Harmless virus may hold key to more effective HIV drug discovery
...ds are tested in the clinic, which is currently an expensive
and time-consuming process." The Weiss laboratory specializes in developing massive libraries of proteins that can potentially target and bind to other proteins, using a process called phage display. In this study, Weiss and Olszewski first created o...
New dye could offer early test for Alzheimer's

Towards a cheap and easy way to monitor HIV/AIDS
..., the existing reliable CD4 counters are large and expensive
pieces of equipment, and every actual count is not only expensive
but also requires considerable expertise. These tools are therefore unsuitable for many low-income c...

Costly breeding programs for endangered species pay off
.... Though the findings clearly support the case for expensive
MAI breeding schemes for some endangered animals, Meffert suspects that might not be the case for species that reproduce faster or have larger broods. For those animals, alternate breeding schemes might indeed prove more effective, and her group is c...
