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 / 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 / Your body's secret sugar code could predict disease years before it strikes
Scientists have found that hidden health signals coating your cells could change medicine forever. The new study by Edith Cowan University (ECU) School of Medical and Health Sciences has shown sugar molecules in your body ...
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 / 50-megapixel Earth models capture storms in unprecedented detail—but four consistent blind spots remain
Traditional global climate models were like early digital cameras—they had only about 10,000 pixels to cover the entire planet. At that low resolution, big storm systems looked like blurry blobs. You couldn't see their true ...
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 / 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 / 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 / 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 ...
