Age, Sequence, and DNA Methylation are Culprits of Lactose IntoleranceMay 20, 2016While fine wine and aged cheese are culinary delights, some of us who dine on dairy often start to go a bit ‘sour’ with age and develop lactose intolerance. Thankfully, to aid our mental digestion of such a foul fate, a collaborative effort between Toronto and Lithuania has shown the molecular mechanism of why we can […]
Stress Accelerates Epigenetic AgeingDecember 18, 2015The epigenetic clock has developed faster than the iWatch: it can predict biological age from select CpGs, which when compared with chronological age, gives a metric known as Δ-age. The greater the difference, the greater the acceleration of epigenetic age, which indicates variation in the rate of senescence between people. To understand this variation and […]
Stem Cell Scientists Use Cell Reprogramming Techniques to Study AgingOctober 22, 2015“Work harder, eat less, and, I’m begging you, get a haircut!” A face-to-face meeting between a younger and an older version of yourself would surely be filled with sage advice on how to live life and grow old gracefully. Many scientists wish to recreate such a meeting between young and old neurons to study aging and […]
Sorting the Old from the New – Cellular Barriers Keeps Stem Cells YoungSeptember 29, 2015Alongside smartphones, coffee shops, and bars, we all also need properly functioning stem cells to survive and prosper. Indeed, the stem cell theory of aging posits that the malfunctioning of stem cells in our later years, and not all that caffeine and alcohol, is the major cause of human aging. So how do we keep […]
Nukes Aid Stem Cell Research in the HeartJune 20, 2015Researchers from the laboratory of Jonas Frisén at the Karolinska Institutet in Sweden have recently put radioactive carbon from nuclear bomb tests to good use, testing whether the adult human heart has the ability to repair itself. So how does that work? Well, a sharp rise in atmospheric radioactive carbon in the 1950-60s due to […]
