Study: World's Largest Monarch Population Could Disappear in 20 Years. For Immediate Release, March 21, 2016 Study: World's Largest Monarch Population Could Disappear in 20 Years 84 Percent Decline Driven by Loss of Milkweed Due to Genetically Engineered Crops WASHINGTON— The eastern migratory population of the monarch butterfly — which includes 99 percent of the world’s monarchs — is at high risk of extinction within two decades unless the population rebounds dramatically, according to a new study published today by Nature Scientific Reports.

The study from the U.S. Geological Survey and other scientists predicts an 11 percent to 57 percent chance of extinction for the monarch migration in the next 20 years.

WASHINGTON – U.S. farmers can grow more corn than ever before thanks to genetic modifications and improved planting techniques, but the crops are also increasingly vulnerable to drought, researchers recently said.

The study in the journal Science found that “densely planted corn appears to be unexpectedly more sensitive to water scarcity,” raising concerns about future food supply as the planet warms. The United States is the largest exporter of corn in the world, shipping about 40 percent of the world’s corn. In recent years, most commercially produced corn has been modified with new traits that make roots better able to access water and build in pest resistance. That has allowed farmers to plant more corn and set the plants more closely together than they could in the past, resulting in higher yields.

If predictions for future climate in the midwestern U.S. — known as the Corn Belt — are correct, then corn yields could fall 15 to 30 percent over the next half century, scientists said.

Ask Umbra: Are GMO sugar beets bad for the birds?

Q. Dear Umbra, I feed hummingbirds a syrup made of 1 cup sugar and 4 cups water. I recently read an article about GMO sugar beets in the U.S. And that beet sugar is sold as granulated sugar and not labeled to indicate beet as opposed to cane sugar. Susan W.Egremont, Mass.

Genetically engineered food: Allergic to regulations?

I’m looping back today to look more deeply at this. It gets a bit technical, but here’s the deal: A few moments of pain here and there, and in exchange you’ll get past the talking points and come away with a genuine grasp of the risks of GM allergenicity. Deal? All right. To you, the select and honored 10 percent still here, I bow. Devons nous laisser les géants des biotechnologies détruire le maïs mexicain ? Genetic Engineers Blast GM Crops.

In discussions with friends who have only vague ideas about all the GMO (genetically modified organisms) controversy, I have often wished for a handy guide to the main arguments, pro and con.

Now I finally have it, thanks to a new report: “GMO Myths and Truths: An evidence-based examination of the claims made for the safety and efficacy of genetically modified crops.” The report’s authors include two genetic engineers and a writer and editor with extensive knowledge of the issues.

Blue Strawberries Raise More GMO Questions. The GM Apple That Won't Turn Brown. Apples have become the latest controversial entry into the genetically modified food debate, following a July 12 New York Times piece written by Andrew Pollack.

Okanagan Specialty Fruits, a small British Columbia company, wants to start marketing a non-browning apple, and it has applied for approval in Canada and in the United States. The Arctic apple, available so far in the Golden Delicious and Granny Smith varieties, contains an extra copy of a gene which interferes with the enzymatic activity that causes browning. The enzyme is polyphenol oxidase.

According to Neal Carter, founder and president of Okanagan Specialty Fruits, the non-browning Arctic apple is just what consumers are looking for.
