[Link] First almost fully-formed human [foetus] brain grown in lab, researchers claim

This seems significant:

An almost fully-formed human brain has been grown in a lab for the first time, claim scientists from Ohio State University. The team behind the feat hope the brain could transform our understanding of neurological disease.

Though not conscious the miniature brain, which resembles that of a five-week-old foetus, could potentially be useful for scientists who want to study the progression of developmental diseases.

...

The brain, which is about the size of a pencil eraser, is engineered from adult human skin cells and is the most complete human brain model yet developed

...

Previous attempts at growing whole brains have at best achieved mini-organs that resemble those of nine-week-old foetuses, although these “cerebral organoids” were not complete and only contained certain aspects of the brain. “We have grown the entire brain from the get-go,” said Anand.

...

The ethical concerns were non-existent, said Anand. “We don’t have any sensory stimuli entering the brain. This brain is not thinking in any way.”

...

If the team’s claims prove true, the technique could revolutionise personalised medicine. “If you have an inherited disease, for example, you could give us a sample of skin cells, we could make a brain and then ask what’s going on,” said Anand.

...

For now, the team say they are focusing on using the brain for military research, to understand the effect of post traumatic stress disorder and traumatic brain injuries.

You can't talk about ethical boundaries being pushed unless you place that ethical boundary somewhere first. Otherwise we're back to hand-waving: Can I say that because no one "can yet offer any satisfactory theory of consciousness', chewing on a salad is ethically problematic?

Basically, you can't be both worried and unhappy, and completely unspecific :-/

Is there any particular reason to believe that a salads might be capable of consciousness? No.

Is there any particular reason to believe that brains might be capable of consciousness? Yes - namely the fact that most brains insist on describing themselves as such. Does this imply brains are conscious if and only if they insist on describing themselves as such? No. No more than than a bird is only capable of flight when it's actually literally soaring in the air.
