Astronomers Believe Type Ia Supernovae Can Explain Why the Universe is Expanding Faster Than Predicted
Here's a great writeup on this week's big Astronomy news, and why it's important.
It also illustrates the challenges astronomers face with respect to ever-increasing demands for radio spectrum.

Shut up and simulate. (In which I try to understand how dark matter forms galaxies, and end up very confused.)

"Genetics and epigenetics are two types of studies of genes. The main difference between genetics and epigenetics is that genetics is the study of genes that control the functions of the body whereas epigenetics is the study of inheritable changes of the organisms caused by the modification of gene expression."

"There are two important, longstanding, and related questions about the hot solar wind: how is it heated, and how does the corona produce the wind? Astronomers suspect that magnetic reconnection in the chromosphere plays a key role."
