Drawing a tube of blood could assess ALS risk from environmental toxin exposure

Researchers developed an environmental risk score to assess ALS risk and survival using a blood sample, associating several individual pollutants with disease risk. A mixture of pesticides in the blood significantly increased ALS risk, with those in the highest group having twice the risk as those in the lowest.

Newly discovered fungus helps destroy a harmful food toxin

A newly discovered fungus has been found to transform the toxic compound patulin into less harmful byproducts, offering potential solutions for controlling its presence in food products. The fungus, identified as Acremonium sp., was shown to degrade patulin into desoxypatulinic acid and other compounds, which are significantly less toxic.

Researchers identify 10 pesticides toxic to neurons involved in Parkinson’s

Researchers at UCLA and Harvard have identified 10 pesticides toxic to dopaminergic neurons, which play a key role in voluntary movement. The study used California's pesticide use database and found that co-exposure of certain pesticides increased toxicity, with combinations involving herbicides like trifluralin producing the most harm.

Study reveals how pollinators cope with plant toxins

A study by the University of Exeter and Bayer AG found that pollinators produce a conserved family of cytochrome P450 enzymes to tackle alkaloid toxins in plants. These enzymes allow bees to safely consume nectar and pollen from toxic plants, shedding light on insect tolerance mechanisms.
