The US EPA is the federal agency that writes and enforces regulations on air and water quality, pollution limits, and emissions standards for industry.
University of Kentucky researchers found essential-oil cockroach sprays killed over 96% on direct contact, but most dried residues killed under 10%. The Scientific Reports study aged residues on ceramic tile and pine wood for up to a month.

FIU researchers report a PFAS water test that takes 30 minutes instead of more than six hours. It covers 39 of the 40 EPA-listed compounds and arrives as EPA rules require continuous monitoring in public water systems.
Reality
Cornell undergraduates screened 500-plus samples from 300 bodies of water for 24 PFAS and mapped the results. Sites over New York guidance values are largely in standing water near airports and fire training stations.
Reality
Local authorities have ordered the operators of Milpitas' Newby Island landfill to track odour chemicals with drones and monitors. The US EPA does not regulate odour as a pollutant, the BBC reports, so each place decides what its sensors must lead to.
Reality
NJIT researchers found TFA, an ultra-short-chain PFAS, in over 91% of New Jersey tap-water samples and nearly 80% of bottled drinks. Routine PFAS testing has largely missed compounds this small, and the 113-sample survey puts numbers on that gap.

Benjamin Santer's team argues more than 30 years of fingerprint research make the human-warming case stronger than in 2009. Their Earth's Future review answers a July 2025 Department of Energy report that questioned the science behind the EPA's Endangerment Finding.
Reality
University of Miami researchers found the National Cattlemen's Association knew by 1989 that cattle methane contributed to global warming. Its records, analysed in PLOS Climate, show a response built on public relations to keep consumers buying beef.
Reality
Researchers found significantly higher levels of 19 potentially toxic chemicals in shed baby teeth from 22 children with autism than from 16 controls. With 38 children, the pilot can point a larger study toward candidate chemicals but cannot show that any of them causes autism.
Reality
Ritter, founder of lead-testing firm Fluoro-Spec, has scored childhood lead risk for all 83,388 US census tracts from housing age and poverty. The map is meant to show health departments where blood testing and home inspections should go first, since neighborhood lead data are sparse.
Reality
California Waste Solutions plans to spend more than $500 million on a Ho Chi Minh City plant that would turn 3,000 tons of trash a day into power. The project still needs permits, and the company's president says it has proved the approach at a much smaller level.
Reality
Colorado State University's open-source smoke logger, worn on mule deer collars, recorded air quality differing tenfold from the nearest monitoring stations. No deer in this year's Colorado and Utah deployment met unhealthy smoke, so the behavioral question the device was built for is still open.
Reality
Jaguar showed the production Type 01 in New York on Tuesday, claiming up to 400 miles of EPA range and 1,030 PS from three motors. Owners will judge it on the parts they touch every drive, and so far the evidence is launch specs and a ride in the passenger seat.

Researchers from PSE Healthy Energy, Stanford and NYU found NO2 above the EPA's outdoor one-hour limit in about 70% of gas restaurant kitchens they measured. The three all-electric kitchens stayed within every pollution guideline during cooking hours, so the choice of appliance also determines how much pollution kitchen workers breathe.
Reality
Virginia Cornish's Columbia team is building a yeast-and-chip sensor for PFAS, the chemicals found in nearly half of US municipal water supplies. Utilities would get a handheld, real-time reading, though the yeast meant to detect PFOA and PFOS are still being engineered.
Reality
Ford is funding DTE Energy's $194 million Cold Creek solar park, 100 megawatts toward its pledge to buy up to 650 megawatts of Michigan clean power. Buying through a utility green tariff ties Ford's money to a specific new plant and ties its carbon-free factory target to DTE's build schedule.
Reality
Supreme Court justices hear Boulder's suit against ExxonMobil and Suncor on Monday, a case that could settle dozens of similar local climate claims. At issue for producers is whether climate costs get fought jurisdiction by jurisdiction in state courts or left to federal regulators.
Reality
EPA water chief Jess Kramer says attacks on US water utilities have risen several fold, citing unchanged passwords and system details left online. EPA keeps finding basic weak points, and officials say many utilities lack the staff and investment to close them.
Reality
The FBI and EPA's advisory I-073026-PSA blames a water-sector campaign across at least seven states on MicroLogix controllers left reachable on the open internet. The remedy they describe is network placement.
Reality
Ohio lawmakers passed a 90-day fuel tax holiday that lifts the 47-cent diesel tax, bringing relief to about a third of U.S. states, per an AP review. Each state sets its own terms and end dates, so a multi-state fleet's fuel budget can now change within weeks.
Reality
Ten NASA-funded monitors logged three years of black carbon in Ethiopia's capital. The peaks track rush hour and holidays, which is not what an annual average measures.
