Exploring how the maternal bond affects social processing in babies
Infants quickly recognize their mothers’ voices and maternal speech may influence how babies process unfamiliar social cues, such as the faces of strangers.
2025-11-10
(Press-News.org) 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 was happy or fearful did not affect these observations.
According to the researchers, these findings suggest that babies are quick to recognize their mothers’ voices. Furthermore, maternal speech may influence social processing in babies as they look at unfamiliar faces. Speaking on future experimental plans, says Jessen, “It’d be interesting to see how other sensory modalities like a mother’s smell or touch influence social processing in infants. How are babies combining sensory modalities to understand their social environment?”

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 ...

About The Study: U.S. individuals ages 1 to 19 are now more likely to die by firearm injury than any other cause. While this national shift occurred in 2019, Alaska had already flipped as early as 2004. Over the past 2 decades, more states flipped to firearm mortality as the predominant cause of death in this age group, including nearly half of the states in the most recent era reviewed.
