Laura Minquini Interview
Laura Minquini is not a scientist, but that hasn’t stopped her from joining the front lines of the war on aging: specifically, female reproductive aging. Several years ago, after a successful stint in consumer technology, Laura discovered the longevity field when decentralized science was all the rage. Inspired by VitaDAO’s success, she founded AthenaDAO, a...
Cilia on a neuron
A team of researchers has written a paper with a surprising finding: that many of the benefits of caloric restriction and increased NAD+ may be due to their effects on the cilia of hypothalamic neurons. Neuronal cilia have a relationship to overall health Nicotinamide Adenine Dinucleotide (NAD): Benefits and ResearchNicotinamide adenine dinucleotide (NAD) is a...
CT Scan Robot
A new study suggests that CT scans can provide information about a wide range of conditions, including some not typically diagnosed through imaging. Direct comparison with human radiologists is the next step [1]. Getting more from a scan A CT scan’s goal is usually to answer a concrete clinical question, such as what is causing...
Endothelial cells
Researchers publishing in Aging Cell have found that the regulatory protein MTR4 fights DNA damage in the blood vessel lining but decreases with aging. Vulnerable by nature This paper begins by noting the properties, and aging, of vascular endothelial cells (VECs), which line the blood vessels and govern their permeability [1]. As these cells are...
Bone structure
A new study links STING-mediated signals from marrow fat cells to inflammation and declining NAD⁺ levels in bone-forming cells. Interrupting this pathway helped preserve aging bone [1]. Making old bones Our bones live a complex life, as they are constantly remodeled: cells called osteoclasts break down existing bone, while osteoblasts build new bone. Osteoblasts arise...
Mechanical cell
Reviewers publishing in Biology have elucidated SIRT1 functional reserve as an aspect of aging, describing how its depletion is an upstream cause of age-related disorders at the cellular level and explaining why many prospective therapies that increase SIRT1 and NAD+ have not had promising results. Managing a dangerous byproduct Reactive oxygen species (ROS) are necessarily...
