New insight into the neurobiological roots of being a ‘morning person’ or ‘night owl’
Human beings exhibit marked differences in habits, lifestyles and behavioral tendencies. One of these differences, known as chronotype, is the inclination to sleep and wake up early or alternatively...
Study shows that duality operators can be realized as unitary linear-depth quantum circuits
In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been...
Clustered neurons in bat midbrain encode categories of vocalizations, study finds
The ability to quickly recognize sounds, particularly the vocalizations made by other animals, is known to contribute to the survival of a wide range of species. This ability is supported by a...
Parallel activity in orbitofrontal cortex and hippocampus shapes cognitive maps and schemas, study suggests
As humans and other animals navigate their surroundings and experience different things, their brain creates so-called cognitive maps, which are internal representations of environments or tasks....
The first experimental observation of Dirac exceptional points
Exceptional points (EPs) are unique types of energy-level degeneracies that occur in non-Hermitian systems. Since their existence was first proposed more than a century ago, physicists have only...
Assessing the potential of hydrogen and carbon dioxide networks for the future of European energy systems
Over the past decades, many countries worldwide have been trying to gradually transform their energy systems, with the aim of reducing carbon emissions and mitigating the adverse effects of climate...
Molecular engineering approach could boost hydrogen evolution reaction activity by up to 50 times in alkaline media
Electrolyzers are devices that can split water into hydrogen and oxygen using electricity and via a process known as electrolysis. In the future, these devices could help to produce hydrogen gas...
Flying squirrel-inspired drone with foldable wings demonstrates high maneuverability
Unmanned aerial vehicles (UAVs), commonly known as drones, have already proved to be valuable tools for a wide range of applications, ranging from film and entertainment production to defense and...
Nasal microbiome may help explain link between olfactory dysfunction and cognitive decline
As humans age, particularly after middle age, their brain functions, cognitive abilities and memory can deteriorate to varying degrees. Aging-related disorders marked by cognitive decline,...
Passivation technique reduces defects in kesterite solar cells to achieve 11.51% efficiency
Over the past few decades, solar cells have become increasingly widespread, with a growing number of individuals and businesses worldwide now relying on solar energy to power their homes or...
