The devastating impacts of marine heatwaves extend far beyond dying coral reefs and declining fisheries, with new research warning these extreme ocean warming events are posing a growing threat to humans' physical and mental health.

A two-year cohort study of 428 people exposed to H5N1-infected birds in England found fewer than 1% met criteria for infection, with no severe disease or secondary human transmission. The findings support continued PPE use, biosecurity, and targeted surveillance while highlighting challenges around occupational exposure, mucosal contamination, and pandemic preparedness.

Researchers at National Jewish Health and partner institutions discovered specific changes in immune cells in the lungs of people with sarcoidosis.

A new research paper was published in Volume 17 of Oncotarget on August 7, 2026, titled "Delayed growth of SK-ES-1 Ewing sarcoma tumor xenografts is associated with reduced Trk and IGF1R pathway markers."

Scientists at St. Jude Children's Research Hospital created a single-cell atlas of a key class of spinal neurons involved in motor coordination. From that resource, they identified a small subgroup of interneurons associated with the speed of rhythmic movements such as walking.

Phthalates, which are chemicals found in plastics, personal care products and hundreds of other consumer goods, may contribute to high blood pressure in pregnant women, according to a study published in the Journal of the Endocrine Society.

A new study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that while traditional pathological features used to classify aggressive prostate cancer -such as high-grade disease, cancer extending outside the prostate and cancer involving the seminal vesicles- after surgery can help identify patients who are more likely to have worse outcomes, they do not predict who will benefit more from adding hormone therapy to postoperative radiation.

Humans trust dogs to help find missing people and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.

An international study finds that older adults who have strong beliefs about how other seniors should behave also report having more memory problems themselves.

Researchers at the University of Colorado Anschutz Cancer Center have identified a previously unknown metabolic weakness in the stem cells that drive high-risk myelodysplastic syndromes (MDS), a discovery that could lead to more targeted treatments for this aggressive blood cancer.

Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown signalling pathway, opening new possibilities for treating advanced fatty liver disease.

Baylor College of Medicine today announced that a new research agreement with United Therapeutics Corporation, a public benefit corporation, will provide up to $5 million a year for five years to establish the Baylor College of Medicine Center for Xenoliver Transplantation and Immunomodulation (XTI), dedicated to advancing scientific understanding of xenoliver transplantation.

Researchers at Weill Cornell Medicine have uncovered how a key Parkinson's protein called LRRK2 shifts between inactive and active forms, revealing the structural changes that enable certain mutations to push the protein into an overactive state.

A team led by researchers from the German Cancer Research Center (DKFZ), the HI-STEM Stem Cell Institute, and Medical Clinic V at Heidelberg University Hospital (UKHD) has characterized T cells in the bone marrow in cases of multiple myeloma and acute myeloid leukemia: A specific group of tumor-reactive T cells can recognize and, in principle, fight cancer cells, but is often not sufficiently activated.

A new nationwide study finds antiviral treatment is linked to fewer intensive care unit (ICU) admissions and shorter hospital stays for children hospitalized with influenza.

A new study led by researchers at the University of Pittsburgh found that women living in socially vulnerable communities face a 20% higher risk of death after an ovarian cancer diagnosis compared with women living in less vulnerable communities.

The brain evidently can regenerate itself better than previously assumed after injuries or certain autoimmune diseases.

A joint research team led by Professor Sungsu Park of Sungkyunkwan University and Professor Sun-Ha Paek of Seoul National University College of Medicine has demonstrated for the first time that the sequence in which immune cells interact with cancer cells can critically influence the therapeutic response in glioblastoma.

Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases.

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.
