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 / Prehistoric fossil poses puzzles in shark research
A newly examined prehistoric shark from the age of dinosaurs provides surprising insights into the early evolution of modern sharks. It cannot be confidently assigned to any shark order that exists today and thus calls into ...
Phys.org / Gotland hunter-gatherer graves hint at how Stone Age families organized
A woman was buried with two children, but they were not her own. In another grave, two children were placed. They were not siblings and were more distantly related, perhaps cousins. In a new study published in the Proceedings ...
Phys.org / Rhythm during sex in bonobos provides new insights into the evolution of communication
An international research team, including VUB data scientist Yannick Jadoul, has shed new light on the rhythmic nature of sexual behavior in bonobos. By precisely analyzing the tempo of movements during sex, researchers aim ...
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 / 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 / Tropical forests generate rainfall worth billions, study finds
Tropical forests help to generate vast amounts of rainfall each year, adding weight to arguments for protecting them as water and climate pressures increase, say researchers. A new study led by the University of Leeds has ...
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 / 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 / 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 / Climbing behaviors of tree-dwelling mammals unlock insights on early primate evolution
Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures seen in primates. The ...
Phys.org / Northern Europe's radiator: Volcanic eruptions in the past may have pushed ocean currents toward collapse
New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures ...
