Jumping to reduce vibrations

A pioneering use of mini-trampolines is allowing engineers to better understand effects of vibrations caused by human movement on floors and small bridges. 

Student engineers design, build, fly 3-D 'printed' airplane

(Phys.org)—When University of Virginia engineering students posted a YouTube video last spring of a plastic turbofan engine they had designed and built using 3-D printing technology, they didn't expect it to lead to anything ...

A worthy endeavor

The space shuttle Endeavour's final flight ended Friday, September 21, when it landed at Los Angeles International Airport en route to its new life as an exhibit at the California Science Center. But without Caltech professors ...

'Touching the Sun': Sunita Williams on spacewalk

(Phys.org)—NASA astronaut Sunita Williams, Expedition 32 flight engineer, appears to touch the bright sun during the mission's third session of extravehicular activity (EVA) on Sept. 5, 2012.

Students demo autonomous robotic systems

(Phys.org) -- Pop into Cornell's Autonomous Systems Lab in Rhodes Hall any given day, and a mechanical arthropod might be negotiating a steep ramp, or a Roomba-like rover could be cleaning up a cluttered room.

Project aims to remove space debris

(Phys.org) -- Low Earth Orbit is overcluttered with rogue objects and collision shrapnel that are a constant threat to spacecraft.

Engineers model the threat of avalanches

(Phys.org) -- Snow avalanches, a real threat in countries from Switzerland to Afghanistan, are fundamentally a physics problem: What are the physical laws that govern how they start, grow and move, and can theoretical modeling ...
