Social networks and digital platforms allow adolescents to interact with each other and to develop and maintain positive interpersonal relationships and support networks that are critical in their development. In general, teens benefit from socialization opportunities such as keeping in touch, sharing images, or interchanging ideas. In addition, social networking encourages participation, creative expression, and […]
Carbon monoxide (CO) oxidation (CO + ½ O2 → CO2) is an industrially relevant catalytic reaction, and accordingly, it is among the most studied processes in fundamental surface science. This has led to a wealth of research studies in vacuum, but the doubts remain on whether this reaction proceeds in the same way when changing […]
Blazars draw power from black holes High-energy particles such as neutrinos and cosmic rays that pummel the Earth from the depths of space originate in actively galactic nuclei fueled by giant black holes, known as blazars. “The discovery of the connection between these objects and the cosmic rays may be the ‘Rosetta stone’ of high-energy […]
When the surface of a perfect conductor is structured at a length scale much smaller than the operating wavelength, geometrically induced surface electromagnetic modes can be supported. Owing to their similarities with the surface plasmon polaritons in the optical regime, these surface electromagnetic modes were named spoof surface plasmons. A new review provides a detailed […]
Modelling of neuron-glial interactions is an emerging field of Computational Neuroscience. The ubiquity of these interactions and the possibility that they may occur within the time and spatial scales that are usually ascribed to neuronal and synaptic function, calls for a revision of current neuron-based modeling paradigms to include potentially relevant effects mediated by glial […]
New research has unearthed evidence that points to a strong relationship between the magnitude of mass extinctions and global temperature changes in geologic times. Abrupt climate change, accompanied by environmental destruction from large volcanic eruptions and meteorites, has caused major mass extinctions throughout the Phanerozoic Eon, covering 539 million years to the present. To date […]
Mammals became warm-blooded around 233M years ago Warm-blooded mammals evolved roughly 233 million years ago, nearly 20 million years later than previously believed, after studying tiny inner ear canals that carry a viscous fluid called endolymph, which flows more easily when warmed and requires smaller passageways. The study looked at the inner ear canals of […]
Graphene is an exceptional material with attractive properties to explore fundamental physics and for use in technological applications. While ideal graphene is non-magnetic, custom-shaped graphene nanostructures can be designed to exhibit complex magnetic phenomenology, with promising possibilities for a new generation of nanoscale spintronics devices. In fact, graphene π magnetism is more delocalized and isotropic […]
Every geography schoolbook has them: maps that look like today’s Earth, but not quite, since all continents are merged into a single supercontinent. Those maps were used to explain why dinosaurs in South America and Africa, or North America and Europe looked so alike. “Paleogeographic” reconstructions like these provide context to study the processes that […]
A common saying refers to the power of the eyes as a window inside our souls; interestingly, our eyes could also be a window into our brains, helping identify certain neurological conditions like attention deficit hyperactivity disorder (ADHD) or autism spectrum disorder (ASD). Recent work published in Frontiers in Neuroscience found distinct electrical recording signatures […]
