  • Effects persisted for up to three months after starting the trial, according to researchers.
  • DMT was well tolerated with no serious adverse events reported in the trial.
  • Experts caution that psychedelic experiences can be frightening, underscoring need for careful oversight.
  • Around 332 million people worldwide suffer from depression, with many not fully responding to standard antidepressants.
  • The Czech Republic recently legalised medical psilocybin for psychotherapy, signalling regulatory shifts in Europe.
  • Psychedelics are not yet fully authorised for clinical use in Europe; trials and compassionate-use programmes remain common.
  • Researchers look to psychedelics as promising candidates for treating depression with unmet needs.
  • The trial was phase 2a, indicating preliminary evidence and dose-finding goals for future studies.

Scientists label a 26-foot-tall fossil from 400 million years ago an 'unknown life form'

https://www.earth.com/news/enormous-fossil-discovery-labeled-unknown-multicellular-lifeform-prototaxites-p-taiti/
Earth.com
  • Researchers reclassified Prototaxites taiti as a member of an extinct, unknown eukaryotic group.
  • New cross-section analysis revealed three distinct tube types within the fossil, unlike known fungi.
  • FTIR results showed absence of chitin and other fungal markers in Prototaxites taiti.
  • Molecular fingerprints resembled lignin-like compounds rather than plant or fungal chemistry.
  • Machine-learning models classified P. taiti as distinct from fungi, animals, plants, and bacteria with over 90% accuracy.
  • The Rhynie chert fossil NSC.36 provided a cross-sectional view crucial to the findings.
  • Prototaxites lacks features typical of plants, fungi, or animals, challenging prior classifications.
  • The discovery questions long-held ideas about the Devonian organism’s nature and lineage.
  • Prototaxites formed massive vertical structures and likely absorbed nutrients from decaying matter.
  • The study appears in Science Advances and supports a unique, extinct lineage for Prototaxites.

How hibernating hamsters could help astronauts

Popsci.com
  • Latest finding shows muscle stem cells stay alive but pause activity during extended cold-induced inactivity in hamsters.
  • Inactive cells can restart repair once hamsters warm up, enabling recovery of muscle tissue.
  • Researchers suggest hibernation mechanisms could inform strategies to prevent human muscle loss during aging or extended bed rest.
  • Findings could also relate to protecting muscle during long-term spaceflight where microgravity causes muscle loss.
  • The study, reported by Mitsunori Miyazaki, was conducted at Hiroshima University and published in The FASEB Journal.
  • The research contrasts typical muscle damage during winter with a reversible, energy-saving approach in hibernating animals.
  • The study titles and context appear in Popular Science’s biology and science sections, highlighting cross-disciplinary relevance.
  • Experts see potential for translating animal hibernation insights to medical hypothermia and aging-related muscle loss.
  • The article discusses a broader context of winter biology and energy conservation in animals.
  • Future research may explore how to induce reversible muscle suppression in non-hibernating species.
