Preclinical support for using psychedelics to treat alcohol use disorders
Researchers discover a mechanism in female mice that explains how psilocin, the active compound of a psychedelic found in mushrooms, may reduce alcohol use
2025-11-10
(Press-News.org) A psychedelic found in mushrooms is emerging as a potential treatment for alcohol use disorders. This possibility is due to a compound the body converts the psychedelic into called psilocin, but psilocin’s mechanisms remain unclear. Researchers, led by Sarah Magee and Melissa Herman at University of North Carolina at Chapel Hill, explored whether psilocin targets neurons in the central amygdala involved in emotional processing and stress to alter alcohol use in their JNeurosci paper. Herman emphasizes that preclinical work like this is necessary for filling gaps in knowledge about drug mechanisms, especially in the field of psychedelic research.
Focusing on female mice because they drink more alcohol than male mice, the researchers discovered that psilocin dampened the activity of these neurons following long-term alcohol exposure. This decrease in activity was associated with less alcohol drinking during drug exposure, though drinking was restored in later sessions. These observations also occurred in mice with less severe alcohol exposure, supporting clinical work showing that psychedelics may help improve issues with emotional processing and stress across a range of psychiatric disorders.
According to the researchers, these findings may shape interpretations of clinical studies on psychedelic treatments. Elaborating on their findings, says Herman, “It makes sense that dampening this neuron population reduces drinking because increased activity in these neurons is associated with alcohol use disorders. These neurons also play a role in depression and anxiety, which psychedelics are also showing promise at treating, so our work provides some mechanistic insight in those contexts, too.”

In a new JNeurosci paper, Sarah Jessen and colleagues, from the University of Lübeck, explored how infants track their mothers’ voices compared to unfamiliar voices. The researchers also explored whether this vocal processing affects how babies process new faces.
Brain recordings of babies around 7 months old showed that they were far more attuned to the voices of their mothers than strangers. Additionally, neural tracking of unfamiliar faces was stronger when babies heard a stranger’s voice compared to their mother’s voice at the same time. Whether a face ...

In a new JNeurosci paper, Kahori Kita and colleagues at Johns Hopkins University explored how people switch between intuitive motor skills they know and newly learned movement patterns.
Study volunteers frequently made errors switching between more innate movements and new ones. These errors were largely because people persistently stuck to the movement patterns they used before the switch. Notes Kita, “People made similar errors when switching from the intuitive to the new skill, as when switching from the new skill to the intuitive one.” A second group of people learned two new movement-based skills. It was initially even more difficult for these ...

A new native bee species with tiny devil-like “horns” named Megachile (Hackeriapis) lucifer has been discovered in Western Australia’s Goldfields, highlighting how much remains unknown about Australia’s native pollinators.
The striking new bee was found during surveys of a critically endangered wildflower Marianthus aquilonarius that grows only in the Bremer Range region, which is between the towns of Norseman and Hyden.
Lead author Curtin Adjunct Research Fellow Dr Kit Prendergast, from the Curtin School of Molecular and Life Sciences, said the female bee’s unusual ...

ST. LOUIS, MO, November 10, 2025 - A new collaborative research team of plant scientists led by Ru Zhang, PhD, associate member, Danforth Plant Science Center has been awarded new funding from the National Science Foundation to investigate how photosynthetic cells retain “heat stress memory” (HSM), a key adaptive mechanism that could help future crops withstand intense and frequent heat waves.
Photosynthesis, the process by which plants convert sunlight into energy, is the key driver of plant growth ...

Researchers at the University of California San Diego School of Medicine have developed a new approach for identifying individuals with skin cancer that combines genetic ancestry, lifestyle and social determinants of health using a machine learning model. Their model, more accurate than existing approaches, also helped the researchers better characterize disparities in skin cancer risk and outcomes.
Skin cancer is among the most common cancers in the United States, with more than 9,500 new cases diagnosed every day and approximately ...

November 10, 2025— Adults who experience poverty-level family income—whether sustained or intermittent—over two decades spanning young to mid-adulthood face a significantly higher risk of dying prematurely than those who are never in poverty, according to new research led by Columbia University Mailman School of Public Health. A companion study by the same research team finds that rising unsecured debt—such as credit card debt not tied to an asset—may be one mechanism linking early-life financial hardship to ...

NEW YORK, NY, November 10, 2025 – An interdisciplinary team of scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) has unveiled a groundbreaking conceptual model and integrative monitoring framework designed to reveal how climate change is stressing life across the planet. Their study, published this week in Cell Reports Sustainability, introduces the concept of the Climate BioStress model and proposes the adoption of an integrative Climate BioStress Sentinel System (CBS3), which could transform how researchers, policymakers, ...

Few primary care practices are designed for the timely detection of Alzheimer’s disease and related dementias. The limited time that primary care clinicians are able to spend with patients, the need to focus on the health problems which brought the patient to the clinic, as well as the stigma of Alzheimer’s disease and dementia are major reasons for lack of recognition of the condition.
Researchers have demonstrated that a fully digital artificial intelligence zero-cost method for detecting dementia can be scaled across primary care clinics without ...

PROVIDENCE, R.I. [Brown University] — A federally funded clinical trial to evaluate an intervention to prevent suicides among people recently released from jail reduced suicide attempts by 55%.
That’s according to a new study in JAMA Network Open led by researchers from Brown University and Michigan State University.
In the United States, one in five adults who attempts suicide has spent at least one night in jail in the year prior. With more than 10 million admissions per year and many stays of just a few days, jails touch a significant number of people at high risk for suicide who are not well connected with other support services. This ...
