- Obesity research boosted by watching hunger in the brain
11-07-2007 · EurekAlert!
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite. Researchers hope the technique, which uses magnetic resonance imaging, will enable a far greater understanding of why certain people become obese when others do not, and why different people have different appetites.

- HYPER-CEST MRI breaks new ground in molecular imaging
10-19-2006 · EurekAlert!
Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for Magnetic Resonance Imaging that allows detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques. Called HYPER-CEST, this technique could become a valuable tool for medical diagnosis, including the early detection of cancer.

- The aging brain: Failure to communicate
12-05-2007 · EurekAlert!
A team of Howard Hughes Medical Institute researchers has shown that normal aging disrupts communication between different regions of the brain. The new research, which used advanced medical imaging techniques to look at the brain function of 93 healthy individuals from 18 to 93 years old, shows that this decline happens even in the absence of serious pathologies like Alzheimer's disease.

- Remote-control MRI exam performed over the Internet
10-24-2006 · EurekAlert!
Radiologists have developed a remote-control mechanism that allows an experienced off-site operator to control a magnetic resonance imaging machine by logging onto the Internet from a personal computer. The quality of the images from remote-control scanning was found to be superior to images obtained by a less-experienced technologist onsite. The technique is outlined in the November issue of Radiology.

- Paleontologists discover most primitive primate skeleton
01-23-2007 · EurekAlert!
The earliest branches of primate evolution are more ancient by 10 million years than previous studies estimated, according to an article featured in the Proceedings of the National Academy of Sciences. Researchers reconstructed the base of the primate family tree by comparing skeletal and fossil specimens representing more than 85 modern and extinct species. The team also discovered two 56-million-year-old fossils, including the most primitive primate skeleton ever described.
