"In a series of experiments, scientists at Purdue University compared weight gain and eating habits in rats whose diets were supplemented with sweetened food containing either zero-calorie saccharin or sugar. The report, published in Behavioral Neuroscience, presents some counterintuitive findings: Animals fed with artificially sweetened yogurt over a two-week period consumed more calories and gained more weight — mostly in the form of fat — than animals eating yogurt flavored with glucose, a natural, high-calorie sweetener. It's a continuation of work the Purdue group began in 2004, when they reported that animals consuming saccharin-sweetened liquids and snacks tended to eat more than animals fed high-calorie, sweetened foods. The new study, say the scientists, offers stronger evidence that how we eat may depend on automatic, conditioned responses to food that are beyond our control."

"A new contact lens embedded with electronic circuits could be the seed for "bionic eyes" that can see displays overlaid on a person's field of view, researchers say."

CNN just broke the news of this groundbreaking study. Shattering all previous assumptions, science has proven conclusively that men seek attractive mates.
"Men's choices did not reflect their stated preferences, the researchers concluded. Instead, men appeared to base their decisions mostly on the women's physical attractiveness.
The men also appeared to be much less choosy. Men tended to select nearly every woman above a certain minimum attractiveness threshold, Todd said.
...The scientists said women were aware of the importance of their own attractiveness to men, and adjusted their expectations to select the more desirable guys."

There's a new project starting with the objective of cataloguing all known species of life in a single, online database. It's sort of a biological Wikipedia:
"Comprehensive, collaborative, ever-growing, and personalized, the Encyclopedia of Life is an ecosystem of websites that makes all key information about life on Earth accessible to anyone, anywhere in the world. Our goal is to create a constantly evolving encyclopedia that lives on the Internet, with contributions from scientists and amateurs alike. To transform the science of biology, and inspire a new generation of scientists, by aggregating all known data about every living species. And ultimately, to increase our collective understanding of life on Earth, and safeguard the richest possible spectrum of biodiversity."
Am I the only one who immediately thinks of Tron's Master Control Program saying "End of Line"? It would be appropriate if this served as an archive of life after some horrible apocalyptic event - but let's not think about that.

Here's a literal take on the viral web. Biomedical scientists used Google Earth to map the spread of the avian flu virus. The simulation contains additional data points including various strains of virus evolution and the hosts organisms that it is able to infect.

The Genetic Science Learning Center at the University of Utah put together a flash site called Mouse Party, which illustrates the effects of drugs on mice. "Take a look inside the brains of mice on drugs! Every drug of abuse has its own unique molecular mechanism. You'll learn how these various drugs disrupt the synapse to make the user feel "high"."
