T-cell acute lymphoblastic leukemia (T-ALL) is characterized by the accumulation of genetic lesions that induce differentiation arrest, survival and aberrant proliferation of immature T-cell progenitors . Although T-ALL prognosis has significantly improved due to intensive chemotherapy, relapses still occur in 20% of pediatric patients and 50% of adult patients, often with a dismal outcome. To […]
Authors: David Sidhu, Assistant Professor, Department of Psychology, Carleton University and Penny Pexman, Professor of Psychology, Western University Imagine you’re hiring someone for a job that requires a very kind, agreeable and co-operative person. You have two candidates and all you know about them are their names: Renee and Greta. Who do you think would […]
The Earth supports the only known life in the universe, all of it depending heavily on the presence of liquid water to facilitate chemical reactions. While single-celled life has existed almost as long as Earth itself, it took roughly three billion years for multicellular life to form. Human life has existed for less than one-10 […]
When you look at a crystal—say, a piece of salt or a sheet of graphene—its atoms are not randomly scattered. They form an orderly grid, like tiles on a floor. Because the atoms are arranged in this repeating way, electrons moving through the crystal don’t behave as if they’re in free space. Instead, their motion […]

Author: Sevrine Sailley, Senior Scientist, Marine Ecosystem Modelling, Plymouth Marine Laboratory Climate change is reshaping fish habitats. Some fish are winners, others are losing out. Fish already face plenty of pressure from overfishing and pollution. Climate change is adding more: warmer waters and shifting food supplies cause what’s known as a predator-prey mismatch. This means […]
We’re often told it is “unscientific” or “meaningless” to ask what happened before the Big Bang. But a new paper by cosmologist Eugene Lim, of King’s College London, UK, and astrophysicists Katy Clough, of Queen Mary University of London, UK, and Josu Aurrekoetxea, at Oxford University, UK, proposes a way forward: using complex computer simulations […]
Authors: Lieke A. Heijmans is an undergraduate student at the Linguistics program of the University of Groningen, The Netherlands. Adrià Rofes is associate professor in Neurolinguistics at the University of Groningen, The Netherlands. Losing the ability to speak doesn’t always mean losing the ability to communicate. For many people living with aphasia (i.e., a language […]
In physics, waves often reveal more than meets the eye. A ripple on a pond looks simple enough, but beneath its surface lies a rich mathematical structure that can connect something as everyday as water to the abstract worlds of optics, acoustics, and even quantum mechanics. A recent work brings this connection vividly to life […]
A team of scientists has discovered a new type of crystal that can “breathe”—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices. The newly developed material is a special kind of metal oxide made […]
If you’re reading this, you’ve probably taken a calculus course before. How was it? Chances are you found it frustrating or, at least, complicated. You may remember one of the most feared parts of calculus courses: the computation of derivatives and integrals. For most students, this is the first time they face a mathematical problem […]
