This hearth from one of the Mesoamerican smelting furnaces, seen as it was being excavated by Dorothy Hosler and her team in Mexico, was among the sites that revealed that indigenous people were producing copper for the Spanish colonists.

Mesoamerican copper smelting technology aided colonial weaponry

Spanish conquerors depended on indigenous expertise to keep up their munitions supplies, archaeologists have found.

An iterative, multi-step process for training a neural network, as depicted at top left, leads to an assessment of the tradeoffs between two competing qualities, as depicted in graph at center. The blue line represents a so-called Pareto front, defining the cases beyond which the materials selection cannot be further improved. This makes it possible to identify specific categories of promising new...

Researchers confirmed the existence of electronic waves that are frozen at a transition temperature of 125 kelvins and start “dancing together” in a collective oscillating motion as the temperature is lowered. In this illustration, a red laser beam triggers the dance of the newly discovered electronic waves in magnetite.

Dancing electrons solve a longstanding puzzle in the oldest magnetic material

Physicists use extreme infrared laser pulses to reveal frozen electron waves in magnetite.

An MIT team found a way to “recruit” normally disruptive quantum bits (qubits) in diamond to, instead, help carry out quantum operations. This approach could be used to help scale up quantum computing systems.

Novel method for easier scaling of quantum devices

System “recruits” defects that usually cause disruptions, using them to instead carry out quantum operations.

Beams of circularly polarized light (shown as blue spirals) can have two different mirror-image orientations, as shown here. When these beams strike a sheet of titanium diselenide (shown as a lattice of blue and silver balls), the electrons (aqua dots) in the material take on the handedness of the light's polarization.

Researchers found that strontium cobalt oxide (SCO) naturally occurs in an atomic configuration called brownmillerite (center), but when oxygen ions are added to it (right), it becomes more orderly and more heat conductive, and when hydrogen ions are added (left) it becomes less orderly and less heat conductive.

A material’s insulating properties can be tuned at will

Most materials have a fixed ability to conduct heat, but applying voltage to this thin film changes its thermal properties drastically.
