Farmers are stuck in a chemical war against weeds, which have developed resistance to many widely used herbicides. Seed companies’ answer – using more varied herbicides – is causing new problems.
Scientist Michelle Murphy says we should ‘value wastelands …and injured life.’ Here, collected plastic from the shoreline of Hamilton, Ontario is sorted by colour.
In this episode, two Indigenous scientists running collaborative labs to address our climate crisis offer some ideas for environmental justice, including a redefinition of pollution.

We can fine-tune bacteria using algorithms to help them produce the things we need, from antibiotics to methane.
Paraquat’s potentially lethal effects on humans are well known. But our research has found it also causes serious environmental damage.
Phthalates can be found in many common products and types of plastic packaging.

Two environmental engineers say governments need to do more to protect people from possible water contamination after wildfires.
The same chronic illnesses associated with exposure to endocrine-disrupting compounds also increase risk of developing severe COVID-19.

Endocrine-disrupting compounds are pervasive in modern life, from food packaging to shampoo. Research is connecting their effects on humans to risk of severe illness or death from the coronavirus.

A storm-driven chlorine gas release in a vulnerable community is the type of worst-case scenario that scientists and engineers have warned about for decades.
For combustion to occur, oxygen must be present. Ammonium nitrate prills provide a much more concentrated supply of oxygen than the air around us.
The 2018 Camp Fire north of Sacramento burned everything in its path: cars, power lines, and buildings – and contaminated local drinking water.

Buildings aren’t the only things at risk in wildfires. Recent disasters in California have left local water system contaminated with toxic chemicals afterward, slowing return and recovery.
Pepper spray uses a chemical called capsaicin. It’s the same compound that makes chillies hot, but in a more intense, weaponised form.
Phosphorus was first discovered by boiling down thousands of litres of urine.
We need phosphorus for life, as well as for fertiliser to help plants grow, but raw supplies are limited.
The chemicals in nail products put nail salon workers at risk for cancer and other illnesses.
The technician who gave you that shiny manicure may be inhaling dangerous levels of toxic chemicals on the job.
One slice is never enough.
Pizza might seem like a simple food, but it’s uniquely equipped to excite our brains and thrill our taste buds.
A battery’s power comes from a chemical reaction that happens inside the cell.
Firefighting foam containing PFAS can get into waterways. But the evidence doesn’t give us reason to worry about our health.
Episodes of reported PFAS contamination are never far from the news. Here’s a run-down of what PFAS is, and why we have little reason to worry about its potential effects on our health.
‘Larry, I have to confess. I’m not a wasp. I’m an orchid.’
You can barely communicate with your kids, but these creatures are sending complex interspecies instructions.
