Researchers used a virus-based CRISPR system to precisely edit the gatekeeper enzyme HMGR in petunias and lettuce, effectively unlocking a natural metabolic “brake” that restricts scent and nutrient production. By fine-tuning this regulatory control rather than disabling the gene entirely, they enabled plants to channel more energy into producing aromatic compounds and health-promoting antioxidants. The result was more vigorous growth, stronger floral fragrance, and enhanced nutritional value. Importantly, because no foreign DNA was introduced, this transgene-free approach offers a powerful new framework for developing higher-quality, nutrient-enriched crops through precision gene editing.

The European Society of Endocrinology (ESE) and the European Society for Paediatric Endocrinology (ESPE) today launch a landmark Joint Guidance for Healthcare Transition from Paediatric to Adult Endocrine Care, aimed at supporting structured and effective transition of young people with endocrine conditions transferring from paediatric to adult health services.

WashU Medicine researchers developed a model to estimate when Alzheimer's disease symptoms will begin based on the accumulation of amyloid and tau proteins in the brain. These proteins build up predictably over time, like tree rings, providing scientists with a clock for Alzheimer's symptoms.

Scientists at Nagoya University in Japan have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus coating essential for keeping the colon lubricated and feces hydrated. Their excess degradation leaves patients with dry, immobile stool. This discovery, published in Gut Microbes, finally explains why standard treatments often fail for millions of people with chronic constipation. Notably, the study shows that Parkinson's disease patients, who suffer from constipation decades before developing tremors, have higher levels of these mucus-degrading bacteria. While constipation in Parkinson’s disease has traditionally been attributed to nerve degradation, these findings suggest that bacterial activity also plays a crucial role in the development of their symptoms.
