Researchers develop pH and redox-sensitive systems to reduce immunotherapy toxicity

Although cancer immunotherapy has transformed treatment by harnessing the immune system to eliminate tumors, only a small subset of patients benefit. Many solid tumors remain "cold," characterized by poor immune cell infiltration and resistance to immune checkpoint blockade (ICB).

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

Thyroid hormone profiles provide critical prognostic clues for patients facing liver failure

Early and accurate prognostic assessment is crucial to prevent disease progression in liver failure. Thyroid hormones (THs), particularly triiodothyronine (T3), are key metabolic regulators and play an important role in liver regeneration. Liver failure is frequently complicated by non‑thyroidal illness syndrome (NTIS), characterized by low T3 with normal or slightly elevated TSH and T4.

Four-week diet intervention shifts biological aging markers

A short-term shift to whole-food, plant-based diets alters aging biomarkers in older adults, suggesting rapid physiological adaptation rather than age reversal.

Endometriosis increases risk of some birth defects in infants

Research indicates women with endometriosis may face a higher risk of congenital anomalies in infants, emphasizing the need for further investigation.

Timing of trauma strongly influences adult brain function and behavior

A research team from the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology), in collaboration with the IRCCS Istituto Giannina Gaslini in Genoa (Italy), has demonstrated that traumatic experiences occurring at specific stages of life - particularly from childhood through the early years following adolescence - have persistent effects on brain development and adult behavior.

Copper-based nanoplatform shows promise against metastatic tumor growth

What happens if cancer cells lose both their mitochondrial energy supply and their glycolytic backup system? This question is central to a new study published in Research by researchers from Northwestern Polytechnical University and collaborating institutions.

Advanced 3D heart models could transform cardiovascular drug discovery

Cardiovascular disease remains a leading global health burden, yet many preclinical systems still struggle to predict how candidate drugs will perform in the human heart.

Chromosome abnormalities may help cancer cells resist treatment and spread

A new study led by NYU Langone Health researchers found that cancer cells are better able to resist treatments when they have an abnormal number of chromosomes, which are DNA strands wound up in bundles that control which genetic instructions are followed in each cell type.

Methylmercury may harm metabolism beyond its known neurological effects

Methylmercury can accumulate in water environments and enter the food chain. Human exposure is of particular concern in communities affected by contaminated rivers, industrial pollution, artisanal gold mining and environmental disasters.

Obesity and Alzheimer’s linked through early metabolic disruptions

By 2030, the population in the United States aged 65 and older is expected to reach 71 million or about 20% of Americans. This growth is likely to increase the burden of age-related diseases, particularly Alzheimer's disease (AD), affecting about 1 in 9 adults over 65.
