Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.

Cancer drug eliminates HIV-infected cells in animal model study

Emory University researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

New method based on human blood simplifies mRNA drug development

mRNA-based drugs are emerging as the drug of the future for a wide range of diseases, but they are difficult and time-consuming to develop.

Laser-based therapy shows promise against dangerous abdominal infections in children

Children whose appendix has burst often develop serious abdominal infections that are hard to treat and increasingly resistant to antibiotics.

Could the type of fiber children eat matter for their developing gut microbiome?

A recent study found that different dietary fibers can shape the composition and activity of the gut microbiome during early childhood, with xyloglucan, arabinoxylan, and pectin increasing short-chain fatty acid production in laboratory fermentation experiments. Some fibers also supported gut barrier measures and altered inflammatory responses, while observational data linked higher pectin intake with greater microbial diversity in young children.

Egg yolk peptides protect brain cells from oxidative stress

As the human lifespan increases, so too does the risk of developing neurological disorders such as Parkinson's disease, Alzheimer's disease, anxiety and depression.

Nanoparticles regenerate neurons and improve cognition in Alzheimer’s mice

The adult human brain has limited capacity to repair or regenerate neurons lost to Alzheimer's disease, the most common type of dementia.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

New battery-free pacemaker harvests power from every heartbeat

A team of University of Wisconsin–Madison researchers has developed an implantable, battery-free pacemaker that's charged by a patient's heartbeat.

New optical control platform blocks and restores neural signaling

DGIST (President Kunwoo Lee) announced that a research team led by Professor Ji Won Um of the Center for Synapse Diversity and Specificity, Department of Brain Sciences, in collaboration with a research team led by Professor Alice Ting at Stanford University, has developed LATeNT, a novel optical control platform that uses light to block signal transmission between neurons and subsequently restore normal signaling.

Polydatin reduces ulcerative colitis by regulating intestinal immune cells

Ulcerative colitis (UC) is a chronic inflammatory bowel disease in which recurrent intestinal inflammation can be difficult to control over the long term.

A Mediterranean ingredient gave gluten-free pasta an unexpected upgrade

Researchers developed carob-enriched gluten-free tagliatelle that increased dietary fiber and antioxidant activity while reducing starch digestibility and improving pasta structure. A 20% carob substitution provided the best overall balance of functional properties, texture, and consumer acceptance, although clinical health benefits remain to be established.

Youth-associated protein reverses age-related microglial changes in mice

Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.

Coral-inspired scaffold enhances bone repair by reprogramming immune cells

SONFH is one of the leading causes of non-traumatic osteonecrosis. Reported in up to 9%–40% of patients receiving prolonged or high-dose glucocorticoid therapy, the condition progressively weakens the femoral head and can eventually lead to joint collapse, making effective bone repair a major clinical challenge.

Mitochondrial rewiring may explain why orthoflaviviruses harm humans but persist in mosquitoes

Orthoflaviviruses reshape mitochondrial structure, metabolism, redox signaling, and quality control differently across human and mosquito models, helping explain their contrasting infection outcomes. The review highlights mitochondrial pathways that may support acute cellular damage in vertebrates but persistent, non-lethal infection in mosquitoes, pointing to potential antiviral targets.

Mitochondrial gene RTN4IP1 drives triple-negative breast cancer metastasis

Triple-negative breast cancer accounts for approximately 15% of all breast cancer cases. It is characterized by the absence of estrogen receptor, progesterone receptor, and HER2 expression, rendering it insensitive to conventional endocrine and targeted therapies.

Cannabis compounds may weaken glioblastoma response to chemotherapy and radiation

Several cannabinoids reduced chemotherapy- and radiation-induced apoptosis in glioblastoma cell models, with effects linked to reduced apoptotic priming, increased pro-survival signaling, and G1 cell-cycle arrest. The findings raise concern that cannabinoid exposure could interfere with some cancer treatments, although the results are limited to laboratory models and require in vivo and clinical validation.
