Study: CRISPR Gene-Editing Ignites Tons of Unintentional Genetic Mutations

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.

Gene-Editing Technology may Replace Antibiotics in the Future

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.

Britain’s Fertility Regulator has Approved 3-Parent GMO Babies

The UK’s fertility regulator has given approval for the “cautious use” of techniques to create a baby using the DNA of 3 people. [1]
The Human Fertilisation and Embryology Authority (HFEA) announced its “historic” decision December 15 and said that it would begin accepting applications from fertility clinics that wish to become licensed to perform the procedure. The HFEA said 3-parent baby technique, as it is commonly called, will help prevent a small number of children from inheriting potentially fatal diseases from their mothers. [2]

Genes for Antibiotic-Resistant Bacteria Are Found in Beijing Smog

Public health experts have warned that antibiotic resistance could claim 10 million people each year by 2050. In early December 2016, researchers said they had discovered that livestock had become resistant to a class of antibiotics used only in humans. Now scientists have found the genes that make bacteria resistant to antibiotics in polluted air in Beijing, China. [1]

First Human Injected with Controversial Genetically Modified Genes

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.”
