Researchers have developed a technique for creating nanoparticles that carry two different cancer-killing drugs into the body and deliver those drugs to separate parts of the cancer cell where they will be most effective. The technique was ...

For the estimated 10 percent of patients whose bodies reject a corneal transplant, the odds of a second transplant succeeding are poor. All that could change, however, based on a UT Southwestern Medical Center study that has found a way to ...

We are fundamentally dependent on the presence of copper in the cells of the body. Copper is actually part of the body's energy conversion and protective mechanisms against oxygen radicals, as well as part of the immune system, and it also ...

Roughly 40 percent of all medications act on cells' G protein-coupled receptors (GPCRs). One of these receptors, beta 2 adrenergic receptor site (B2AR), naturally transforms between two base configurations; knowing the precise location of ...

In a maze of blindingly complex reactions that snap oxygen atoms off cellulose or other bio-sources to create energy-dense fuel, the starting molecule's size has a curious effect. If the oxygen-rich molecule is too short to comfortably ...

One of the most widely known compounds on Earth is carbon dioxide, or CO2. We learn as children that CO2 is a key component of photosynthesis, the process by which plants, algae, and bacteria convert light into energy. This reaction is part ...
