Patient's generosity after death leads to possible clues for lung disease

.... Preliminary analysis has revealed some promising paths for further research. "With IPF, many areas of the lung look normal, while others are scarred," said Dr. Kaminski. "Using these donated lungs, we can retrieve tissue from multiple locations within the organ and see how they compare." Collagen- and co...

Scientists map the flight of the bumblebee

...amme, allowing him to build up a pattern of flight paths from different places. He said: "We are trying to find out more about how bees forage, or look for their food. We're particularly interested to see if they find certain environments easier to navigate. "For example, do the bees find it easier to...

Underwater robots work together without human input

...he experiment, the ASAP system will determine what paths the underwater robots should follow to take the most information-rich samples, or measurements, of ocean activity. As the ocean changes, automated computer programs will update the sampling strategy under the supervision of the ASAP team. Most of th...

Their higher economy on steep paths cannot be ascribed to a better exchange between potential and kinetic energy, as in our experiments the body centre of mass travelled monotonically uphill (or downhill). A different oscillation pattern of the loaded head-trunk segment, together with ...

Thanks to Rx3 eye cells prefer the cues guiding the way to the eye field. Following them the cells migrate individ...

As a result, they expect to streamline protein folding calculations from trillions of steps to hundreds. The improvement is significant because conventional protein folding...

Does natural selection drive the evolution of cancer?

...t to influence that evolution. Can we push it down paths that might be more beneficial to us?" One idea might be to develop new drugs that would act as benign cell boosters. Such drugs would specifically target the more benign cells in a tumor to increase their relative fitness over their malignant neigh...

At a smaller scale the desired morphology of wrinkles can be achieved by controlling the ion beam intensity." Because ...
