Designer protein helps paralyzed mice walk again in breakthrough study
In a new study, German scientists have restored the ability to walk in mice that had been paralyzed after a complete spinal cord injury. The team created a “designer” signaling protein and injected it into the animals’ brains, stimulating their nerve cells to regenerate and share the recipe to make the protein.

Editing the DNA of Human Embryos Could Protect Us From Future Pandemics
Hollywood blockbusters such as X-men, Gattaca and Jurassic World have explored the intriguing concept of “germline genome editing” – a biomolecular technique that can alter the DNA of sperm, eggs or embryos. If you remove a gene that causes a certain disease in an embryo, not only will the baby be free of the disease when born – so will its descendants. The technique is, however, controversial
