A new book lets the Milky Way speak for itself — and it's kind of a jerk

A new book, "The Milky Way: An Autobiography of our Galaxy," by astrophysicist Moiya McTier, imagines our galaxy using its own voice to spill the beans on topics like how it came to be, what it really thinks of us humans, its complicated relationships with other galaxies — and how it will likely meet its demise.

Walking 10K steps a day is a health sweet spot, study finds — and walking faster is even better

In recent years, walking 10,000 steps a day has become a popular fitness goal, but until now, there hasn’t been much scientific research to back that number. A new study looking at people wearing fitness trackers has finally determined that it is indeed a sweet spot for a range of health outcomes, but how fast you walk is also important.

For many of us, summer is the time for things like beaches, bike rides, and BBQs. For some scientists, however, summertime is also when they are at their busiest, travelling to remote locations to get up close and personal with nature.

Artemis SLS rocket has taken years longer to develop than the Apollo moon program

Bob McDonald's blog: NASA's giant rocket program, plagued by delays and cost overruns, may finally launch, just as a private competitor might be ready to do it faster and cheaper. But does what looks like a boondoggle have hidden value?
