0.45%). Although Asia leads in terms of absolute deployment numbers, the relative penetration is smaller (e.g., China: 0.24%). IPv6 is implemented on all major operating systems in use in commercial, business, and home consumer environments. According to the study, Mac OS X leads in IPv6 penetration of 2.44%, followed by Linux (0.93%) and Windows Vista (0.32%).

IPv6 has a much larger address space than IPv4. This results from the use of a 128-bit address, where IPv4 uses only 32 bits. The new address space thus supports 2^128 (about 3.4×10^38) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the need for network address translation (NAT). NAT gained widespread deployment as an effort to alleviate IPv4 address exhaustion.

IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the host identifier from Link Layer media addressing information (MAC address).

Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security (IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4 (into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a fundamental interoperability requirement.

The general requirements for implementing IPv6 on a network host are specified in RFC 4294.
