GE French Fries, Coming to a Fast Food Restaurant Near You

The J.R. Simplot Company, giant potato supplier for McDonald’s, has spent years working on the perfect potato. Its new genetically engineered (GE) traits—which will be offered in five different varieties of potatoes—up for approval by the U.S. Department of Agriculture (USDA) has lower levels of a carbohydrate called acrylamide, which may cause cancer, and also has reduced black spot bruising. These potatoes will be used as frozen fries, potato chips and shoestrings, which make up approximately 50 percent of the potato market in the U.S., according to Simplot.
Both of the desired traits are achieved through the reduced expression of enzymes, affecting the amino acid asparagine for the low acrylamide trait and the enzyme polyphenol oxidase (PPO) for reduced bruising (the same way GE apples have been engineered not to brown). The problem is that an alteration in just one enzyme can unintentionally affect other plant characteristics as well as the plant’s health.
These GE potatoes will likely be fried using Monsanto’s new-and-improved omega-3 soybean oil, which will probably be marketed to lead consumers to believe that the bio-engineered combination is “healthy” fried food. A low-acrylamide potato may reduce levels of just one of the harmful chemicals brought out by frying foods but there are other dangerous compounds that are produced when food is heated to very high temperatures, including advanced glycation endproducts, or AGEs, which can lead to “chronic inflammation and oxidative stress,” (also linked to cancer). And of course this new fried “goodness” doesn’t address the high-calorie and low-nutrient content that make fried potatoes unhealthy in the first place.
Historically, GE potatoes have not fared so well in the marketplace. Monsanto’s NewLeaf GE potatoes were approved in 1995, but the company pulled its potatoes from the market in 2001. If approved, these potatoes may face the same fate and never make it into happy meals across America. But these potatoes could also be exported, since Simplot has submitted its petition for approval to Canada, Mexico, Japan and South Korea.
The USDA will be seeking comments until July 2 and we intend to tell them to further review the potential health effects of these GE potatoes.

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

A NASA spacecraft has successfully collected a sample from the Bennu asteroid more than 200 million miles away from Earth. The samples were safely stored and will be preserved for scientists to study after the spacecraft drops them over the Utah desert in 2023, according to the Associated Press (AP).
