T-cell acute lymphoblastic leukemia (T-ALL) is a devastating disease of T-cell progenitors that mainly affects children and young adults. Numerous genomic alterations are known to induce survival, proliferation, and differentiation of T-ALL cells . The interactions between leukemic cells and their microenvironment are known factors that contribute to T-ALL pathogenesis. The bone marrow (BM) microenvironment […]
It has been known for a while that pregnancy changes the brain. We had available data for humans and other mammals showing that after becoming mothers, women’s brains had undergone such profound changes that it is sometimes compared to the reorganization the brain suffers during puberty. What’s new then? A recent study put a scientist […]
Scientists seeking better methods for controlling the quantum interactions between light and matter demonstrated a novel way to use light to give electrons a spinning kick. The results of their experiment show that a light beam can reliably transfer orbital angular momentum to itinerant electrons in graphene. Having tight control over the way that light […]
A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron beam and an ultrahigh intensity laser pulse using the 4-Petawatt laser at the Center for Relativistic Laser Science (CoReLS) within the Institute for Basic Science at Gwangju Institute of Science and Technology (GIST), Korea. The innovation is the use of […]
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. Alzheimer’s disease (AD) is a […]
In certain materials, when we apply an electric field (it could be that of light) that vibrates at a certain frequency, it can create a direct current, a steady flow of electrical charge. This current is special because its strength depends on the square of the electric field’s strength. This phenomenon is called “shift current.” […]
Odi et amo. I hate and I love. Maybe you’re wondering why I do that. I do not know. But I feel it happening, and I suffer. So Catullus, famous ancient Roman poet, described the painful and puzzling feeling of love’s contradiction. And if you have ever experienced heartbreak, it’s very likely that you understand […]
Numerous proteins in the cell withstand mechanical loads while performing their function. This is especially significant for cell-surface proteins located in the extracellular matrix, which are essential for the communication between cells in the extracellular milieu. Reacting to mechanical force through conformational changes is crucial for these cell-surface proteins, translating a physical signal into an […]
Authors: Albert HiuKa Fok, Postdoctoral Fellow in Neuroscience, McGill University and Sabrina Chierzi, Research Associate, Neuroscience, McGill University Astrocytes — named for their star-like shape — are a type of brain cell as abundant as neurons in the central nervous system, but little is known about their role in brain health and disease. Many neurological […]
Scientists believe individuals of the most recently discovered hominin group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history. In 2010, the first draft of the Neanderthal genome was published, and comparisons with modern human genomes revealed that Neanderthal […]
