Acting like a neural switchboard, these cells balance pain with other biological needs. The research could pave the way for personalized treatments that target pain at its brain source—offering hope for millions living with long-term pain. Fri, 10 Oct 2025 06:16:16 EDT https://www.sciencedaily.com/releases/2025/10/251009033126.htm https://www.sciencedaily.com/releases/2025/10/251002073959.htm Penn researchers found that psilocybin can calm brain circuits tied to pain and mood, easing both physical suffering and emotional distress in animal studies. The compound works in the anterior cingulate cortex, bypassing injury sites and offering a dual benefit for pain and depression. Unlike opioids, psilocybin is non-addictive and may provide relief lasting weeks. Thu, 02 Oct 2025 09:10:21 EDT https://www.sciencedaily.com/releases/2025/10/251002073959.htm https://www.sciencedaily.com/releases/2025/09/250926035030.htm Scientists have discovered a way to block pain while still allowing the body’s natural healing to take place. Current painkillers like ibuprofen and aspirin often come with harmful side effects because they shut down both pain and inflammation. But this new research identified a single “pain switch” receptor that can be turned off without interfering with inflammation, which actually helps the body recover. Fri, 26 Sep 2025 19:56:30 EDT https://www.sciencedaily.com/releases/2025/09/250926035030.htm https://www.sciencedaily.com/releases/2025/08/250828002404.htm Using cannabis to self-medicate comes with hidden dangers—new research shows these users face higher paranoia and consume more THC. Childhood trauma further amplifies the risks, especially emotional abuse, which strongly predicts paranoia. Thu, 28 Aug 2025 00:24:04 EDT https://www.sciencedaily.com/releases/2025/08/250828002404.htm https://www.sciencedaily.com/releases/2025/08/250818102944.htm A sweeping review of 67 trials has cast doubt on the use of ketamine and similar NMDA receptor antagonists for chronic pain relief. While ketamine is frequently prescribed off-label for conditions like fibromyalgia and nerve pain, researchers found little convincing evidence of real benefit and flagged serious side effects such as delusions and nausea. The lack of data on whether it reduces depression or opioid use adds to the uncertainty. Mon, 18 Aug 2025 23:32:20 EDT https://www.sciencedaily.com/releases/2025/08/250818102944.htm https://www.sciencedaily.com/releases/2025/08/250803011817.htm Researchers discovered that PTSD may be driven by excess GABA from astrocytes, not neurons. This chemical imbalance disrupts the brain’s ability to forget fear. A new drug, KDS2010, reverses this effect in mice and is already in human trials. It could represent a game-changing therapy. Sun, 03 Aug 2025 03:37:34 EDT https://www.sciencedaily.com/releases/2025/08/250803011817.htm https://www.sciencedaily.com/releases/2025/07/250730030358.htm Stepping into a virtual forest or waterfall scene through VR could be the future of pain management. A new study shows that immersive virtual nature dramatically reduces pain sensitivity almost as effectively as medication. Researchers at the University of Exeter found that the more present participants felt in these 360-degree nature experiences, the stronger the pain-relieving effects. Brain scans confirmed that immersive VR scenes activated pain-modulating pathways, revealing that our brains can be coaxed into suppressing pain by simply feeling like we re in nature. Wed, 30 Jul 2025 03:03:58 EDT https://www.sciencedaily.com/releases/2025/07/250730030358.htm https://www.sciencedaily.com/releases/2025/07/250710113151.htm What if your brain is the reason some pain feels unbearable? Scientists at the Salk Institute have discovered a hidden brain circuit that gives pain its emotional punch—essentially transforming ordinary discomfort into lasting misery. This breakthrough sheds light on why some people suffer more intensely than others from conditions like fibromyalgia, migraines, and PTSD. By identifying the exact group of neurons that link physical pain to emotional suffering, the researchers may have found a new target for treating chronic pain—without relying on addictive medications. Thu, 10 Jul 2025 23:37:05 EDT https://www.sciencedaily.com/releases/2025/07/250710113151.htm https://www.sciencedaily.com/releases/2025/07/250706230311.htm When you're mentally exhausted, your brain might be doing more behind the scenes than you think. In a new study using functional MRI, researchers uncovered two key brain regions that activate when people feel cognitively fatigued—regions that appear to weigh the cost of continuing mental effort versus giving up. Surprisingly, participants needed high financial incentives to push through challenging memory tasks, hinting that motivation can override mental fatigue. These insights may pave the way to treating brain fog in disorders like PTSD and depression using brain imaging and behavior-based therapies.

Unlike traditional painkillers that trigger multiple brain pathways—and often addiction—SBI-810 activates just one specific pathway tied to pain relief, sidestepping the euphoric high, constipation, and tolerance buildup common with opioids. It worked impressively in mice, reducing pain from surgery, fractures, and nerve damage—sometimes outperforming even hospital-grade opioids and gabapentin. Even better, it made opioids more effective at lower doses when used together.

Even subtle forms -- like exclusion from group chats -- can trigger PTSD-level distress. Nearly 90% of teens experienced some form of cyberbullying, accounting for 32% of the variation in trauma symptoms. Indirect harassment was most common, with more than half reporting hurtful comments, rumors or deliberate exclusion. What mattered most was the overall amount of cyberbullying: the more often a student was targeted, the more trauma symptoms they showed.
