Adventures in bad veterinary medicine reported by the local media, year end edition [Respectful Insolence]


Ever since moving back to the Detroit area nearly seven years ago, one thing I’ve noticed is a propensity for our local news outlets to go full pseudoscience from time to time. I’m not sure why, other than perhaps that it attracts eyeballs to the screen, but, in reality, most of these plunges into pseudoscience and quackery are so poorly done that I find it hard to believe that even believers find them interesting. For example, back in 2008, I discussed a particularly dumb story aired by our local NBC affiliate WDIV entitled Orbs: Myth or Real?, which, not having started my new job yet, I gleefully deconstructed at the time. For those of you who aren’t familiar with “spirit orbs,” which are claimed to be the spirits of the dead but almost always represent photography artifacts, such as lens flare, dust on the lens catching light, or similar things that can lead to light blobs showing up on photos.


Also at the time, an investigative reporter named Steve Wilson was still spreading antivaccine mercury militia pseudoscience through the local ABC affiliate WXYZ, leading me to wonder whether he was a a legitimate investigative reporter or an antivaccine propagandist. Indeed, his antivaccine propaganda dressed up as news reports was spreading to a national audience, thanks to Age of Autism and other antivaccine groups. Actually, he was both. When it came to politics and corruption, he was a decent investigative reporter; indeed, his exposes of our utterly corrupt former mayor Kwame Kilpatrick’s were, in retrospect, prescient, and provoked Kilpatrick to take his revenge. When it came to vaccines, he had completely swallowed the Kool Aid that claims that mercury in vaccines caused an autism epidemic. I’m not sure if it was the antivaccine reporting or other issues, but Wilson’s contract was, fortunately, not renewed in in 2010.



In any case, given the record of local news stations when it comes to credulously reporting medical pseudoscience (and pseudoscience in general), I would normally not be surprised to see a report on a local station in which quackery is presented as real medicine. (Heck, I deconstructed just such a story a year and a half ago.) I was more surprised (but probably shouldn’t have been) to see such a report in our local newspaper, the Detroit Free Press complete with a video for the online story. The story is by Jennifer Dixon and is entitled Veterinarian offers alternative approach to healing. The story is even showing up in statewide media. Ms. Dixon is an investigative reporter, but in this case hers was a massive fail to do even the most basic investigation, so much so that one wonders if we have another Steve Wilson in the making.


Basically, it’s so credulous that it might as well be an advertisement for a veterinarian named Dr. Loren Weaver, who subjects animals to a variety of nonsensical treatments:











The video is painful to watch, so steeped in mystical woo is it. It’s hard to believe that this sort of rot made it even on the air even from a local news station, but it did. The text begins:



Dr. Loren Weaver practices “energy medicine” on dogs, horses and the occasional cat.


“There’s a big transfer of energy from me to the dogs, from the dogs to me, me to the horses and the horses back to me. That’s what makes this work is that transfer of energy,” the veterinarian said. “That’s what I pass through with my hands.”


He said that energy, or Chi, is carried through 12 meridians, or channels, in the body.


“I don’t ask someone to believe it exists,” he said. “If you let me work on your animal, I can show you how it works.”


His patients’ owners are believers.



Let’s get one thing straight right here, right now. “Energy medicine” is quackery. It’s mystical mumbo-jumbo with no basis in science. Reiki, for instance, the most common form of “energy medicine” is basically faith healing in which Eastern mystical beliefs replace Christian beliefs as the religious basis for belief that laying on hands can heal. It’s “The Secret“-level wishful thinking, and, unfortunately, reiki for Fido is becoming more common.


Of course, what Weaver describes as his “energy medicine” doesn’t sound like reiki. He doesn’t invoke the “universal source” as the source of the healing energy but rather seems to be claiming that he can manipulate animals’ “energy fields.” That sounds a lot more like “healing touch” (HT) or “therapeutic touch” (TT) another pseudoscientific mystical modality that is, unfortunately, all too commonly practiced in hospitals and is equally ridiculous as reiki. I like to say that it’s so ridiculous that even an 11-year-old girl could design a controlled study that demonstrated that TT practitioners cannot even sense a human “energy field,” much less manipulate one. This is not surprising, given that what TT practitioners mean by “energy” and what scientists mean by “energy” (to put it simply, the capacity of a physical system to perform work) are not even related by coincidence. Even with the most sophisticated and sensitive instruments, science has never been able to find anything like these “energy fields” around humans or animals that can be manipulated in the way that people like Dr. Weaver claim. Basically, energy medicine is prescientific vitalism infused with a heavy dose of religion. That is why I consider it quackery.


In any case, it turns out that Dr. Weaver is a veterinarian and a chiropractor. As I and others have pointed out before, basically any form of alternative medicine to which humans are subjected is also used in animals because, well, I guess we humans can’t help ourselves. We have to subject our furry, feathered, and scaly friends to the same sort of prescientific and pseudoscientific nonsense that we subject ourselves to. Hence, we see travesties, such as turtles and owls getting needles stuck into them and ducks and Basset hounds having their spines adjusted. Not surprisingly, Dr. Weaver is heavily into both chiropractic (being a chiropractic veterinarian) and acupuncture, both of which are on full display in this story.


Weaver even goes full Palmer on us and talks about the “innate intelligence” (although he doesn’t call it that) flowing from the brain through the nervous system and how anything impeding that flow will cause problems. Meanwhile, we are treated to images of Weaver doing spine adjustments on dogs, who most definitely do not appear to be enjoying it, as at least one of them has to be held and jerks as if in pain when Weaver does a lower spinal adjustment. One dog, a Dachsund named Rocky, is shown trying to bite Weaver as he adjusts his spine, all while his owner exults about how fantastic Rocky is doing for his slipped disc ever since Dr. Weaver started treating him. Of course, in the case of actual pathology, such as a disc problem, it is possible that spinal manipulation might be of some benefit, or, as is the case in humans, the course could be resolution in many cases. After all, from what I’ve observed we apear not to operate on herniated discs nearly as often as we used to.


Later in the video, Weaver is shown sticking needles into dogs, most of whom most definitely appear not to be liking it at all, as they all flinched as the needles were placed and had to be held to keep from biting at them. Meanwhile, he pontificates on traditional Chinese medicine (TCM) and how TCM teaches that disease is due to “blockages” of qi that can be resolved using acupuncture. Doesn’t Weaver know that TCM is a retconning of the actual history of Chinese folk medicine perpetrated by Chairman Mao Zedong back in the 1950s? Apparently not:



Weaver has been a veterinarian for 34 years and has been practicing acupuncture and chiropractic medicine for the last 26 years. He was first exposed to acupuncture while living in Kenya and saw how it helped horses in pain.


“It worked, and the horses relaxed and felt better,” Weaver said. When he returned to the U.S., he began studying acupuncture, which he uses for pain relief and back problems. He then immersed himself in chiropractic medicine. The son of a farmer who saw a chiropractor for his back, Weaver said he was exposed to chiropractic medicine as a child.


“When I started, no one was doing chiropractic,” Weaver said.



How does he know it helped? Proponents of alternative medicine will claim that quackery like acupuncture “works” in animals because it couldn’t possibly be due to placebo effects, but they are only sort of correct. The reason is that the only way we can know what animals are feeling is through the observations of humans, who interpret those observations as the animal either being in pain or getting better. Thus, placebo-like effects can occur in animals, but in reality they are a result of a change in perception of the animal’s condition by the owners, who expect results and, after treatment, look for results. If they believe acupuncture will work, often they report results. It’s difficult enough to quantify pain reliably in humans; in animals, it’s even harder. Add to that the tendency of most conditions to regress to the mean or to slowly improve, and, if the acupuncture or chiropractic adjustment is performed as improvement is beginning or around the time when the symptoms are at their worst (which is often the time when treatment will be sought), then it can appear that the treatment “worked.” There appears to be a phenomenon in veterinary medicine known as caregiver placebo effects, which appears to be a real phenomenon. Indeed, frequently, there is little or no correlation between owner-reported observations of animal pain and objective measures.


All of this explains why Dr. Weaver can have so many glowing testimonials about the efficacy of his methods, some of which are presented in this story. Unfortunately, our intrepid “investigative reporter” didn’t actually investigate. Instead, she produced an advertisement for Dr. Weaver, chiropractic veterinary medicine, and the use of TCM in animals. I realize that local reporters are often assigned human interest stories like this. People love their pets, and the story of an appealing, warm and cuddly vet who seems to be “working miracles” is a very tempting story to do. Everybody loves a story like this, particularly animal lovers, except, of course, “nasty” buzzkill skeptics like myself who, upon seeing a story like this, can’t help but look deeper.

New video shows life in the deepest ocean



The deepest part of the ocean is in the Mariana Trench (sometimes called the Marianas Trench), located in the western Pacific Ocean. At its deepest part, it’s just under 7 miles (6.831 miles / 10.994 km / 10,994 meters) deep. Using the UK’s deepest diving vehicle – the Hadal-Lander – an international team of marine biologists, geologists, microbiologists and geneticists recently probed this area, captured video of the world’s deepest ocean life, discovered some new species and set a new record for the world’s deepest known fish.


Just before Christmas (December 19, 2014), the University of Aberdeen released information and the video above, based on these scientists’ recent 30-day journey to this cavernous part of the ocean floor.


Mysterious supergiant amphipod, filmed alive for the first time. This extremely large crustacean was first recovered by traps off New Zealand in 2012.

Deepest known fish is now a snailfish, the fragile creature to the left of center in this image, at a depth of 8,145 meters in the Mariana Trench.



Among other things, they captured the first footage of a live and very mysterious supergiant amphipod. This creature, an extremely large crustacean, was first recovered by traps off New Zealand in 2012. The new footage shows the supergiants swimming, feeding and fending off would-be predators with its large body size and protective tail. Alan Jamieson from the University of Aberdeen was part of the expedition. He said:



Knowing these creatures exist is one thing, but to watch them alive in their natural habitat and interacting with other species is truly amazing.



The video footage also shows a type of snailfish at depths of 8,145 meters – 500 meters further down than the greatest depth that fish had been observed prior to this expedition. Jamison said:



This really deep fish did not look like anything we had seen before, nor does it look like anything we know of. It is unbelievably fragile, with large wing-like fins and a head resembling a cartoon dog.



In all, the scientists completed 92 deployments of deep-sampling equipment across the entire depth range of the trench (5000 meters to 10,600 meters deep). That’s the greatest number deployed to the Mariana Trench so far, they say.


The scientists and their diving vehicle traveled aboard Schmidt Ocean Institute’s Research Vessel Falkor.

2014 Castle Excavation Reports [Aardvarchaeology]

Things are coming together with the post-excavation work for last summer’s castle investigations so I’m putting some stuff on-line here.



  • I’ve submitted a paper detailing the main results to a proceedings volume for the Castella Maris Baltici symposium in Lodz back in May. There are no illustrations in the file, but you’ll find all you need here on the blog in various entries tagged ”Castles”.

  • Osteologist Rudolf Gustavsson has completed his reports on the bones from the two sites (LandsjöStensö).


For the Dear Reader who doesn’t read Swedish, a short summary of Rudolf’s results is in order. As expected, there are no human bones: this is food waste. The material from both sites is dominated by youngish pigs followed by sheep/goat and cattle in roughly equal fragment numbers. Pig parts represented at Landsjö suggest slaughter on site. Chicken was also eaten at both sites. Both sites have fish species that would have been available in the body of water overlooked by the castle. Landsjö’s trench D has large parts of a fox whose femur shows a healed break. It’s from the top layer that probably represents post-Medieval, post-castle slope erosion, and thus doesn’t seem to have anything to do with courtly hunting.


Questions and comments on the documents are most appreciated!

Find the bright Dog Stars on December evenings


Tonight, look for the two Dog Stars. The brighter of the two is Sirius, which makes up the neck of the constellation Canis Major, the Greater Dog. Sirius is easy to spot, because it also happens to be the brightest of all the stars we see in our night sky. The other Dog Star is Procyon in the constellation Canis Minor the Lesser Dog. Procyon means “before the Dog” because this star’s rising signals that Sirius, the Dog star, is soon to follow Procyon into the sky.


There’s a comet in the sky now that you can see with binoculars. In fact, if the moon weren’t so bright now, you might be able to see this comet with your eye, under exceptionally good sky conditions. Doesn’t matter. Dust off the binoculars and try to see Comet Lovejoy! At the moment, it’s not far in the sky from the stars Sirius and Procyon. Click here to see photos and get more info about Comet Lovejoy.

Also bright in the sky, although less so than Sirius, is the star Adhara, which makes up the Larger Dog’s bottom right foot. Although it’s true that Sirius has the brightest apparent magnitude of all the visible stars, Adhara actually has a brighter absolute magnitude than Sirius. In other words, Sirius looks bright to us because it’s closer. But if the two stars were observed at an equal distance from Earth, Adhara would appear brighter than Sirius.


Apparent magnitude is the measure of brightness of a star as seen from Earth at the star’s natural distance. Absolute magnitude is the measure of the brightness of a star as seen from Earth if the star were placed at a distance of 32.6 light-years from the Earth. So, while Sirius may be the brighter star, this is not because it is intrinsically more luminous. It is because Sirius is much closer to the Earth than Adhara.

Bottom line: If you’re in the Northern Hemisphere, and you look towards the southeast tonight in late evening, you’ll find Sirius, the brightest star in the sky. Sirius is also the brighter of the two Dog Stars. It is said to represent the neck of the constellation Canis Major, the Greater Dog. The other Dog Star is nearby Procyon, in the constellation Canis Minor the Lesser Dog. Also in this part of the sky … Comet Lovejoy. Click here to find out more about the comet.

Rising times of Procyon and Sirius into your sky

Tonight, look for the two Dog Stars. The brighter of the two is Sirius, which makes up the neck of the constellation Canis Major, the Greater Dog. Sirius is easy to spot, because it also happens to be the brightest of all the stars we see in our night sky. The other Dog Star is Procyon in the constellation Canis Minor the Lesser Dog. Procyon means “before the Dog” because this star’s rising signals that Sirius, the Dog star, is soon to follow Procyon into the sky.


There’s a comet in the sky now that you can see with binoculars. In fact, if the moon weren’t so bright now, you might be able to see this comet with your eye, under exceptionally good sky conditions. Doesn’t matter. Dust off the binoculars and try to see Comet Lovejoy! At the moment, it’s not far in the sky from the stars Sirius and Procyon. Click here to see photos and get more info about Comet Lovejoy.

Also bright in the sky, although less so than Sirius, is the star Adhara, which makes up the Larger Dog’s bottom right foot. Although it’s true that Sirius has the brightest apparent magnitude of all the visible stars, Adhara actually has a brighter absolute magnitude than Sirius. In other words, Sirius looks bright to us because it’s closer. But if the two stars were observed at an equal distance from Earth, Adhara would appear brighter than Sirius.


Apparent magnitude is the measure of brightness of a star as seen from Earth at the star’s natural distance. Absolute magnitude is the measure of the brightness of a star as seen from Earth if the star were placed at a distance of 32.6 light-years from the Earth. So, while Sirius may be the brighter star, this is not because it is intrinsically more luminous. It is because Sirius is much closer to the Earth than Adhara.

Bottom line: If you’re in the Northern Hemisphere, and you look towards the southeast tonight in late evening, you’ll find Sirius, the brightest star in the sky. Sirius is also the brighter of the two Dog Stars. It is said to represent the neck of the constellation Canis Major, the Greater Dog. The other Dog Star is nearby Procyon, in the constellation Canis Minor the Lesser Dog. Also in this part of the sky … Comet Lovejoy. Click here to find out more about the comet.

Read the message your dog sends with his tail



Tail-wagging in dogs is the classic signal for happiness. But researchers have found that tail-wagging can mean that your dog is either happy or stressed.


Activation of the left-brain causes a dog’s tail to wag to the right. Activation of the right-brain causes a wag to the left. That’s not new knowledge. Scientists detected that difference seven years ago.


What is new is that, not surprisingly, other dogs can easily read the message your dog is sending with his tail. And so can you.


Researchers at the University of Trento in Italy tested 43 dogs of various breeds for their ability to distinguish between tail wags. They showed the dogs videos of other dogs wagging their tails (much like the one above) and monitored the dogs’ heart rates and reactions. How could they be sure that the dogs weren’t watching their canine buddies’ facial or body cues? The researchers also showed the dogs only a silhouetted version of a tail-wagging dog.


As it turned out, every dog responded the same way. Dogs watching other dogs wag their tails to the left looked anxious, and their heart rates increased. In other words, they, too, became stressed. But dogs watching others swing their tails to the right stayed calm and relaxed — an indication that right wags are an expression of companionship and confidence, according to these scientists.


Why study tail wags in dogs? The team said in the summary to their study, which was published in Current Biology last year:



The finding that dogs are sensitive to the asymmetric tail expressions of other dogs supports the hypothesis of a link between brain asymmetry and social behavior and may prove useful to canine animal welfare theory and practice.



Bottom line: A dog wagging his tail to the right is happy, but a dog wagging to the left is stressed, say researchers.
