‘Extreme Levels’ of Monsanto’s Roundup Herbicide Found in Soy Plants

A new study led by scientists from the Arctic University of Norway has detected “extreme levels” of Roundup, the agricultural herbicide manufactured by Monsanto, in genetically engineered (GE) soy.

The herbicide has triggered a cycle of super weeds resistant to Roundup, which then means more Roundup is needed to try to kill the hardy weeds.

The study, coming out in June’s issue of Food Chemistry and available online, looked at 31 different soybean plants on Iowa farms and compared the accumulation of pesticides and herbicides on plants in three categories: GE “Roundup Ready” soy, conventionally produced (not GE) soy, and soy cultivated using organic practices. They found high levels of Roundup on 70 percent of GE soy plants.

Crop scientists have genetically engineered soy to survive blasts of Roundup so farmers can spray this chemical near crops to get rid of weeds. But some so-called “super weeds” resistant to Roundup have developed. In turn, some farmers use yet more Roundup to try to kill those hardy weeds. This leads to more Roundup chemicals being found on soybeans and ultimately in the food supply.

Who says when Roundup contamination can be considered “extreme?” Monsanto itself. In 1999, the chemical giant defined an “extreme level” of the herbicide as 5.6 milligrams per kilogram of plant weight.

Astonishingly, the Norwegian scientists found a whopping nine milligrams of Roundup per kilogram, on average. What it boils down to is this: every time we eat GE soy we are taking a dose of Roundup with it. This is alarming, because Roundup has been found to be hazardous to human health and sometimes kills human cells. The authors conclude:

This study demonstrated that Roundup Ready [GE]-soy may have high residue levels of glyphosate […] and also that different agricultural practices may result in a markedly different nutritional composition of soybeans […] Lack of data on pesticide residues in major crop plants is a serious gap of knowledge with potential consequences for human and animal health.

Other research has detected Roundup residues in animals and people.

A study led by German researchers found high concentrations of glyphosate, the active ingredient in Roundup, in the urine of dairy cows and humans. This study, published in January in the journal Environmental & Analytical Toxicology, concluded that “the presence of glyphosate residues in both humans and animals could haul the entire population towards numerous health hazards.”

Big Ag wants us to believe that there is no difference between GE and conventional crops, but mounting research tells us that just isn’t true.

Just in time for Halloween, scientists at Cornell University have published some frightening research, especially if you're an insect!

The ghoulishly named ogre-faced spider can "hear" with its legs and use that ability to catch insects flying behind it, the study published in Current Biology Thursday concluded.

"Spiders are sensitive to airborne sound," Cornell professor emeritus Dr. Charles Walcott, who was not involved with the study, told the Cornell Chronicle. "That's the big message really."

The net-casting, ogre-faced spider (Deinopis spinosa) has a unique hunting strategy, as study coauthor Cornell University postdoctoral researcher Jay Stafstrom explained in a video.

They hunt only at night using a special kind of web: an A-shaped frame made from non-sticky silk that supports a fuzzy rectangle that they hold with their front forelegs and use to trap prey.

They do this in two ways. In a maneuver called a "forward strike," they pounce down on prey moving beneath them on the ground. This is enabled by their large eyes — the biggest of any spider. These eyes give them 2,000 times the night vision that we have, Science explained.

But the spiders can also perform a move called the "backward strike," Stafstrom explained, in which they reach their legs behind them and catch insects flying through the air.

"So here comes a flying bug and somehow the spider gets information on the sound direction and its distance. The spiders time the 200-millisecond leap if the fly is within its capture zone – much like an over-the-shoulder catch. The spider gets its prey. They're accurate," coauthor Ronald Hoy, the D & D Joslovitz Merksamer Professor in the Department of Neurobiology and Behavior in the College of Arts and Sciences, told the Cornell Chronicle.

What the researchers wanted to understand was how the spiders could tell what was moving behind them when they have no ears.

It isn't a question of peripheral vision. In a 2016 study, the same team blindfolded the spiders and sent them out to hunt, Science explained. This prevented the spiders from making their forward strikes, but they were still able to catch prey using the backwards strike. The researchers thought the spiders were "hearing" their prey with the sensors on the tips of their legs. All spiders have these sensors, but scientists had previously thought they were only able to detect vibrations through surfaces, not sounds in the air.

To test how well the ogre-faced spiders could actually hear, the researchers conducted a two-part experiment.

First, they inserted electrodes into removed spider legs and into the brains of intact spiders. They put the spiders and the legs into a vibration-proof booth and played sounds from two meters (approximately 6.5 feet) away. The spiders and the legs responded to sounds from 100 hertz to 10,000 hertz.

Next, they played the five sounds that had triggered the biggest response to 25 spiders in the wild and 51 spiders in the lab. More than half the spiders did the "backward strike" move when they heard sounds that have a lower frequency similar to insect wing beats. When the higher frequency sounds were played, the spiders did not move. This suggests the higher frequencies may mimic the sounds of predators like birds.

University of Cincinnati spider behavioral ecologist George Uetz told Science that the results were a "surprise" that indicated science has much to learn about spiders as a whole. Because all spiders have these receptors on their legs, it is possible that all spiders can hear. This theory was first put forward by Walcott 60 years ago, but was dismissed at the time, according to the Cornell Chronicle. But studies of other spiders have turned up further evidence since. A 2016 study found that a kind of jumping spider can pick up sonic vibrations in the air.

"We don't know diddly about spiders," Uetz told Science. "They are much more complex than people ever thought they were."

Learning more provides scientists with an opportunity to study their sensory abilities in order to improve technology like bio-sensors, directional microphones and visual processing algorithms, Stafstrom told CNN.

Hoy agreed.

"The point is any understudied, underappreciated group has fascinating lives, even a yucky spider, and we can learn something from it," he told CNN.
