Scientists Create 3D Bioprinter Capable of Printing Living Human Skin (ibtimes.co.uk)
New submitter drunkdrone quotes a report from International Business Times: Spanish scientists say they have developed a prototype 3D printer that is capable of printing "functional" human skin that can be used for transplant patients, as well as an ethical alternative to animal testing. The so-called bioprinter uses special "ink" consisting of human cells and other biological components to reproduce the natural structure of the skin, including the external epidermis and the deeper dermis layer. These "bio inks" are deposited from special injectors onto a print bed to produce skin that is bioactive and capable of producing its own human collagen, the researchers claim. This means that the 3D-printed skin is, in essence, living tissue, making it suitable for treating burn patients and for testing cosmetic, chemical and pharmaceutical products. According to UC3M, the technology could be used to print other human tissues, although first it needs to be approved by regulators in order to ensure the skin it produces is fit for use on human patients. -
Practical Magnetic Levitating Transmission Gear System Loses Its Teeth
Zothecula writes: A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European nations. The creation of the unit entailed the development of a magnetic gear reducer and corresponding frictionless magnetic axles. Aimed primarily for use in spacecraft due to its extended mechanical life, the system is also adaptable for use in automobiles, railways, and aircraft. -
100 P2P Users Upload 75% of Content
An anonymous reader writes "Researchers say that about 100 people (called pirates in the article) are responsible for 75 percent of all downloading on BitTorrent (and the same group does 66 percent of all uploading), and says that the way to shut down the p2p network is simply to disincentive that relatively small number of people. The other large group identified in the study were people (such as from copyright enforcement agencies) who uploaded fake content to frustrate other users. No suggestions were made about how to prevent people from uploading fake content — but it was suggested that the first group could have their ad revenue cut or could be heavily fined." -
Chroot Jails Made Easy
GonzoJohn writes "There are always difficult jobs to do as a GNU/Linux system administrator. Sometimes the difficulty lies in finding out how to do a particular job, not necessarily the job itself. This can be particularly true in the open source world where documentation can often take a back seat to implementation. But once in a while, you can stumble on a real gem that simplifies even the most difficult administration tasks. One such gem is the Jail Chroot Project. Linux Orbit introduces you to creating chroot-ed environments in this article."
