A group of scientists in Oregon have edited the genes of human embryos for the first time in the United States, using CRISPR-Cas9, a cut-and-paste gene-editing tool. [1]
The experiments were conducted by Shoukhrat Mitalipov and colleagues at Oregon Health & Science University in Portland. The single-celled embryos Mitalipov edited were discarded after the experiments to ensure they could not become too developed.
The U.S. Environmental Protection Agency (EPA) recently and quietly approved Monsanto’s new genetic engineering technology, known as RNAi. [1]
The insecticide DvSnf7 dsRNA is not sprayed on crops. Instead, instructions for manufacturing it in the DNA of the crop itself must be encoded in crops. The plants’ self-made DvSnf7 dsRNA disrupts a crucial gene in western corn rootworms – a major threat to corn – and kills the pests.
A new study shows that CRISPR gene editing can cause hundreds of unintended gene mutations. DNA tinkering is part of a long-standing program, originally funded by the Rockefellers, to transform the human race into two distinct species: one to serve and the other to command. [...]
CRISPR-Cas9 gene-editing has been hailed as one of the biggest scientific breakthroughs of our lifetime. The technology is often called “molecular scissors” for its ability to “cut and paste” pieces of DNA, thereby removing unwanted traits and replacing them with more desirable ones. CRISPR is being celebrated for its accuracy, but a recent study sheds light on some imperfections surrounding the technology that we should be aware of.
There are test-tube babies and three-parent babies, and both generate plenty of controversy. But as it stands, making a baby still requires an egg from a mother and sperm cells from a father. Scientists say that won’t always be the case, though, because someday it will likely be possible to make babies from skin cells alone.
Last year, scientists in Japan revealed that mice had been born of eggs made from a parent’s skin cells, and researchers believe the same technique can one day be used in humans. [1]
For the first time in history, a human has been injected with genes edited using the CRISPR-Cas9 method. [1]
The experiment took place on 28 October 2016, when a team of Chinese scientists, led by oncologist Lu You at Sichuan University in Chengdu, delivered the genetically modified (GM) cells into a patient with aggressive lung cancer as part of a clinical trial at the West China Hospital in Chengdu. [2]
To protect the patient’s privacy, the details of the trial have not been released; but Lu said the trial “went smoothly.”
Monsanto announced last week that it licensed the CRISPR-Cas9 gene-editing tool from the Broad Institute in Boston for use in seed development. The technology will allow the agritech giant to edit crops’ DNA by “snipping” away undesirable traits – or adding in more desirable ones – of the plants’ genetic codes. Frankenfood? [1]

In what is believed to be a first, a Swedish scientist has attempted to edit DNA in healthy human embryos. [1]
Developmental biologist Fredrik Lanner is the first known researcher to conduct the experiment, which has long been considered taboo due to safety and ethical concerns.
A lot of people are willing to spend a few extra bucks to buy organic produce and antibiotic-free meat these days, while others aren’t too worried about eating foods made with genetically modified ingredients or sprayed with pesticides. Well, it seems that scientists recently made history when they served up – and ate – the first full-meal consisting of genetically engineered food using CRISPR technology.
by Jonathan Latham, PhD The National Academy of Sciences needs to urgently address its one-sided work on GMOs say public-interest groups, farmer organisations, and academics. In a letter sent to the Academy’s president today, dozens ...
