IQWiG publishes a comparative review of inhaled insulin versus insulin administered subcutaneously

There is currently no evidence available that inhaled insulin (Exubera) in diabetes therapy shows advantages over short-acting human insulin or insulin analogues administered subcutaneously. The available studies do not provide evidence that Exubera would improve the quality of life or treatment satisfaction of diabetes patients in Germany. However, they do provide indications of di

In a painstaking set of experiments in overweight mice, scientists from the University of Wisconsin-Madison have discovered a gene that appears to play an important role in the onset of type 2 diabetes.

The finding is important because it provides evidence that the same gene in humans could provide clinicians with a powerful tool to determine the likelihood that some individuals will acquire the condition. Moreover, the finding that the gene works through a pathway not generally

The narrow search for water may miss important clues, say USC geobiologists

The great search for extraterrestrial life has focused on water at the expense of a crucial element, say geobiologists at the University of Southern California.

Writing in the Perspectives section of the May 5 issue of Science, four USC researchers propose searching for organic nitrogen as a direct indicator of the presence of life. Nitrogen is essential to the chemistry of living organisms.

With ESO’s VLT, astronomers find molecular hydrogen at edge of Universe

Using a quasar located 12.3 billion light-years away as a beacon, a team of astronomers detected the presence of molecular hydrogen in the farthest system ever, an otherwise invisible galaxy that we observe when the Universe was less than 1.5 billion years old, that is, about 10% of its present age. The astronomers find that there is about one hydrogen molecule for 250 hydrogen atoms. A similar set of

Biologists have vastly expanded understanding of the biological machinery controlling the intricate process by which plant roots burgeon from single cells into complex tissues. A Duke-led team’s discovery of new components of the root-development pathway in the mustard plant, Arabidopsis thaliana, represents both a scientific and technical achievement, the scientists said.

Scientifically, Arabidopsis is a basic biological model for all flowering plants, so the finding offers insigh

Professor Luis Corrochano Peláez, from the Genetics Department of the University of Seville, and his PhD student Julio Rodríguez Romero, in collaboration with researchers of the Duke University of USA and the University of Salamanca, have identified a gene that allows Phycomyces fungus to react to light and orientate their growth toward it. Results will be published in the prestigious journal “Proceedings of the National Academy of Sciences USA” next week. These researches are part of the scientif
