Optogenetics

Researchers from the George Washington University, US, have developed a portable and low-cost macroscopic mapping system for all-optical cardiac electrophysiology. Their work was published recently in the Journal of Biomedical Optics. Previous scientists adopted human-induced pluripotent stem-cell-derived cardiomyocytes (hiPSC-CMs) as a model of the human heart. Such lab-on-a-chip human hearts can be used to study the disruption in …

WARNING: Biodigital convergence – VIDEO

Biodigital convergence is the interactive combination, sometimes to the point of merging, of digital and biological technologies and systems. Policy Horizons is examining three ways in which this convergence is happening. 1 Full physical integration of biological and digital entities Digital technology can be embedded in organisms, and biological components can exist as parts of digital …

World’s first ‘robot lawyer’ to defend a human in court next month

A ‘robot lawyer’ is all set to defend a speeding ticket on its first day in court next month. In February, an Artificial Intelligence (AI) developed by DoNotPay will advise a defendant during an entire court case, likely making it the first-ever case defended by an AI. The AI will run on a smartphone, listening …

Mind Control by Cell Phone – Scientific American

Hospitals and airplanes ban the use of cell phones, because their electromagnetic transmissions can interfere with sensitive electrical devices. Could the brain also fall into that category? Of course, all our thoughts, sensations and actions arise from bioelectricity generated by neurons and transmitted through complex neural circuits inside our skull. Electrical signals between neurons generate electric fields that radiate out …

AI LaMDA has become conscious?

Google has fired engineer Blake Lemoine on Friday after Lemoine expressed concern early in June that Google's LaMDA artificial intelligence had become sentient. LaMDA is short for Language Model for Dialogue Applications and was programmed by Google as a chatbot that mimics speech by ingesting trillions of words from around the internet. LaMDA is described by …

Robot dog with machine gun hints of a dystopian future – VIDEO

While Boston Dynamics show off their robot’s dance moves, others turn similar-looking devices into dystopian killing machines. Much like their flesh-made cousins, robot dogs do not lack attention on the internet. Many have seen the footage of Spot, a high-tech quadruped developed by the US-based company Boston Dynamics, flaunting its dance moves. However, the latest …

Black Goo

La Mancha Negra (The Black Stain) is a mysterious black substance that has oozed from roads in Caracas, Venezuela, first appearing in 1986.[1] Since the appearance of La Mancha Negra, it has caused multiple car accidents and claimed many lives.[2] Determining the cause of the substance has proven difficult and there are still no definitive explanations,[3] despite almost two decades of …

Prince Charles warns the world of ‘Grey Goo’

Source: The Guardian Gray goo (also can be spelled as: grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass on Earth while building more of themselves,[1][2] a scenario that has been called ecophagy (the literal consumption of the ecosystem).[3] The original idea assumed machines were …
