Medical Xpress / Being physically fit may keep you calm under pressure
Regular exercise is not only good for the body, but it may also help you stay cool under pressure. Research published in the journal Acta Psychologica found that higher cardiorespiratory fitness (CRF) is associated with lower ...
Phys.org / Long-term radio observations probe a relativistic binary pulsar system
Astronomers have analyzed the data from long-term radio observations of a binary pulsar known as PSR J1906+0746. Results of the new study, published February 5 on the arXiv pre-print server, deliver important information ...
Phys.org / Horses with over 30 minutes of REM sleep show better persistence in learning tasks
Just as for humans, sufficient sleep supports learning and coping for horses. A recent study at the University of Helsinki indicates that short periods of REM sleep impair horses' perseverance and performance in demanding ...
Phys.org / JWST spots most distant jellyfish galaxy to date
Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them. ...
Phys.org / Renewable biological catalyst carries the potential to transform wastewater into phosphorus resource
Phosphorus is an essential nutrient for plants and managing its availability is critical for growing crops to maintain the global food supply. In an effort to move toward a more sustainable bioeconomy, researchers from the ...
Phys.org / New amplifier design promises less noise, more gain for quantum computers
The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), RIKEN researchers have ...
Phys.org / A yeast enzyme helps human cells overcome mitochondrial defects
Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning mitochondria, the organelles ...
Phys.org / Climate change widened Valencia's 2024 extreme rain footprint by 55%, study finds
Human-driven climate change intensified rainfall that triggered Spain's deadliest natural disaster in a generation when flash floods hit the Valencia region in 2024, a new study showed on Tuesday.
Phys.org / Satellite imagery and AI reveal development needs hidden by national data
For years, Iceland, Switzerland, and Norway have ranked near the top of the United Nations' annual index of countries based on indicators of well-being and quality of life. Countries with more poverty and less access to health ...
Phys.org / Plasma rotation simulations could help fusion reactors survive decades of use
Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the magnetic fields that ...
Phys.org / Off-the-shelf components enable deployment-ready quantum entanglement source
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states ...
Phys.org / Strong correlations and superconductivity observed in a supermoiré lattice
Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can ...
