Phys.org / Life in balance: Ancient Andean scales illuminated by new research
New research from the University of St Andrews has discovered how Incas used Andean balance scales and ancient string knot writing known as "khipus," in association with sacred, animate landscapes.
Phys.org / Novel mRNA therapy curbs antibiotic-resistant infections in preclinical lung models
Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have reported early success with a novel mRNA-based therapy designed to combat antibiotic-resistant bacteria.
Phys.org / Uncovering a new genetic code in archaea opens doors for bioengineering applications
The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in which one or two additional ...
Phys.org / Ultrafast UV-C laser pulses generated and detected using 2D materials
Scientists have developed a new platform for the generation and detection of ultrashort UV-C laser pulses on femtosecond timescales. This breakthrough could unlock new opportunities for transforming optical wireless communication ...
Phys.org / Counting salmon is a breeze with airborne eDNA
During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden Yincheong Ip, a UW research ...
Phys.org / Starquakes reveal red giant's turbulent history and rapid spin in black hole system
Astronomers from the University of Hawaiʻi Institute for Astronomy (IfA) have uncovered the turbulent past of a distant red giant by listening to its celestial "song." Subtle variations in the star's brightness suggest that ...
Phys.org / Plants use engineering principles to push through hard soil
Across the globe, soil compaction is becoming an ever more serious challenge. Heavy vehicles and machinery in modern agriculture compress the soil to such an extent that crops struggle to grow. In many regions, the problem ...
Phys.org / Sensor-integrated food wrapper can facilitate real-time, non-destructive detection of nutritional components
Food quality and safety are crucial. However, conventional food-monitoring methods, including ribotyping and polymerase chain reaction, tend to be destructive and lengthy. These shortcomings limit their potential for broad ...
Phys.org / Climate change could expand habitats for malaria mosquitoes, researchers warn
An insistent buzzing at sunset followed by itchy, spotted legs. Here in Denmark, mosquitoes are mostly an annoying—but generally harmless—nuisance. That is far from the case in many parts of the world.
Phys.org / Helping to grow plants in space for NASA missions to the moon and mars
Imagine biting into a crisp, garden-fresh salad and savoring juicy strawberries for dessert. But instead of your backyard, you're gazing out at a stark lunar landscape, Earth hanging like a precious blue marble in the inky ...
Phys.org / Meteorite crater hosts methane-making microbes—a clue to life on Mars?
Scientists have discovered living microbes producing methane in the fractured rocks deep inside Sweden's Siljan impact crater, offering insights into Earth's earliest life and the search for life beyond our planet.
Phys.org / Exceptional points alter the order of lasing modes
Exceptional points (EPs) are non-Hermitian singularities where two or more eigenstates coalesce, resulting in the eigenspace collapsing in dimensionality. Over the past decade, researchers have uncovered a wealth of exotic ...
