From left to right: Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that YouTube was founded after a dinner party “was probably very strengthened by marketing ideas around creating a story that was very digestible”. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November Universal Tube has since changed the name of its website to www. According to YouTube, this was the first worldwide free online broadcast of a major sporting event. Google product manager Shiva Rajaraman commented: The app is designed to provide an experience optimized for children.
Would You Wear a Kombucha Dress? Neanderthals’ mysterious disappearance from the fossil record has long puzzled scholars who wondered whether the species went extinct on its own or was helped on its way out by Europe’s first modern human migrants. The new fossil dating suggests that Neanderthals died out in isolated patches across western Europe, with small areas overlapping in mosaic fashion for thousands of years with the arrival sites of the first modern humans there.
A doughty branch of the early human family, Neanderthals were big-brained and thick-boned hunters who once ranged from Spain to Siberia.

Characteristics[ edit ] Traditional military values of bravery, sacrifice, sense of duty, and camaraderie are emphasized, and the action is usually described from the point of view of a soldier. In some stories, however, technology is fairly static, and weapons that would be familiar to present-day soldiers are used, but other aspects of society have changed.
For example, women may be accepted as equal partners for combat roles.

A woman follows the noise, picking over the rocky terrain with a small canister tucked under an arm. Fast-forward a few months to a boutique on Rodeo Drive in Beverly Hills, where a sales associate passes a cashmere sweater over a scanner attached to the register. It displays the date and location that the cashmere was marked that morning in Mongolia along with the factory where the wool was processed and even the date the sweater arrived stateside.
It provided the perfect conditions for a boon in fakes. Simultaneously, supply chains have grown less reliable: Overseas, lower cost production with less scrupulous oversight allows leakage and extra shifts in the same factories. Added to this, the boom in e-commerce has created a new platform on which to sell those counterfeits, often unchecked. Much of that money was allocated to discreet new ways to protect their brand equity and reassure their loyal customers, like the science used in that cashmere sweater.
A unique sequence is created for each customer and is held in its database; against it any product can be subsequently tested. Currently, the system involves swabbing a product with a Q-tip and then sequencing the solution in a machine or dabbing it onto a solution that will glow red if synthetic DNA is present. The firm aims, though, to create near-instant scanning, like the device in that futuristic Rodeo Drive boutique.
Its scientists tried, unsuccessfully, for more than a year to either re-engineer it or move the DNA to another surface. For firms in the luxury sector, Wan continues, the compelling use for this technology lies in policing and controlling supply chains.

In addition, the radiation emissions would have increased the level of carbon isotopes in the Shroud, which would make it appear younger. The Shroud has attracted widespread interest ever since Secondo Pia took the first photograph of it in which showed details which could not be seen by the naked eye. Last year scientists at the University of Padua in northern Italy dated it to between BC and AD — still hundreds of years after Christ, who is believed to have died between AD.
Other scientists have previously suggested that neutron radiation may have been responsible for the ghostly image of a crucified man with his arms crossed.

Print Scientists can select from many techniques of radiometric dating to determine the age of artifacts as well as the age of Earth itself. Radiocarbon dating is used for dating once-living matter less than 40, years old, like wood and charcoal. Uranium dating techniques are used for dating objects from thousands to billions of years old. Both techniques rely on the properties of radioactive isotopes, which are unstable elements that decay into stable ones over time.
In the early decades of the twentieth century, scientists first developed an understanding that certain elements are radioactive and that these unstable isotopes decayed — or lost particles from their nuclei, thus becoming different elements — at a constant rate over time. Knowing a radioactive isotope’s decay rate, a scientist can say that after a given amount of time, half of the atoms in a radioactive “parent” sample will be transformed into its stable “daughter” product.
After another equal amount of time, half of the remaining radioactive atoms will decay. This is what is meant by “half-life. Because of its slow rate decay, uranium is commonly used to establish the ages of some of the oldest objects discovered in the earth, including the age of the planet itself. Uranium was incorporated into the earth on its formation.
Once fixed in solid rock, its supply of atoms cannot be replenished. Therefore, measuring the amount of the daughter product, lead , relative to the parent uranium , can help scientists establish the age of a rock sample.
