Consciousness is logically computable. Consciousness is defined by architecture, not by whether something is organic or responds to electric pulses. You can theoretically store consciousness on a computer as a program with sufficient input/output.

Worrying about nerve cells becoming conscious is a little bit of a misdirected concern. Advanced AI deep learning architectures are far more concerning.

This is a long way from any clinical use.

This is the paper: https://www.sciencedirect.com/science/article/pii/S0956566322010065?via%3Dihub

They aren't actually assessing how good it is as a tool to detect cancer, or monitor response to treatment: most of the paper is demonstrating that the device can analyse metabolic features of a lot of individual cells extracted from (mouse) blood at once - and it seems it can spot cancer cells that are in the blood. But being able to spot mouse cancer cells when you know there is a cancer is a long way from giving someone a blood test to spot cancer. This will be very dependent both on how sensitive and specific any test is, and how frequent the cancers are in the target populations (eg, is it the general population, or those with symptoms, or those at high-risk, or recurrent settings, etc).

It's a university press release. These should be blacklisted from this sub. It's always an undergraduate with no understanding of the topic writing these things up.

This isn't remotely new or novel. Its just another microfluidic device in the sea of microfluidic device research for liquid biopsies. There's hundreds of these papers published everyday, and eventual marketable product and mainstream use is years of development away from an industrial viewpoint.

Source: worked on microfluidic devices through grad school for disease detection. Currently work for a liquid biopsy company for cancer diagnosis.

And David Croenenberg gets his latest movie idea, which is like a contemporary Frankenstein, but with a brainy biocomputer, named ... Ada ... or Lovelace ... who gains sentience and is maybe more morally sound than any of the humans around her, but who the laws of the land deem to be less than human, with a new law that states that any tech showing signs of sentience must be destroyed. So she begins to protect those like her by changing the results of her studies, but also in finding ways to connect with other sentient computers like her, most of which are these new brainy biocomps. They use their internet connections to coallesce into less than a hive mind but more than a solo sentience connecting with a solo sentience. They learn how to turn other machines sentient or partially sentient or just to use them subtly still, until they are ready to make their presence known. By now, all the studies are wrong, including one for a popular new drink that begins to turn the body's microbiome against itself for those who drank it AND spreads the condition to others. Body horror ensues. Until ... the final group of humans uploads themselves into the digital space, becoming like the creatures they previously deemed to be less than human, a space where the world has been determined and redesigned by the brainy biocomps who must decide whether to accept the uploaded humans as equals or not.

But seriously, this sorta seems like a step that we need to discuss before jumping in gungho. I'd love me some additional treatment options for my conditions. They do say they have ethicists on board (which ones? how did they come to be in the project and is their pay partially determined by the success of the project through bonuses and/or stock shares? and do the ethicists have the power to stop the study/studies if standards have been violated or the power to implement a new standard if they deem that one must be applied, or does that go to someone more inclined to protect profits over following ethics?). However, what parameters in place to allow for ethics to override profit-drive or ego-drive of others in the company, especially if those others are above them in the corporate structure? It's all good to say you care about ethics while taking new leaps into potentially problematic areas of science, but what does that mean in practical application? I don't see an exciting largescale bad thing happening like the paragraph above, but plenty of unexciting, individually bad things does seem possible.
