SGI Reality Center wows SIGGRAPH attendees

August 15, 2001

LOS ANGELES, August 14 — SGI is wowing SIGGRAPH attendees with its 35 by 10 foot wraparound immersive Reality Center visualization facility here.The display seamlessly combines images from three projectors driven by SGI Onyx 3400 computers, generating 3.5 million pixel images in real time.

Demonstrations include a breathtaking journey through the sixth-century Buddhist kingdom of Silla, from the SGI Reality Center in Seoul, Korea; an urban drive-around simulation of… read more

Shake a leg to power your phone

February 8, 2008

A new knee brace can extract 5 watts from walking motion using a method comparable to the “regenerative braking” used in some electric and hybrid motor cars.

Shaking up system of quake predictions

May 6, 2003

“A seismologist in Wisconsin and a geophysicist in California have developed an alarm system that promises to offer at least a few crucial seconds of warning that a major quake is about to strike. Simulations so far suggest that the technique can signal a quake’s magnitude and where the most dangerous ground motion might threaten people and buildings.”

Shape coding replaces risky viruses in DNA nanoparticle therapy

October 16, 2012

dna_molecules_nanopatterns

Researchers from Johns Hopkins and Northwestern universities have discovered how to control the shape of nanoparticles that move DNA through the body and have shown that the shapes of these carriers may make a big difference in how well they work in treating cancer and other diseases.

This study is also noteworthy because this gene therapy technique does not use a virus to carry DNA into… read more

Shape Memory Alloy May Be Ready for Market

July 23, 2002

Interest is picking up in nitinol shape-memory devices for use in toys (dolls with nitinol facial muscles and mobile action figures), medical devices (stents in blood vessels and arteries to keep them from clogging), and other uses. The benefits: shrink components to reduce weight, cut materials costs and improve design flexibility.

Shape, not just size, impacts effectiveness of emerging nanomedicine therapies

August 5, 2008

Researchers at the University of North Carolina at Chapel Hill have demonstrated that nanoparticles designed with a specific shape, size and surface chemistry could deliver lower dosages of drugs to specific cells and tissues in the body and be more effective in treating tumors.

For instance, the scientists discovered that long, rod-shaped particles (diameter, 150 nanometers; height, 450 nanometers) were internalized by cells approximately four times faster than lower… read more

‘Shape-memory polymer’ material could help reconstruct faces

New material molds itself precisely to the shape of the bone defect without being brittle and also supports the growth of new bone tissue
August 18, 2014

A new material that changes shape upon heating could help heal bone lesions caused by injuries, tumor removal or birth defects, such as cleft palates. (The white bar is 1 cm, or less than half an inch long.) (Credit: Melissa Grunlan, Ph.D.)

Texas A&M University researchers have developed a “self-fitting” material that expands with warm salt water to precisely fill bone defects and also acts as a scaffold for new bone growth, as they reported last week at the 248th National Meeting and Exposition of the American Chemical Society.

Currently, the most common method for filling bone defects in the head, face or jaw (known as the cranio-maxillofacial… read more

Shape-shifting car will brace for impact

May 11, 2006

A car that can anticipate a side-on impact and subtly alter its body shape to absorb the force of the crash is being developed by researchers in Germany.

The car will use hood-mounted cameras and radar to spot a vehicle on course for a side-on collision. Once it realizes an impact is imminent, it will activate a shape-shifting metal in the door. This reinforces the bond between door and… read more

Shape-shifting lens mimics human eye

August 3, 2006

A shape-shifting lens has been developed that alters its focal length when squeezed by an artificial muscle, a ring of polymer gel that expands and contracts in response to environmental changes, eliminating the need for electronics to power or control the devices.

Different polymer gels can be used to create a lens that responds to changes in acidity, temperature, light, electric fields or even certain proteins.

A lens… read more

Shape-shifting magnetic bots take a page out of the Dharma playbook

January 30, 2008

Carnegie Mellon University researchers are developing electromagnetic microscopic bots that cling together and can assume virtually any shape.

Down the line that means rapid prototyping and the promise of “claytronics.”

Shape-shifting mobile devices

The phone screen can bend to provide privacy when needed (credit: University of Bristol)

Prototype mobile devices that can change shape on-demand and lead to high “shape resolution” devices of the future.were presented on Monday at the ACM SIGCHI Conference on Human Factors in Computing Systems in Paris.

In the presentation, Dr. Anne Roudaut and Professor Sriram Subramanian, from the University of Bristol‘s Department of Computer Science used shape resolution to… read more

Shape-shifting nanoparticles flip from sphere to net in response to tumor signal

May 30, 2013

Spherical nanoparticles labeled with red or green dye shift their shapes and accumulatte into netlike structures when they encounter a protease secreted by some kinds of cancerous tumors (credit:

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue.

An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materialsread more

Shape-shifting polymer pulls off amazing memory tricks

March 16, 2010

Tao Xie at General Motors has twisted and stretched a Nafion strip into three distinct shapes, and found that it will revert to each shape at the appropriate temperature.

Nafion is polymer material used in some fuel cells. Previously the best shape-memory polymers were able to remember only two shapes.

Shape-Shifting Robot Nanotech Swarms on Mars

March 30, 2005

NASA Astronaut Journal, Mars, 2034:

The latest spacecraft sent to us is more a living thing than a robot. Shortly after launch from Earth, the tiny capsule blossomed into a sail and rode the solar wind to Mars. On the way, a meteoroid punched a hole in the sail, but surrounding material flowed in and closed the tear.

Upon arrival, the spacecraft shrunk more than 100 times its… read more

Shape-shifting robot shows off its moves

November 18, 2004

A shape-shifting robot comprised of many independently moving components, has been demonstrated walking, rolling and slithering for the first time.

The coordinated movement of numerous cells enables the robot to change its overall shape and also move itself along. The cells each have a computer and communicate with each other via an infrared link.
