A 2,000-Year-Old Sarcophagus Was Unsealed—and the Mummy Inside Is Mind-Blowing Experts working in the Tomb of Cerberus in Naples unsealed a 2,000-year-old sarcophagus—and the mummy inside was shockingly well-preserved.

“As DNA analysis of the remains is ongoing, the team also continues to analyze the organic substances, including pollen, found within the sarcophagus.” #DNA #ISOGG #Cerberus #ancientDNA

New study shows Alzheimer’s disease can be reversed to achieve full neurological recovery—not just prevented or slowed—in animal models | CWRU Newsroom | Case Western Reserve University For more than a century, people have considered Alzheimer's disease (AD) an irreversible illness. Consequently, research has focused on preventing or ...

“The pharmacological approach in this study, however, uses a pharmacologic agent (P7C3-A20) that enables cells to maintain their proper balance of #NAD+ under conditions of otherwise overwhelming stress, without elevating NAD+ to supraphysiologic levels.” #ISOGG #DNA case.edu/news/new-stu...
