Two patients who recently arrived in Brazil from African countries have been put in isolation after showing symptoms linked to Ebola, officials said, raising concerns about the deadly virus spreading beyond the African continent.

An outbreak of a rare type of Ebola virus has plagued Congo and Uganda, as cases outpace the response.

A novel pill helped people with advanced pancreatic cancer live longer, researchers reported Sunday, raising hopes of long-needed better treatments for one of the deadliest types of cancer.

Once confined to niche bodybuilding forums and hardcore gyms, unproven injectable peptides are now being openly marketed online to the average gym-goer by social media influencers—and regulators struggling to keep up.

Microplastics (MP) are the subject of intensive medical research, but little is yet known about their effects on the immune system. A study led by the Medical University of Vienna now shows that tiny particles of polyethylene terephthalate (PET) remain in the lungs of mice, can exacerbate respiratory tract inflammation and alter the immune responses associated with allergies.

Both too little and too much weight gain during pregnancy are associated with serious maternal and child health outcomes, including preterm birth, low birth weight, death, preeclampsia, and unplanned cesarean delivery. Women in low- and middle-income countries often face challenges such as food insecurity, poor diet, limited health care access, and inadequate micronutrient supplements, all of which contribute to unhealthy weight during pregnancy.

Researchers have discovered a new way that brain plasticity is controlled in early life, offering insight into the little-understood phenomenon of critical-period closure. In the months or years after birth, critical periods of learning in the brain are open, making the organ uniquely sensitive to information coming from the outside world. Experiences during this time can have a lasting impact on the brain by sculpting neural connections that persist into adulthood. As a child or young animal matures, this heightened period of brain plasticity ends as critical periods begin to close through mechanisms that remain largely unclear.

With the publication of the long-term data from the RELAZA2 study, a research program developed over many years by Dresden University Medicine for the treatment of leukemia patients, has reached an important milestone. The results demonstrate the potential of early, minimal residual disease (MRD)-guided therapy to delay or possibly prevent relapses. RELAZA2 is considered the world's first MRD-triggered prospective study in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). The study is published in the journal Blood.

Patients in London have received a pioneering new gene editing therapy that lowers "bad" cholesterol after a single infusion, as part of a study involving UCL scientists.

Online information about artificial intelligence (AI) and its impact on cancer research and treatment for both the patient and general-public audiences is limited, and the available webpages and videos are largely of low quality, difficult to read, and frequently omit risks of AI use, according to new research presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting and led by researchers from the Abramson Cancer Center (ACC) of the University of Pennsylvania and Penn's Perelman School of Medicine.
