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 / 2,700-year-old standing stone may provide fresh evidence for King Hezekiah's religious reforms
A new study by Prof. Avraham Faust of Bar-Ilan University's Department of General History presents new evidence that may shed light on one of the most debated questions in the study of Israelite religion: Did King Hezekiah's ...
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 / Revealing how and when a black hole's mighty winds can squash star formation
Thanks to the X-Ray Imaging and Spectroscopy Mission, or XRISM, University of Michigan researchers are helping chip away at one of astronomy's cosmic mysteries: The universe's most massive galaxies appear to be missing stars.
Phys.org / AI decodes plant DNA 'switches' to better predict gene control
An international research team led by Forschungszentrum Jülich and the IPK Leibniz Institute has developed an artificial intelligence model that predicts where regulatory proteins dock onto plant DNA to switch genes on and ...
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 / 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 / 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 / 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 / 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 / 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 ...
