In their world, dogs rely mostly on their sense of smell to collect the information they need. Humans do that with their eyesight, as it is more developed. So, it is possible to say that dogs “see” the world with their noses, instead of using their eyes. What do you do when you ...
Dogs' noses are amazing. Not only are they up to 100 million times more sensitive than ours, they can sense weak thermal radiation — the body heat of mammalian (哺乳动物的) prey, a new study reveals. The find helps explain how dogs with damaged sight, hearing, or smell can still hunt...
Dogs and their powerful noses are known for finding people during search and rescue efforts, identifying the smell of drugs and even diseases like cancer. But the dog nose can also act like radar for other things that are hidden from our sight.Now, they're acting like watchdogs for endanger...
Researchers believe they have solved one of science's greatest mysteries. They think they have found out why a dog's nose is cold. Scientists from universities in Sweden and Hungary have posited that dogs' noses are constantly cold because they act as "ultra-sensitive heat detectors". Canines...
"Dogs have up to 300 million scent sensors in their noses, compared to humans, who only have 6 million," the American Kennel Club says on its website. While the encounter might be perfectly fine for the dog, you don't have to sit there while he sniffs away at their lower half. ...
可知,狗是利用它们的鼻子(noses)来寻找人侵性的物种的。故选A项。干扰项排除:body身体;head头部;advantage优点。这三个选项的范围相比较nose而言太广了。故排除它们。11.A 根据上文的“A 2010 study reported high success rates ofdogs”可知,此处指的是这个研究(study)发现了受过训练的狗能闻到并找到比人类能...

It’s not entirely surprising that dogs have super-powered noses when it comes to detecting human ailments. Our best animal buddies have been used to sniff out diseases likecanceranddiabetes“with some success,” the researchers note. The new study, however, not only shows that dogs can smell...
This would be a pre requisite for potential anticipation, either by electronic systems (e.g., e-noses) or trained dogs. The aim of the present study therefore was to test whether trained dogs, as demonstrated for cancer or diabetes, may discriminate a general epileptic seizure odor (different...
