Photographer William Wegman is known for his dog photogrpahy - particularly of his Weimeraners. The fashion line Trussardi has him shooting their spring/summer 2014 collection with greyhounds - as Jheri says "thin and long legged"...
Internet connectivity is widespread and the notion of what the Internet and access is happens to be very different from the Silicon Valley vision. From Iain Marlow at The Globe and Mail.
Let me be even more clear: The Internet already exists in Africa! With few exceptions, no matter where I went in Ghana, I got wireless service – and was even able to tether my laptop to my BlackBerry. All of these experiences, as well as quickly signing up for a pre-paid wireless service in nearby Nigeria, make me deeply skeptical about the much-hyped attempts by massive Western corporations to “bring” Internet service to Africans. Google is planning on floating balloons over unconnected parts of the continent. And now Facebook, according to Techcrunch, is looking at buying a drone company called Titan Aerospace to do much the same thing: Toss up solar-powered unmanned flying craft that will beam down Internet to remote areas – like something out of a remake of The Gods Must Be Crazy.
Now, there are several things that strike me about this.
First: I don’t trust people in Silicon Valley to tell me what’s happening elsewhere in California, let alone what’s happening (or should be happening) in Africa. The steady stream of idiotic products that accompanies every sliver of innovation from the tech world is evidence enough of this. But every once in a while, international aid in the form of technology metastasizes into something particularly stupid – like Kony2012– and the ideas gain outsized attention (and funds and credence) by playing on simplistic assumptions by people who know absolutely nothing about the situation on the ground. There are thousands of smart Africans already working in technology in Africa, and doing amazing things, and I don’t hear many of them talking about balloons and drones (except those other sorts of drones).
Again, don’t get me wrong. If this enfranchises people with connectivity that they never had before (and can actually utilize), then this could be a great opportunity – either for Facebook and Google to provide the connectivity on their own, or to startle carriers on the ground into extending service deeper into rural areas, more rapidly, thereby achieving the same thing. But we’ve heard ideas like this before, and they almost never turn out to be more than a catchy headline. And this time it’s coming from companies that are trying to convince the financial markets that there is growth out there, beyond the hills in the places where none of them have ever travelled – in the lands where people use WhatsApp.
Seventy-four years ago, Russia accomplished what no country had before, or has since—it sent armed ground robots into battle. These remote-controlled Teletanks took the field during one of WWII’s earliest and most obscure clashes, as Soviet forces pushed into Eastern Finland for roughly three and a half months, from 1939 to 1940. The Finns, by all accounts, were vastly outnumbered and outgunned, with exponentially fewer aircraft and tanks. But the Winter War, as it was later called (it began in late November, and ended in mid-March), wasn’t a swift, one-sided victory. As the more experienced Finnish troops dug in their heels, Russian advancement was proving slow and costly. So the Red Army sent in the robots.
Specifically, the Soviets deployed two battalions of Teletanks, most of them existing T-26 light tanks stuffed with hydraulics and wired for radio control. Operators could pilot the unmanned vehicle from more than a kilometer away, punching at rows of dedicated buttons (no thumbsticks or D-pads to be found) to steer the tank or fire on targets with a machine gun or flame thrower. And the Teletank had the barest minimum of autonomous functionality: if it wandered out of radio range, the tank would come to a stop after a half-minute, and sit, engine idling, until contact was reestablished.
Asteroids don't have enough enough mass for gravity to pull them into a spherical shape. The smaller ones, in particular, can be very loosely bound. Here the Hubble Space telesocpe catches one in the process of breaking up with the pieces slowly drifting away.. It is unlikely to be the result of a collsion - that would have been much more dramatic. Rather it is likely that a spin was induced by the pression of sunlight and that was enough for a breakup.
The answer lies, he thinks, in what the scans also revealed: Striking similarities in how dog and human brains process emotionally laden sounds. Happy sounds, such as an infant’s giggle, made the primary auditory cortex of both species light up more than did unhappy sounds, such as a man’s harsh cough. “It shows that dogs and humans have similar brain mechanisms for processing the social meaning of sound,” Andics says, noting that other research has shown that dogs “respond to the way we say something rather than to what we say.” The similarity in auditory processing, he adds, “helps explain why vocal communication between the two species is so successful.”
But there were differences, too. The researchers discovered that in dogs, 48% of their auditory brain regions respond more strongly to environmental sounds, such as a car engine, than to voices. In humans, in contrast, a mere 3% of their sound-sensitive brain regions lit up more for the nonvocal sounds. “It shows how very strongly attuned the human auditory cortex is to vocal sounds,” Andics says. “In dogs, it’s more heterogeneous.”
When the researchers mapped the brain activity of the participants, they found something astonishing. The generally accepted model of the brain contains regions devoted to each sense, such as the sight-centric visual cortex. Researchers had long believed that if those regions aren’t used for their intended sense, they are repurposed for other uses; for example, the visual cortex of someone blind from birth could be used to help boost her hearing. But Amedi and his colleagues found that the area of the visual cortex responsible for recognizing body shapes in sighted people—called the extrastriate body area—lit up with activity in the study participants when they were interpreting the human silhouettes.
Amedi says the traditional sensory-organized brain model can’t explain this activity; after all, the subjects only heard the information, and scientists believed that the body-recognizing area shouldn’t have fully developed without visual experiences during development. Neuroscientist Ella Striem-Amit of Harvard University, who co-authored the paper, thinks it’s time for a new model. “The brain, it turns out, is a task machine, not a sensory machine,” she says. “You get areas that process body shapes with whatever input you give them—the visual cortex doesn’t just process visual information.”
There is even information on an updated program and an iPhone app.
