Phys.org / Why don't antibiotic-making bacteria self-destruct?
Early in 2025, scientists discovered a promising new antibiotic in a soil sample from a lab technician's backyard. The molecule, called lariocidin, is produced by the microbe Paenibacillus and shows broad activity against ...
Phys.org / CRISPR–Cas3 genome-editing system holds therapeutic potential
Genetic disorders occur due to alterations in the primary genetic material—deoxyribonucleic acid (DNA)—of an organism.
Phys.org / Rocks and rolls: The computational infrastructure of earthquakes and physics of planetary science
Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye view, studying the planet's ...
Phys.org / Researchers film foraging strategy of wood mice choosing between healthy and moth-damaged chestnuts
A mouse scurries up to six chestnuts. Three look healthy. Three have exit holes where moth larvae ate the insides before they left. What does the mouse do?
Phys.org / Detailed map reveals groundwater levels across the U.S.
How much fresh water is in the United States? It's a tough question, since most of the water is underground, accessible at varying depths. In previous decades, it's been answered indirectly from data on rainfall and evaporation. ...
Phys.org / Atomic-level surface control boosts brightness of eco-friendly nanosemiconductors by 18-fold
Light-emitting semiconductors are used throughout everyday life in TVs, smartphones, and lighting. However, many technical barriers remain in developing environmentally friendly semiconductor materials.
Phys.org / Bulk inorganic crystals grown from water emit 'handed' light
Researchers at Kumamoto University have discovered that a purely inorganic crystal grown from water solution can emit circularly polarized light, a special form of light whose "handedness" distinguishes left from right.
Phys.org / Ancient teeth are treasure troves of data on Iron Age lifestyles
Teeth provide a wealth of information about the lives of Iron Age Italians, according to a study published in the open-access journal PLOS One by Roberto Germano of Sapienza University of Rome, Italy and colleagues.
Phys.org / Avocadoes may become easier to grow in India—but not if global emissions remain high
A new study suggests that with low to moderate levels of global greenhouse emissions in coming decades, more of India could become suitable for growing avocadoes. However, with high enough emissions, growing zones could shrink ...
Phys.org / British redcoat's lost memoir reveals harsh realities of life as a disabled veteran
Archival discoveries including a 19th-century autobiography transform our understanding of Shadrach Byfield, an English veteran of the War of 1812 who buried his own amputated arm and designed a custom prosthesis.
Phys.org / Chemists determine structure of fuzzy coat that surrounds Tau proteins
One of the hallmarks of Alzheimer's disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.
Phys.org / What happens when fire ignites in space? 'A ball of flame'
When fire breaks out in the low-gravity, high-stakes conditions inside spacecraft or space stations, it behaves very differently than back here on Earth.
