WHAT'S NEXT VEHICLES that move slowly down the street, pausing regularly to take photographs with remote-controlled cameras, tend to make the police a bit nervous. But one trailer loaded with imaging equipment that made its way through the streets of central Philadelphia wasn't spying - although at first, Secret Service agents had their doubts. Both the vehicle and a plane that flew over the same area were taking authorized pictures of each building and its surroundings, at the behest of the downtown improvement district. Now the terabytes of imaging data are being used to build a three-dimensional model of central...

PHILADELPHIA – Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. A team of chemists, bioengineers and medical researchers based at the University of Pennsylvania and the University of Minnesota has lodged fluorescent materials called porphyrins within the surface of a polymersome, a cell-like vesicle, to image a tumor within a living rodent. Their findings, which represent a proof of principle for the use of emissive polymersomes to target and visualize tumors, appear in the Feb. 7 online early edition of the Proceedings...

LONDON (Reuters) - Microscopic imaging techniques have enabled scientists to delve deep into the brain of a living animal to see how visual circuitry works. By combining two imaging methods, researchers at Harvard Medical School in Massachusetts produced time-lapse images that gave them a close-up look at the inner workings of the brain -- an achievement that could improve understanding of complex illnesses like epilepsy, Alzheimer's and Parkinson's disease. "Put simply, this technique allows us to see the brain seeing," R. Clay Reid, professor of neurobiology and the lead researcher said Wednesday. "It's an entirely new way of looking at...

Passive millimeter wave imaging growing fast by Yvonne Carts-Powell The area of passive millimeter wave imaging is still in development, but both commercial and military applications abound for the technology. A conference on passive millimeter wave imaging technologies will be held at Aerosense in March. "Most of the world leaders and renown people [in this area] will be there," says Chair Roger Smith of the Air Force Wright Laboratory (Eglin AFB, Florida). Desire and past Active radar at longer wavelengths and infrared (and optical) systems at shorter wavelengths are more mature technologies, but passive millimeter wave sensing could add some...

Space Imaging's IKONOS satellite imaged the planet Mars.

LONDON (Reuters) - A new screening technique being developed by scientists in England may help turn the tables on breast cancer by identifying tumors far earlier. Breast cancer is one of the biggest killers of women across the world, accounting for more than 43,000 deaths a year in the United States and 13,000 in Britain alone. As with all cancers, early detection is key to enhanced survival rates. Currently mammograms can only detect tumors when they have grown to between 10 and 12 millimeters across, but New Scientist magazine reported that a technique being developed at University College London can...
