Really cool stuff today:
By studying the ability of newborn rabbit pups to learn the significance of new odors, researchers have found that a mammary pheromone secreted in mother's milk may act as a chemical booster that facilitates the ability of pups to quickly associate environmental odors with the opportunity to nurse.
A major stress in a carrot's life -- like the slash of a kitchen knife -- and the tapered tuber kicks in the juice and pumps up its phytochemicals. That's the finding of Dr. Luis Cisneros, Texas Agricultural Experiment Station food scientist. He calls it abiotic stress -- pushing the button, so to speak, on a crop after it has been harvested.
Seals shiver when exposed to cold air but not when diving in chilly water, a finding that researchers believe allows the diving seal to conserve oxygen and minimize brain damage that could result from long dives. This research into hypothermia and hypoxia is important to treating people who are hypothermic or who have suffered hypoxia following cardiac arrest, stroke, etc. Research was presented at the American Physiological Society conference, " Comparative Physiology 2006: Integrating Diversity."
Evidence of host-symbiont cospeciation in an insect gut symbiont suggests that long-term vertical transmission and population structure are central forces driving the genomic changes characteristic of insect nutritional symbionts, according to a study published in PLoS Biology.
Scientists revealed today that a prolific parasite is helping shape the destiny of a species it does not even infect. The complex relationship between the parasite, its host and the unconnected species is the first known example of evolutionary pressure from such a remote source.
As many as 18 percent of adults who have no history of stroke report having had at least one symptom of stroke, according to results of a large national study published in the October 9 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
I just wanted to thank you for these posts. I didn't even know about ScienceDaily until I saw these entries from you, and now it's a regular part of my daily intake because you kept pointing out all the good stuff they were reporting. Again, thanks!
