Under certain conditions, private and commercial propeller planes and jet aircraft may induce odd-shaped holes or canals into clouds as they fly through them. These holes and canals have long fascinated the public and now new research shows they may affect precipitation in and around airports with frequent cloud cover in the wintertime.

Research Shows 16-month-olds Infer Causes of Failed Actions
Using a very small amount of statistical information, 16-month-old infants can distinguish between the influence of their own actions and the impact of the outside world, new research concludes. The findings, published in this week's journal Science, give researchers insight into how infants integrate prior knowledge with a handful of statistical data to make accurate inferences about the causes of a failed action.

Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold- or warm-blooded.
Where Have All the Flowers Gone?
Where Have All the Flowers Gone?
It's summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.
But for how long?
Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season.They published their results, funded by the National Science Foundation (NSF), in the current issue of the Journal of Ecology.

Study Reveals Important Aspects of Signalling Across Cell Membranes in Plants
Every living plant cell and animal cell is surrounded by a membrane. These cellular membranes contain receptor molecules that serve as the cell's eyes and ears, and help it communicate with other cells and with the outside world.
The receptor molecules accomplish three basic things in the communication process: 1) recognize an outside signal, 2) transport that signal across the cell's membrane and 3) initiate the reading of the signal inside the cell and then initiate the cell's response to that signal. These steps are collectively known as transmembrane signaling.
