Now Man's Best Friend Is Men's Best Virus Finder

The 'Dog" which can do so many things from guiding the blind, find people trapped in snow or mud.  They serve in Hospitals and they help us with our depression. They do the best they can to keep us happy with a permanent smile. With big eyes that always look straight at you to ask for love, warn you of danger or even to beg for a snack. 
Now there is more thing they can do. Are you surprised?

 Dogs' olfactory capacity — they can sniff in parts per trillion — primes them to detect disease.Kayla Dear/Getty Images/EyeEm

As the owner of a yellow lab named Gus, author Maria Goodavage has had many occasions to bathe her pooch when he rolls around in smelly muck at the park.
Nevertheless, her appreciation for his keen sense of smell has inspired her to write best-selling books about dogs with special assignments in the military and the U.S. Secret Service.
Her latest, Doctor Dogs: How Our Best Friends Are Becoming Our Best Medicine,highlights a vast array of special medical tasks that dogs can perform — from the laboratory to the bedside, and everywhere else a dog can tag along and sniff. 
Canines' incredible olfactory capacity — they can sniff in parts per trillion — primes them to detect disease, and their genius for observing our behavior helps them guide us physically and emotionally.
Goodavage spoke with NPR contributor John Henning Schumann, a doctor and host of Public Radio Tulsa's #MedicalMonday about what she has learned about dogs in medicine 
This interview has been edited for clarity and length.
What led you to look into dogs in medicine?
I've been reading and writing about military dogs and Secret Service dogs for many years now, and it was sort of a natural next step. These are dogs on the cutting edge of medicine. They're either working in research or right beside someone to save their life every day. And really, doctor dogs are, for the most part, using their incredible sense of smell to detect diseases. And if they're paired with a person, they bond with that person to tell them something that will save their life. You reported on dogs doing this kind of work all over the world.
Yes, I did go around the world. The first doctor dogs I learned about were in Japan. There's a village about five hours north of Tokyo where scientists were doing some research among a population that has a very high level of stomach cancer. And I wanted to find the best of the best, cutting-edge medical dogs around the world. It was really fun to see these services and research dogs working with their people and how good they are. They're incredibly good at detecting disease.
You also report on dogs that can detect ovarian cancer, which is personal for you.
I do have skin in this game, actually, because unfortunately, we have ovarian cancer in the family. My mom died of it.
With ovarian cancer, there's not much great testing for early detection. I heard about these dogs at the University of Pennsylvania Veterinary Working Dog Center that are able to smell ovarian cancer. They're able to detect it as early as stage one. We're not even talking tumors here. They're able to detect ovarian cancer in one drop of plasma from a woman with ovarian cancer. 
The fact that the dogs can do this is exciting to me, and I think for so many people who have hard-to-detect cancers in the family.
What the dogs are doing now is remarkable and it's because their sense of smell is so keen. They can sniff in parts per trillion. They can detect a tablespoon of a substance, like a packet of sugar, in two Olympic-sized swimming pools. Humans have six million olfactory receptors and dogs have up to 300 million. So their noses are really primed.
Another area in which dogs excel in the clinical world is for patients with diabetes.
Yeah. It's amazing. We don't know what the dogs are smelling, but the trainers are training the dogs on the scent of hypoglycemia and also hyperglycemia. The dogs are somehow able to put it together and tell the person 15 or maybe 20 minutes before the person's devices even say, 'Hey, you're going into the low range!' because the dogs detect this in real time. So the person has an extra bit of time to do what they need to do, take glucose or whatever.
I was fascinated to learn that doctor dogs may also have a role in detecting so-called "superbugs," that is, antibiotic-resistant microbes.
Yes. Actually, there are three or four of these dogs working in a hospital in Vancouver who is sniffing out C. diff, which is one of those superbugs that can easily spread in vulnerable populations in hospitals and manifests in diarrhea and all kinds of issues that can actually kill people. And these dogs are stopping it in its tracks. Researchers have found that where these dogs work, the rates of C. diff really diminish. I hung out at this hospital one day and I just watched one of the dogs do his rounds, and he found what seemed to be C. diff -- and before I knew it, they had a whole cleaning team.
How do dogs help people suffering from PTSD?
There are people from the military, war veterans and active-duty soldiers even who are suffering from PTSD and who have gotten service dogs who, again, have been game-changers. They save lives. 
One of the dogs I learned about was placed with a soldier who had been to Iraq twice. He had PTSD and his life was falling apart. His marriage, his health, everything. He was on a cocktail of drugs. It made him a zombie. He hated that feeling. And one day someone told him about doctor dogs for PTSD.
He ended up getting one. Now if he's feeling anxious, he'll say, like, "snuggle" and the dog will just come in for a big hug, or another of various commands. His life changed dramatically for the better. His marriage is really good now. He's a stable dad and he's working. He's down to only one or two meds.
You write about doctor dogs helping people with autism. Can you share an example?
Yeah, it's really beautiful. Sometimes these dogs may be using their nose. Sometimes they're just being highly observant. And dogs are. They watch our body language all the time. But there are now more dogs being used for children on the autism spectrum, and they are remarkable. They can usually tell ahead of time when a child is about to have a tremendous amount of anxiety, panic, meltdown or what have you. When there's too much stimulation for a child with autism and the dog is there, they'll lean into the child.
Dogs change lives not just of these children, but of the whole family.
There is a family I wrote about in Minnesota, with a sweet boy who waited for four years to get a service dog for his autism. He was not able to go to restaurants. The family, therefore, couldn't go to restaurants. He couldn't travel. He could barely leave the house. He did go to school, but that was tough, too. And so they waited four years. They tried to get a regular pet dog in the meantime, thinking, "Oh well, you know, it's a dog. It'll work." But it was a disaster. It did not work at all as a service dog.
So they got a service dog named Lloyd. He's a big black lab. As the boy met him, he started crying. His mother had never seen him cry. Tears of joy.
And right there, boom, everything changed. Lloyd is the super calming presence. He's able to be with the boy and change his behavior. The boy could not go to the barber and get a haircut before Lloyd. Now all he has to do is just have his hand on Lloyd's head.
And the boy and Lloyd like to have their own table at restaurants!

There Are Dogs ,Gay Whores and Leeches, Lindsay Graham is ALL of Those Except Gay Whores Keep To Their Words

He (Graham)is not talking about Trump here. Impeachment are for Dems only over lying over s e x

Just a few Tweets to go with the previous story:
South Carolina Senator Lindsey Graham, who was once a major Republican opponent of President Trump, has been supportive of more policies and moves in recent months. Graham's apparent switch has some Democrats and members of the media now putting out theories that Graham may have been blackmailed by Trump or the Russians.
Gee, whatever can you mean? Never mind, we know exactly what Stephanie Ruhle means. Does NBC? 
 The insinuation is referring to a long-time whispered rumor that Graham is secretly a homosexual and has been guarding it for many years.
MSNBC Anchor Stephanie Ruhle started things off earlier this week by making the vague speculation.
They got to him, he is compromised!
Things got a lot more heated when a member of Congress, Representative Ilhand Omar went after Graham on Twitter Wednesday night over the speculation. 

Conservative pundits say these speculations are essentially tone-deaf and hypocritical, with recent widespread media coverage of public personalities' past comments on homosexuality. They noted the lack of media coverage of the, "homophobic dog whistle" aimed at Senator Graham.
Other media personalities and Hollywood celebrities who have previously demanded repercussions towards those individuals joined the fray, making the same comments.

Hello. A few questions.

(1) Who is “they”?
(2) How did “they” “get to him”?
(3) How is he “compromised”?
(4) Is this a reference to the prominent & pernicious homophobic rumor that is circulating the internet? Because I might expect that from a troll, but you’re a Congresswoman.

Don't worry guys. @jaketapper will be sure to spend as much time on Omar as King. He's a straight-shooter, you see.

Does Your Dog Tilts His Head When You Talk to Him/Her?


I have fond memories of my Beagle, Darby, coming into the kitchen when I was preparing dinner. I would casually chat with him, and when I would turn to him to say something he would cock his head to the side in a most endearing manner. Many people report that when they are speaking to their dog their pet often tilts its head to the side, and some have asked me about why that happens.

Unfortunately, up to now, there is not been much research on this issue, although there has been some speculation. Some people have suggested that dogs tilt their heads to the side when we speak to them so that one ear can hear more clearly what we are saying. Others have suggested that it is a social signal—perhaps the dog recognizes that we respond to that particular posture in a positive way (because it is so cute) and therefore the dog adopts this position because they are more likely to get smiles and rewards when they do.

I suppose it is because I worked and did research in the area of sensory perception for many years that it dawned upon me that the reason some dogs tilt their heads when we are speaking to them has to do more with vision, rather than hearing and social endearment. Try the following simple experiment; hold your fist up to your nose as in the figure here. Now, in effect, you are viewing the world with a head shape that has a muzzle like that of a dog. If you now look at a person's face you will find that the muzzle will some of your vision, and reduce your ability to see the lower part of the face. Remember it is this part of the face, particularly the mouth region, which is a vital component of human emotional expressions. Next, still with your muzzle in place, tilt your head when you are looking at the face. With this head posture you can now clearly see the mouth region.
 We know that dogs continually scan our faces for information and to read our emotional state. Hence it is likely that one reason why dogs may tilt their heads when we talk to them is because they want to see our faces better, and to compensate for the way in which their muzzles obscure part of their vision.
Of course this idea was simply speculation, and no data were available. However it suddenly dawned upon me that there was an easy way to at least get a bit of data to confirm or disprove this hypothesis. Some dogs have flatter faces. Technically they are said to havebrachycephalic heads. These would include dogs like Pugs, Boston Terriers and Pekingese. With a less prominent muzzle extension, there should be a reduced amount of visual obstruction, and these dogs would need to tilt their head less. To see if this was the case I conducted a survey on the Internet.
The survey was very brief, and people simply had to answer how often their dog tilted their heads when they were speaking to them, using a scale which ran: never, seldom, occasionallyfrequently, most of the time, oralways. When I scored the data I combined the responses of frequently, most of the time, and always, an indication of "head tilting dogs". I also asked the people who responded to tell me for the breed of their dog, and for people with mixed breeds to select the approximate head shape of their dog from a set of six photos.
I got a very good response to this survey since 582 people completed it. Of these, 62% reported that their dogs frequently to always tilted their heads when they spoke to them. In the overall sample 186 people had dogs with the flatter brachycephalic heads. When we divide the group into those dogs with the more pronounced muzzles (technically those dogs with longer narrower heads like collies or greyhounds are doclichocephalic, while those with a wider intermediate length muzzles, like retrievers or beagles are called mesaticephalic) versus those with the flatter faces, we do get a difference in the frequency of head tilting. 71% of the owners of the dogs with the larger muzzles report that their dogs often tilt their heads when spoken to. On the other hand only 52% of the owners of the flatter faced, brachycephalic dogs reported that their dogs often tilted their heads when spoken to. This is a statistically significant difference that clearly suggests that head shape, and size of the muzzle does influence head tilting in dogs.
Now, of course, 52% of head tilting in the brachycephalic pets is still a large number of dogs, and it may be that even the flatter muzzles do obscure the dog's vision to some degree. If so, these dogs can still benefit visually from tilting their heads. However it is more likely that the fact that a dog's muzzle blocks their vision of the lower part of the human faces that they are trying to look at is just one of the factors that cause dogs to tilt their heads when we talk to them. Nonetheless this is a first step toward finding the answer, and at least we now have a bit of data to work with.
