Why Not to Fear Genetically Modified Food
Biochemist Dr. Simon Easterbrook-Smith says there is no difference between eating a tomato containing a GM protein from fish, for example, and eating an unmodified tomato with a piece of fish.
What's the Latests Development?
Dr. Simon Easterbrook-Smith leads a team of biochemists at the University of Sydney in Australia; the doctor says his team's research into genetic modification has given insight into diseases like diabetes, Parkinson’s and Alzheimer’s. Easterbrook-Smith says research has convinced him that consuming genetically modified foods represents no threat to the population's general health. What's more, solving difficult problems like world hunger will depend on a robust supply of GM crops: "Feeding the world’s growing population is a big challenge; the world will need 70 to 100 per cent more food by 2050. GM crops can make an important contribution to this," says Easterbrook-Smith.
What's the Big Idea?
Dangerous science or brilliant discovery? Genetically modified foods have drawn the ire of traditionalists and praise from futurists, but the science behind GM foods is very new and conclusions about the long-term health consequences of consuming them is difficult to come by. Dr. Easterbrook-Smith insists that, beyond food, serious medical problems could be solved through the development and use of genetically modified foods: "Most of the insulin used to treat people with Type I diabetes is made in GM yeast. The HPV vaccine, which protects women against cervical cancer, is made using GM methods."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
