Dialog / Hydroclimate whiplash damages California's tallest redwoods after years of drought
Tall trees are generally associated with high-biomass forests. This is particularly true for forests dominated by Sequoia sempervirens (hereafter redwood), the world's tallest tree species. Extreme decay resistance, the ability ...
Phys.org / 3D atomic imaging reveals a new pathway to crystal formation
The most common scientific approach for thinking about how condensation, freezing and other phase transitions begin is based in classical nucleation theory, which was developed about a century ago. Thousands of experiments ...
Phys.org / Microcline reveals how a common mineral surface triggers ice formation in clouds
Pure water freezes only at around -38°C (-36°F). Tiny mineral dust particles act as so-called ice nucleators—crystallization seeds on which ice crystals form. A research team at Bielefeld University and the University of ...
Phys.org / Using plutonium to probe the universe: Magneto‑ν experiment advances dark matter and neutrino research
Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...
Phys.org / Machine learning method uncovers hidden patterns in DNA methylation
In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome. The machine-learning method identifies differentially methylated DNA regions ...
Phys.org / Developing a genetic toolkit for manipulating abundant intestinal microbes
Weill Cornell Medicine investigators have developed a set of molecular tools to regulate the activity of specific genes in one of the most common classes of intestinal bacteria. The ability to genetically manipulate these ...
Phys.org / Electron beams cut poultry pathogens while preserving turkey quality
Researchers are gauging the effectiveness of electron beams in the fight against foodborne pathogens in poultry. "Impact of Electron Beam (eBeam) Treatment on Meat Quality and Sensory Attributes of Ground Chicken and Turkey" ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
Phys.org / Chemists harness light to build 3D molecular structures for drug discovery
Researchers from the Department of Chemistry at The University of Hong Kong (HKU), led by Professor Jian He and collaborators, have developed a new light-driven method for constructing three-dimensional molecular building ...
Phys.org / Simulations reveal asymmetric diffusion of magnetic skyrmions through an off-center gate
Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a key role in many fields, including physics, biology and economics. In particular, asymmetric or ...
Phys.org / Could 12 inches of rain hit New York City? AI maps plausible rare storms
Can a city's seawall stand up to a blockbuster storm? Will a region's power grid hold against record-breaking heat? And can a town's firefighting resources contain a major wildfire?
Phys.org / Chemical physicists quantitatively model electron interactions in real quantum materials
A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous ...
