Biochemists Develop Diagnostic Tool to ID Strains Faster
Biochemists have developed a new tool that can identify a strain of influenza in hours, instead of the usual days or weeks, potentially speeding up the development of new vaccines. A sample of the ... > 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 -
Psychologists, Human-Factors Engineers Design Computer-Generated Educational Outings
Psychologists Janis Cannon-Bowers and Alicia Sanchez are part of the team that created virtual reality field trips -- not just for fun, but to help children learn. Employing some of the latest ... > more -
Radiologists Use CT Scan To
Medical physicists used computed tomography to compose a picture of the body within an ancient mummy. The scan provided more detail in both bone and tissue than a conventional x-ray. The three ... > more -
Materials Chemists Apply Photonic Crystals to Forensics
Photonic crystals -- materials with precise patterns of gaps that make them reflect only selected wavelengths of light -- could soon replace the traditional ink-based fingerprinting. In a new ... > more -
Psychiatrists Can Now Predict An Individual Patient's Response To A Drug
The first in a new generation of gene microarrays, computer chips that chemically or electrically express DNA, can predict how a person's body will metabolize about 25 percent of drugs on the market, ... > more -
Microbiologists and Astrobiologists Help Kids Discover New Species
Extremophiles are microbes that have adapted to extreme environments, such as Utah's Great Salt Lake. But new microorganisms can be found in everyday places, and scientists are showing school kids ... > more -
Pediatric Neurologists Use MRI to Understand How Strokes Impair Verbal Abilities
Children who have speech-impairing strokes often learn to talk again, while adult stroke victims can lose their verbal abilities for good. By giving reading and verbal tests inside the MRI, ... > more -
Rheologists Apply Shear-Thickening Fluids to Protective Gear
Rheologists have created a new way of bullet-proofing clothes using shear-thickening fluids. Fabric treated with shear-thickening granular suspensions can turn soft material into solid protective ... > more -
Information Technologists Design System To Recognize Palm Vein Patterns
