From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

The diet-Alzheimer’s connection is more complicated than “eat this, avoid that”

A mini-review finds that dietary patterns may influence Alzheimer’s disease through interconnected pathways involving neuroinflammation, insulin resistance, oxidative stress, blood-brain barrier dysfunction, homocysteine, and the gut-brain axis. The authors argue that genetics, sex, age, physical activity, and socioeconomic context may modify these relationships, supporting more individualized approaches to nutrition research and dementia prevention.

Review uncovers how tryptophan metabolism affects female reproductive health

In recent years, issues concerning female reproductive health have become a global challenge that cannot be ignored.

Disrupted brain-immune signaling may help drive neurodegeneration

A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans.

Review outlines how SIRT3 protein regulates global metabolic disorders

A comprehensive review published in Engineering systematically outlines the regulatory capacity of silent information regulator 3 (SIRT3), a mitochondrial deacetylase termed the "head goose molecule", and its negentropic mechanism for intervening global metabolic disorders including type 2 diabetes, obesity, and steatotic liver disease.

High antioxidant diet linked to lower risk of cervical cancer in women

In research published in the International Journal of Gynecology & Obstetrics, a diet high in antioxidants was linked with a lower risk of cervical cancer in women.

Researchers put olive and fish oil IV nutrition under the microscope

A systematic review of six randomized trials compared olive-oil-based and fish-oil-containing parenteral nutrition in hospitalized adults, examining infection, inflammation, oxidative stress, liver function, and clinical outcomes. The included studies involved diverse patient groups and lipid formulations, with substantial variation in outcomes and insufficient evidence for a meta-analysis.

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.

Cocoa looks promising for mood, but the brain benefits come with a catch

A review of clinical and preclinical studies suggests cocoa polyphenols may support mood, neuroplasticity, cerebral blood flow, and gut-brain signaling through pathways involving BDNF/CREB, inflammation, and oxidative stress.

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.

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.

Laboratory chemical exposure and poor diet increase odds of health symptoms in young scientists

Young scientists who frequently handle laboratory chemicals and consume relatively few antioxidant-rich foods may be more likely to report symptoms such as fatigue, headaches, pallor, and easy bruising, according to a new study of university students in Nigeria.

The coffee advice given to atrial fibrillation patients may deserve a rethink

The DECAF randomized trial found that adults with persistent atrial fibrillation or atrial flutter assigned to drink at least one cup of caffeinated coffee daily had a 39% lower hazard of recurrent clinically detected AF or flutter than those assigned to avoid coffee and caffeine. The findings challenge longstanding advice to routinely restrict caffeinated coffee in people with AF, while further research is needed to determine whether coffee itself provides a protective effect.

Newly discovered protein pathway limits spinal cord injury damage

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.

Why pulses could play a bigger role in healthy and sustainable diets

A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Ferroptosis-based therapy shows promise for advanced prostate cancer treatment

A recent review explores the rapidly expanding field of ferroptosis-based therapy for prostate cancer, presenting ferroptosis as a promising strategy to overcome resistance in advanced and castration-resistant prostate cancer (CRPC).

Biofortified millet improves toddler gut health without adverse effects

Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes, according to a new study led by researchers at Cornell University's Joan Klein Jacobs Center for Precision Nutrition and Health.

Specialized selenoproteins play critical role in regulating cellular health

A new review highlights the remarkable importance of selenoproteins, a specialized group of molecules that, despite their small size, play a decisive role in shaping cellular fate and maintaining biological balance.

Intertwined cellular processes reshape understanding of diabetes

A deeper understanding of how key cellular processes interact is reshaping perspectives on diabetes and its wide-ranging complications.

Perilla oil may curb platelet reactivity and inflammatory signaling in smokers

An eight-week randomized trial found that daily perilla oil increased plasma and red-cell ALA, plasma EPA, and platelet closure time in healthy smokers. Perilla oil also reduced TNF-α and TBX21 gene expression, but it did not improve broader coagulation, lipid, endothelial, or postprandial markers.
