"If you take wolves and socialize them properly at a young age, and work with them on a daily basis, then yes, you can get them to be cooperative and attentive to humans," said Friederike Range, a researcher at the Messerli Research Institute at the University of Veterinary Medicine Vienna.

Read More »Scientific games of hide-and-seek have shown that tamed wolves can pick up on a human's hints as well as dogs can — adding yet another twist to the long-running debate over the domestication of man's best friend. The experiments at Austria's Wolf Science Center, described in Tuesday's issue of Frontiers in Psychology, support the view that wolves had a pre-existing capacity to learn from social partners — and that humans capitalized on that capacity more than 18,000 years ago. "If you take wolves and socialize them properly at a young age, and work with them on a daily basis, then yes, you can get them to be cooperative and attentive to humans," said Friederike Range, a researcher at the Messerli Research Institute at the University of Veterinary Medicine Vienna. Genetic analysis shows that dogs descended from gray wolves, and they're still so genetically similar that they're regarded as belonging to the same species, Canis lupus. But some researchers have suggested that dogs have a unique capacity for interaction with humans. Range and a colleague at the institute, Zsofia Viranyi, designed a series of food-hiding games to assess the social skills of 11 North American gray wolves as well as 14 dogs. All of the animals were between 5 and 7 months old, born in captivity, bottle-fed and hand-raised in packs. During each game, a dead chick was hidden in one of three locations in a park meadow. Sometimes the wolves and the dogs were allowed to watch while a human hid the snack. Sometimes the humans only pretended to hide it. And sometimes the canines watched while a dog looked around for the snack. Wolves hang out together at the Wolf Science Center in Ernstbrunn, Austria. Peter Kaut The wolves and the dogs were all roughly two to four times more likely to find the dead chick when they could see the human hide it. They rarely looked around for the chick when the human was only pretending — which suggests that they were picking up on the human's subtler hints. The dogs also caught on to the clues signaled by other dogs. But the wolves followed a different pattern: They didn't show as much interest in following up on the dogs' demonstration. Range and Viranyi suggest that this was merely because the wolves could tell that the dogs didn't care much for the dead chick once they found it. Range told NBC News that the findings ran counter to some previous claims about the special abilities of dogs. "There have been several hypotheses regarding domestication, including that there are some social skills dogs have that wolves don't, or that dogs can accept humans as social partners and wolves can't," she said. "The story is not that simple — this we can say for sure."

Read More »Fast Internet connections have a ping time of less than 2 ms (optical fibre), slow Internet connections may have ping times of over 50 ms (UMTS access); typically ping times range from 5 to 30 ms.
Ping (latency is the technically more correct term) means the time it takes for a small data set to be transmitted from your device to a server on the Internet and back to your device again. The ping time is measured in milliseconds (ms). The ping time is a very important indicator for online games, but for quite normal Internet surfing too the ping time has a considerable effect on the access delay time. The delay is critically influenced both by your Internet access technology and by its utilisation level. Note that ping refers to two-way latency (aka round-trip delay), a value relevant for Internet usage. Sometimes it is referred to "one-way latencies" which account only for the access part, but not for the transmission in the whole network. If you are accessing very far remote servers, the length of the transmission route also has a marked effect on the ping time (e.g. about 280 ms for Japan). Fast Internet connections have a ping time of less than 2 ms (optical fibre), slow Internet connections may have ping times of over 50 ms (UMTS access); typically ping times range from 5 to 30 ms.
