    Is Everything Getting Fatter?

    Here’s a weird and interesting paper to think about. There’s an unfortunately clear trend in human populations towards obesity, which seems to have been especially noticeable over the last thirty years or so. (I believe that the average-thinnest US state today would have been the fattest state in 1980, just to give one vivid example).… Read More

    Organ Models on Chips

    Why do we test new drug candidates on animals? The simple answer is that there’s nothing else like an animal. There are clearly chemical and biological features of living systems that we don’t yet understand, or even realize exist – the discovery of things like siRNAs is enough proof of that. So you’re not going… Read More

    Whatever Happened to the Fish and the Frogs?

    Eight or ten years ago, there was a good deal of excitement about non-mammalian small animal model systems for compound screening – specifically fish and frogs. More specifically, zebrafish and Xenopus. A number of small companies started up to do this sort of thing, and large companies paid attention as well. A correspondent, though, wrote… Read More

    Near-Animal, Near-Human: The Future of Drug Testing?

    Here’s a good article on animal models in drug discovery, and their many limitations. We have moved away from studying human disease in humans,” (Elias) Zerhouni lamented to the NIH’s Scientific Review Management Board meeting. “We all drank the Kool-Aid on that one, me included.” “The problem is that it hasn’t worked, and it’s… Read More

    Mouse Models of Inflammation: Wrong Or Not?

    I wrote here about a study that suggested that mice are a poor model for human inflammation. That paper created quite a splash – many research groups had experienced problems in this area, and this work seemed to offer a compelling reason for why that should happen. Well, let the arguing commence, because now there’s… Read More

    Animal Testing in the UK.

    A reader sends along news that a minister at the UK’s Home Office has made it his goal to completely eliminate animal testing in the country. Norman Baker has been a longtime activist on the issue of animal rights, and is now in a position to do something about it. Or is he? Reading the… Read More

    Mice Hate Men

    The difficulty of doing good animal studies has come up here many times, such as the recent suggestion that many rodent facilities should adjust their thermostats. Now comes word of yet another subtle effect that no one has ever controlled for: mice apparently react different to the scent of human males as compared to human… Read More

    A Call For Better Mouse Studies

    Here’s an article by Steve Perrin, at the ALS Therapy Development Institute, and you can tell that he’s a pretty frustrated guy. With good reason. That chart shows why. Those are attempted replicates of putative ALS drugs, and you can see that there’s a bit of a discrepancy here and there. One problem is poorly… Read More

    Lab Mice Are Being Kept Too Cold, Apparently

    Earlier, the unsuitability of mice in inflammation models was shown in a paper that should have been noted by anyone in the field. Just last month, a paper in Science detailed the problems with many animal studies (mouse and otherwise), particularly the smaller ones, which can suffer from bad statistics and poor protocols. Now we… Read More

    Of Mice (Studies) and Men

    Here’s an article from Science on the problems with mouse models of disease. or years, researchers, pharmaceutical companies, drug regulators, and even the general public have lamented how rarely therapies that cure animals do much of anything for humans. Much attention has focused on whether mice with different diseases accurately reflect wh… Read More
