These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause hallucination-like behavior in animal tests. Scientists say the discovery could lead to future treatments for depression, PTSD, and addiction without the intense psychedelic experience. Wed, 13 May 2026 21:07:03 EDT https://www.sciencedaily.com/releases/2026/05/260512202325.htm https://www.sciencedaily.com/releases/2026/05/260506225217.htm A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the virus, these natural compounds act in several ways at once, potentially making it harder for resistance to develop.

Instead of killing everything, this targeted approach blocks only the harmful microbes that drive periodontitis, allowing beneficial bacteria to thrive and restore balance naturally. Mon, 13 Apr 2026 10:02:46 EDT https://www.sciencedaily.com/releases/2026/04/260413043141.htm https://www.sciencedaily.com/releases/2026/03/260328043558.htm Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, it delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments. Sat, 28 Mar 2026 20:57:04 EDT https://www.sciencedaily.com/releases/2026/03/260328043558.htm https://www.sciencedaily.com/releases/2026/03/260319044656.htm The largest review of medicinal cannabis to date found it doesn’t effectively treat anxiety, depression, or PTSD—despite millions using it for those reasons. Researchers warn it could even make mental health worse, raising risks like psychosis and addiction while delaying proven treatments. Some limited benefits were seen for conditions like insomnia and autism, but the evidence is weak. The findings are fueling calls for stricter oversight as cannabis use continues to rise. Fri, 20 Mar 2026 08:27:27 EDT https://www.sciencedaily.com/releases/2026/03/260319044656.htm https://www.sciencedaily.com/releases/2026/03/260311004711.htm THC doesn’t just blur memories—it can create new ones that never happened. In a controlled experiment, cannabis users were much more likely to recall words that were never shown and struggled with tasks like remembering to do something later. Researchers found that THC disrupted many different memory systems at once. Surprisingly, moderate doses caused memory problems similar to higher doses.

Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, altering how neurons function and strengthening the brain’s drive to seek cocaine.

Because the condition is driven by the gradual loss of dopamine-producing cells—leading to tremors, stiffness, and slowed movement—researchers are implanting lab-grown cells directly into the brain’s movement center to replace what’s been lost. Fri, 20 Feb 2026 04:03:58 EST https://www.sciencedaily.com/releases/2026/02/260219040820.htm https://www.sciencedaily.com/releases/2026/02/260217005806.htm A new University at Buffalo study suggests cannabis-infused beverages could help some people cut back on alcohol. In a survey of cannabis users, those who drank cannabis beverages reported cutting their weekly alcohol intake roughly in half and binge drinking less often. Nearly two-thirds said they reduced or stopped drinking alcohol after starting cannabis drinks.

In animal models, low-dose THC reduced inflammation, improved gut bacteria, boosted serotonin, and lowered harmful cholesterol and bile acids. Surprisingly, it also reduced circulating levels of antiretroviral drugs while maintaining viral suppression, potentially protecting the liver. Scientists say the results point to a promising new approach for managing chronic complications of HIV.

After analyzing more than 20 clinical trials involving over 2,100 adults, researchers found no strong proof that cannabis products outperform placebos in relieving neuropathic pain. Even when small improvements were reported, especially with THC-CBD combinations, they weren’t large enough to make a real difference in daily life. Mon, 19 Jan 2026 00:11:47 EST https://www.sciencedaily.com/releases/2026/01/260118233547.htm https://www.sciencedaily.com/releases/2026/01/260106224639.htm Bariatric surgery far outperformed GLP-1 weight loss drugs in a new real-world comparison of more than 50,000 patients. Two years after treatment, surgery patients lost about 58 pounds on average, while those using semaglutide or tirzepatide lost roughly 12 pounds. Even patients who stayed on GLP-1 drugs for a full year saw much smaller results than surgical patients. High dropout rates and real-world challenges appear to blunt the drugs’ effectiveness.

The improvement was small and short-lived, while side effects were more common. Products with little or no THC, including CBD-only formulations, showed no clear benefit. Researchers say more long-term studies are needed. Tue, 30 Dec 2025 20:44:59 EST https://www.sciencedaily.com/releases/2025/12/251224015651.htm https://www.sciencedaily.com/releases/2025/12/251221043225.htm A new study shows dopamine isn’t the brain’s movement “gas pedal” after all. Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. When scientists manipulated dopamine during movement, nothing changed—but restoring baseline dopamine levels made a big difference. The finding could reshape how Parkinson’s disease is treated.

The team’s statewide audit revealed potency inconsistencies that could mislead consumers and affect safe dosing. Beyond THC, the study also found that cannabinoids like CBG and CBGA are underreported. The findings may help shape future regulations and improve consumer trust in the growing cannabis market.

Once thought to affect mainly the young, the opioid epidemic’s fourth wave now engulfs older adults too. Cocaine and methamphetamine are the leading culprits, and experts warn that multi-drug use makes these overdoses especially lethal. Doctors are urged to educate patients and caregivers on prevention and safer pain management.

Researchers at Scripps Research have discovered that a tiny brain region called the paraventricular nucleus of the thalamus (PVT) becomes hyperactive when animals learn that alcohol eases the agony of withdrawal. This circuit helps explain why people relapse: their brains learn that alcohol brings relief from stress and anxiety.

The rate didn’t drop after legalization, suggesting policy changes haven’t altered risky habits. Experts warn that the lack of public awareness around marijuana’s dangers behind the wheel is putting lives at risk.

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.

Marketing of diet-focused processed foods in the 1980s may have played a major role. Food addiction was linked to poor health, weight issues, and social isolation, highlighting long-term risks. Experts warn that children today could face even higher addiction rates in the future.
