“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 […]

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 […]
