Research led by scientists at the University of Bristol and co-authored by top US nutritional experts reveals that people following a completely unprocessed diet ate more than 50% greater amounts of food than those eating just UPFs (ultra-processed food), yet still consumed on average 330 fewer calories from food daily. https://medicalxpress.com/news/2026-01-food-diet-adherence-nourished-consume.html Tue, 20 Jan 2026 05:53:47 EST news688110782 Researchers from Kyushu University discovered a previously unrecognized synaptic "hotspot" that forms during adolescence, challenging the long-held view that adolescent brain development was dominated by synaptic pruning. This hotspot fails to form in mice carrying a schizophrenia-associated gene, pointing to a potential link between adolescent synaptic formation and psychiatric disorders, including schizophrenia. https://medicalxpress.com/news/2026-01-synaptic-formation-adolescence-conventional-views.html Wed, 14 Jan 2026 14:00:11 EST news687616321 Scientists at the Paul Scherrer Institute PSI have refined an X-ray diffraction technique for detecting biological structures from nanometers to millimeters—reducing the time needed to make the measurement from around one day to about an hour. This opens up a wide range of possibilities for biomedical research—from analyzing bone and tissue structures to supporting the development of new implants. https://medicalxpress.com/news/2026-01-raying-auditory-ossicles-technique-reveals.html Mon, 12 Jan 2026 13:23:35 EST news687446581 The start of a new year has long been considered an important moment for personal change. Psychological research shows that calendar landmarks such as birthdays, Mondays or the new year can act as mental reset points, making people more likely to reflect on their lives and attempt new goals. This phenomenon was described by researchers more than a decade ago as the "fresh start effect." https://medicalxpress.com/news/2026-01-year-resolutions-harder.html Fri, 02 Jan 2026 09:36:24 EST news686568961 Most New Year's resolutions collapse before the holiday decorations reach the loft—and it's not that people are lazy or necessarily lack motivation. The issue is that most goals are written in the tone of a stern headteacher, which is a fast route to giving up. A good resolution needs to feel alive rather than imposed. Here are four research-backed ideas that can help you stay on track. https://medicalxpress.com/news/2025-12-year-resolutions.html Tue, 30 Dec 2025 15:30:01 EST news686323652 Every year, many of us bravely announce our resolutions for the new year. A glass of champagne on New Year's Eve might add to our confidence in our ability to do better in the coming year and save more, spend less, eat better, work out more, or binge-watch less. https://medicalxpress.com/news/2025-12-year-resolution.html Tue, 30 Dec 2025 10:40:04 EST news686313476 As millions prepare to set New Year's resolutions centered on "eating clean" and "getting fit," new research suggests these habits could also benefit your pillow time. https://medicalxpress.com/news/2025-12-added-perk-year-goals.html Mon, 29 Dec 2025 15:50:01 EST news686209728 Harvard Medical School researchers have uncovered crucial insights into how an emerging class of antiviral drugs works. https://medicalxpress.com/news/2025-12-antivirals-herpesviruses-scientists.html Mon, 29 Dec 2025 12:39:53 EST news686234313 The human brain is a fascinating and complex organ that supports numerous sophisticated behaviors and abilities that are observed in no other animal species.

A team of researchers has identified that two enzymes, KDM1A and KDM5C, interact to act as true "epigenetic guardians." Their role is to silence genes that do not belong to neurons and to keep only the appropriate instructions active. https://medicalxpress.com/news/2025-09-interaction-epigenetic-guardians-neuronal-identity.html Wed, 10 Sep 2025 09:03:04 EDT news676713781 As protein-rich diets become increasingly popular, a new study suggests that categorizing dietary proteins as either animal- or plant-based fails to effectively capture the source-specific differences in their composition, digestive efficiency and accessibility to the gut microbiota. https://medicalxpress.com/news/2025-09-dietary-proteins-digested.html Thu, 04 Sep 2025 16:50:04 EDT news676223401 A research team has identified a novel therapeutic target for recurrent meningioma through precision genomic analysis.

They found that, in rare cases, zinc from the needle shield can leach into the drug solution to be injected and possibly contribute to syringe clogging. https://medicalxpress.com/news/2025-07-zinc-needle-shields-linked-rare.html Wed, 30 Jul 2025 13:32:16 EDT news673101128 From fetal stages through adolescence, the brain undergoes rapid, layered development—from basic motor skills to complex emotional regulation. Yet this very dynamism, coupled with children's physical and behavioral traits, makes brain imaging extraordinarily difficult. Common conditions like autism spectrum disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and perinatal brain injury often leave subtle but critical imprints on early neural architecture. https://medicalxpress.com/news/2025-07-silence-smarts-mri-child-brain.html Wed, 30 Jul 2025 12:05:04 EDT news673095901 Traditional histopathology, crucial for disease diagnosis, relies on chemically staining tissue samples to highlight cellular structures for microscopic examination by pathologists. This labor-intensive "histochemical staining" process is time-consuming, costly, requires chemical reagents, and is destructive to the tissue. https://medicalxpress.com/news/2025-07-ai-virtual-tissue-super-resolution.html Tue, 01 Jul 2025 09:12:04 EDT news670579921 A Caltech-led team has developed a safe, effective, and painless breast imaging technique that incorporates machine learning to help differentiate between suspicious and healthy tissue. The method has now been tested on patients and performs as well as or better than other conventional breast imaging techniques. https://medicalxpress.com/news/2025-06-ai-technique-effective-painless-breast.html Mon, 30 Jun 2025 14:38:05 EDT news670513082 Low-grade serous ovarian cancer (LGSC), accounts for just 5% to 10% of all epithelial ovarian cancers, but its distinct biology makes it especially challenging to treat. While the origin of this disease has not been identified, a multitude of patients are initially diagnosed with non-invasive lesions, or so-called Serous Borderline Tumors. https://medicalxpress.com/news/2025-06-molecular-reveals-benign-borderline-ovarian.html Fri, 27 Jun 2025 08:49:05 EDT news670232941
