A New Species Of Psychedelic Lichen Found To Contain Psilocybin & DMT

Posted by in category: biological

A newly discovered species of lichen from Ecuador that contains both tryptamine and psilocybin has recently been discovered, dispelling the belief that the infamous ‘magic mushrooms’ are the only plant species containing this hallucinogenic compound.

Lichens are of particular interest to biologists because of their symbiotic relationship between algae and fungi. The fungus creates the network that sustains, hydrates, and protects the algae, which in turn generates the sugars necessary to feed it through photosynthesis. While they both exhibit plant-like characteristics, neither are actually plants — they are composite organisms. This makes the psychedelic lichen even more intriguing.

The British Military Is Working on Anti-Aircraft Drone Swarms

Posted by in categories: drones, military

A swarm of 150 drones buzzed over Maroon 5 singer Adam Levine’s head during this year’s Super Bowl half time show, spelling out the words “One Love.”

It was a dazzling display of drone technology — and military developers in the United States and United Kingdom are increasingly interested in using something similar, but with a very different goal in mind: to surround enemy aircraft, confusing them and forcing them out of the sky.

A new CRISPR/Cas9 therapy can suppress aging

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

LA JOLLA—(February 18, 2019) Aging is a leading risk factor for a number of debilitating conditions, including heart disease, cancer and Alzheimer’s disease, to name a few. This makes the need for anti-aging therapies all the more urgent. Now, Salk Institute researchers have developed a new gene therapy to help decelerate the aging process.

The findings, published on February 18, 2019 in the journal Nature Medicine, highlight a novel CRISPR/Cas9 genome-editing that can suppress the accelerated aging observed in mice with Hutchinson-Gilford progeria syndrome, a rare genetic disorder that also afflicts humans. This treatment provides important insight into the molecular pathways involved in accelerated aging, as well as how to reduce toxic proteins via .

“Aging is a complex process in which cells start to lose their functionality, so it is critical for us to find effective ways to study the molecular drivers of aging,” says Juan Carlos Izpisua Belmonte, a professor in Salk’s Gene Expression Laboratory and senior author of the paper. “Progeria is an ideal aging model because it allows us to devise an intervention, refine it and test it again quickly.”

Without Bugs, We Might All Be Dead

Posted by in categories: bioengineering, economics, existential risks, food, genetics

There are 1.4 billion insects for each one of us. Though you often need a microscope to see them, insects are “the lever pullers of the world,” says David MacNeal, author of Bugged. They do everything from feeding us to cleaning up waste to generating $57 billion for the U.S. economy alone.

Today, many species are faced with extinction. When National Geographic caught up with MacNeal in Los Angeles, he explained why this would be catastrophic for life on Earth and why a genetically engineered bee could save hives—and our food supply—worldwide.

Fungus provides powerful medicine in fighting honey bee viruses

Posted by in categories: biotech/medical, food, health, security

In field trials, colonies fed mycelium extract from amadou and reishi fungi showed a 79-fold reduction in deformed wing virus and a 45,000-fold reduction in Lake Sinai virus compared to control colonies.

Though it’s in the early stages of development, the researchers see great potential in this research.

“Our greatest hope is that these extracts have such an impact on viruses that they may help varroa mites become an annoyance for bees, rather than causing huge devastation,” said Steve Sheppard, a WSU entomology professor and one of the paper’s authors. “We’re excited to see where this research leads us. Time is running out for bee populations and the safety and security of the world’s food supply hinges on our ability to find means to improve pollinator health.”

A new map of the night sky using the Low Frequency Array @LOFAR telescope charts hundreds of thousands of previously unknown galaxies.

The international team behind the unprecedented space survey said their discovery literally shed new light on some of the Universe’s deepest secrets, including the physics of black holes and how clusters of galaxies evolve.

Excessive Cell Size Contributes to Senescence

Posted by in categories: biotech/medical, life extension

In a new study [1], researchers have identified the reason why cells become defective when they grow too large and why protein creation fails when cells grow larger than their original healthy size, as is typically seen in aged and senescent cells.

They demonstrate that in enlarged yeast and human cells, RNA and protein biosynthesis does not scale in proportion to the additional cell size, which then leads to a dilution of the cytoplasm. This phenomenon is also present in senescent cells, which display similar traits to those of large cells.

The research team concludes that the maintenance of a cell type-specific DNA-to-cytoplasm ratio is essential for the majority of cellular functions, and when cellular growth changes this ratio, it encourages cells to become senescent.
