	Scientists find a universal gut microbiome pattern linked to colorectal cancer Researchers analyzed 6,779 stool microbiome profiles and 906 tissue samples to identify a colorectal cancer microbial signature that remained consistent across age groups, populations, and sequencing methods. The signature aligned with tumor-resident microbes, showed weaker detection for adenomas, and was inversely associated with dietary fiber intake.

	Faster biological aging may help explain rising cancer rates in younger adults A new study found that later birth cohorts showed greater biological aging, measured by systemic age-gap clocks. Greater biological aging was associated with higher early-onset solid cancer risk, especially lung, gastrointestinal, and uterine cancers.

			Experts urge neglected tropical disease status for ocular toxoplasmosis One third of the world's population is infected with the Toxoplasma parasite, which can cause ocular toxoplasmosis, an eye infection that can damage the retina and result in permanent vision loss.

			Could your birth characteristics influence colorectal cancer risk? A California study links birth and parental factors to early-onset colorectal cancer risk, highlighting male sex and Hispanic ethnicity as key contributors.

			Fiber blend relieves constipation and improves stool consistency A recent study found that a combination of dietary fibers effectively alleviated chronic constipation, enhancing bowel function and stool quality in adults.

	Scientists discover 70 existing drugs that block deadly hantavirus infections Researchers screened over 5,000 compounds and successfully pinpointed 70 existing drugs, including unexpected beta-lactam antibiotics, that effectively suppress Puumala orthohantavirus infection in human cells. This milestone drug-repurposing study provides an immediate, fast-tracked pipeline for developing the first approved treatments against life-threatening hantavirus diseases.

	AI and multiomics reveal how gut bacteria trigger colon cancer Over the past two decades, high‑throughput sequencing has dramatically expanded our understanding of the gut microbiome's composition.

	Lipid nanoparticles enhance immune response against lung cancer Researchers at the University of Arizona R. Ken Coit College of Pharmacy have developed a new strategy that helps the immune system recognize and attack lung cancer tumors more effectively.

	Probiotic metabolite found to suppress melanoma tumor growth in mice Immune checkpoint inhibitors like anti-PD-1 have transformed melanoma treatment, yet more than half of patients fail to respond or eventually develop resistance.

	Fatty liver disease fuels aggressive metastatic colorectal cancer spread Researchers at VIB and KU Leuven, with international partners, have uncovered how fatty liver disease can fuel the most aggressive form of metastatic colorectal cancer.

	Scientists uncover immune mechanisms driving rare gastrointestinal disorder A collaborative team led by Dr. Jingnan Li and Dr. Ji Li at Peking Union Medical College Hospital, together with Associate Professor Xiaohuan Guo at Tsinghua University and Academician Ye-Guang Chen at Tsinghua University School of Life Sciences, published a study in Volume 2, article number 28 of the journal Immunity & Inflammation on June 17, 2026.

	Targeting metabolic pathways could prevent relapse in KRAS-mutant cancers Our cells rely on tightly regulated signaling pathways to control when they grow, divide, and survive. When these regulatory systems are disrupted, cells can acquire the ability to grow uncontrollably and become cancerous.

	New project investigates gut microbiome for personalized bowel disease therapies The gut microbiome plays an important role in inflammatory bowel disease. In the research project MikrobiomProCheck, researchers are investigating how microbiome data can in future be used for diagnostics, disease monitoring and personalized therapies.

	New AI framework outperforms conventional biomarkers in predicting cancer survival Digestive system cancers, including hepatobiliary and gastrointestinal malignancies, remain a major global oncological burden. Although immune checkpoint inhibitors have changed the treatment landscape for some patients, their overall efficacy remains limited, with only about 15% to 30% of patients achieving durable clinical benefit.

	Altering gut microbes could improve immunotherapy responses in liver cancer Immune checkpoint blockade (ICB) has reshaped the treatment landscape for advanced hepatocellular carcinoma (HCC), offering new hope where few options existed.

	Nerve stimulation methods provide safe relief for oropharyngeal dysphagia Dysphagia, a severe comorbidity of many neurological diseases, often lacks targeted therapies. This critical review assessed the clinical effectiveness and safety of electrical stimulation of cranial nerves for treating dysphagia, including implantable (direct nerve stimulation), minimally invasive (pharyngeal electrical stimulation, PES), and non‑invasive (transcutaneous) approaches.

	Monoclonal antibody shows promise for treating acute respiratory distress syndrome Doctors have few options for patients who develop a life-threatening lung condition called acute respiratory distress syndrome, or ARDS.

	Aston University receives funding to develop unique cancer-fighting 'magnetobots' Aston University has been awarded €1.2m through the Marie Skłodowska-Curie Actions (MSCA) Staff Exchanges program for a project bringing together 18 partner organizations to develop unique cancer-fighting 'magnetobots'.
