Origin firing is the initiation of DNA replication that takes place at specialised start sites, or replication origins, where the DNA first has to be opened up and unwound, before DNA synthesis ...

[Editors' note: this paper was reviewed by Review Commons.] Cancer cells display high levels of oncogene-induced replication stress (RS) and rely on DNA damage checkpoint for viability. This feature ...

As a result, says Aditi Nerurkar, a lecturer at Harvard University and author of The 5 Resets: Rewire Your Brain and Body for Less Stress and More Resilience, around 96 percent of us are facing at ...

Your emotions can indicate when you’re under too much stress. For example, feeling irritable or overwhelmingly fearful can be signs of stress. Stress, defined as emotional tension or mental ...

Scientists at deCODE genetics have unveiled a groundbreaking map of human DNA mixing during reproduction, offering insights into genetic diversity, health, and fertility. Credit: SciTechDaily.com ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...

We all know stress messes with our heads, but did you know it can also wreak havoc on our bodies? Say hello to cortisol, the hormone released when stress hits, triggering that familiar “fight ...

Researchers have observed that social stress increases markers of DNA damage in the brain. This damage can lead to mutations and errors in DNA replication, thus contributing to accelerated aging and ...

The goal: to de-stress. The Bhagavad Gita, a Hindu scripture from 1st or 2nd century BC, talks about “pranayama”—a yoga practice of controlling the breath—and yoga texts from a few ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.
