A 5,500-year-old tomb possibly belonging to a Stone Age chieftain has been unearthed at a megalithic monument in the shape of a ship called the Ale’s Stenar (Ale’s Stones). The tomb, in Sweden, was likely robbed of stones to build the Viking-era ship monument. “We found traces — mostly imprints — of large boulders,” said…

In this material universe, they amount to just about nothing at all. And yet … it would be hard to make a case that any other group of elements has had a greater impact on our understanding of the universe.
Getting a six-wheeled car-size rover safely onto the surface of the red planet? Daunting, sure. But NASA did it with Curiosity. Sending humans on a mission to Mars? That requires overcoming even more outlandish obstacles. Here’s a look at five of the top challenges to safely getting astronauts to Mars, as well as potential solutions….
It is in our nature to fit nature to us. We are best at it, but other species do it. This obvious but overlooked factor contradicts the dominant one-way-street gene-centric view of adaptation. A better framework for evolution is needed. Its shape isn’t clear, but it must incorporate: extracorporeal gene effects, “gene-culture coevolution,” “niche construction,”…
More than half of our nation’s waterways are in “poor condition.” So said the “National Rivers and Streams Assessment”, a recent report from the EnvironmentalProtection Agency (EPA). As the weather warms and minds turn to spring and summer recreation, waterways in poor condition affect you directly if you are planning to swim, fish, or boat…
