How consciousness may rely on brain cells acting collectively — new psychedelics research on rats

Posted by in category: neuroscience

Psychedelics are known for inducing altered states of consciousness in humans by fundamentally changing our normal pattern of sensory perception, thought and emotion. Research into the therapeutic potential of psychedelics has increased significantly in the last decade.

While this research is important, I have always been more intrigued by the idea that psychedelics can be used as a tool to study the neural basis of human consciousness in laboratory animals. We ultimately share the same basic neural hardware with other mammals, and possibly some basic aspects of consciousness, too. So by examining what happens in the brain when there’s a psychedelically induced change in conscious experience, we can perhaps glean insights into what consciousness is in the first place.

We still don’t know a lot about how the networks of cells in the brain enable conscious experience. The dominating view is that consciousness somehow emerges as a collective phenomenon when the dispersed information processing of individual neurons (brain cells) is integrated as the cells interact.

Connective Tissue Cells Reprogrammed Into Muscle Stem Cells Without Genetic Engineering

Posted by in categories: bioengineering, biotech/medical, genetics

A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases – and for those who would like to eat meat, but don’t want to kill animals.

Elon Musk on Neuralink: Solving Brain Diseases & Reducing the Risk of AI

Posted by in categories: biotech/medical, Elon Musk, existential risks, genetics, robotics/AI, singularity

Elon Musk delves into the groundbreaking potential of Neuralink, a revolutionary venture aimed at interfacing with the human brain to tackle an array of brain-related disorders. Musk envisions a future where Neuralink’s advancements lead to the resolution of conditions like autism, schizophrenia, memory loss, and even spinal cord injuries.

Elon Musk discusses the transformative power of Neuralink, highlighting its role in restoring motor control after spinal cord injuries, revitalizing brain function post-stroke, and combating genetically or trauma-induced brain diseases. Musk’s compelling insights reveal how interfacing with neurons at an intricate level can pave the way for repairing and enhancing brain circuits using cutting-edge technology.

Statins use linked to decline in osteoporotic fractures among elderly

Posted by in category: futurism

Researchers have found in a new study that statin use was associated with significant reduction in the risk of osteoporotic fractures among general older population.

Research author Dr Seo said, “Statin users experienced a decline in risk of major osteoporotic fractures, hip fractures and vertebral fractures.”

The study has been published in Osteoporosis International entitled Age-and dose-dependent effect of statin use on the risk of osteoporotic fracture in older adults.

Collision Course: Electromagnetic Waves Interact in Groundbreaking Experiment

Posted by in categories: innovation, physics

Researchers show it’s possible to make photons that cross paths interact, paving the way for technology breakthroughs.

A research team at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) has demonstrated that it is possible to manipulate photons so that they can collide, interacting in new ways as they cross paths. Detailed in the journal Nature Physics.

As the name implies, Nature Physics is a peer-reviewed, scientific journal covering physics and is published by Nature Research. It was first published in October 2005 and its monthly coverage includes articles, letters, reviews, research highlights, news and views, commentaries, book reviews, and correspondence.

FungalTopia: It’s 11:15 in the morning on one of the hottest days in history and I’m in a white-walled exhibition space, staring at a domed structure suspended from the ceiling

Posted by in categories: biotech/medical, climatology, space

The dome is varnished matte black and shaped somewhere between an oversized eco-chic lampshade and a fifth grader’s diorama of a volcano—all pudgy curves and asymmetric slopes. Underneath sits a small table, almost a stool, made of the same amorphous material. The table is fitted with a brass fixture loosely reminiscent of a guitar but (so the adjacent panel tells me) is actually a replica of the 17th-century microscope designed by Dutch scientist Antonie van Leeuwenhoek—a nod to the father of microscopy.

From a speaker concealed in the dome, a voice intones:

In the midst of a global pandemic, on the eve of an irreversible climate emergency, and in the early, thrilling decades of a biotech revolution, the human race began to question its relationship to the natural world. For many years, scientists believed life to be a competition, one that humanity must win… But as biologists learned more about living systems, it became undeniable that interdependence was key to understanding life on Earth.

Research team simulates super diffusion on a quantum computer

Posted by in categories: computing, particle physics, quantum physics

Trinity’s quantum physicists in collaboration with IBM Dublin have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer.

This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.

Experimental microscopic organs: enter the organoid

Posted by in category: biotech/medical

One of the biggest challenges of researching organs in vivo (or as part of an entire, living organism) is that there is little room for error. Finding treatment for a patient’s kidney, intestine, heart, or any organ must be done carefully; if anything goes wrong, it’s the person’s life on the line. Enter the organoid.

First fully realized and developed in the early 2010s, an organoid is a miniaturized and simplified version of an organ produced in vitro (or outside the entire organism: on their own). The organoid has significant use for researchers as it can be grown, researched, then recreated if any treatments cause tissue harm. Isolating the treatments to an in vitro organ gives researchers flexibility; they can focus entirely on targeted treatments without worrying about harming a living patient.


One of the most significant scientific advances of the last ten years, organoids have revolutionized research across several fields, and continue to grow more advanced and helpful year over year. So, what are these microscopic powerhouses, exactly?
