3D Printed Bionic Ear


Scientists over at Princeton University have combined electronics with biology to create a 3D printed bionic ear. The artificial organ is a result of the team’s exploration into using the prototyping technique to print out cells and nano particles. Purchasing a basic 3D printer online, the researchers, lead by michael alpine, an assistant professor of mechanical and aerospace engineering, used the additive technology–which allowed them to render the complex topology of the ear–to layer a matrix of hydrogel and calf cells (which eventually develop into cartilage) to build up the form; along with silver nano particles to form an antenna. The thin sensory appendage is coiled within the tissue-like structure, with two wires leading from the base of the ear, wrapping around a helical cochlea that ultimately connects to electrodes. It is the team’s first attempt at developing a fully functioning organ, and the intended use of the resulting organ could be used much like a hearing aid, to restore or advance human hearing.

Scientists Can Have Fun Too.

No matter what your profession, people always like to try and a little fun at the work place, and scientists are no different.  You’ll always have your pranksters, and the co-workers who like to have a laugh at someone else’s expense, but sometimes people can take things a bit too far… Enter the pneumatic cannon.

A pneumatic cannon is a pipe-based weapon which uses air pressure (pneumatic), propellant, or propane/gas, or combustion of a gaseous fuel, to launch projectiles at high speeds. First invented during the 1980s by Conor Conor Gaul the popularity of the pneumatic cannon is widespread. They are built to fire all sorts of projectiles, not always for practical use. The projectile can be dangerous and result in life-threatening injuries, including cranial fractures, if a person is hit.

Long story short, if you point a pneumatic cannon large enough at a person… you’re going to mess someone up.  The guy in this video is pure proof of that.

A PLANET Made Of Diamonds.

Astronomers think they have recently found a star that was transformed and condensed into a planet made of solid diamond.  The team was able to detect the “diamond planet” with the 64m radio telescope in Parkes, Australia, and found out that it orbits an unusual star known as a pulsar.  The scientists’ measurements indicate that the planet has slightly more mass than Jupiter, but is 20 times as dense.  With the planet likely to be made largely of oxygen and carbon, its high density means it is almost certainly crystalline, meaning that a large part of the planet may be similar to a diamond.  The pulsar and its planet are part of the Milky Way’s plane of stars and lie 4,000 light-years away in the constellation of Serpens (the Snake).  Lets hope Lil Wayne doesn’t get there first.
