For many years, some members of the scientific community have been absolutely engrossed in trying to solve one of the biggest health conundrums in the United States: how to get more people to donate their organs. And if that can’t happen on a grand scale, well, scientists are turning to cloned pigs for organs.
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.
Doctors and researchers are in a race against the clock to find new antibiotics and alternatives to antibiotics as the problem of drug-resistance worsens and spreads. One bacterial superbug in particular which has researchers especially worried is Clostridium difficile, or C. difficile – a bacterium which can cause fatal infections in hospitals and nursing homes.
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.
A Penn State University researcher has created a genetically modified mushroom that is now at the center of controversy over GMO regulations of genetically modified creations.
Researchers in China claim they have successfully added mutations to human embryos which make them HIV-proof.
Scientists in Britain have recently been given the green light to edit the genes of human embryos for research, leading to fears the practice could lead to “designer babies.”
Chinese scientists set off a firestorm of controversy a year ago when they announced they had begun genetically modifying human embryos. Now, British researcher Kathy Niakan, from London’s Francis Crick Institute has a received a license to carry out similar experiments.
