Study shows epigenetic memory can be passed on across multiple generations

To summarize: By altering epigenetic marks on chromosomes, researchers witnessed changes in gene expression in offspring and grandchildren. The findings reveal the occurrence of epigenetic inheritance across representations. resource: UC Santa Cruz Without changing the genetic code in DNA, epigenetic modifications can alter how genes are expressed, affecting the health and development of an organism. …

The core principle of general relativity just passed its toughest test yet

A core principle of Einstein’s general theory of relativity has just passed its most rigorous test yet. Using specially designed satellites, an international team of scientists measured the acceleration of pairs of free-falling objects in Earth orbit.Results based on five months of data show that the difference in acceleration is no more than a tenth …

Einstein’s general theory of relativity just passed its toughest test yet

Scientists have shown that Einstein’s general theory of relativity is correct with astonishing accuracy, even though it has been around for more than a century. The team behind the study wants to test Einstein’s General Theory of Relativity Known as the weak equivalence principle, this principle states that all objects, regardless of their mass or …
