Lightning strikes, MRI machines, and other sources of powerful electrical fields can damage medical devices and cause serious brain injury.

The microbiota can influence host behaviour through the gut–brain axis. In this Opinion, Johnson and Foster explore the evolution of this relationship and propose that adaptations of competing gut microorganisms may affect behaviour as a by‑product, leading to host dependence.

A toxic chemical produced by algae and linked to motor neuron disease has been detected in NSW rivers. Its presence — long suspected but now confirmed — could be linked to a disease hotspot in the Riverina.

A scientific experiment to reanimate dead brains could lead to humans enduring a ‘fate worse than death,’ an ethics lecturer has warned.

Last month Yale University announced it had successfully resurrected the brains of more than 100 slaughtered pigs and found that the cells were still healthy.

The reanimated brains were kept alive for up to 36 hours and scientists said the process, which should also work in primates, offered a new way to study intact organs in the lab.

On a recent BBC World Service program (News Hour Extra, 12.18.15), a group of space scientists were gathered to discuss these and other aspects of the post-human era. “What about the human soul”, the moderator asked, wondering whether or not these post-humans would still be human. None of the participants were particularly troubled by the question, since they all had assumed that the soul was no more than the particular configurations of DNA which resulted in varying degre…es of insight, intelligence, creativity, and sensitivity. Post-humans will be no different, they all agreed. Only their individual genomes will have been altered to produce a very different human reality – in other words a different human soul.

Once the human genome was completely sequenced; once efforts to recombine DNA had become a reality; and once a mind-computer interface had been realized, there was never any doubt that a post-human era was coming.

Researchers at the University of California Berkeley recently unveiled a new experimental device for editing brain activity.

Posthumous journal.

Groundbreaking physicist Stephen Hawking left us one last shimmering piece of brilliance before he died: his final paper, detailing his last theory on the origin of the Universe, co-authored with Thomas Hertog from KU Leuven.

The paper, published today in the Journal of High Energy Physics, puts forward that the Universe is far less complex than current multiverse theories suggest.

A new proof by SFI Professor David Wolpert sends a humbling message to would-be super intelligences: you can’t know everything all the time.

The proof starts by mathematically formalizing the way an “inference device,” say, a scientist armed with a supercomputer, fabulous experimental equipment, etc., can have knowledge about the state of the universe around them. Whether that scientist’s knowledge is acquired by observing their universe, controlling it, predicting what will happen next, or inferring what happened in the past, there’s a mathematical structure that restricts that knowledge. The key is that the inference device, their knowledge, and the physical variable that they (may) know something about, are all subsystems of the same universe. That coupling restricts what the device can know. In particular, Wolpert proves that there is always something that the inference device cannot predict, and something that they cannot remember, and something that they cannot observe.

“In some ways this formalism can be viewed as many different extensions of [Donald MacKay’s] statement that ‘a prediction concerning the narrator’s future cannot account for the effect of the narrator’s learning that prediction,’” Wolpert explains. “Perhaps the simplest extension is that, when we formalize [inference devices] mathematically, we notice that the same impossibility results that hold for predictions of the future—MacKay’s concern—also hold for memories of the past. Time is an arbitrary variable—it plays no role in terms of differing states of the universe.”
