The heart pumps oxygen-rich blood to all of the organs in the body to keep them functioning. But, how does the heart's own muscle get the oxygen-rich blood that it needs to keep the heart pumping? This paper describes how the ...Read More
A reader asks: "I was listening to NPR recently and I heard a wildlife biologist speculate on something (I can't recall what exactly) and she followed up her speculation with, "but that's just a theory." I have always thought that such ...Read More
I've taken a short vacation from blogging but am back and ready to start talking about science again. I'll have a new paper overview up soon, but in the mean time, here are a few interesting articles that have come ...Read More
Organisms need to efficiently create new proteins in order to continue to function. In this paper, the authors find that the actual sequence of DNA influences the processes that occur in translation into proteins. Read More
Some organisms are able to regenerate damaged or missing body parts. This paper looks at how the regeneration process occurs in zebrafish hearts. Read More
A reader asks: Is it possible for two siblings to be genetically identical without one fertilized egg splitting into two separate embryos? Read More
How does an embryo that is still a ball of cells decide which way is up and which is down? A number of genes actively work to solve just this problem. In this paper, the authors examine the genes involved ...Read More
Patients with HIV are known to have problems fighting infections. This paper looks into some of the reasons this might occur and finds some suprising results. Read More
In science news, today we are bringing you two articles about two totally different topics: toys and personalities! Read More
If a concept is so important as to be named the Central Dogma of a field as huge as molecular biology, it’s probably safe to say that it is something worth knowing a little bit about if you’re a science-curious ...Read More
