Primitive. Simple. Advanced. Complex.
Scientists have developed a new approach for generating layered, difficult-to-combine, heterostructured solids (materials composed of layers of dissimilar building blocks), opening new avenues for electronic and energy applications. The technique for making them is simple, and counterintuitive — it involves smashing the pristine materials to build new ones. Smashing things together by milling seems like…

Primitive. Actions. Ecology. Pendulums.
Fossil data, historical records, and underwater survey data have been used to reconstruct the abundance of staghorn and elkhorn corals over the past 125,000 years. Researchers show that these corals first began declining in the 1950s and 1960s, earlier than previously thought. (1) Even the most primitive actions of people alter the planet. Even the…

Engraved symbols. Long gone. Deep into our heart…
Engraved stone artifacts are important clues to the history of human culture and cognition. Incisions on the cortex (soft outer layer) of flint or chert flakes are known from Middle and Lower Paleolithic sites across Europe and the Middle East. However, it can be difficult to determine the action that created an incision: was it…

Art. Caves. Sound. From silence…
When and where did humans develop language? To find out, look deep inside caves, suggests an MIT professor. More precisely, some specific features of cave art may provide clues about how our symbolic, multifaceted language capabilities evolved, according to a paper co-authored by MIT linguist Shigeru Miyagawa. A key to this idea is that cave…

Viking warriors… Women warriors…
Viking warriors have a historical reputation as tough guys, with an emphasis on testosterone. But scientists about a year ago said that DNA had unveiled a Viking warrior woman who was previously found in a roughly 1,000-year-old grave in Sweden. Until then, many researchers assumed that “she” was a “he” buried with a set of…
