Have you ever wondered what chickens are talking about? Chickens are quite the communicators — their clucks, squawks and purrs are not just random sounds but a complex language system. These sounds are their way of interacting with the world and expressing joy, fear and social cues to one another. Like humans, the “language” of […]
Ernest Lawrence was awarded the Nobel Prize in Physics in November 1939 “for the invention and development of the cyclotron and for results obtained with it, especially with regard to artificial radioactive elements”. His invention was based on generating a spiral accelerated trajectory of protons governed by a simple alternating radio frequency voltage together with […]
Acute myeloid leukemia (AML) is the most common acute leukemia in adults and a common pediatric cancer. Most often, AML develops from cells that would turn into white blood cells. AML is divided into different subtypes based on the cell type and maturation stage. Currently, monocytic AML, including acute myelomonocytic leukemia (M4) and acute monocytic […]
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. On October 11th, I published an article on Mapping Ignorance about the microbial dark matter, the vast diversity of microorganisms that cannot be […]

“Censorship” is not a pleasant word to anyone. Its connotations are almost always negative and, in the first instance, an effort should be made to find circumstances that justify a restriction of information. Even more so in the scientific field, where empirical evidence should prevail over authority, tradition, rhetorical eloquence or social prestige. Science seeks […]
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. Solid cancerous tumor is a […]
T-cell acute lymphoblastic leukemia (T-ALL) is a hematological malignancy that affects both children and adults. Although with current chemotherapy regimens cure is achieved in ~80% of pediatric patients, adults fare more poorly with only 40% 5-year overall survival . Restricted cellular subsets with asymmetrically enriched leukemia-initiating cell (LIC) activity have been reported in human and […]
Humanity’s emissions of greenhouse gases have caused rapid global warming at a rate unprecedented in at least the past 2,000 years. Rapid global warming has been accompanied by increases in the frequency and intensity of heat extremes over most land regions in the past 70 years. While human activities cause emissions of a number of […]
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 […]
