NEUROTOXIC Triclosan Was Pushed in my Kids' Elementary School

I recall when my son's class would be lined up before snack and lunch with the teacher spraying "hand sanitizer" with triclosan on their hands. The kids did not rinse their hands before eating.

At the time I was suspicious so I insisted that my son wash his hands with soap and water. The teacher and her assistant thought I was crazy but now years later my concerns are vindicated with research showing that triclosan is neurotoxic, particularly during pregnancy but who knows what long term effects  accrue for kids with chronic exposure:
Medina S. Jackson-Browne, George D. Papandonatos, Aimin Chen, Antonia M. Calafat, Kimberly Yolton, Bruce P. Lanphear, and Joseph M. Braun Identifying Vulnerable Periods of Neurotoxicity to Triclosan Exposure in Children Published 2 May 2018 | Research 
Exposure to triclosan, an endocrine disrupting chemical, may affect thyroid hormone homeostasis and adversely affect neurodevelopment. 
Using a longitudinal pregnancy and birth cohort, we investigated associations between triclosan exposures during different time windows, and cognitive test scores at 8 y of age in 198 children from the HOME Study 
We quantified triclosan in urine samples from mother–child pairs up to nine times between the second trimester of gestation and 8 y of age. The Wechsler Intelligence Scale for Children-IV [i.e., Full-Scale Intelligence Quotient (IQ)] assessment was administered to HOME Study children at 8 y of age. We estimated covariate-adjusted triclosan–IQ associations at each visit. We also tested whether associations between triclosan concentrations and cognitive test scores varied among exposure at different time periods. 
Full-Scale IQ was not significantly associated with urinary triclosan concentrations during gestation or childhood but was significantly associated with a 10-fold increase in maternal urinary triclosan concentration at delivery [−4.5 points (95% CI: −7.0, −2.0)]. Perceptual Reasoning Index (PRI) scores were significantly decreased in association with urinary triclosan concentrations at delivery and at 2 y of age. Associations between repeated triclosan concentrations and cognitive test scores significantly varied among exposure at different time periods for Full-Scale IQ, PRI, Verbal Comprehension Index, and Working Memory (triclosan–visit interaction p≤0.04). 
Urinary triclosan concentrations at delivery, but not during mid to late pregnancy and childhood, were associated with significantly lower children’s cognitive test scores at 8 y of age in this cohort of U.S. children.
Once again, the public was duped by a reckless chemical industry.

Fukushima Daiichi Unit 2 Really Steaming in Rain

TEPCO has told us that unit 2 is the hottest. You can really see that when it rains. Unit 2 is the one with the steam streaming upwards (Unit 3 in the background also looks especially steamy):

These reactors are still a threat because of liquefaction at the site coupled with earthquake activity.

The fuel is extraordinarily hot. I hope TEPCO is successful in its efforts to prevent any of these buildings from collapsing.
