  1. Re:High fat? on High-Fat, High-Sugar Diet Can Lead To Cognitive Decline · · Score: 1

    He mostly just said that are mice are designed to run on a grain based diet. The study is clearly motivated by the natural diet of a particular organism. From the intro: "The Western diet contributes to many chronic, diet-related illnesses in the United States, including the obesity epidemic (Cordain et al., 2005). Western diets are typically high in fat and simple carbohydrates (CHOs) (Cordain et al., 2005). Higher intake of fats and refined sugars are associated with deficits in cognitive flexibility and hippocampal-dependent memory in humans (Kalmijn, 2000 and Francis and Stevenson, 2011) and an increase in the incidence of Alzheimer’s disease (Pasinetti, 2002)." When that diet is altered, things will change, including gut bacteria. Will there be other important changes? The study doesn't address that, but the sensible working hypothesis should be: yes, radical dietary changes affect more than gut bacteria. Let's look at the end of the discussion to see if this makes a difference: " Interestingly, mice fed 33% fat, in the form of lean ground beef, showed better long- and short-term memory than those on 12% fat (Li et al., 2009)." Maybe all the stuff in the diet besides the current macronutrients of interest actually matter??

  2. Another lousy study with an agenda on High-Fat, High-Sugar Diet Can Lead To Cognitive Decline · · Score: 1

    If you're going to study high fat vs high carb, you'd at least control for protein and calories, right? NO!!!!!! THE HIGH FAT DIET HAS LESS PROTEIN AND MORE CALORIES!!!!! Previous studies in this field have also been misleading: "It’s well known that in mice, “high-fat diets” induce endotoxemia. But these diets aren’t necessarily high in fat – any pelleted rodent food in which fat provides more than 20% of calories may be called “high-fat.” The critical difference of “high-fat diets” from chow is that they are composed of purified nutrients – starch, sugar, oil, vitamins, and minerals – whereas chow is composed of natural whole foods such as wheat, corn, and seeds." (http://perfecthealthdiet.com/2015/06/disease-begins-in-the-mucus/) At least they didn't use a "high fat high cholesterol" diet with ridiculous amounts of purified cholesterol.

  6. Re:Way too many humanities majors on Why America's Obsession With STEM Education Is Dangerous · · Score: 1

    If an engineer doesn’t know why he should be building something, then that something should be avoided. If he can’t explain why he designed a bridge in a particular way, then stay off the bridge! If his boss can’t explain why a bridge would improve traffic patterns, in some quantitative way, then it shouldn’t be built either. When these conditions are violated, it’s usually for the benefit of someone besides the engineers. A well trained engineer would not build a bridge to nowhere, or allow an unsafe shuttle to fly. These decisions are made by people who answer to social and personal pressures but not science or engineering principles. Part of the problem is greed, but another part is ignorance. Both will be big problems with AI, and studying humanities will not allow anyone to intelligently decide whether a particular machine resembling AI should or should not be built. They have no standing under which to make an argument. You can’t simply expect them to spew out some philosophy and convince a legal body that they understand the consequences of the machine better than those who designed it, and can quantify its purpose and abilities. You can’t effectively regulate what you don’t understand, and you won’t understand anything resembling AI in any meaningful way without some technical background. The precautionary principle is your only regulatory hope, and realistically that isn’t going to prevent AI malfeasance. Since we don’t know what this AI will look like, the answers to which technoligies should be suppressed must be picked up as its designers and observers go along. A solid background in science can’t just be picked up as you go along, if you’ve ignored it your whole life. But with a good background in some scientific area, other scientific expertise can be readily picked up along the way. I have no background in chemistry but now I work in a lab where biochemistry is a main focus. I’m picking it up to research level, but that would not be possible with a pure education in humanities. And the implications of any technoligy I may create? How could I expect someone to understand those implications without understanding the technology?

    If critical thinking involves "knowing" when to apply equations, then critical thinkers must have experience applying equations. That comes from STEM education and not humanities. Understanding people and their motivations is surely important for selling stuff, and many other things. Fortunately there are (arguably) sciences that deal with these subjects directly - psychology and sociology.

Also there is stigma involved - some people have a very negative view of crossfit, and hate paleo by association. Some people just think that only an idiot would remove entire classes of food from their diet. Vegans avoid paleo because it involves eating animals or animal products.

    Still, Hell no. It's fairly new and expensive, so every lab in the world is not going to have one. But it's commonplace enough that if it's used to support a result, it's not necessarily even advertised in the abstract. These results are cited by other labs as inspiration and support for their work, which in my view counts as usage. Moreover, its usage and acceptance has grown much faster than, say, the confocal microscope.

  18. So misguided on Bioethicist At National Institutes of Health: "Why I Hope To Die At 75" · · Score: 1

    He seems to be arguing that diet and exercise do not improve quality of life before 75. I have news for this arrogant egghead who is obviously spoiled by his own good health: many of us NEED to focus on these things to maintain a decent quality of life before 75. It's not some silly obsession to cheat death. We must do this precisely because the modern sick-care system sustains the cushy status of bioethics "experts" who do very little to rein in the food and pharmaceutical companies who are responsible for the proliferation of widespread, chronic diseases such as diabetes, especially among the poor. This system fails those of use who are cannot adapt to some part of the modern industrial food and chemical complex. We're on our own, there are a lot of us, and obsessing about these things has been the only way we've been able to get our health on track. So instead of belittling the health-conscious, how about calling out public schools and TV advertisers that flood kids' minds and bodies with processed junk snacks? How is this different than passing out crack?? Why would anyone believe that poor diet and lack of exercise will have no effect until age 75, aside from an egocentric lack of personal experience?

    Asperger's was not exactly eliminated from the DSM-V. Its diagnosis criteria were simply lumped into the category of Autism Spectrum Disorder. Many functional slashdotters would be diagnosed with this disease, and perhaps even medicated. How do you know that over-medicating kids isn't the main driver behind actions like these? Sure, psychiatrists are trying to help, but the fact that they're just beginning to explore a difficult new field should scream "HEY, they don't understand the systems they're pharmacologically manipulating, and their actions are quite possible doing kids and society lots of harm!" This is not how science works. It's how fishing works. They didn't catch a fish with their Asperger's lure, so they made up another ad hoc classification which will surely be changed again, probably to be treated with a different cocktail of drugs whose actions are minimally understood, but provide plenty of profit for pharmaceutical companies.

    My impression is that it's mostly about things like tariffs and pollution. If one government subsidizes the production of widgets (via cash or lack of regulation), then companies in that country can afford pay the same wages and make more profit than companies in another country. For the subsidizing government's lawmakers, this is a win because their economy gains a global competitive advantage, and employment is increased in that country. In response, the disadvantaged country can impose tariffs and restrictions. These economic and political barriers go hand in hand with international disparities in labor costs, oil consumption per capita, real estate costs, etc.
