OHSU researchers produce first animal model for stress-induced movement disorder

Research helps physicians understand rare form of ataxia that causes patients to appear ’drunk’ at times
Scientists at Oregon Health & Science University are the first to produce an animal model for episodic ataxia. The condition causes patients to suffer bouts of extreme clumsiness where they have balance, speech and motor difficulties. The research helps scientists better understand this rare and intriguing disorder. It may also help provide valuable information for improved, t

Antibody therapy can increase the effectiveness of cancer vaccine, early studys

The benefit of some cancer vaccines may be boosted by treating patients with an antibody that blocks a key protein on immune system T cells, according to a small, preliminary study led by researchers at Dana-Farber Cancer Institute and Brigham and Women’s Hospital.

The study, to be published online on April 1 in the Early Edition of the Proceedings of the National Academy of Sciences (www.pnas.org), tested the effect of a single injection of the antibody MDX-CTLA4 in nine patients who

Photonic crystals to improve microwave circuits

The principal aim of this PhD paper was the application of the new concepts and ideas of Photonic Crystals and Photonic Bandgap (PBG) to microwave and millimetric circuits and, more concretely, to microstrip circuits which is the most common technology in current use in flat microwave circuits.

Thus, for this thesis, the techniques for optimising the functioning of PBG structures in microstrip technology were studied and the various practical applications of these devices were analysed. For

Splashing down on Titan’s oceans

Titan, Saturn’s largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet. How do they form on Titan? Will they help us to discover how life began on Earth?

ESA’s Huygens probe, arriving at Titan in 2005, will help find answers. Here on Earth, ground-based telescopes are playing their part also. They will help scientists to decide how and where precisely Huygens will land. What will it be –

University Designers Tackle Universal Problem

Designers at Staffordshire University have come up with a solutions package with the potential to make life a lot easier for everyone.

The University’s Centre for Rehabilitation Robotics has spent more than a year involved in PACKAGE, a £1.5 million European Commission project concerned with making small changes to consumer packaging in a bid to improve “openability”

Now after rigorous trials carried out throughout Europe, the Centre are hoping that the world’s bigg

Antibiotic Resistance and Gene Transfer

The way antibiotic resistance spreads and possible problems from genes transferring have been identified by researchers from the Rowett Research Institute in Aberdeen, in new evidence about the way genes pass from one bacterium to another. The research is presented today, Monday 7 April 2003, by Dr Karen Scott at the Society for General Microbiology’s Annual Meeting in Edinburgh.

“We all have a huge number of different bacteria in our guts,” says Dr Scott of the Rowett Research Institute, “a
