Atomic nuclei take a range of shapes, from spherical (like a basketball) to deformed (like an American football). Spherical nuclei are often described by the motion of a small fraction of the protons and neutrons, while deformed nuclei tend to rotate as a collective whole. A third kind of motion has been proposed since the […]
Intermittent fasting, that is, eating only over a certain time period during the day, can have positive mental health effects, at least according to a recent study . Intermittent fasting for 16 hours a day, that is a 16:8 fasting paradigm, for five days a week during three months improved quality of life while decreasing […]
Ancient fish that ate humans’ ancestors discovered Researchers have excavated the remains of a giant ancient bony fish species with fangs from about 350 million years ago in what is now South Africa. The findings, published in the journal PLOS One, indicate that the Hyneria udlezinye species measured up to 2.7 meters long and likely […]
As candidates for high-density data storage and quantum computation, magnetic transition metal complexes have attracted extensive attention. It has been established that the atomic surroundings of the magnetic ions play a significant role and govern the magnetism of these magnetic complexes. One feature in particular, magnetic anisotropy, which describes the preferential orientation of the magnetic […]
Author: Juan F. Trillo, PhD in Linguistics and Philosophy (U. Autónoma de Madrid), PhD in Literary Studies (U. Complutense de Madrid). This essay is an excerpt from the paper that will be presented at the IX Jornadas de Divulgación Científica at the city of Medellín, Badajoz (Spain), March 2-5, 2023. The possibility of establishing contact […]
Gas clouds in the Cygnus X Region, a region where stars form, are composed of a dense core of molecular hydrogen (H2) and an atomic shell. These ensembles of clouds interact with each other dynamically in order to quickly form new stars. The Cygnus X region is a vast luminous cloud of gas and dust […]
In 1868, the famous, powerful and short French neurologist Jean-Martin Charcot, known as “the Napoleon of the Salpêtrière hospital”, described a new disease. He called it “sclerose en plaque” in reference to the numerous scars or sclerosis seen in the white matter of the brain and spinal cord. We now call it multiple sclerosis. Multiple […]
Analysis of cell villages yields insight into Zika infections Studying cell villages, or samples from different donors in a shared environment, is an effective method “to identify genes and genetic variants that change a cell’s phenotype.” Scientists used the method along with the Dropulation and Census-seq algorithms to assess genetic variation in cell villages and […]
Mermin–Wagner The demand for computational power is increasing exponentially, following the amount of data generated across different devices, applications and cloud platforms. To keep up with this trend, smaller and increasingly energy-efficient devices must be developed, which require the study of compounds not yet explored in data-storage technologies. The discovery of magnetically stable 2D van […]
Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. Hummingbirds are fascinating animals. They are the only birds able to true hovering and backward flight. This ability allows them to collect nectar […]
