The holiday season is a time for giving thanks, giving gifts — and for many, a time for giving back.  Food banks, services that deliver meals to seniors and other U.S. charities typically see a surge in volunteering between Thanksgiving and the end of the year.  Alfred Del Grosso volunteers weekly to work the lunch shift at Shepherd’s Table, a food bank in Silver Spring, Maryland.

Why doing good also makes us feel good, during the holidays and beyond

Scientists may have "heard" the first tantalizing evidence of primordial black holes formed directly from overly dense pockets of matter just after the Big Bang.

Have gravitational waves provided the first hint of primordial black holes born during the Big Bang?

Depending on how you look at it, the universe might not have an "end," after all.

How will the universe end?

Archaeologists studied hundreds of unfinished stone heads in a quarry on Easter Island to better understand how they were constructed and the society that made them.

Easter Island quarry reveals how Polynesians made enigmatic stone statues

The mysteries of Easter Island, subjects of speculation for centuries, yield to scientific inquiry.

Drones, physics and rats: Studies show how the people of Rapa Nui made and moved the giant statues – and what caused the island’s deforestation

We have more neurons in our cortices than any other species, courtesy of an early technology – and along with them came our long, slow lives, with plenty of chances to gather around the dinner table.
