Shared biological pathways may explain chronic fatigue across diseases

A shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD has been discovered by researchers at the University of East Anglia and Oxford BioDynamics.

Alcohol-linked cancer deaths doubled over three decades in America

Alcohol-attributable cancer deaths in the U.S. doubled between 1990 and 2023, a new study found. The study also revealed that alcohol-linked cancer deaths are not limited to older adults or liver cancer.

Why addiction researchers are paying closer attention to GLP-1 drugs

A Journal of Clinical Investigation Viewpoint highlights growing evidence that GLP-1 receptor agonists, particularly semaglutide, may reduce alcohol consumption and some other substance-related outcomes by acting on brain systems involved in reward, motivation, stress, and emotion. However, the authors caution that efficacy for substance use disorders is not yet firmly established and call for further research into optimal dosing, treatment duration, patient selection, mechanisms, and effects across different addictions.

Blocking a naturally occurring molecule reverses deadly lung disease in preclinical models

Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease.

New drug class shows major promise for shrinking nerve tumors

A scientist at Cincinnati Children's who has hunted for decades for ways to shrink the painful and disfiguring nerve tumors caused by neurofibromatosis type 1 (NF1) has made a new breakthrough in the quest.

Two scientists win Horwitz Prize for Rett syndrome breakthrough

Columbia University will award the 2026 Louisa Gross Horwitz Prize to Adrian Bird and Huda Zoghbi for their pioneering work on epigenetic regulation in the nervous system and its role in human neurological disease, particularly Rett syndrome.

Post-trauma mental health conditions increase future cardiovascular risks

Mental health conditions, such as posttraumatic stress disorder (PTSD), substance abuse, depression and anxiety, can develop after people experience trauma.

Study reveals why many patients fail to recover after stroke

A clot forms. Blood flow to the brain is blocked. Starved of oxygen, neurons begin to die.

Post-surgery immunotherapy may not benefit specific lung cancer patients

A new real-world observational study has found that adding adjuvant immunotherapy after surgery does not significantly improve survival outcomes in patients with resectable non-small cell lung cancer (NSCLC) who have already achieved a pathological complete response (pCR) following neoadjuvant chemoimmunotherapy.

Scientists develop lab-grown heart tissue model for heart failure

Scientists study the underlying causes of a disease or test new potential drugs in animal models or cells obtained from human biopsy specimens before clinical trials.

Giving immunotherapy before surgery boosts brain tumor treatment success

A team from UNIGE and HUG has shown that administering cell immunotherapy before surgery to remove a brain tumor is significantly more effective than administering it afterwards.

Bridging science and family story to understand schizophrenia origins

Twin studies have placed the heritability of schizophrenia at roughly eighty percent for decades. Concordance between identical twins, who share the entire genome, does not reach fifty percent. Both figures are well established, and they do not fit together comfortably.

Researchers discover dozens of genes tied to OCD and tic disorders

A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk for obsessive-compulsive disorder (OCD) and chronic tic disorders – providing what two researchers said is the most detailed biological understanding of how these conditions develop – and how they might eventually be treated.

Bacterial protein fragment corisin found to drive pulmonary fibrosis

A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell's quality-control system, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found in a new study.

Stay sharp after menopause: How aerobic exercise can improve key thinking skills

Regular aerobic exercise – the kind that gets your heart pumping – can improve important thinking skills called executive functions, and the benefits appear especially strong for women after menopause, according to Rutgers researchers.

Coffee’s link to Parkinson’s risk may depend on how your body handles caffeine

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metabolizer AA carriers, while higher intake was associated with increased risk among AC and CC carriers, although the observational findings do not establish causality and sex-specific patterns require cautious interpretation.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.
