Beyond histamine: Study links intestinal leukotrienes to oral anaphylaxis in mice

University of Jaén investigators report significant reductions in anxiety and increased life satisfaction in adults through laughter therapy across 33 clinical trials.

The U.S. Food and Drug Administration (FDA)'s top vaccine regulator is returning to his post less than two weeks after the White House had him ousted.

The R21/Matrix-M malaria vaccine generates nearly identical antibodies as those following a natural infection, helping explain why the vaccine confers such strong protection against the earliest life stage of malaria parasites, according to research published in the Journal of Experimental Medicine.

A new study by researchers at Unity Health, Sunnybrook Health Sciences Center and the University of Toronto has found that patients with a diabetes-related eye condition who are male, Black or Hispanic, or live farther from a treatment center are more likely to miss follow-up appointments, putting them at greater risk of vision loss.

Researchers at Boston University Chobanian & Avedisian School of Medicine have built an artificial intelligence (AI) tool that can accurately predict key signs of Alzheimer's disease—such as the presence of sticky proteins called amyloid beta and tau—using common and less expensive tests like brain scans, memory checks and health records. The findings appear online in the journal Nature Communications.

Oxytocin promotes social behaviors and helps maintain relationships. But clinical trials in patients with autism show variability in how consistently oxytocin improves these behaviors.

A cancer drug could enhance how patients respond to chemotherapy even in treatment-resistant tumors. The drug works by disarming a key defense mechanism that tumors use to protect themselves from treatment. In preclinical models, it has already shown promise in making chemotherapy-resistant cancers more responsive to therapy.

The search for new ways to treat malaria—a disease that kills some 600,000 people a year, most of them children in Sub-Saharan Africa—may have just gotten a boost.

Sensitive teeth need tough toothpaste, but technology can also help. Researchers at the Indian Institute of Science (IISc) in collaboration with deep-tech startup Theranautilus have now engineered CalBots—magnetic nanobots that can penetrate deep into dentinal tubules, which are tiny tunnels in teeth that lead to nerve endings. These CalBots can then form durable seals for worn enamel, offering lasting relief from sensitivity in just one application. The study is published in Advanced Science .

Treatment with interferon or with glatiramer acetate? This question arises for many patients who receive a diagnosis of multiple sclerosis (MS) for the first time. Until now, the choice between the two could practically be made at random: both preparations are considered established basic therapies, both have relatively low side effects and both are relatively well tolerated. And, as with all immunomodulatory therapies, both do not help all people equally well. However, thanks to a study led by the University of Münster, there is now a clear criterion for choosing the medication.

Cornell researchers have developed an implant system that can treat type 1 diabetes by supplying extra oxygen to densely packed insulin-secreting cells, without the need for immunosuppression. The system could also potentially provide long-term treatment for a range of chronic diseases.

If the brain no longer responds properly to insulin (insulin resistance), this can lead to weight gain, diabetes, and Alzheimer's disease. Researchers at the German Center for Diabetes Research (DZD) in Potsdam and Tübingen have discovered small chemical modifications to genetic material (epigenetic changes) in the blood that indicate how well the brain responds to insulin. These markers could help to detect insulin resistance in the brain by means of a simple blood test. The findings are published in Science Translational Medicine.

Building upon the success of the first in utero brain surgery for vein of Galen malformation (VOGM) reported in 2023, new data published in JAMA provides further evidence for the potential use of fetal embolization for this condition.

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London in partnership with the Mayo Clinic and UNEEG medical, has found that an electronic device placed under the scalp is an effective and feasible means of accurately tracking epilepsy.

The human brain ages less than thought and in layers—at least in the area of the cerebral cortex responsible for the sense of touch. Researchers at DZNE, the University of Magdeburg, and the Hertie Institute for Clinical Brain Research at the University of Tübingen came to this conclusion based on brain scans of young and older adults in addition to studies in mice.

Research by sports scientists reveals that high-performance athletes face unique mental health challenges despite the well-established benefits of physical activity for depression prevention and treatment.

Artificial intelligence (AI) can help emergency department (ED) teams better anticipate which patients will need hospital admission, hours earlier than is currently possible, according to a multi-hospital study by the Mount Sinai Health System.

Approximately 70% of incarcerated youth in the United States have a mental disorder. The challenges in this population are profound—about 30% report suicidal thoughts, 12% have attempted suicide and 25% experience solitary confinement, a condition strongly associated with increased suicide risk. Depression is also widespread, affecting 10% to 25% of youth with moderate to severe symptoms.
