On the 23rd of this month, Dr. David Sinclair did an Ask Me Anything over at the Futurology subreddit in support of the NAD+ Mouse Project on Lifespan.io. There were a range of interesting questions from the community about his work in aging research, particularly the role of NAD+ in aging.

Dr. David A. Sinclair is a Professor in the Department of Genetics at Harvard Medical School and a co-joint Professor in the Department of Physiology and Pharmacology at the University of New South Wales. He is the co-Director of the Paul F. Glenn Laboratories for the Biological Mechanisms of Aging and a Senior Scholar of the Ellison Medical Foundation. He obtained his Ph.D. in Molecular Genetics at the University of New South Wales, Sydney in 1995. He worked as a postdoctoral researcher at M.I.T. with Dr. Leonard Guarente; there, he co-discovered a cause of aging for yeast as well as the role of Sir2 in epigenetic changes driven by genome instability.

More recently, he has been in the spotlight for his work with NAD+ precursors and their role in aging and has been helping to develop therapies that replace NAD+, which is lost with aging, in order to delay the diseases of old age. Below are a selection of questions and answers from the AMA, and we urge you to head over to Reddit Futurology to check out the other questions that people asked.

The brilliant Prof Judith Campisi from Buck Institute on Aging on senescence, senolytics, healthspan and more, a new interview.

Anti-aging pioneer Judith Campisi explains how a recent breakthrough could ward off age-related disease.

Colour blindness, otherwise known as colour vision deficiency, affects around 8% of men.

Flu sufferers now have a new option for relieving symptoms. Xofluza (baloxavir marboxil), a single-dose, oral prescription drug, was approved by the US Food and Drug Administration on Wednesday. The antiviral is the first new flu treatment approved by the FDA in nearly 20 years, FDA Commissioner Dr. Scott Gottlieb said in a statement.

“With thousands of people getting the flu every year, and many people becoming seriously ill, having safe and effective treatment alternatives is critical,” said Gottlieb.

The pill is intended for patients who are 12 or older and who have had symptoms for no more than 48 hours. When patients with the flu, a respiratory illness, are treated within 48 hours of becoming sick, antiviral drugs can reduce symptoms and duration of illness, according to the FDA.

A study suggests cardiorespiratory fitness is linked to a longer life, suggesting no exercise is worse for health than smoking or diabetes.

The genome editing system CRISPR has become a hugely important tool in medical research, and could ultimately have a significant impact in fields such as agriculture, bioenergy, and food security.

Many mutations accumulate in the esophagus as we age.

Scientists at the MRC Cancer Unit of the Wellcome Sanger Institute and other departments of the University of Cambridge discovered that healthy esophageal tissue accumulates very high numbers of mutations with age, to the point that, by the time middle age is reached, it is likely to contain more cells with a particular mutation than cells without it [1].

Judith Campisi as a speaker for the 2019 Undoing Aging Conference.

At Lawrence Berkeley National Laboratory and at the Buck Institute for Research on Aging, Dr. Judith Campisi established a broad program to understand the relationship between aging and age-related disease.

Judith Campisi says: “Aging research has entered an era of unprecedented hope for interventions that can prevent, delay and, in some cases, reverse much of the functional decline that is a hallmark of aging. There is still a lot of research to be done! I am delighted to be among the speakers at Undoing Aging 2019, where I will discuss the opportunities and challenges of our recent research.”
