Phys.org / Female chickadees seek cognitively skilled males for extra‑pair matings, study shows
Female chickadees living in monogamous mating systems will proactively seek out males that have better cognitive skills than their nest mate, according to new findings.
Phys.org / New method enables accurate sequencing of short peptides hidden in food and human body
Our food and our bodies are full of tiny protein fragments called peptides. These small chains of amino acids act as biological messengers, influencing processes ranging from sensory perception to physiological functions.
Phys.org / One of the world's most important plate boundaries is older than previously thought
A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific Plate dives beneath ...
Phys.org / RNA barcoding approach reveals previously unknown virus–host relationships
An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages—viruses that infect bacteria—and their bacterial hosts, offering a powerful new tool for next-generation ...
Phys.org / Honeybees adjust their dances based on information reliability, study reveals
A new study demonstrates that honeybees can evaluate the reliability of their own communication, actively adjusting the vigor of their "waggle dance" based on the truthfulness of the information they provide. By manipulating ...
Phys.org / Silicon-compatible nanocomposite garnet enables better, simpler optical isolators
A research team from Tohoku University and Kyocera Corp. has developed a new magneto-optical material—a nanocomposite magnetic garnet film—that can be deposited directly onto silicon substrates while delivering a magneto-optical ...
Phys.org / Distant ocean temperatures found to influence snowfall in Antarctica
Snowfall deep inside East Antarctica has increased in recent decades, and distant ocean temperature changes may be partly responsible. Using long-term climate data and observations from Dome Fuji station, researchers found ...
Phys.org / AI system evaluates chemical spectra in minutes
A research team has developed an artificial intelligence (AI) system that proposes suitable molecular structures from the raw data of spectroscopic measurements and assesses their plausibility. The system is openly accessible ...
Phys.org / Observation of living cells solves mystery of bacterial cell division
Using an innovative combination of biochemical experiments and ultra-high-resolution microscopy, a research team at Kiel University has solved the long-standing mystery of how the bacterium B. subtilis regulates its cell ...
Phys.org / Intermolecular collisions may explain why organic radical fluids become unusually magnetic
Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously ...
Phys.org / Random deformation lets glassy materials store precise mechanical memories, simulations reveal
Amorphous materials such as glass are solids whose internal structure lacks a repeating pattern. Their molecules are arranged in a random and irregular way. Surprisingly, these disordered materials can "remember" past mechanical ...
Phys.org / Chandra tracks M87 black hole's evolving jet in finest X-ray detail yet
An international team of astronomers led by Camille Poitras, a Ph.D. student in the Faculty of Science and Engineering at Laval University, has produced the most detailed X-ray view ever obtained of the jet launched by the ...
