For the first time, scientists solved the high-resolution structure of these compounds when they are actively bound to the 5-HT2A serotonin receptor on the surface of brain cells. This discovery is already leading to the exploration of more precise compounds that could eliminate hallucinations but still have strong therapeutic effects. Psilocybin - the psychedelic compound in mushrooms - has already been granted breakthrough status by the FDA to treat depression.

Researchers have identified how cells in our brains work together to join up memories of separate experiences, allowing us to make educated guesses in everyday life. By studying both human and mouse brain activity, they report that this process happens in a region of the brain called the hippocampus.

In a large group of patients with metastatic colorectal cancer, consumption of a few cups of coffee a day was associated with longer survival and a lower risk of the cancer worsening, researchers report in a new study.

The scientists found that the more curved a toe spring is, the less power the foot inside the shoe has to exert when pushing off from the ground while walking. That means foot muscles are doing less work, and this, the researchers hypothesize, may have consequences such as less endurance and make people more susceptible to medical conditions like plantar fasciitis.

'Citizen scientists' developing homemade COVID-19 vaccines may believe they're inoculating themselves against the ongoing pandemic, but the practice of self-experimentation with do-it-yourself medical innovations is fraught with legal, ethical and public health issues, says a new paper.

Scientists have found that the 'segmentation clock' -- a genetic network that governs the body pattern formation of embryos -- progresses more slowly in humans than in mice because the biochemical reactions are slower in human cells. The differences in the speeds of biochemical reactions may underlie differences between species in the tempo of development.

Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customizing treatment of bacterial infections.

Consuming high fructose corn syrup appears to be as bad for your health as consuming sugar in the form of fructose alone, according to a new study. The study reports health risks related to the type of sugar consumed, but also reveals novel risks when sugars are combined, which has important implications for dietary guidelines.

Students who are quizzed over class material at least once a week tend to perform better on midterm and final exams compared to students who did not take quizzes, according to a new meta-analysis. The researchers found in addition to frequency, immediate feedback from instructors also seemed to positively impact student performance.

Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of tumors than was previously possible.

Social distancing is a key component of the expert-recommended strategy to reduce the spread of COVID-19. Avoiding contact with others, however, may have repercussions in a person's gut microbiome. A new article calls for scientists to more closely examine the ways in which COVID-19 -- and our response to it -- interact with microbial health.
