Neandertals traveled at least two evolutionary paths on their way to extinction around 40,000 years ago, a new study suggests.
Whether classified as a separate species or a variant of Homo sapiens, Neandertals have typically been…

Mathematical proof: Five satellites needed for precise navigation
As a rule, GPS indicates our location with an accuracy of just a few meters. But we have all experienced situations where the possible error increases to a few hundred meters or the indicated location is simply wrong. One reason for this can be…

Mathematicians model a puzzling breakdown in cooperative behavior
Darwin was puzzled by cooperation in nature — it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game theory to better understand why mutual…

How cheerful is that water bottle?
New research from the University of Georgia Terry College of Business shows consumers use “happier” words to search for products when they are in a good mood. Researchers have connected those positive search terms with an increased likelihood of…

Despite new clues, this ancient fish has stumped scientists for centuries
It wasn’t an ancient boomerang. It was, in fact, a fish — albeit unlike any known today. Beyond that, nobody’s quite sure what to make of Pegasus volans.
The fish’s ribbonlike body, known from two fossils from a…

New Circuit Made of DNA Has Everything Wired In – Chemistry | Weizmann Wonder Wander
Weizmann Institute of Science researchers were thrilled when they managed to observe the birth of a protein made by a single DNA molecule: No one had previously seen this event outside a cell. That excitement, however, was only the beginning. The…

Earthquake-Induced Piezoelectricity Plays Key Role in Formation of Large Gold Nuggets: Study
Gold nuggets occur predominantly in quartz veins, and the current paradigm posits that gold precipitates from hot water and carbon dioxide-rich fluids owing to changes in temperature, pressure and/or fluid chemistry. However, the widespread…
