TALLAHASSEE (WTXL) - Here's another amazing feat in the world of 3D printing, a human heart! Researches at Carnegie Mellon have produced numerous human organs using this technology. It prints the soft tissue out and holds it together using a chemical mixture. Before a potential transplant, the chemicals melt away. Eventually, the goal is to successfully perform a transplant.

It sounds like something straight out of Jurassic park; Scientists at the University of California Irvine created a mosquito that can't spread malaria. Using a technology called gene drive they genetically modified a type of mosquito that is incapable of transmitting the disease to humans. These insects are confined to a lab and aren't considered ready for use in the real world just yet.

Songbirds not only sing, but dance to win their mates over. Scientists in Japan just discovered this because of how quick their moves are, which can only be seen when filmed at high speeds. Both sexes are seen doing this dance, which is interesting since female mating displays have been phased out for most species through evolution.
