Improved lubrication from polymers and water, not oil

May 8, 2012 11:34 am | News | Comments

Mineral oil is typically used as a cooling lubricant for machining hard metals and for tool-making machinery on which tools are manufactured, but engineers are now offering an alternative to fossil fuel-based oils that often transport very little heat. The new aqueous biopolymer solutions are actually based on water, which is no worse a lubricant than oil if the right additives are used.

Students automate process of lengthening children’s limbs

April 24, 2012 6:04 am | by Mike Williams | News | Comments

A team of Rice University students has invented a machine designed to improve the process of correcting bone deformities in children. Typically, bone correction devices are manually operated, which children must remember to use and which introduces the possibility of damaging fragile tissues and nerves. The new automated linear lengthener avoids these risks.

Mass-production technique enables robotic insects to spring to life

February 15, 2012 10:28 am | News | Comments

A new technique inspired by elegant pop-up books and origami will soon allow clones of robotic insects to be mass-produced by the sheet. Devised by engineers at Harvard University, the layering and folding process enables the rapid fabrication of not just microrobots, but a broad range of electromechanical devices.

Swiss to craft janitor satellites to grab space junk

February 15, 2012 7:51 am | by John Heilprin, Associated Press | News | Comments

Near-Earth space is full of junk. NASA keeps close tabs on at least 16,000 objects larger than 10 cm in diameter. In an effort to tidy up the mess, the Swiss Federal Institute for Technology (EPFL) is building an $11 million satellite called CleanSpaceOne that will force debris toward Earth, burning it up in the atmosphere.

Alcoa announces restart of iconic forging press in Cleveland
