Scientists Show Transmission of Epigenetic Memory Across Multiple Generations

A new research study reveals how a common type of epigenetic modification can be transmitted via sperm not only from parents to offspring, but to the next generation (“grandoffspring”) as well. Changing the epigenetic marks on chromosomes results in altered gene expression in offspring and in grandoffspring, demonstrating ‘transgenerational epigenetic inheritance.’ Without changing the genetic …

Supercomputer Simulations Just Gave Us a New Explanation for How the Moon Was Created – IGN

The Moon may have formed almost immediately following a devastating impact between Earth and a Mars-sized world in the ancient past, according to the results of a new supercomputer study. Earth’s moon is a silent witness to the history of our entire species. Its gravitational influence is responsible for the tides, and its simple presence …

Discovery Alert: A Rocky 'Super-Earth' in the Habitable Zone

Discovery Alert: A Rocky ‘Super-Earth’ in the Habitable Zone

The discoveries: LP 890-9 c, a “super-Earth” in the habitable zone of its star. Key facts: The planet, likely rocky but 40% larger than Earth, came to light during follow-up observations of its sister planet, LP 890-9 b. Both fall into the super-Earth category – exoplanets, or planets around other stars, that are up to …
