In a study published in Cell on April 7, a research team led by Prof. LI Hanjie from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has revealed the presence of microglia in the peripheral nervous system (PNS) and identified their crucial role in regulating neuronal soma size throughout evolution. Microglia, also known as macrophages of the central nervous system (CNS), are specialized immune cells vital for brain health and injury response. ...

New research shows that the adult brain can generate new neurons that integrate into key motor circuits. The findings demonstrate that stimulating natural brain processes may help repair damaged neural networks in Huntington’s and other diseases.   “Our research shows that we can encourage the brain’s own cells to grow new neurons that join in naturally with the circuits controlling movement,” said Abdellatif Benraiss, PhD, a senior author of the study, which appears in the journal Cell Reports. “This discovery offers a potential new way to restore brain function and slow the progression ...

About The Study: In this cohort of Black women, living in disadvantaged neighborhoods was associated with a higher mortality from breast cancer, even after accounting for stage at diagnosis, treatments, and individual-level lifestyle factors. Community-level interventions to reduce environmental stressors and improve conditions in disadvantaged neighborhoods, including access to high-quality cancer care, may be critical to reducing racial disparities in breast cancer survival.

What if humanity's search for life on other planets returns no hits? A team of researchers led by Dr. Daniel Angerhausen, a Physicist in Professor Sascha Quanz's Exoplanets and Habitability Group at ETH Zurich and a SETI Institute affiliate, tackled this question by considering what could be learned about life in the universe if future surveys detect no signs of life on other planets. The study, which has just been published in The Astronomical Journal and was carried out within the framework of the Swiss National Centre of Competence in Research, PlanetS, relies on a Bayesian statistical analysis to establish the minimum number of exoplanets that should ...

CAMBRIDGE, MA -- Immune molecules called cytokines play important roles in the body’s defense against infection, helping to control inflammation and coordinating the responses of other immune cells. A growing body of evidence suggests that some of these molecules also influence the brain, leading to behavioral changes during illness. Two new studies from MIT and Harvard Medical School, focused on a cytokine called IL-17, now add to that evidence. The researchers found that IL-17 acts on two distinct brain regions — the amygdala and the somatosensory cortex — to exert two divergent effects. In the amygdala, IL-17 can elicit feelings of anxiety, while in the cortex it promotes ...

Home care cooperatives may be the key to alleviating the shortage of paid caregivers for older Americans, a new study suggests. The research, to be published in the peer-reviewed journal JAMA Network Open, found that participants in cooperatives experienced more respect, control, job support, and compensation than their counterparts in traditional care services. These factors may explain how cooperatives have achieved half the turnover rates of traditional agencies, which are plagued with high turnover and employee dissatisfaction. Millions of older adults will lack the support they need to safely age at home unless new strategies are developed and policies are ...

DETROIT (April 7, 025)— Nearly every person who dies by suicide visits a doctor’s office within a year of their death. A new body of research suggests that by adopting a specific protocol, health systems can reduce suicide rates among those patients by 25%. Researchers say the findings support comprehensive widespread adoption of a method audaciously named The Zero Suicide (ZS) Model, as suicide remains among the leading causes of death in the U.S. In 2022, 49,000 people died by suicide in the U.S. Suicide was the second ...

April 7, 2025, Mountain View, CA --  What if we spend decades building advanced telescopes to search for life on other planets and come up emptyhanded? A recent study led by ETH Zurich researchers including corresponding author and SETI Institute affiliate, Dr. Daniel Angerhausen, tackled this question, exploring what we can learn about life in the universe—even if we don’t detect signs of life or habitability. Using advanced statistical modeling, the research team sought to explore how many exoplanets scientists should observe and understand ...

Even in the case of uncomplicated infections, the body prepares itself early on for the possibility of a more severe course. A research team from the Technical University of Munich (TUM) and Helmholtz Munich has now uncovered this mechanism. The scientists showed that, right at the onset of mild illness, the body also produces special T cells previously known only from chronic, severe infections and tumors. There are different types of T cells in the body, all of which play a crucial role in the immune system. They fight pathogens and control the immune response. However, some subtypes become less effective ...

DALLAS, April 7, 2025 — On Saturday, April 5, the Howard University football team participated in an American Heart Association Hands-Only CPR (cardiopulmonary resuscitation) training to learn the correct rate and depth of CPR compressions to be confident and capable when faced with a cardiac emergency. According to American Heart Association data, 9 out of every 10 of people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of ...

Korea University College of Medicine (Dean Pyun Sung-Bom) and Yonsei University College of Medicine (Dean Choi Jae-Young) are kicking off a step-by-step global R& D network project in earnest to train future domestic physician-scientists.   Both colleges jointly operate the "Physician-scientist Network Expansion and Career Attraction Program" supported by the Ministry of Health and Welfare. At the same time, the colleges plan to promote the training of domestic physician-scientists and ...

Nearly one million people worldwide are plagued annually by cutaneous  leishmaniasis, a devastating skin infection caused by the Leishmania parasite. Predominantly affecting vulnerable populations in tropical and subtropical regions like North Africa and South America, this disease thrives in areas marked by malnutrition, poor housing and population displacement. Left untreated, it can lead to lifelong scars, debilitating disability and deep social stigma. Despite its global impact, there is no vaccine—and existing treatments are ineffective, toxic and difficult to administer.  A new study published in the journal Nature Communications on April 4, 2025, ...

New York, NY | April 7, 2025  – The Society for Health Communication and the Journal of Health Communication at the CUNY Graduate School of Public Health and Health Policy (CUNY SPH) have published its inaugural special issue: Successes and Failures: Everything We Learned from Health Communication Campaigns and Programs. It includes nine peer-reviewed research papers from health communication programs in the U.S. and around the world, featuring insights ...

COLUMBUS, Ohio – Have you ever gone to a store or a restaurant where the music was so annoying that you walked right out? Now imagine what it must be like for the employees.   In a new study, researchers found that when background music at a workplace is out of sync with what workers need to do their jobs, it can affect their energy, mood – and even performance.   “Music that doesn’t fit what an employee needs to feel energized, manage emotions, and focus on task can have a real negative impact,” said Kathleen Keeler, co-lead author of the study and assistant ...

Chestnut Hill, Mass (4/7/2025) – From Catholics to Evangelicals, a surprising 90 percent of Christian leaders in the U.S. believe in man-made climate change, yet most do not share that understanding with their congregants, according to a new report by Boston College researchers. The findings hold implications for how Christians might help address climate change, knowing their beliefs about the climate crisis align with their church’s values, according to Boston College Assistant Professor of Psychology Gregg Sparkman, senior author of the ...

CHAMPAIGN, Ill. — In a study that tracked explicit and implicit bias against stigmatized groups in 33 countries between 2009 and 2019, researchers found substantial reductions in explicit, self-reported bias against all categories of stigma they examined: age, race, body weight, skin tone and sexual orientation. The picture for implicit bias, which is sometimes described as “hidden” or “automatically revealed” bias, was more varied, however. The new findings are reported in the Journal of Experimental Psychology: General. “We used data from Project Implicit, a website established in the early 2000s that serves both as a venue to educate people ...

Illiberal pro-China narratives have gained traction in democratic countries like Japan, raising questions about how such narratives spread across political ideologies. Social media has become a key tool in this process, blurring the lines between traditional propagandists and their audiences. Ordinary citizens and astroturfing agents[1] within the target countries are now actively engaged in interpreting and disseminating propaganda, making participatory propaganda increasingly relevant in today’s information landscape. Although ...

A new artificial intelligence (AI) tool that can help interpret and assess how well treatments are working for patients with multiple sclerosis (MS) has been developed by UCL researchers. AI uses mathematical models to train computers using massive amounts of data to learn and solve problems in ways that can seem human, including to perform complex tasks like image recognition. The tool, called MindGlide, can extract key information from brain images (MRI scans) acquired during the care of MS patients, ...

The Last of Us is back on April 13 and this season is more realistic than ever. The trailer for the hit HBO series appears to show the “zombie fungus” cordyceps infecting humans by releasing air-borne spores, instead of through tentacles—closer to scientific reality. Spread the love (and spores) “Fungi love to make spores,” says Dr. Jim Kronstad, a professor and microbiologist at UBC’s Michael Smith Laboratories. Real-life cordyceps colonizes ant brains, causing the insect to climb to a high branch. The fungus then ...

Meeting the unmet need for a vaccine is the top priority for researchers studying Lyme disease, which infects about 476,000 people in the U.S. each year and can come with severe complications such as ongoing fatigue and joint issues. Vaccine developers have come close to success, but no human vaccine has yet been commercially viable.   After decades of trial and error, a promising new target is emerging—the Lyme bacterial protein CspZ, which the bacteria use to evade detection from the body’s immune system. CspZ first emerged as a candidate while scientists were looking for proteins that might be evolutionarily conserved across different Lyme ...

Statement Highlights: Mobile health technologies, such as wearable devices, mobile health apps and telehealth or remote coaching, have shown potential to help people start and maintain heart-healthy behaviors, such as eating a healthy diet, increasing physical activity, quitting smoking, monitoring sleep and more. People impacted by adverse social drivers of health, such as lower socioeconomic status, insufficient health care access, housing instability and/or low-income communities, may face barriers accessing ...

New York, NY [April 7, 2025]—As artificial intelligence (AI) rapidly integrates into health care, a new study by researchers at the Icahn School of Medicine at Mount Sinai reveals that all generative AI models may recommend different treatments for the same medical condition based solely on a patient’s socioeconomic and demographic background. Their findings, which are detailed in the April 7, 2025 online issue of Nature Medicine [DOI: 10.1038/s41591-025-03626-6], highlight the importance of early detection and intervention to ensure that AI-driven care is safe, effective, and appropriate for all. As ...
