Phys.org / Safe injection method for traditional topical antibiotic could reduce antibiotic resistance
Widely used to prevent infection, one of the active ingredients in the ointment, Neosporin, is neomycin. Discovered in the 1940s, neomycin is an effective topical antibiotic; however, if injected into the body to treat systemic ...
Phys.org / New 3D model reveals geophysical structures beneath Britain
Magnetotelluric (MT) data, which contain measurements of electric and magnetic field variations at Earth's surface, provide insights into the electrical resistivity of Earth's crust and upper mantle. Changes in resistivity, ...
Phys.org / Dancing proteins keep cells moving: Redefining the function and role of key factors in actin filament disassembly
Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to be closed or chase down bacteria in the bloodstream. This mobility is provided by the cytoskeleton, ...
Phys.org / Resolving the stonefly phylogeny puzzle via mitochondrial genomes
Stoneflies (order Plecoptera) rank among the most ancient lineages of winged insects. Beyond their role as key bioindicators for evaluating freshwater ecosystem health, they carry ecological value and evolutionary significance.
Phys.org / A new system can dial expression of synthetic genes up or down
For decades, synthetic biologists have been developing gene circuits that can be transferred into cells for applications such as reprogramming a stem cell into a neuron or generating a protein that could help treat a disease ...
Phys.org / How the brain's internal central clock controls rhythmic foraging
Why do animals search for food at specific times of the day? In a study published in Current Biology, a research group led by Prof. Li Yan from the Institute of Biophysics of the Chinese Academy of Sciences has uncovered ...
Phys.org / DNA repair mechanisms help explain why naked mole-rats live a long life
Naked mole-rats are one of nature's most extraordinary creatures. These burrowing rodents can live for up to 37 years, around ten times longer than relatives of a similar size. But what is the secret to their extreme longevity? ...
Phys.org / Satellite images reveal ancient hunting traps used by South American social groups
Satellite images have revealed an ancient system of elaborate, funnel-shaped mega traps likely built by hunters and pastoralists to catch prey in the high altitudes of northern Chile.
Phys.org / A new scalable approach to realize a quantum communication network based on ytterbium-171 atoms
Quantum networks, systems consisting of connected quantum computers, quantum sensors or other quantum devices, hold the potential of enabling faster and safer communications. The establishment of these networks relies on ...
Phys.org / Saturday Citations: AI chatbots are insincere; childhood memory recall; a tiny chunk of dark matter
This week, researchers discovered so-called "switchbacks" in Earth's magnetic field similar to observations of switchbacks in the sun's magnetic field. Scientists provided more evidence that ancient Rapa Nui engineers "walked" ...
Phys.org / Breakthrough mirror-image nanopores open door to new biomedical applications
For the first time, researchers have successfully fabricated and characterized a fully functional mirror-image nanopore—a molecular gateway built entirely from D-amino acids, the mirror-image forms of the natural building ...
Phys.org / Fundamental engineering principles can help identify disease biomarkers more quickly
People often compare the genome to a computer's program, with the cell using its genetic code to process environmental inputs and produce appropriate responses.
