Phys.org / Self-assembling luminophores reveal new design principle for efficient light-energy transport
In biological systems, especially for protein molecules, the formation of nanotubular structures is often guided by molecular folding. The folding process organizes interaction sites and enables the formation of complex architectures ...
Phys.org / How maze-like magnetic patterns form and evolve in materials
The rapid increase in electric vehicle adoption in recent years has highlighted a crucial issue: the energy conversion efficiency of electric motors. In electric motors, iron loss or magnetic hysteresis loss is a primary ...
Phys.org / AI algorithm identifies cells across diverse biological images, cutting hours of manual labeling
Imaging is a critical technique in biology—from identifying cancerous cells in biopsies to observing how immune cells like macrophages hunt down and destroy pathogens. Traditionally, distinguishing and labeling individual ...
Phys.org / Migratory blackcap bird brain mapped for the first time, opening a new era of 3D digital atlases
A migratory bird brain, the Eurasian blackcap (Sylvia atricapilla), has been mapped for the first time using high-resolution light microscopy. The open-source software tools developed, and the detailed processes published, ...
Phys.org / Cells 'switch' on protein factories after injury, study finds
Scientists have uncovered a novel mechanism through which skin cells organize and control protein production during homeostasis and wound healing, according to a new study published in Developmental Cell. The findings offer ...
Phys.org / Emojis trigger brain responses like real faces within 160 milliseconds, study finds
Facial expressions are a fundamental aspect of human social interaction. While emojis are an extremely popular way for people to communicate, very little is known about the psychological response that they can generate. A ...
Phys.org / 'Tis the season: Sharing resources sustains ocean microbial biodiversity
Oceanographers from the University of Hawai'i at Mānoa discovered that microbial communities—from the sunlit surface to extreme depths—in the North Pacific Subtropical Gyre exhibit robust seasonal cycles. The study provides ...
Phys.org / Atlantic current shows two-decade decline across four deep-ocean monitoring sites
A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on ...
Phys.org / These blazing blue explosions may be born when a compact dead star slams into a Wolf-Rayet star
Luminous fast blue optical transients (LFBOTs) are among the universe's brightest and fastest explosions but their origin is not completely understood. A new study takes a closer look at the galaxies they occur in, offering ...
Phys.org / Hollow-sphere catalyst enables greener production of 99% pure propene at room temperature
The world's appetite for propene (propylene) is growing faster than the chemical industry can keep up. This petrochemical product powers the production of acrylonitrile, propylene oxide, high-velocity fuels, and, most importantly, ...
Phys.org / Quantum model explains how single electrons cause damage inside silicon chips
Researchers in the UC Santa Barbara Materials Department have uncovered the elusive quantum mechanism by which energetic electrons break chemical bonds inside microelectronic devices—a detrimental process that slowly degrades ...
Phys.org / Sulfur-rich Mercury magmas behave differently than Earth's do
Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It ...
