Burger King's latest creepy stunt to rile up McDonald's, and why do we say trick-or-treat, and what is

mischief night anyways? Here are some of the cool things from the news today.

So this was a quick link on cocky.org yesterday that I wanted to expand on, can lab-grown brains become conscious?

How do scientists know if they are? And what are the ethical implications therein?

So small clumps of lab-grown brains, often no larger than a sesame seed, are called brain organoids.

They're grown from human stem cells and commonplace in labs that study the brain. Alison Muotri, a neuroscientist at the University of

California, San Diego, published a paper last year reporting the finding that some of his team's

human brain organoids had produced coordinated waves of electric activity,

not unlike the kind seen in premature babies, and one of the properties of a conscious brain.

The waves persisted for several months before the team ended the experiment, but the paper

caused a melee of ethical considerations. Should organoids that can achieve consciousness

be afforded rights that other clumps of cells don't have? Should scientists even be allowed

to create organoids that can advance to a level of consciousness? Mootri's study isn't the only

one raising these types of questions.
