- UGA research shows rats are capable of reflecting on mental processes
03-08-2007 · EurekAlert!
A new study by researchers from the University of Georgia, just published in the journal Current Biology, shows that laboratory rats possess the ability to think about what they know or don’t know. It's the first demonstration that any non-primate knows when it doesn’t know something, and it could open the way to more in-depth studies about how animals -- and humans -- think.

- What people say may not be what they know
04-30-2007 · EurekAlert!
What a person says is not necessarily an indication of what that person knows because speech is motivated by social circumstances and the desire to influence the listener. Two researchers at the University of Missouri-Columbia have applied this principle to local environmental knowledge by indigenous peoples and are urging other scientists to incorporate more observation and skepticism into their studies.

- Mother knows best: Plant knowledge key to childhood health in remote Amazon
03-22-2007 · EurekAlert!
In a remote area of the Amazon, globalization is threatening the time-honored transmission of plant knowledge from generation to generation, with adverse effects on childhood health and nutrition. In a novel study published online this week in the Proceedings of the National Academy of Sciences, researchers report that parents, and especially mothers, who know more about plants and how to use them, have healthier children, independent of other factors such as education, market participation or acculturation.

- Stuck on you: CEACAM6 helps E. coli stick to intestinal lining in Crohn's disease
05-24-2007 · EurekAlert!
In Crohn's disease, the lining of the small intestine is abnormally colonized by E. coli organisms that are able to adhere to and invade intestinal epithelial cells. A new JCI study shows that these bacteria adhere to a region of intestinal epithelial cells known as the brush border in patients with Crohn's disease, but not in healthy individuals, and that this adhesion depends on expression of the receptor CEACAM6 on the epithelial cell surface.

- Study shows lead-based paint problem isn't isolated to China
09-27-2007 · EurekAlert!
A multinational team of environmental and occupational health researchers has found that consumer paints sold in Nigeria contain dangerously high levels of lead. Increased globalization and outsourcing of manufacturing has drastically increased the likelihood that products with unacceptably high levels of lead are being traded across borders -- including between China and Africa as well into regulated countries like the US.

- NASA provides new perspectives on the earth's changing ice sheets
12-11-2006 · EurekAlert!
It is widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. What most do not know is that until just six years ago, we had no real way of measuring whether the ice sheets were shrinking or growing, or at what rate.

- Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck
04-24-2007 · EurekAlert!
Termites and fungi already know how to digest cellulose, but the human process of producing ethanol from cellulose remains slow and expensive. The central bottleneck is the sluggish rate at which the cellulose enzyme complex breaks down tightly bound cellulose into sugars, which are then fermented into ethanol.
