Nazi.world will probably pull this unless you post it to progressive politics. Not that anyone with the attention span of gnats will watch it, just saying.

The entire video, including q&a is extremely important. Thanks for sharing.

Unlike traditional approaches, this new technology does not require delivery of exogenous editing enzymes. Using only a segment of engineered RNA molecules, it can mobilize key enzymes that naturally exist in human cells to achieve precise editing of target RNA. The system is simple with high safety, imposing minimal delivery burden.

The team has collaborated with Kunming University of Science and Technology in Southwest China, Shanghai Jiao Tong University in East China and other institutions to develop candidate drugs. Three pediatric patients who had received treatment all demonstrated significant and sustained improvements in motor function during the one-year follow-up period.

Scientists discover a hydraulic link between the abdomen and the brain (www.psypost.org)

A recent study published in Nature Neuroscience suggests that the brain is more mechanically connected to the body than previously appreciated. Scientists found that abdominal muscle contractions compress blood vessels connected to the spine and brain, pushing fluid that gently moves the brain within the skull. This physical swaying provides evidence for how exercise might benefit brain health by washing away cellular waste.

Scientists set out to understand the specific mechanical origins of brain motion in awake animals. The central nervous system is encased in thick bone, making it seem isolated from the physical forces of the rest of the body. However, the work builds on previous studies detailing how sleep and neuron loss can influence how and when cerebrospinal fluid flushes through the brain, according to Patrick Drew, a professor of engineering science and mechanics, neurosurgery, biology and biomedical engineering at Penn State.

“Our research explains how just moving around might serve as an important physiological mechanism promoting brain health,” said Drew, corresponding author on the paper. “In this study, we found that when the abdominal muscles contract, they push blood from the abdomen into the spinal cord, just like in a hydraulic system, applying pressure to the brain and making it move.”
