          Brain ‘Reset Wave’ May Explain How ECT Rapidly Relieves Depression

          Electroconvulsive therapy (ECT), long misunderstood due to outdated portrayals, remains the most effective treatment for severe, treatment-resistant mental illness. While traditionally thought to work solely through induced seizures, new research reveals that ECT also triggers a second brain event: cortical spreading depolarization (CSD).

          Brain-Targeted mRNA Delivery Breaks the Blood-Brain Barrier

          Researchers have developed lipid nanoparticles (LNPs) that cross the blood-brain barrier (BBB) and precisely target brain cells, a major step toward treating neurological diseases like Alzheimer’s. By attaching short peptides to LNPs, scientists achieved targeted mRNA delivery to neurons and endothelial cells, avoiding invasive procedures. Peptides are smaller, more stable, and easier to use than antibodies, making them ideal for LNP-based therapies.

          Brain’s Quit-or-Wait Dilemma: How We Decide to Persist or Move On

          New research sheds light on how the brain's prefrontal cortex evaluates whether to persist or quit in uncertain situations. Using tasks mimicking real-life dilemmas, researchers found that different brain regions influence patience and adaptability.

          Ketogenic Diet Enhances CAR-T Cancer Therapy

          Researchers have found that a ketogenic diet boosts CAR T cell therapy effectiveness by enhancing tumor control and survival in mice with lymphoma. The key is beta-hydroxybutyrate (BHB), a metabolite produced during ketosis, which CAR T cells prefer as an energy source over glucose. Laboratory models showed that BHB supplementation led to complete cancer remission in most mice and enhanced CAR T cell expansion.

          Disrupted Eating Cycles? Liver-Brain Signals Hold Key to Balance

          A new study highlights how signals from the liver to the brain influence eating patterns tied to our circadian rhythms. This liver-brain communication can become disrupted in people working night shifts or irregular hours, leading to weight gain and metabolic issues.

          How Curiosity Styles Shape Wikipedia Use and Learning

          A study of global Wikipedia browsing patterns reveals three curiosity styles: the focused "hunter," the exploratory "busybody," and the creative "dancer." Data from 482,760 readers in 50 countries shows that cultural factors, such as gender equality and education levels, influence browsing styles, with more egalitarian countries showing greater exploratory browsing.

          Penn AInSights, an AI-based imaging system, enhances radiology by creating precise 3D views of internal organs, enabling early detection of health issues like fatty liver disease and diabetes. By analyzing 2,000 scans per month, it helps clinicians screen for conditions beyond their primary focus. The system's seamless integration into existing workflows and its cost-effectiveness make it a game changer in healthcare, potentially extending lives through early intervention.

          34 Neuron Subtypes Linked to Addiction

          Researchers identified 34 distinct subtypes of medium spiny neurons (MSNs) in the nucleus accumbens, a brain region crucial for reward and addiction. This discovery challenges previous views of MSNs as a homogeneous group, revealing a complex diversity with potential implications for understanding addiction and developing targeted therapies. The study suggests these findings may be conserved across species, offering insights into human brain function.

          Dehydration Impairs Attention in Middle-Aged Adults

          Mild dehydration can impair sustained attention in middle-aged and older adults, though it doesn't affect other cognitive functions. The study involved 78 adults, ages 47 to 70, and assessed their hydration levels and cognitive performance. Results showed that dehydration, common during typical daily activities, reduced attention span over 14 minutes. The findings highlight the need for regular hydration to maintain cognitive function in older adults.
