Researchers ‘smell’ new receptors that could underlie the many actions of the anesthetic drug ketamine

Researchers are continuing their work in trying to understand the mechanisms through which anesthetics work to elicit the response that puts millions of Americans to sleep for surgeries each day. Their most recent study looked at ketamine, an anesthetic discovered in the 1960s and more recently prescribed as an anti-depressant at low doses. They have identified an entirely new class of receptors that ketamine binds in the body, which may underlie its diverse actions. —> Read More

What’s The Difference Between Sugar And High Fructose Corn Syrup?

High fructose corn syrup has been a somewhat mysterious ingredient ever since the 1970s.

It was introduced to the market at a time just as corn farmers began to receive subsidies (a practice that’s still in place today), making it a much cheaper ingredient than sugar. Unlike sugar, which comes from a plant, HFCS is formed from an intricate chemical process, which breaks down corn into a sweetener. Despite the process in which they’re made, sugar and HFSC have little nutritional differences. Learn more about these two sweeteners in video above, which was produced by the American Chemical Society. —> Read More

Google Makes You Think You’re Smarter Than You Actually Are

Google puts a nearly infinite amount of knowledge at our fingertips, but a new study says that the search engine isn’t making us any smarter.

Internet searches give people the illusion of personal knowledge even when they haven’t actually gained any, according to a new study published this week in the Journal of Experimental Psychology.

“Unlike looking something up in a book or calling up a friend for the answer to a question, searching the Internet is nearly effortless,” Matthew Fisher, a doctoral candidate in psychology at Yale University and the study’s lead author, told The Huffington Post in an email. “The Internet is always available and gives instant answers, making people less aware of just how reliant they are on it.”

In a series of experiments, participants searched for information on the Internet, such as the answer to the question “How does a zipper work?” They then answered questions about their perceptions of the knowledge they had gained.

The findings revealed that people who had searched for information online believed themselves to be more knowledgeable than a control group about topics that were completely unrelated to what they had just Googled. After a brief Internet search, the participants also perceived their brains to be more active than the control group, who didn’t use the Internet. What’s more, the participants had an inflated sense of personal knowledge and brain activity even when they couldn’t find the information they were looking for.

The Internet blurs the line between what we know and what we think we know, the researchers concluded.

According to the study, people tend to confuse their own knowledge with that of the Internet, which has become a sort of external hard drive for the brain, holding much of the important information and memories that we rely on.
