Prepandemic prevalence of dietary supplement use for immune benefits

JAMA Network Open

2025-02-11

(Press-News.org) About The Study: This study has 3 findings in a prepandemic context. First, approximately 1 in 9 U.S. residents used a dietary supplement for perceived immune benefits (supplements to prevent colds or boost the immune system), and such usage varied by several sociodemographic and health characteristics. Second, label claims related to immune benefits consistently appeared on over half of dietary supplements taken for perceived immune benefits. Lastly, the prevalence of dietary supplement use for perceived immune benefits due to a doctor recommendation and dietary supplement use exclusively for perceived immune benefits were both generally low, but both increased among older adults and individuals in poorer health.

Born to heal: Why babies recover, but adults scar, after heart damage

2025-02-11

Study in experimental animals reveals fundamental differences in how immune system drives healing based on age Newborn immune systems see, then eat dying cells, triggering production of bioactive lipids Findings open the door to developing treatments that could ‘reprogram’ adult immune systems CHICAGO --- Newborns with heart complications can rely on their newly developed immune systems to regenerate cardiac tissues, but adults aren’t so lucky. After a heart attack, most adults struggle to regenerate healthy heart tissue, leading ...

SNU researchers develop soft robot that crawls, climbs, and shape-shifts to move in new directions

2025-02-11

A new type of soft robot can crawl like a worm, climb cables, and suddenly snap into a completely different shape to move in a new direction—all controlled by a single air input. This breakthrough, developed by researchers at Seoul National University, introduces a fundamentally new way for soft robots to move and adapt to their surroundings. A Leap Forward in Soft Robotics Soft robots, made from flexible materials, are known for their ability to bend and stretch. However, until now, they struggled to precisely control motion and required complex ...

Mystery solved: New study reveals how DNA repair genes play a major role in Huntington's disease

2025-02-11

A new UCLA Health study has discovered in mouse models that genes associated with repairing mismatched DNA are critical in eliciting damages to neurons that are most vulnerable in Huntington's disease and triggering downstream pathologies and motor impairment, shedding light on disease mechanisms and potential new ways to develop therapies. Huntington’s disease is one of the most common inherited neurodegenerative disorders that typically begins in adulthood and worsens over time. Patients begin to lose neurons in specific regions of the brain responsible for movement control, motor skill learning, language and ...

Harvard Pilgrim Health Care Institute announces launch of Center for Sepsis Epidemiology and Prevention Studies (SEPSIS)

2025-02-11

Boston, MA – The Harvard Pilgrim Health Care Institute is proud to announce the launch of the Center for Sepsis Epidemiology and Prevention Studies (SEPSIS). This pioneering center of excellence is dedicated to advancing understanding, prevention, and management of sepsis, a life-threatening condition caused by a dysregulated immune response to infection. The SEPSIS Center will be led by Dr. Chanu Rhee and Dr. Michael Klompas, internationally recognized leaders in sepsis surveillance, prevention, treatment, and policy. Both serve as faculty at Harvard Medical School and the Harvard Pilgrim Health Care Institute and bring a wealth of expertise and a shared commitment ...

New perspectives for personalized therapy of brain tumors

2025-02-11

Scientists from the German Cancer Research Center (DKFZ) and ShanghaiTech University have developed an innovative method for growing brain tumors of individual patients in the laboratory that mimic the original structure and the molecular property of the parental tumor as closely as possible. Drug tests in this model were found to correlate very well with actual patient responses, making it a valuable method for investigating therapies. Tumor organoids, i.e. mini-tumors grown from surgical material in the culture dish, ...

IEEE researchers provide mathematical solutions to study 2D light interaction in photonic crystal lasers

2025-02-11

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or ‘optical feedback’. Once the light has achieved desirable optical gain, laser diodes release it as powerful laser beams. Photonic crystal surface-emitting lasers (PCSELs) are advanced laser diodes where the optical gain is typically distributed laterally to the propagating light within a photonic crystal (PC) structure. They differ from traditional lasers by separating gain, feedback, and emission functions, offering scalable single-mode power and innovative ...

New joint project to investigate quantum repeaters designed to provide for secure quantum communication networks of the future

2025-02-11

There are reports of IT sabotage, cyber espionage, and other acts of hybrid warfare almost every day. Communication networks based on quantum physics could help eliminate threats of this kind. Researchers throughout Germany have already been working on developing those networks based on quantum repeaters for several years. In January 2025, the German Federal Ministry of Education and Research (BMBF) started funding a new research project, entitled Quantenrepeater.Net (QR.N), which aims to demonstrate the viability of quantum repeaters over test networks outside the protected lab environment. The BMBF will be providing a total of EUR 20 million over three years. ...

Microbiome as a potential key to better treatment: Clinical study on new therapy for Crohn's disease

2025-02-11

A special liquid diet, known as exclusive enteral nutrition, is an essential therapy for Crohn's disease. Patients consume only this formula for six to eight weeks, completely avoiding solid foods. However, the exact reasons why this is helpful were previously unclear. Researchers at the Technical University of Munich (TUM) and the LMU University Hospital Munich have now been able to decipher the mechanism behind this dietary therapy. Based on these results, they are launching a clinical study combining dietary therapy with faecal microbiome transfer to further enhance ...

AI predicts the precursor materials needed for material synthesis

2025-02-11

Researchers in Korea have developed a technology that automatically identifies the necessary precursor materials to synthesize specific target materials. A joint research team led by Senior Researcher Gyoung S. Na from the Korea Research Institute of Chemical Technology (KRICT) and Professor Chanyoung Park from the Korea Advanced Institute of Science and Technology (KAIST) has developed an AI-based retrosynthesis methodology that predicts the required precursor materials solely based on the chemical formula of the target material without expensive material descriptors ...
