Key points from article :
Scientists created tiny biological robots called Anthrobots from human tracheal cells.
Anthrobots range in size from a hair's width to a sharpened pencil tip and can move across surfaces.
Anthrobots are made from adult human cells without genetic modification, reducing rejection risk.
They are biodegradable and only last a few weeks, making them safe for therapeutic use.
Different Anthrobot shapes and movement patterns were observed, offering potential for design.
They could be used in various applications like clearing plaque, repairing nerve damage, or drug delivery.
Anthrobots help us understand how cells assemble and could lead to new regenerative treatments.
Research led by Michael Levin from Tufts University along with Harvard University, published in Advanced Science.
