DNA damage is one of the most deleterious forms of cellular damage. If unrepaired, DNA lesions can create genomic instability, a hallmark of cancer . As most of the DNA is confined to the nucleus, for many years the study of DNA damage response has mainly focused on its nuclear effects, including mechanisms such as […]
Approximately 90% of world’s electricity is generated in turbines moved by hot steam, which, unfortunately, operate only at 30 to 40 percent efficiency. This means that around two thirds of the total energy input is lost into the environment as waste heat. Thermoelectric materials can convert such waste heat into useful electricity, although they are […]
