Technology developed at UC Davis may be gentler, more accurate than mammography
A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center. Developed at UC Davis, the machine is the first breast CT to reach clinical testing in a generation. An early prototype was tested in the 1970s, but abandoned as impractical.
"We think this technology may allow radiologists to routinely detect breast tumors at about the size of a small pea," said John M. Boone, professor of radiology and biomedical engineering at UC Davis and the machines developer. "In contrast, mammography detects tumors that are about the size of a garbanzo bean. Tumor size at detection is one of the most important factors in determining breast cancer prognosis, so if we can detect smaller cancers and do so routinely, survival from this disease will improve."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
