My last post is not research, but it is very applicable to everyones’ lives. I hope every gets a chance to watch it. Meg Jay discusses how our generation thinks that everyone will just have it all figured out in their 30’s, but this is isn’t the case! What we do now is our future, so take advantage of your 20’s. As she discusses, this is the most critical time for all young adults to develop into who they want to be in the future. Good luck to everyone!
This post is obviously inspired by the presentors in todays class. And maybe I didn’t use “SCIENCE,” but I definitely thought of this first. My thought was that they should develop an insulin that would only direct cells to uptake glucose in high blood glucose concentrations. This article obviously does a much better job at actually defining the research. Either way, they need to move to human trials ASAP, and I’ll be the first to volunteer.
Loneliness undermines peoples ability to self regulate. One study found that those who reported to feel socially disconnected ate many more cookies than those who didn’t. “We want to soothe the pain we feel by mainlining sugar and fat content to the pleasure centers of the brain, and absent of self-control, we go right at it.” Thus, the stereotypical eating of icecream while watching some sappy movie after a break-up; induced by the sudden disconnect with social groups. Click the picture, pretty interesting article that I felt like was easy for most readers to relate to.
A new study found that eating more fatty foods was linked to sleepiness. Those that opted for high carb substitutes saw a dramatic rise in alertness. Click the picture for the article.
In the NY Times, I read an article that talked about how women that are genetically predisposed to getting breast cancer, are now opting to get a preventative procedure to avoid breast cancer. Doctor’s can predict that some women may have a 90% chance of getting breast cancer, and a 50% of getting ovarian cancer, after getting tested for the BRCA1 and BRCA2 genes. This article is also a clear indication that research efforts should focus on diagnostic technologies. Unfortunately, most of our cancer detection technologies are harmful in themselves, making frequent observation of patients counter productive.
New companies like Lumosity have over 40 million members online, to improve their brain function. Although there is often unclear results on whether brain training just improves one’s skill at a particular game, or if the skills actually translate to real world application.

I’m not sure how this really relates to biology research, but I thought it was too cool to not post. A group of Norwegian scientists from the SINTEF organization proposed a new design that may actually go into production. Utilizing the immense pressure at sea floor bottoms, the force could drive a turbine, which in turn could produce electricity for thousands of people. Go green.
Researchers at General Electric created a new 3-D image technology called HDlive. It utilizes an ultrasound that creates a clear and colorful 3-D image of a fetus in utero. Who wants to wait 9 months to see their beautiful son or daughter? This is America. But actually, the technology allows doctors to more accurately access the fetus’s health and foresee potential complications.
Researchers are developing a machine that could replace animal testing altogether. The organ simulator is designed to simulate the lung, heart, kidney, intestine, pancreas, skin and bone marrow. Each chip is designed to consist of reservoirs, channels, and membranes lined with human cells. Scientists can monitor the cells’ response to different fluid and air stimuli, to gauge the effect on actual human beings.
A study published this week in the journal Cell reported to have successfully created human stem cells. Using a cloning technique, the one that was used to create Dolly, researchers transplanted genetic material from an adult cell into a human egg cell that had its DNA removed. The “hybrid” cell proliferated until the blastocyst state, in which they await differentiation into specific cell types. These cloning techniques has lead to scientists producing the embryonic stage of stem cells, while side-stepping the problem of harvesting fertilized human eggs. Quite the accomplishment which has the potential to turn stem cell research into full stem cell treatments.
