An atomic force microscopy scan of a nanometer-sized device developed by Carnegie Mellon scientists that demonstrates a new form of the Hall effect. For more than a century, the Hall effect has been taught with a simple picture that electricity flows through a material, a magnetic field pushes the moving charges sideways, and a voltage … Read more

Archeologists discovered 7,000-year-old Neolithic burial grounds in France using electrical surveys

Coëby contains numerous megalithic monuments. Image Credit: Wikimedia commons Archaeologists investigating a Neolithic cemetery in Brittany, France, may have uncovered clues to a burial tradition that dates back around 7,000 years. At the Coëby Neolithic cemetery near Trédion, researchers examined two unusually large, elongated earth mounds whose purpose has remained uncertain since the site was … Read more
