Did you hear about Facebook using 7 hundred thousand of us for an undercover study? An on staff scientist at Facebook changed the news feeds to show gloomy and depressing posts and status updates, all to see if that kind of information spreads the bad mood. Since this information was published a couple months ago and people started finding out about it, the Internet is in an uproar. Facebook is thought to have been unethical when conducting this experiment.

A man that suffered from a diving accident, causing him to become quadriplegic can now move his arm thanks to a computer chip implanted in his brain. The experiment, Neurobridge, works by reconnecting the brain directly to the muscles, allowing for voluntary and functional control of a limb. The chip is believed to be the first of its kind in linking to the brain in this way. Scientists want to advance the technology to the point of helping stroke and paralysis victims.

Researchers at MIT, the University of Sydney, Harvard, and Stanford have experienced a breakthrough and hope to soon print a full organ by bioprinting blood vessels. They used an extremely advanced bio-printer to fabricate tiny fibers, all interconnected, which would represent the complex vascular structure of an organ. The cell infused material hardens, the fibers are removed, and there you have it! A complex network of tiny little spaces, mimicking capillaries. This could lead to one day printing a true organ, as well as organ regeneration.

A gadget name SCiO made over 2 million dollars on Kickstarter. The spectrometer absorbs light, reflects it back from an object and turns it into a spectrum. All you do is point the gadget at an object. SCIO reads the items molecular information, then sends it up in the cloud to analyse it, and boom, it tells you what the item is.
