New protein interaction map sheds light on how brain cell communication breaks down in Alzheimer’s disease
2025-09-25
New York, NY [September 25, 2025] — A new study led by the Icahn School of Medicine at Mount Sinai offers one of the most comprehensive views yet of how brain cells interact in Alzheimer’s disease, mapping protein networks that reveal communication failures and point to new therapeutic opportunities.
Published online in Cell on September 25, the study analyzed protein activity in brain tissue from nearly 200 individuals. The researchers discovered that disruptions in communication between neurons and supporting brain cells called glia—specifically astrocytes and microglia—are ...
AGU and AMS invite proposals for the U.S. Climate Collection
2025-09-25
The American Geophysical Union (AGU), the world’s largest association of Earth and space scientists, and the American Meteorological Society (AMS), the professional society for atmospheric and related sciences and services, invite contribution proposals for a joint special collection of research articles called the “U.S. Climate Collection: Informing Assessment of Risks and Solutions.”
This collaborative effort, first announced earlier this year in the wake of the dismissal of the Sixth National Climate Assessment (NCA) authors, aims to publish ...
Advances in iron-based Fischer-Tropsch synthesis with high carbon efficiency
2025-09-25
Fischer-Tropsch synthesis (FTS) is an important technology for converting carbon-rich resources such as coal, natural gas, and biomass into clean fuels and high-value chemicals through synthesis gas. Iron-based catalysts are widely used in industrial applications due to their low cost and strong adaptability, especially for syngas derived from coal or biomass with low H2/CO ratios. However, the catalytic process is complicated by frequent phase transformations among metallic iron, iron oxides, and iron carbides, which ...
NFL mascots inspire kids to PLAY 60 daily for better health
2025-09-25
DALLAS, Sept. 25, 2025 — Six NFL (National Football League) club mascots are stepping up to inspire kids to move more to support mental and physical health. These NFL mascots are serving as members of the inaugural NFL PLAY 60 Ambassador class supporting the NFL and the American Heart Association’s work to help kids achieve a minimum of 60 minutes of moderate-to-vigorous physical activity each day. Rooted in the American Heart Association’s physical activity guidelines, NFL PLAY 60 supports the evidence-based guidance that students who are active learn better, focus more, think more ...
Biomarker discovery for metabolic dysfunction-associated steatotic liver disease utilizing Mendelian randomization, machine learning, and external validation
2025-09-25
Background and Aims
The causal biomarkers for metabolic dysfunction-associated steatotic liver disease (MASLD) and their clinical value remain unclear. In this study, we aimed to identify biomarkers for MASLD and evaluate their diagnostic and prognostic significance.
Methods
We conducted a Mendelian randomization analysis to assess the causal effects of 2,925 molecular biomarkers (from proteomics data) and 35 clinical biomarkers on MASLD. Mediation analysis was performed to determine whether clinical biomarkers mediated the effects of molecular biomarkers. The association ...
Psychological comorbidity in patients presenting to the emergency department with low-risk chest pain and anxiety
2025-09-25
INDIANAPOLIS -- Chest pain ranks as the second most common reason for emergency department (ED) visits, making it a key concern for patients and doctors. However, 80 percent of these cases are considered low-risk and not related to heart disease, and for these patients, anxiety and panic disorders are frequent diagnoses.
A new study led by the Indiana University School of Medicine and Regenstrief Institute researchers shows that many patients who visit the ED with low-risk chest pain might benefit more from treatment for underlying psychological conditions than from extensive cardiac testing.
Anxiety is not only common among low-risk ...
New study reveals subway station fungal communities
2025-09-25
Key Points:
Microbiologists have previously studied the bacterial species found in subway stations, but fungi have often been overlooked.
An international team of researchers collected monthly samples from subway stations in Beijing and found high fungal diversity, mostly non-pathogenic. Some opportunistic pathogens were also detected.
Fungal communities were observed to vary significantly by season and station types.
The work could guide better strategies for air quality control in urban transit systems.
Washington, D.C. — Subways don’t just bring people together. They’re also ...
Adding a lookup step makes AI better at assigning medical diagnosis codes
2025-09-25
New York, NY [September 25, 2025]— A new study from researchers at the Mount Sinai Health System suggests that a simple tweak to how artificial intelligence (AI) assigns diagnostic codes could significantly improve accuracy, even outperforming physicians. The findings, reported in the September 25 online issue of NEJM AI [DOI: 10.1056/AIcs2401161], could help reduce the time doctors spend on paperwork, cut billing errors, and improve the quality of patient records.
“Our previous study showed that even the most advanced AI could produce the ...
NSF supports study of how isolation and dopamine impact the brain
2025-09-25
Scientists know that social isolation can alter brain structure and lead to the breakdown of myelin, the fatty coating that insulates nerve fibers in the brain. But they don’t yet know exactly how or why it happens.
A new, five-year study, supported by the National Science Foundation, investigates the potential mechanisms that drive the process. “We’re looking at the role of dopamine in regulating changes in myelin caused by social isolation,” said study leader Leora Yetnikoff, a professor of Biology and a member of the CUNY Neuroscience Collaborative at the CUNY Graduate Center, and a professor of psychology at the College of Staten Island.
Yetnikoff ...
