Phys.org / An elegant modification doubles the range of low-noise 'white lasers' in a single fiber
Supercontinuum light sources—often called "white lasers" because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers ...
Phys.org / Two decades of blazar observations, and the mysteries keep piling up
Narrow jets of luminous matter may be emitted toward Earth from the nuclei of active galaxies billions of light-years away. The galaxy then appears as a point source and is called a blazar. A Polish-German team of scientists ...
Phys.org / Trillion-mile gas streamer may explain tilt of triple-star system's outer planet-forming ring
A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has captured a massive stream of gas—one trillion miles, or 0.2 light-years, long—feeding the young triple-star system GW Orionis. These ...
Phys.org / Never-before-seen woven structure that forms naturally inside a crystal discovered
For the first time, scientists have observed a three-dimensional woven structure forming naturally inside a crystal, revealing a previously unknown way in which matter can organize itself.
Phys.org / Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050
The Arctic is warming at an accelerating pace. As permafrost thaws across vast areas and wildfires become more frequent, large amounts of methane (CH4) are being released. Together, these changes are reshaping the region's ...
Phys.org / Liquid nitrogen may have recently flowed across Pluto's heart-shaped glacier
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier ...
Phys.org / One-third of agricultural land accounts for two-thirds of global impact, study reveals
Agriculture covers more than 40% of Earth's habitable land and plays a central role in both climate change and biodiversity loss. Yet the impact of agriculture is far from evenly distributed across space.
Phys.org / Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up ...
Phys.org / Bacterial enzyme switch could weaken antibiotic defenses in MRSA and other pathogens
If you ask Vijay Parashar, associate professor of medical and molecular sciences (MMSC) at the University of Delaware College of Health Sciences, human bodies are bags of bacteria. "It sounds gross, but not all bacteria are ...
Phys.org / Sugars may have helped fuel the evolution of the human brain, new research suggests
Fruit, honey and other naturally sweet foods may have helped fuel the evolution of the human brain, according to new research from the University of Sydney and the University of Glasgow.
Phys.org / Bioengineers develop biochemical halo to cloak insulin-producing cells from body defenses
A protein known as interleukin 10 (IL-10) is the lynchpin of a new method to protect transplanted cells from host immune system attacks. Rice University researchers engineered a living factory to produce a localized biochemical ...
Phys.org / Atomic view of Alzheimer's disease peptide could inform new drugs
One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide ...
