Phagocytosis Author: Marta Irigoyen is a postdoctoral researcher at CIC bioGUNE Phagocytosis of cancer cells by tumor-associated macrophages (TAMs), which are abundant in the tumor microenvironment (TME), plays a critical role in cancer immunosurveillance . Cancer cells can evade macrophage-mediated phagocytosis (the process by which a cell uses its plasma membrane to engulf particles or […]
early galaxy problem Author: Rajendra Gupta, Adjunct professor, Physics, L’Université d’Ottawa/University of Ottawa Early universe observations by the James Webb Space Telescope (JWST) cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, based on the big-bang expanding universe concept. My research proposes a model that […]
Cell division, or mitosis, is a breathtaking choreography that showcases the grandeur of life. The primary objective of this process is to meticulously separate the two copies of the cell genome, presented in the form of chromatin, and allocate them between two daughter cells. Consequently, it holds paramount significance for the reproduction of unicellular organisms […]
Purple bronze Scientists have discovered a rare phenomenon that could hold the key to creating a ‘perfect switch’ in quantum devices which flips between being an insulator and superconductor. The research found these two opposing electronic states exist within lithium molybdenum purple bronze, a unique one-dimensional metal composed of individual conducting chains of atoms. Tiny […]
words Author: Juan F. Trillo, PhD in Linguistics and Philosophy (U. Autónoma de Madrid), PhD in Literary Studies (U. Complutense de Madrid). The first word of the Preamble to the Constitution of the United States is “ We “, a personal pronoun belonging to the category of function words and, as such, ambiguous, which is […]
Chemical contamination of water bodies on one hand, and water shortages due to overexploitation on the other, have increased the need for effective and efficient water treatment and decontamination processes. Two important aspects need to be taken into consideration to define what is an “effective and efficient” treatment. First, as current methods of removing pathogens […]
In the largest survey of its kind ever conducted researchers from the University of Copenhagen firmly established a fivefold increase in the melting of Greenland ‘s glaciers over the last 20 years. Using both satellite imagery and old aerial photos from the Danish National Archives, researchers from the University of Copenhagen firmly establish that Greenland’s […]
Platelets 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. There is currently a […]
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 […]
