Environmental Protection Agency asked firm to choose rules it wanted for dicamba, then put the choices in a proposed federal rule

The EPA allowed pesticide giant Bayer to pick from a menu of regulation options for the controversial and destructive weedkiller dicamba, newly released internal agency documents show.

The documents provide an unusually clear look into the process of developing pesticide regulations, which is typically done out of public view. It shows in detail how the EPA asked Bayer which regulations it wanted, received a response from Bayer, then put Bayer’s choices into a proposed federal rule.

Unpopular new policy comes as midterms loom and control of Congress could be decided by several Michigan races

Every day $1bn worth of goods crosses the river dividing Detroit, Michigan, and Windsor, Ontario, two largely blue-collar US and Canadian cities that have come to act as one in the creation of North America’s auto industry.

News this week of Donald Trump’s escalating trade spat with Canada has everyone worried. Political and economic leaders and observers labeled the move an act of “hubris” , blamed Trump’s “ego”, and called the escalation “insanity”.

Researchers tracked mother-child pairs for up to 11 years, finding Pfas mixtures may affect developing guts

Prenatal and early life exposure to Pfas mixtures is probably linked to higher levels of intestinal inflammation in children, new first-of-its-kind research shows. Intestinal inflammation can cause irritable bowel diseases, like ulcerative colitis, Crohn’s disease and colorectal cancer.

While Pfas has been linked to irritable bowel disease and intestinal inflammation in adults, the new peer-reviewed Mt Sinai study is the first to look at how the chemicals impact children during a critical developmental phase.

New US petition demands review of plans from tech companies amid fears of environmental destruction

Space datacenters proposed by SpaceX, Jeff Bezos’s Blue Origin and others would release staggering levels of pollution that would probably alter the Earth’s atmosphere and be “catastrophic” for the planet, space industry experts and environmental groups warn in a new petition demanding a review of their impacts.

Tech companies have collectively proposed millions of “orbital datacenters” and are pressing forward with plans, which require Federal Communications Commission (FCC) approval. Among other issues, pollution from satellites and rockets burning up upon re-entry appears to be accumulating in the stratosphere at alarming levels. The spacecraft release black soot, rare metals, aluminum oxides and other pollutants with unknown effects.

Trump administration urged to relist a species in ‘very, very serious trouble’ under Endangered Species Act

Climate change is driving a gray whale “catastrophic mortality event” in the Pacific Ocean as melting sea ice depletes food sources and the animals starve, environmental groups warn.

Meanwhile, a range of other issues, like ship strikes, oil spills, microplastic pollution, algal blooms and Russian harvesting are also probably contributing to the die-off that has nearly halved the whales’ estimated population. It fell from 20,000 in 2019 to fewer than 13,000 this year, and the deaths appear to be accelerating.

Babies exposed to higher levels of neurotoxin more likely to have difficulty controlling impulses later, research shows

Exposure to common air pollution may cause childhood obesity because it affects children’s ability to control impulse, new first-of-its-kind peer-reviewed research finds.

Particular matter 2.5 (PM2.5) is a neurotoxin that has been linked to obesity, and Mt Sinai researchers say they have for the first time identified impulse control as a potential pathway. The study found that babies exposed to higher levels of PM2.5 during their first year of life were more likely to develop difficulties with controlling impulses later in childhood.

Study suggests exposure to ‘forever chemicals’ may be a main driver of disease, formerly called PCOS, authors say

New research for the first time links prenatal exposure to Pfas “forever chemicals” with the development of polyendocrine metabolic ovarian syndrome (PMOS) later in life.

PMOS, formerly known as polycystic ovary syndrome (PCOS), is estimated to impact about 13% of women. Many cases are undiagnosed, and the disease’s cause largely remains a mystery.

Move is part of broad effort to open public lands to industry and other uses, threatening wildlife and ecosystems

The Trump administration is executing a controversial plan to allow dirt bikes, ATVs, trucks, snowmobiles and other off-road vehicles to drive through tens of millions of acres of public lands and national parks, which environmental groups warn threatens endangered species and the environment.

The plan’s opponents say the impacts will be wide-ranging and that the vehicles will likely destroy sensitive habitats, harm waterways, drive large predators like grizzly bears into contact with humans, and otherwise damage pristine public lands and parks.

Levels of Pfas in northern gannet eggs in Canada fell up to 74% over 55-year period of study

Levels of some of the most dangerous Pfas compounds have dramatically fallen in Canadian seabird eggs, which the authors of a new peer-reviewed study say illustrates how regulations are effective.

Researchers looked at Pfas levels in the eggs of northern gannets in the St Lawrence Seaway basin over a 55-year period. Pfas levels shot up from the 1960s through the peak of the chemicals’ use in the late 1990s and early aughts, then fell.

Opponents say administration’s plan prioritizes big agriculture at expense of wildlife and protected species

New legal action aims to head off a Trump administration plan to open up to 24m acres of federal lands to cattle grazing, which opponents characterized as a gift to big agriculture and said could cause a spike in deaths among already imperiled wolves, grizzlies, steelhead salmon and other wildlife.

The plan also calls for opening up parts of Grand Canyon national park, and other sensitive landscapes. Cattle destroy critical habitats for wildlife because they strip land bare of essential vegetation and pollute streams with feces, urine, sediment and carcasses. Meanwhile, park rangers and ranchers often kill grizzly bears and other predators who prey on cattle, despite that ranchers and the government pushed the cattle into the predators’ home range.

President is convening so-called ‘God squad’ to override provisions of Endangered Species Act for ‘national security’

Donald Trump is dispatching a so-called “God squad” of top officials to revoke protections for endangered species in the Gulf of Mexico, purportedly to protect national security by expanding oil and gas industry operations.

If successful, the administration may kill off dozens of protected species – from Rice’s whales and whooping cranes to sea turtles.

US test of 120 umbilical blood cord samples identified 42 Pfas compounds, which do not naturally break down

New peer-reviewed research shows fetuses likely have much higher levels of Pfas “forever chemicals” in their blood than previously thought.

Testing of umbilical cord blood typically looks for a small number of common Pfas compounds, like Pfoa and Pfos. However, thousands of Pfas exist, and a new Mount Sinai study tested 120 umbilical blood cord samples that were previously found to contain up to four compounds.

EPA rolls back rules as chemical firms claim provisions in RMP protection system too expensive to implement

The Trump administration is slowly dismantling the federal disaster management system that protects the nation from chemical catastrophes, such as fires and explosions at high-risk facilities.

The US Environmental Protection Agency’s Response Management Program (RMP) requires more than 12,500 high-risk facilities to develop protocols to prevent catastrophes, or limit fallout, and was largely designed to protect workers, first responders, and fence-line communities.

EPA’s records show one environmental consent decree filed in last year – 26 were filed in year one of first Trump term

Enforcement of environmental laws against major polluters has virtually ground to a halt under the Trump administration, a new analysis of Environmental Protection Agency records from January 2025 to January 2026 shows.

Major polluters typically include companies that are among the largest in the oil, gas, coal and chemical industries.

Corteva will discontinue a mixture of Agent Orange and glyphosate, but another of its herbicides will still use Vietnam war-era defoliant

The chemical giant Corteva will stop producing Enlist Duo, a herbicide considered to be among the most dangerous still used in the US by environmentalists because it contains a mix of Agent Orange and glyphosate, which have both been linked to cancer and widespread ecological damage.

The US military deployed Agent Orange, a chemical weapon, to destroy vegetation during the Vietnam war, causing serious health problems among soldiers and Vietnamese residents.

This article was amended on 9 February 2026 to add comment from a Corteva spokesperson.

Researchers found a new way to filter and destroy Pfas chemicals at 100 times the rate of current systems

New filtration technology developed by Rice University may absorb some Pfas “forever chemicals” at 100 times the rate previously possible, which could dramatically improve pollution control and speed remediations.

Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale.

Approval of legislation to ban Pfas would be major win for advocates pushing for safer gear alternatives across US

A new bill proposed in the New York city council would ban the use of toxic Pfas “forever chemicals” in protective gear worn by the city’s 11,000 firefighters.

The New York fire department is the nation’s largest firefighting force, and approval of the legislation would mark a major win for advocates who are pushing for safer “turnout gear” alternatives across the US. Massachusetts and Connecticut last year became the first states to ban the use of Pfas in turnout gear, and Illinois enacted a ban this year.
