Medical Xpress / A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin
In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...
Phys.org / Optical design unlocks direct Raman detection of ångström-scale ultrathin molecular layers at interfaces
Conventional spontaneous Raman spectroscopy of interfacial molecules typically requires plasmonic or electronic enhancement, limiting accessible systems. A nonlinear coherent Raman method now enables direct, high sensitivity ...
Phys.org / This new tool makes AI's role in student writing visible
Generative artificial intelligence (AI) has transformed college writing. As paper drafts are increasingly co-written with AI, professors are left wondering not whether students are using AI, but how. A 2025 AI in Education ...
Science X / Your dreams are doing far more than replaying your day, and this study shows why
Why do dreams sometimes feel vivid and immersive, while at other times they seem fragmented or difficult to interpret? A new study conducted by researchers at the IMT School for Advanced Studies Lucca provides new insights ...
Phys.org / Investigating the disordered heart of glass
Recent research led by the University of Trento reveals that fundamental atomic vibrations remain unchanged also in ultra-stable glasses. This discovery advances the decade-long debate on the physics of disorder and opens ...
Phys.org / Why real-time teamwork dashboards can backfire instead of improving collaboration
As digital tools become more common in teamwork, many organizations hope they can help teams collaborate more effectively. But a new study suggests that some uses of tools—such as providing real-time feedback on collaboration ...
Medical Xpress / How the brain recovers from noise-induced damage
When a sound stops, our auditory system generates a precise "offset" response that marks this moment. This enables the brain to measure the duration of a sound and detect brief gaps in communication signals, such as in conversations. ...
Medical Xpress / GLP-1 reduces heavy drinking days in treatment seeking people with alcohol use disorder and obesity, finds small trial
A trial of 108 adults with obesity seeking treatment for alcohol use finds a once-weekly semaglutide injection reduced heavy drinking days in the past 30 days by an average of roughly 12 days, 50% higher than the eight-day ...
Phys.org / Hold your nose and don't stop for a selfie: Why getting up close to a beached whale is a really bad idea
The beaches of Sydney's Royal National Park have been disrupted by a pungent odor. And its source is drawing in more than just seagulls.
Medical Xpress / Children may be born with two complex cognitive functions already established, research reveals
A new study is the first to show that two of our most sophisticated cognitive functions, using and understanding language and being able to sense how other people feel, have distinct origins in the brain in young children—matching ...
Phys.org / New microscope reveals previously hidden differences in photosynthetic light-harvesting antennae
How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient absorption microscope with sensitivity approaching the single-molecule level.
Phys.org / Aligned cells may explain why some wounds heal faster than others
Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model developed by researchers at the University of Bristol. The study, published in Physical Review Letters, builds on previous ...
