DMT Substance Guide: Effects, Common Uses, Safety
DMT has one of the oldest histories of human use.Indigenous groups have been using it for upwards of over 4,000 years in the form of a brew with DMT and MAOI containing plants.
LSD Guide: Effects, Common Uses, Safety
The invention of lysergic acid diethylamide, known as LSD, changed what the scientific and psychiatric community thought about the roots of mental illness.
A short bout of exercise enhances brain function: Researchers discover a gene in mice that's activated by brief periods of exercise
Neuroscientists at OHSU in Portland, Oregon, working with mice, have discovered that a short burst of exercise directly boosts the function of a gene that increases connections between neurons in the hippocampus, the region of the brain associated with learning and memory.
The research is published online in the journal
'Mystical' psychedelic compound found in normal brains of rats
The active ingredient responsible for these psychedelic visions is a molecule called dimethyltryptamine (DMT).
Ultra-small nanoprobes could be a leap forward in high-resolution human-machine interfaces
Researchers have conquered the monumental task of manufacturing scalable nanoprobe arrays small enough to record the inner workings of human cardiac cells and primary neurons..
The neuroscience of autism: New clues for how condition begins
The discovery, published in Neuron, illuminates the molecular details of a key process in brain development and adds to the scientific understanding of the biological basis of autism spectrum disorder (ASD), a condition linked to brain development and estimated to affect about one in 59 children born in the United
Coral reefs shifting away from equator: New research reveals a dramatic rebalancing of young corals from tropical to subtropical waters during the last 40 years
"Climate change seems to be redistributing coral reefs, the same way it is shifting many other marine species," said Nichole Price, a senior research scientist at Bigelow Laboratory for Ocean Sciences and lead author of the paper. "The clarity in this trend is stunning, but we don't yet know whether
Insects feel persistent pain after injury, evidence suggests
The study in the peer-reviewed journal Science Advances offers the first genetic evidence of what causes chronic pain in Drosophila (fruit flies) and there is good evidence that similar changes also drive chronic pain in humans. Ongoing research into these mechanisms could lead to the development of treatments that, for
Neural nets to simulate molecular motion cast: Machine learning allows quantum mechanics to be efficiently applied to molecular simulations
"This means we can now model materials and molecular dynamics billions of times faster compared to conventional quantum methods, while retaining the same level of accuracy," said Justin Smith, Los Alamos physicist and Metropolis Fellow in the laboratory's Theoretical Division. Understanding how molecules move is critical to tapping their potential
Physicists use light waves to accelerate supercurrents, enable ultrafast quantum computing
Then he backed up and clarified all that.
Evolution of life in the ocean changed 170 million years ago
Until that point, the success of organisms living within the marine environment had been strongly controlled by non-biological factors, including ocean chemistry and climate.
Researchers grow active mini-brain-networks
"Because they can mimic cerebral development, cerebral organoids can be used as a substitute for the human brain to study complex developmental and neurological disorders," says corresponding author Jun Takahashi, a professor at Kyoto University. However, these studies are challenging, because current cerebral organoids lack desirable supporting structures, such as
Scientists discover the biggest seaweed bloom in the world
They confirmed that the belt of brown macroalgae called Sargassum forms its shape in response to ocean currents, based on numerical simulations.
HIV eliminated from the genomes of living animals
"Our study shows that treatment to suppress HIV replication and gene editing therapy, when given sequentially, can eliminate HIV from cells and organs of infected animals," said Kamel Khalili, PhD, Laura H. Carnell Professor and Chair of the Department of Neuroscience, Director of the Center for Neurovirology, and Director of
