Measurements of the quark pressure distribution in the proton reveal a strong repulsive pressure near the proton’s centre (stronger than the pressure in neutron stars) and a binding pressure at greater distances. | Continue reading
Previous studies suggest that individual differences in intelligence correlate with circuit complexity and dendritic arborization in the brain. Here the authors use NODDI, a diffusion MRI technique, to confirm that neurite density and arborization are inversely related to measure … | Continue reading
A designer compound stops rhinoviruses in their tracks. | Continue reading
Materials whose optical properties can be reconfigured are crucial for photonic applications such as optical memories. Phase-change materials offer such utility and here recent progress is reviewed. | Continue reading
As the United Nations prepares a historic treaty to protect the oceans, scientists highlight what’s needed for success. | Continue reading
Humans and other mammals are prodigious learners, partly because they also ‘learn how to learn’. Wang and colleagues present a new theory showing how learning to learn may arise from interactions between prefrontal cortex and the dopamine system. | Continue reading
Natural or artificially induced electrical activity changes can alter ion balance so as to briefly influence firing. An optogenetics study delineates one mechanism: Cl− shifts causing seconds-long excitability changes after silencing. | Continue reading
This Review Article examines the development of wearable sweat sensors, considering the challenges and opportunities for such technology in the context of personalized healthcare. | Continue reading
This Perspective highlights the existence of gaps between the computational complexity and energy efficiency required for the continued scaling of deep neural networks and the hardware capacity actually available with current CMOS technology scaling, in situations where edge infe … | Continue reading
Physicists believe that at the tiniest scales, space emerges from quanta. What might these building blocks look like? | Continue reading
Eric Topol extols a gripping account of the rise and fall of the US medical-testing company. | Continue reading
Grid-like representations emerge spontaneously within a neural network trained to self-localize, enabling the agent to take shortcuts to destinations using vector-based navigation. | Continue reading
Twenty years on, Dave Reay speaks out about the depression that almost sunk his PhD, and the lifelines that saved him. | Continue reading
The BIG Bell Test, which used an online video game with 100,000 participants worldwide to provide random bits to 13 quantum physics experiments, contradicts the Einstein–Podolsky–Rosen worldview of local realism. | Continue reading
Deep-learning algorithm spontaneously mimicked the activity of specialized neurons that tell us where we are in space. | Continue reading
Mental illness can be devastating — but there are ways to fight it, say four researchers who have known those bleak times. | Continue reading
An artificial-intelligence technique called deep learning has now been used to model spatial navigation. The system develops a representation of space similar to that of the grid cells found in the mammalian brain. | Continue reading
NASA’s Cold Atom Laboratory will allow physicists to play with quantum phenomena like never before. | Continue reading
Paul Halpern celebrates the oeuvre of the brilliant, unconventional scientist. | Continue reading
Carbon emissions from tourism are rising at an alarming rate. | Continue reading
Peace efforts in the country have ended 50 years of intense conflict. Now, scientists are studying former fighters and victims as they attempt to heal. | Continue reading
The publishing system builds in resistance to replication. Paul Gertler, Sebastian Galiani and Mauricio Romero surveyed economics journals to find out how to fix it. | Continue reading
