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 – […]
Over the past several decades researchers have thought how materials and device architectures can efficiently convert solar radiation into electrical power through the photovoltaic effect. Those efforts have led to different methods and processes to produce green energy. In this context, organic photovoltaic (OPV) technology has received considerable attention because it indeed constitutes a new […]
In early 2021, just after the Perseverance Rover landed on Mars, a purported image of the Martian night sky went viral. In that image, above the sleek metal of a Mars rover, the clearly defined Milky Way cuts from horizon to horizon, crossing a sky filled with so many stars that there is no darkness […]
