Using living cells as more efficient tools for delivering medicines  to diseased parts of the body has  gotten a little closer.   

In a new report, Dayang Wang and colleagues explain that the human body's efficiency in getting rid of foreign substances can also be an obstacle. Some foreign substances, such as viruses, are harmful and should obviously be removed, but the body also considers drugs and nanoparticles — meant to treat diseases and allow physicians to see cells and organs — to be foreign objects, and they are also quickly removed.

Only nostalgia zealots can argue we are not in a Golden Age for animated movies. 2010 gave us classics like "Megamind", "Toy Story 3" and the one movie to rule them all, "Tangled." These awesome animated family movies are just a few of the reasons why we are in the Golden Age of cartoons, and we do not even have to include "The Incredibles", "Finding Nemo", or "Up". The characters and story had heart and compelling plots.

They also had physics.
A new study in Cell shows that Wnt signaling, already known to control many biological processes, between hair follicles and melanocyte stem cells can dictate hair pigmentation.

Using genetic mouse models, researchers were able to examine how Wnt signaling pathways enabled both hair follicle stem cells and melanocyte stem cells to work together to generate hair growth and produce hair color.

Research also showed the depletion (or inhibition or abnormal) Wnt signaling in hair follicle stem cells not only inhibits hair re-growth but also prevents melanocytes stem cell activation required for producing hair color. The lack of Wnt activation in melanocyte stem cells leads to depigmented or gray hair.
A diet low in carbohydrates and high in protein may reduce the risk of cancer and slow the growth of tumors already present, according to a study published in Cancer Research.
The study was conducted in mice but the scientists believe the strong biological findings warrant that a similar effect in humans can be considered. 
Perceptions of racism may cause loss of sleep and perhaps loss of sleep may also impact perceptions of racism.

A new study has found that self-reported sleep disturbance correlated to perceived racism, which was increased by 61 percent after adjusting for socioeconomic factors and symptoms of depression. A similar relationship between perceived racism and daytime fatigue was no longer significant after additional adjustment for depressive symptoms.
Lady Gaga is a marketing-fueled pop music phenomenon.   If you exclude her music, she can do no wrong, and every appearance, even a walk through an airport, is carefully choreographed.   She knows her audience.

But a Little Monster could help create the next Lady Gaga in a more direct way.  A new study suggests that the brain activity of teens while they are listening to new songs may help predict the popularity of those songs.
