Researchers from Oregon Health and Science University created the stem cells by fusing skin cells with donated human eggs. The resulting human embryo was "genetically identical to the child." The researchers want to use the stem cells for theraputic cloning, which may one day use the cells as a replacement tissue. 

A team of engineers from the UW teamed up with Bellevue's NanoFacture to create the device which extracts DNA in one step. The team wanted a device simple enough for K-12 kids to use. The machine uses a swab of saliva and takes only three minutes.

Mimic Technologies has created the dV-Trainer and da Vinci Surgical System, a robot simulation software and hardware that allows surgeons to practice their skills. 1,140 hospitals are using at least one of the devices, which cost $85,000 and $99,200. 

After a hard week, it's worth hoping that the urge to reach to outer space will again fire human imagination.

Currently living on the International Space Station, astronaut Chris Hadfield shows us what would happen if you felt sad in zero gravity.
