Scientists have discovered that tissue from pig bladders can be dried into a powder called extracellular matrix and used to regrow human fingers.The lining of pig’s bladder contain a protein that stimulates a total regrowth of tissue, similar to how lizards can regrow their tails. It actually allows to repair muscle damage and regrow fingertips.

Scientists have been able to insert spider silk genes into goats. The goal here was to make the goats produce milk containing a protein responsible for the silk, to harvest it, and produce a material up to 5 times as hard as steel.

Scientists have injected human embryonic stem cells into the brains of fetal mice. They helped develop the mouse brains along with the mouse stem cells. This proves that human stem cells can develop in an animal's organism, outside of a human's body.

The FDA has approved implantation in humans, meaning soon prisons, hospitals, and companies could use the chips to track people’s locations, medical history, and to grant or deny access to rooms and documents.

Scientists are working hard at developing a 21st century woolly mammoth using well-preserved 10,000-year-old blood.

Scientists at the University of California have implanted electrodes in giant flower beetles that allow them to wirelessly signal the beetles to turn, take off, or hover mid-flight.

Scientists have genetically engineered cows so their milk contains the human protein lactoferrin, most commonly found in human breast milk. The protein fights a wide range of infections and is an excellent immune system booster.

Technology now allows researchers to use pig stem cells to grow pig muscle cells. Furthermore, they've grown edible meat in a lab.

The Energy Autonomous Tactical Robot (EATR) fuels itself by consuming bio mass by using claws and chainsaws to chop down plants that are then burned in an interior furnace and turned into steam energy. It's been criticized for allegedly eating any bio mass, with animals and human copses included, but its developers assure that it's vegetarian.
