Pollutants key to climate fix

To Fix or Not to Fix? That is the Question.

Eventually, the algorithm for when to intervene on the tricuspid valve during left sided valve surgery will be more robust. Better discriminatory preoperative data will be required to sort the role of annular size, right ventricular function, and pulmonary artery pressures. As for now, there is a paucity of evidence that an aggressive approach to fixing moderate functional TR during left sided ...

The arctic: a key to world climate.

American Association for the Advancement of Science Science serves its readers as a forum for the presentation and discussion of important issues related to the advancement of science, including the presentation of minority or conflicting points of view, rather than by publishing only material on which a consensus has been reached. Accordingly, all articles published in Science-including editor...

Brains at necropsy: to fix or not to fix?

AIM To investigate whether routine formalin fixation of all brains coming to necropsy increases the rate of detection of brain abnormalities relative to either selective formalin fixation of brain tissue or fresh dissection of all brain tissue at the time of post mortem examination. METHODS A retrospective study of 300 medicolegal necropsies was performed. One hundred cases were examined by d...

Designing an Optimal ' Tech Fix ' Path to Global Climate Stability : R & D in a Multi ‐ Phase Climate Policy Framework

The research reported here gives priority to understanding the inter‐temporal resource allocation requirements of a program of technological changes that could halt global warming by completing the transition to a “green” (zero net CO2‐ emission) production regime within the possibly brief finite interval that remains before Earth’s climate is driven beyond a catastrophic tipping point. This pa...
