Twistology could be the study of unexpected changes or developments in stories or situations, from coups d’état to the fatherhood of Darth Vader. In condensed matter physics there is something similar, although the preferred name is twistronics (from twist and electronics). It is understood as the study of how the angle (the twist) between layers […]
During the pandemic, the pejorative term “snake-oil salesman” has been bandied about a lot. It’s been used, perhaps with a tinge of 1980s nostalgia, to describe convicted fraudster and serial opportunist Jim Bakker, whose colloidal Silver Solution required only some deft rebranding to become a specific curative for COVID-19. For this, the televangelist found himself […]
If we look back at our past, we are all aware of how much we have changed. The innocence of our childhood, the impulses of our adolescence, the vehemence and passion of our youth, the tranquillity of our mature life: some of us already know what we will be like when we grow up! Hopefully […]
Smoke from wildfires may block clouds’ rainmaking ability Water droplets are more abundant in clouds affected by wildfire smoke but, surprisingly, those clouds are less likely to produce rain and may contribute to drought conditions in the Western US. Scientists say the droplets inside the affected cumulus clouds are much smaller and less likely to […]
Aromaticity is a property of cyclic (ring-shaped), planar (flat) structures with π bonds in resonance (those containing delocalized electrons) that gives increased stability compared to other geometric or connective arrangements with the same set of atoms. Aromatic rings are very stable and do not break apart easily. An aromatic ring contains a set of covalently […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. A long time ago, I […]
In a paper led by Passaro and coworkers we sought to identify a functional link between the activity of a protein called calcineurin and the response of a type of leukemic cells known as “T-ALL” to microenvironmental signals. Furthermore, we wanted to determine whether interrupting these signals could affect to leukemia development, thus providing alternative […]
Early Homo groups once trekked to a well-watered Arabia The Arabian Peninsula was once a green oasis that attracted ancient Homo groups as early as 400,000 years ago during wet periods. Researchers have found evidence of animals migrating to the area’s lakes, rivers and wetlands as well as stone tools. Science News Amputees feel sensations […]
Since the discovery of graphene, a wide diversity of atomic-layer-thick, two-dimensional (2D) materials with varied properties have emerged. Of particular interest are those that exhibit semiconducting behaviour, such as hexagonal boron nitride (hBN). hBN is isoelectronic to graphene and has also a honeycomb lattice formed by alternating nitrogen and boron atoms, but in contrast to […]
They were not killed by delinquents who’d had a life of trauma, nor by sadists sunk in the abysses of sex. Their executioners were not barbarians inhabited by notions of genocides, nor slaves to sects that annul reason. They were not killed by the madness that cities sometimes engender. The horror was the handiwork – […]
