What Can a Flower Tell You About Cancer?

What does this flower tell you about cancer?

The arabidopsis thaliana, or the mouse-ear cress, is often studied by biologists because of it’s small genome. Northeastern University’s Albert-László Barabási, a bioinformatics pioneer has come up with a mathematical algorithm to identify communities in complex networks, including major biological networks and large-scale social networks. Barabási recently used his algorithm on the plant, according to the article

“…combing through about 6,200 highly reliable interactions between about 2,700 proteins, and came up with about two dozen communities of interconnected proteins that share in the same biological function. The findings give researchers a peak inside evolution’s machinery within networks of plant proteins. “The communities were not random and each had a dominant function that did not emerge by chance,” Barabási said in a news release.”

How does that help with cancer? The protein communities Barabási identified allow the scientific community a peek into how to treat human diseases like cancer.

How Alcohol Can Ruin Your Sleep

August 1, 2011

Do you typically finish out your evening with a nightcap but still wake up feeling unrefreshed?

Check out an excerpt of  NeuroTrials CEO Dr. Russell Rosenberg‘s latest contribution to the Huffington Post below. Then head over to the Huffington Post for the full article and join the discussion.

Using alcohol to get to sleep is by no means a new concept. Despite advances in sleep medicine, many people with trouble initiating or maintaining sleep self-medicate with alcohol and accept the consequences of fitful or unfulfilling sleep. In fact, it was not that long ago that physicians recommended “night caps” for insomniacs or others experiencing sleep problems. Using alcohol for sleep is a bad idea because it can affect sleep stages, lighten sleep and cause abrupt awakenings. Chronic use of alcohol may lead to needing higher and higher doses to achieve the same sleep-inducing effect.
