Inner Mitochondrial Membrane: How Cristae Power the Cell's Energy
The inner mitochondrial membrane folds into cristae—dynamic structures that house up to 90% of cellular energy production machinery and adapt their shape to meet metabolic demands.
- Biology
GLP-1 and Appetite: How Weight-Loss Drugs Rewire the Brain
GLP-1 drugs suppress appetite through brain pathways that control reward and satiety—effects extending beyond blood sugar to food cravings, gastric emptying, and even addictive behaviors.

- Phlebotomine sand flies in Central Europe: new distribution map reveals surprising urban spread
Did you know? Phlebotomine sand flies—vectors of Leishmania parasites and phleboviruses—are establishing themselves across Central Europe, with populations now thriving most often in urban areas rather than wilderness, according to a comprehensive 2025 survey spanning Germany, Austria, Hungary, and Slovakia.
- Hair transplantation linked to major mental health gains when psychological screening is used
Did you know? Hair transplantation can significantly improve self-esteem and emotional well-being—but only when patients are psychologically screened beforehand. Without proper evaluation, some patients experience worsening mental health after surgery.
- TCP gene family in red clover: TpTCP18 regulates branching
Surprising finding: A single gene in red clover, TpTCP18, was expressed up to 34 times more in branch buds than in roots, and when inserted into lab plants, it significantly reduced side-shoot growth—pointing to a molecular switch that crops could exploit to control yield-determining architecture.
- Dance linked to sharper cognition and better mood in older adults
Did you know? A meta-analysis of 13 trials with over 1,100 older adults found that dance interventions improved both cognitive function (g = 0.27) and significantly reduced depression symptoms (g = 0.43) — effects that held across different dance styles and study designs.
- IBD gut microbiome: how multikingdom shifts rewrite disease understanding
Did you know? Inflammatory bowel disease is now recognized as a global epidemic shifting through four distinct epidemiological stages, with alterations in bacteria, fungi, and viruses collectively driving disease pathogenesis in ways researchers are only beginning to decode.
- Clinical reasoning in nursing: 55 factors reshape how we understand decision-making
Quick fact: A 2026 review of 25 studies identified 55 distinct factors that influence clinical reasoning in nurses—revealing that sharp thinking at the bedside depends far less on individual skill alone and far more on organizational support, technology design, and workplace culture than previously recognized.
- Sepsis and gut microbiota: new evidence rewrites role of intestinal dysfunction
Surprising finding: In sepsis, the gut is not just a bystander—it actively drives disease progression through microbiome collapse, barrier breakdown, and metabolic shifts that fuel multi-organ failure.
- Concussion recovery: heart rate variability reveals hidden autonomic dysfunction
Quick fact: People recovering from concussion show altered autonomic nervous system flexibility when watching emotional videos or performing cognitive tasks—changes invisible to standard symptom checklists but detectable through heart rate variability monitoring.
- Gut microbiome linked to feed efficiency in livestock production
Did you know? The trillions of bacteria living in farm animals' digestive systems don't just help break down food—they directly influence how efficiently animals convert feed into body weight, a trait that shapes the economics and environmental footprint of global meat and dairy production.
- Pilates during pregnancy linked to better sleep and reduced back pain
Did you know? A 2025 systematic review of 499 pregnant women found that those who practiced Pilates reported significantly better sleep quality, reduced lower back and pelvic pain, and lower anxiety levels compared to those receiving routine prenatal care alone.
- Blumea genus review: 148 bioactive compounds linked to diverse health effects
Surprising finding: The Blumea genus—used for centuries in Asian traditional medicine—contains 148 documented bioactive compounds, including terpenoids, flavonoids, and alkaloids, now linked to anti-inflammatory, neuroprotective, and metabolic effects in preclinical studies.
- Unintended pregnancy linked to 2-3x lower infant care completion in Sub-Saharan Africa
Quick fact: Infants born from intended pregnancies in Sub-Saharan Africa are three times more likely to receive essential newborn care and twice as likely to be exclusively breastfed compared to those from unintended pregnancies — a gap that may contribute to the region's persistently high infant mortality rates.
- Autism spectrum disorder: gut microbiome emerges as diagnostic biomarker
Surprising finding: researchers are now exploring gut microbiome signatures as potential biomarkers for autism spectrum disorder, moving from basic bacterial cataloging to advanced genetic profiling that could enable earlier diagnosis and personalized treatment—though direct causal evidence in humans remains limited.
- Stroke rehabilitation trials underreport motor learning details
Surprising finding: A review of 166 stroke rehabilitation studies found that while 98% reported what tasks patients practiced, only 37% specified how often they received feedback—a critical element for motor recovery that's often left out of published research.
- Endometriosis and dietary fiber: new review links intake to lower risk
Did you know? Women who eat more dietary fiber—especially from fruits, vegetables, and whole grains—may have a reduced risk of developing endometriosis, a painful condition affecting millions worldwide.
- Motor learning with external focus: new brain imaging reveals why
Surprising finding: Directing your attention to the movement outcome (external focus) rather than your body movements (internal focus) doesn't just improve performance—it fundamentally reorganizes how your brain's motor cortex activates during skill learning.
- Gut microbiota and breast cancer: research surges 8-fold since 2016
Did you know? Research linking gut microbiota to breast cancer has exploded since 2016, with 842 studies published through 2024 exploring everything from cancer mechanisms to new treatments—yet this fast-growing field still lacks a unified understanding of how trillions of gut bacteria influence the world's most common cancer in women.
- Schizophrenia and caffeine: meta-analysis reveals mixed effects on symptoms
Surprising finding: A meta-analysis of 1,406 people with schizophrenia found that caffeine consumption shows no clear overall benefit or harm on symptom severity, but individual studies suggest it may improve negative symptoms (like social withdrawal) while potentially worsening positive symptoms (like hallucinations).
- Marmoset cooperative breeding reveals how social timing drives learning
Surprising finding: Marmosets, one of the few primates besides humans who share infant care across the group, show that the *timing* of social exchanges—not just observation—fundamentally shapes how animals learn from each other.
- Evidence quality assessment tools: scoping review flags limits
Quick fact: A 2026 scoping review of 20 studies found that while automated tools for assessing evidence quality show promise in improving efficiency and consistency, 50% remain experimental prototypes requiring human oversight, and most are designed only for randomized controlled trials—limiting their real-world applicability in public health decision-making.
