A controversial pesticide test that would have resulted in the deaths of 36 beagles has been stopped, the Humane Society of the United States (HSUS) and the company behind the test announced Monday. The announcement comes less than a week after HSUS made the test public when it released the results of an investigation into animal testing at Charles River Laboratories in Michigan.

"We have immediately ended the study that was the subject of attention last week and will make every effort to rehome the animals that were part of the study," Corteva Agriscience, the agriculture division of DowDupont, said in a statement announcing its decision.

Thirty-six beagles are in danger of being euthanized at the end of a pesticide test, the Humane Society of the United States (HSUS) revealed Tuesday.

The beagles' potential fate was only one of several shocking revelations uncovered by an almost 100-day HSUS investigation into the testing of beagles and hounds at Charles River Laboratories in Michigan.

A new study has found that exposure to certain pesticides can alter bees' genes, leading researchers to call for tougher regulations on the widely-used chemicals.

The study, published Wednesday in Molecular Ecology, looked at the impact of two neonicotinoid pesticides on bumblebee populations and found that they impacted genes involved in a variety of important biological processes.

Unlike organic packaged foods, conventional packaged food contains thousands of poorly regulated food chemicals, according to a new analysis by the Environmental Working Group.

"Although many consumers choose organic to avoid toxic pesticides, few know that federal rules dramatically limit the use of synthetic substances in organic food," said EWG nutritionist Dawn Undurraga, one of the authors of the report.

A hundred years ago, a person wandering the back roads of coastal New England might have come across an odd sight: at the edge of a farmyard, cheek by jowl with pigs and chickens and cows, a tall pole topped with a massive stick nest. And standing guard in the nest, a large brown-backed, white-headed wild bird of prey — an osprey (Pandion haliaetus).

Farmers in this region knew that nesting ospreys were vigilant watchdogs, quick to chase "chicken-hawks" and other predators away. But as fish eaters, ospreys were no threat to farm animals. And they were trusting enough to live comfortably near humans. So farmers lured them by building them places to nest — generally, an old wagon wheel atop a bare pole, mimicking the dead trees in which ospreys had nested for millennia.

The U.S. Environmental Protection Agency (EPA) in April 2018 proposed relaxing standards related to how it assesses the effects of exposure to low levels of toxic chemicals on public health.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.

The U.S. Environmental Protection Agency (EPA) reported last week that in 2018 it issued so-called "emergency" approvals to spray sulfoxaflor—an insecticide the agency considers "very highly toxic" to bees—on more than 16 million acres of crops known to attract bees.

A new meta-analysis of glyphosate suggests that people who are highly exposed to the popular herbicide have a 41 percent increased risk of developing non-Hodgkin lymphoma (NHL).

Glyphosate, the active ingredient in Roundup, is the world's most widely used weedkiller and has been surrounded by controversy ever since the International Agency for Research on Cancer classified it as "probably carcinogenic to humans" in 2015.

More than 40 percent of the world's insects could go extinct in the next few decades, according to a report that lead author Francisco Sánchez-Bayo told CNN was the first global review of the threats facing the class that makes up 70 percent of earth's animals.

A third of insects are endangered species, and they are going extinct at a rate eight times that of birds, mammals and reptiles. That amounts to a loss of 2.5 percent of insect mass every year over the last three decades.

Health and labor organizations will have to argue again in court that chlorpyrifos, a brain-damaging pesticide, must be banned from all food uses, the 9th Circuit Court of Appeals ruled Wednesday. The decision comes four months after Andrew Wheeler's U.S. Environmental Protection Agency (EPA) asked the court to rehear the case either by the three-judge panel that originally banned chlorpyrifos in 2018, or by a panel of 11 judges.

Yet again, our government scientists—the oft neglected but so important brain trust of our nation—bring the public some very important new data. Pesticide water monitoring experts at the U.S. Geological Survey (USGS) paired up with scientists from the University of Iowa in a federally funded collaboration to track neonicotinoid pesticides or " neonics" in tap water, including the potential to form chlorinated disinfection byproducts (DBPs) from the pesticides and their metabolites that may be more toxic than the original compounds. And the news isn't good.
