Scientists Are Finally Set to Mass-Produce The Active Compound Found in Magic Mushrooms

Posted by in categories: chemistry, neuroscience

For nearly 60 years scientists have known the chemical responsible for magic mushrooms’ psychedelic reputation is a compound called psilocybin. What we haven’t known is the biochemical pathway behind this famous hallucinogen.

Feel free to now tick that one off your chemistry bucket-list. German researchers have identified four key enzymes involved in making the chemical, potentially setting the stage for mass production of a promising pharmaceutical.

Psilocybin was first identified by the Swiss scientist Albert Hofmann way back in 1959, but has only recently re-entered the spotlight as a safe way to treat conditions related to anxiety, depression, and addiction.

Quantum Weirdness Has Been Tested Beyond The Particle Scale For The First Time

Posted by in categories: particle physics, quantum physics

A small tweak on a definitive experiment in quantum physics has allowed scientists to observe for the first time exactly how molecules behave as waves.

The results are solidly in line with what theory covering complex quantum phenomena predicts, so don’t expect any radical new physics here. But as with most quantum experiments, the implications of seeing such a counter-intuitive theory in action makes our head spin.

Researchers from the Universities of Vienna and Tel Aviv have recently collaborated on turning a two-decade old idea into a reality, replacing tiny particles with large organic molecules in a variation on Clinton Davisson and Lester Germer’s classic 1927 double slit experiment in order to test the limits of a law governing their behaviour.

The Vertical Farm

Posted by in categories: education, food, sustainability

The term “vertical farming” has not been around long. It refers to a method of growing crops, usually without soil or natural light, in beds stacked vertically inside a controlled-environment building. The credit for coining the term seems to belong to Dickson D. Despommier, Ph.D., a professor (now emeritus) of parasitology and environmental science at Columbia University Medical School and the author of “The Vertical Farm: Feeding the World in the 21st Century.”

Hearing that Despommier would be addressing an audience of high-school science teachers at Columbia on a recent morning, I arranged to sit in. During the question period, one of the teachers asked a basic question that had also been puzzling me: What are the plants in a soil-free farm made of? Aren’t plants mostly the soil that they grew in? Despommier explained that plants consist of water, mineral nutrients like potassium and magnesium taken from the soil (or, in the case of a vertical farm, from the nutrients added to the water their roots are sprayed with), and carbon, an element plants get from the CO2 in the air and then convert by photosynthesis into sucrose, which feeds the plant, and cellulose, which provides its structure.

In other words, plants create themselves partly out of thin air. Salad greens are about ninety per cent water. About half of the remaining ten per cent is carbon. If AeroFarms’ vertical farm grows a thousand tons of greens a year, about fifty tons of that will be carbon taken from the air.

Physics Just Made the Axe Cooler

By swapping out the traditional wedge-shape for a lever, a new take on the 8,000 year old axe makes the tool more powerful. An added bonus is that the LeverAxe will never getting stuck in wood as it’s being used.

A video of a revised version of the axe has been making the rounds on the internet. The LeverAxe is a decided improvement on the tool that has served humanity (relatively unchanged) for 8,000 years. It uses physics to make the axe safer, more efficient, and that much cooler.

Specialized Neurons That Respond to Pain of Pulling Single Hair Discovered

Posted by in categories: health, neuroscience

Summary: NIH researchers have identified a specific type of sensory neurons which become activated as a result of pulling a single hair.

Source: NIH.

Researchers from the National Institutes of Health have identified a class of sensory neurons (nerve cells that electrically send and receive messages between the body and brain) that can be activated by stimuli as precise as the pulling of a single hair. Understanding basic mechanisms underlying these different types of responses will be an important step toward the rational design of new approaches to pain therapy. The findings were published in the journal Neuron.

The Adult Brain Can Regenerate Neurons in an Unexpected Area, Says New Study

Posted by in categories: health, neuroscience

Scientists have discovered for the first time that adult mouse brains produce new cells in the amygdala, a finding that could eventually lead to better treatments for conditions like anxiety and depression, as well as a better understanding of the brain overall.

The amygdala handles a lot of our emotional responses, especially those relating to fear, and broken connections inside it can lead to anxiety disorders such as post-traumatic stress disorder (PTSD).

If the brain is capable of regenerating neurons in the amygdala, then that’s potentially one way of fighting back against these mental health issues, according to the team from the University of Queensland in Australia.

Forever Labs preserves young stem cells to prevent your older self from aging

Posted by in categories: biotech/medical, life extension

Forever Labs, a startup in Y Combinator’s latest batch, is preserving adult stem cells with the aim to help you live longer and healthier.

Stem cells have the potential to become any type of cell needed in the body. It’s very helpful to have younger stem cells from your own body on hand should you ever need some type of medical intervention, like a bone marrow transplant as the risk of rejection is greatly reduced when the cells are yours.

Mark Katakowski spent the last 15 years studying stem cells. What he found is that not only do we have less of them the older we get, but they also lose their function as we age. So, he and his co-founders Edward Cibor and Steve Clausnitzer started looking at how to bank them while they were young.
