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 / Walking shark discovery reveals new species in tiny Papua New Guinea range
A night dive to study wild sharks that can walk on land has surfaced with something even rarer—a species unknown to science. "New shark species don't come along that often, and it's most definitely the first one named after ...
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 / 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 / Intensive nickel mining has transformed microbial biodiversity of Thio Lagoon in New Caledonia
A study carried out by scientists from Ifremer, IRD, the universities of Western Brittany (UBO) and Bordeaux, CNRS, and the University of Tartu (Estonia) reveals the impact of nickel mining on the coastal ecosystems of New ...
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 / 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 / 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 / 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 / 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 / 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 / Young coqui frogs 'play it safe' when disease strikes, study finds
For a frog no bigger than a fingernail, survival depends on how it spends every bit of energy. New research from the University of Florida shows that young frogs prioritize growing quickly even when infected with a deadly ...
