Medical Xpress / Short-term antibiotic use linked to long-lasting resistance in gut bacteria
Stanford University researchers report that ciprofloxacin use drives persistent antibiotic resistance in human gut bacteria, with resistance emerging independently across diverse species and enduring for over 10 weeks.
Medical Xpress / Legalizing cannabis edibles linked to increased adolescent use in Canada
University of Manitoba and Memorial University of Newfoundland researchers are reporting that legalization of youth-oriented cannabis edibles and extracts in Canada was associated with higher cannabis use among adolescents ...
Phys.org / Live imaging reveals how viruses spread through the gut microbiome
Researchers at the University of California, Irvine have developed a live-imaging system, Phollow, that tracks individual bacteriophages as they spread through the gut of zebrafish, showing that phages from different bacterial ...
Phys.org / Stem cells need positional signals to drive regeneration, flatworm study reveals
Scientists at the National Cancer Institute and partnering institutions have discovered that Schmidtea polychroa, a flatworm capable of regenerating lost tissue, develops this ability progressively during early life stages. ...
Medical Xpress / Clinical trial finds novel nutritional formula effectively treats gut microbial overgrowth
Cedars-Sinai researchers have developed a novel nutritional formula, mBiota Elemental, a palatable elemental diet (PED) that reduces the abundance of key gut microbiome taxa and improves symptoms in patients with small intestinal ...
Phys.org / Gene syntax shown to control variability in synthetic plasmids
Engineers and biologists at Dartmouth College have found that, just like word order affects meaning in a sentence, the placement of genes within a plasmid—known as gene syntax—can influence how strongly each gene is expressed, ...
Medical Xpress / Hearing loss in older adults linked to nearly one-third of dementia cases
A multi‑institution research team including Columbia, Vanderbilt, Johns Hopkins and others, report that nearly one in three new dementia cases in older adults is associated with hearing loss, based on statistical modeling ...
Medical Xpress / BMI remains a reliable indicator of excess body fat in most adults, study finds
Johns Hopkins University researchers have found that nearly all adults identified as having obesity based on body mass index (BMI) also had confirmed excess adiposity.
Medical Xpress / Living alone with depression and anxiety raises suicide risk by more than 500%, study of Korean adults suggests
An international team including Charité Universitätsmedizin Berlin, Soongsil University, and Sungkyunkwan University has found that Korean adults living alone with both depression and anxiety face a 558% increased risk of ...
Medical Xpress / New blood test detects tumor-derived cell-free RNA with high sensitivity
Somewhere in the body of a patient, a small clump of cells, growing undetected, has begun to form a tumor. It has yet to cause pain or visible symptoms of illness. Several months from now, or perhaps years, those first signs ...
Medical Xpress / Mixed results: Study finds potential link between infant acid-suppressants and celiac disease
Tel Aviv University-led research has found that infants prescribed acid-suppressive medications during their first six months of life had an increased risk of developing celiac disease autoimmunity under certain study conditions.
Medical Xpress / Using MRI, researchers chart brain growth and development during early childhood
University of North Carolina-led researchers have used brain connectivity charts built from functional MRI data as a tool for tracking early childhood brain development.
Phys.org / Extreme microbial adaptations arise in one of America's most polluted waterways
The industrially ravaged Gowanus Canal, long regarded as a symbol of urban environmental neglect, is being reimagined through the lens of scientific inquiry as a complex reservoir of microbial life shaped by intense selective ...
Phys.org / The complex origin story of domestic cats: Research points to Tunisia
Researchers looking into the origin of domestic cats have long considered that cats likely accompanied early farmers during the Neolithic, spreading through Europe alongside the adoption of agriculture.
Medical Xpress / Single-dose vaccine demonstrates sustained efficacy against RSV-related lower respiratory tract disease in older adults
Researchers from GlaxoSmithKline have reported that a single dose of the RSV vaccine, Arexvy (RSVPreF3 OA), provides effective protection against respiratory syncytial virus-related lower respiratory tract disease (RSV-LRTD) ...
