Epigenetic Two-factor Authentication Secures Male Fertility from the Insider Threat of TransposonsOctober 7, 2024Two-factor authentication represents a modern approach to securing our digital lives from outside threats; however, research now suggests that this concept may not be so modern. A new study now reveals that male germ cells employ a piRNA-mediated epigenetic “two-factor authentication” strategy to secure the precisely timed DNA methylation-induced silencing of insider threats that impact […]
Metformin Keeps Aging Primate Epigenomes “In Form”September 30, 2024Those of us feeling the all too familiar effects of time may look to cut back on certain “excesses” and keep fit (in both body and mind) to maintain a healthy aging process. Now, a team of fitness enthusiasts has revealed that long-term treatment with the diabetes drug metformin maintains an aging population of monkeys […]
Amyloids Could Solve the ‘Missing Heritability’ MysterySeptember 23, 2024Science is full of mysteries just waiting to be solved. One of these mysteries is the “missing heritability” problem—it turns out that some traits seem hereditary, yet cannot be traced back to nucleic acids or even known epigenetic modifications. Now, a talented team studying C. elegans has spotted protein clumps called amyloids that could be […]
Genome-Wide DNA Methylation Changes from Vaping and Smoking Have Striking SimilaritiesSeptember 3, 2024Vaping has been touted as a safer alternative to smoking, but some recent studies are showing that the biological effects have similarities. Now, a team clears the air and reports that DNA methylation changes in vapers’ oral cells resemble those found in smokers, which suggests that vaping could have comparable long-term health effects. Smoke gets in […]
Epigenetic Machinery Fights Back! SARS-CoV-2 RNA Modifications Inhibit Replication and PathogenesisSeptember 3, 2024Recent reports have highlighted how SARS-CoV-2 infection and the resulting COVID-19 can turn epigenetics against us; however, new research now reveals that the epigenetic machinery can also help us fight back against viral attacks – in the guise of specific RNA modifications. A team of epigenetic tusslers guided by Yu Chen (Wuhan University) knew of […]
