The [merging / merge] of human and machine has taken another step forward as researchers have built a "biocomputer". Bioengineers at the University of Indiana in the USA have [combined / combed] laboratory-grown human brain tissue with microelectrodes. The scientists have [daubed / dubbed] their creation Brainoware. It is in its [embryonic / bionic] stage of development, but it can already perform complex tasks such [as / has] voice recognition. Lead researcher Dr Feng Guo hopes his softer-than-usual software will help to [advance / advancement] AI technologies. It could also mean AI hardware uses far [less / fewer] energy than [sole / solely] using silicon chips. Dr Guo said: "This is just [prove-of-concept / proof-of-concept] to show that we can [get / do] the job. We still have a long way to go."

The researchers said their Brainoware system [utilities / utilizes] "organoids". These are artificially grown bundles of tissue and [stem / stern] cells that resemble an [organist / organ] . Dr Guo said his team's organoids are [similar / like] mini-brains. They have transformed and developed neurons, [skin / akin] to those found in the human brain. The researchers say their next step is to investigate how Brainoware can be adapted to [overtake / undertake] higher-level tasks. The technology could one day be used to create [improved / betterment] models [of / to] the brain, and move neuroscience research forward. It could also lead to [cores / cures] for neurological diseases. One major challenge for the researchers is to find solutions for how to keep the living tissue [alive / livelihood] .
