Hopkins radiologists have found that a combination of positron emission tomography (PET) and computed tomography (CT) detects cancer spread better than PET alone. In a study to be presented at the Radiological Society of North America (Abstract #1458, 10:57 AM, Thursday, December 5, Room S502AB), researchers reported that overall, PET-CT improves the ability to distinguish cancerous from normal tissue and locate metastases, where they have spread. The study used a scanner that fuses CT technology, wh

New software that responds to written questions by retrieving digital images has potentially broad application, ranging from helping radiologists compare mammograms to streamlining museum curators’ archiving of artwork, say the Penn State researchers who developed the technology.

Dr. James Z. Wang, assistant professor in Penn State’s School of Information Sciences and Technology and principal investigator, says the Automatic Linguistic Indexing of Pictures (ALIP) system first build

Penn State acousticians have achieved proof of concept for a compact ice cream freezer case based on “green” technology that substitutes sound waves for environment-damaging chemical refrigerants.

Dr. Steven Garrett, the United Technologies Corporation professor of acoustics at Penn State, leads the research team conducting the project with financial support from Ben & Jerry’s and its parent company, Unilever.

“In our proof-of-concept test system, there is no ’test freeze

Research community questioning legitimacy of Canadian drug approved for market in Africa

With one million deaths and 300 million new cases of malaria each year, the quest for a successful malaria treatment is urgent. But one new drug, touted by its manufacturer as safe and exceptionally effective, and already approved for sale by five African nations, is provoking suspicion in the malaria research community. At best, some researchers claim, the Canadian drug Malarex has not been ade

Researchers at Ohio State University have identified three genes that are involved in the seasonal clock that determines when hamsters reproduce.

While researchers have learned a lot about reproductive clocks in some animals, this study is unique in helping uncover at least part of the genetic basis for determining how the reproductive system shuts off in the fall and restarts in time for spring.

“This study offers some of the first insights into how changes in gene expression are a

Pseudomonas putida has potential for use in bioremediation, promoting plant growth and fighting plant diseases

In a successful transatlantic collaboration, scientists at The Institute for Genomic Research (TIGR) in Rockville, MD, and at four research centers in Germany have deciphered and analyzed the complete genome of a bacterium, i>Pseudomonas putida , that has the potential to be used to remediate organic pollutants in soil as well as to help promote plant growth and fig
