New nanovesicle therapy shows promise for treating alcohol-related liver disease

Alcohol-related liver disease (ALD) is characterized by hepatocellular injury, oxidative stress, inflammation, and extracellular matrix remodeling, yet effective therapies remain limited.

New workflow tracks lipid changes in oil-producing yeast species

A research team led by Profs. XU Guowang and LIU Xinyu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with researchers from Dalian University of Technology, has developed a high-coverage lipidomics workflow and integrated it with transcriptomics to investigate lipid accumulation and compositional changes in Rhodosporidium toruloides under nitrogen limitation.

Blood may reveal signs of gut-related disease that stool samples miss

In a study of 193 participants, researchers found that blood-based short-chain fatty acid profiles distinguished colorectal cancer, celiac disease, obesity, and healthy controls with 95% accuracy, compared with 59% for stool-based measurements. Combining blood and stool profiles increased accuracy to 97%, suggesting that circulating microbial metabolites may offer valuable diagnostic information, although larger studies are needed to validate the findings.

Blueberries reduced blood vessel inflammation in mice, but only with gut microbes present

A preclinical study found that gut microbes help convert blueberry phytochemicals into circulating metabolites, including hippuric acid, that are associated with reduced vascular inflammation. In mice fed a high-fat diet, blueberry supplementation reduced inflammatory markers and monocyte adhesion to blood vessels, but these benefits disappeared following antibiotic-mediated gut microbial depletion.

Ancient protein model shows early steps in energy metabolism

Researchers in Japan engineered ancestral nucleoside diphosphate kinase variants with restricted amino acid repertoires to explore alternative catalytic functions. One variant, Arc1-12KR, retained its protein fold despite lacking catalytic histidine and unexpectedly converted two ADP molecules into ATP and AMP. The findings reveal alternative catalytic potential in simplified proteins and offer clues to possible routes of energy metabolism during early protein evolution.

New portable device enables fast and accurate detection of PFAS in water

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals known for their exceptional resistance to degradation, earning them the nickname "forever chemicals."

Novel peptide from red alga shows potential for blood glucose control

It is a dietary staple found in sushi, rice wraps, and ramen toppings. Commonly known as nori in Japan and gim in Korea, red seaweed is especially popular across Asia.

Men with lower testosterone at 31 reported good health 15 years later

Researchers analyzed testosterone concentrations measured at age 31 in 2,691 Finnish men and assessed self-reported health, medical conditions, and quality of life at age 46. Men across testosterone quartiles generally reported good health and excellent quality of life, while differences in metabolic and gastrointestinal conditions lost statistical significance after adjustment for waist circumference.

Amyloid fibers help sperm deliver RNA to mouse embryos

Researchers identified RNA-associated amyloid fibrils in human seminal fluid and demonstrated that synthetic PAP fibrils could enter mammalian sperm. In mouse IVF experiments, these fibrils helped sperm deliver RNA to embryos, where the detected reporter-protein signal was at least tenfold higher than without fibril exposure.

Rapid testing technology identifies trace drug contamination in public spaces

The study, published in the Journal of Mass Spectrometry, tested the method in a working UK pub and found traces of cocaine and ketamine on surfaces across bathrooms, tables and bar areas.

New model reduces trial and error in mass spectrometry imaging

Andrei Fedorov and his team have found a way to take some of the guesswork out of mass spectrometry imaging (MSI), potentially giving scientists better tools to explore the molecules that influence our health.

Scientists found a link between Mediterranean diet blood markers and longer survival

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.

Menopause isn't the end of the story for the ovaries

Research reveals that postmenopausal ovaries remain active, showing molecular remodeling linked to inflammation and potential implications for women's health.

Your age may not tell the whole story about your health, but your blood could

Researchers analyzed plasma metabolites from 18,476 individuals aged 1 to 96 years and developed two metabolomic aging measures to assess biological aging, chronic disease, and mortality risk. Accelerated metabolomic aging was associated with greater risks of chronic disease and death, while a separate mortality-linked measure provided additional information about health status and disease burden beyond conventional clinical assessments.

New project receives $2.3 million to develop a database and AI model to identify therapeutic peptides

A group of scientists led by Joseph Brown, assistant professor at the Leslie Dan Faculty of Pharmacy, has received $2.3 million USD in funding to develop a database and AI training model to identify peptides with therapeutic potential.

New research links postmenopausal ovarian tissue remodeling to elevated cancer vulnerability

In a new, paradigm-shifting study in ovaries from 28 women, scientists at Northwestern University and the Buck Institute for Research on Aging found in the decades well past menopause, the ovary remains biologically active and continues to remodel with age, showing increased inflammation and changes in tissue structure. The study also found a molecular link between ovarian aging and cancer.

Coffee, citrus and genetics: What scientists found inside human breast milk

In a bioRxiv preprint, researchers analyzed 458 metabolites in breast milk samples from 349 mothers to investigate how maternal diet, genetics, clinical characteristics, and milk-cell gene expression relate to milk composition. Maternal diet explained the greatest share of metabolite variation among the measured maternal factors, while specific genetic variants and gene-expression patterns were associated with individual metabolites, although the study did not establish effects on infant health.

Buck Institute and Georgetown lead effort mapping harmful protein changes before disease begins

A research "super team" co-led by theBuck Institute for Research on Aging and Georgetown University has received an award of up to $51.7 million from the Advanced Research Projects Agency for Health (ARPA-H) to predict how disease-causing proteins misfold before irreversible damage occurs and use those predictions to develop novel diagnostics and treatments.
