Students who feel connected to their peers and teachers are more inclined to alert a teacher or principal if they hear a fellow student "wants to do something dangerous," according to a new study published by the American Psychological Association.
In an unusual intersection of materials science and anthropology, researchers from the National Institute of Standards and Technology (NIST) and The George Washington University (GWU) have applied materials-science-based mathematical models to help shed light on the dietary habits of some of mankindâ€™s prehistoric relatives.
Our surnames and genetic information are often strongly connected, according to a study funded by the Wellcome Trust. The research, published this week in the journal Molecular Biology and Evolution, may help genealogists create more accurate family trees even when records are missing.
New research helps us understand the incredible forces and oil and gas reserves that lie hidden beneath the Earthâ€™s surface.
New research provides strong support for the idea that one of the key functions of sleep is the consolidation of memories.

- The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
