Gummies Good for the Gums
If probiotics have been getting most of the attention, researchers at the Institute of Science Tokyo suggest postbiotics may also warrant a closer look. In a double-blind randomized clinical trial, adults with gingival inflammation but no periodontitis consumed gummies containing heat-inactivated Lactiplantibacillus pentosus ONRICb0240 twice daily for 6 weeks while maintaining their usual oral hygiene routines. In the analysis excluding participants who used NSAIDs, bleeding on probing—a marker of gingival inflammation—fell from 17.6% to 12.3% in the postbiotic-gummy group, while the placebo group changed from 18.9% to 16.6%. Gingival index scores also improved in the postbiotic group, whereas probing depth, attachment levels, plaque scores, and saliva volume changed little. Exploratory post hoc analyses suggested greater BOP reductions among participants with a BMI of at least 22 kg/m², lower baseline bleeding, and better baseline plaque control. No apparent safety concerns were reported, suggesting the gummies may offer a modest adjunctive approach for reducing gingival inflammation, though the findings require cautious interpretation and further validation.

From Parasite to Pharmacy
If the phrase “worms as drug delivery devices” sounds like science fiction, this study from Washington University School of Medicine suggests it may be edging toward science fact. The team genetically engineered the human hookworm Ancylostoma ceylanicum to produce and secrete a human single-chain antibody fragment capable of neutralizing tetrodotoxin (TTX), a potent neurotoxin with no approved antidote. Using CRISPR-Cas9, they inserted the antibody gene into a prioritized genomic safe-harbor region, creating transgenic worms that showed no obvious disruption of nearby gene expression, completed their life cycle in hamsters, and passed the modification to F1 eggs. In a cell-based assay, serum from hamsters infected with the engineered worms neutralized approximately 16.3% of TTX, while serum from animals carrying unmodified worms showed no neutralization. The work serves as an early proof of concept that engineered parasites could potentially function as living biologic factories, delivering therapeutic proteins from inside the body. For now, it remains firmly experimental—but it may be the first time a hookworm has earned a serious place in the conversation about biologic drug delivery.

This Pill Had a Gut Feeling
Weight restoration may put pounds back on the scale for patients with anorexia nervosa (AN), but this study suggests the gut-brain conversation may still be a work in progress. Researchers at the Laureate Institute for Brain Research enrolled 62 females with weight-restored restrictive AN and 57 healthy comparators in a single-blind crossover trial using an ingestible vibrating capsule to deliver controlled gastric stimulation. Participants with AN were significantly less accurate at detecting normal-intensity gut signals and missed them more often, despite no overall group difference in gastric-evoked potential amplitudes. Computational modeling revealed another layer: participants with AN were more likely to expect that gut sensations would not occur and showed learning patterns that reinforced that expectation over time, even when signals were present. The stimulation also triggered a larger increase in hunger ratings in the AN group, suggesting that hunger signaling may be suppressed but potentially re-engageable. Six months later, 16 of 54 participants with follow-up data had relapsed, and several behavioral, computational, and self-reported gut-related markers were associated with relapse risk and eating disorder symptom severity. The findings point to gastrointestinal interoception as a potential biomarker and treatment target in AN, though further validation is needed before these measures can guide clinical care.

Check, Mate
If your usual coffee break is feeling a little predictable, researchers at Spain’s Institute of Food Science, Technology and Nutrition suggest yerba maté may deserve a closer look. In a randomized, controlled crossover trial, 52 healthy or mildly hypercholesterolemic adults who were not habitual maté drinkers consumed 3 cups daily for 8 weeks, with a control-drink period for comparison. Yerba maté intake was associated with reductions in blood pressure in both groups, with the largest changes seen among participants with elevated cholesterol, whose systolic and diastolic pressures fell by 8.2 and 6.6 mmHg, respectively. LDL cholesterol decreased in healthy participants; in the hypercholesterolemic group, lipid measures also improved, but similar changes during the control period mean those findings require caution. Fasting glucose, insulin resistance, and some measures of antioxidant capacity also improved, with effects varying by group and assay. The clearest signal was inflammatory: yerba maté was associated with reductions in IL-6, tumor necrosis factor alpha, interferon-gamma, high-sensitivity C-reactive protein, and several other inflammatory mediators. Healthy participants also had modest reductions in body fat percentage without changes in body weight. Not every finding was definitive, but for a tea long celebrated in South America, the study suggests there may be more brewing beneath the surface than caffeine alone.

Family Ties, GPS Edition
Parents once waited by the phone for that late-night “I made it home” call. Now, many just check an app. A 2026 C.S. Mott Children’s Hospital National Poll found that 52% of parents track the location of their young adult children aged 18 to 25 years, with tracking more common among parents of 18- to 20-year-olds and daughters. The main reasons parents gave were peace of mind (68%) and emergency preparedness (64%), but 71% of tracking parents said the feature stays on all the time. Parents were most likely to check locations when their child was out late at night (44%) or in an unfamiliar place (39%). While 95% said tracking helped them worry less, 23% said it sometimes had the opposite effect and made them more anxious than reassured. Nearly all tracking parents said their child knew about the tracking, though only 54% reported giving them the option to opt out. And in a distinctly modern family twist, 48% of parents said their young adult tracks their location too—suggesting that, in many families, location sharing now goes both ways.
