'Honeycomb' of nanotubes could boost genetic engineering

Researchers have developed a new and highly efficient method for gene transfer. The technique, which involves culturing and transfecting cells with genetic material on an array of carbon nanotubes, appears to overcome the ...

Experimental treatment regimen effective against HIV

Protease inhibitors are a class of antiviral drugs that are commonly used to treat HIV, the virus that causes AIDS. Scientists at the University of Nebraska Medical Center designed a new delivery system for these drugs that, ...

Are male brains wired to ignore food for sex?

Choosing between two good things can be tough. When animals must decide between feeding and mating, it can get even trickier. In a discovery that might ring true even for some humans, researchers have shown that male brains ...

Scientists find a key to maintaining our DNA

DNA contains all of the genetic instructions that make us who we are, and maintaining the integrity of our DNA over the course of a lifetime is a critical, yet complex part of the aging process. In an important, albeit early ...

Unexpected find opens up new front in effort to stop HIV

HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned. While the finding helps explain why HIV remains such a formidable foe after three decades of ...
