Phys.org / Nanoparticle combines two strategies to speed up the healing of chronic wounds
Researchers at the University of São Paulo (USP) in Ribeirão Preto, Brazil, have developed a nanoparticle that can address the various factors hindering the healing of chronic wounds, which include ulcers associated with ...
Phys.org / Fibrinogen discovery reshapes understanding of how wounds heal
Scientists have redefined how the key blood-clotting protein fibrinogen behaves when it contacts air, overturning two decades of scientific consensus on wound healing. It is the culmination of more than a decade of international ...
Phys.org / Intense light bent out of shape—ultrafast lenses made from gas
Researchers from the MPIK in Heidelberg used an atomic gas as a time-dependent lens to shape and spectrally manipulate intense high-frequency laser pulses. This gas-based optical element could pave the way toward better XUV- ...
Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Phys.org / Soil methane sink may be larger than thought, three-model analysis finds
Methane-munching microbes in soil might be more important than previously thought, a new study finds. Soil is an important carbon sink, and scientists are still learning much about the diversity of its microbial communities. ...
Phys.org / New measurements explain how silicon and diamond achieve extreme reversible stretching
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
Phys.org / Farm mice study shows antibiotic resistance is an environmental problem, not just a medical one
Scientists analyzed the genomes of gut microorganisms from an extensive population of 875 wild house mice (Mus musculus) collected from farms in Germany. They searched for genes responsible for resistance to common antibiotics ...
Phys.org / 'Wall-to-wall' map of NYC trees could help cool cities worldwide
Researchers have created an interactive map identifying 1.8 million individual trees in New York City, using a new approach that could optimize the placement of trees for cooling in cities around the world.
Phys.org / Messy life-producing cellular process caught in action for first time
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Phys.org / Snake bones with flint cuts show Mount Carmel settlers ate reptiles 15,000 years ago
Around 15,000 years ago, the way of life of human communities in the southern Levant underwent a fundamental change. Groups of hunter-gatherers, who until then had been nomadic, reduced their mobility and established small, ...
Phys.org / Extreme rain shifts toward larger, less frequent storms across eastern US
Extreme precipitation events are among the most damaging natural disasters and a major concern in our changing climate. In the U.S., since 1980, the most destructive events alone have caused more than 2,800 deaths and $700 ...
Phys.org / Designing supramolecular therapies to cross the blood-brain barrier
A new Northwestern Medicine study has uncovered key molecular design principles that could help supramolecular therapeutics cross the blood-brain barrier, a major challenge for this novel approach to treating neurological ...
