What are mitochondria and how did we come to have them?

We've probably all heard of mitochondria, and we may even remember learning in school that they are the "powerhouses of the cell" – but what does that actually mean, and how did they evolve? To answer this question, we ...

Study reveals how HIV enters cell nucleus

Loyola University Chicago scientists have solved a mystery that has long baffled HIV researchers: How does HIV manage to enter the nucleus of immune system cells?

Genetics

Research shows hope for personalized genome sequencing

Imagine if you could carry a credit card-size record of all the 3 billion A's, T's C's, and G's that make up the alphabet soup of your genome. A simple swipe of the card could inform your physician right away if a drug being ...

A new understanding of Alzheimer's

Although natural selection is often thought of as a force that determines the adaptation of replicating organisms to their environment, Harvard researchers have found that selection also occurs at the level of neurons, which ...
