Debate simmers over when doctors should declare brain death

Posted by in categories: bioengineering, biotech/medical, ethics, law, neuroscience

Benjamin Franklin famously wrote: “In this world nothing can be said to be certain, except death and taxes.” While that may still be true, there’s a controversy simmering today about one of the ways doctors declare people to be dead.


Bioethicists, doctors and lawyers are weighing whether to redefine how someone should be declared dead. A change in criteria for brain death could have wide-ranging implications for patients’ care.

Can AI Be Controlled?

Posted by in category: robotics/AI

Summary: Dr. Roman V. Yampolskiy, an AI Safety expert, warns of the unprecedented risks associated with artificial intelligence in his forthcoming book, AI: Unexplainable, Unpredictable, Uncontrollable. Through an extensive review, Yampolskiy reveals a lack of evidence proving AI can be safely controlled, pointing out the potential for AI to cause existential catastrophes.

He argues that the inherent unpredictability and advanced autonomy of AI systems pose significant challenges to ensuring their safety and alignment with human values. The book emphasizes the urgent need for increased research and development in AI safety measures to mitigate these risks, advocating for a balanced approach that prioritizes human control and understanding.

Colonizing Jupiter

Posted by in categories: futurism, space

Jupiter and its moon are a rarely considered prospect for colonization, but potentially the ripest opportunity for it in the solar system. In this episode of the Outward Bound series we will examine the options for colonizing each of Jupiter’s primary moons and even discuss ways to colonize the giant planet itself.

Device physics recipe to make spiking neurons

Posted by in categories: biological, chemistry, physics, robotics/AI

Divice recipe for making spiking artificial neurons.


Neurons, which are made of biological tissue, exhibit cognitive properties that can be replicated in various material substrates. To create brain-inspired computational artificial systems, we can construct microscopic electronic neurons that mimic natural systems. In this paper, we discuss the essential material and device properties needed for a spiking neuron, which can be characterized using impedance spectroscopy and small perturbation equivalent circuit elements. We find that the minimal neuron system requires a capacitor, a chemical inductor, and a negative resistance. These components can be integrated naturally in the physical response of the device, instead of built from separate circuit elements. We identify the structural conditions for smooth oscillations that depend on certain dynamics of a conducting system with internal state variables. These state variables can be of diverse physical nature, such as properties of fluids, electronic solids, or ionic organic materials, implying that functional neurons can be built in various ways. We highlight the importance of detecting the Hopf bifurcation, a critical point in achieving spiking behavior, through spectral features of the impedance. To this end, we provide a systematic method of analysis in terms of the critical characteristic frequencies that can be obtained from impedance methods. Thus, we propose a methodology to quantify the physical and material properties of devices to produce the dynamic properties of neurons necessary for specific sensory-cognitive tasks. By replicating the essential properties of biological neurons in electronic systems, it may be possible to create brain-inspired computational systems with enhanced capabilities in information processing, pattern recognition, and learning. Additionally, understanding the physical and material properties of neurons can contribute to our knowledge of how biological neurons function and interact in complex neural networks. Overall, this paper presents a novel approach toward building brain-inspired artificial systems and provides insight into the important material and device considerations for achieving spiking behavior in electronic neurons.

Oregon Confirmed a Human Case of the Bubonic Plague. It Was Likely Caused By a Cat

Posted by in categories: biotech/medical, health

A case of the bubonic plague has hit Oregon, and the likely cause was a cat.

Health officials in Deschutes County announced last week that a resident, who has not been identified, had been diagnosed with the plague, in the state’s first human case in eight years. The individual was likely infected by their cat, the department says.

“All close contacts of the resident and their pet have been contacted and provided medication to prevent illness,” said Dr. Richard Fawcett, the Deschutes County Health Services Officer.
