(Phys.org)—A team of researchers working at West China Hospital in Chengdu has for the first time injected CRISPR–Cas9 edited cells into a human test subject. Nature reports that the procedure occurred on October 28, and that thus far, the patient is doing “fine.”

Modified cells have been injected into human subjects before, of course, but using different techniques. CRISPR-Cas 9 is considered to be a more efficient approach. In this new effort, the researchers isolated immune cells retrieved from a blood sample, then used CRISPR-Cas9 to locate and disable the PD-1 protein in them, which prior research has shown slows an immune response by a cell. The idea is that disabling the protein will allow the immune system to put up more of a fight against tumor growth. The edited cells were placed in a container where they were fed and allowed to multiply—the entire collection was then gathered and injected into a patient suffering from a type of lung cancer that had not responded to any other treatment type.

The CRISPR technique involves using an RNA guide that binds to a particular DNA sequence and an enzyme (the Cas9 part) that can cut strands of DNA at preselected spots, allowing for removing strands or adding new ones.

In an experiment at the Air Force Research Laboratory, Wright-Patterson Air Force Base in Ohio, researchers have found that transcranial direct-current stimulation (tDCS) of the brain can improve people’s multitasking skills and help avoid the drop in performance that comes with information overload.

The study was reported in a pre-publication paper in the open-access journal Frontiers of Human Neuroscience. It was motivated by the observation that various Air Force operations such as remotely piloted and manned aircraft operations require a human operator to monitor and respond to multiple events simultaneously over a long period of time. “With the monotonous nature of these tasks, the operator’s performance may decline shortly after their work shift commences,” according to the researchers.

Scientists have discovered a new way to edit DNA that could fix “broken genes” in the brain, cure previously incurable diseases and potentially even extend the human lifespan.

The breakthrough – described as a “holy grail” of genetics – was used to partially restore the sight of rats blinded by a condition which also affects humans.

Previously researchers were not able to make changes to DNA in eye, brain, heart and liver tissues.

Progress for heart disease!

For the first time, a new drug given along with a cholesterol-lowering statin medicine has proved able to shrink plaque that is clogging arteries, potentially giving a way to undo some of the damage of heart disease.

The difference was very small but doctors hope it will grow with longer treatment, and any reversal or stabilization of disease would be a win for patients and a long-sought goal.
