| Amid war and disease, World Happiness Report shows bright spot Posted: 19 Mar 2022 05:16 AM PDT In this troubled time of war and pandemic, the World Happiness Report 2022 shows a bright light in dark times. According to the team of international researchers, the pandemic brought not only pain and suffering but also an increase in social support and benevolence. |
| Researchers map human sensory neurons, pursue chronic pain cure Posted: 18 Mar 2022 02:05 PM PDT An investigation into how human sensory neurons differ from animal neurons has provided researchers with important clues in the pursuit of more effective treatments for chronic pain. Researchers are analyzing the origins of how pain is generated by nociceptors in human dorsal root ganglia (DRG) neurons, charting the full transcriptome of messenger RNA strands produced in these cells. |
| Exploring the therapeutic uses of ketamine Posted: 18 Mar 2022 01:14 PM PDT First manufactured more than 50 years ago, ketamine is a fast-acting dissociative anesthetic often used in veterinary and emergency medicine. Ketamine also has a history of being an illicit party drug. Now, ketamine is getting a closer look. |
| Antabuse may help revive vision in people with progressive blinding disorders Posted: 18 Mar 2022 01:14 PM PDT Animal and cell studies show that as retinal cells die in degenerative eye diseases, they make other cells hyperactive, creating noise that further obscures vision. Tests to prove this in humans are hard to conduct, however. Antabuse, an approved drug used to wean people off alcohol, should tamp down this hyperactivity and conclusively show whether hyperactivity plays a role in humans, potentially driving work to find better drugs to help those with progressive vision loss. |
| When the brain sees a familiar face Posted: 18 Mar 2022 01:14 PM PDT Researchers have uncovered new information about how the area of the brain responsible for memory is triggered when the eyes come to rest on a face versus another object or image. |
| Youngest brain tumor patients have significantly poorer outcomes than older pediatric patients Posted: 18 Mar 2022 01:14 PM PDT A researcher has found, through extensive data analysis, that the youngest patients with brain tumors -- those ages birth to 3 months -- have about half the five-year survival rate as children ages 1 to 19. |
| Posted: 18 Mar 2022 10:16 AM PDT As Oregon embarks on a voter-approved initiative to permit psychoactive mushrooms in clinical use, a new systematic evidence review reveals a lack of scientific research describing the interactions between widely used psychiatric medications and psychedelics like psilocybin and MDMA. |
| Marijuana for medical use may result in rapid onset of cannabis use disorder Posted: 18 Mar 2022 08:02 AM PDT A new study shows that using cannabis products to treat pain, anxiety and depression failed to improve these symptoms while doubling the risk of developing the addictive symptoms of cannabis use disorder. People seeking cannabis to treat symptoms of anxiety and depression were at greatest risk of CUD. Contrary to evidence-based medicine, people with medical marijuana cards choose their own products and dosing, suggesting the need for better controls over dispensing, use, and professional follow-up of these patients. |
| Early English lessons have lasting effects Posted: 18 Mar 2022 07:49 AM PDT An earlier study had raised doubts about the effectiveness of learning English in the first grade. Now, researchers have observed that it improves language performance over an extended period of time. |
