Giant wooden marker post dates Cahokia's political and economic peak
Dr. Nicholas Kessler and his colleagues examined the largest known marker post from the ancient North American city of Cahokia. Their study is published in PLOS One.
Exploring how dark matter alters electron-capture supernovae and the birth of neutron stars
Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are ...
Graphene partially screens van der Waals interactions depending on layer thickness, study reveals
Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk materials. Some recent studies ...
Repetitive negative thinking mediates relationship between self-esteem and burnout in students, study finds
When people are highly stressed for prolonged periods of time, they can sometimes experience a state known as burnout, characterized by pronounced emotional, mental and physical exhaustion. The stressors leading to burnout ...
High-fidelity entangling gates connect remote superconducting quantum processors
Quantum computers hold the potential of solving some optimization and data processing problems that cannot be tackled by classical computers. Many of the most promising quantum computing platforms developed so far are based ...
A new perspective on how cosmological correlations change based on kinematic parameters
To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships between different events or fields in spacetime, broadly referred to as cosmological correlations. ...
Measuring a previously mysterious imaginary component of wave scattering
There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, outgoing light wave. In particular, the time delay of the transition from one to the other comes out ...
Ibex motif linked to fertility and celestial symbolism in ancient Near East art
In a new study published in L'Antropologie, Dr. Shirin Torkamandi and his colleagues, Dr. Marcel Otte and Dr. Abbas Motarjem have analyzed the symbolic meaning of bovidea, particularly the ibex, in the ancient Near East.
Mystery Greek hominin skull dated to be at least 286,000 years old
Research led by Institut de Paléontologie Humaine is providing a finite minimum age for a nearly complete cranium from Petralona Cave in Greece that has perplexed researchers since its discovery in 1960.
Single quantum device that measures amperes, volts and ohms could revolutionize how we measure electricity
A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm ...
