Most paleontologists agree that birds are descended from dinosaurs. How did such large terrestrial or aquatic animals evolve into small feathered fliers? Lee et al. used two – [Read More]

Some patients with breast cancer respond to therapy with trastuzumab, but many later develop resistance. Breast tumors often lack SIRT6, which encodes an enzyme that is a tumor suppressor. – [Read More]

Perovskite films received a boost in photovoltaic efficiency through controlled formation of charge-generating films and improved current transfer to the electrodes. Zhou et al. – [Read More]

Even in the face of a cocktail of antiretroviral drugs, HIV manages to hang on. It does so by integrating its own genome into those of host cells, where it persists in a latent state. – [Read More]
