Scientists in Cambridge, England have found hidden signatures in the brains of people in a vegetative state that point to networks that could support consciousness — even when a patient appears to be unconscious and unresponsive. The study could help doctors identify patients who are aware despite being unable to communicate.

Although unable to move and respond, some patients in a vegetative state are able to carry out tasks such as imagining playing a game of tennis, the scientists note. Using a functional magnetic resonance imaging (fMRI) scanner, researchers have previously been able to record activity in the pre-motor cortex, the part of the brain that deals with movement, in apparently unconscious patients asked to imagine playing tennis.

It’s Not Science Fiction, It’s Biomimicry– With Guest Dr. Michael Nosonovsky

Via Midwest Real

“In the first half of the 20th century, the prevailing idea was that humans could be masters of nature and the universe. We thought that human power was unlimited. We thought- ‘we can change rivers, we can move mountains,’ we can actually conquer nature. Then sometime in the second half of the 20th century, we made the realization that the relationship between nature and humans is actually much more complex than that.”  -Dr. Michael Nosonovsky.

IMG_6042If you love technology, congratulations! You’re living in what is, without a doubt, the most exciting time for it in human history. We’ve got self-driving cars, Oculus Rift, ubiquitous pocket-dwelling supercomputers and giant televisions in nearly every home. It’s almost enough to make you forget about ISIS, Ebola, killer asteroids and climate disaster.

Almost.

So let’s dampen the fear mongering feedback loop a bit further by jumping the technological brainwashing (I use that phrase with great affection) up a few notches.Read the rest

Paralysed man walks again after cell transplant

Screen Shot 2014-10-21 at 11.35.46 AM

via BBC:

A paralysed man has been able to walk again after a pioneering therapy that involved transplanting cells from his nasal cavity into his spinal cord.

Darek Fidyka, who was paralysed from the chest down in a knife attack in 2010, can now walk using a frame.

The treatment, a world first, was carried out by surgeons in Poland in collaboration with scientists in London.

Details of the research are published in the journal Cell Transplantation.

BBC One’s Panorama programme had unique access to the project and spent a year charting the patient’s rehabilitation.

Darek Fidyka, 40, from Poland, was paralysed after being stabbed repeatedly in the back in the 2010 attack.

Anthropology unlocks clues about Roman gladiators’ eating habits

anthropology

via Phys.org:

Roman gladiators ate a mostly vegetarian diet and drank ashes after training as a tonic. These are the findings of anthropological investigations carried out on bones of warriors found during excavations in the ancient city of Ephesos.

Historic sources report that gladiators had their own diet. This comprised beans and grains. Contemporary reports referred to them as “hordearii” (“barley eaters”).

In a study by the Department of Forensic Medicine at the MedUni Vienna in cooperation with the Department of Anthropology at the Institute of Forensic Medicine at the University of Bern, bones were examined from a gladiator cemetery uncovered in 1993 which dates back to the 2nd or 3rd century BC in the then Roman city of Ephesos (now in modern-day Turkey). At the time, Ephesos was the capital of the Roman province of Asia and had over 200,000 inhabitants.

6 Bullshit “Facts” About Psychology That Everyone Believes

Muspar writing in Cracked back in 2009:

Psychology is one of those subjects that everybody likes to think they know something about. We love to go around diagnosing our friends and co-workers, both to make sense of the world and to make ourselves feel like we’re smarter than they are.

But like any science that makes its way into the pop culture, a lot of the “common sense” statements we hear every day are so wrong that they border on raving idiocy. Such as…

#6. “If You Let Your Anger Out, You’ll Feel Better!”

You always hear people talk about how “cathartic” an experience was and how much better they feel, or you’ll hear them say things like, “If you keep your anger bottled up, one day you’ll just snap!”

In fact the “about to go crazy because he can’t express anger” character is a mainstay in television and movies (see that Simpsons episode where Ned Flanders finally loses it, and every movie where a renegade cop fires his gun into the air instead of unloading on the bad guy who just killed his wife).

The Real Cyborgs

This article by Arthur House in The Telegraph reads like a William Gibson cyberpunk novel, but it’s reality, here and now. He says “Forget wearable tech. The pioneers of our “post-human” future are implanting technology in to their bodies and brains. Should we stop them or join them?”:

Ian Burkhart concentrated hard. A thick cable protruded from the crown of his shaven head. A sleeve sprouting wires enveloped his right arm. The 23 – year-old had been paralysed from the neck down since a diving accident four years ago. But, in June this year, in a crowded room in the Wexner Medical Centre at Ohio State University, Burkhart’s hand spasmed into life.

At first it opened slowly and shakily, as though uncertain who its owner was. But when Burkhart engaged his wrist muscles, its upward movement was sudden and decisive. You could hear the joints – unused for years – cracking.

Curious Signal Could Be Dark Matter Pouring From The Sun’s Core

via io9:

This could be historic: Astronomers from Leicester University have detected a strange signal in the X-ray spectrum that appears to be a signature of ‘axions’ — a hypothetical dark matter particle. It could take years to confirm, but this may be the first direct detection and identification of dark matter.

The study has the potential to significantly advance our understanding of dark matter and the way our Universe works. Though it has never observed directly, astronomers are certain dark matter exists because, without it, galaxies would just unravel and fly apart. Moreover, even though it doesn’t emit or absorb light, it exerts gravitational pull on celestial objects we can observe. To put it bluntly, it’s dark matter that holds the Universe together — and it may comprise up to 85% of all the stuff within it.

The idea of axions has been around for a while. It was postulated by the Peccei-Quinn theory in 1977 to resolve a nasty problem in quantum physics.

[Rap News] The Singularity – feat. Ray Kurzweil & Alex Jones

“Today we travel into the pure world of sci-fi to investigate the much vaunted, mysterious potential future event known as ‘The Singularity’. What will a machine consciousness mean for humanity? What are the ethical, political, military and philosophical implications of strong A.I.? And what would an AI sound like when spitting rhymes over a dope beat? All this and more shall be revealed in Rap News 28: The Singularity – featuring a special appearance from famed technocrat, futurist and inventor, Ray Kurzweil, in full TED talk mode; everyone’s favourite warmonger, General Baxter; and we welcome back the dauntless info warrior Alex Jones, who last made an appearance in RN6. Join Robert Foster on this epic Sci-Fi quest into the future/past of humanity.”
