Do telomere length tests really reveal your biological age?
Curiosity about how well our bodies are ageing has fuelled an industry around telomere length tests, but the much touted “biological clock” in our DNA isn’t what we thought Source: https://www.newscientist.com/article/mg24933221-000-do-telomere-length-tests-really-reveal-your-biological-age/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Supercomputer turns back cosmic clock
Astronomers have tested a method for reconstructing the state of the early universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with new observations, the method can set better constraints on inflation, one of the most enigmatic events in the history of the universe. The…

Researchers rewind the clock to calculate age and site of supernova blast
Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA’s Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of the location and time of the stellar detonation.
