Leaf resilience to raindrops provides insight into energy harvesting potential
Credit: Pixabay/CC0 Public Domain To a leaf, a falling raindrop has the same mass as a bowling ball falling on a person. So how do leaves survive? A new study sheds light on the physical dynamics that help leaves react to the effects of raindrops, with potential applications in agriculture and renewable energy harvesting. In the paper “Resonance and damping…

Improved spin-density correlation simulations give researchers clearer insight into neutron stars
Neutrinos travel through a gas of neutrons and are sensitive to the correlation between the spin and density of the neutronic material. These correlations determine how much energy is transferred from the neutrino to the neutron. Credit: Dean Lee When a star dies in a supernova, its remains can become a neutron star. Inside a neutron star, protons and electrons…

Scientists gain new insight into how mass is distributed within hadrons
Two-dimensional spatial distribution of mass due to gluons of nucleons (left) and pions (right). It is simulated with a seven-valent pion mass using lattice quantum chromodynamics. Credit: Bigen One Scientists can determine the mass of elementary particles made of quarks by examining the particle’s energy and momentum in four-dimensional spacetime. One of the quantities that encode this information is called…

Study provides molecular insight into sexual dimorphism in chicken feathers
Ovarian-derived estrogen converts default (primitive) male-type feathers into female-type feathers by regulating hormonal systems within the feather follicle. Provided by: Professor Sakae Takeuchi, Okayama University Birds have unique skin appendages called feathers that are derived from the outermost layer of skin cells. Feathers are important for several functions, including flight, temperature regulation, protection from external stimuli, and mating behavior. The…

Study of iron catalysts provides insight into ammonia decomposition
Credit: ACS Catalysis (2024). DOI: 10.1021/acscatal.4c04415 The use of ammonia is considered a promising method to transport hydrogen. But we also need an efficient process to convert it back into hydrogen and nitrogen. An international research team has gained new insights into the mode of operation of iron catalysts that can be used to split ammonia into nitrogen and hydrogen.…
