Dr. Ruth Feldman, Ph.D., a social neuroscientist based in Israel, published a study of 112 mothers and fathers in 2010 which found that peaks in oxytocin (and by association, dopamine) occurred for women when they nurtured their children. In contrast, the peak for men occurred when they took part in rough-and-tumble play. Because young children’s brains seem to mimic the same oxytocin levels as their parents’ — meaning they’ll get a similar blast of feel-good oxytocin when playing with Dad and when being nurtured by Mom — they’ll be more likely to engage in that behavior over and over again specifically with that parent, which is critical to their development. Rough-and-tumble play not only cements bonds between father and child, but also plays crucial roles in a child’s social development.

So where does that leave us in terms of using it for cooking? In the end, it seems that the subgroup sensitive to MSG is small enough and the adverse reaction rare enough that in all likelihood you’re gonna be just fine using it in your own food, especially if you make sure to eat a little MSG-free stuff to lay down a bed in your belly before getting to the goods. Moreover all evidence suggests that the effects are at worst a short-term discomfort with no long-lasting consequences.
Complementary Medicine, Refusal of Conventional Cancer Therapy, and Survival Among Patients With Curable Cancers

Question What patient characteristics are associated with use of complementary medicine for cancer and what is the association of complementary medicine with treatment adherence and survival?
Findings In this cohort study of 1 901 815 patients, use of complementary medicine varied by several factors and was associated with refusal of conventional cancer treatment, and with a 2-fold greater risk of death compared with patients who had no complementary medicine use.
Meaning Patients who received complementary medicine were more likely to refuse other conventional cancer treatment, and had a higher risk of death than no complementary medicine; however, this survival difference could be mediated by adherence to all recommended conventional cancer therapies.
Evidence That Lifelong Low Dose Rates of Ionizing Radiation Increase Lifespan in Long- and Short-Lived Dogs
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5347275/, posted Jul '18 by peter in health science
After the 1956 radiation scare to stop weapons testing, studies focused on cancer induction by low-level radiation. Concern has shifted to protecting “radiation-sensitive individuals.” Since longevity is a measure of health impact, this analysis reexamined data to compare the effect of dose rate on the lifespans of short-lived (5% and 10% mortality) dogs and on the lifespans of dogs at 50% mortality. The data came from 2 large-scale studies. One exposed 10 groups to different γ dose rates; the other exposed 8 groups to different lung burdens of plutonium. Reexamination indicated that normalized lifespans increased more for short-lived dogs than for average dogs, when radiation was moderately above background. This was apparent by interpolating between the lifespans of nonirradiated dogs and exposed dogs. The optimum lifespan increase appeared at 50 mGy/y. The threshold for harm (decreased lifespan) was 700 mGy/y for 50% mortality dogs and 1100 mGy/y for short-lived dogs. For inhaled α-emitting particulates, longevity was remarkably increased for short-lived dogs below the threshold for harm. Short-lived dogs seem more radiosensitive than average dogs and they benefit more from low radiation. If dogs model humans, this evidence would support a change to radiation protection policy. Maintaining exposures “as low as reasonably achievable” (ALARA) appears questionable.

As data trickle in, entrenched camps have emerged. Some researchers are convinced that many patients have an immune reaction to gluten or another substance in wheat—a nebulous illness sometimes called nonceliac gluten sensitivity (NCGS).
Others believe most patients are actually reacting to an excess of poorly absorbed carbohydrates present in wheat and many other foods. Those carbohydrates—called FODMAPs, for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols—can cause bloating when they ferment in the gut. If FODMAPs are the primary culprit, thousands of people may be on gluten-free diets with the support of their doctors and dietitians but without good reason.
Those competing theories were on display in a session on wheat sensitivity at a celiac disease symposium held at Columbia in March. In back-to-back talks, Lundin made the case for FODMAPs, and Alaedini for an immune reaction. But in an irony that underscores how muddled the field has become, both researchers started their quests believing something completely different.

Researchers at Curtin University in Australia observed 20 participants working at standing desks for two hours.
They found discomfort “significantly” increased for the lower back and lower limb regions, which correlates with previous research suggesting standing desk is responsible for swelling of the veins, which can endanger the heart.
Mental reactiveness also slowed down after roughly an hour and a quarter, however “creative” decision making was shown to marginally improve.

Perhaps most startling, children between the ages of 15 and 19 are 82 times more likely to die from gun homicide in the United States than in peer countries.
America has 4.4 percent of the world’s population, but almost half of the civilian-owned guns around the world. Research shows that the more guns in a country, the more gun deaths. Conversely, states with fewer guns have fewer gun deaths.
In suburban sprawl, you’re doomed to spending vast amounts of time at the wheel–time you cannot do much else with, and which you won’t get back. The nature of low-density automobile sprawl cities is that everything is insanely far away from everything else, so no matter what you do, you’re doomed to driving vast distances to see most friends, to commute to work and so on.
The subjects cycled through high-gluten, low-gluten, and no-gluten (placebo) diets, without knowing which diet plan they were on at any given time. In the end, all of the treatment diets - even the placebo diet - caused pain, bloating, nausea, and gas to a similar degree. It didn’t matter if the diet contained gluten. (Read more about the study.)
"In contrast to our first study… we could find absolutely no specific response to gluten," Gibson wrote in the paper. A third, larger study published this month has confirmed the findings.
It should be noted that this study is not about celiac disease — what it's saying is that if you don't have that specific disease you can eat all the gluten you want.
The fly ash emitted by a power plant—a by-product from burning coal for electricity—carries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy.
