NASA has been on a roll but aiming for even bigger wins

Even for an agency that put the first human on the moon, designed and flew the first reusable spacecraft and has extended our land-based and extraterrestrial space exploration tools, and subsequent knowledge of the universe, in myriad ways, NASA has put together a pretty solid winning streak recently. On Monday evening, the world had a …

Sagittarius Galaxy

Scientists Detect a Neighboring Galaxy Filled With Dark Matter

By Kavli Institute for the Physics and Mathematics of the Universe September 27, 2022 A small satellite galaxy (green globe on the bottom left) of the Milky Way – called Sagittarius – has been observed from Earth through giant lobes of gamma radiation (aka the Fermi bubbles, purple areas below and above the galaxy). Although …

Researchers reconstruct the genome of the common ancestor of all mammals

An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like this fossil animal, Morganucodon, which lived about 200 million years ago. Credit: Wikipedia by …

As Hurricane Ian closes in, NASA weighs options for Artemis 1 moon rocket launch

As Hurricane Ian closes in, NASA weighs options for Artemis 1 moon rocket launch

There is only a slight chance that NASA’s moon mission will launch in the next month. The agency’s Artemis 1 stack, including the Space Launch System (SLS) megarocket, rolled back to shelter earlier today (Sept. 27) ahead of a hurricane that may send winds at its Florida launch site gusting at up to 130 mph …

Study Shows Transmission of Epigenetic Memory Across Multiple Generations – Neuroscience News

Summary: By altering the epigenetic markers on chromosomes, researchers witnessed changed gene expression in offspring and grand-offspring. The findings reveal the occurrence of transgenerational epigenetic inheritance. Source: UC Santa Cruz Without altering the genetic code in the DNA, epigenetic modifications can change how genes are expressed, affecting an organism’s health and development. The once radical …
