Welcome to the dark side

This is a NYT article about one of the reasons that Betsy DeVos shouldn't be confirmed as Secretary of Education. The article details a major conflict of interest in the performance of her duties. The DeVos' own a major share in a Biofeedback company called Neurocore which used Biofeedback to supposedly enhance children and teenager's performance in school. Although the company claims great success none of their results has been published in peer-reviewed journals.




https://www.nytimes.com/2017/01/19/well/live/for-better-vision-let-the-sunshine-in.html?_r=0  From the Well blog in the NYT magazine, an article reporting  that the rate of myopia (nearsightedness) has increased by 66% since the 1970s. This is a report in JAMA Opthalmology. A study was done at Kings College in London and other places, giving eye exams to older men and women and asking about their exposure to sunlight in childhood and adolescence (from memory). There is a correlation between exposure to sunlight in childhood and adolescence and incidence of myopia. There was also the implication that increased screen time may play a role.


https://mobile.nytimes.com/2017/01/21/opinion/sunday/does-breast-milk-have-a-sex-bias.html Article from the Sunday Review section of the NYT about whether breast fed girl and boy children get the same nourishment and how this relates to evolution. Work published in the Journal of  Experimental Child Psychology and done at Cal State Fullerton and the London School of Economics shows that they do not. When parents have beaucoup resources they devote them more to their sons but when resources are scare they devote them more to their daughters. The evolutionary explanation (the Trivers-Willard Hypothesis) is that males with access to more resources  are likely to gain access to more females to increase the likelihood that their genes will be passed on. Studies of lipid content of macaque and human mothers' milk was examined and compared based on the sex of the offsping recipient. And the research was continued on twins.


https://www.nytimes.com/2017/01/23/health/cervical-cancer-united-states-death-toll.html?_r=0 Article from the NYT aboutracial disparities that have been discovered in cervical cancer deaths . This study has been done at Texas' MD Anderson Hospital and published in the journal Gynecological Oncology. The alarming statistic of 10.1 deaths per 100,000 black women compared to 4.7 white women per 100,000 is a change from 5.7 to 3.2 in previous studies.
