And it’s not from Neuralink.
Recently, Semafor received an extraordinary iMessage. It was from Rodney Gorham, a paralyzed ALS patient, and he had sent it directly from his brain. Gorham has a brain implant called Stentrode. Unlike previous generations of brain-computer interfaces, the Stentrode, from the neurotechnology company Synchron, can be implanted without invasive brain surgery. But… what *are* brain-computer interfaces? How do they work? And where is this novel technology going?
A specific brain mechanism modulates how animals respond empathetically to others’ emotions. This is the latest finding from the research unit Genetics of Cognition, led by Francesco Papaleo, Principal Investigator at the Istituto Italiano di Tecnologia (IIT – Italian Institute of Technology) and affiliated with IRCCS Ospedale Policlinico San Martino in Genova. The study, recently published in Nature Neuroscience, provides new insights into psychiatric conditions where this socio-cognitive skill is impaired, such as post-traumatic stress disorder (PTSD), autism, and schizophrenia.
Psychological studies have shown that the way humans respond to others’ emotions is strongly influenced by their own past emotional experiences. When a similar emotional situation—such as a past stressful event—is observed in another person, we can react in two different ways. On one hand, it may generate empathy, enhancing the ability to understand others’ problems and increasing sensitivity to others altered emotions. On the other hand, it may induce self-distress resulting into an avoidance towards others.
The research group at IIT has demonstrated that a similar phenomenon also occurs in animals: recalling a negative experience strongly influences how an individual responds to another who is experiencing that same altered emotional state. More specifically, animals exhibit different reactions only if the negative event they experienced in the past is identical to the one they observe in others. This indicates that even animals can specifically recognize an emotional state and react accordingly even without directly seeing the triggering stimuli.
The use of antidepressants during pregnancy significantly increased the risk of a child experiencing functional constipation—a common DGBI that may be painful—during their first year of life. “After adjusting for covariates, SSRI/SNRI exposure was associated with an over 3-fold increased risk for functional constipation,” the investigators wrote.
“We found that, at the age of one, 63% of children exposed to antidepressants during pregnancy experienced constipation, compared with 31% of children whose mothers did not take medication,” said study co-author Larissa Takser, MD, professor of pediatrics at the Université de Sherbrooke in Québec. “This finding suggests a potential connection between serotonin levels in utero and gut development, and opens new doors to examine SSRI properties not previously studied.”
The investigators’ collective findings point to a promising avenue of future studies: the gut epithelium as a new and potentially safer target for treating mood disorders, particularly for pregnant women. “Together, these data define a novel potential mechanism for gut-brain communication and identify intestinal epithelial 5-HT as a new and potentially safer therapeutic target for mood regulation,” the authors stated.

Quantum sensors, a cutting-edge technology capable of detecting subtle signals from the human body, could soon transform how diseases are diagnosed and monitored, according to a report from the Quantum Economic Development Consortium (QED-C).
The report outlines how quantum sensing tools — ranging from diamond-based detectors to optically pumped magnetometers — offer unprecedented sensitivity compared to traditional medical devices. These sensors could enable earlier diagnoses for diseases like Alzheimer’s, provide better imaging of fetal development, and even analyze the microbiome in real time.
“Improved sensors could impact diverse aspects of biomedicine,” the report states. “For example, quantum sensors offer the possibility of significantly more efficient and accurate medical diagnoses for patients, thanks to their increased sensitivity and novel options for form factor. These attributes could enable quantum sensors to collect vast amounts of data about patients and medical conditions, and thus facilitate drug and treatment development and earlier diagnosis of disease. The advantages of quantum sensors encourage new ideas about solutions, quantum use cases, and business models across the biomedical industry — from prenatal care to cancer detection and treatment.”
Nature Medicine asks leading researchers to name their top clinical trial for 2025, from gene therapies for prion disease and sickle-cell disease to digital tools for cancer and mental health.
Research from Washington University shows that glioblastoma, a type of brain cancer, has its own internal clock that synchronizes with the host’s circadian rhythms to optimize its growth by responding to daily hormone releases like cortisol.
Targeting these circadian signals in treatment slowed tumor growth significantly in both lab and animal studies. This synchronization could explain the mixed effects of dexamethasone, a common treatment, depending on the timing of its administration. The study highlights the potential of chronotherapy, aligning treatment with the body’s natural rhythms, to improve cancer outcomes.

Understanding Senescence in Brain Aging and Alzheimer’s Disease
Guest Editors Drs. Julie Andersen and Darren Baker, Associate Editor Dr. Anna Csiszar and Editor-in-Chief Dr. Zoltan Ungvari, and the editorial team of GeroScience (Journal of the American Aging Association; 2018 Impact Factor: 6.44) invite submission of original research articles, opinion papers and review articles related to research focused on understanding the role of senescence in brain aging and in Alzheimer’s disease. Senescent cells accumulate in aging and pathological conditions associated with accelerated aging. While earlier investigations focused on cellular senescence in tissues and cells outside of the brain (e.g. adipose tissue, dermal fibroblasts, cells of the cardiovascular system), more recent studies started to explore the role of senescent cells in age-related decline of brain function and the pathogenesis of neurodegenerative disease and vascular cognitive impairment. This call-for-papers is aimed at providing a platform for the dissemination of critical novel ideas related to the functional and physiological consequences of senescence in diverse brain cell types (e.g., oligodendrocytes, pericytes, astrocytes, endothelial cells, microglia, neural stem cells), with the ultimate goal to identify novel targets for treatment and prevention Alzheimer’s disease, Parkinson’s disease and vascular cognitive impairment. We welcome manuscripts focusing on senescent-cell-targeting mouse models, the role of paracrine senescence, senescence pathways in terminally differentiated neurons, the pleiotropic effects of systemic senescence, the role of senescence in neuroinflammation and the protective effects of senolytic therapies. We are especially interested in manuscripts exploring the causal role of molecular mechanisms of aging in induction of cellular senescence as well as links between lifestyle (e.g., diet, exercise, smoking), medical treatments (e.g. cancer treatments), exposure environmental toxicants and cellular senescence in the brain. We encourage submission of manuscripts on developing innovative strategies to identify and target senescent cells for prevention/treatment of age-related diseases of the brain. Authors are also encouraged to submit manuscripts focusing on translational aspects of senescence research.
All manuscripts accepted from this Call for Papers will be included in a unique online article collection to further highlight the importance of this topic. All manuscripts should be submitted online here: https://www.editorialmanager.com/jaaa/default.aspx.
A study in mice has found that maternal gut microbiome composition during pregnancy has long-term effects on offspring stem cell growth and development. The researchers, headed by Parag Kundu, PhD, at the Institut Pasteur of Shanghai-Chinese Academy of Sciences, found that treating pregnant mice with the common gut microbe Akkermansia muciniphila resulted in offspring that had more active stem cells in both the brain and intestinal tract. As a result the offspring were less anxious and recovered quicker from colitis, and these differences were still evident at 10 months of age.
The team showed that Akkermansia muciniphila impacted stem cell growth by altering the abundance of other gut microorganisms and increasing the microbial production of metabolites that cross the placenta and induce stem cell growth and proliferation. Exposing offspring to the bacterium after birth did not result in the same stem cell activation.
“This is a major advancement in developing microbiota-based intervention strategies to improve child health,” said Kundu, who is senior author of the team’s published paper in Cell Stem Cell, titled “Maternal gut microbiota influence stem cell function in offspring.” In their report the team stated, “These results suggest a fundamental role of the maternal microbiome in programming offsprings’ stem cells and represent a promising target for interventions.”
