Scientists from Harvard Medical School successfully restored vision in mice by reversing aging in retinal cells. The work shows that it may be possible to safely reprogram complex tissues to an earlier age. Reversing the cells' age resulted in reversing vision loss in animals with a condition similar to human glaucoma. It is the first successful attempt to reverse glaucoma-induced vision loss. The treatment involved using an adeno-associated virus as a vehicle to deliver three youth-restoring genes. It is based on a new theory about aging, which postulates that changes to the epigenome over time causes cells to read the wrong genes and malfunction.

The golden rule is to value your reviewer's time, allowing them to focus on interesting parts of your code rather than requiring them to untangle code or police simple mistakes.
A team of scientists used high-energy X-rays to analyze ancient Egyptian papyri fragments and found lead compounds in both the red and black inks used. This is evidence that lead was added for its fast-drying properties rather than for its pigmentation. Painters in Europe used a similar technique when developing oil paints in the 15th-century, except that the Egyptians discovered it 1,400 years earlier. Synchrotron radiation is useful for analyzing art and other priceless artifacts due to its high-energy and short wavelengths. Ink has been used to write for thousands of years, and revealing the secrets of ancient ink technology contributes to our knowledge of the origin of writing practices.
