Treatment with a common diabetes drug effectively shrank these tumors in mice

While most cases of a hormonal disorder called Cushing’s Syndrome are caused by non-cancerous pituitary tumors that secrete too much of a particular hormone resulting in high cortisol levels, the disorder can ultimately lead to an early death for many patients whose tumors cannot be removed surgically.

Now, researchers at Cedars-Sinai Medical Center have found that pituitary tumors express an

Duke University chemists report they have made a significant advance toward producing tiny hollow tubes of carbon atoms, called “nanotubes,” with electronic properties reliable enough to use in molecular-sized circuits.

In a report posted Oct. 28, 2002, in the online version of the Journal of the American Chemical Society, the Duke group described a method to synthesize starting catalytic “nanocluster” particles of identical size that, in turn, can foster the growth of carbon nanotubes that

A genetic variant that can explain the occurrence of a type of rheumatic disorder called SLE has been identified by a research team at Uppsala University, Sweden. The team, led by Associate Professor Marta Alarcón at the Rudbeck Laboratory, is presenting its finding in the latest issue of the scientific journal Nature Genetics.

Nearly 6,000 predominantly young women are victims of systemic lupus erythematosus, SLE. The disease is partly genetic and causes damage to the skin and various organ

A recent study of coral formations in different tropical locations will be used to help geologists reconstruct climate and storm patterns of the past and learn more about the preservation of reefs. The findings will be presented by David Meyer, University of Cincinnati professor of geology, at the upcoming 2002 meeting and exposition of the Geological Society of America.

Meyer’s previous research established that coral reefs can be an index of the ocean’s health and are greatly impacted by

New research at the University of North Carolina sheds light on the process that silences a group of genes in the developing embryo.

Down regulation of gene expression or “gene silencing” is considered crucial in normal development. In the embryo, proteins expressed by different sets of genes help signal the pattern of development, including limb formation. However, when that work is completed, the genes responsible must be turned off, explains Dr. Yi Zhang, assistant professor of bi

Advanced space technology is being found more down-to-earth uses – even within the cars driven on Europe`s roads.

The ESA conference ‘Technology Exchange between Space and Automotive Industry’ is to highlight how spin-offs from space are influencing the evolution of European automobiles, heralding improvements in safety, performance and power. It will take place 6 November at ESOC, Darmstadt in Germany.

“Space technology deals with the challenging conditions of launching an
