Fly Jet Lag Free
The new Boeing 787
Dreamliner will be the first
of a new generation of
commercial aircraft provided
with a number of new
technologies to increase
comfort and reduce jet-lag.
Human-factors engineers have

Blimps in Space
On a shoestring, and with
off-the-shelf components,
students are designing
prototypes of robotic blimp
that could one day be used
by the Pentagon. Cheaper
than spy satellites, blimps
can hover in place for

Flying and Radiation Risk
At the high altitudes and
latitudes commercial
airlines fly, crews are
subjected to
higher-than-normal radiation
levels from the sun and
cosmic rays. Physicist

Ultrasound Stethoscope
A new ultrasound stethoscope
ignores outside noise,
allowing medics to hear
life-saving sounds inside
the body. Developed by
electrical engineers, the
device exploits the Doppler
effect as it sends an

Human Factors Engineers Help Faa Develop User-friendly Markings
The Federal Aviation Administration's new Enhanced Surface Markings Project, developed with the help of human factors engineers, promises to reduce the number of collisions on airport runways. The ... > more -
Acoustical Engineers Find Simple Way to Reduce Airplane Noise.
A new landing procedure keeps airplanes higher until they are much closer to the airport. The new procedure, called continuous descent approach, promises to save fuel money while cutting noise levels ... > more -
Physicists, Engineers Capture Lightning with Tethered Rockets
To study lightning, scientists use rockets connected to the ground by wires. They fire the rockets into clouds, triggering electrical discharges, and storing their power. They have found that ... > more -
Automotive Engineers Team Up to Improve Energy-Saving Technology
Mechanical and electrical engineers at DaimlerChrysler, General Motors and BMW have jointly developed a hybrid-vehicle technology that shuts the internal combustion engine off when the vehicle stops. ... > more -
Chemists Create Self-assembling Conductive Rubber
Polymer chemists have created a flexible, indestructible material, called metal rubber, that can be heated, frozen, washed or doused with jet fuel, and still retain its electricity-conducting ... > more -
Automotive Engineers Bend New Materials into Futuristic Shapes
New materials for car bodies may soon transform the auto industry. Auto engineers can mold these carbon-fiber-reinforced plastics into virtually any shape. The materials are both strong and light -- ... > more -
Meteorologists Tap Into Public For Help Tracking Storms
By recording the shape of snowflakes seen under a magnifying glass and submitting the information to a NASA Web site, the public can contribute to a global snow-tracking network. Different types of ... > more -
Chemists Steal Engineering Tricks from Sponges
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even ... > more -
Acoustic Waves Could Help Put Out Flames in Zero-Gravity Environments
Aboard NASA's "Weightless Wonder" airplane, physicists are experimenting with combustion and fluid flows in zero-g and developing a fire extinguishing system based on sound waves. The technique could ... > more -
Finding A Whatchamacallit On The Web
VizSeek is one of the first search engines on the Internet to use a photograph, a 2D image, or a 3D model and transform it into a 3D shape. The search can be narrowed with additional information. The ... > more
