The Government has offered Australia's three mobile operators, and vividwireless, renewal of their existing spectrum allocated on 15 year licences in the late 90s and early 2000s at set prices, while the Government expects to rake in $3 billion.
Only 8% of the children from Polotitlán showed such brain lesions.
The Science News article “Bad air for growing brains and minds” (subscription may be required) states, “What’s more, brain scans of many Mexico City youngsters revealed alterations that can impair the prefrontal cortex, a neural region heavily involved in memory and thinking skills….”
The Calderón-Garcidueñas team concluded that dirty, polluted air could likely contribute to educational troubles in schoolchildren because these children also scored lower than healthy children when taking memory tests, performing problem-solving tests, and taking other such intellectual pursuits that are part of IQ (intelligence quotient) tests given to schoolchildren.
According to their abstract, “The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children."
Although their results are preliminary, they are following up this study with a more comprehensive study of a larger group of children over a longer period.
They also hope to break down the various pollutants in the air to determine which ones are causing brain problems and intellectual problems in children.
The Science News article concludes with: “In studies conducted since 2002, the researchers have reported signs of brain inflammation and brain disease in dogs exposed to Mexico City’s air."
And, "Earlier this year, the researchers found that chronic exposure to air pollution was associated with markers of brain inflammation and increased brain immune responses in children and young adults who had died suddenly and were studied at autopsy. These individuals also possessed high levels of brain proteins thought to contribute to Alzheimer’s and Parkinson’s diseases.”
