E tubes coated with silver, which has shown potent broad-spectrum antimicrobial activity in vitro, reduced the incidence of ventilatorassociated pneumonia by 35% in a multicenter study, researchers reported. “This is the first intervention demonstrated to reduce ventilator-associated pneumonia incidence that does not require more effort or supervision from clinicians providing bedside care,” sa...

species of chameleon, Furcifer labordi, in Madagascar that spends most of its life as an egg. in Madagascar and the American Museum of Natural History in New York, have found a chameleon with a remarkable lifestyle and report the results in the latest issue of the Proceedings of the National Academy of Sciences (published online).

This paper will cover a general discussion of changes and improvement in software. I will focus on some special aspects of the evolutionary process, and propose to extend those techniques and approaches.

Posner`s (2010) analysis offers many exciting insights into the principal-agent problem, particularly with respect to the secret service. I argue that it would be useful to consider a broader model of human behaviour, which includes awards as extrinsic incentives beyond pay, as well as intrinsic motivation. A more comparative stance that goes beyond the United States would be a useful check of ...

Living systems are perhaps the most fascinating examples of chemistry in action. Molecules assemble into biomachinery that can carry out complex tasks, making life possible. But how did it all begin? This question can be tackled from a geological perspective by surveying the possible conditions under which key biomolecules might have emerged on early Earth. Alternatively, a systems-biology appr...

Author's note: I have written this anonymously because I do not want harm to come to those who helped me get my results. It is my hope that my travails will call attention to the fact that patient access to what one has a right to know about oneself is not necessarily str...

Knowledge bases such as Wikidata, DBpedia, YAGO, or the Google Knowledge Vault collect a vast number of facts about the world. But while quite some facts are known about the world, little is known about how much is unknown. For example, while the knowledge base may tell us that Barack Obama is the father of Malia Obama and Sasha Obama, it does not tell us whether these are all of his children. ...

A challenge for educators is to fuse the learning of information literacy to an academic education in such a way that the outcome is systematic and sustainable learning for students. This challenge can be answered through longterm commitment to information literacy education bound to organisation-wide, renewable strategic planning and driven through systemic reform. This paper explores the proc...
