Astronomers Reveal Secrets of Most Distant Supernova  

Southampton, UK (SPX) Feb 21, 2018 An international team of astronomers led by the University of Southampton has confirmed the discovery of the most distant supernova ever detected - a huge cosmic explosion that took place 10.5 billion years ago, or three-quarters the age of the universe itself. The exploding star, named DES16C2nm, was detected by the Dark Energy Survey (DES) (an internati

Why Partisanship Is Such a Worthy Foe of Objective Truth  

The truth is out there, but if it doesn't come from "my side" who cares? In an era of "fake news" our relationship status with factual knowledge, and a shared reality has changed to "it's complicated". Democracies depend on informed populations, but objective truth has of late taken a back seat to partisanship. In an essay published in Cell Press Reviews, New York University psychologists Jay Van Bavel and Andrea Pereira attempt to demystify how partisan bias has skewed th...

Resolvin D-1 limits kidney damage after heart attacks  

A heart attack triggers an acute inflammatory response at the damaged portion of the heart's left ventricle. If the inflammation lingers, it can lead heart failure. The inflammation can also claim another victim -- the kidneys. New research shows that a bioactive compound called resolvin D-1, injected as a therapeutic dose, is able to limit this collateral damage in the kidneys, as tested in an animal model. This suggests potential application to the clinical setting.
