The scattering of conduction electrons in metals owing to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has the consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered and […]
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. All the cells in our body require a supply of oxygen, although in some cases, they can temporarily rely on anaerobic metabolism. Under […]
Evaporation is happening all around us all the time, from the sweat cooling our bodies to the dew burning off in the morning sun. But science’s understanding of this ubiquitous process may have been missing a piece all this time. In recent years, some researchers have been puzzled upon finding that water in their experiments […]
Cutaneous Author: Marta Irigoyen is a postdoctoral researcher at CIC bioGUNE Cutaneous T-cell lymphoma (CTCL) is a rare type of cancer that begins in white blood cells called T cells (T lymphocytes). These cells normally help the body’s immune system to fight germs and pathogens. In cutaneous T-cell lymphoma, T cells acquire aberrant functions that […]
Jupiter-like planets push Earth-sized planets aside Jupiter-sized gas giant planets can cause chaos in young planetary systems, moving smaller planets out of their orbit and impacting the habitability of those planets. While Jupiter’s gravitational field acts as a shield for Earth, it would harm Earth’s climate if it were located in the middle of our […]
nanocolloids The increasing attention to the design and experimental development of self-oscillating matter is primarily motivated by the potential use of such systems in emerging technologies (e.g., light engines) comprising compact components and minimum energy consumption. Self-oscillation is the generation of a periodic change in a system fuelled by a steady, non-periodic power source. The […]
collision Authors: Simon Lock, NERC Research Fellow, School of Earth Sciences, University of Bristol; Matthew Kenworthy, Associate professor in Astronomy, Leiden University, and Zoe Leinhardt, Associate Professor, School of Physics, University of Bristol The afterglow of a massive collision between two giant planets may have been detected for the first time. The wreckage of the […]
Polyfluoroalkyl substances (PFAS), a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) appear to cause organ damage and cancer, as well as disrupting the endocrine system. Researchers have now introduced a new method for an […]
Lipids represent one of the fundamental molecular components within the realm of biological organisms, alongside proteins, carbohydrates, and nucleic acids. The concept of the “lipidome” pertains to the entirety of lipids found within a cell or a collection of cells. This terminology emerged within the context of modern biological sciences, often referred to as “omic […]
Female chimpanzees go through menopause Some female chimpanzees experience menopause similar to humans, according to a study of wild chimpanzees in Uganda’s Kibale National Park. Researchers analyzed urine samples from 66 female chimps and found that their hormone levels shifted around age 50 similarly to women in middle age and calculated that the female animals […]
