Swedish Farmers Have Doubts About Climatologists and Climate Change
cold fjord (826450) writes with this excerpt from ScienceNordic: Researchers the world over almost unanimously agree that our climate is changing ... But many farmers – at least Swedish ones – have experienced mild winters and shifting weather before and are hesitant about trusting the scientists. The researcher who discovered the degree of scepticism among farmers was surprised by her findings. Therese Asplund ... was initially looking into how agricultural magazines covered climate change. Asplund found after studying ten years of issues of the two agricultural sector periodicals ATL and Land Lantbruk that they present climate change as scientifically confirmed, a real problem. But her research took an unexpected direction when she started interviewing farmers in focus groups about climate issues. Asplund had prepared a long list of questions about how the farmers live with the threat of climate change and what they plan to do to cope with the subsequent climate challenges. The conversations took a different course: "They explained that they didn't quite believe in climate changes," she says. "Or at least that these are not triggered by human activities."

TV Programmers Seek the Elusive Dog Market
HonorPoncaCityDotCom writes "Stanley Coren reports that a number of new television stations are providing programming specifically designed for dogs and while many people report that their dogs completely ignore what is visible on television, with modern resolution and quicker imaging, more dogs have become potential television viewers. The increase in dog viewership is primarily attributed to the way the dog's eye works. The image on a standard television screen is updated 60 times per second and since a human's flicker fusion frequency is only 55 Hz, the image appears continuous and the gradually changing images give us the illusion of movement. However dogs can discern flickers at up to 80 Hz so with the increased availability of high-resolution digital screens that are refreshed at a much higher rate, the images are less likely to appear to be flickering to the canine eye. Presentation factors are also an issue. Dogs are most likely to respond to images that have been captured at the eye level of a dog with a low camera angle where there are moving things like animals or birds. But even if that requirement is fulfilled, most dogs do not watch television because the TV is normally placed at a comfortable eye level for human beings and dogs do tend not to scan upward, and therefore do not notice the TV images. All of which brings us to DogTV, the first cable network to deliver 24-hour programming for dogs that lets you flip on the channel while you go out for the day as your pet is stimulated, entertained and relaxed. 'If the dog wasn't enjoying it, he would find something else to do, like nibble on the end of a sofa,' says veterinarian Ann E. Hohenhaus." -
Redheads Feel Pain Differently Than the Rest of Us
schwit1 writes "If you think redheads are inherently different, well, you'd be right; they're better than you. In fact, they have a higher pain threshold than most of us, and can handle spicier food, too. It turns out that gingers are less sensitive to stinging pain in the skin, according to researchers who injected capsicum, the active ingredient in chilies, into the arms of patients. Professor Lars Arendt-Nielsen, one of the researchers, said, 'Our tests showed that redheads are less sensitive to this particular type of pain. They react less to pressure close to the injected area, or to a pinprick. They seem to be a bit better protected, and that is a really interesting finding.' The finding also means redheads can handle spicier food, reports Science Nordic. It lends some scientific weight to previous suggestions that gingers have a different pain response to the rest of, which were even investigated by MythBusters."
