New electromechanical transducers with high energy output, high strains, high mechanical compliance, lightweight, damage-tolerance and low cost can enable needed advances in a variety of applications, such as robotics, automation and biomedical devices. The perceived need for improved transducer performance, which has progressively emerged in the last few decades, has drawn considerable efforts for the development of devices relying on materials with intrinsic transduction properties.
From all of these perspectives, the evidence gathered by the Review leads to a
simple conclusion: the benefits of strong, early action considerably outweigh the
The evidence shows that ignoring climate change will eventually damage economic
growth. Our actions over the coming few decades could create risks of major
disruption to economic and social activity, later in this century and in the next, on a
scale similar to those associated with the great wars and the economic depression of
the first half of the 20th
century. And it will be difficult or...
Ovarian cancer is the most common fatal cancer of the female reproductive tract in
industrialized countries. At the time of writing, it is the fourth most common cause of
cancer death in women in the U.K., after breast, lung, and colorectal cancer, with a
lifetime risk of approximately 2% (1). It tends to present at an advanced stage, with
limited prospects for treatment and generally poor survival.

Hypoxic preconditioning may afford protection against subsequent lethal
hypoxia. As hypoxic tolerance induces changes in the expression of genes
involved in DNA damage and repair response pathways, we investigated
whether DNA-dependent protein kinase (DNA-PK), one of the DNA dou-ble-strand break repair proteins, could be involved in hypoxic precondi-tioning-induced protective signaling cascades.
