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 / 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 / Global surveys find carbon uptake in tropics overestimated
An international team of researchers has found plants in the tropics absorb much less carbon dioxide than previous modeling had suggested, which has implications for ecosystem management.
Phys.org / LiON: A fluorescent molecule tracks iron and oxygen levels in individual cells
A new fluorescent reporter capable of visualizing biologically active iron and oxygen inside living cells at single-cell resolution has been developed, as reported by researchers from Science Tokyo. Using this new tool, they ...
Phys.org / Nanomedicine discovery uses salt to overcome major obstacle in gene therapy
Researchers at the University of Houston's College of Pharmacy have discovered an unexpectedly simple strategy to improve the performance of mRNA vaccines and gene therapeutics: adding salt. The findings, published in Small, ...
Phys.org / Cockatoos learn when touchscreen rewards 'die,' then apply rule to new contexts
For humans, death is surrounded by culture, emotion, ritual and language. But the question can be framed in a much more basic way: What would an animal have to understand in order to recognize that someone has died?
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 / Data suggest 'red flag' laws are linked to sustained reductions in arrests
Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the ...
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 / Artificial cells gain porous membranes, enabling lab reactions and drug release
Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at the Max Planck Institute ...
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 / 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 ...
