Phys.org / Quantum properties of multimode light observed despite extreme losses
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. ...
Phys.org / Purine-heavy DNA sequences protect Bacillus subtilis genes from Rho termination
In the study of bacteria, a longstanding dogma has held that two molecular machines—RNA polymerase, which leads the way in transcribing DNA into RNA, and ribosomes, which bring up the rear translating RNA into proteins—worked ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Phys.org / Diffractive networks enable optical information transfer through random and unknown diffusers
The transmission of optical information through random scattering media is a major challenge in optics, biomedical imaging, telecommunications and remote sensing. When light passes through a turbid or diffusive medium, such ...
Phys.org / Instant digital rewards may make hard thinking feel less worthwhile
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward ...
Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
Phys.org / A WRAP for biology's greasiest problem
Embedded in the boundary between the inside and outside of each cell are membrane proteins. They act as first responders by sensing signals, regulating which molecules enter and leave the cell, and enabling cells to quickly ...
Phys.org / Beyond the dust: Families describe daily health challenges near the Salton Sea
A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children ...
Phys.org / MOF thin films reveal hidden dense packing, challenging decades of porous assumptions
Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
Phys.org / Austin neighborhood tap water tests uncover lead and arsenic in homes
For more than a decade, residents of Austin's Colony, a neighborhood in an unincorporated area of southeast Austin outside the city service area, have voiced concern about their tap water's intermittent discoloration and ...
Phys.org / Hunting behavior drives the evolution of spider eye arrangements, study finds
Vision shapes how many animals find food, avoid danger and navigate their world. In animals with two eyes, eye placement is often linked to lifestyle: predators such as lions tend to have forward-facing eyes that help them ...
