By Invited Researcher

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 […]

By Mapping Ignorance

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 […]

Selective reduction and its reversibility: a crystal that <i>breathes</i> oxygen

Selective reduction and its reversibility: a crystal that breathes oxygen

ChemistryEnergyMaterialsPhysics

By Mapping Ignorance

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 […]

By DIPC

Positron Emission Tomography, or PET, is one of medicine’s most powerful tools for looking inside the human body, revealing not only anatomy but also how tissues are functioning. In a PET scan, a patient receives a tiny dose of a radioactive tracer that emits positrons, the antimatter counterparts of electrons. When a positron encounters an […]
