Assumption of function not always correct
05-01-2007 · EurekAlert!A protein called RecQ takes on a totally opposite function in the bacteria Escherichia coli to the one it fulfills in yeast and in humans, indicating that people seeking to understand the role of different forms in human cells and disease need to consider both possibilities, said researchers from Baylor College of Medicine in a report in the current issue of Molecular Cell.

- Dinosaurs -- stones did not help with digestion
12-20-2006 · EurekAlert!
The giant dinosaurs had a problem. Many of them had narrow, pointed teeth, which were more suited to tearing off plants rather than chewing them. But how did they then grind their food? Until recently many researchers have assumed that they were helped by stones which they swallowed. In their muscular stomach these then acted as a kind of "gastric mill." But this assumption does not seem to be correct, as scientists at the universities of Bonn and Tьbingen have now proved.

The finding, published in Nature, raises the possibility that, like humans, birds may get anxious about the future. The birds, western scrub-jays, are shown to have learned from their previous experiences of food scarcity, storing food for future use in places where they anticipate future slim pickings.

- Findings suggest current approach to drug discovery for Lou Gehrig's disease be re-examined
05-07-2007 · EurekAlert!
Most research on Lou Gehrig's disease therapeutics has been based on the assumption that its two forms (sporadic and hereditary) are similar in their underlying cause. Now, researchers at the University of Pennsylvania School of Medicine have found an absolute biochemical distinction between these two disease variants, suggesting that current approaches to drug discovery should be re-examined.

- Molecular motors and brakes work together in cells
01-30-2007 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine have discovered that microtubules -- components responsible for shape, movement, and replication within cells -- use proteins that act as molecular motors and brakes to organize into their correct structure. If microtubules are not formed properly such basic functions as cell division and transport can go wrong, which may have implications in such disease processes as cancer and dementia.
