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 […]
Brain training apps hold the promise that with just a few minutes a day of playing simple games, people can improve cognitive skills like memory. However, is that anything more than a promise? Most evidence on this topic is contradictory, with some studies reporting benefits and others no effects, but a recent real-word study published […]
Galaxy photos from Hubble feature merger, 3-armed spiral NASA has released the latest images captured by the Hubble Space Telescope since mission scientists repaired a major computer glitch that hobbled the spacecraft on June 13. The images, which haven’t been colourized, show the merger of a pair of galaxies and an unusual spiral galaxy with […]
Deoxyribonucleic acid (DNA) is the genetic material of most living organisms, being a major constituent of the chromosomes within the cell nucleus and playing a central role in the determination of hereditary characteristics by controlling protein synthesis in cells. DNA is, thus, a nucleic acid composed of two chains of nucleotides in which there is […]
One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anaesthesiologist Stuart Hameroff to propose an ambitious answer. They claimed that the brain’s neuronal system forms […]
