Phys.org / Tiny antennas bring electrical energy to 'unpowerable' nanoparticles
A new technique uses "molecular antennas" to funnel electrical energy into insulating nanoparticles, creating a new class of ultra-pure near-infrared LEDs for medical diagnostics, optical communications, and sensing.
Phys.org / Central America's 'five great forests' are lifelines for North America's migratory birds
Every spring, the familiar songs of Wood Thrushes and warblers return to the parks and backyards of eastern North America. But their journey begins far to the south—in the lush, remote forests of Central America that sustain ...
Phys.org / How mega-constellations are learning to manage themselves
Satellite mega-constellations are quickly becoming the backbone of a number of industries. Cellular communication, GPS, weather monitoring and more are now, at least in part, reliant on the networks of thousands of satellites ...
Phys.org / Ancient bog growth reveals shifting Southern Hemisphere winds 15,000 years ago
Scientists have revealed that ancient bogs in the Southern Hemisphere hold clues to a major shift in Earth's climate thousands of years ago.
Medical Xpress / Three times as many lung cancer deaths could be prevented with one simple step
Three times as many lung cancer deaths could be prevented if everyone eligible for screening got a chest CT scan, a new study says.
Phys.org / Researchers find simple way to destroy PFAS on activated carbon
Researchers at Clarkson University have discovered a new way to destroy "forever chemicals," known as PFAS, using only stainless steel ball milling equipment. The method does not need added chemicals, heat, or solvents.
Phys.org / Stars forge elements in new, uncharted ways: Experimental physicist discusses the 'i-process'
All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a nucleus heavier than iron ...
Phys.org / Sharper MRI scans may be on horizon thanks to new physics-based model
Researchers at Rice University and Oak Ridge National Laboratory have unveiled a physics-based model of magnetic resonance relaxation that bridges molecular-scale dynamics with macroscopic magnetic resonance imaging (MRI) ...
Phys.org / Single-celled organisms have more complex DNA epigenetic code than multicellular life, researchers discover
Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and ...
Phys.org / Most homemade dog diets lack nutrients, study finds
Over the last two decades, homemade diets have seen a rise in popularity among dog owners. However, new research from the Dog Aging Project (DAP) reveals that most homemade diets are missing important nutrients that dogs ...
Phys.org / Soil food webs boost carbon retention in farmlands, finds study
Researchers from the Institute of Applied Ecology (IAE) of the Chinese Academy of Sciences (CAS) have uncovered how soil food webs promote the transformation and storage of photosynthetic carbon in farmlands. Their results ...
Phys.org / New cable design mitigates flaws in superconducting wires
When current flows through a wire, it doesn't always have a perfect path. Tiny defects within the wire mean current must travel a more circuitous route, a problem for engineers and manufacturers seeking reliable equipment.
