From mystical experiences induced by "sacred mushrooms" to the potential use of LSD to treat alcoholism, read it all here. en-us Fri, 13 Mar 2026 06:25:45 EDT Fri, 13 Mar 2026 06:25:45 EDT 60 https://www.sciencedaily.com/images/scidaily-logo-rss.png https://www.sciencedaily.com/news/mind_brain/psychedelic_drugs/ For more science news, visit ScienceDaily. https://www.sciencedaily.com/releases/2026/03/260307213232.htm Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways linked to depression and other brain disorders but appear to cause far fewer psychedelic-like effects.

Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal recall — almost like dreaming while awake. By imaging glowing brain cells in mice, researchers watched this process unfold in real time.

At UCSF, neuroscientist Jennifer Mitchell is testing a pharmaceutical form of LSD called MM120, which has shown striking results in reducing symptoms by promoting neuroplasticity and easing rigid thought patterns. In clinical trials, a single dose significantly outperformed standard treatments, offering hope to those who have found little relief elsewhere.

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.

Surprisingly, common prescriptions like antidepressants were seen as helpful for overall mental health but fell short for eating disorder relief.

Human cells lived over 50% longer, and mice treated with psilocybin not only lived 30% longer but also looked and aged better.

In a groundbreaking trial, a single dose combined with therapy significantly reduced emotional suffering, and these effects often lasted over two years. As follow-up studies expand the research to multiple doses and larger samples, scientists are eyeing a possible new standard of care that merges psychedelics with psychological support.

This rise isn't just in numbers but also in diversity older users today are more likely to be women, college-educated, and higher-income. Researchers suggest legalization and growing social acceptance are contributing factors, especially in states with medical marijuana laws. The trend is especially notable among those with chronic illnesses, raising both opportunities and concerns for medical professionals trying to balance symptom relief with the complexities of aging.

Magicians have long captivated audiences with visual tricks, such as pulling a bunny from a hat or sawing someone in half, but tricks that rely on sound are scarce. A new article explores why creating a magical experience using only sound may be challenging and underscores the importance of making magic accessible to people with blindness.

Tue, 24 Sep 2024 16:57:25 EDT https://www.sciencedaily.com/releases/2024/09/240924165725.htm https://www.sciencedaily.com/releases/2024/09/240918125124.htm Signals in our brain are not always processed in the same way: certain receptors modulate these mechanisms, influencing our mood, perception, and behavior in various ways. One of these is the 5-HT2A receptor, which has a recently discovered unique characteristic: it dampens incoming visual information, giving our brain more space for internal processes and interpretations. This discovery could also help explain the effects of drugs like LSD. When this receptor is overactivated, external sensory input is suppressed, and the brain generates more internally-driven images.

However, that feeling of comfort and safety can't be taken for granted among many people who have turned to psychedelic substances--including psilocybin--to help control their symptoms of depression, anxiety or PTSD. Now, a team of researchers published a study looking into patient perspectives and potential issues when it comes to discussing psychedelics for therapeutic use with their physicians.

Psilocybe arose much earlier than previously thought -- about 65 million years ago -- and the authors found that psilocybin was first synthesized in mushrooms in the genus Psilocybe. Their analysis revealed two distinct gene orders within the gene cluster that produces psilocybin. The two gene patterns correspond to an ancient split in the genus, suggesting two independent acquisitions of psilocybin in its evolutionary history. The study is the first to reveal such a strong evolutionary pattern within the gene sequences underpinning the psychoactive proteins synthesis.

They have then used the information to measure what happens to the neurons when the rats are given psychedelic drugs. The results show an unexpected and simultaneous synchronization among neurons in several regions of the brain.

The principle accurately predicted how real neural networks spontaneously reorganize during learning, as well as how altering neural excitability can disrupt the process.

Now, researchers say a new study in mice shows that psychedelic drugs are linked by their common ability to reopen such critical periods, but differ in the length of time the critical period is open -- from two days to four weeks with a single dose.

Not only does it make people want to eat more, but it also makes them crave the tastiest, most high-calorie foods. Now a new study shows that well-studied nematode worms (C. elegans) react to those chemicals known as cannabinoids in precisely the same way.

However, marmosets have five equidistant digits, and were rarely fooled by the magician. The research adds to evidence that animals struggle to predict movements outside of their own 'biomechanical ability'.
