Electrical Engineers Develop Pocket-Size Fingerprint Recognition
A new pocket device reads fingerprints and validates them by wireless access to a computer. With this biometrics system, users can avoid using passwords, and get simpler and more secure access to ... > more -
Meteorologists, Wind Engineers Standardize Fujita Scale
The Fujita Scale rates tornadoes based on the damage inflicted upon buildings, so accurate rating requires knowing how resistant buildings were in the first place. Starting February 2007, the ... > 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 -
Astronomers Discover Eight New Gravitational Lenses with Hubble Telescope
Images from the Hubble telescope reveal eight new Einstein rings, joining only three others previously known. Einstein rings are pairs of galaxies, with a foreground galaxy bending the light of a ... > more -
Space Physicists and Atmospheric Scientists Can Now Predict Disruptions Caused by the Sun's Coronal Mass Ejections
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track ... > more -
Auto Designers Test Possibilities Offered by New Materials
New plastics may soon replace metals in auto bodies. Designers are beginning to discover a whole new world of possibilities offered by materials that can be bent into futuristic ... > 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 -
Cardiologists Use Medical Physics to Pinpoint Cause of Chest Pains
Unless a patient with chest pain is checked out right away, it can be difficult to diagnose a heart condition, as opposed to less life-threatening causes such as heartburn. A new stress test can spot ... > more -
Pathologists Use Digital Imaging to Speed Up Cancer Diagnosis
A new digital microscopy system allows doctors to examine biopsy tissue and diagnose breast cancer within hours instead of weeks. The same instrument can be used for all kinds of cancers, and it ... > more -
Materials Scientists Create Polymer Coating Against Fogged Glass
When moisture condenses on a cool surface, droplets can form that are the right size to scatter light, fogging up glass. A new polymer coating draws droplets into nanopores and transforms them into a ... > more
