Plasticizers are a general term for a whole range of chemicals added to materials, typically plastic and rubber, to make them softer and more pliable. They're found in countless everyday items like plastic shower curtains, shrink-wrap, PVC raincoats or flexible tubing and wire insulation for homes. Plasticizers, sometimes called phthalates, are also found in cosmetics, like nail polishes, lotions and shampoos.
Exposure to a fungicide induced changes to gene expression in rats that persisted for at least 20 generations. It also increased the chance of offspring developing kidney disease, obesity or experiencing complications when giving birth, according to the longest-running study of 'epigenetic' changes in mammals.
"The loss of a student is heartbreaking and our thoughts are with Kasie's family, friends, classmates, faculty, and all who knew and cared for him," the letter reads. "We recognize that news like this can be very distressing and may bring up many emotions. Please know that you are not alone and support is available."
A potent neurotoxin capable of causing lifelong damage to the lungs, brain, skin and other organs, mercury is strictly regulated worldwide. Children, in particular, can suffer severe developmental impairment when exposed. A trace element that occurs naturally in rocks such as limestone, as well as in coal and crude oil, mercury remains locked underground for millions of years, largely entering the ecological cycle through human activity.
Donald Trump's EPA has said that easing the pollution standards for coal plants would alleviate costs for utilities that run older coal plants at a time when demand for power is soaring amid the expansion of datacenters used for artificial intelligence. But environmental groups have said that weakening standards for mercury, a neurotoxin that can impair babies' brain development, and other air toxics will lead to higher health-related costs.
Our study suggests that living near a [nuclear power plant] may carry a measurable cancer risk - one that lessens with distance. We recommend that more studies be done that address the issue of NPPs and health impacts, particularly at a time when nuclear power is being promoted as a clean solution to climate change.
The state health department reports that, between late November 2025 and early February 2026, there have been four deaths and 40 hospitalizations linked to consumption of dangerous mushrooms, an outbreak the department describes as unprecedented. That's far above the average for the state, which typically sees fewer than five mushroom-poisoning cases annually. The people who have been sickened include a seasonal farm worker couple from Oaxaca, Mexico.
Many human activities - from improper disposal of waste to the degradation of car tyres - release small plastic particles, which have infiltrated the atmosphere, oceans and other ecosystems. These include nanoplastics - particles measuring less than 1 micrometre across - and microplastics, which range from 1 micrometre to around 5 millimetres. They've entered our bodies and brains, and scientists are still working to understand their effects on people's health.
