Phys.org / Research reveals cosmic tug-of-war behind the Crab Pulsar's zebra stripes
For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating from the Crab Pulsar, the remnant of a supernova observed by Chinese and Japanese astronomers in the ...
Phys.org / Chemists create complex DNA structures without hydrogen bonds
No "sticky ends"? No problem. A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental ...
Phys.org / Limiting global warming can reduce US wildfire smoke-related deaths by thousands annually
Using future climate scenarios based on wildfire damages in North America, scientists estimate that up to 10,000 or more lives may be saved annually in the United States if society is able to mitigate climate change by keeping ...
Phys.org / Greenhouse gas fluxes in Everglades provide path for maximizing carbon capture via water management
The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system ...
Phys.org / Porpoises can 'turn down the volume' to withstand ship noise
Porpoises are entirely dependent on their hearing for survival. They navigate, hunt, and communicate by emitting rapid click sounds and listening to the returning echoes. However, with increasingly noisy oceans, it is getting ...
Phys.org / Dissolvable hydrogel could enable personalized bone implants
Bones broken in a skiing accident usually heal on their own. But if the break is too severe or a bone tumor needs to be removed, surgeons insert an implant that enables the bone to grow back together. Implants often consist ...
Phys.org / Mott and Kondo insulators—how external stimuli can modify electronic energy bands
A study from the Research Center for Materials Nanoarchitectonics (MANA) has uncovered a theoretical mechanism showing how the electronic band structures of strongly correlated insulators can be reshaped by spin and charge ...
Phys.org / Catching light in air: Programmable Mie voids boost light matter interaction
Atomically thin semiconductors such as tungsten disulfide (WS2) are promising materials for future photonic technologies. Despite being only a single layer of atoms thick, they host tightly bound excitons—pairs of electrons ...
Phys.org / Isolating vesicle-cloaked viruses in city and hospital wastewater
Viruses such as human norovirus can travel in vesicles, small fluid-filled sacs that are like shipping containers for cells. Viruses hidden in these containers are often harder to detect and may be more infectious than free-floating ...
Phys.org / Scientists rescue lost song of the critically endangered regent honeyeater
Scientists from The Australian National University (ANU) and the Taronga Conservation Society Australia have successfully restored the lost traditional song of one of Australia's most endangered birds, offering new hope for ...
Phys.org / Oman ophiolite study suggests subduction zones can lock away CO₂
A research team led by a Keele scientist has shed new light on how a mysterious rock formation in Oman was created, which could reveal new details about Earth's ability to store carbon dioxide (CO2). The study, led by Dr. ...
Phys.org / Soil saturation data sharpens atmospheric river flood warnings, study of 71,000 storms finds
Atmospheric rivers carry unfathomable amounts of water across the sky, bringing moisture to drought-stricken regions like the Western U.S. But whether a particular incoming atmospheric river storm will result in disastrous ...
