Phys.org / Megawatt structured light arrives with 3,070 optical vortices in one array
Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two fundamental limitations have ...
Phys.org / Hat wars of early modern England reveal how manners make the rebel
From refusing to doff hats in court to resisting hat-snatching highway robbers, England's relationship with hats goes far deeper than fashion, new research shows.
Phys.org / Simple vineyard growing practice impacts soil microbiome deep below surface
Pennsylvania is the fourth-largest wine producer in the United States, according to the Pennsylvania Department of Agriculture. The industry supports nearly 11,000 jobs and directly contributes $1.77 billion to the state ...
Phys.org / Street green space can help cool cities, but it will not be enough on its own
A new IIASA-led study finds that expanding street green space can reduce urban heat stress in cities worldwide, but even ambitious greening efforts are unlikely to offset a significant share of the additional heat expected ...
Phys.org / Hidden ocean feedback loop could accelerate climate change
The world's oceans may be quietly amplifying climate change in ways scientists are only beginning to understand. In a new study published in Proceedings of the National Academy of Sciences, University of Rochester scientists—including ...
Medical Xpress / What does it mean to be well? Research delivers building blocks for good mental health
For decades, "mental well-being" has been one of the most used, but least agreed upon, terms in mental health. Now, a landmark study led by Adelaide University and Be Well Co has brought alignment to one of mental health's ...
Medical Xpress / Novel gene-based therapy helps nerves heal better after severe injury
Peripheral nerve injuries, often caused by traumatic events such as car accidents, falls or battlefield injuries, can leave patients with long-term weakness, numbness or loss of function. Despite surgery and advances in understanding ...
Phys.org / Non-producing oil and gas wells may emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study led by McGill University researchers. "Origins of Subsurface ...
Medical Xpress / Study identifies why nightmares persist in children and how to break the cycle
Research from the University of Oklahoma and the University of Tulsa proposes a new model to explain why nightmares can persist over time in children and how therapy can be designed to break that cycle.
Medical Xpress / Surprising finding in the eye may explain how we see in low light
A new Yale School of Medicine (YSM) study has uncovered surprising new details about how our eyes process what we see. When we look at something, our visual system breaks down different aspects of the scene—such as color, ...
Phys.org / Artemis astronauts to shed light on space health risks
While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation—a danger of space travel that NASA is ...
Phys.org / ESA's Celeste broadcasts first navigation signal from low Earth orbit
The European Space Agency has achieved a European first with Celeste, successfully transmitting a navigation signal from low Earth orbit, following the launch of the mission's first satellites on March 28.
